Distal radius fractures in older patients: is anatomic reduction necessary?

Dynamic hand and finger load distribution patterns in the first year following surgically treated distal radius fracture

BACKGROUND

Manugraphy is a relatively young technique for assessing dynamic load distribution when gripping a cylinder. Thereby, dynamic hand grip function is objectivated, providing a more detailed insight than with other clinical assessment tools. Analysis of changes in grip patterns following a distal radius fracture provides a new perspective on documenting the recovery process of this common injury. Our aim was also to investigate the relationships between load distribution during a maximum force grip and other hand function parameters to better understand the implications for follow-up and rehabilitation.

METHODS

Assessment of the QuickDASH score, finger and wrist range of motion, grip strength as well as grip load distribution using manugraphy was performed 3, 6 and 12 months following isolated surgically treated distal radius fractures. Using special software, each finger ray as well as the thenar and hypothenar were defined on the digital pressure map and the contribution to the total force was calculated for each region.

RESULTS

After 3 months, 49 patients participated in the follow-up examinations, after 6 months 38 patients and after 12 months 35 patients. When the QuickDASH score decreased significantly, the wrist range of motion and grip strength recovered to more than 90% of the values of the uninjured side within the first year after fracture treatment. The cumulative analysis of the load distribution showed that after 3 months, the thumb and index finger exerted a greater proportion of the total grip strength than did the uninjured hand, whereas the contributions of the thenar and hypothenar were smaller. These changes diminished at 6 and 12 months, respectively. The changes in grip pattern showed significant correlations with grip strength and partly with range of motion of finger and wrist as well as the QuickDASH score.

CONCLUSIONS

The dependence between changes in load distribution and different hand function parameters implies the particular additional value and validity of this helpful technique for individual assessment and rehabilitation of hand function. Early detection of persisting imbalances of dynamic load distribution might support clinical decision-making in the postoperative course during rehabilitation.

Association between distal radius fracture malunion and patient-reported disability: a systematic review and meta-analysis

Purpose

To assess whether distal radius fracture (DRF) malunion is associated with greater patient-reported disability.

Methods

We searched PubMed, EMBASE, and Cochrane databases up to 21 May 2023. Two reviewers independently screened retrieved titles/abstracts and assessed the full text of potentially eligible articles to identify cohort studies and randomized controlled trials reporting outcomes of DRF in adults at least 12 months after fracture, confirmed radiologically 3 months or longer after fracture. We excluded studies not reporting patient-reported outcomes according to malunion and studies judged to have a high risk of bias, as assessed independently by two reviewers using the Quality In Prognosis Studies tool. To express the overall effect of malunion on patient-reported disability, we calculated the standardized mean difference (SMD) with a 95% CI.

Results

Six studies with 898 patients (77% women) were included; five involved adults of all ages, and one restricted to patients aged 65 years and older. In the meta-analysis including the five studies with adults of all ages (1047 observations), the SMD was 0.58 (95% CI: 0.42-0.74; P < 0.001), favoring no malunion, with no statistically significant heterogeneity or publication bias. In the meta-analysis including all six studies (1193 observations), the SMD was 0.51 (95% CI: 0.35-0.67; P < 0.001), favoring no malunion, with moderate but significant heterogeneity.

Conclusion

Malunion of distal radius fracture is associated with significantly greater patient-reported disability with a moderate magnitude in terms of clinical importance. The study does not address the possible influence of age or treatment methods.

How Preoperative Closed Reduction and Time to Surgery Impact Postoperative Palmar Inclination in Distal Radius Fractures

Background: The anatomical reconstruction of the wrist is the aim when treating distal radius fractures. Current literature on the importance of preoperative reduction in fractures that are treated operatively is limited. Methods: This study investigated the effect of the preoperative closed reduction of distal radius fractures on the day of trauma and the time to surgery on postoperative palmar inclination. A total of eighty patients (48 females and 32 males, mean age 55.6 years) were studied retrospectively. All patients were treated with an open reduction and internal fixation. The palmar inclination angle was measured using X-rays by two investigators, and the interobservers and pre- and post-reduction parameters were compared. Results: When the surgical management of closed distal radius fractures is required, neither initial repositioning nor a delay of up to 14 days to the surgical treatment influences postoperative palmar inclination. Conclusions: The significance of preoperative reduction of distal radius fractures without neurovascular or extensive soft tissue damage is limited and is not leading to improved outcomes. When surgery is about to be performed, surgeons should carefully consider if reduction is really vital preoperatively. Level of evidence: III.

Radiological outcomes following surgical fixation with wires versus moulded cast for patients with a dorsally displaced fracture of the distal radius: a radiographic analysis from the DRAFFT2 trial

Aims

The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury.

Methods

Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient's initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed.

Results

Patients treated with surgical fixation with wires had less dorsal angulation of the radius versus those treated in a moulded cast at six weeks after manipulation of the fracture; the mean difference of -4.13° was statistically significant (95% confidence interval 5.82 to -2.45). There was no evidence of a difference in radial shortening. However, there was no correlation between these radiological measurements and PROMs at any timepoint in the 12 months post-injury.

Conclusion

For patients with a dorsally displaced distal radius fracture treated with a closed manipulation, surgical fixation with wires leads to less dorsal angulation on radiographs at six weeks compared with patients treated in a moulded plaster cast alone. However, the difference in dorsal angulation was small and did not correlate with patient-reported pain and function.

Baseline predictors related to functional outcomes in patients older than sixty years with complex regional pain syndrome type 1 after distal radius fracture treated conservatively: a prospective observational study

PURPOSE

This study aimed to analyze baseline predictors of functional outcomes six weeks and at one year follow-up in patients older than 60 years with complex regional pain syndrome type 1 (CRPS I) after distal radius fracture (DRF).

METHODS

A total of 120 patients with CRPS I after DRF were prospectively recruited. Presumptive relevant factors were collected and analyzed as potential baseline predictors. Additionally, functional outcomes were assessed at the beginning of physiotherapy treatment, at six weeks after finishing physiotherapy treatment, and at one year follow-up. Patient-Rated Wrist Evaluation; Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire; Jamar dynamometer; and visual analog scale (VAS) were assessed.

RESULTS

All participants completed the study. At 6 weeks, the main results showed an association of lower values of grip strength with female sex (p = 0.010), intra-articular DRFs (p = 0.030), longer immobilization time (p = 0.040), lower levels of physical activity (p < 0.001), higher levels of kinesiophobia (p = 0.010), and anxiety (p = 0.020). At 1-year follow-up, the results showed an association of lower values of DASH with higher BMI (p < 0.001) and longer immobilization time (p < 0.001); and higher values of VAS showed an association with older age (p = 0.010), higher BMI (p = 0.010), and lower levels of physical activity (p = 0.040).

CONCLUSION

At six weeks, factors such as BMI, immobilization time, physical activity, and kinesiophobia are associated with lower functional outcomes. Additionally, at one year follow-up, BMI, immobilization time, and physical activity continue to be associated with lower functional outcomes in patients with CRPS I after DRF treated conservatively.

Analysis of Postoperative Distal Radius Fracture Outcomes in the Setting of Osteopenia and Osteoporosis for Patients with Comorbid Conditions

Purpose

Distal radius fractures (DRFs) are among the most common orthopedic injuries, especially in the elderly. A wide variety of approaches have been advocated as successful treatment modalities; yet, there remains variability in practice patterns of DRF in patients with osteoporosis and osteopenia. Using large data set analysis, we sought to determine the risk profile of operative fixation of DRF in patients with low bone mineral density.

Methods

A commercially available health care database, PearlDiver, was queried for all patients who underwent open reduction internal fixation of DRFs between 2010 and 2020. The study population was divided into groups based on the presence or absence of osteopenia or osteoporosis and was further classified by patients who were receiving bisphosphonate therapy. Complication rates were calculated, including rates of malunion, surgical site infection, osteomyelitis, hardware failure, and hardware removal. Five-year future fragility fractures were defined in hip, vertebrae, humerus, and wrist fractures. Chi-square analysis and logistic regression were performed to determine an association between these comorbidities and various postoperative complications.

Results

A total of 152,926 patients underwent open reduction internal fixation of a DRF during the study period. Chi-square analysis of major complications at 3 months showed a statistically significant increase in malunion in patients with osteopenia (P = .05) and patients with osteoporosis (P = .05) who underwent open reduction internal fixation. Logistic regression analysis at 12 months after surgery demonstrated that osteopenia was associated with an increased risk of hardware failure (P < .0001), hardware removal (P < .0001), surgical site infection (P < .0001), and malunion (P = .004). Osteoporosis was associated with a significantly increased risk of hardware failure (P = .01), surgical site infection (P < .0001), and malunion (P < .0001).

Conclusions

We demonstrated, using large data set analysis, that DRF patients with osteopenia and osteoporosis are predicted to be at increased risk of multiple postoperative complications, and thus, bone density should be strongly considered in treatment planning for these patients.

Does Radiographic Alignment Correlate With Patient-Reported Functional Outcomes and Posttreatment Complications in Older Patients Treated for Wrist Fractures?

