External Fixation Versus Volar Locking Plate for Unstable Dorsally Displaced Distal Radius Fractures-A 3-Year Follow-Up of a Randomized Controlled Study

Surgical vs. Conservative Treatment of Distal Radius Fractures in the Elderly: A Systematic Review and Meta-Analysis

Elderly patients with distal radius fractures (DRFs) pose a significant medical challenge due to their high incidence and related healthcare costs. Both surgical methods like volar plate fixation and conservative approaches such as casting are common, yet their relative effectiveness remains unclear. This review and meta-analysis compare surgical and conservative treatments, focusing on wrist functionality, upper extremity performance, grip strength, and pain after one year. A literature search was conducted in PubMed, Cochrane Library, Scopus, and Web of Science up to November 6, 2024, to find randomized controlled trials (RCTs) for DRFs in patients aged 65 and older. Thirteen RCTs with 2400 participants were included. After one year, there was no significant difference in wrist function between groups (mean difference (MD)=-1.24; 95% confidence interval (CI) -2.61 to 0.13; p=0.78; I²=78%), but upper limb function favored surgery as measured by the Disabilities of the Arm, Shoulder, and Hand (DASH) score (MD=-2.32; 95% CI -3.66 to -0.98; p=0.0007; I²=83%). Surgical treatment significantly improved grip strength (MD=3.82; 95% CI 1.55 to 6.09; p=0.001) but resulted in higher pain levels (MD=2.73; 95% CI 1.16 to 4.31; p=0.0007). Results showed substantial heterogeneity and publication bias. Surgical treatment offers slight functional advantages in grip strength and DASH scores but is associated with higher pain; conservative treatment remains viable with minimal differences in long-term wrist function. Further high-quality studies are necessary to address heterogeneity and publication bias.

Long-term outcome for patients with distal radius fractures treated with volar locking plates versus percutaneous wires

BACKGROUND

Fractures of the distal radius are the most common fractures of the upper extremity. The choice of surgical method has been debated and studies show that short-term differences, in favour of volar locking plates, are indistinguishable at 1 year follow-up. Few studies have investigated long-term outcomes beyond one year. The aim of this study was to investigate long-term (6-10 years) patient-reported outcomes after distal radius fracture surgery, and to determine how fracture pattern/complexity (Buttazzoni fracture type) affects the results.

METHODS

303 patients surgically treated for a distal radius fracture, from 2012-2016 were included. The questionnaires used were PRWE, Quick-DASH and EQ-5D. Previous studies have shown that fracture type influences the choice of surgical method and therefore fracture type was adjusted for in the statistical analysis.

RESULTS

We found that patients treated with K-wires had significantly better Quick-DASH scores (p <0.05) and a lower degree of pain (PRWE pain scale) (p <0.05) than patients treated with volar locking plates. There was no difference between the two groups regarding the remaining outcome measures for any Buttazzoni type of fracture.

CONCLUSION

On the basis of these results, K-wires can be considered an equivalent option to locking plates because of equal or better long-term outcomes, lower costs, and shorter operation times.

Reporting of patient-reported outcomes amongst randomized clinical trials in plastic surgery: a systematic review using CONSORT-PRO

BACKGROUND

Patient-reported outcomes (PROs) are key to investigating patient perspectives in randomized controlled trials (RCTs). Standardization of PRO reporting is critical for trial generalizability and the application of findings to clinical practice. This systematic review aimed to evaluate the reporting quality of RCTs published in the top plastic surgery journals according to the consolidated standards of reporting trials (CONSORT)-PRO extension.

METHODS

We completed a comprehensive search of MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. All RCTs with a validated PRO endpoint published in the top 10 plastic surgery journals (based on the 2021 Web of Science Impact Factor) from 2014 to 2023 were included. Two reviewers independently extracted data and scored the included studies using the CONSORT-PRO checklist. Univariate regression was applied to assess factors associated with reporting adherence. Studies were assessed for their risk of bias using the Cochrane Risk of Bias 2.0 tool.

RESULTS

A total of 88 RCTs were included. PROs were the primary endpoint in 50 (57%) and the secondary endpoint of 38 (43%) studies. Mean overall reporting adherence was poor (39% (±12) and 36% (±13) in studies with PRO as primary and secondary endpoints, respectively). The presence of industry support was significantly associated with greater adherence.

CONCLUSIONS

There is low adherence to the CONSORT-PRO extension among plastic surgery RCTs published in the top 10 plastic surgery journals. We encourage journals and authors to endorse and apply the CONSORT-PRO extension. This may optimize the dissemination of clinical findings from RCTs and assist patient-centered care.

Complications Following Volar Locking Plate Fixation of Distal Radius Fractures in Adults: A Systematic Review of Randomized Control Trials

PURPOSE

The purpose of this study was to assess the incidence of postoperative complications following volar locking plate (VLP) fixation of distal radius fractures (DRFs).

METHODS

A search using keywords and subject headings to represent the concepts of volar plating and radius fractures was generated. Databases such as MEDLINE (Ovid), Embase (Elsevier), Scopus (Elsevier), and SPORTDiscus (EBSCO) were searched from inception to November 24, 2021, for randomized controlled trials that reported complications following DRF treated with VLP. Inclusion criteria were studies with adult patients (aged ≥18 years) randomized to VLP fixation without other concomitant surgical interventions, with a minimum follow-up of 3 months. Study sample characteristics and post-surgical complications were extracted. The Cochrane Risk of Bias tool was used to evaluate quality of evidence.

RESULTS

Of the 4,059 articles identified using the search strategy, 1,778 titles/abstracts and 856 full-text articles were screened for inclusion, of which 35 articles were included for data extraction. Overall, 1,419 patients with a DRF were randomized to VLP fixation. The mean age was 60.3 years. The overall complication rate was 30.8% following VLP fixation, with 12.4% being major complications. The most common complications were median nerve-related (7.1%) and hardware removal (6.8%), secondary to other complications. Tenosynovitis was the most common tendon-related complication (3.4%). Other complications included complex regional pain syndrome (2.4%), malunion (1.3%), superficial wound infections (1.9%), and tendon rupture (1.3%).

