Complications After Open Reduction and Internal Fixation for Distal Radius Fractures in Patients With and Without Rheumatoid Arthritis

PURPOSE

Rheumatoid arthritis (RA) can have severe impact on patients' functional abilities and increase the risk of fragility fractures. Little is known about how patients with RA fare after operative management of distal radius fractures. The purpose of this study was to compare postoperative complications after surgical fixation in patients with RA and controls, hypothesizing that patients with RA would have higher levels of postoperative complications.

METHODS

Patients were identified using Current Procedural Terminology and International Classification of Diseases, Ninth and Tenth Revision, codes for open treatment of distal radius fractures and RA at 3 level 1 trauma centers over a 5-year period (2015-2019). Chart abstraction provided details regarding injuries and treatment. Age- and sex-matched controls were identified in a 2:1 ratio. Postoperative complications were classified according to the Clavien-Dindo-Sink classification system and divided into early (less than 90 days) and late groups.

RESULTS

Sixty-four patients (21 with RA and 43 controls) were included. The patients were predominantly women, with a mean age of 62 years and a mean Charlson comorbidity index of 2.1. The RA medications at the time of injury included conventional synthetic disease-modifying antirheumatic drugs (5/21), biologic disease-modifying antirheumatic drugs (5/21), or chronic oral prednisone (6/21). Rheumatoid medications, except hydroxychloroquine, were withheld for 2-3 weeks after surgery. Rheumatoid patients were significantly more likely to sustain a complication compared with the control group, although this was no longer significant on adjusted analysis. Class I complications were the most common. The incidence of early versus late complications was similar between the groups. A high rate of early return to surgery for fixation failure occurred in the RA group compared with none in the control group.

CONCLUSIONS

Patients with RA undergoing operative management of distal radius fractures are at risk of postoperative complications, particularly fracture fixation failure, necessitating return to the operative room. High levels of pain, stiffness, and mechanical symptoms were noted in the RA group.

The Significance of Subjective Mechanical Symptoms in Rotator Cuff Pathology

BACKGROUND

The presence of subjective mechanical symptoms, such as clicking or popping, is common in patients presenting for shoulder pain and dysfunction, with unclear clinical significance. The primary objective of this study was to assess whether subjective mechanical symptoms in the affected shoulder were associated with full-thickness rotator cuff tearing in a consecutive, prospective cohort of patients undergoing shoulder magnetic resonance imaging (MRI) for suspected rotator cuff pathology.

METHODS

A prospective cohort study was performed of 100 consecutive patients with suspected rotator cuff tendinopathy and/or tearing who underwent shoulder MRI. The presence of subjective shoulder mechanical symptoms, including clicking or popping, was documented prior to MRI. Indications for MRI included weakness on isolated testing of rotator cuff muscle(s) or symptoms refractory to conservative treatment including at least a 6-week course of physical therapy. The primary outcome variable was the presence of full-thickness rotator cuff tearing; secondary outcome variables included any (full-thickness or partial-thickness) rotator cuff tearing and biceps long head subluxation. Radiographic parameters, including critical shoulder angle, Goutallier grade, tear retraction, and tear size were quantified. One patient was lost to follow-up, and 99 patients completed MRI imaging.

RESULTS

In our cohort, 60% of patients reported subjective mechanical symptoms in the affected shoulder. Full-thickness rotator cuff tearing was identified in 42% of patients, any rotator cuff tearing in 69% of patients, and biceps long head subluxation in 14% of patients. Subjective mechanical symptoms were not associated with full-thickness rotator cuff tearing, any rotator cuff tearing, biceps long head subluxation, critical shoulder angle, Goutallier grade, tear size, or tear retraction. Older age was associated with full-thickness and any rotator cuff tearing. As a diagnostic test for full-thickness rotator cuff tearing, subjective shoulder mechanical symptoms has a sensitivity of 64%, a specificity of 44%, and Youden's index of 0.08, consistent with poor diagnostic accuracy.

CONCLUSIONS

Subjective mechanical symptoms in the affected shoulder are a common complaint in patients with suspected rotator cuff pathology. Patients may be reassured that a sensation of clicking or popping alone does not necessarily entail structural shoulder derangement.

The Relationship Between Preoperative International Normalized Ratio and Postoperative Major Bleeding in Total Shoulder Arthroplasty

INTRODUCTION

This study aimed to assess the relationship between preoperative international normalized ratio (INR) levels and major postoperative bleeding events after total shoulder arthroplasty (TSA).

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database was queried for TSA from 2011 to 2020. A final cohort of 2405 patients with INR within 2 days of surgery were included. Patients were stratified into four groups: INR ≤ 1.0, 1.0 < INR ≤ 1.25, 1.25< INR ≤ 1.5, and INR > 1.5. The primary outcome was bleeding requiring transfusion within 72 hours, and secondary outcome variables included complication, revision surgery, readmission, and hospital stay duration. Multivariable logistic and linear regression analyses adjusted for relevant comorbidities were done.

RESULTS

Of the 2,405 patients, 48% had INR ≤ 1.0, 44% had INR > 1.0 to 1.25, 7% had INR > 1.25 to 1.5, and 1% had INR > 1.5. In the adjusted model, 1.0 < INR ≤ 1.25 (OR 1.7, 95% CI 1.176 to 2.459), 1.25 < INR ≤ 1.5 (OR 2.508, 95% CI 1.454 to 4.325), and INR > 1.5 (OR 3.200, 95% CI 1.233 to 8.302) were associated with higher risks of bleeding compared with INR ≤ 1.0.

DISCUSSION

The risks of thromboembolism and bleeding lie along a continuum, with higher preoperative INR levels conferring higher postoperative bleeding risks after TSA. Clinicians should use a patient-centered, multidisciplinary approach to balance competing risks.

Impact of an Outpatient Fracture Liaison Service on Osteoporosis Evaluation Among Patients With Upper Extremity Fragility Fracture

BACKGROUND

The purpose of this study was to assess the impact of implementation of an outpatient fracture liaison service (FLS) on completion rates of dual-energy x-ray absorptiometry (DXA) and screening labs including 25-OH vitamin D and parathyroid hormone (PTH) in patients with upper extremity (UE) fragility fractures.

METHODS

At our institution, 367 patients were treated in 2014-2015 for UE fragility fractures of the distal radius and proximal humerus before implementation of our outpatient FLS and 395 patients in 2017-2018 after implementation. Retrospective chart review was conducted to identify completed DXA scans within 2 years of fracture treatment and completed 25-OH vitamin D and PTH labs within 1 year of fracture treatment.

RESULTS

There were no statistical differences in the demographics of patients treated for distal radial and proximal humeral fragility fractures during the 2014-2015 and 2017-2018 time periods. Implementation of the FLS resulted in a 9.9% increase (P value = .021) in completed DXA scans within 2 years of fracture treatment. Completed 25-OH vitamin D and PTH labs saw a significant increase of 17.1% and 23.8%, respectively (P values < .001).

CONCLUSIONS

Implementation of an outpatient FLS can help to improve osteoporosis evaluation with completed DXA scans and 25-OH vitamin D and PTH labs.

Factors Influencing Patient Preference for Anesthesia in Ambulatory Hand Surgery

BACKGROUND

The purpose of this study was to identify factors that influence preoperative patient preferences toward anesthesia in patients in a hand and upper extremity clinic.

METHODS

A survey was administered to consecutive patients in a hand and upper extremity orthopedic clinic at an urban tertiary academic institution. The survey addressed presenting clinical complaint, anesthesia preference for minor soft tissue hand and wrist procedures, factors influencing anesthesia preference, and patient history of anesthesia and surgical treatment. The primary outcome measure was anesthesia preference: local-only or local with sedation.

RESULTS

Surveys were completed by 219 patients over a 1-month period with a mean patient age of 55 years. Most patients presented with a hand/wrist complaint (56%). One hundred fifty-two patients (71%) preferred local anesthesia with sedation and 61 patients (29%) preferred local-only anesthesia. Patients who preferred local-only anesthesia reported being more likely to be influenced by surgeon preference and cost, and also were more likely to have had prior experience with local-only anesthesia. In contrast, patients who preferred local anesthesia with sedation were more likely to be concerned about pain or were nervous about surgery. Prior surgical experience did not influence preference for anesthesia.

CONCLUSION

Patient preferences for local-only anesthesia versus local anesthesia with sedation for ambulatory hand surgery are mixed, with most patients preferring sedation. Understanding patient preferences for anesthesia can better inform preoperative discussions and shared decision-making in anesthesia choice.

Risk Factors for Rescue Opioid Prescription After Cubital Tunnel Surgery

BACKGROUND

Concerns regarding the ongoing opioid epidemic have led to heightened scrutiny of postoperative opioid prescribing patterns for common orthopedic surgical procedures. This study investigated patient- and procedure-specific risk factors for additional postoperative opioid rescue prescriptions following ambulatory cubital tunnel surgery.

METHODS

A retrospective review was performed of patients who underwent cubital tunnel surgery at 2 academic medical centers between June 1, 2015 and March 1, 2020. Patient demographics, comorbidities, prior opioid history, and surgical variables were recorded. The primary outcome was postoperative rescue opioid prescription. Univariate and bivariate statistical analyses were performed.

RESULTS

Two hundred seventy-four patients were included, of whom 171 (62%) underwent in situ ulnar nerve decompression and 103 (38%) underwent ulnar nerve decompression with anterior transposition. The median postoperative opioid prescription amount was 90 morphine equivalent units (MEU) for the total cohort, 77.5 MEU for in situ ulnar nerve decompression, and 112.5 MEU for ulnar nerve decompression with transposition. Twenty-two patients (8%) required additional rescue opioid prescriptions postoperatively. Female sex, fibromyalgia, chronic opioid use, chronic pain diagnosis, and recent opioid were associated with the need for additional postoperative rescue opioid prescriptions.