PURPOSE

Surgical treatment of distal radius fractures provides better fracture alignment than closed reduction; however, surgical treatment does not lead to better patient-reported function at 12 months. The aims of this study were to report the radiographic outcomes from the Combined Randomized and Observational Study of Surgery for Fractures In the distal Radius in the Elderly trial, investigate the association between radiographic outcomes and patient-reported function, and explore whether this association was affected by posttreatment complications and direction of malalignment.

METHODS

This study used the outcomes of the Combined Randomized and Observational Study of Surgery for Fractures In the distal Radius in the Elderly trial, which is a combined randomized and observational trial that compared volar-locking plate fixation with closed reduction and cast immobilization, to treat distal radius fractures in patients aged ≥60 years. Four radiographic outcomes (dorsal angulation, radial inclination, ulnar variance, and articular step) were reported at the following three time frames: (1) baseline, (2) after treatment, and (3) ≥6 weeks by treatment group. Secondary analysis was correlation of 12-month patient-reported function scores with 6-week radiographic measures for each of four radiographic parameters, and a subgroup analysis was conducted to investigate if this was affected by posttreatment complications. Tertiary analysis investigated if direction of malalignment affected the secondary analysis.

RESULTS

We recruited 300 participants (166 randomized and 134 observational); 113 had volar-locking plate fixation, and 187 had closed reduction. There were no between-group differences for each of the four pretreatment radiographic parameters, but there were between-treatment group differences for all four radiographic parameters apart from articular step. We found no association between patient-reported function at 12 months and each of the four radiographic parameters at 6 weeks. This lack of association was unaffected by posttreatment complications and the direction of malalignment.

CONCLUSIONS

For patients with wrist fractures aged ≥60 years, final radiographic alignment did not correlate with patient-reported function at 12 months. These findings were not affected by treatment type, and there was no association between radiographic alignment and posttreatment complications.

Does access through the pronator quadratus influence pronation strength in palmar plate fixation of distal radius fractures in elderly patients?

INTRODUCTION

Palmar plate fixation of the distal radius fracture involves dissecting the pronator quadratus (PQ). This is regardless of whether the approach is radial or ulnar to the flexor carpi radialis (FCR) tendon. It is not yet clear whether and to what extent this dissection leads to a functional loss of pronation or pronation strength. The aim of this study was to investigate the functional recovery of pronation and pronation strength after dissection of the PQ without suturing.

MATERIALS AND METHODS

From October 2010 to November 2011, patients aged over 65 with fracture were prospectively enrolled in this study. Fracture stabilisation was performed via the FCR approach without suturing the PQ. Follow-up examinations took place 8 weeks and 12 months postoperatively, and pronation and supination strength were analysed by means of an especially developed measuring device.

RESULTS

212 patients were initially screened and 107 were enrolled. The range of motion compared to the healthy opposite side was Ext/Flex 75/66% 8 weeks postoperatively. Pronation was 97% with a pronation strength of 59%. After 1 year, the scores improved to Ext/Flex 83/80%. Pronation recovered to 99% and pronation strength to 78%.

CONCLUSION

The present study can show a recovery of pronation as well as pronation strength in a large patient population. At the same time, the pronation strength is still significantly lower 1 year after the operation than on the opposing healthy side. As the pronation strength recovers as the grip strength and is at all times on a par with the supination strength, we believe that we can continue to refrain from re-fixating the pronator quadratus.

Changes in the Functional Range of Motion of the Thumb Metacarpophalangeal Joint After Trapeziometacarpal Arthrodesis for Patients With Advanced Trapeziometacarpal Osteoarthritis

PURPOSE

Advanced-stage trapeziometacarpal (TMC) osteoarthritis of the thumb often presents with concomitant hyperextension deformity of the metacarpophalangeal (MCP) joint. Although several studies have reported simultaneous procedures to correct this deformity, the indication for these procedures remains controversial. The purpose of this study was to evaluate changes in the range of motion (ROM) of the thumb MCP joint before and after TMC arthrodesis.

METHODS

We evaluated the functional flexion and extension and functional ROM of the MCP joints during the performance of 10 activities of daily living tasks before and after TMC arthrodesis in 10 thumbs of 9 patients with Eaton stage III TMC osteoarthritis and hyperextension deformity of the MCP joint.

RESULTS

The mean functional flexion of the MCP joint increased from 26° to 38°, and the mean functional extension of the MCP joint decreased from 16° to 5° of hyperextension. There was no change in the mean total arc of functional ROM of the MCP joint.

CONCLUSIONS

The MCP joint motion shifted from extension to flexion after TMC arthrodesis, and the total arc of functional ROM of the MCP joint was similar before and after arthrodesis.

Outcome Metrics in the Treatment of Distal Radius Fractures in Patients Aged Above 50 Years: A Systematic Review

BACKGROUND

The inclusion of patient-reported outcome measures (PROMs) serves to better quantify aspects of patient outcomes missed with objective measures, including radiographic indices and physical examination findings. We hypothesize that PROMs are inconsistently and heterogeneously captured in the treatment of distal radius fractures.

METHODS

We performed a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines of all level I and II randomized controlled trials (RCTs) of distal radius fracture treatment of any modality for those older than 50 years of age from January 2008 to January 2018. A total of 23 studies were included in the final analysis. The metrics used by each study to assess outcomes were collected, compared, and described.

RESULTS

Physical examination findings and radiographic measures were reported in 70% and 74% of studies, respectively. Patient-reported outcomes measures were used to assess outcomes in 74% of studies. Only the Disabilities of the Arm, Shoulder, and Hand was used in greater than half of the studies (57%). Pain scores were assessed in 39% of studies and complications in only 26%.

CONCLUSIONS

There is substantial heterogeneity and lack of standardization in the collection of both objective outcome measures and PROMs in level I and II RCTs for the treatment of distal radius fractures. The ability to compare between studies or aggregate data among studies is therefore limited. Radiographic and physical examination findings remain frequently reported despite known limitations of these metrics. The routine collection of PROMs after the treatment of distal radius fractures can ensure care is directed toward improving what is most important to patients.

Treatment of Distal Radius Fractures with Bridging External Fixator with Optional Percutaneous K-Wires: What Are the Right Indications for Patient Age, Gender, Dominant Limb and Injury Pattern?

The aim of this retrospective study was to evaluate the medium-term clinical and functional outcomes of patients with closed, displaced, and unstable, simple or complex, intra- and extra-articular distal radius fractures (DRFs) treated with a bridging external fixator (BEF) and optional K-wires (KWs). AO classification was used to differentiate the injuries radiographically. Clinical-functional outcomes were evaluated using the Patient-Rated Wrist and Hand Evaluation Score (PRWHE Score) and the Quick Disabilities of the Arm Shoulder and Hand Score (QuickDASH). A total of 269 dorsally displaced fractures of 202 female (75%) and 67 male subjects (25%) were included, with a mean follow-up of 58.0 months. Seventy-five patients (28%) were treated by additional KWs. No differences were found comparing the two groups of patients (BEF vs. BEF + KWs) regarding age, sex, and fracture side (dominant vs. non-dominant). PRWHE and QuickDASH scores were lower in the BEF + KWs group compared to the BEF group (p < 0.0001 and p = 0.0007, respectively). Thus, patients treated with KWs had a better clinical outcome. Beta multivariate regression analysis confirmed that patients of the BEF + KWs group exhibited a better PRWHE score but not a better QuickDASH score. Patients treated by the BEF + KWs with the fracture on the dominant site were characterised by better clinical outcomes. Older patients had a better PRWHE score independently from the treatment. Our findings suggest that the use of BEF for DRFs with optional KWs can be indicated in both young and elderly patients of any gender, independent of limb side and fracture pattern. As the best functional results were achieved in the elderly when KWs were added, the combination of BEF and KWs seems to be mainly indicated for the treatment of DRF, also complex, in the elderly population.

Effectiveness of surgical versus conservative treatment of distal radius fractures in elderly patients: A systematic review and meta-analysis

BACKGROUND

The aim of this study was to determine whether surgical treatment is more effective than conservative treatment in terms of functional outcomes in elderly patients with distal radius fractures (DRFs).

METHODS

An electronic search of the Medline, Central, Embase, PEDro, Lilacs, CINAHL, SPORTDiscus, and Web of Science databases was performed, from inception until July 2021. The eligibility criteria for selecting studies were randomized clinical trials that compared surgical versus conservative treatment in subjects older than 60 years with DRFs. Two authors independently performed the search, data extraction, and assessed risk of bias (RoB) using the Cochrane RoB tool.

RESULTS

Twelve trials met the eligibility criteria, and nine studies were included in the quantitative synthesis. For volar plate versus cast immobilization at 1-year follow-up, the mean difference (MD) for PRWE was -5.36 points (p=0.02), for DASH was -4.03 points (p=0.02), for grip strength was 8.32% (p=0.0004), for wrist flexion was 4.35 degrees (p=0.10), for wrist extension was -1.52 degrees (p=0.008), for pronation was 2.7 degrees (p=0.009), for supination was 4.88 degrees (p=0.002), and for EQ-VAS was 2.73 points (p=0.0007), with differences in favor of volar plate. For K-wire versus cast immobilization at 12 months, there were no statistically significant differences in wrist range of motion (p>0.05).