CONCLUSIONS

A meta-analysis of high-quality studies that discuss the complications after VLP fixation for DRF showed an overall complication rate of 30.8%. VLP may be related to more hardware-related complications than those previously reported.

Trends in the Utilization of Computed Tomography in Operative Treatment of Distal Radius Fractures

Purpose

To identify patient, surgeon, and injury characteristics associated with preoperative computed tomography (CT) scan utilization for operative distal radius fractures (DRF). In addition, we aimed to determine if preoperative CT was associated with treatment methods other than isolated volar-locked plating (VLP).

Methods

We retrospectively reviewed all operatively treated adult DRFs within our health care system from 2016 to 2020. Baseline demographics, injury, treatment characteristics, and the fellowship training of the 44 included surgeons were recorded. We compared cases with and without a preoperative CT, and an adjusted logistic regression model was generated to determine the odds of having a preoperative CT.

Results

A total of 1,204 operatively treated DRFs performed by 44 surgeons were included. CT utilization increased during the study period. Intra-articular fractures accounted for 76% of cases, and preoperative CT scans were ordered in 243 of 1240 cases (20%). Overall, isolated VLP was used in 83% of cases. Cases with a preoperative CT were more likely to be treated with an alternative method of fixation (such as dorsal plating). The adjusted logistic regression model demonstrated that male sex (OR 1.62; 95% CI: 1.16, 2.26), intra-articular fractures (OR 3.11; 95% CI: 1.87, 5.81), and associated fractures (OR 2.69; 95% CI: 1.82, 3.98) had a significantly increased odds of having a preoperative CT. Fellowship training was not associated with increased CT utilization overall, but hand surgeons were more likely to use a CT in Orthopaedic Trauma Association-C3 fractures.

Conclusions

Patient and injury characteristics are associated with CT utilization in operative DRFs. Preoperative CTs are associated with alternative fixation approaches, as cases with a CT were more likely to use fixation methods other than isolated VLP. The costs and benefits of CT scans must be carefully weighed against whether this modality adds value or improves outcomes in treating DRFs.

Treatment and outcome of AO/OTA type C distal radius fractures: 12 199 fractures from the Swedish Fracture Register

The aim of this study was to examine the epidemiology, treatment, and patient-reported outcome of AO/OTA type C distal radius fractures (DRF) using data from a large national fracture register. We used prospectively collected data from the Swedish Fracture Register covering all AO/OTA type C DRFs registered between April 2012 and December 2018. Data on fracture type, epidemiology, trauma-mechanism, and treatment had been recorded by the treating physician. Patients had been sent an outcome questionnaire including EQ-VAS, EQ-5D, and the SMFA at the time of injury and 12 months after. A total of 12 199 cases with AO/OTA type C fracture were identified. AO/OTA type C1 fracture was most common, with 5400 cases, followed by AO type C2 with 4304 and AO/OTA type C3 with 2495. Cast treatment and surgical treatment with volar locking plate fixation were the most common treatments. Patient-reported outcome measures worsened significantly one year after the fracture, and 56% reported moderate problems with pain and discomfort one year after the fracture. Patients treated with a volar plate reported a significantly larger deterioration in EQ-5D outcome compared to patients treated with a cast. No treatment method was found to be superior. A good outcome after a type C fracture is possible, but many patients do not recover completely. Our findings indicate a relatively better self-reported outcome for patients treated with a cast, but as treatment was not randomized the clinical relevance is unclear.

Effectiveness and Safety of Different Treatment Modalities for Patients Older Than 60 Years with Distal Radius Fracture: A Network Meta-Analysis of Clinical Trials

The aim of this study was to compare the clinical effectiveness and complications of different treatment modalities for elderly patients with distal radius fracture (DRF).

METHODS

We performed a network meta-analysis (NMA) of randomized clinical trials (RCTs). Eight databases were searched. The eligibility criteria for selecting studies were RCTs that compared different treatment modalities (surgical or nonoperative) in patients older than 60 years with displaced or unstable intra-articular and/or extra-articular DRFs.

RESULTS

Twenty-three RCTs met the eligibility criteria (2020 patients). For indirect comparisons, the main findings of the NMA were in volar locking plate (VLP) versus cast immobilization, with the mean differences for the patient-rated wrist evaluation (PRWE) questionnaire at -4.45 points (p < 0.05) and grip strength at 6.11% (p < 0.05). Additionally, VLP showed a lower risk ratio (RR) of minor complications than dorsal plate fixation (RR: 0.02) and bridging external fixation (RR: 0.25). Conversely, VLP and dorsal plate fixation showed higher rates of major complications.

CONCLUSIONS

Compared with other treatment modalities, VLP showed statistically significant differences for some functional outcomes; however, most differences were not clinically relevant. For complications, although most differences were not statistically significant, VLP was the treatment modality that reported the lowest rate of minor and overall complications but also showed one of the highest rates of major complications in these patients.

Outcomes of the Management of Distal Radius Fractures in the Last 5 Years: A Meta-analysis of Randomized Controlled Trials

Objective  Over the last decades, volar locking plates (VLPs) have been the mainstay treatment for distal radius fractures (DRFs). With the growing body of evidence, we systematically reviewed studies on recent VLP modifications. Methods  A systematic search was performed in the PubMed/MEDLINE database for studies published in English in the past five years. The inclusion criteria were randomized controlled trials (RCTs) on the operative treatment of DRFs. We excluded ongoing trials and studies not directly addressing DRF. The primary outcomes assessed were subjective (such as the scores on the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire, the Patient-rated Wrist Evaluation [PRWE], the European Quality of Life-5 Dimensions [EQ-5D], the 36-item Short Form Health Survey [SF-36], and the Visual Analog Scale [VAS]) and objective clinical outcomes (the complication rate). Results  We identified 29 articles published from 2016 to 2020 with high quality of evidence, except for one, which had evidence of moderate quality. In total, 3,079 DRFs were analyzed in the present study. All studies except one had a greater proportion of female participants, and only in 1 study the mean age of the sample was < 40 years old. There were no significant differences between the VLP and external fixation (EF) in terms of the scores on the DASH ( p  = 0.18) and PRWE ( p  = 0.77). The VLP alone without pronator quadratus (PQ) repair yielded significantly better outcomes. Conclusion  In unstable fractures, the VLP and EF yielded comparable long-term results. There is no clear benefit of adding PQ repair to current the VLP surgical technique. Level of Evidence  Level I.

