Abstract
BACKGROUND The objective of this study was to investigate the outcomes of COVID-19-positive patients undergoing orthopaedic fracture surgery using data from a national database of U.S. adults with a COVID-19 test for SARS-CoV-2. METHODS This is a retrospective cohort study using data from a national database to compare orthopaedic fracture surgery outcomes between COVID-19-positive and COVID-19-negative patients in the United States. Participants aged 18-99 with orthopaedic fracture surgery between March and December 2020 were included. The main exposure was COVID-19 status. Outcomes included perioperative complications, 30-day all-cause mortality, and overall all-cause mortality. Multivariable adjusted models were fitted to determine the association of COVID-positivity with all-cause mortality. RESULTS The total population of 6.5 million patient records was queried, identifying 76,697 participants with a fracture. There were 7,628 participants in the National COVID Cohort who had a fracture and operative management. The Charlson Comorbidity Index was higher in the COVID-19-positive group (n = 476, 6.2 %) than the COVID-19-negative group (n = 7,152, 93.8 %) (2.2 vs 1.4, p<0.001). The COVID-19-positive group had higher mortality (13.2 % vs 5.2 %, p<0.001) than the COVID-19-negative group with higher odds of death in the fully adjusted model (Odds Ratio=1.59; 95 % Confidence Interval: 1.16-2.18). CONCLUSION COVID-19-positive participants with a fracture requiring surgery had higher mortality and perioperative complications than COVID-19-negative patients in this national cohort of U.S. adults tested for COVID-19. The risks associated with COVID-19 can guide potential treatment options and counseling of patients and their families. Future studies can be conducted as data accumulates. LEVEL OF EVIDENCE Level III.

Abstract
STUDY DESIGN Systematic Review and Meta-analysis. OBJECTIVE Postoperative urinary retention (POUR) is a common complication following lumbar spine surgery (LSS) and timely recognition is imperative to avoid long-term consequences. The aim of the current meta-analysis was to systematically review the literature in order to identify risk factors associated with POUR after LSS. METHODS In accordance with PRISMA guidelines, a systematic review of the literature was performed using Pubmed, EMBASE, and MEDLINE database for articles on POUR following LSS. A meta-analysis was performed comparing patients with and without POUR; and the factors associated with this adverse event were analyzed. The pooled data were reported as mean differences with 95% confidence intervals (CI; P < .05). Heterogeneity among the studies was evaluated using the I2 statistic. RESULTS The meta-analysis included 10 studies compromised of 30,300 patients. Based on our analysis, patients who were male, were older in age, underwent instrumented fusion, had diabetes mellitus, coronary artery disease, or benign prostatic hypertrophy had significantly higher risk of developing POUR. Additionally, patients in who developed POUR had significantly longer surgical times and higher volumes of intra-operative fluid administration, as compared with non-POUR patients. The POUR patients also had a significantly higher association with urinary tract infection. Prior surgery, BMI, length of stay, and smoking status did not reveal any statistical association with POUR. CONCLUSIONS Risk factors associated with POUR following LSS include male gender, older age, longer surgical times, fusion procedures, larger volumes of intraoperative infusions, and associated comorbidities like DM, CAD, and BPH.

Abstract
Background: The National COVID Cohort Collaborative (N3C) is an innovative approach to integrate real-world clinical observations into a harmonized database during the time of the COVID-19 pandemic when clinical research on ankle fracture surgery is otherwise mostly limited to expert opinion and research letters. The purpose of this manuscript is to introduce the largest cohort of US ankle fracture surgery patients to date with a comparison between lab-confirmed COVID-19–positive and COVID-19–negative. Methods: A retrospective cohort of adults with ankle fracture surgery using data from the N3C database with patients undergoing surgery between March 2020 and June 2021. The database is an NIH-funded platform through which the harmonized clinical data from 46 sites is stored. Patient characteristics included body mass index, Charlson Comorbidity Index, and smoking status. Outcomes included 30-day mortality, overall mortality, surgical site infection (SSI), deep SSI, acute kidney injury, pulmonary embolism, deep vein thrombosis, sepsis, time to surgery, and length of stay. COVID-19–positive patients were compared to COVID-19–negative controls to investigate perioperative outcomes during the pandemic. Results: A total population of 8.4 million patient records was queried, identifying 4735 adults with ankle fracture surgery. The COVID-19–positive group (n=158, 3.3%) had significantly longer times to surgery (6.5 ± 6.6 vs 5.1 ± 5.5 days, P = .001) and longer lengths of stay (8.3 ± 23.5 vs 4.3 ± 7.4 days, P < .001), compared to the COVID-19–negative group. The COVID-19–positive group also had a higher rate of 30-day mortality. Conclusion: Patients with ankle fracture surgery had longer time to surgery and prolonged hospitalizations in COVID-19–positive patients compared to those who tested negative (average delay was about 1 day and increased length of hospitalization was about 4 days). Few perioperative events were observed in either group. Overall, the risks associated with COVID-19 were measurable but not substantial. Level of Evidence: Level III, retrospective cohort study.