CONCLUSIONS

There was low to high evidence according to GRADE ratings, with a statistically significant difference in functional outcomes in favor of volar plate versus conservative treatment at 1-year follow-up. However, these differences are not minimally clinically important, suggesting that both types of management are equally effective in patients older than 60 years with DRFs.

Residual dorsal displacement following surgery in distal radial fractures: A cause for trouble?

PURPOSE

Distal radius fractures have great impact on activities of daily living of affected patients. Repeatedly, a non-anatomic restoration of the volar tilt can be observed in a minimum of 20% in postoperative X-ray control examinations. Hence, the question arises whether the achieved reduction is functionally acceptable, or whether a further attempt should be made to improve the surgical outcome.

METHODS

The data presented here originate from a prospective analysis including three therapy studies on surgical treatment options for fractures of the distal radius between 2004 and 2011. For this study, the participants were divided into two groups: The first group represents the cases with non-anatomical restoration of the volar tilt with - 5° to 5°. The second group contains patients with an anatomical volar tilt between 6° and 15°.

RESULTS

A total of 624 patients were screened according to the inclusion criteria. Radiological evaluation showed consolidation of all fractures. The mean volar tilt as measured in standard x-rays of the wrist was 0° and 8°, respectively. The range of wrist motion in relation of the healthy opposite side was comparable in all directions (for example comparison group 1: Ext/Flex 94/94%; group 2: Ext/Flex 93/93%). Functional assessment of postoperative midterm results employing the Castaing and Gartland & Werley scores 2.3 years after surgery did not reveal significant differences between both groups.

CONCLUSION

According to the available data, a volar tilt in the range of - 5° to 5° can be tolerated intraoperatively without any risk of loss of function regarding the patient's manual abilities.

Long-term clinical and socio-economic outcomes following wrist fracture: a systematic review and meta-analysis

A comprehensive review of studies shows that patients with wrist fracture, aged over 50 years, experience pain and functional limitation long after fracture. This is associated with increased healthcare costs, and reduced quality of life. Understanding factors that predict poor outcomes is important for future healthcare policy and planning.

PURPOSE

To summarise and appraise evidence on the prognosis and long-term clinical and socio-economic outcomes following wrist fracture among adults aged 50 years and over.

METHODS

Five databases (MEDLINE, EMBASE, AMED, CINAHL-P and PsycINFO) were comprehensively searched (supplemented by a grey-literature search) from inception till June 2021 for prospective/retrospective cohort studies of patients (≥ 50 years) with a history of wrist fracture and reporting long-term (≥ 6 months) outcomes. Peer study selection, data extraction and risk of bias assessment were conducted. A random effects meta-analysis was used to summarise estimates of pain and function outcomes.

RESULTS

78 studies (n = 688,041 patients) were included. Patients report persistent moderate to severe pain (range: 7.5%-62%) and functional limitations (range: 5.5-78%) up to 12-months or later after wrist fracture. Mean Patient-Rated Wrist Evaluation (PRWE) score for pain and function (9 studies, n = 1759 patients) was 15.23 (95%CI 12.77, 17.69) at 6-months to 13-years follow-up. Mean disabilities of the arm, shoulder and hand (DASH) score (9 studies, n = 1346 patients) was 13.82 (95%CI 12.71, 14.93)( at 6- to 17-months follow-up. A 10-20% increase in healthcare encounters in the first 12-months after fracture was observed. Twelve prognostic factors were associated with poor long-term outcomes.

CONCLUSION

Evidence shows that a high proportion of people aged over 50 years with wrist fracture experience pain and functional limitation > 6 months after fracture. This is associated with increased healthcare costs, and reduced quality of life. Exploratory evidence was found for several candidate prognostic factors. Their predictive performance needs to be investigated further.

Dorsal Plate Osteosynthesis in Simple and Complex Fractures of the Distal Radius: A Radiological Analysis of 166 Cases

Background  To report the radiologic outcome and rate of complications of open reduction and internal fixation (ORIF) using a dorsal plate fixation of simple and complex distal radius fractures in adult patients. Methods  Patients treated with dorsal ORIF of simple and complex distal radius fractures between December 2008 and April 2013 were included in this single-center retrospective study. Type of fracture, radiographic measurements, and complications were documented. Results  One-hundred and sixty-six patients/fractures were included. Restoration of radial inclination (22° ± 3°) was achieved in 38%. Radial height (14 ± 1 mm) was least likely to be restored to normal values postoperative in 25%. Normal ulnar variance (0.7 ± 1.5 mm) could be observed in 60% and adequate volar tilt (11° ± 5°) was achieved in 50% at final follow-up. We observed one loss of reduction in an AO type C2 fracture and a total of 15 nonimplant-related minor clinical complications. Conclusion  Our radiographic findings after dorsal plating are comparable to those published on volar plating. The changes in radial height and volar tilt could be attributed to projection-related differences in the radiographs and did not signify a loss of reduction in all cases. Clinical Relevance  Dorsal plating of distal radius fractures is safe and remains an important approach in the treatment of complex distal radius fractures. Complications in our study were even less compared to those reported in the literature. Type of Study/Level of Evidence  This is a Type IV study. Level of Experience of Surgeons  The level of experience of surgeons is III-V.

Effectiveness and cost-effectiveness of surgery versus casting for elderly patients with isplaced intra-rticular type C distal adius fractures: protocol of a randomised controlled rial with economic evaluation (the DART study)

INTRODUCTION

Current literature is inconclusive about the optimal treatment of elderly patients with displaced intra-articular distal radius fractures. Cast treatment is less invasive and less expensive than surgical treatment. Nevertheless, surgery is often the preferred treatment for this common type of distal radius fracture. Patients with a non-acceptable position after closed reduction are more likely to benefit from surgery than patients with an acceptable position after closed reduction. Therefore, this study aims to assess non-inferiority of functional outcomes after casting versus surgery in elderly patients with a non-acceptable position following a distal radius fracture.

METHODS AND ANALYSIS

This study is a multicentre randomised controlled trial (RCT) with a non-inferiority design and an economic evaluation alongside. The population consists of patients aged 65 years and older with a displaced intra-articular distal radius fracture with non-acceptable radiological characteristics following either inadequate reduction or redisplacement after adequate reduction. Patients will be randomised between surgical treatment (open reduction and internal fixation) and non-operative treatment (closed reduction followed by cast treatment). We will use two age strata (65-75 and >75 years of age) and a web-based mixed block randomisation. A total of 154 patients will be enrolled and evaluated with the patient-rated wrist evaluation as the primary outcome at 1-year follow-up. Secondary outcomes include the Disabilities of the Arm, Shoulder and Hand questionnaire, quality of life (measured by the EQ-5D), wrist range of motion, grip strength and adverse events. In addition, we will perform a cost-effectiveness and cost-utility analysis from a societal and healthcare perspective. Incremental cost-effectiveness ratios, cost-effectiveness planes and cost-effectiveness acceptability curves will be presented.

ETHICS AND DISSEMINATION

The Research and Ethics Committee approved this RCT (NL56858.100.16). The results of this study will be reported in a peer-reviewed journal. We will present the results of this study at (inter)national conferences and disseminate the results through guideline committees.

Long-term subjective results and radiologic prognosis of a distal radius fracture in working-aged patients - a prognostic cohort study of 201 patients

OBJECTIVE

To investigate long-term outcomes associated with distal radius fracture (DRF) in working-aged patients. The authors hypothesized that the majority of patients experience no permanent loss of function when measured with patient-rated wrist evaluation (PRWE).

METHODS

This was a retrospective cohort study of patients with a DRF aged between 18 and 65 years. The primary outcome measure was PRWE score at a minimum of 4 years after DRF. Secondary outcome measures were pain catastrophizing scale (PCS) and radiographic measurements.

RESULTS

Of 201 patients included, 179 were primarily treated non-operatively with a 5-week cast treatment and 22 were primarily operated. The mean follow-up duration was 5 years. The mean PRWE score was 10.9 (95% confidence interval 8.4, 13.4) and median PRWE was 3.5 (interquartile range, 0.0-13.0). There was minor correlation between PCS and PRWE score (correlation coefficient [CC] 0.3), and between PRWE score and dorsal angulation of the fracture measured after closed reduction (CC 0.2) and in one-week follow-up radiographs (CC 0.2).

CONCLUSIONS

Working-aged patients seem to gain nearly normal wrist function after DRF in longer follow-up. Pain catastrophizing appears to correlate with long-term treatment outcome.

A post-surgical rehabilitation program for women over 60 years old who underwent surgery in trauma and orthopedic hospital after distal radius fracture

INTRODUCTION

Distal radius fractures (DRFs) are associated with a high economic burden and an impact on quality of life on these patients. Its high prevalence demonstrates the importance of registering functional results, with emphasis on vulnerable population such as elderly females.

METHODS

Thirty-six patients were admitted to a multimodal rehabilitation program. Exercise progressions combined with manual therapy and electrophysical agents were provided, taking into account bone and soft tissues healing stages, protection of surgical intervention and symptoms of each patient. The primary outcome was the Patient Rated Wrist Evaluation (PRWE) questionnaire. The secondary outcomes were wrist and forearm range of motion (ROM), grip strength and lateral and tripod pinch strength. The paired t-test was used to compare mean PRWE, ROM, and strength between 6 and 12 weeks.