A Cost-Effectiveness Analysis of the Various Treatment Options for Distal Radius Fractures

Purpose

To conduct a cost-effectiveness study of nonsurgical and surgical treatment options for distal radius fractures using distinct posttreatment outcome patterns.

Methods

We created a decision tree to model the following treatment modalities for distal radius fractures: nonsurgical management, external fixation, percutaneous pinning, and plate fixation. Each node of the model was associated with specific costs in dollars, a utility adjustment (quality-adjusted life year [QALY]), and a percent likelihood. The nodes of the decision tree included uneventful healing, eventful healing and no further intervention, carpal tunnel syndrome, trigger finger, and tendon rupture as well as associated treatments for each event. The percent probabilities of each transition state, QALY values, and costs of intervention were gleaned from a systematic review. Rollback and incremental cost-effectiveness ratio analyses were conducted to identify optimal treatment strategies. Threshold values of $50,000/QALY and $100,000/QALY were used to distinguish the modalities in the incremental cost-effectiveness ratio analysis.

Results

Both the rollback analysis and the incremental cost-effectiveness ratio analysis revealed nonsurgical management as the predominant strategy when compared with the other operative modalities. Nonsurgical management dominated external fixation and plate fixation, although it was comparable with percutaneous fixation, yielding a $2,242 lesser cost and 0.017 lesser effectiveness.

Conclusions

The cost effectiveness of nonsurgical management is driven by its decreased cost to the health care system. Plate and external fixation have been shown to be both more expensive and less effective than other proposed treatments. Percutaneous pinning has demonstrated more favorable effectiveness in the literature than plate and external fixation and, thus, may be more cost effective in certain circumstances. Future studies may find value in investigating further clinical aspects of distal radius fractures and their association with nonsurgical management versus that with plate fixation.

Extensor Tendon Injury After Volar Locking Plating for Distal Radius Fractures: A Systematic Review

Distal radius fractures are common orthopedic injuries. Treatment has varied historically, but volar locking plating currently predominates. Although flexor tendon injury is a well-studied complication of this operation, extensor tendon injury is less well studied. The purpose of this review is to search the literature and present the epidemiology, presentation, and treatment of this complication. The Cochrane, EMBASE, PubMed, and SCOPUS databases were searched for the terms "volar" + "radius" + ("plate" OR "plating") + "extensor." Ninety final studies were included for analysis in this review. The incidence of extensor tendon rupture varies from 0% to 12.5%; the extensor pollicis longus is most commonly ruptured. The presentation and management of extensor tendon injury after injury, intraoperatively, and postoperatively are summarized. Radiographic views are described to detect screw prominence and minimize intraoperative risk. Extensor tendon injury after volar locking plate for distal radius fractures is an uncommon injury with several risk factors including dorsal screw prominence and fracture fragments. Removal of hardware and tendon transfers or reconstruction may be necessary to prevent loss of extensor mechanism.

Radiographic Outcomes following K-Wire Augmentation of Dorsal Spanning Plate Fixation for Intra-Articular Fractures of the Distal Radius

Background  Restoration of articular surface alignment is critical in treating intra-articular distal radius fractures. Dorsal spanning plate fixation functions as an internal distraction mechanism and can be advantageous in the setting of highly comminuted fracture patterns, polytrauma patients, and patients with radiocarpal instability. The addition of K-wires to support articular surface reduction potentially augments fracture repair stability. Questions/Purposes  We examined the radiographic outcomes and maintenance of reduction in patients with comminuted intra-articular distal radius fractures treated with K-wire fixation of articular fragments followed by dorsal spanning plate application. Patients and Methods  We reviewed 35 consecutive patients with complex intra-articular distal radius fractures treated with dorsal spanning plate and K-wire fixation between April 2016 and October 2019. AO classification was recorded: B1 (3), B3 (2), C2 (2), C3 (28). A two-tailed paired t -test was used to compare findings immediately post-dorsal spanning plate surgery and at final follow-up after dorsal spanning plate removal. Results  Mean patient age was 43.3 years (19-78 years). Mean follow-up was 7.8 months (SD 4.3 months) from surgery and 2.5 months from pin removal (SD 2.6 months). All patients achieved radiographic union. Radial height (mean interval change (MIC) 0.2 mm, SD 2.2, p  = 0.63), articular step-off (MIC 0.1 mm, SD 0.6 mm, p  = 0.88), and radial inclination (MIC -1.1 degrees, SD 3.7 degrees, p  = 0.10) did not change from post-surgery to final follow-up. Ulnar variance (MIC -0.9 mm, SD 2.0 mm, p  = 0.02) and volar tilt (MIC -1.5 degrees, SD 4.4 degrees, p  = 0.05) were found to have decreased. Conclusion  Dorsal spanning plate augmented with K-wire fixation for comminuted intra-articular distal radius fractures in polytrauma patients allows for immediate weightbearing and maintains articular surface alignment at radiographic union and may provide better articular restoration than treatment with dorsal spanning plate alone. Level of Evidence  This is a Level IV , therapeutic study.