CONCLUSIONS

While most patients do not require additional rescue opioid prescriptions after cubital tunnel surgery, chronic pain patients and patients with pain sensitivity syndromes are at risk for requiring additional rescue opioid prescriptions. For these high-risk patients, preoperative collaboration of a multidisciplinary team may be beneficial for developing a perioperative pain management plan that is both safe and effective.

Carpal Tunnel Syndrome Electrodiagnostic Severity is Not Associated with PROMIS Upper Extremity, PROMIS Pain Interference and PROMIS Pain Intensity

Background: The primary objective of this study was to determine the association between preoperative electrodiagnostic study (EDS) parameters and Patient-Reported Outcomes Measurement Information System (PROMIS) instruments in patients with EDS-confirmed carpal tunnel syndrome (CTS). Methods: A retrospective study of 45 patients with EDS-confirmed CTS was conducted. Patients completed the PROMIS Upper Extremity, PROMIS Pain Interference and PROMIS Pain Intensity. Explanatory variables included EDS disease severity (mild, moderate and severe), sensory peak latency, sensory amplitude, motor latency, motor amplitude, the presence of nonrecordable sensory latency and the presence of nonrecordable sensory amplitude. Explanatory variables also included patient-related factors, such as age, sex and diabetes mellitus. Associations between variables were assessed using simple linear regression, analysis of variance (ANOVA) and Student's t-test. Results: In our cohort, the EDS severity was mild in 38%, moderate in 42% and severe in 20% of patients. The mean PROMIS Upper Extremity score was 44.4, the mean PROMIS Pain Interference score was 53.5 and the mean PROMIS Pain Intensity score was 49.9. Bivariate analysis demonstrated no association between EDS severity overall or any EDS parameter individually and PROMIS Upper Extremity, PROMIS Pain Interference and PROMIS Pain Intensity. Diabetes mellitus was associated with poorer PROMIS Upper Extremity scores. Conclusions: EDS severity is not associated with PROMIS Upper Extremity, PROMIS Pain Interference and PROMIS Pain Intensity. Carpal tunnel release is commonly indicated for pain and dysfunction, but validated measures of pain and dysfunction do not correlate with EDS severity. Level of Evidence: Level III (Diagnostic).

A Near-Miss in Clinical Outcomes Research Data Collection

ABSTRACT

We present the case of a near-miss in clinical research to illustrate a situation in which errors in data collection would have led to different results in the data analysis, with the potential for drawing incorrect conclusions. Conclusions based on data errors may adversely influence future medical decision-making in patient care. In the interest of presenting this as an educational, nonpunitive, quality-improvement report, the study and the involved researchers remain anonymous, and the specific details and exact number of patients are not reported.

Successful aging after elective surgery II: Study cohort description

BACKGROUND

The Successful Aging after Elective Surgery (SAGES) II Study was designed to examine the relationship between delirium and Alzheimer's disease and related dementias (AD/ADRD), by capturing novel fluid biomarkers, neuroimaging markers, and neurophysiological measurements. The goal of this paper is to provide the first complete description of the enrolled cohort, which details the baseline characteristics and data completion. We also describe the study modifications necessitated by the COVID-19 pandemic, and lay the foundation for future work using this cohort.

METHODS

SAGES II is a prospective observational cohort study of community-dwelling adults age 65 and older undergoing major non-cardiac surgery. Participants were assessed preoperatively, throughout hospitalization, and at 1, 2, 6, 12, and 18 months following discharge to assess cognitive and physical functioning. Since participants were enrolled throughout the COVID-19 pandemic, procedural modifications were designed to reduce missing data and allow for high data quality.

RESULTS

About 420 participants were enrolled with a mean (standard deviation) age of 73.4 (5.6) years, including 14% minority participants. Eighty-eight percent of participants had either total knee or hip replacements; the most common surgery was total knee replacement with 210 participants (50%). Despite the challenges posed by the COVID-19 pandemic, which required the use of novel procedures such as video assessments, there were minimal missing interviews during hospitalization and up to 1-month follow-up; nearly 90% of enrolled participants completed interviews through 6-month follow-up.

CONCLUSION

While there are many longitudinal studies of older adults, this study is unique in measuring health outcomes following surgery, along with risk factors for delirium through the application of novel biomarkers-including fluid (plasma and cerebrospinal fluid), imaging, and electrophysiological markers. This paper is the first to describe the characteristics of this unique cohort and the data collected, enabling future work using this novel and important resource.

Clinic Study Completion Rate in Orthopedic Surgery

Purpose

The primary aim of this study is to determine the rate of completion of clinic-based study orders. Secondarily, we attempt to determine factors associated with study incompletion.

Methods

This retrospective study included 591 clinic-based studies that were ordered for 510 patients at the time of clinical evaluation at a single medical center between April 8, 2018 and August 22, 2019. Inclusion criteria were studies ordered in a hand clinic for consecutive adult patients to be completed after the visit. Exclusion criteria included pediatric patients and routine radiographs obtained prior to the visit. Invasive studies were defined as studies with a significant procedural component, such as aspirations, injections and electromyography/nerve conduction (electrodiagnostic) studies (EDS). Blood tests and imaging were considered noninvasive. Patient demographics and study completion rates were collected through chart reviews. Univariate and bivariate analyses were performed, and P <.05 was considered significant.

Results

The overall clinic-based study completion rate was 94.2%, with the highest incompletion rates seen in invasive studies (8.3%, n = 34) compared to noninvasive studies (3.3%, n = 10). Within the invasive study category, EDS had the highest rate of incompletion (11.4%) and contributed to the majority of incompletions in the invasive cohort (20/24). The median time to study completion was 7 days (interquartile range [IQR] 2-21). Race, gender, English as primary language, marriage status, insurance type, and distance from facility were similar between completed and noncompleted studies.

Conclusion

Study completion rates were similar between all patients regardless of race, gender, and other social economic variables. Invasive studies, particularly EDS, had higher rates of incompletion and can be barriers to patients receiving additional care.

Collagenase Treatment Versus Needle Fasciotomy for Single-Digit Dupuytren Contractures: A Meta-Analysis of Randomized Controlled Trials

PURPOSE

The objective of this systematic review and meta-analysis was to synthesize the available randomized controlled trial data comparing needle fasciotomy and collagenase treatment for single-digit Dupuytren contractures with a minimum of 3-year follow-up and determine whether one treatment is superior regarding contracture correction and functional outcomes.

METHODS

A systematic review and meta-analysis was conducted by searching four databases for randomized controlled trials investigating the single-digit treatment outcomes for Dupuytren contracture comparing collagenase treatment and needle fasciotomy with a minimum of 3-year follow-up. The risk of bias of included studies was assessed using the Cochrane risk-of-bias tool. A meta-analysis was performed using a random effects model in anticipation of unobserved heterogeneity. The primary outcome measure was contracture recurrence. Secondary outcome measures included final fixed flexion contracture (FFC), Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores, and Unité Rhumatologique des Affections de la Main (URAM) scores.

RESULTS

After screening 264 articles, 4 randomized clinical trials were eligible for final inclusion. One trial had a high risk of bias, and two trials had some concern for bias. The final meta-analysis included 347 patients, 169 who underwent collagenase treatment and 178 who underwent needle fasciotomy. No significant differences were noted between the groups in contracture recurrence, FFC, and URAM scores. The pooled data showed a higher QuickDASH score in the collagenase treatment group compared with the needle fasciotomy group, but the observed difference was less than what would be expected to be clinically relevant.

CONCLUSIONS

Needle fasciotomy and collagenase treatment have similar outcomes with regards to contracture recurrence, final FFC, QuickDASH scores, and URAM scores for the single-digit treatment for Dupuytren contracture at a minimum of 3-year follow-up. Relevant factors that may be considered during the shared decision-making process for treatment selection include surgeon and patient preferences, costs of treatment, and the disparate complication profiles of these two treatments.

Future Fracture Risk in Upper Extremity Fracture and Non-Fracture Patients

BACKGROUND

Upper extremity (UE) fragility fractures are common and strong predictors of subsequent fractures. To investigate the relative importance of an UE fragility fracture in determining future fracture risk, we conducted a cross-sectional study to compare future fracture risk between patients presenting for osteoporosis evaluation after an UE fragility fracture and a similarly aged cohort of patients without an UE fracture.

METHODS

In all, 129 UE fracture patients seen in our bone health clinic (BHC) and 114 non-fracture UE fracture patients seen in an UE clinic completed clinic intake surveys assessing for fracture risk factors. Prefracture fracture risk (PFFR) and fracture risk assessment tool (FRAX) scores estimated the future fracture risks at the timepoint before and after the UE fragility fracture event, respectively. The primary study outcome was the 10-year risk of future fracture.

RESULTS

The 10-year probability of major osteoporotic and hip fractures were significantly higher among the BHC group when estimated with FRAX. When estimated with PFFR score, there was no difference in the 10-year probability of hip fracture between the groups. Prevalence of secondary osteoporosis and glucocorticoid use was higher in the BHC group, and prevalence of rheumatoid arthritis was higher in the UE clinic group.

CONCLUSIONS

This study underscores the importance of an UE fragility fracture in determining the risk of future fracture. A fragility fracture of the UE should be considered a sentinel event and physicians who evaluate these patients should recognize them as a high-risk group for future hip fracture.