RESULTS

An improvement of functionality was observed with a decreased of -20.9 (CI 95%: 25.9 to -15.9) points in the PRWE questionnaire (p < 0.001) between 6 and 12 weeks after DRF surgery. In addition, an increase in the ROM of the wrist (p < 0.001), grip strength (p < 0.001), lateral pinch (p < 0.001) and tripod pinch (p < 0.001) were observed between 6 and 12 weeks after surgery.

CONCLUSIONS

These findings showed a clinically and statistically significant improvement in function, ROM, and strength assessed at weeks 6 and 12 after surgery. However, this study design cannot establish a cause-and-effect relationship. Future randomized controlled clinical trials should investigate the effectivity of similar rehabilitation programs.

Is there a correlation between functional results and radiographic findings in patients with distal radius fracture A0 type A3 treated with volar locking plate or external fixator?

The aim of this study was to test the hypothesis that precise restoration of distal radius fractures is correlated to better patient-reported outcome.

METHODS

The correlation between radiographic results and functional outcome was explored in 156 patients with extra-articular distal radius fractures included in a multicenter, randomized controlled trial comparing 2 surgical interventions, Volar Locking Plate or External Fixator. The primary functional outcome was the Patient Rated Wrist and Hand Evaluation score (PRWHE). Radiographically we assessed volar tilt, radial inclination, radial height, ulnar variance, and the presence of ulnar styloid fracture. The Pearson correlation analysis was used to estimate correlations between parameters.

RESULTS

At 1-year follow-up the mean difference in radiographic findings compared with the uninjured side (min, max) was: reduced volar tilt 5.3° (-15°, 25°), reduced radial inclination 2.3° (-6°, 12°), radial height 1.3 mm (-4 mm, 7 mm), and ulnar variance -0.5 mm (-6 mm, 3 mm). Overall, we found no correlation between radiographic parameters and the PRWHE at 1-year follow-up within the whole group, regardless of which treatment was chosen. At the time of injury 53% (N = 80) had sustained an additional ulnar styloid fracture. After 1 year this fracture was still radiographically present in 31% (N = 43) of the patients. No correlation between PRWHE score and the presence of an ulnar styloid fracture at 1-year follow-up was found.

CONCLUSIONS

We found no correlation between functional outcome (PRWHE) and radiographic findings after 1 year in patients operated on with a Volar Locking Plate or External Fixator. Patient-specific factors were more important than radiographic measurements in this study group.Level of evidence: Therapeutic Level 2Trial registration: Norway: National Committee for Medical and Health Research Ethics 213/555ClinicalTrials.gov ID: NCT01904084Randomization of first patient: 02.09.2013.

Patient-Perceived Outcomes After Nonoperative Treatment of Distal Radius Fracture in Older Adults

Malunion after distal radius fracture is common in older patients; however, whether patient-perceived outcomes are influenced by radiologic outcome is controversial. This study evaluated patient-perceived outcomes according to radiologic parameters in older patients who underwent nonoperative treatment. The records of 167 patients older than 55 years who had a distal radius fracture were reviewed. All fractures were treated nonoperatively, and average length of follow-up was 7 years. Outcomes were evaluated using numeric rating scales for pain and satisfaction, as well as Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores. Radiographs were evaluated for dorsal tilt, radial inclination, and ulnar variance. Fifty-one patients (30%) developed malunion. The pain numeric rating scale score was 0.8 for patients with malunion and 0.4 for patients with acceptable alignment; this difference was not statistically significant. The QuickDASH score was higher for patients with malunion (14.9 vs 11.1 for patients with acceptable alignment); however, this difference was not clinically meaningful. Satisfaction scores were lower for patients with malunion than for patients with acceptable alignment (80.8 vs 92.3). Patients with malunion stated they would choose surgery rather than a cast (13.3% vs 7.2%) if they developed another fracture; this difference was not statistically significant. The subanalysis according to radiologic parameters showed dorsal tilt and ulnar variance affected patient satisfaction but not other outcomes. This study indicated nonoperative treatment in older adults obtained acceptable patient-perceived outcomes despite residual deformity. However, patients whose radiologic parameter exceeded the tolerable range were less satisfied. [Orthopedics. 2021;44(2):e190-e196.].

Outcomes and complications of operative versus non-operative management of distal radius fractures in adults under 65 years of age

To compare the outcomes of non-operative versus operative treatment for distal radius fractures in patients aged from 18 to 64 years, we performed a retrospective analysis using the OptumLabs® Data Warehouse using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis codes of distal radius fracture. Of the 34,184 distal radius fractures analysed, 11,731 (34%) underwent operative management. Short-term complications within 90 days of fracture identified an overall complication rate of 16.6 per 1000 fractures and the 1-year upper extremity-specific complication rate was 287 per 1000 fractures. Overall, post-injury stiffness was the most common 1-year upper extremity-specific complication and was associated with operative management (202.8 vs. 123.4 per 1000 fractures, operative vs. non-operative, p < 0.01). Secondary procedures were significantly more common following non-operative management (8.7% vs. 43%, operative vs. non-operative, p < 0.01) with carpal tunnel release representing the most common secondary procedure. Operative management of distal radius fractures resulted in significantly fewer secondary procedures at the expense of increased overall 1-year complication rates, specifically stiffness.Level of evidence: III.

Volar Locking Plate Fixation Versus Closed Reduction for Distal Radial Fractures in Adults: A Systematic Review and Meta-Analysis

BACKGROUND

Distal radial fractures in adults are common, representing a substantial burden to patients and health systems. The 2 main treatments are closed reduction and cast immobilization (CR) and volar locking plate (VLP) fixation. Our primary aim was to determine if VLP fixation leads to better patient-reported pain and function at 12 months compared with CR.

METHODS

We searched systematically for randomized controlled trials (RCTs) comparing outcomes of VLP fixation with CR for the treatment of distal radial fractures in adults. The Cochrane Collaboration risk-of-bias tool was used to assess the methodological quality of each study. Meta-analyses of patient-reported outcomes, clinical outcomes, and complications were performed. Key findings were assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.

RESULTS

A total of 8 RCTs (810 participants) were eligible for inclusion. Based on moderate-certainty evidence, no clinically important differences in patient-reported pain and function were found: although the mean difference (MD) in the Disabilities of the Arm, Shoulder and Hand (DASH) score at 12 months was 4.1 points (95% confidence interval [CI], 1.2 to 7.0 points) in favor of VLP fixation, this was well below the minimum clinically important difference of 10 points. There was low-certainty evidence that VLP fixation led to better Patient-Rated Wrist Evaluation (PRWE) scores at 12 months (MD, 6.9 points; 95% CI, -0.6 to 14.3 points) and better DASH scores at 24 months (MD, 8.9 points; 95% CI, 5.8 to 12.1 points) but again, these differences were not clinically important. There was very low or low-certainty evidence that VLP fixation provided better long-term radiographic outcomes, including palmar tilt (MD, 6.5°; 95% CI, 2.8° to 10.1°), radial inclination (MD, 3.4°; 95% CI, 2.5° to 4.3°), and ulnar variance (MD, 0.7 mm; 95% CI, -0.8 to 2.1 mm).

CONCLUSIONS

There were no clinically important differences between treatments with respect to patient-reported pain and function at 12 months post-treatment, even though VLP fixation resulted in better fracture alignment than CR.

Patient-related outcome, fracture displacement and bone mineral density following distal radius fracture in young and older men

BACKGROUND

Distal radius fractures can adversely affect wrist function; for men with this fracture, the role played by fracture severity, age and osteoporosis on fracture outcome has not been sufficiently studied.

OBJECTIVE

To describe patient-reported outcome and the association with bone integrity, fracture severity and future fracture risk among young and older men with distal radius fracture.

METHODS

This prospective study includes 133 men with acute distal radius fracture, mean age 54 (range 21-88), who were followed for 12 months. They were categorized as younger (< 65) and older (65+). Main outcome was DASH (Disability of the Arm, Shoulder and Hand) at 12 months; DASH > 15 was defined as poor outcome. Fractures were classified and radiographic displacement identified at initial presentation and follow-up. BMD was measured and FRAX 10-year probability of fracture calculated.

RESULTS

Disability was higher in older men (DASHmedian 10 vs 2; p = 0.002); a clinically meaningful difference (ΔDASH = 10, p = 0.017) remained after adjustment for displacement, fracture classification and treatment method. Almost 50% of older men vs 14% in younger had poor outcome, p < 0.001. Bone mineral density did not independently predict outcome. Older men with a displaced fracture at initial presentation had greater disability (DASHmedian, IQR 45, 14;73) and risk of fracture (FRAXmajor osteoporotic 14, 8;21).

CONCLUSION

Men over the age of 65 with a distal radius fracture are more likely to have post-fracture disability regardless of radiographic appearance. Fracture displacement, indicating impaired bone strength, is also more common and associated with an increased risk of fracture within 10-years. Secondary fracture prevention should therefore be considered in men presenting with distal radius fracture.

Manual ability in hand surgery patients: Validation of the ABILHAND scale in four diagnostic groups

Background

Patients treated in hand surgery (HS) belong to different demographic groups and have varying impairments related to different pathologies. HS outcomes are measured to assess treatment results, complication risks and intervention reliability. A one-dimensional and linear measure would allow for unbiased comparisons of manual ability between patients and different treatment effects.