Prolonged Operative Time Associated with Increased Healthcare Utilization after Open Reduction and Internal Fixation of Intra-Articular and Extra-Articular Distal Radial Fractures: An Analysis of 17,482 Cases

Background  The current literature does not contain a quantitative description of the associations between operative time and adverse outcomes after open reduction and internal fixation (ORIF) of distal radial fractures (DRF). Questions/Purpose  We aimed to quantify associations between DRF ORIF operative time and 1) 30-day postoperative health care utilization and 2) the incidence of local wound complications. Methods  The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for DRF ORIF cases (January 2012-December 2018). A total of 17,482 cases were identified. Primary outcomes included health care utilization (length of stay [LOS], discharge dispositions, 30-day readmissions, and reoperations) per operative-time category. Secondary outcome was incidence of wound complications per operative-time category. Multivariate regression was conducted to determine operative-time categories associated with increased risk while adjusting for demographics, comorbidities, and fracture type. Spline regression models were constructed to visualize associations. Results  The 121 to 140-minute category was associated with significantly higher risk of a LOS > 2 days (odds ration [OR]: 1.64; 95% confidence interval [CI]:1.1-2.45; p  = 0.014) and nonhome discharge (OR: 1.72; 95% CI:1.09-2.72; p  = 0.02) versus 41 to 60-minute category. The ≥ 180-minute category exhibited highest odds of LOS > 2 days (OR: 2.08; 95%CI: 1.33-3.26; p  = 0.001), nonhome discharge disposition (OR: 1.87; 95% CI: 1.05-3.33; p  = 0.035), and 30-day reoperation occurrence (OR: 3.52; 95% CI: 1.59-7.79; p  = 0.002). There was no association between operative time and 30-day readmission ( p  > 0.05 each). Higher odds of any-wound complication was first detected at 81 to 100-minute category (OR: 3.02; 95% CI: 1.08-8.4; p  = 0.035) and peaked ≥ 181 minutes (OR: 9.62; 95% CI: 2.57-36.0; p  = 0.001). Spline regression demonstrated no increase in risk of adverse outcomes if operative times were 50 minutes or less. Conclusion  Our findings demonstrate that prolonged operative time is correlated with increased odds of health care utilization and wound complications after DRF ORIF. Operative times greater than 60 minutes seem to carry higher odds of postoperative complications.

Distal radius fractures in the superelderly: an observational study of 8486 cases from the Swedish fracture register

Background

The distal radius fracture (DRF) is the most common fracture in adults. With an ageing population, the number of wrist fractures in the superelderly (≥ 80 years) is expected to rise. Optimal treatment for displaced DRFs remains controversial, especially in the superelderly group. In addition, basic knowledge of the outcome after a DRF in this heterogenic group is lacking. The aim of this study was to study injury characteristics, treatment and outcome of DRFs in superelderly patients using data from a large national register.

Methods

We used prospectively collected data from the Swedish Fracture Register. All distal radius fractures registered between April 2012 and December 2018 in patients ≥ 80 years of age were included. Data on epidemiology, fracture type, trauma mechanism and treatment are registered by the physician treating the patient. Patients are also sent a subjective outcome questionnaire including EQ-5D, EQ-VAS and Short Musculoskeletal Function Assessment questionnaire (SMFA-score) at the time of injury and after 12 months. The 12-month questionnaire was sent to those who had completed the questionnaire at the time of injury. A Mann–Whitney U-test was used to assess differences between treatment methods.

Results

Mean age for this population was 86 years (80–105 years), a majority of the patients were female (86.7%). The dominating injury mechanism was a simple fall (74.6%) in the patient’s residence. The majority of fractures were AO type A (70%) followed by AO type C (20.9%) and type B (8.6%). The incidence of open fractures was significantly higher in females (2.6%) compared to males (1.5%). A majority of the fractures were treated with a cast (87.5%) with volar locking plate as the second most common treatment method (6.6%). Patient-reported outcome measures (PROMs) EQ-5D, EQ-VAS and the Arm Hand Function Index of the SMFA-score deteriorated somewhat one year after injury compared to pre-injury. PROMs did not correlate to treatment with cast or a volar plate.

Conclusions

This nationwide register study provides detailed data on DRFs in the superelderly regarding epidemiology, treatment and self-reported outcome. A good self-reported outcome is possible, but many patients do not recover completely. PROMs did not correlate to type of treatment. The frequency of open fractures was significantly higher in females. The reason for this is unclear but different skin thickness in older males versus females may be one explanation.

Radiological, Clinical and Functional Outcomes of Combined Dorsal and Volar Locking Plate Osteosynthesis for Complex Distal Radius Fractures

PURPOSE

The purpose of this study was to assess the short- to mid-term radiologic, clinical, and functional outcomes of patients treated with combined dorsal and volar locking plating for internal fixation of complex, comminuted, intra-articular, distal radius fractures.

METHODS

We performed a retrospective review of 34 patients treated with combined dorsal and volar locking plates for the internal fixation of complex, comminuted, intra-articular distal radius fractures. Radiographic and clinical parameters were recorded at a mean of 48 months after surgery. Activities of daily living and quality of life were assessed by the Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation questionnaires.

RESULTS

Compared with the contralateral wrist, the treated wrist regained 73% of flexion, 81% of extension, 86% of ulnar deviation, 90% of radial deviation, 98% of pronation, 99% of supination, and 93% of grip strength. Mean Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation scores were 11 (range, 0-78) and 11 (range, 0-77), respectively. Radial height and radial inclination were restored anatomically in 24% and 41% of patients, respectively, while volar tilt and ulnar variance were restored in 68% of patients.

CONCLUSION

The overall functional and radiologic outcome of patients with comminuted intra-articular complex distal radius fractures treated with the combined dorsovolar plate osteosynthesis was good to excellent.

Forecasting effects of "fast-tracks" for surgery in the Swedish national guidelines for distal radius fractures

BACKGROUND AND PURPOSE

National guidelines for treatment of distal radius fractures (DRFs) were presented in Sweden in 2021. In the guidelines, a fast-track is recommended for 4 subgroups of highly unstable DRFs. Regardless of the results of the closed reduction these are recommended for surgery within 1 week of injury. This study aims to evaluate the potential consequences of the newly presented national guidelines on incidence of surgical interventions.

PATIENTS AND METHODS

In all, 1,609 patients (1,635 DRFs) with primary radiographs after a DRF between 2014 and 2017 at two Swedish hospitals were included in a retrospective cohort study. An estimation was made of the percentage of patients in the historical pre-guidelines cohort, that would have been recommended early primary surgery according to the new national guidelines compared to treatment implemented without the support of these guidelines.

RESULTS

On a strict radiological basis, 32% (516 out of 1635) of DRFs were classified into one of the 4 defined subgroups. At 9-13 days follow-up, cast treatment was converted into delayed primary surgery in 201 cases. Out of these, 56% (112 out of 201) fulfilled the fast-track criteria and would with the new guidelines have been subject to early primary surgery.