Abstract
OBJECTIVE The purpose of this study is to characterize illegal questions as defined by federal law and to assess their impact on applicants' rank lists across four surgical specialties. DESIGN A survey was developed and sent to surgical specialty residency applicants. The survey asked demographics, the frequency of questions about age, gender, religion, sexual orientation, family status and impact on final rank list. Applicants were asked to respond anonymously based on their experience at all institutions at which they interviewed during the interview cycle. Results were compared by applicant specialty and gender. SETTING A large university-affiliated academic medical center PARTICIPANTS: Survey was administered to 3854 applicants (comprising between 28.9% and 41.2% of applicants nationwide) to general surgery, orthopaedic surgery, urology, and otolaryngology residency programs at a single institution during the 2018 and 2019 cycles. A total of 1066 applicants completed the survey. RESULTS A total of 789 (74.0%) of applicants reported being asked at least one illegal question during the interview process at any institution. Applicants to orthopaedic surgery programs were most likely to be asked illegal question (n = 315, 81.6%), and general surgery applicants were least likely to be asked illegal questions (n = 324, 66.8%, p < 0.001). Females were more likely than males to be asked about gender (n = 99, 26.3% vs. n = 18, 2.6%, p < 0.001) and plans for pregnancy (n = 78, 20.8% vs. n = 78, 11.4%, p < 0.001). 152 (19.4%). Applicants reported that being asked an illegal question lowered a program on their rank list. Female applicants were more likely to lower a program on their rank list as a result of an illegal question (n = 102, 35.4% vs. n = 50, 10.1%, p < 0.001). CONCLUSIONS Illegal questions in surgical specialty residency interviews are common, vary by specialty and applicant gender, and lower programs on applicants' rank lists. This data should serve to inform larger and more inclusive studies in the future. Programs should focus on educating interviewers on illegal topics in an effort to minimize illegal topics that may alienate applicants and contribute to workplace discrimination.

Abstract
OBJECTIVES Check-in kiosks are increasingly used in health care. This project aims to assess the effects of kiosk use upon check-in duration, point of service (POS) financial returns, and patient satisfaction. METHODS Six kiosks were implemented in a large academic orthopedic clinic, and check-in duration for 8.5 months following implementation and POS returns for 10.5 months before and after implementation were analyzed. Consumer Assessment of Healthcare Providers and Systems Clinician and Group survey and self-devised surveys recorded patient satisfaction. RESULTS Cumulatively, 28,636 kiosk-based patient encounters were analyzed. Compared with historical norms, check-in duration decreased 2 minutes, 47 seconds (P < 0.001). Daily gross and individual POS returns increased $532.13 and $1.89, respectively (P < 0.001). Satisfaction surveys were completed by 719 of 1376 consecutive patients (52% response rate), revealing 12% improvement (P < 0.001), but Consumer Assessment of Healthcare Providers and Systems Clinician and Group survey responses demonstrated no change (P = 0.146, 0.928, and 0.336). CONCLUSIONS Kiosks offer to reduce check-in duration and increase POS revenue without negatively affecting patient satisfaction.