Objective

To adapt the ABILHAND questionnaire through Rasch analysis for specific use in HS patients and to examine its validity.

Methods

A preliminary 90-item questionnaire was presented to 216 patients representing the diagnoses most frequently encountered in HS, including distal radius fracture (n = 74), basal thumb arthritis (n = 66), carpal tunnel syndrome (n = 53), and heavy wrist surgery (n = 23). Patients were assessed during the early recovery and in the late follow-up period (0–3 months, 3–6 months and >6 months), leading to a total of 305 assessments. They rated their perceived difficulty with queried activities as impossible, difficult, or easy. Responses were analyzed using the RUMM2030 software. Items were refined based on item-patient targeting, fit statistics, differential item functioning, local independence and item redundancy. Patients also completed the QuickDASH, 12-item Short Form Survey (SF-12) and a numerical pain scale.

Results

The rating scale Rasch model was used to select 23 mostly bimanual items on a 3-level scale, which constitute a unidimensional, linear measure of manual ability with good reliability across all included diagnostic groups (Person-Separation Index = 0.90). The resulting scale was found to be invariant across demographic and clinical subgroups and over time. ABILHAND-HS patient measures correlated significantly (p<0.001) with the QuickDASH (r = -0.77), SF-12 Physical Component Summary (r = 0.56), SF-12 Mental Component Summary (r = 0.31), and pain scale (r = -0.49).

Conclusion

ABILHAND-HS is a robust person-centered measure of manual ability in HS patients.

Comparison of outcomes between nonsurgical and surgical treatment of distal radius fracture: a systematic review update and meta-analysis

INTRODUCTION

This study was a systematic review comparing the clinical outcomes of nonsurgical and surgical management for distal radius fractures.

MATERIALS AND METHODS

A comprehensive literature search was conducted using multiple databases, including Medline, Embase, and Cochrane. All databases were searched from the earliest records through June 2019 using the following Boolean operators: distal radius fracture, conservative treatment, nonoperative treatment, nonsurgical treatment, surgical treatment, and operative. All prospective and retrospective controlled trials were retrieved that directly compared the functional outcomes between the nonsurgical and surgical groups.

RESULTS

Five prospective studies and six retrospective comparative studies were retrieved. A total of 1049 patients were included: 529 in the nonsurgical group and 520 in the surgical group. Both types of treatment led to similar results with respect to DASH and grip strength, as well as and most other functional assessments. However, there was significant difference in radial inclination, radial length, ulnar variance and range of wrist flexion.

CONCLUSIONS

No significant differences in most functional assessments were found when comparing surgical and nonsurgical management of distal radius fractures. Although there were significant differences in radial inclination, radial deviation, ulnar variance, and wrist flexion, they did not seem to have impacts on the quality of wrist. Nonsurgical treatment for the distal radius fractures should be considered firstly. Indications for operative fixation should be considered carefully in the treatment of DRFs.

Radiological results of surgical management of fracture of the distal radius treated with volar locking plates

OBJECTIVES

Distal radius fracture (DRF) is the most common upper extremity fracture. The incidence of complications after surgical treatment still remains high. The objective of our study was to assess functional and radiological results of DRF treated with volar locking plate.

METHODS

We conducted a retrospective study including DRF treated by open reduction and internal fixation with a volar locking plate during a period of 8 years (2010-2018). Data were collected from clinical records and included patient demographics, fracture characteristics, radiological parameters (radial inclination, palmar tilt, ulnar variance, articular step-off), range of motion (ROM), complications and reinterventions.

RESULTS

A total of 170 patients (63.5% female) met the inclusion criteria with a mean age of 55.9 years [24.1-83.7; 13.76]. High energy injuries were more frequent in younger patients (25.56% vs 3.95%; p < 0.0001). AO classification was: 2R3A: 23.5%, 2R3B: 24.1% and 2R3C: 52.4%. Time until surgery was 8.5 days, longer in extraarticular fractures (AO-2R3A: 12.22 days, AO-2R3B: 7.97 days, AO-2R3C: 7.04 days, p = 0.018). Younger patients had better radial inclination (excellent in 85.1% vs 59.21%, p = 0.001) and radial shortening (excellent in 100% vs 88.15%, p = 0.001). ROM was: flexion 63° [0-90°; 19.73], extension 57.67° [5-90°; 21.61], pronation 78.94° [40-90°] and supination 81.76° [38-90°; 8.87]. We found a weak correlation between ROM in flexion-extension and radial shortening (r = 0.218; p = 0.001) and articular step-off (r = -0.269; p = 0.002). We had 39 complications (21.18% of patients). 10.6% of patients needed a re-operation, being the most frequent hardware removal (6.5%) and tendinous disruptions repairs (2.4%). Reintervention rate was higher in younger patients (14.9% vs 5.3%; p = 0.042), complete articular fractures (AO-2R3A: 2.5%; AO-2R3B: 7.3%; AO-2R3C: 15.7%; p = 0.037) and high energy injuries (8.4% vs 22.2%; p = 0.044). Patients undergoing reintervention had a decreased flexion-extension (94.44° vs 123.83°, p = 0.007).

CONCLUSION

Radial shortening and articular step-off seem the most important predictors for postoperative range of motion. Worse radiological outcomes are observed in complete articular fractures and those affecting elder population. Although radiological and functional results are good or excellent in most of cases, the incidence of complications and need for reintervention still remains noticeable. Re-operations were more frequent in younger patients, complete articular fractures and high energy injuries, and it worsened functional outcomes.

Deterioration of initially accepted radiological alignment of conservatively treated AO type-C distal radius fractures: mid-term outcome

BACKGROUND AND AIMS

It still remains controversial how often the once-accepted radiological alignment of an AO type-C distal radius fracture deteriorates after conservative treatment, and to what extent this deterioration is perhaps associated with patient-rated outcome measures (PROms). Thus, we aimed to evaluate this radiological deterioration and its association with mid-term functional follow-up.

PATIENTS AND METHODS

We retrospectively reviewed 66 patients (mean age at fracture 53 years, SD 14.1, range 18-73, female 65%) with 68 C-type distal radius fractures at a mean of 6.7 years (SD 0.5 years, range 5.8-7.7 years) after primary closed reduction and cast immobilization. Radiographs of the wrists were taken and analysed for any radial shortening, dorsal tilt or step-off at the joint surface. Range of motion and grip strength were measured. In addition to the radiological result, primary outcome measures included Quick Disabilities of the Arm, Shoulder and Hand (QDash) and Patient-Rated Wrist Evaluation (PRWE).

RESULTS

At mid-term follow-up, an acceptable anatomical radiological result was seen in only 22 wrists (32%). Deterioration of the once-achieved and accepted primary alignment was seen in a majority of cases (68%). Radial shortening of ≥ 2 mm was found in 34 wrists (51%, mean 4 mm, range 2-8 mm), with no association with QDash (12.8 vs. 5.5, p = 0.22) or PRWE (9.1 vs. 5.7, p = 0.40). Only four patients (6%) showed step-off at the joint surface (mean 1.1 mm, range 0.5-2 mm). Twenty-two wrists (32%) showed dorsal tilt of ≥ 10° (five with volar tilt of 15°-25°), with no effect on QDash or PRWE (14.7 vs. 6.5, p = 0.241 and 10.1 vs. 5.8, p = 0.226). Altogether, patients with dorsal tilt, step-off or shortening did not show significantly worse QDash (10.3 vs. 5.7, p = 0.213) or PRWE (8.1 vs. 5.1, p = 0.126) versus those with none. Twenty-nine (43%) of the patients had deficits in range of motion (ROM), either in extension (39%), flexion (43%), supination (16%) or pronation (4%), or combinations of these. Worse extension was associated with worse QDash (15.9 vs. 5.0, p = 0.037), flexion deficit with worse PRWE (11.5 vs. 4.4, p = 0.005) and supination deficit with both QDash (21.7 vs. 6.8, p = 0.025) and PRWE (18.9 vs. 5.2, p = 0.007).

CONCLUSIONS

The initially accepted radiological alignment of AO type-C radius fractures deteriorated in a majority of cases during conservative treatment. However, this deterioration was fairly mild and showed no significant association with functional outcome. Restricted ROM showed some association with PROms.

Assessment of Anatomic Restoration of Distal Radius Fractures Among Older Adults: A Secondary Analysis of a Randomized Clinical Trial

IMPORTANCE

The value of precise anatomic restoration for distal radius fractures (DRFs) in older adults has been debated for many decades, with conflicting results in the literature. In light of the growing population of adults aged 60 years and older, both fracture incidence and associated treatment costs are expected to increase.

OBJECTIVE

To determine the association between radiographic measures of reduction and patient outcomes after DRF in older patients.

DESIGN, SETTING, AND PARTICIPANTS

Data were collected from the Wrist and Radius Injury Surgical Trial (WRIST), a multicenter randomized clinical trial of DRF treatments for adults aged 60 years and older (enrollment from April 10, 2012, to December 31, 2016, with a 2-year follow-up). Data analysis was performed from January 3, 2019, to August 19, 2019. WRIST participants who completed 12-month assessments were included in the study. According to the biomechanical principle of alignment, 2-phase multivariable regression models were adopted to assess the association between radiographic measures of reduction and functional and patient-reported outcomes 12 months following treatment.