The Relationship Between Frailty and Functional Outcomes, Range of Motion, and Reoperation After Reverse Total Shoulder Arthroplasty for Proximal Humerus Fracture

The objective of this study was to investigate whether frailty is associated with functional outcomes, motion, and reoperation at a minimum of 2 years after reverse total shoulder arthroplasty (rTSA) for proximal humerus fracture. We performed a retrospective study of 153 patients who underwent rTSA for proximal humerus fracture at two level 1 trauma centers from 2003 to 2018 with minimum 2-year follow-up. Frailty was assessed using the modified 5-item frailty index (mFI). The primary outcome variable was the American Shoulder and Elbow Surgeons (ASES) shoulder score at minimum 2-year follow-up. The secondary outcome variables were the Shoulder Pain and Disability Index (SPADI), the Shoulder Subjective Value (SSV), the 0 to 10 numeric rating scale (NRS) pain score, surgical complication, and reoperation. Bivariate comparisons were made between mFI and outcome variables. The mean age of the 153 patients was 70 years, and 76% were women. Forty patients (26%) had a mFI score of 0, 65 patients (42%) had a mFI score of 1, 40 patients (26%) had a mFI score of 2, and 8 patients (5%) had a mFI score of 3. Twenty-seven patients (18%) had complications, and 21 patients (14%) underwent reoperation. At minimum 2-year follow-up, mFI was not associated with ASES shoulder score, SPADI, SPADI pain or disability subscales, SSV, NRS pain score, active and passive shoulder forward flexion, abduction, and external rotation, complication, or reoperation. Provided they survive the initial physiologic insults of trauma and surgery, patients with higher mFI scores treated with rTSA for proximal humerus fracture can expect similar medium-term restoration of shoulder function.

Factors Associated With 30-Day Morbidity and Mortality Following the Surgical Treatment of Olecranon Fractures

The objective of this study was to identify factors independently associated with complications, hospital readmission, reoperation, and death in the 30-day period after surgical treatment of isolated olecranon fractures. A retrospective case-control study was performed using the National Surgical Quality Improvement Program database by querying the Current Procedural Terminology code for patients who underwent surgical treatment of isolated olecranon fractures from 2011 to 2020. A total of 4404 patients were included. The main study outcomes were 30-day medical or wound complications, hospital readmission, reoperation, and death. A bivariate screen was performed for explanatory variables associated with our outcome variables, and variables with P<.1 in the bivariate screen were included in multivariable regression models. Of the 4404 patients in our cohort, 29 patients (0.7%) developed medical or wound complications, 157 patients (3.6%) were readmitted, 123 patients (2.8%) underwent reoperation, and 12 patients (0.3%) died during the 30-day postoperative period. Multivariable logistic regression analysis showed that older age, smoking, bleeding disorders, and higher American Society of Anesthesiologists classification were associated with readmission; that older age, bleeding disorders, and higher American Society of Anesthesiologists classification were associated with reoperation; and that bleeding disorders were associated with mortality. No identifiable factors were independently associated with medical or wound complications. In this National Surgical Quality Improvement Program database study of olecranon fractures treated surgically during a recent 10-year period, we identified demographic and comorbid factors independently associated with 30-day postoperative readmission, reoperation, and mortality. Our findings are relevant for preoperative risk stratification and counseling. [Orthopedics. 2023;46(5):e310-e316.].

Outcomes After Acute Versus Delayed Total Elbow Arthroplasty for the Treatment of Distal Humerus Fractures

Purpose

Compare outcomes of acute versus delayed total elbow arthroplasty (TEA) following distal humerus fractures (DHF).

Methods

This retrospective study included 39 patients who underwent primary TEA with semiconstrained implants for DHF, either within 4 weeks of their injury or after failing initial open reduction and internal fixation (ORIF) or nonsurgical management, between June 1, 2003 and February 1, 2018 with minimum 1-year follow-up. Our outcome measures included QuickDASH (Disabilities of the Arm, Shoulder, and Hand) score, complications, reoperations, and range of motion (ROM). Demographics, clinical variables, and outcomes were compared using the Student's t-test, Mann-Whitney U test, and Fisher's exact test as appropriate. Kaplan-Meier curves for mortality, implant survivorship, and reoperation were created.

Results

Our patients were categorized into acute TEA (n = 22), ORIF to TEA (n = 10), and nonsurgical to TEA (n = 7) treatment groups. Additional analysis was performed comparing acute to delayed TEA, which combined data from failed ORIF and nonsurgical cohorts. The median follow-up, average age, and median Charlson comorbility index were similar between groups. The most common fracture pattern was AO13C. At median follow-up of 5.8 years, QuickDASH differed between cohorts: mean of 31 (SD 19) in acute TEA and 52 (SD 27) in delayed TEA, which further subdivided to 44.2 (SD 25) in failed ORIF and 76 (SD 23) in failed nonsurgical management. Poorer QuickDASH scores at final follow-up were associated with delayed TEA, initial nonsurgical management, and depression. Surgical complications were associated with delayed TEA. Higher Charlson comorbidity index was associated with death. No variables were associated significantly with ROM, revision, or reoperation.

Conclusion

Comminuted DHFs are difficult to treat in the elderly with high rates of complication and poor function after surgery. Our study suggests TEA performed acutely result in satisfactory outcomes and should be a consideration for patients at high risk of failing ORIF or nonsurgical management.

What Is the Effect of Resident Involvement on Short-Term Outcomes after Distal Radius Fracture Surgery?

Background: The objective of this study was to assess whether resident involvement in distal radius fracture open reduction internal fixation (ORIF) affect 30-day postoperative complication, hospital readmission, reoperation and operative time. Methods: A retrospective study was performed using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database by querying the Current Procedural Terminology (CPT) codes for distal radius fracture ORIF from 1 January 2011 to 31 December 2014. A final cohort of 5,693 adult patients who underwent distal radius fracture ORIF during the study period were included. Baseline patient demographics and comorbidities, intraoperative factors, including operative time and 30-day postoperative outcomes, including complications, readmission and reoperations, were collected. Bivariate statistical analyses were performed to identify variable associated with complication, readmission, reoperation and operative time. The significance level was adjusted using a Bonferroni correction as multiple comparisons were performed. Results: In this study of 5,693 patients who underwent distal radius fracture ORIF, 66 patients had a complication, 85 patients were readmitted and 61 patients underwent reoperation within 30 days of surgery. Resident involvement in the surgery was not associated with 30-day postoperative complication, readmission or reoperation, but was associated with longer operative time. Moreover, 30-day postoperative complication was associated with older age, American Society of Anesthesiologists (ASA) classification, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), hypertension and bleeding disorder. Thirty-day readmission was associated with older age, ASA classification, diabetes mellitus, COPD, hypertension, bleeding disorder and functional status. Thirty-day reoperation was associated with higher body mass index (BMI). Longer operative time was associated with younger age, male sex and the absence of bleeding disorder. Conclusions: Resident involvement in distal radius fracture ORIF is associated with longer operative time, but no difference in rates of episode-of-care adverse events. Patients may be reassured that resident involvement in distal radius fracture ORIF does not negatively impact short-term outcomes. Level of Evidence: Level IV (Therapeutic).

Patient-Perceived Outcomes of Recovery After Trigger Digit Release

PURPOSE

Trigger finger release (TFR) is one of the most commonly performed hand surgeries; nevertheless, the time until patients subjectively feel recovered has not been well documented. The limited literature on patient perceptions of recovery after any type of surgery has described that patients and surgeons may have differing views on the time until full recovery. Our primary study question was to determine how long it takes for patients to subjectively feel fully recovered after TFR.

METHODS

In this prospective study, patients who underwent isolated TFR completed questionnaires before surgery and at multiple time points following surgery until they reported full recovery. Patients completed visual analog scale (VAS) pain scores and QuickDASH (Disabilities of the Arm, Shoulder, and Hand) and were asked if they felt fully recovered at 4 weeks, 6 weeks, and 3, 6, 9, and 12 months.

RESULTS

The average time to self-reported full recovery was 6.2 months (SD 2.6), and the median time to self-reported full recovery was 6 months (IQR 4 months). At 12 months, four out of 50 patients (8%) did not feel fully recovered. QuickDASH and VAS pain scores improved significantly from preoperative assessment to final follow-up. All patients reported improvement in both VAS pain scores and QuickDASH scores greater than the minimal clinically important difference between 6 weeks and 3 months after surgery. Higher preoperative VAS and QuickDASH scores were associated with failure to fully recover by 12 months after surgery.

CONCLUSIONS

The length of time after surgery until patients felt fully recovered after isolated TFR is longer than the senior authors' expectations. This suggests that patients and surgeons may consider distinctly different parameters when discussing recovery. Surgeons should be aware of this discrepancy when discussing recovery after surgery.

Factors Associated With Severity of Cubital Tunnel Syndrome at Presentation

BACKGROUND

The outcomes of cubital tunnel syndrome surgery are affected by preoperative disease severity. The aim of this study was to identify factors associated with clinical and electrodiagnostic severity of cubital tunnel syndrome at presentation.

METHODS

We retrospectively identified 213 patients with electrodiagnostically confirmed cubital tunnel syndrome who underwent cubital tunnel surgery from July 2008 to June 2013. Our primary response variable was clinical cubital tunnel syndrome severity assessed by the McGowan grade. Our secondary response variables were sensory nerve action potential (SNAP) recordability, presence of fibrillations, and motor nerve conduction velocities (CVs) in the abductor digiti minimi (ADM) and first dorsal interosseous (FDI). Bivariate analysis was used to screen for factors associated with disease severity; significant variables were selected for multivariable regression analysis.

RESULTS

Older age was associated with higher McGowan grade and diabetes mellitus was associated with unrecordable SNAPs on bivariate analysis. No other variables met inclusion criteria for multivariable regression analysis for McGowan grade or unrecordable SNAPs. Multivariable regression analysis showed older age and higher Distressed Communities Index (DCI) to be associated with decreased motor nerve CVs in ADM. Multivariable regression analysis showed higher body mass index (BMI) and higher DCI to be associated with decreased motor nerve CVs in FDI. No variable was associated with the presence of fibrillations.

CONCLUSIONS

A subset of patients with cubital tunnel syndrome may benefit from earlier referral for hand surgery evaluation and earlier surgery. Older patients, with higher BMI, with diabetes mellitus, and with economic distress are at higher risk for presentation with more severe disease.