Abstract
PURPOSE This retrospective study aimed to assess the feasibility of continuing clopidogrel therapy during the perioperative period in elective cervical and thoracolumbar surgery. METHODS After IRB approval, medical records of patients requiring one or two-level surgery over a two-year period (2015-2017) while receiving clopidogrel were reviewed for relevant outcomes. Over the same period, a control group of patients not receiving clopidogrel perioperatively was formed. RESULT In total, 136 patients were included: 37 clopidogrel and 99 control, with a mean age of 64.8 years. Between clopidogrel and control respectively, operative time was 86.7 min and 86.7 min (p = 0.620); blood loss was 127.0 cc and 117.5 cc (p = 0.480); drain output was 171.2 cc and 190.7 cc (p = 0.354); length of stay was 1.8 days and 1.5 days (p = 0.103). Two clopidogrel patients and 1 control patient had complications. Two clopidogrel patients and 1 control patient were readmitted within 30 days. CONCLUSIONS Remaining on clopidogrel therapy during elective spine surgery results in no difference in operative time, blood loss, drain output, length of stay, or readmission. Precaution should be taken in cervical procedures as the drain output in clopidogrel patients was increased and complications in this region can be severe.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVES To evaluate the rate of nonoperative treatment failure for cervical facet fractures while secondarily validating computed tomography-based criteria proposed by Spector et al for identifying risk of failure of nonoperative management. METHODS Single-level or multilevel unilateral cervical facet fractures from 2007 to 2014 were included. Exclusion criteria included spondylolisthesis, dislocated or perched facets, bilateral facet fractures at the same level, floating lateral mass, thoracic or lumbar spine injuries, or spinal cord injury. Patients were placed into 3 groups for evaluation: immediate operative management, successful nonoperative management, and failed nonoperative treatment requiring surgical intervention. RESULTS Eighty-eight patients (106 facets) were included. Twenty-one patients underwent operative treatment with anterior cervical discectomy and fusion or posterior spinal instrumentation and fusion without any failures. Sixty-seven of these patients were treated nonoperatively with either a hard collar (n = 62) or halo vest (n = 5). Eleven patients failed nonoperative treatment (16.4%), all with an absolute fracture height of at least 1 cm and 40% involvement of the absolute height of the lateral mass. Of the 56 patients successfully treated through nonoperative measures, 8 (14.3%) had fracture measurements exceeding both operative parameters. CONCLUSION We conclude that it is safe and appropriate for patients with unilateral cervical facet fractures to receive a trial period of nonoperative management. However, patients who weigh over 100 kg, have comminuted fractures, or have radiographic measurements outside of the proposed computed tomography criteria for nonoperative treatment should be educated on the risks of treatment failure.

Abstract
Objective: The objective of this study is to evaluate the the reliability of magnetic resonance imaging (MRI) in diagnosing alar ligament disruption in patients with potential atlanto-occipital dissociation (AOD). Materials and Methods: Three-blinded readers performed retrospective review on 6 patients with intra-operative confirmed atlanto-occipital dissocation in addition to a comparison cohort of patients with other cervical injuries that did not involve the atlanto-occipital articulation. Ligament integrity was graded from 1 to 3 as described by Krakenes et al. The right and left ligaments were assessed separately. Inter-observer agreement by patient, by group (AOD vs. non-AOD), and intra-observer agreement was calculated using weighted Cohen's kappa. Results: Interobserver agreement of alar ligament grade for individual patients ranged from slight to fair (κ = 0.05–0.30). Interobserver agreement of alar ligament grade for each group (AOD vs. non-AOD) ranged from fair to substantial (κ = 0.37–0.66). No statistically significant difference in categorical analysis of groups (AOD vs. non-AOD) and grade (0–1 vs. 2–3) was observed. Intraobserver agreement of individual patient's alar ligament grade ranged from moderate to substantial (κ = 0.50–0.62). Conclusion: The use of MRI to detect upper cervical ligament injuries in AOD is imperfect. Our results show inconsistent and unsatisfactory interobserver and intraobserver reliability in evaluation of alar ligament injuries. While MRI has immense potential for detection of ligamentous injury at the craniovertebral junction, standardized algorithms for its use and interpretation need to be developed.

