Complications of Volar Locked Plating of Distal Radius Fractures: A Prospective Investigation of Modern Techniques

Clinical and Radiographic Outcomes Following Volar-Locked Plating Versus Dorsal Bridge Plating for Distal Radius Factures

Purpose

Distal radius fractures (DRFs) indicated for operative intervention are most commonly treated with volar-locked plating (VLP); however, dorsal bridge plating (DBP) has been used as an alternative fixation method. The purpose of this study was to use a propensity score to match and compare the radiographic and clinical outcomes of patients undergoing isolated VLP or DBP for DRFs.

Methods

We performed a retrospective, propensity score-matched analysis of patients undergoing isolated VLP or DBP treatment for isolated DRFs from 2015 to 2022 at a single level-1 trauma center. Patients were propensity score-matched by a total of eight demographic and comorbidity factors, AO Foundation/Orthopedic Trauma Association classification, and preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) scores. Our primary outcomes included postoperative complications, wrist and forearm range of motion (ROM), grip strength, and radiographic measurements, including radial height, radial inclination, volar tilt, and articular step-off.

Results

Overall, 415 DBP and 2075 VLP were successfully propensity score-matched and included in this study. Grip strength and ROM measurements at the 6-month follow-up, including wrist flexion, wrist extension, forearm pronation, forearm supination, radial deviation, and ulnar deviation, were increased in the VLP compared with DBP (P < .05). Complication rates among both the groups were relatively low; however, the rates of malunion and nonunion were significantly higher among the DBP group (P < .05). Radial height, radial inclination, and articular step-off were improved in the VLP group compared with the DBP group (P < .05); however, volar tilt was similar between groups. PROMIS upper extremity and physical function were significantly higher among the VLP group (P < .05). No significant difference was noted in PROMIS pain interference between the groups.

Conclusions

When compared with DBP, patients undergoing VLP are more likely to have improved clinical and radiographic outcomes. Although improvement in wrist and forearm ROM and radiographic parameters is statistically significant, it may not be clinically relevant.

Efficacy of cast immobilization versus surgical treatment for distal radius fractures in adults: a systematic review and meta-analysis

This articl e includes high-quality randomized controlled trials in recent years and updates the past meta-analysis. It has been proved that cast immobilization can achieve similar functional results, reduce economic burden in the long-term compared with surgery, and provide a basis for doctors to make treatment choices.

PURPOSE

The efficacy of conservative and surgical treatment of distal radius fractures (DRFs) in adults is still controversial. Recently, some high-quality randomized controlled trials (RCTs) evaluated the efficacy of both treatments. We hypothesized that treatment of DRFs with closed reduction and cast immobilization would achieve functional outcomes similar to surgery.

METHODS

This study is a systematic review and summary of RCTs comparing conservative and surgical management of DRFs from 2005 to March 2022. Patients were evaluated for functional and imaging outcomes and complications.

RESULTS

A total of 11 studies [1-11] included 1775 cases of DRFs. At 1-year follow-up, the cast group had lower mean differences (MDs) in DASH scores than the surgery group by - 2.55 (95% CI =  - 5.02 to - 0.09, P = 0.04); with an MD of 1.63 (95% CI = 1.08-2.45, P = 0.02), while the surgery group had a lesser complication rate than the cast group.

CONCLUSIONS

At 1-year follow-up, the lower DASH scores of the cast group showed advantages of this treatment, but the complication rate was higher than that of the surgery group. There was no massive distinction in other scoring methods.

Operative Treatment of Distal Radius Fractures in Patients With Parkinson Disease

BACKGROUND

Owing to the many unique disease characteristics of Parkinson disease (PD)-namely resting tremors, muscular rigidity, and poor bone quality-we hypothesized that this patient population would have inferior outcomes with surgical management of acute distal radius fractures (DRFs) compared with the literature available on the general population.

METHODS

This is a retrospective observational study performed at a single, level 1, academic center from 2001 to 2020 capturing all adult patients with an isolated, acute, and closed DRF that ultimately underwent operative treatment. International Classification of Diseases 10 codes were used to identify 30 patients for manual chart review. Several patient and fracture characteristics were accounted for and complications, reoperations, and failures of surgical intervention were recorded.

RESULTS

There was a total of 7/30 failures (23%), 6/30 reoperations (20%), and 12 complications in 9/30 wrists (complication rate, 30%) at a mean latest follow-up of 11 months (1.2-158 months). Of the 7 failures, 5 were due to loss of reduction, and 2 of them were deep infections with mean time to failure of 8.3 weeks (range, 11 days-5.2 months).

CONCLUSIONS

This study found a high rate of complications, reoperations, and early failure despite a short follow-up period and a small cohort of patients with PD treated surgically for a DRF. We recommend locked plating if suitable for the fracture type and early involvement of a multidisciplinary team to assist with medical optimization of PD to increase chances of a successful outcome.

Risk Factors for Complications following Volar Locking Plate (VLP) Fixation of Unstable Distal Radius Fracture (DRF)

Objective

To evaluate the incidence and risk factors for complications following volar locking plate (VLP) fixation of unstable distal radius fracture (DRF).

Methods

This retrospective study identified patients who underwent VLP fixation of unstable DRF between 2017 and 2020 with a minimum 12-month follow-up assessments. By reviewing electronic medical records and follow-up notes, patients were categorized complication or noncomplication group. Differences in variables were detected by using univariate analyses, and independent factors were identified using multivariate logistic regression analysis.