INTERVENTIONS

Participants were randomized to receive volar locking plate, percutaneous pinning, or external fixation. Those who opted for nonoperative treatment received casts.

MAIN OUTCOMES AND MEASURES

Hand grip strength, wrist arc of motion, radial deviation, ulnar deviation, the Michigan Hand Outcomes Questionnaire (MHQ) total score, MHQ function score, and MHQ activities of daily living score were measured at 12 months following treatment.

RESULTS

Data from 166 WRIST participants (144 [86.7%] women; mean [SD] age, 70.9 [8.9] years) found that only 2 of the 84 correlation coefficients calculated were statistically significant. For patients aged 70 years or older, every degree increase in radial inclination away from normal (22°) grip strength in the injured hand was 1.1 kg weaker than the uninjured hand (95% CI, 0.38-1.76; P = .004) and each millimeter increase toward normal (0 mm) in ulnar variance was associated with a 10.4-point improvement in MHQ ADL score (95% CI, -16.84 to -3.86; P = .003). However, neither of these radiographic parameters appeared to be associated with MHQ total or function scores.

CONCLUSIONS AND RELEVANCE

The study results suggest that precise restoration of wrist anatomy is not associated with better patient outcomes for older adults with DRF 12 months following treatment. Surgeons can consider this evidence to improve quality of care by prioritizing patient preferences and efficient use of resources over achieving exact realignment.

Correlation Between Radiological Parameters and Functional Outcomes in Patients Older Than 60 Years of Age With Distal Radius Fracture

Background: The relationship between radiographic and functional outcomes is controversial in the elderly. The objective of this study is to determine whether there is a correlation between functional outcome and acceptable distal radius fracture (DRF) alignment in patients older than 60 years of age. Methods: This correlation study was carried out at the Central Metropolitan Health Service of Chile. A total of 180 patients diagnosed with extra-articular DRF, according to the AO classification, were prospectively recruited. Radiological parameters, including radial inclination, residual dorsal angulation, ulnar variance, and articular step-off, were evaluated to assess the results of orthopedic reduction. Functional outcome was assessed immediately following cast removal and again at the 6-month follow-up. The Disabilities of the Arm, Shoulder and Hand (DASH) and Patient-Rated Wrist Evaluation (PRWE) questionnaires were administered to assess upper extremity function, and the visual analog scale (VAS) was used to assess pain intensity. Results: Only 68 patients (37.8%) showed acceptable DRF alignment. After cast removal, the correlations between alignment and the functional outcome measures were as follows: DASH 0.071 (P = .546), PRWE 0.03 (P = .823), and VAS 0.12 (P = .631). At the 6-month follow-up, the correlations between alignment and the functional outcome measures were as follows: DASH 0.029 (P = .768), PRWE 0.014 (P = .895), and VAS 0.09 (P = .614). Conclusions: There was no significant correlation between acceptable alignment according to radiological parameters and short- or medium-term functional outcome in patients older than 60 years with extra-articular DRF treated conservatively.

International Survey: Factors Associated With Operative Treatment of Distal Radius Fractures and Implications for the American Academy of Orthopaedic Surgeons' Appropriate Use Criteria

OBJECTIVES

Through an international survey, we assessed whether deciding to operatively treat an intra-articular distal radius fracture (DRF) is guided by identifiable patient and surgeon factors. In addition, we compared surgeons' treatment decisions with the American Academy of Orthopaedic Surgeons' Appropriate Use Criteria (AUC) treatment recommendations.

METHODS

This cross-sectional survey asked 224 surgeons to operatively or nonoperatively treat 28 hypothetical patients with radiographs of an intra-articular DRF. We randomized patient age (50/70 years), gender, mechanism of injury, activity level, and OTA/AO fracture type. We classified 6 fractures as "nonclinically significant displacement" and 22 as "potentially clinically significant displacement." Multilevel logistic regression analysis was performed. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. Statistical significance was P < 0.05.

RESULTS

Patient factors independently associated with surgery included younger age (OR 6.7, P = 0.003), clinically significant fracture displacement (type B: OR 122, CI, 20-739, P < 0.001; type C: OR 59, CI, 12-300, P < 0.001), normal activity level (OR 5.0, P < 0.001), and high-energy mechanisms (OR 1.3, P = 0.002). Surgeon factors associated with recommending surgery included practicing outside the United States (Europe: OR 2.6, P < 0.001; "other": OR 4.8, P < 0.001). Hand surgeons most often selected surgery, as compared to orthopaedic trauma surgeons (OR 2.3, P = 0.001) and "other orthopaedists" (OR 2.2, P = 0.022). Thirty-seven percent of treatment decisions for patients with normal activity levels were rated by AUC recommendations as "rarely appropriate," which included 91% disagreement for 70-year-olds with nonclinically significant displacement.

CONCLUSIONS

Surgeons use patient age and fracture displacement to make treatment recommendations for intra-articular DRF. We recommend that the AUC be updated to include these clinical factors as essential components in its algorithm.

Considerations in the Treatment of Osteoporotic Distal Radius Fractures in Elderly Patients

PURPOSE OF REVIEW

With the incidence of distal radius fractures increasing in the elderly population, we sought to summarize the current orthopedic and medical management of these fractures in the elderly osteoporotic population.

RECENT FINDINGS

The number of osteoporotic patients undergoing surgical fixation for distal radius fractures has increased in recent years. This is likely due to the improved outcomes seen with volar locking plates, as well as an increase in the number of fellowship-trained hand surgeons. Despite this potential improvement in acute fracture management, a majority of these patients are underdiagnosed and undertreated for their underlying osteoporosis or endocrinopathies. The implementation of fracture liaison services and the ability of the treating orthopedist to recognize this gap in patient care result in a higher number of patients initiating appropriate treatment. It is vital that when discussing acute fracture management, a thorough discussion is had with patients regarding functional outcome and the benefits of both surgical and non-operative management. As these fractures become more prevalent and a greater percentage undergo surgical intervention, the economic burden of distal radius fractures will continue to rise. It is imperative that the treating surgeon view these fractures as sentinel events that are predictive of future hip and vertebral fractures. While relatively new, the use of fracture liaison services to help aide in proper screening and treatment of osteoporotic patients is of great value. Non-pharmacologic therapy such as physical therapy, smoking and alcohol cessation programs, and dietary modifications are crucial in treating patients with osteoporosis. While bisphosphonates remain the first-line treatment in patients with osteoporosis, novel therapies show promise for future use.

Assessment of Distal Radius Fracture Complications Among Adults 60 Years or Older: A Secondary Analysis of the WRIST Randomized Clinical Trial

IMPORTANCE

Complications affect treatment outcomes and quality of life in addition to increasing treatment costs.

OBJECTIVES

To evaluate complication rates after the treatment of a distal radius fracture, to determine whether the rate or complication type is associated with treatment method, and to determine predictors of complications.

DESIGN, SETTING, AND PARTICIPANTS

The multicenter Wrist and Radius Injury Surgical Trial (WRIST), a randomized clinical trial, enrolled participants from April 10, 2012, to December 31, 2016. The study included 304 adults 60 years or older with isolated unstable distal radius fractures; 187 were randomized and 117 opted for casting. The study was conducted at 24 health systems in the United States, Canada, and Singapore. Data for this secondary analysis were collected from April 24, 2012, to February 28, 2018.

INTERVENTIONS

Participants opting for surgery were randomized to receive the volar locking plate system (n = 65), percutaneous pinning (n = 58), or bridging external fixation with or without supplemental pinning (n = 64). Patients who chose not to have surgery (n = 117) were not randomized and were enrolled for casting.

MAIN OUTCOMES AND MEASURES

Complication rate.

RESULTS

The WRIST enrolled a total of 304 participants, of whom 8 casting group participants were later found to be ineligible and were excluded from the analysis, leaving 296 participants. Randomized participants' mean (SD) age was 68 (7.2) years, 163 (87%) were female, and 165 (88%) were white. Casting participants' mean (SD) age was 75.6 (9.6) years, 93 (84%) were female, and 85 (85%) were white. The most common type of complications varied by treatment. Twelve of 65 participants (18.5%) in the internal fixation group reported a median nerve compression, while 16 of 26 participants (25.8%) who received external fixation and 13 of 56 participants (23.2%) who received pinning sustained pin site infections. Compared with the internal fixation group, complication rate for any severity complication was higher in participants who initially received casting (adjusted rate ratio, 1.88; 95% CI, 1.22-2.88), whereas the rate for moderate complications was higher in the external fixation group (adjusted rate ratio, 2.52; 95% CI, 1.25-5.09).

CONCLUSIONS AND RELEVANCE

The distal radius fracture treatment decision-making process for older patients should incorporate a complication profile for each treatment type. For example, external fixation and pinning could be used for patients after apprising them of pin site infection risk. Internal fixation can be done in patients with high functional demands who are willing to receive surgery. Internal fixation use should be substantiated owing to the time and cost involved.

Cast immobilization versus volar locking plate fixation of AO type C distal radial fractures in patients aged 60 years and older

Objective

The aim of this study was to evaluate the efficacy of conservative treatment (cast immobilization) for complex intra-articular distal radius fractures (AO type C) in elderly patients and to determine whether or not the application of a volar locking plate (VLP) is necessary.