Abstract
BACKGROUND CONTEXT Patient satisfaction is and will continue to become an important metric in the American health care system. To our knowledge, there is no current literature exploring the factors that impact patient satisfaction in outpatient orthopedic spine surgery clinic. PURPOSE The purpose of this study was to determine which factors impact patient satisfaction in an outpatient orthopedic spine clinic. STUDY DESIGN This is a case series, level of evidence IV. PATIENT SAMPLE We reviewed the Press Ganey Associates database to identify patients seen in an orthopedic spine surgery clinic from 2013 to 2015. OUTCOME MEASURES Outcome measures were self-reported, which included visual analog pain scores and Press Ganey satisfaction scores. METHODS Retrospective computerized Press Ganey survey review was performed to identify patient demographics and patient visit characteristics. Bivariate analysis was used by splitting the patient response into the following: 0-3 (not satisfied), 4-7 (somewhat satisfied), and 8-11 (satisfied). Kruskal-Wallis test and Fisher exact test were used to evaluate the significance of patient and visit characteristics. Any variable that had a p-value less than .20 was subjected to the Poisson regression model. RESULTS Overall, 353 patients were seen in an orthopedic spine surgery clinic and completed the Press Ganey survey. Three hundred and thirty-two patients were satisfied with their visit. Patients who were satisfied had a mean pain score of 4.02; patients who were somewhat satisfied or not satisfied had a pain score of 7 and 6, respectively (p=.009). Of 21 patients who felt the provider did not spend enough time with him or her, five (24%) patients were not satisfied with their visit. Poisson regression model confirmed significance of pain score and "provider time spent with you." Most impactful was "provider spent enough time with you" where a "yes, definitely" answer predicted a nearly 60% increase in Press Ganey overall satisfaction score. CONCLUSIONS Two patient variables that have a statistical significance on Press Ganey patient satisfaction scores were pain score and "provider spent enough time with you."

Abstract
BACKGROUND Adult spine deformity surgery (ASDS) is a significantly invasive procedure with a relatively high complication rate. The thirty-day hospital readmission rate following surgery is an important quality measure monitored by multiple quality reporting agencies. PURPOSE This study seeks to determine the risk factors for 30- day readmission rate in patients undergoing ASDS and identify the risk factors associated with readmission. STUDY DESIGN This is a retrospective multicenter study. METHODS The National Surgical Quality Improvement Program database, which is a large multi-institutional database, was searched for patients that underwent ASDS from 2011 to 2013. The patients were identified by searching seven Current Procedural Terminology codes most commonly used for spinal deformity surgery. Twenty-seven preoperative variables, including patient demographics and comorbidities, intraoperative parameters, and postoperative complications were analyzed to identify risk factors for readmission. RESULTS A total of 747 adult patients who underwent ASDS were identified. Of the 747 patients, 7.5% (56/747) were readmitted within 30 days. The most common causes of readmission were infection (n=11), hematoma or seroma formation (n=5), and postoperative pain (n=3). Univariate analysis revealed male gender (p=.038, odds ratio [OR]=1.83) and pulmonary embolism before discharge (p=.048, OR=8.44) to be associated with readmission. In multivariate analysis, obesity (p=.047, OR=1.80), peripheral vascular disease (p=.045, OR=17.52), pulmonary embolism before discharge (p=.012, OR=10.35), and total or partial dependent preoperative functional health status (p=.041, OR=2.45), were found to be independent risk factors for readmission. Age, smoking, and resident involvement during surgical procedure were among the many factors not associated with increased risk of readmission. CONCLUSIONS The 30-day readmission rate for ASDS is increasingly becoming a significant health-care quality indicator. Patients with the aforementioned significant risk factors should be closely followed up, which can potentially avoid subsequent readmission.

Abstract
Study Design The study is a case report. Objective The authors aim to report an unusual injury pattern in a patient previously treated for thoracic kyphoscoliosis. Methods A postoperative (computed tomography) CT of a healthy 24-year-old man who underwent posterior instrumentation and fusion for a kyphoscoliosis deformity was compared with a CT performed after a motor vehicle accident (MVA) 1 year later, which resulted in an extension-distraction injury of T8 with no neurologic deficit. Cobb angles of the thoracic sagittal images of both CTs were measured using a digital measuring device and the values were recorded. Results Initial postoperative sagittal CT images demonstrate a 67-degree residual thoracic kyphosis compared with the post-MVA sagittal CT images, which reveal a 54-degree thoracic kyphosis, a 13-degree improvement in sagittal alignment. Conclusion It is unusual for a patient with long posterior instrumentation of the spine to sustain a spinal fracture without breakage of the rods, which were 6-mm nickel-titanium alloy with two crosslinks. Although sustaining plastic deformation, the rods maintained their integrity to the degree that the patient required no subsequent treatment to his spine at 12 months follow-up. It is rare to sustain a vertebral fracture without implant failure, which occurred in this case.