Anatomical Variations of the First Dorsal Compartment in de Quervain Tenosynovitis

BACKGROUND

De Quervain tenosynovitis of the wrist is a common pathology. The primary aim of this study is to determine the prevalence of extensor pollicis brevis and abductor pollicis longus (APL) anatomical variations in association with de Quervain tenosynovitis. The secondary aim was to compare additional patient-specific factors associated with de Quervain tenosynovitis.

METHODS

This retrospective study included 172 patients with de Quervain tenosynovitis who underwent first dorsal compartment release and 179 patients with thumb carpometacarpal (CMC) arthritis who underwent thumb CMC arthroplasty between August 1, 2007, and May 1, 2022. The CMC group was chosen as the control group because the study surgeons perform APL suspensionplasty as the primary procedure for thumb CMC arthritis, allowing for a comparison group without de Quervain tenosynovitis. Exclusion criteria included patients undergoing revision surgery, patients undergoing thumb CMC procedure other than APL suspensionplasty, and patients with both CMC and first dorsal compartment diagnoses. Demographics, clinical variables, and intraoperative findings were collected through retrospective chart reviews.

RESULTS

Patients in the de Quervain tenosynovitis group tended to be younger (51 years, range: 23-92 years vs 63 years, range: 28-85 years), women (86.1% vs 77.1%), and more commonly of African American or black race (15.7% vs 3.9%) and Asian race (5.2% vs 0%). There was a higher prevalence of tendon subcompartments (79.1% vs 64.2%), but fewer number of APL slips (38.3% vs 20.7% 2 or fewer slips) seen in the de Quervain tenosynovitis group.

CONCLUSION

Anatomical variation exists between patients with and without de Quervain tenosynovitis. The presence of tendon subcompartments but not an increased number of tendon slips is associated with de Quervain tenosynovitis.

Perioperative Complications Associated With Limited Surgical Fasciectomy After Collagenase Clostridium Histolyticum for Dupuytren Contracture

BACKGROUND

The purpose of this study was to determine the perioperative complication rate of surgical fasciectomy following previous treatment with collagenase clostridium histolyticum (CCH) treatment in patients with Dupuytren disease.

METHODS

A retrospective review of all patients at a large health system undergoing CCH treatment and subsequent limited surgical fasciectomy for recurrence on the same digit between 2010 and 2020 was performed. Fifty-two patients with 62 affected digits met inclusion criteria, and cases were reviewed for preoperative demographics, treatment characteristics, clinical outcomes, and perioperative complications.

RESULTS

Fifty-five digits in 48 patients were treated with CCH and underwent subsequent limited surgical fasciectomy. Of all digits in the present study, 3 (6.3%) had a documented surgical complication following open surgical fasciectomy. There were zero postoperative infections, vascular injuries, or tendon injuries. The rate of nerve injury was 2.1%. The rate of postoperative skin necrosis was 4.2%. These rates were comparable or lower than those of historical published data.

CONCLUSIONS

The rate of perioperative complications in patients undergoing limited surgical fasciectomy after previous CCH treatment is low. The findings of this study will aid the counseling of Dupuytren patients in deciding whether to pursue treatment with CCH versus open surgical fasciectomy.

Does the Surgical Assistant Influence Perioperative Outcomes Surrounding Cubital Tunnel Surgery?

Background: Ulnar neuropathy at the elbow is the second most common upper extremity compressive neuropathy and surgical treatment often involves surgical trainee involvement. The primary aim of this study is to determine the effect of trainees and surgical assistants on outcomes surrounding cubital tunnel surgery. Methods: This retrospective study included 274 patients with cubital tunnel syndrome who underwent primary cubital tunnel surgery at two academic medical centres between 1 June 2015 and 1 March 2020. The patients were divided into four main cohorts based on primary surgical assistant: physician associates (PA, n = 38), orthopaedic or plastic surgery residents (n = 91), hand surgery fellows (n = 132), or both residents and fellows (n = 13). Exclusion criteria included patient age <18 years, revision surgery as the index procedure, prior traumatic ulnar nerve injury and concurrent procedures not related to cubital tunnel surgery. Demographics, clinical variables and perioperative findings were collected through chart reviews. Univariate and bivariate analyses were performed, and p < 0.05 was considered significant. Results: Patients in all cohorts had similar demographic and clinical characteristics. There was a significantly higher rate of subcutaneous transposition in the PA cohort (39.5% PA vs. 13.2% Resident vs. 19.7% Fellow vs. 15.4% Resident + Fellow). Presence of surgical assistants and trainees had no association with length of surgery, complications and reoperation rates. Although male sex and ulnar nerve transposition were associated with longer operative times, no explanatory variables were associated with complications or reoperation rates. Conclusions: Surgical trainee involvement in cubital tunnel surgery is safe and has no effect on operative time, complications or reoperation rates. Understanding the role of trainees and measuring the effect of graduated responsibility in surgery is important for medical training and safe patient care. Level of Evidence: Level III (Therapeutic).

The Environmental Impact of Open Versus Endoscopic Carpal Tunnel Release

PURPOSE

The environmental impact of common ambulatory hand surgeries has been an area of growing interest in recent years. There were 2 objectives of this study: (1) to quantify the carbon footprint of carpal tunnel surgery and its principal driving components; and (2) to compare the carbon footprints of open carpal tunnel release (oCTR) and endoscopic carpal tunnel release (eCTR).

METHODS

We performed a life cycle assessment to quantify the environmental impacts of 2 surgical procedures: oCTR and eCTR. Patients were retrospectively identified by querying the Mass General Brigham institutional billing database. Fourteen oCTR procedures and 14 eCTR procedures in 28 patients were included in the life cycle assessment. The boundaries of the life cycle assessment were the start and end times of the procedures. The environmental impacts were estimated using the carbon footprint, expressed in the equivalent mass of carbon dioxide released into the atmosphere (kgCO₂-eq). The facility-related, processing-related, solid waste-related, and total kgCO₂-eq were calculated.

RESULTS

The average carbon footprint of carpal tunnel release was 83.1 kgCO₂-eq and was dominated by processing-related and facilities-related factors. The average carbon footprint of eCTR (106.5 kgCO₂-eq) was significantly greater than that of oCTR (59.6 kgCO₂-eq).

CONCLUSIONS

Endoscopic carpal tunnel release leaves a greater carbon footprint than oCTR, and its environmental impact is dominated by facility-related and central processing-related factors.

Patterns and Persistence of Perioperative Plasma and Cerebrospinal Fluid Neuroinflammatory Protein Biomarkers After Elective Orthopedic Surgery Using SOMAscan

BACKGROUND

The neuroinflammatory response to surgery can be characterized by peripheral acute plasma protein changes in blood, but corresponding, persisting alterations in cerebrospinal fluid (CSF) proteins remain mostly unknown. Using the SOMAscan assay, we define acute and longer-term proteome changes associated with surgery in plasma and CSF. We hypothesized that biological pathways identified by these proteins would be in the categories of neuroinflammation and neuronal function and define neuroinflammatory proteome changes associated with surgery in older patients.

METHODS

SOMAscan analyzed 1305 proteins in blood plasma (n = 14) and CSF (n = 15) samples from older patients enrolled in the Role of Inflammation after Surgery for Elders (RISE) study undergoing elective hip and knee replacement surgery with spinal anesthesia. Systems biology analysis identified biological pathways enriched among the surgery-associated differentially expressed proteins in plasma and CSF.

RESULTS

Comparison of postoperative day 1 (POD1) to preoperative (PREOP) plasma protein levels identified 343 proteins with postsurgical changes ( P < .05; absolute value of the fold change [|FC|] > 1.2). Comparing postoperative 1-month (PO1MO) plasma and CSF with PREOP identified 67 proteins in plasma and 79 proteins in CSF with altered levels ( P < .05; |FC| > 1.2). In plasma, 21 proteins, primarily linked to immune response and inflammation, were similarly changed at POD1 and PO1MO. Comparison of plasma to CSF at PO1MO identified 8 shared proteins. Comparison of plasma at POD1 to CSF at PO1MO identified a larger number, 15 proteins in common, most of which are regulated by interleukin-6 (IL-6) or transforming growth factor beta-1 (TGFB1) and linked to the inflammatory response. Of the 79 CSF PO1MO-specific proteins, many are involved in neuronal function and neuroinflammation.

CONCLUSIONS

SOMAscan can characterize both short- and long-term surgery-induced protein alterations in plasma and CSF. Acute plasma protein changes at POD1 parallel changes in PO1MO CSF and suggest 15 potential biomarkers for longer-term neuroinflammation that warrant further investigation.

Pronator Quadratus Repair Does Not Affect Reoperation Rates Following Volar Locking Plate Fixation of Distal Radius Fractures

BACKGROUND

The purpose of this study was to evaluate the impact of pronator quadratus (PQ) repair on reoperation rates after distal radius open reduction internal fixation (ORIF) using a volar locking plate.

METHODS

A retrospective study of all patients undergoing distal radius ORIF with a volar locking plate between January 2012 and December 2016 at 2 urban, academic level I trauma centers was performed. Patient demographics, fracture and procedure characteristics, surgeon subspecialty, PQ repair, and reoperations were recorded. Descriptive statistics were used to determine whether patient-related or injury-related characteristics were associated with PQ repair. Bivariate and multivariable regression analyses were used to assess the effect of PQ repair on subsequent reoperations.

RESULTS

In total, 509 patients were included, including 31 patients with bilateral injuries. The average follow-up time was 3.7 ± 2.8 years. Patients undergoing PQ repair were younger (57 ± 17 years vs 61 ± 17 years) and were more likely to have a lower Soong grade (53% vs 44% with Soong grade 0) than patients without PQ repair. Pronator quadratus repair was not found to have a significant impact on hardware removal, reoperations for flexor tendon pathology, or overall reoperations.

CONCLUSIONS

Pronator quadratus repair was more commonly performed in younger patients and in patients with a lower Soong grade. Hand-subspecialized surgeons are more likely to pursue PQ repair than trauma-subspecialized surgeons. This study did not detect statistically significant differences in hardware removal, flexor tendon pathology, or overall reoperations between groups.