INTERPRETATION

The fast-track regimen in the new guidelines, has a high likelihood of identifying the unstable fractures benefitting from early primary surgery. If the proposed Swedish national guidelines for DRF treatment are implemented, a greater proportion of fractures would be treated with early primary surgery, and a delayed surgery avoided in the majority of cases. The potential benefits in relation to possible costs when using the fast-track criteria in every day practice are still unknown.

Distal Radial Fracture Fixation in Adults using Intramedullary Elastic Wires Augmented with either Cast Immobilisation or External Fixation

Introduction:

The aim of this study was to evaluate the clinical outcomes following treatment of distal radial fractures using intramedullary elastic wires with a combination of either cast immobilisation or external fixation.

Materials and methods:

A total of 42 patients (24 females and 18 males) aged 40 to 78 years who presented with displaced and unstable, closed or grade I open, extra- and/or intra-articular fractures of the distal radius were included in the study. Twenty-seven fractures were AO/OTA Type A2-A3 and 15 Type C1-C2. Twenty-four patients were treated with antegrade intramedullary (IM) fixation with elastic wires followed by cast immobilisation and 18 required an external fixator in lieu of casting.

Results:

Final follow-up evaluation was conducted 12 months post-surgery using Sarmiento's modification of Lindstrom criteria and the demerit point system of Gartland and Werley. Successful fracture union was observed in all patients between eight to 14 weeks. Using Sarmiento's modification of Lindstrom criteria, 12 patients (28.6%) had excellent, 23 (54.8%) had good and 7 (16.6 %) had fair results. Based on the functional evaluation using the demerit point system of Gartland and Werley, 13 patients (31%) had excellent, 25 (59.5%) had good and four (9.5%) had fair results. None of the patients had a poor outcome using either of these criteria. Although a fracture union rate of 100% was confirmed clinically and radiographically, eight out of the 42 patients had minor complications in our study. One patient had uneventful IM migration of the wires, one patient reported a feeling of wire loosening, three patients complained of joint stiffness and soft tissue irritation, and three others reported on-going pain. The total cost of all implants used per case was less than INR 1,000.

Conclusions:

Good to excellent functional and radiographic outcomes with easy to manage complications are achieved with the techniques described. Patient selection is key to determining which particular method should be prescribed in a given case.

In adults, early mobilization may be beneficial for distal radius fractures treated with open reduction and internal fixation: a systematic review and meta-analysis

Objectives

It remains debatable if early mobilization (EM) yields a better clinical outcome than the late mobilization (LM) in adults with an acute and displaced distal radial fracture (DRF) of open reduction internal fixation (ORIF). Therefore, we aimed to perform a systematic review and meta-analysis of randomized controlled trials (RCTs), comparing clinical results with the safety of EM with LM following ORIF.

Methods

Databases such as Medline, Cochrane Central Register, and Embase were searched from Jan 1, 2000, to July 31, 2021, and RCTs comparing EM with LM for DRF with ORIF were included in the analysis. The primary outcome of study included disabilities of the Arm, Shoulder, and Hand (DASH) score at different follow-up times. Wherever the secondary outcomes included patient-rated wrist evaluation (PRWE), grip strength (GS), visual analog scale (VAS), wrist range of motion (WROM), and associated complications, the two independent reviewers did data extraction for the analysis. Effect sizes of outcome for each group were pooled using random-effects models; thereafter, the results were represented in the forest plots.

Results

Nine RCTs with 293 EM and 303 LM participants were identified and included in the study. Our analysis showed that the DASH score of the EM group was significantly better than LM group at the six weeks postoperatively (− 10.15; 95% CI − 15.74 to − 4.57, P < 0.01). Besides, the EM group also had better outcomes in PRWE, GS and WROM at 6 weeks. However, EM showed potential higher rate for implant loosening and/or fracture re-displacement complication (3.00; 95% CI 1.02–8.83, P = 0.05).

Conclusion

Functionally, at earlier stages, EM for patients with DRF of ORIF may have a beneficial effect than LM. The mean differences in the DASH score at 6 weeks surpassed the minimal clinically important difference; however, the potentially higher risk of implant loosening and/or fracture re-displacement cannot be ignored. Due to the lack of definitive evidence, multicenter and large sample RCTs are required for determining the optimal rehabilitation protocol for DRF with ORIF.

Interventions for Distal Radius Fractures: A Meta-analysis of Comparison Studies

Background  Distal radius fractures are one of the most frequent orthopaedic injuries. There are many effective treatment methods, such as volar plate, dorsal plate, percutaneous pins, external fixation, and casting; however, comparison of the treatment outcomes has not been thoroughly investigated. Our purpose is to determine if volar plating is the superior treatment method for distal radius fractures. We will address this through the following questions: First, is volar plating superior to dorsal plating, percutaneous pins, external fixation, or casting in terms of reported complications? Second, does volar plating produce superior functional outcomes to dorsal plating, percutaneous pins, external fixation, or casting? Third, are the radiographic outcomes superior for volar plating when compared with dorsal plating, percutaneous pins, external fixation, or casting? Methods  MEDLINE, Academic Search Ultimate, Academic Search Complete, CINAHL Plus, and JSTOR databases, as well as manual search, were used to identify papers comparing complications and functional results of volar plating to other treatment methods for distal radius fractures published after the year 2000. Complication data and function scores were recorded. Risk of bias was assessed using the Cochrane Risk of Bias Tool and data was analyzed for meta-analysis using Cochrane ReviewManager software. Results  Compared with dorsal plate, volar plate performed significantly better in Gartland and Werley score. Volar plating outperformed percutaneous pins for loss of reduction, infection, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and ulnar deviation. Loss of reduction, malunion, Patient Related Wrist Evaluation (PRWE) score, DASH score, grip strength, ulnar deviation, and supination were significantly better for volar plating when compared with casting. When compared with external fixation, volar plating had significantly less cases of infection, lower QuickDASH score, and higher range of motion for flexion, pronation, and supination. All other complication and functional outcomes were not significantly different. Conclusions  Distal radius fractures treated with volar plating showed relatively better measures of complications, function scores, and range of motion than other treatment methods; however, there was no significant difference in healing time when compared with percutaneous pins. More studies are needed to compare the rest of the treatment methods with each other.