Abstract
This review identifies a number of exciting new developments in the understanding of vision in cartilaginous fishes that have been made since the turn of the century. These include the results of studies on various aspects of the visual system including eye size, visual fields, eye design and the optical system, retinal topography and spatial resolving power, visual pigments, spectral sensitivity and the potential for colour vision. A number of these studies have covered a broad range of species, thereby providing valuable information on how the visual systems of these fishes are adapted to different environmental conditions. For example, oceanic and deep-sea sharks have the largest eyes amongst elasmobranchs and presumably rely more heavily on vision than coastal and benthic species, while interspecific variation in the ratio of rod and cone photoreceptors, the topographic distribution of the photoreceptors and retinal ganglion cells in the retina and the spatial resolving power of the eye all appear to be closely related to differences in habitat and lifestyle. Multiple, spectrally distinct cone photoreceptor visual pigments have been found in some batoid species, raising the possibility that at least some elasmobranchs are capable of seeing colour, and there is some evidence that multiple cone visual pigments may also be present in holocephalans. In contrast, sharks appear to have only one cone visual pigment. There is evidence that ontogenetic changes in the visual system, such as changes in the spectral transmission properties of the lens, lens shape, focal ratio, visual pigments and spatial resolving power, allow elasmobranchs to adapt to environmental changes imposed by habitat shifts and niche expansion. There are, however, many aspects of vision in these fishes that are not well understood, particularly in the holocephalans. Therefore, this review also serves to highlight and stimulate new research in areas that still require significant attention.

Abstract
Pyogenic vertebral osteomyelitis (PVO) can be treated most often by medical management. For those failing with medical management, surgical delay can result in increased morbidity. Therefore, the ability to predict failure of medical management on presentation would greatly improve the outcome. This study determines the ability of the presenting magnetic resonance imaging scan to predict failure of nonoperative management at the onset of treatment. A cohort of patients with PVO, initially treated medically, was reviewed. Imaging, demographics, and clinical data of patients successfully treated medically were compared with those ultimately requiring surgical treatment. The extent of signal change on the T1-weighted sagittal images of the affected motion segment was determined for each group. Twenty-two patients were included in the study. Patients successfully treated medically averaged 57%+/-19% of motion segment involvement, whereas those failing conservative treatment averaged 89%+/-18%. Using 90% involvement as an indication for initial surgery would have a sensitivity of 78% and specificity of 93%. Patients with thoracolumbar PVO who have 90% or higher involvement of an affected motion segment should be considered for early operative management.

Abstract
Short segment instrumentation for thoracolumbar fractures or fracture dislocations continues to be controversial. Recently, a load-sharing classification score was developed to help predict failure of posterior instrumented fusion alone used for highly comminuted and kyphotic fractures. Twenty-two patients treated with short-segment posterior instrumentation for thoracolumbar fractures were retrospectively reviewed. Although posterior instrumented fusion was used for fractures with a relatively high load sharing classification score, the load-sharing classification score was not predictive of posterior instrumentation failure. Single-level cephalad instrumentation failed at a higher rate than two-level cephalad instrumentation.

Abstract
STUDY DESIGN A case of a patient in whom vertebral osteonecrosis developed after intradiscal electrothermal therapy is reported. OBJECTIVE To illustrate a potential complication of intradiscal electrothermal therapy and potential strategies to avoid it. SUMMARY OF BACKGROUND DATA Thermal energy delivered in a controlled fashion directly to the annular wall and disc nucleus has been developed as an alternative to surgical methods for treating internal disc disruption. Although 2-year follow-up data are available, few complications and no vertebral body injury have been reported. METHODS After intradiscal electrothermal therapy, a patient exhibited MRI changes consistent with osteonecrosis in the adjacent vertebral body. The clinical and radiologic findings are presented, along with a review of the pertinent literature. RESULTS The magnetic resonance images, the temporal relation of intradiscal therapy, and the patient's clinical symptoms are consistent with focal osteonecrosis of the vertebral body. CONCLUSIONS This case study highlights a potential complication of intradiscal electrothermal therapy. Catheter placement may expose cortical and cancellous bone to temperatures well within the range reported to induce necrosis. In addition, focal disruption of the endplate may prove to be a relative contraindication for intradiscal electrothermal therapy.