Association of Economic Well-Being With Comorbid Conditions in Patients Undergoing Carpal Tunnel Release

PURPOSE

Medical comorbidities have been associated with the development of carpal tunnel syndrome (CTS), severity at the time of presentation, and outcomes of carpal tunnel release (CTR). Socioeconomic factors have also been associated with worse function in patients with CTS at presentation and after surgery. However, the effects of economic well-being on the prevalence of medical comorbidities in patients with CTS have not been well-described. The objective of this study was to determine whether economic well-being is associated with medical comorbidities in a cohort of patients undergoing CTR.

METHODS

Patients (n = 1,297) who underwent CTR at a single tertiary care referral center over a 5-year period from July 2008 to June 2013 were retrospectively identified. The exclusion criteria were acute trauma or infection, revision surgery, incomplete medical records, and neoplasm excision. Additionally, patients were excluded if they lacked documented confirmatory or normal electrodiagnostic study findings prior to CTR. Finally, this study comprised a cohort of 892 patients with electrodiagnostic study-confirmed CTS who underwent CTR. The economic well-being of patients was assessed using the Distressed Communities Index. The comorbidities of diabetes mellitus, chronic kidney disease, hypertension, hypothyroidism, cervical radiculopathy, tobacco use, and body mass index were assessed. Bivariate comparisons were used to determine the associations between the tiers of economic well-being and comorbidities.

RESULTS

Lower economic well-being was associated with body mass index, diabetes mellitus, chronic kidney disease, and tobacco use in these patients. Although hypertension, hypothyroidism, and cervical radiculopathy were not associated with economic well-being, their comparisons were underpowered.

CONCLUSIONS

Patients experiencing economic distress have a higher comorbidity burden, and as such, may be at an increased risk of complications or poorer outcomes. The association between economic well-being and comorbidities in this population suggests the need for a multidisciplinary care model that addresses both compressive neuropathy and the associated economic factors.

Implicit and Explicit Factors That Influence Surgeons' Decision-Making for Distal Radius Fractures in Older Patients

PURPOSE

The purpose of this study was to evaluate factors that influence surgeons' decision-making in the treatment of distal radius fractures in older patients.

METHODS

Fourteen clinical vignettes of a 72-year-old patient with a distal radius fracture were sent to 185 orthopedic hand and/or trauma surgeons. The surgeons were surveyed regarding the demographic/practice details, treatment decision (surgical or nonsurgical), and factors that influenced management, including the Charlson Comorbidity Index, functional status, radiographic appearance, and handedness. Multivariable regression analyses were used to assess the effect of both surgeon-described (explicit) and given clinical (implicit) factors on the treatment decision and to evaluate for discrepancies.

RESULTS

Sixty-six surgeons completed the survey, and 7 surgeons completed 10-13 vignettes. Surgeons made the explicit determination to pursue nonsurgical treatment based on the presence of comorbidities (odds ratio [OR], 0.02 for surgery; 95% confidence interval [CI], 0.01-0.05), but the observation of the underlying clinical data suggested that the recommendation for surgical treatment was instead based on a higher functional status (OR, 3.54/increase in functional status; 95% CI, 2.52-4.98). Those employed by hospitals/health systems were significantly less likely to recommend surgery than those in private practice (OR, 0.42; 95% CI, 0.23-0.79) CONCLUSIONS: This study demonstrates that the presence of comorbidities, functional status, and practice setting has a significant impact on a surgeon's decision to treat distal radius fractures in older patients. The discrepancy between the surgeon-described factors and underlying clinical data demonstrates cognitive bias.

CLINICAL RELEVANCE

Surgeons should be aware of cognitive biases in clinical reasoning and should work through consequential patient decisions using an analytical framework that attempts to reconcile all available clinical data.

Risk Factors for Implant Removal After Surgical Fixation of Midshaft Clavicle Fractures

Midshaft clavicle fractures are common injuries that traditionally have been managed nonoperatively. However, recent literature has shown lower rates of nonunion and improved patient-reported outcomes with surgical management. The rate of implant removal after surgical fixation varies across the literature from 5% to 82%, depending on the method of fixation. We performed a retrospective review of all patients who underwent open reduction and internal fixation (ORIF) with plate-and-screw constructs for midshaft fractures of the clavicle at 2 level I trauma centers to determine the rate of implant removal and identify variables associated with implant removal. We collected all patient-, injury-, and treatment-specific factors as well as information on reoperation for removal of implants. Bivariate analysis and multivariable logistic regression analysis were used to assess whether explanatory factors were associated with removal of implants after ORIF for midshaft clavicle fractures. Of the 146 patients who were treated with ORIF for midshaft clavicle fractures with plate-and-screw constructs, 41 (28%) underwent removal of the implant. The median follow-up was 836 days (interquartile range, 457-1567 days). Variables associated with increased risk of implant removal included anterior plate position (odds ratio, 5.32; 95% CI, 2.01-14.1) and number of holes in the plate (odds ratio, 1.28; 95% CI, 1.00-1.63). These results question whether anterior plating results in less implant prominence and less subsequent removal of implants. [Orthopedics. 2022;45(4):e201-e206.].

Radiographic Outcomes and Complications of Delayed Fixation of Distal Radius Fractures

BACKGROUND

Surgeons are sometimes presented with patients with distal radius fractures who present in a delayed fashion or lose reduction after several weeks of attempted closed management. There are limited studies on delayed surgical treatment of distal radius fractures to assist providers in decision-making.

METHODS

We conducted a matched cohort study to compare radiographic outcomes and complications for patients with a distal radius fracture treated with delayed (3-5 weeks) or early (0-2 weeks) surgical fixation. Patients ages 18+ who underwent open reduction and internal fixation of distal radius fractures by a volar approach at 2 Level I trauma centers between 2003 and 2015 were eligible. We measured radiographic outcomes and reviewed medical records to determine operative approach and complications.

RESULTS

There were 25 cases and 50 controls matched for age (18-87), sex, and AO fracture type. The delayed group had surgery at a mean of 24.8 days from injury and the early group at 5.6 days. There was no statistically significant difference between the delayed and early cohorts in radiographic parameters on injury x-rays, in improvement in radiographic parameters on first postoperative x-rays, or in maintenance of radiographic parameters at union.

CONCLUSION

We did not find significant differences in radiographic outcomes or complication rates between patients with delayed versus early surgical treatment for distal radius fracture. Providers treating patients with late presentation or late displacement have the option of surgical fixation beyond the first few weeks after injury.

The Impact of the Soong Index on Hardware Removal and Overall Reoperation Rates After Volar Locking Plate Fixation of Distal Radius Fractures

PURPOSE

This study sought to determine the impact of volar plate prominence on reoperation rates after open reduction and internal fixation of distal radius fractures with volar locking plates and to identify other factors associated with removal of hardware (ROH) or a reoperation.

METHODS

A retrospective study of patients who underwent distal radius open reduction and internal fixation between 2012 and 2016 at 2 level I trauma centers was conducted. Plate prominence was evaluated using the Soong index at the first postoperative visit. The details of patient demographics, fracture and plate characteristics, complications, and reoperations were recorded. Bivariate and multivariable regression analyses were used to identify factors associated with increased rates of ROH and overall reoperation.

RESULTS

A total of 732 (70.2%) of 1,042 patients completed follow-up at an average of 38.2 months, including 34 patients with bilateral operations, yielding 766 distal radius fractures. One hundred sixteen (15.1%) patients underwent reoperation at an average of 12.1 ± 13.6 months after the index surgery. Removal of hardware was the most commonly performed reoperation (77 patients, 10%). The multivariable regression analysis revealed significantly higher rates of ROH in Soong grade 1 or 2 patients (odds ratio 16, 95% CI 5.8-47; odds ratio 44, 95% CI 14-140, respectively) than in Soong grade 0 patients. Plate type, younger age, bilateral injuries, and concomitant procedures at the time of the index operation were all associated with increased risk of ROH. There were significant differences between individual surgeons the in rates of ROH (range 2.1%-22%) and overall reoperation (range 5.2%-36%). Compared with other hand surgeons, fellowship-trained hand surgeons had lower rates of ROH (8% vs 14%, respectively) and overall reoperation (12% vs 22%, respectively).

CONCLUSIONS

The rates of ROH and overall reoperation increase with increasing Soong grade. Plate type is independently predictive of future ROH. Older patients and those undergoing open reduction and internal fixation experience lower rates of subsequent reoperation.

Gender Disparity Trends in Authorship of Hand Surgery Research

PURPOSE

Despite an overall trend towards gender parity, women continue to remain underrepresented in surgical fields. Until recently, women's representation in hand surgery literature was largely unexplored. The objective of this study was to examine how authorship gender trends among academic hand surgeons have evolved between 2006 and 2019.

METHODS

Original research articles published from 2006 to 2019 in 3 leading clinical hand surgery journals were extracted from PubMed. Publications with a full author first name were analyzed, and the gender of each author was assigned with the validated Genderize algorithm. Analyses were performed to evaluate authorship publication trends, unique authors, and research career productivity.

RESULTS

From 2006 to 2019, 4,769 articles met the inclusion criteria, and the genders of 17,102 authors were identified. There were 2,848 (16.6%) female authors and 14,254 (83.4%) male authors. The proportion of female authors increased from 13.4% to 19.9% from 2006 to 2019. Similarly, female representation as first and senior authors increased significantly, from 10.9% to 20.1% and 7.6% to 14.2%, respectively. Of the 8,417 unique authors, 1,775 (21.1%) were women and 6,642 (78.9%) were men. Only 3.3% of these unique female authors published 5 or more papers during the study period. Among the 10 most frequently published authors for each gender, 18 of the 20 authors were surgeons.

CONCLUSIONS

There has been substantial progress toward gender parity in academic hand surgery over the last 14 years, and the proportion of women publishing in leadership positions has increased.