Hot Topics in Hand and Wrist Surgery

The field of hand surgery continues to evolve in new and exciting directions. Advances in diagnosis and management for common complaints and complex injuries allow higher-level care, while still being cognizant of the cost of health care delivery. Indications and protocols for past paradigm shifts, such as volar locked plating for distal radial fractures, continue to be honed, and the outcomes seen for modern flexor tendon repairs are impressive. Open questions remain, but promising results for scaphoid nonunion surgery and peripheral nerve reconstruction with processed allograft will continue to shed light on these unsolved problems.

Volar locking plate versus external fixation in distal radius fractures: A meta-analysis

The purpose of this meta-analysis is to evaluate the efficacy of plate or external fixator treatments in distal radius fractures, based not only on clinical and radiographic parameters but on Health Related Quality of Life (HRQOL) parameters. The Preferred Reporting Items for Systematic Reviews and Metanalyses (PRISMA) guidelines were followed when conducting this systematic review. The Revised Assessment of Multiple Systematic Reviews (RAMSTAR) checklist was additionally consulted in order to ensure a high-quality methodological process, encompassing such elements as an ‘a priori’ design, independent reviews and comprehensive search. The literature search was carried out on PubMed, MEDLINE and Scopus. The search terms used were “Radius fracture AND osteosynthesis”, “Wrist fracture AND external fixator” and “Wrist fracture AND plate”. Two reviewers independently screened titles, abstracts and full texts. To determine inter-reviewer agreement, a k score was calculated after each screening state. Of the 5753 studies collected through the initial databases search, two studies were included in the final meta-analysis (125 treated with external fixator vs 132 with volar plate). There was a substantial inter-reviewer agreement as to the title (0.73; 95% confidence interval, 0.67-0.79) abstract (0.65; 95% CI, 0.46-0.83) and fulltext screening stages (0.89; 95%CI, 0.67-1). The meta-analysis reported a mean difference equal to 0.00 (95%CI= -0.05 – 0.05), in accordance with I²= 0% and p test for the heterogeneity value=0.089. This meta analysis confirms and quantifies that the two techniques are superimposable as regards the quality of life reported by patients at least one year of follow-up.

Surgical Treatment of Distal Radial Fractures with External Fixation Versus Volar Locking Plate: A Multicenter Randomized Controlled Trial

BACKGROUND

The use of volar locking plate fixation (VLP) for unstable extra-articular distal radial fractures has increased in the last decades. External fixation (EF) is less frequently used. This change of surgical approach has only to some extent been evidence-based.

METHODS

In this multicenter, randomized controlled trial, we compared VLP and EF in patients between 18 and 70 years of age who had a displaced extra-articular distal radial fracture (OTA/AO type A3). The patients were examined at 6 weeks, 3 months, and 1 year postoperatively. The primary outcome measure was the Patient-Rated Wrist/Hand Evaluation score (PRWHE). Secondary outcomes were the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), pain score on a visual analog scale (VAS), and radiographic measurements. Range of motion, grip strength, finger stiffness, complications, and reoperations were also recorded.

RESULTS

One hundred and fifty-six patients were included. One hundred and forty-two (91%)-127 women (89%) and 15 men (11%)-completed 1 year of follow-up. Sixty-nine patients were treated with VLP and 73, with EF. The mean age was 56 years. At 6 weeks, the median PRWHE score was significantly higher in the EF group (44) compared with the VLP group (27) (p < 0.001). At 3 months and 1 year, the difference between groups was not significant. The median QuickDASH score was 27 in the VLP group and 43 in the EF group at 6 weeks (p < 0.001), and a significant difference persisted at 3 months (p = 0.023). The VLP group had superior results in terms pain during activity, wrist extension, and ulnar and radial deviation at 1 year, whereas the number of major complications was similar in the 2 groups.

CONCLUSIONS

Patients treated with VLP had earlier recovery of function compared with patients treated with EF. One year postoperatively, we found no significant functional difference.

Analysis of the Clinical and Radiological Results of Bridge Plate Versus External Fixation in Comminuted Distal Radius Fractures

Objective  To evaluate and compare the clinical and radiological outcomes of patients with comminuted distal radius fractures treated with an external fixator or a dorsal bridge plate. Methods  In total, 45 patients were analyzed 1 year after surgery; 18 were treated with an external fixator, and 25 received a dorsal bridge plate. An analog pain scale and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire were applied, in addition to radiographic, strength and range of motion assessments. Statistical analyzes were performed using the chi-squared test and the Mann-Whitney non-parametric test. Results  Fractures were more common in women over 60 years old who suffered falls from their own height. Both methods demonstrated similar functional and radiological results. Infections were more prevalent in patients receiving external fixators, but their residual grip strength was better. Reflex sympathetic neuropathy was more common in subjects treated with a dorsal bridge plate. Conclusion  Our analysis showed no consensus on the superiority of one method over the other. Each method had advantages and disadvantages, but both led to good, similar outcomes. The treatment must be chosen according to the profile of the trauma, the patient's clinical conditions, the surgeon's experience, and the availability of materials.

A comparative study protocol of external fixation versus volar plate in treating distal radius fracture

BACKGROUND

The superiority of the open reduction and internal fixation (ORIF) and external fixation remains uncertain owing to the limited sample size involved in the literature. This retrospective cohort research was implemented for the comparison of the efficiency of ORIF and external fixation utilizing the locked volar plating in treating the intra-articular fractures of distal radius. We hypothesized that compared with the external fixation, ORIF can improve the functional scores and reduce complications.