Abstract
Isthmic spondylolisthesis, or spondylolisthesis due to a lesion of the pars interarticularis, is a common source of pain and disability in both the pediatric and adult population. This review examines the current diagnostic and treatment options for patients with this condition. It also reviews the results of the various interventions to facilitate the surgeon in choosing the appropriate treatment option for any given patient.

Abstract
STUDY DESIGN A rabbit model of posterolateral spine fusion was used to investigate the effect of nicotine on cytokine expression during spine fusion. OBJECTIVES To determine the effects of nicotine on the known gene expression pattern of bone morphogens and related proteins expressed during spine fusion. SUMMARY OF BACKGROUND DATA The mechanism by which nicotine increases the pseudarthrosis rate of spine fusion is unknown. Recently, a distinct temporal and spatial pattern of cytokine expression during bone formation has been described. The authors hypothesized that nicotine would alter this known pattern, thereby revealing the mechanism by which nicotine exerts its effect. METHODS Twenty-eight New Zealand White rabbits underwent posterolateral spine fusion with autogenous bone graft. Fourteen rabbits received systemic nicotine by a miniosmotic pump. Fusions were harvested at 0, 2, 5, and 7 days and 2, 3, and 4 weeks after arthrodesis. Specimens were divided into the outer zones adjacent to the transverse processes and the central zones between the transverse processes. Gene expression of type I and II collagen, bone morphogenic protein-2, -4, and -6 and basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) was then measured at each time point in each of the two zones. RESULTS Nicotine inhibited expression of all cytokines measured, mainly in the central zone. However, the previously described temporal and spatial patterns of expression were preserved. CONCLUSIONS Nicotine inhibits expression of a wide range of cytokines, including those associated with neovascularization and osteoblast differentiation. Therefore, the effects of nicotine appear to involve more than just local vasoconstriction.

Abstract
STUDY DESIGN This study evaluated the long-term results of Klippel-Feil syndrome in patients with congenital scoliosis. OBJECTIVES To determine the incidence of cervical and cervical-related symptoms of patients who have Klippel-Feil syndrome associated with congenital scoliosis. SUMMARY OF BACKGROUND DATA Many authors have described the association of Klippel-Feil syndrome and congenital scoliosis. In this population of patients, cervical lesions often are discovered incidentally. The significance of these lesions is unknown. METHODS Thirty-two patients with congenital scoliosis and Klippel-Feil syndrome were observed for more than 10 years. They were questioned specifically about cervical and cervical-related symptoms. All patients had sequential cervical radiographs and physical examinations. RESULTS Despite rather dramatic radiographic appearances, only seven (22%) of the 32 patients had cervical or cervical-related symptoms, with two patients requiring surgery for their cervical lesions. The extent of the deformities and the average number of cervical vertebrae fused and cervical fusion-patterns were statistically similar between the symptomatic and asymptomatic groups. Patients fused to the cervicothoracic junction for management of their deformities had a significantly increased incidence of cervical symptoms. Also, patients with congenital stenosis had a significantly greater incidence of upper extremity pain. CONCLUSIONS Only a small number of patients with Klippel-Feil syndrome and congenital scoliosis developed cervical symptoms. No fusion pattern that placed the patient at greater risk for developing symptoms could be identified. Factors that did lead to a greater incidence of cervical symptoms were fusion to the cervicothoracic junction and congenital cervical stenosis.

Abstract
Three hundred one primary cemented total knee arthroplasties were performed in 289 patients. Two different prostheses were used; 148 knees received the Miller-Galante I prosthesis and 153 knees received the Press Fit Condylar prosthesis. Minimum followup was 2 years. The groups were similar in all parameters both preoperatively and postoperatively, with the exception of the patellofemoral complication rate. Knees that were implanted with the Miller-Galante I prosthesis experienced a complication rate of 10.1%, while those with the Press Fit Condylar prosthesis experienced a complication rate of 0.7%. The distinct difference in the patellofemoral complication rate may be due to the differences in design of the femoral component. Features that may have contributed to increased patellofemoral morbidity included a short, narrow anterior flange; a shallow patellar groove; and an abrupt anterior to distal transition with a smaller radius of curvature. Because subtle design difference can have a profound effect on clinical outcome, long term evaluation of new designs should be completed before widespread use. The clinician also should be aware of the desirable design features when choosing a component.