CLINICAL RELEVANCE

Increased gender representation in medicine and research is important for both patients and providers, and these findings suggest that ongoing support and mentorship for women in academic careers should be a priority.

Patient Preferences for Limited Fasciectomy Versus Collagenase Treatment for Dupuytren Contracture

Background: The primary objective of this study was to assess patient preferences for collagenase Clostridium histolyticum (CCH) treatment versus limited surgical fasciectomy in a cohort that has undergone both treatments for Dupuytren contracture. Methods: We retrospectively identified 68 patients who have undergone both limited surgical fasciectomy and CCH treatment for digital flexion contractures from Dupuytren disease. Patients were contacted by telephone and asked whether they preferred surgery or CCH treatment for their Dupuytren contracture. Multivariable logistic regression was used to determine factors associated with preference for surgery versus CCH treatment. Results: Of the 68 patients who were treated with both CCH and surgery, 37 patients (54.4%) preferred CCH treatment over surgery, 26 (38.2%) preferred surgery over CCH treatment, and 5 (7.4%) were unable to decide. Patients expressed common themes of the perceived ease of recovery following CCH treatment versus the perceived durability of contracture correction with surgery. Preference for surgical fasciectomy over CCH treatment was associated with lower American Society of Anesthesiologists Physical Status Classification (ASA) [odds ratio (OR): 0.32, 95% confidence interval (CI): 0.14-0.75]. The order of treatment was also associated with the treatment preference; treatment with surgery after CCH compared to treatment with CCH after surgery was associated with a preference for surgery (OR: 6.51, 95% CI: 2.15-19.7). Conclusions: In a cohort of patients who have undergone both treatments, patients were divided in their preferences, with a slight majority preferring CCH treatment over surgery. Treatment recommendations should be individualised to each patient's long-term goals and expectations. Level of Evidence: Level III (Therapeutic).

Factors Associated With Implant Removal Following Plate-and-Screw Fixation of Isolated Metacarpal Fractures

PURPOSE

The incidence of and associated risk factors for implant removal following the plate-and-screw fixation of metacarpal shaft fractures have not been well described. The primary objective of our study was to identify implant-related radiographic parameters associated with implant removal in patients treated with the plate-and-screw fixation of isolated, displaced metacarpal fractures at 2 years of follow-up. The secondary objective of our study was to identify patient-related factors associated with implant removal.

METHODS

A retrospective study of all patients who underwent open treatment of a metacarpal fracture with a plate-and-screw construct from January 1, 2000, to April 30, 2019, at 2 level-1 trauma centers was conducted. After the application of exclusion criteria, we identified 138 patients with a single isolated metacarpal fracture of a nonthumb digit treated with open reduction and internal fixation using a plate-and-screw construct. Our study endpoint was the removal of the plate-and-screw construct or a minimum of 2 years of follow-up without the removal of the hardware. Twenty-three patients achieved our study endpoint as determined using their electronic medical records, and 58 additional patients were reached via telephone to confirm their implant removal status. A bivariate analysis was used to screen for factors associated with implant removal, and variables significant in the bivariate screen were included in a multivariable stepwise logistic regression model.

RESULTS

Twenty-three out of 81 patients (28%) in our final cohort underwent implant removal by the final follow-up visit. In the logistic regression analysis, the distance between the plate and metacarpophalangeal joint, the distance between the plate and carpometacarpal joint, and active smoking were independently associated with implant removal.

CONCLUSIONS

The proximity of metacarpal plates to adjacent joints is associated with subsequent implant removal. Patients may be counseled about the higher risk of implant removal when periarticular metacarpal plating is performed.

SLAMF7 engagement superactivates macrophages in acute and chronic inflammation

Macrophages regulate protective immune responses to infectious microbes, but aberrant macrophage activation frequently drives pathological inflammation. To identify regulators of vigorous macrophage activation, we analyzed RNA-seq data from synovial macrophages and identified SLAMF7 as a receptor associated with a superactivated macrophage state in rheumatoid arthritis. We implicated IFN-γ as a key regulator of SLAMF7 expression and engaging SLAMF7 drove a strong wave of inflammatory cytokine expression. Induction of TNF-α after SLAMF7 engagement amplified inflammation through an autocrine signaling loop. We observed SLAMF7-induced gene programs not only in macrophages from rheumatoid arthritis patients but also in gut macrophages from patients with active Crohn's disease and in lung macrophages from patients with severe COVID-19. This suggests a central role for SLAMF7 in macrophage superactivation with broad implications in human disease pathology.

Minimum 2-year outcomes of reverse total shoulder arthroplasty for fracture: how does acute arthroplasty compare with salvage?

BACKGROUND

The objective of our study was to compare patient-reported outcome measures, range of motion (ROM), complication rates, and reoperation rates after reverse total shoulder arthroplasty (rTSA) for proximal humeral fractures between patients treated acutely (≤30 days after injury), those treated after initial nonoperative treatment (>30 days after injury), and those treated after failed open reduction-internal fixation. Secondarily, we aimed to identify any patient-, injury-, or surgery-related factors independently associated with our response variables.

METHODS

We identified 576 patients who sustained a proximal humeral fracture treated with primary or revision shoulder arthroplasty between January 2003 and August 2018. The final cohort included 153 patients. Multivariable analysis was used to assess whether explanatory variables were associated with our response variables.

RESULTS

Initial nonoperative treatment compared with acute rTSA was associated with worse Shoulder Subjective Value (P = .04), Shoulder Pain and Disability Index score (P = .03), and Shoulder Pain and Disability Index disability subscale score (P = .03). Only depression was independently associated with worse visual analog scale pain score (P = .04). There was no significant difference in postoperative ROM between the initial treatment groups. Older age was associated with decreased ROM in all planes. Additionally, ipsilateral upper-extremity injury was associated with decreased active abduction (P = .03), and cemented humeral stems were associated with decreased passive abduction (P = .03). Initial nonoperative treatment was associated with increased complication rates (odds ratio, 3.65; 95% confidence interval, 1.11-12.01), and male sex was associated with higher rates of reoperation (odds ratio, 3.53; 95% confidence interval, 1.31-9.51).

CONCLUSIONS

Patients who undergo initial periods of nonoperative management have worse functional outcomes and higher complication rates than those who undergo acute rTSA for proximal humeral fractures. Patients who undergo rTSA after failed open reduction-internal fixation show no difference in patient-reported outcomes compared with those who undergo acute rTSA. In addition, male patients are at higher risk of reoperation, whereas older patients are at risk of decreased ROM. Patients with preoperative depression are at risk of increased pain at 2 years after surgery.

Readability of Online Hand Surgery Patient Educational Materials: Evaluating the Trend Since 2008

PURPOSE

Online patient educational materials have historically been written at a higher-than-recommended sixth grade reading level. The objectives of this study were to assess the readability of online hand surgery patient educational materials from the official online patient resource website of the American Society for Surgery of the Hand (ASSH) and to compare changes in the readability of the current ASSH online patient educational materials with those in 2008 and 2015.

METHODS

An internet-based study of all 88 English language patient educational materials on HandCare.org, the official online patient resource website of the ASSH, was performed. The readability of each article was assessed using the Flesch reading ease formula, Flesch-Kincaid grade level, Coleman-Liau index, Gunning-Fog index, and Simple Measure of Gobbledygook grade level. To evaluate the trend in the readability of ASSH online hand surgery patient educational materials, the Flesch-Kincaid grade levels of articles published in 2020 were compared with those of data published in 2008 and 2015.

RESULTS

The average Flesch reading ease score of the patient educational materials was 57.6, which is at the high-school reading level. The average reading grade level of patient educational materials ranged from 9.0 to 12.3 depending on the readability metric used. The average Flesch-Kincaid grade level of all the ASSH patient educational materials was 9.8 in 2020, which is significantly better than 10.4 in 2008 but significantly worse than 8.5 in 2015.

CONCLUSIONS

Online hand surgery patient educational materials continue to be written for the general public at a higher-than-recommended reading grade level. There has been no substantial improvement in the readability of online hand surgery patient educational materials since 2008.

CLINICAL RELEVANCE

Improvements are needed in the readability of online patient educational materials to ensure that patients with all health literacy levels are able to comprehend and benefit from health information.

Longitudinal Changes in Serum Markers of Bone Metabolism and Bone Material Strength in Premenopausal Women with Distal Radial Fracture

BACKGROUND

Markers of bone metabolism (MBM) play an important role in fracture evaluation, and changes have been associated with increased fracture risk. The purpose of the present study was to describe changes in MBM in premenopausal women with distal radial fractures.

METHODS

Premenopausal women with distal radial fractures (n = 34) and without fractures (controls) (n = 39) were recruited. Serum MBM in patients with distal radial fractures were obtained at the time of the initial presentation, 6 weeks, and 3, 6, and 12 months. MBM included 25(OH) vitamin D, PTH, osteocalcin, P1NP, BSAP, CTX, sclerostin, DKK1, periostin, and TRAP5b. Areal bone mineral density (aBMD) was assessed with dual x-ray absorptiometry, and the bone material strength index (BMSi) was assessed with microindentation.

RESULTS

Most MBM reached peak levels at 6 weeks after the injury, including osteocalcin (+17.7%), sclerostin (+23.5%), and DKK1 (12.6%). Sclerostin was lower (-27.4%) and DKK1 was higher (+22.2%) at 1 year after the fracture. CTX declined below baseline levels at 6 and 12 months, whereas TRAP5b, BSAP, and periostin did not significantly change. At 12 months, sclerostin was lower (p = 0.003) and DKK1 was higher (p = 0.03) in the distal radial fracture group than in the control group. Greater fracture severity was associated with greater increases in P1NP and BSAP. aBMD and BMSi were not associated with fracture.