METHODS

We conducted a retrospective and single-center cohort trial that was approved by institutional review committee of Gansu Provincial Hospital. From June 2016 to July 2018, in our experiment, 178 patients with intra-articular fractures of the distal radius were recruited. Inclusion criteria in this cohort study were designed as follows: the age of patients is between 18 and 65 years, the patients with American Society of Anesthesiologists level I-III, and with the AO-type C3 or C2 fractures of distal radius confirmed by computed tomography scans, the patients with radiographic clinical follow-up for 1 year or >1 year. The patients participating in the trial would be divided into 2 groups: the patients treated via the external fixation and the patients treated by the ORIF utilizing volar plate. The main functional results were the grip strength and the range of motion of wrist. Radiographic measurement and complications were also evaluated in our study.

RESULTS

This study protocol will guide and clarify our assignments, and the final outcomes and conclusion will further enrich the clinical knowledge in the literature.

Volar locking plate versus external fixation for unstable dorsally displaced distal radius fractures-A 3-year cost-utility analysis

Aim

To investigate the cost-effectiveness of Volar Locking Plate (VLP) compared to External Fixation (EF) for unstable dorsally displaced distal radius fractures in a 3-year perspective.

Methods

During 2009–2013, patients aged 50–74 years with an unstable dorsally displaced distal radius fracture were randomised to VLP or EF. Primary outcome was the incremental cost-effectiveness ratio (ICER) for VLP compared with EF. Data regarding health effects (Quality-adjusted life years, QALYs) was prospectively collected during the trial period until 3 years after surgery. Cost data was collected retrospectively for the same time period and included direct and indirect costs (production loss).

Results

One hundred and thirteen patients (VLP n = 58, EF n = 55) had complete data until 3 years and were used in the analysis. At one year, the VLP group had a mean incremental cost of 878 euros and a gain of 0.020 QALYs compared with the EF group, rendering an ICER of 43 900 euros per QALY. At three years, the VLP group had a mean incremental cost of 1 082 euros and a negative incremental effect of -0.005 QALYs compared to the EF group, which means that VLP was dominated by EF. The probability that VLP was cost-effective compared to EF at three years, was lower than 50% independent of the willingness to pay per QALY.

Conclusion

Three years after distal radius fracture surgery, VLP fixation resulted in higher costs and a smaller effect in QALYs compared to EF. Our results indicate that it is uncertain if VLP is a cost-effective treatment of unstable distal radius fractures compared to EF.

Combined Plating of Intra-Articular Distal Radius Fractures, a Consecutive Series of 74 Cases

Background  The distal radius fracture (DRF) is the most common fracture in adults. For unstable intra-articular fractures, the choice of treatment is often operative. The optimal choice of fixation remains a matter of discussion. Question/Purpose  Can combined volar and dorsal plating, using a dorsal frame plate, achieve a good functional and radiographic 1-year outcome in intra-articular DRFs? Methods  In a retrospective cohort study, we evaluated 74 consecutive patients operated with combined plating using a volar plate and a dorsal frame plate. The DRFs were operated between 2016 and 2017 and all cases were AO type C intra-articular fractures. The primary outcome was patient-reported outcome measures including radiographic examination 1 year postoperatively. Secondary outcome measures included wrist range of motion, visual analog scale (VAS) pain scores, and hand grip strength. Results  The median patient-rated wrist evaluation score was 18 points; the quick disabilities of the arm, shoulder, and hand score was 14.8 points. The median Batra radiographic score was 88. Wrist extension was 76% of the uninjured side, flexion was 74%, pronation was 94%, and supination was 94%. VAS pain scores were 0 at rest and 2 during activity. Hand grip strength was 82% compared with the uninjured side. The radiographic outcome according to Batra did not correspond to the patient-reported outcome. Patients older than 60 years had significantly better QuickDASH (quick disabilities of the arm, shoulder, and hand) and PRWE scores (patient-rated wrist evaluation scores) and less pain during activity compared with younger patients despite similar radiographic outcome. There were no tendon ruptures; hardware removal was performed in 21 of the 74 patients. Conclusion  The radiographic outcome did not correspond to the functional outcome 1 year postoperatively. Older patients report less pain and better functional outcome compared with younger patients. There were no tendon ruptures and the frequency of hardware removal was acceptable. Complex intra-articular DRFs AO type C can be managed with volar and dorsal frame-plate fixation to restore distal radius anatomy and achieve a good functional outcome.

A systematic review and meta-analysis of the pronator quadratus repair following volar plating of distal radius fractures

BACKGROUND

Distal radius fracture (DRF) is the most common upper extremity fracture that requires surgery. Operative treatment with a volar locking plate has proved to be the treatment of choice for unstable fractures. However, no consensus has been reached about the benefits of pronator quadratus (PQ) repair after volar plate fixation of DRF in terms of patient-reported outcome measures, pronation strength, and wrist mobility.

METHODS

We searched the PubMed, Embase, Cochrane Central, and China National Knowledge Infrastructure (CNKI) databases up to March 13, 2020, and included randomized-controlled, non-randomized controlled, or case-control cohort studies that compared cases with and without PQ repair after volar plate fixation of DRF. We used a random-effects model to pool effect sizes, which were expressed as standardized mean differences (SMDs) and 95% confidence intervals. The primary outcomes included Disabilities of the Arm, Shoulder, and Hand scores and pronation strength. The secondary outcomes included the SMDs in pain scale score, wrist mobility, and grip strength. The outcomes measured were assessed for publication bias by using a funnel plot and the Egger regression test.

RESULTS

Five randomized controlled studies and six retrospective case-control studies were included in the meta-analysis. We found no significant difference in primary and secondary outcomes at a minimum of 6-month follow-up. In a subgroup analysis, the pronation strength in the PQ repair group for AO type B DRFs (SMD = - 0.94; 95% CI, - 1.54 to - 0.34; p < 0.01) favored PQ repair, whereas that in the PQ repair group for non-AO type B DRFs (SMD = 0.39; 95% CI, 0.07-0.70; p = 0.02) favored no PQ repair.

DISCUSSION

We found no functional benefit of PQ repair after volar plate fixation of DRF on the basis of the present evidence. However, PQ muscle repair showed different effects on pronation strength in different groups of DRFs. Future studies are needed to confirm the relationship between PQ repair and pronation strength among different patterns of DRF.