Methods

A retrospective study on patients treated at two different clinics was conducted between 2014 and 2016. A total of 49 elderly patients ≥60 years old were treated either operatively with volar locking plate fixation (n = 25; 7 males and 18 females; mean age: 66.6 ± 7.4 years) or conservatively with cast immobilisation (n = 24; 7 males and 17 females; mean age: 68.9 ± 8.7 years) for complex intra-articular distal fractures. Clinical, functional and radiological evaluations were conducted at the final follow-up examinations of the patients.

Results

There was no statistically significant difference between the two groups of patients with respect to the follow-up periods, gender, age and fracture type (p > 0.05). At the end of mean follow-up time of 16 months the grip strength (p = 0.03), radial tilt (p = 0.06), radial inclination (p = 0.01), radial height (p = 0.01) and articular step-off (p = 0.02) were significantly better in the volar locking plate group, while there was no significant difference between the functional results (based on the Quick Disabilities of the Arm, Shoulder and Hand score) (p = 0.8) and range of motion. The grip strength was significantly higher in the VLP group when compared to the cast group (p = 0.03).

Conclusion

The results of this study suggest that the locking plate fixation for the complex intra-articular distal radius fractures provides better results for the grip strength and radiographic parameters than cast immobilization in patients ≥60 years old, while no difference was found between the clinical and functional results.

Evidence-based management of patients with Colles' fractures in emergency departments: a case-based critical reflection

Distal forearm fractures are a common presentation in UK emergency departments (EDs). However, despite the frequency of this presentation there is considerable variation in management, which may reflect the lack of definitive evidence to support one method. This article provides a narrative review of the literature on these injuries and provides an evidence-based approach to how they can be managed by ED clinicians.

Use of a 5-Item Modified Frailty Index for Risk Stratification in Patients Undergoing Surgical Management of Distal Radius Fractures

PURPOSE

Compared with cast treatment, surgery may expose patients with distal radius fractures to undue risk. Surgical intervention in this cohort may offer less benefit than previously thought and appropriate patient selection is imperative. The modified Frailty Index (mFI) predicts complications after other orthopedic surgeries. We hypothesized that this index would predict, and might ultimately prevent, complications in patients older than 50 years with distal radius fractures.

METHODS

We retrospectively reviewed the American College of Surgeons-National Surgery Quality Improvement Program (ACS-NSQIP) database, including patients older than 50 years who underwent open reduction and internal fixation of a distal radius fracture. A 5-item mFI score was then calculated for each patient. Postoperative complications, readmission and reoperation rates, as well as length of stay (LOS) were recorded. Bivariate and multivariable statistical analysis was then performed.

RESULTS

We identified 6,494 patients (mean age, 65 years). Compared with patients with mFI of 0, patients with mFI of 2 or greater were nearly 2.5 times as likely to incur a postoperative complication (1.7% vs 7.4%). Specifically, the rates of Clavien-Dindo IV, wound, cardiac, and renal complications were increased significantly in patients with mFI of 2 or greater. In addition, as mFI increased from 0 to 2 or greater, 30-day reoperation rate increased from 0.8% to 2.4%, 30-day readmission from 0.8% to 4.6%, and LOS from 0.5 days to 1.44 days. Frailty was associated with increased complications as well as rates of readmission and reoperation even when controlling for demographic data, LOS, and operative time. Age alone was not significantly associated with postoperative complications, readmission, reoperation, or LOS.

CONCLUSIONS

A state of frailty is highly predictive of postoperative complications, readmission, reoperation, and increased LOS following open reduction and internal fixation of distal radius fractures. Our data suggest that a simple frailty evaluation can help inform surgical decision making in patients older than 50 years with distal radius fractures.

Association Between Radiological and Patient-Reported Outcome in Adults With a Displaced Distal Radius Fracture: A Systematic Review and Meta-Analysis

PURPOSE

To evaluate the association between alignment, as determined by plain radiographs, and patient-reported outcome in adults with a displaced distal radius fracture. We also determined which specific radiological parameters are associated with patient-reported outcomes.

METHODS

We performed a systematic literature search to identify studies that evaluated the association between radiological and patient-reported outcome in adults with a displaced distal radius fracture and who had an average follow-up of at least 12 months. Radiological outcome was determined as acceptable or unacceptable reduction, defined by radiological parameters. Patient-reported outcome was assessed with the Disability of the Arm, Shoulder, and Hand, the Quick-Disability of the Arm, Shoulder, and Hand, and the Patient-Rated Wrist Evaluation questionnaires.

RESULTS

Sixteen articles were included, comprising 1,961 patients with a distal radius fracture. A significant mean difference of 4.15 points in patient-reported outcomes (95% confidence interval [CI], 0.26-8.04) was found in favor of an acceptable radiological reduction. Moreover, a significant mean difference of 5.38 points in patient-reported outcomes (95% CI, 1.69-9.07) was found in favor of an acceptable dorsal angulation, and 6.72 points (95% CI, 2.16-11.29) in favor of an acceptable ulnar variance.

CONCLUSIONS

An unacceptable radiological reduction is significantly associated with worse patient-reported outcomes in adults with a displaced distal radius fracture. Dorsal angulation and ulnar variance are the most important radiological parameters. Despite the statistical significance, the mean difference of each association did not meet the threshold of the minimally clinically important difference and therefore were unlikely to be clinically important.

Functional range of motion in the metacarpophalangeal joints of the hand measured by single axis electric goniometers

BACKGROUND

The functional range of motion (fROM) of the metacarpophalangeal (MCP) joints during the performance of activities of daily living (ADL) has not yet been established. This study aimed to determine the fROM of all five digits and verify the accuracy and reproducibility of dynamic angle measurement using a single-axis electric goniometer (EG) during ADL movements of the hand.

METHODS

This was a cross-sectional study. In EG suitability testing, we first confirmed the angles of a three-dimensional calibration device 10 times, and then compared EG readings with those determined by tomosynthesis images. Next, we determined the fROM of the MCP joints by evaluating all five digits of the dominant hands of 10 healthy adults performing 16 ADL. Intra-rater reproducibility of MCP joint data during task performance was assessed in two healthy adults.

RESULTS

Static measurements of the triangular object showed variance to be within one degree in 39 of 40 trials. Differences between angles measured by the EG and those depicted by radiograph were a range of plus or minus five degrees in 88 of 96 digits. The fROM values for the thumb and index, middle, ring, and little fingers were -7.5 to 35.3, 10.6 to 67.8, 4.0 to 79.9, 3.0 to 83.9, and 2.9-91.4 degrees of flexion, respectively. Flexion angle in the fROM of the index finger was significantly smaller than those of the ring and little fingers. The flexion and extension angles of the thumb were significantly smaller than those of the four ulnar fingers. The intra-rater correlation coefficients of two participants were high at 0.94 and 0.93, respectively.

CONCLUSIONS

The method adopted in this study exhibited excellent accuracy and reproducibility and was therefore considered suitable for the real-time establishment of fROM flexion-extension angles of the MCP joints for all five digits. Our data are useful as a target arc of motion in the treatment of MCP joint disease or injury.

Distal Radius Fractures: AAOS Appropriate Use Criteria Versus Actual Management at a Level I Trauma Center

BACKGROUND

The aim of this study is to determine whether the American Academy of Orthopaedic Surgeons' (AAOS) Appropriate Use Criteria (AUC) for distal radius fractures correlates with actual treatment by orthopedic hand surgeons at a level I trauma center.

METHODS

ICD-9 codes were used to retrospectively identify patients who presented with wrist fractures over 1 year. Patients with isolated distal radius fractures were evaluated using the AAOS AUC application for distal radius fractures. Actual treatment was then compared with treatment recommended by the AUC.

RESULTS

Of the 112 patients, 64 (57%) received treatment that matched the AAOS AUC recommendation as an "appropriate treatment." Actual management matched the AUC recommendation 100%, 7%, and 50% of the time, for Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) type A, B, and C fractures, respectively. Surgery was performed for type A, B, and C fractures 30%, 7%, and 50% of the time, respectively. For type B fractures, only the 2 cases that were managed operatively were in agreement with the AUC. For type C fractures, increased patient age (57 years and older) was significantly associated with nonoperative treatment decisions. Surgeon decisions for nonoperative treatment were in agreement with the AUC recommendations 40% of the time, whereas surgeon decisions for surgery matched the AUC recommendations 97% of the time.

CONCLUSIONS

We found low agreement between actual treatment decisions and the AUC-recommended "appropriate" treatments, especially for the type B and C fractures that were managed nonoperatively. The AUC favors surgery for all intra-articular fractures, while we emphasized age and fracture displacement in our decision-making process.