CONCLUSIONS

Distal radial fractures caused increases in several MBM, which typically peaked at 6 weeks after injury and gradually decreased over 6 months. Sclerostin and DKK1 remained below and above baseline at 1 year, respectively. Increasing fracture severity resulted in larger changes in MBM. aBMD and BMSi did not discriminate between patients with distal radial fractures and controls. Continued efforts to identify markers of skeletal fragility in young women are warranted to mitigate future fracture risk.

Subspecialty Variation in Academic Citations of Orthopedic Surgery Publications

Background

The objective of this study was to assess the variation in academic citation and social media mentions across orthopedic subspecialties in general orthopedic surgery journals.

Methods

An internet-based study was performed of 666 articles from four orthopedic journals published from January 2018 to February 2019. Each publication was categorized by its subspecialty within orthopedics: arthroplasty, hand and upper extremity, foot and ankle, orthopedic oncology, pediatric orthopedics, shoulder, spine, sports medicine, orthopedic trauma, basic science, and miscellaneous. For each publication, academic citations were quantified using Google Scholar and Web of Science, and social media mentions were quantified using Twitter. Comparisons of continuous data among various subspecialties were performed using analysis of variance.

Results

The average number of citations per publication was 7.4 ± 9.0 on Google Scholar, 4.5 ± 5.3 on Web of Science, and 2.8 ± 8.7 on Twitter. The number of academic citations differed significantly by subspecialty on Google Scholar (p < 0.001) and Web of Science (p < 0.001). There was no difference in social media mentions on Twitter by subspecialty (p = 0.8). The most highly cited subspecialties, adjusted for number of publications, were arthroplasty, orthopedic oncology, and sports medicine, while the least highly cited subspecialties were hand and upper extremity, pediatric orthopedics, and orthopedic basic science.

Conclusions

There is significant baseline variation in the citation of orthopedic publications among various subspecialties. Our findings argue against the use of a uniform threshold to gauge scholarly success in orthopedic surgery. The variation in citation of orthopedic publications across subspecialties support the use of subspecialty-specific benchmarks to gauge academic productivity.

Correlation Between Social Media Postings and Academic Citations of Hand Surgery Research Publications

PURPOSE

The relationship between social media postings and academic citations of hand surgery research publications is not known. The objectives of this study were (1) to quantify adoption of social media for the dissemination of original research publications by 3 hand surgery journals, and (2) to determine the correlation between social media postings and academic citations in recent hand surgery research publications.

METHODS

An Internet-based study was performed of all research articles from 3 hand surgery journals published from January 2018 to March 2019. A final sample of 472 original full-length scientific research articles was included. For each article, the total number of social media postings was determined using Twitter, as well as the number of tweets, number of retweets, number of tweets from an official outlet, and number of tweets from an author. The number of academic citations for each article was determined using Google Scholar.

RESULTS

Average number of academic citations per article was 3.9. Average number of social media posts per article was 3.2, which consisted of an average of 1.3 tweets and 1.9 retweets per article. The number of academic citations per article was weakly correlated with the number of social medial postings, the number of tweets, and the number of retweets. The number of tweets from an official outlet and from an author were weakly correlated with academic citation.

CONCLUSIONS

In the early adoption of social media for the dissemination of hand surgery research, there is a weak correlation between social media posting of hand surgery research and academic citation.

CLINICAL RELEVANCE

Future studies are needed to assess whether social media posting of hand surgery research results in academic citations at the longer time intervals necessary for research publication maturity.

The Impact Of COVID-19 Restrictions on an Academic Hand Surgery Practice

Purpose

The impact of the severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019) has been felt worldwide. We examined the quantitative impact during the first 4 weeks of hospital system and state-mandated restrictions on an academic, urban hand surgery practice. We hypothesized that the volume of clinic encounters, office procedures, and surgical cases would decrease and that the volume of nonelective care would remain unchanged.

Methods

We retrospectively reviewed all encounters at a hand surgery practice from March 16, 2020, through April 12, 2020 and compared those to two 4-week control time periods. Weekly encounter volumes and work relative value units (RVUs) were obtained for clinic encounters, office procedures, and surgical cases. The type of ambulatory visit was also identified. Surgical cases were categorized into 4 types (fracture or dislocation, acute soft tissue or nerve injury, infection, or elective/nonurgent) for the most recent time periods. We performed t tests to compare weekly volumes and RVUs between time periods.

Results

After the implementation of mandated restrictions on elective health care, ambulatory hand surgery clinic encounters decreased 72% to 73%, clinic procedures decreased by 87% to 90%, and surgical cases decreased by 87% to 88%. The percentage of ambulatory visits performed via telemedicine increased from 0.06% to 74%. Similar impacts on RVUs were seen. Surgeries for fractures and dislocations declined by 58% and those for acute soft tissue or nerve injury declined by 40%; the number of surgical procedures for infection remained unchanged.

Conclusions

The coronavirus restrictions on elective healthcare led to an immediate, substantial impact on hand surgery practice. There were significant decreases in the volumes of ambulatory encounters, office procedures, and surgical cases. The long-term financial impact of this change in practice is still to be determined but, based on the quantitative impacts seen, is likely to be significant.

Dupuytren's Contracture: The Readability of Online Information

Dupuytren's contracture is a common hand pathology for which consultation and treatment are largely at the patient's discretion. The objective of this study was to evaluate the readability of current online patient information regarding Dupuytren's contracture. The largest public search engines (Google, Yahoo, and Bing) were queried using the search terms “Dupuytren's contracture,” “Dupuytren's disease,” “Viking's disease,” and “bent finger.” The first 30 unique websites by each search were analyzed and readability assessed using five established algorithms: Flesch Reading Ease, Gunning-Fog Index, Flesch–Kincaid Grade level, Coleman–Liau index, and Simple Measure of Gobbledygook grade level. Analysis of 73 websites demonstrated an average Flesch Reading Ease score of 48.6 ± 8.0, which corresponds to college reading level. The readability of websites ranged from 10.5 to 13.3 reading grade level. No article was written at or below the recommended sixth grade reading level. Information on the internet on Dupuytren's contracture is written at higher than recommended reading grade level. There is a need for high-quality patient information on Dupuytren's contracture at appropriate reading grade levels for patients of various health literacy backgrounds. Hospitals, universities, and academic organizations focused on the development of readable online information should consider patients’ input and preferences.

Long-term Effects of Skin Tearing on Outcomes After Collagenase Treatment of Dupuytren Contractures

Background: The objective of this study was to compare the rates of recurrence, additional treatment, patient satisfaction, and willingness to undergo Clostridium histolyticum (CCH) treatment again for Dupuytren disease in patients with and without skin tearing at minimum 5-year follow-up. Methods: We identified 199 digits in 142 patients who underwent CCH treatments for Dupuytren disease from April 2010 to December 2013 with minimum 5-year follow-up. Patients were contacted by telephone to collect our response variables: perceived recurrence of contracture, additional treatment, satisfaction, and willingness to undergo CCH treatment again. Medical records were reviewed for skin tearing at manipulation and patient-related and disease-specific variables. Results: At the time of manipulation, 16 out of 142 patients (11%) and 22 out of 199 digits (11%) had skin tearing. Older age was associated with skin tearing. At an average 7.2-year follow-up, the mean satisfaction was 7.1 ± 2.6 on a 1 to 10 Likert scale for patients with skin tearing and 6.5 ± 3.4 for patients without skin tearing. Eighty-one percent of patients with skin tearing expressed willingness to undergo CCH treatment again, compared with 68% of patients without skin tearing. Perceived recurrence of contracture occurred in 82% of digits with skin tearing and 80% of digits without skin tearing. Additional treatment was performed in 45% of digits with skin tearing and 54% of digits without skin tearing. No difference was statistically significant. Conclusions: Although skin tearing at CCH manipulation complicates the short-term course following CCH treatment, it does not affect long-term perceived contracture recurrence or patient satisfaction.

Shoulder Arthrodesis versus Upper Trapezius Transfer for Traumatic Brachial Plexus Injury: A Proportional Meta-Analysis

Shoulder arthrodesis and upper trapezius transfer are two surgical options for secondary shoulder reconstruction for traumatic brachial plexus injury (BPI). There is a lack of comparative evidence to guide the choice for one procedure over the other. The objectives of this study were to compare (1) rates of complications and reoperation and (2) shoulder range of motion and functional outcome scores following shoulder arthrodesis versus upper trapezius transfer for traumatic BPI. A systematic review and meta-analysis were conducted by a search of four databases of studies assessing shoulder arthrodesis and/or upper trapezius transfer for shoulder reconstruction following adult traumatic BPI. A proportional meta-analysis was performed using a random effects model in anticipation of unobserved heterogeneity. The final meta-analysis included 374 patients from 17 studies, including 232 patients from 11 studies on shoulder arthrodesis and 142 patients from 6 studies on upper trapezius transfer. Shoulder arthrodesis had higher rates of complications and reoperations than upper trapezius transfer for traumatic BPI, but these differences did not reach a statistical significance. Due to the limited sample size, variations in reporting, and study heterogeneity in the published literature, we were not able to draw conclusions regarding shoulder range of motion and functional outcome scores between these two procedures. Shoulder arthrodesis and upper trapezius transfer are both viable options for secondary shoulder reconstruction for traumatic BPI, but with different complications and reoperation profiles. Patients should be counseled on the risk of nonunion and humerus fracture following shoulder arthrodesis.