Management of Distal Radius Fractures: Comparison of Three Methods

Introduction

Distal radius fractures are the most common type of all extremity fractures. It is generally accepted that fractures with more than 2 mm step-off in the radiocarpal joint and greater than 10 degrees dorsal tilt should be treated surgically. However, the ideal technique for surgical management is still a point of debate. We performed cross-sectional data analysis to compare the results of three treatments methods - volar locking plate (VLP), external fixation (EF), Kirschner wire (K-wire) - in patients with distal radius fractures, and compared the clinical, functional, and radiological results

Materials and methods

Forty-four patients with distal radius fractures who underwent fixation with VLP, K-wire or EF between 2011 and 2013 were included in the study. All fractures were classified according to the Müller’s Arbeitsgemeinschaft für Osteosynthesefragen (AO) and Frykman's classifications. Routine radiographs were taken at the postoperative three weeks, six weeks, and three months. Radial inclination, volar tilt, radial length and ulnar variance were assessed on the follow-up visits and additionally at the follow -up for the study. The patient-based Disabilities of the Arm, Shoulder and Hand (DASH) score system and the physician-based MAYO scale were used to evaluate functional outcomes. Radiological and functional outcomes between three surgical modalities were compared and statistically analyzed.

Results

The average age at the time of surgery was 52 years (range = 35-69 years). Of a total of 44 patients, 28 were operated with VLP, 11 were with K-wire and five with EF. Satisfactory reduction was achieved in all fractures, and all of the fractures healed. DASH and MAYO scores were similar in all groups. Regarding radiographic parameters, there was no significant difference in radial inclination, volar tilt, radial length and ulnar variance between the treatment modality groups. When evaluated based on fracture geometry, the DASH score was significantly higher in the patients with AO23A type fracture compared to the patients with AO23B and AO23C type fractures. As for MAYO score, all AO23 groups had similar outcomes.

Conclusions

Surgical treatment options VLP, EF, and K-wire provide adequate fixation, satisfactory radiological, and functional results for the management of distal radius fractures of various severities. The optimal treatment approach depends on individual features, and the choice for an internal fixation or closed reduction method for the restoration of wrist function should be evaluated thoroughly by the operating surgeon considering the patient-related variations.

Necessity of acceptable radiologic alignment by preoperative closed reduction for unstable distal radius fractures treated with volar locking plates

PURPOSE

The purpose of this study was to demonstrate the necessity of achieving acceptable radiographic alignment by preoperative closed reduction in unstable distal radius fractures (DRFs) to improve preoperative pain and obtain satisfactory outcomes after surgery.

METHODS

From 2013 to 2016, patients who received volar locking plates for DRFs were retrospectively reviewed. Patients were classified into acceptable and non-acceptable reduction groups based on immediate post-reduction radiographs. To avoid potential bias, a matched-pair analysis was performed, and paired patients were categorized into non-acceptable reduction (group A) and acceptable reduction (group B) groups. Preoperative pain level, mean length of stay, operation time, postoperative complications, and surgical outcomes were analysed. The preoperative pain level and functional results were assessed by the visual analogue scale (VAS) and Disabilities of the Arm, Shoulder and Hand (DASH) scores.

RESULTS

Of the 239 patients, 80 had non-acceptable and 159 had acceptable reductions. Among these patients, 201 (66 in group A vs. 135 in group B) were matched in a 1:2 matched ratio. Although the radiological parameters after closed reduction were better in group B, there were no significant differences in the preoperative pain VAS score, mean length of stay, operation time, and postoperative complications between the groups. In addition, radiologic parameters and the DASH score at a 1-year follow-up were also not significantly different between the groups.

CONCLUSION

Our results suggest that obtaining acceptable radiologic alignment by closed reduction is not necessary for patients who make an informed decision to undergo volar plating for unstable DRFs.

Safe zone for lateral pin placement for external fixation of the distal humerus

External fixation is a common, efficient technique used for humeral shaft stabilization and elbow fractures. There are reports of radial nerve injuries associated with this procedure. In this study, we investigated the course and variability of the radial nerve along the lateral humerus in relation to the elbow joint to determine a relatively safe zone for lateral pin placement in external fixation. Twenty upper extremities from 10 cadavers were studied. The nerve branches and course of the radial nerve along the lateral humerus were carefully dissected. Straight lines (a, b, and c) were made connecting three landmarks (the acromion, coracoid process, and anterior wall of the axilla) in the proximal upper extremity to the lateral condyle (LC) of the humerus; their intersections with the radial nerve (A, B, and C) were marked. We analyzed whether the intersection positions were correlated with the connecting line lengths. The mean lengths of the connecting lines were (a) 27.24 ± 2.57, (b) 26.18 ± 2.79, and (c) 20.95 ± 1.44 cm; the distance between the intersection points and the LC of the humerus were (Aa) 7.56 ± 1.31, (Bb) 6.90 ± 2.27, and (Cc) 5.01 ± 0.83 cm; and the measured intersection points of the radial nerve in the lateral aspect of the humerus were (A) 18.48%-34.82%, (B) 13.48%-40.00%, and (C) 19.27%-28.05% of the lengths of lines a, b, and c, respectively. Our data provide a more reliable reference to predict the course of the radial nerve on the lateral humerus and define a safe zone for pin placement. Clin.

Management of High Energy Distal Radius Injuries

PURPOSE OF REVIEW

High energy distal radius are commonly multi-fragmentary with significant comminution and/or bone loss. They can also be associated with ligamentous and soft tissue injury and neurovascular compromise. As such, reconstruction of these injuries can be challenging. This paper will review the relevant anatomy, different methods of fixation, and present techniques for difficult fractures.

RECENT FINDINGS

Volar locked plating is a successful, very common method of treatment for distal radius fractures, but dorsal plating, fragment specific fixation, spanning bridge plating, and external fixation are sometimes necessary, particularly in higher energy injuries characterized by metaphyseal comminution, small volar fragments, intra-articular free fragments or lunate facet subsidence. Extended flexor carpi radialis (FCR), dorsal, and flexor carpi ulnaris (FCU) exposures can assist in visualizing the fracture site. There are many different modes of fixation for distal radius fractures, and successful outcome depends on selection of appropriate fixation based on the fracture pattern and status of the soft tissues.