Conservative treatment of distal fractures after the age of 65: a review of literature

The goal of this study was to evaluate the role of conservative treatment of distal radius fractures in the elderly since 2000. Our series included 22 articles, of which 3 reviews, 2 meta-analyses, 6 descriptive series of conservative treatment, 10 series comparing surgical and conservative treatments and 1 series comparing different types of conservative treatments. The reduction was performed by closed reduction in 7 cases and by traction in 3 cases. A short-arm cast was used in 8 cases and a long-arm cast in 4 cases for an average length of 6 weeks. The indications of conservative treatment were varied: AO type A fractures in 2 cases, type C fractures in 1 case, types A and C in 8 cases and types A, B and C in 3 cases. No article reported any significant difference between surgical and conservative treatments in terms of DASH or PRWE, whereas strength was sometimes improved when surgical treatment was used. Radiological results were always better after surgical treatment. The rate of complications varied greatly, greater, equally or lower compared to conservative treatment depending on the series. All in all, there is no consensus to assert that a conservative treatment is more justified than a surgical treatment to treat distal radius fractures after the age of 65. Most authors consider that the long-term clinical outcome is identical and that the radiological result is better after surgical treatment. The fact that the fixation of a distal radius fracture by a volar locking plate after 65 years speeds up the recovery remains to be proven.

Intra-articular distal radius fractures in elderly patients: a randomized prospective study of casting versus volar plating

We compared outcomes in elderly patients with intra-articular distal radius fractures treated by closed reduction and plaster immobilization or open reduction and internal fixation with a volar plate. Ninety-seven patients older than 60 years were randomly allocated to conservative (47 patients) or surgical (50 patients) treatment. Over a 2-year period, we assessed patient-rated wrist evaluation score, DASH (disability arm, shoulder and hand) questionnaire, pain, wrist range of motion, grip strength, and radiological parameters. The functional outcomes and quality of life were significantly better after volar plating fixation compared with conservative treatment. We found that restoration of the articular surface, radial inclination, and ulnar variance affected the outcomes, but the articular step-off did not. Twenty-five per cent of the patients with conservative treatment had secondary loss of reduction. We conclude that surgical plating leads to better outcomes than conservative treatment for elderly patients with intra-articular distal radius fractures.

Fracturas del radio distal: encuesta sobre preferencias de manejo y tratamiento

Objetivo: La fractura de la extremidad distal del radio (FEDR) es un traumatismo frecuente a cualquier edad y su tratamiento es aún tema de controversia. El objetivo del trabajo es determinar la tendencia actual de manejo en cirujanos especialistas en cirugía de la mano.

Material y método: Se realiza una encuesta electrónica remitida por correo electrónico a miembros de la Sociedad Española de Cirugía de la Mano (SECMA). A los participantes se les pregunta por sus preferencias respecto a clasificación, tratamiento conservador y quirúrgico de estas fracturas. Se valoran sus resultados con la evidencia científica actual al respecto.

Resultados: Se obtuvieron 49 respuestas (14,41% de los socios encuestados) La mayoría tenían más de 21 años de experiencia como cirujanos de mano. La clasificación más usada fue la de AO-ASIF. Las FEDR estables se realiza de forma conservadora con yeso sin incluir el codo. El tratamiento de elección quirúrgico es la fijación interna con placas volares y tornillos. No es habitual la utilización de la artroscopia como asistente de la reducción y en casos de inestabilidad de la RCD se trata mediante fijación con agujas transfixiantes o tornillos de fijación de la estiloides cubital. No hay consenso de utilización de suplementos biológicos ni tratamiento coadyuvantes de la osteporosis. La toma de decisiones se realiza tomando en cuenta su experiencia personal y los conocimientos adquiridos durante su vida profesional.

Conclusiones: El manejo de las FEDR varía en función de la experiencia de cada cirujano y no se correlaciona necesariamente con la evidencia científica publicada al respecto. Su manejo es heterogéneo y se necesitan estudios mayores y elaborar patrones de consenso para el manejo de estas lesiones.

A combined randomised and observational study of surgery for fractures in the distal radius in the elderly (CROSSFIRE)-a study protocol

Fractures of the distal radius are common and occur in all age groups. The incidence is high in older populations due to osteoporosis and increased falls risk. Considerable practice variation exists in the management of distal radius fractures in older patients ranging from closed reduction with cast immobilisation to open reduction with plate fixation. Plating is currently the most common surgical treatment. While there is evidence showing no significant advantage for some forms of surgical fixation over conservative treatment, and no difference between different surgical techniques, there is a lack of evidence comparing two of the most common treatments used: closed reduction and casting versus plating. Surgical management involves significant costs and risks compared with conservative management. High-level evidence is required to address practice variation, justify costs and to provide the best clinical outcomes for patients.

METHODS AND ANALYSIS

This pragmatic, multicentre randomised comparative effectiveness trial aims to determine whether plating leads to better pain and function and is more cost-effective than closed reduction and casting of displaced distal radius fractures in adults aged 60 years and older. The trial will compare the two techniques but will also follow consenting patients who are unwilling to be randomised in a separate, observational cohort. Inclusion of non-randomised patients addresses selection bias, provides practice and outcome insights about standard care, and improves the generalisability of the results from the randomised trial.

ETHICS AND DISSEMINATION

CROSSFIRE(Combined Randomised and Observational Study of Surgery for Fractures In the distal Radius in the Elderly) was reviewed and approved by The Hunter New England HREC (HNEHREC Reference No: 16/02/17/3.04). The results of the trial will be published in a peer-reviewed journal and will be disseminated via various forms of media. Results will be incorporated in clinical recommendations and practice guidelines produced by professional bodies.

REGISTRATION

CROSSFIRE has been registered with the Australian and New Zealand Clinical Trials Registry (ANZCTR: ACTRN12616000969460).

Developing an instrument for the measurement of grip ability after distal radius fracture

BACKGROUND

Distal radius fracture (DRF) often causes reduced ability to perform activities of daily living (ADLs). There is a need for recurrent evaluation of the ability to perform ADL in the early stage of rehabilitation as a complement to traditional functional measures.

AIM

Develop a short and simple performance test for use in clinical practice through modification of the Sollerman Grip Function Test (GFT).

METHOD

DRF patients and controls performed the GFT. The tasks that discriminated patients from controls were calculated for sensitivity to change and correlated to the QuickDASH questionnaire at three subsequent occasions. Interrater reliability was tested.

RESULTS

Twelve GFT tasks discriminated DRF patients from healthy controls. One task was excluded due to heavy load. Remaining 11 tasks were all sensitive to change. Four tasks with correlation to the QuickDASH and representing the grip types most frequently used in ADL came to constitute the Wrist Performance Test (WPT). A test-retest showed satisfactory interrater reliability (rs = 0.87).

CONCLUSION

A short performance test was developed through modification of the GFT. It is easy to use in clinical practice to evaluate the rehabilitation process after DRF.

Do radiological and functional outcomes correlate for fractures of the distal radius?

AIMS

We conducted a study to determine whether radiological parameters correlate with patient reported functional outcome, health-related quality of life and physical measures of function in patients with a fracture of the distal radius.

PATIENTS AND METHODS

The post-operative palmar tilt and ulnar variance at six weeks and 12 months were correlated with the Patient Rated Wrist Evaluation, Disabilities of the Arm, Shoulder and Hand, and EuroQol scores, grip strength, pinch strength and range of movement at three, six and 12 months for 50 patients (mean age 57 years; 26 to 85) having surgical fixation, with either percutaneous pinning or reconstruction with a volar plate, for a fracture of the distal radius.

RESULTS

Radiological parameters were found to correlate poorly with the patient reported outcomes (r = 0.00 to 0.47) and physical measures of function (r = 0.01 to 0.51) at all intervals.

CONCLUSION

This study raises concerns about the use of radiological parameters to determine management, and to act as a surrogates for successful treatment, in patients with a fracture of the distal radius. Restoration of 'normal' radiographic parameters may not be necessary to achieve a satisfactory functional outcome for the patient. Cite this article: Bone Joint J 2017;99-B:376-82.

Supervised physical therapy vs home exercise program for patients with distal radius fracture: A single-blind randomized clinical study

STUDY DESIGN

Randomized clinical study.

INTRODUCTION

Supervised physical therapy (PT) and home exercise programs (HEPs) are frequently used in the rehabilitation of patients with distal radius fracture (DRF). However, there is no consensus as to whether unsupervised HEP provides comparable benefits to those achieved by supervised PT.

PURPOSE OF THE STUDY

To compare the improvements in pain and functional status between a supervised PT program and unsupervised HEP in DRF patients older than 60 years.

METHODS

A total of 74 patients were randomized into 2 groups. One group received 12 sessions of supervised PT (n = 37), and the other group followed an exercise program at home (n = 37). Three evaluations were performed, before the initiation of treatment, at 6-week, and 6-month follow-up. The study conducted a statistical power analysis to detect an intergroup difference score of 15 points on the Patient-Rated Wrist Evaluation (PRWE). The t-test or Mann-Whitney test was used, and it was set with a significance level of .05.

RESULTS

The supervised PT group showed clinically significant differences in the total PRWE score at 6 weeks (17.67 points, P = .000) in the PRWE function score (15.2 points, P = .000) and in the PRWE pain score (5.6 points, P = .039). There was also a significant difference in the total PRWE score at 6-month follow-up (17.05 points, P = .000) in the PRWE function score (14.5 points, P = .000) and in the PRWE pain score (2.5 points, P = .35).

CONCLUSIONS

A supervised PT program is more effective for improving function in the short- and medium-term when compared with HEP in patients older than 60 years with DRF extraarticular without immediate complications.