Factors Associated With Surgical Treatment of Isolated, Displaced Midshaft Clavicle Fractures

Given the current available evidence, surgical treatment of isolated, displaced midshaft clavicle fractures is discretionary. The aim of this study was to determine whether there are identifiable factors associated with the surgical treatment of isolated, displaced midshaft clavicle fractures. A retrospective cohort study of 150 patients who underwent nonoperative treatment and 290 patients who underwent surgical treatment of isolated, displaced midshaft clavicle fractures from January 2010 to March 2019 at 2 level I trauma centers was performed. Multivariable regression analysis demonstrated that younger age (odds ratio [OR], 0.97; 95% CI, 0.95-0.99), absence of diabetes mellitus (OR, 0.045; 95% CI, 0.003-0.79), nonsmoking status (OR, 0.31; 95% CI, 0.13-0.75), higher American Society of Anesthesiologists classification (OR, 5.0; 95% CI, 2.7-9.2), fracture comminution (OR, 2.3; 95% CI, 1.3-3.9), and fracture displacement (OR, 1.1; 95% CI, 1.0-1.1) were associated with surgical treatment of an isolated, displaced midshaft clavicle fracture. Furthermore, lower social deprivation (OR, 0.99; 95% CI, 0.97-0.99) and private insurance compared with Medicare (OR, 6.6; 95% CI, 1.6-27) were associated with surgical treatment. The authors conclude that surgical treatment of discretionary midshaft clavicle fractures is influenced by patient factors, fracture characteristics, and socioeconomic factors. Further study is needed to understand the etiology of social disparities in clavicle surgery and rectify unintended trends in treatment. [Orthopedics. 2021;44(4):e515-e520.].

Limited Fasciectomy Versus Collagenase Clostridium histolyticum for Dupuytren Contracture: A Propensity Score Matched Study of Single Digit Treatment With Minimum 5 Years of Telephone Follow-Up

PURPOSE

The purpose of this study was to compare reintervention and perceived recurrence, with minimum 5 years of telephone follow-up, after limited fasciectomy or collagenase Clostridium histolyticum (CCH) in the treatment of Dupuytren contracture affecting a single digit.

METHODS

We performed a retrospective cohort study of 48 patients with single digit treatment who underwent limited surgical fasciectomy at one hospital and 111 patients who underwent CCH treatment at a second hospital from 2010 to 2013. Patients were contacted by telephone about reintervention and perceived recurrence. Average length of telephone follow-up was 7.3 years in the CCH group and 7.4 years in the surgery group. The 2 groups were compared using 2 methods to control for potential confounding bias: (1) propensity score matching and (2) multivariable analysis accounting for potential confounders.

RESULTS

After propensity score matching, there were 44 patients in each group with similar disease and demographic characteristics. Rates of reintervention and perceived recurrence were significantly higher in the CCH group than the surgery group at a minimum of 5 years following treatment.

CONCLUSIONS

Long-term overall reintervention and perceived recurrence following treatment of Dupuytren contracture affecting a single digit were higher with CCH treatment than surgical fasciectomy when comparing groups with similar baseline characteristics. Our findings may be used to counsel patients on the durability of the outcomes of treatment when considering treatment options for Dupuytren contractures.

Long-term Outcomes of Silastic Arthroplasty of the Thumb Metacarpophalangeal Joint

Background: Silastic metacarpophalangeal arthroplasty (SMPA) has proven to be a durable option for end-stage arthritis in the non-thumb digits, while fusion has been the mainstay procedure for the thumb metacarpophalangeal joint (MP). Few studies exist to comment on the viability of thumb MP arthroplasty. This study reports both survival and objective outcomes following SMPA of the thumb. Methods: In an institutional review board-approved retrospective study, we identified 18 patients who underwent thumb SMPA at a tertiary academic center by 3 board-certified hand surgeons. Primary outcome measures were implant survival and post-operative complications. Secondary outcomes measures were quick Disabilities of the Arm, Shoulder, and Hand (quickDASH) scores, brief Michigan Hand Questionnaire (bMHQ), and postoperative pain as rated by the numerical rating scale. Results: Mean quickDASH and bMHQ scores at final follow-up were 35.6 and 70.6, respectively. The most common short-term complication was clinical deformity, followed by instability. The sole long-term complication was an implant dislocation in a previously asymptomatic patient. All patients reported reduction in pain. Three patients were indicated for revision surgery, 2 for persistent instability, and 1 for implant dislocation. Primary survivorship was 83% at mean follow-up of 5.8 years. Conclusions: Thumb SMPA is a viable option for end-stage arthritis. Pain relief in our series was unanimous. Among those that reported persistent symptoms or required revision, a majority had one or more key preoperative risk factors for failure as currently reported in literature. Larger, prospective series are needed to prove superior longevity and functional outcomes of thumb SMPA versus fusion.

Factors Associated With Poor Outcomes in Acute Forearm Compartment Syndrome

Background: There is limited literature on risk stratification of patients with acute forearm compartment syndrome. The primary objective of this study was to identify factors associated with poor outcomes in patients with acute forearm compartment syndrome. Methods: We retrospectively identified 130 patients with acute compartment syndrome of 130 forearms treated with fasciotomies from January 2000 to June 2015 at 2 Level 1 trauma centers. Poor outcome was defined as a composite variable, including: (1) death; (2) limb amputation; (3) persistent neurological deficit; and (4) contracture. Patient- and treatment-related variables were collected. Bivariate analyses were used to screen for variables associated with poor outcome, and explanatory variables with a value of P < .05 were included in our multivariable logistic regression analyses. Results: Of the 130 patients, 43 (33%) with acute forearm compartment syndrome had poor outcomes, including 5 deaths, 5 limb amputations, 21 persistent neurological deficits, and 31 contractures. Multivariable logistic regression analyses showed that elevated serum creatine kinase at presentation (P < .05) was associated with poor outcomes in patients with acute forearm compartment syndrome. Receiver operating characteristic curve analysis showed that a serum creatine kinase cutoff of 300 U/L yields 92% sensitivity and a serum creatine kinase cutoff of 10 000 U/L yields 95% specificity for poor outcomes in acute forearm compartment syndrome. Conclusions: Elevated creatine kinase levels above 300 U/L are a useful screening test for the highest risk patients with acute forearm compartment syndrome. Levels above 10 000 U/L may play a role in informed consent and counseling regarding expectations.

Acute Radial Head Resection for Fracture: are We Likely to Miss an Essex-Lopresti Injury?

BACKGROUND

Given the current available evidence, surgical treatment of radial head fracture with acute resection is controversial. The aim of this study was to determine whether acute resection of the radial head for a radial head fracture leads to longitudinal forearm instability due to a missed Essex-Lopresti injury.

MATERIAL AND METHODS

A retrospective review was conducted of radial head resections performed for acute radial head fractures at two Level I trauma centers from 2000 to 2018. A total of 11 patients met inclusion criteria. Our primary outcome was a missed Essex-Lopresti injury at time of final clinical follow-up. Long-term telephone follow-up was attempted for QuickDASH, pain scores, and satisfaction scores.

RESULTS

Of the 11 radial head fractures in this study, intraoperative radial pull tests were performed and normal in 6 patients. No patient was found to have a missed Essex-Lopresti injury at a mean of 36.2 months' clinical follow-up after radial head resection. At a mean telephone follow-up of 12.6 years in available patients, mean QuickDASH was 3.4, mean satisfaction was 9.75 out of 10, and no further complication or reoperation was reported.

CONCLUSION

Our findings challenge the dogma that the radial head cannot be safely excised in the setting of acute fracture, even with elbow instability and/or wrist pain, particularly when intraoperative longitudinal stability is assessed by a stress maneuver.

Patient Perception and Preferences for Virtual Telemedicine Visits for Hand and Upper Extremity Surgery

Background: Telemedicine in upper extremity surgery is an evolving modality that provides a viable alternative to the traditional in-person visit for achieving convenient, safe, and cost-effective health care. Our study aimed to identify patient preferences for virtual visits for hand and upper extremity surgery. Methods: An institutional review board approved survey was prospectively administered to all patients >18 years of age, presenting for any complaint to an orthopedic hand and upper extremity clinic at a Level I academic trauma center from September to December 2019. This survey included questions about access and literacy of technology as well as patient preferences regarding virtual visits. The medical record was reviewed to collect demographics, insurance type, and reasons for their visit. Bivariate and multivariate analyses were performed according to survey responses. Results: Two hundred consecutive patients (n) completed surveys. Surveys revealed that >88% of patients own a computer or smartphone, have WiFi access at home, and own a device capable of video chat. In total, 75% of patients reported that they would be moderately or highly comfortable in their ability to use a device for a virtual visit. In bivariate and multivariate analyses, technological literacy and access to a private space to conduct a visit were associated with high interest in virtual visits. Discussion: Telemedicine is a viable alternative to in-person patient visits. Our study demonstrates that most patients are willing and able to participate in a virtual visit for a hand or upper extremity issue.

Clavicle Fractures With Associated Acute Neurovascular Injury

Descriptions of acute neurovascular injury after clavicle fracture are limited to case reports. The objectives of this study were to assess both the prevalence of acute neurovascular injury after midshaft clavicle fracture and the outcomes of early fracture stabilization. A retrospective chart review was conducted of all adult patients with midshaft clavicle fracture who were treated surgically at 2 tertiary care referral centers from January 2010 to March 2019. The records of patients who were identified as having clinical or radiographic evidence of neurovascular compromise were reviewed to assess for deficits on physical examination on presentation, relevant radiographic and electro-diagnostic findings, timing and type of fixation, and time until resolution of symptoms and radiographic union postoperatively. Of the 443 adult patients undergoing surgical treatment for displaced midshaft clavicle fracture, 3 (1%) experienced acute neurovascular compromise and underwent early fixation. In all cases, fracture displacement caused compression of adjacent neurovascular structures in the costoclavicular space. No lacerations of underlying neurovascular structures were encountered intraoperatively, suggesting a pattern of nerve contusion or vascular compression from the initial injury and fracture displacement. Postoperatively, 2 patients had full recovery of preoperative neurologic deficits and 1 patient experienced partial recovery of motor deficits with persistent neuropathic pain. There were no instances of symptomatic vascular insufficiency at final follow-up. Acute neurovascular injury as a result of compression of underlying structures in the costoclavicular space is a rare complication of displaced midshaft clavicle fracture. Early surgical decompression of compressed neurovascular structures and rigid clavicle osteosynthesis can lead to significant postoperative functional improvement.