Results

During this study period, 423 patients were included, and 63 (rate, 14.9%) complications in 58 patients were documented. Wound infection (17, 4.0%) was most common, followed in decreasing frequency by carpal tunnel syndrome (13, 3.1%), tendon rupture/irritation (10, 2.4%), complex regional pain syndrome (8, 1.9%), and plate/screw-related complications (5, 1.7%). In the univariate analyses, 18 variables were found to be significantly different (p < 0.05). Logistic regression analysis identified 5 independent factors, including being male (OR, 3.5; p = 0.014), type C fracture (vs. type A, OR: 2.7, and p = 0.035), general anesthesia (vs. regional, OR: 2.4, and p = 0.045), bone grafting (OR, 6.3; p < 0.001), and surgery performed by less experienced surgeons (OR, 3.1; p = 0.003). The goodness-of-fit of the final model was acceptable.

Conclusions

These factors will help surgeons individualize and stratify the risk of complications and help patients for risk counselling; especially, an informed clinical decision targeting those modifiable factors (anesthesia mode, bone grafting, and surgeon experience) can be considered, when indicated.

SAFETY AND RELIABILITY OF CARBON-PEEK PLATE FOR THE TREATMENT OF DISTAL RADIUS FRACTURES: A REVIEW OF THE LITERATURE

INTRODUCTION

Distal radius fractures are one of the most common injuries. Open reduction and internal fixation (ORIF) are the most diffused between surgical treatments. Carbon-fiber reinforced (CFR) polyetheretherketone (PEEK) plates have been proposed to prevent effects linked to stainless steel or titanium alloy traditional plates, such as radio-opacity, mismatch of bone-plate elasticity modulus, corrosion, limited fatigue life, osseointegration.

OBJECTIVE

This review aims to evaluate the actual safety and reliability of CFR- PEEK plates to treat distal radius fractures.

METHODS

Electronic databases PubMed, Google Scholars, and Cochrane Library were searched in December 2020. Eligible studies were published in peer-reviewed journals. Three authors independently selected relevant articles and discussed those. Searching identified 13 titles and abstracts, 11 manuscripts were considered eligible for the full-text analysis. Of these 11 papers, 7 studies were included in our review.

RESULTS

215 patients were analyzed in this systematic review. The mean age of enrolled patients was 52,8 years. 34% were males and 66% were females. Fractures were classified according to AO/ASIF classification system. We reported 12 cases of complications specific to this device, such as intraoperative plate and screws rupture, erosive flexor tendons synovitis, and loosening.

CONCLUSION

CFR-PEEK distal radius plates are potentially an alternative to traditional ones. But we believe that the use of this device does not entail a significant advantage in the treatment of distal radius fractures, as safe and low-cost traditional devices are available. Further comparative studies are needed to demonstrate the superiority of carbon devices.

Complications of Volar Plating of Distal Radial Fractures: A Review

Although the overall complication rate of volar plating approaches 15%, less than 5% require reoperation. Certain factors involving the patient, the fracture, and/or the surgeon may affect the overall complication risk. Patient factors, including body mass index greater than 35 and diabetes mellitus, may increase complication risk with volar plating, but older patient age does not seem to significantly alter risk.

Common Complications of Distal Radial Fractures

Distal radial fractures are associated with good outcomes; however, although they occur at low rates, complications can significantly impair treatment success. Therefore, the treating surgeon should be aware of potential complications associated with each treatment type and how to best prevent them. Although certain patient-specific and fracture-specific factors may increase the risk of adverse outcomes, most are nonmodifiable risk factors at the time of presentation, so it is imperative that every effort is made to mitigate these risk factors to prevent long-term morbidity. Patients should be well-informed about these complications and potential symptoms so that they can be addressed expeditiously.

Dorsal Bridge Plate for Distal Radius Fractures: A Systematic Review

PURPOSE

This study presents patient demographics, injury characteristics, outcomes, and complications associated with dorsal bridge plating (DBP) in the treatment of distal radius fractures.

METHODS

A literature search performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines identified 206 articles, 12 of which met inclusion criteria, accounting for 310 patients. Included articles contained the results of DBP for treatment of distal radius fractures with reported outcomes between 1988 and 2018. Data were pooled and analyzed focusing on patient demographics, as well as 3 primary outcomes of complications, range of motion (ROM), and Disabilities of the Arm, Shoulder, and Hand (DASH) and QuickDASH scores.

RESULTS

Average age was 55 years, median follow-up was 24 months, and the most common use was in comminuted (92%) intra-articular (92%) distal radius fracture caused by fall (58%), or motor vehicle collision or motorcycle collision (27%). A minority of patients had open fractures (16%) and most were cases of polytrauma (65%). Median time from placement to DBP removal was 17 weeks (mean, 119 days). At final follow-up, mean wrist ROM was 45° flexion, 50° extension, 75° pronation, and 73° supination. Mean DASH score was 26.1, and mean QuickDASH score was 19.8. The overall rate for any complication was 13%; the most common was hardware failure (3%) followed by symptomatic malunion or nonunion (3%), and persistent pain after hardware removal (2%).

CONCLUSIONS

Dorsal bridge plating was found to be used most commonly in intra-articular, comminuted distal radius fractures with overall functional wrist ROM, moderate patient-reported disability, and a 13% complication rate at follow-up.
