Comparison of angle stable plate fixation approaches for distal radius fractures.
ABSTRACT The aim of the study was to compare radiological and functional outcomes between volar and dorsal surgical fixation of distal radius fractures using low-profile, fixed-angle implants.
A total of 305 distal radius fracture patients were treated with Synthes locking compression plate (LCP) 2.4- or 3.5-mm fixation using either a volar (n=266) or dorsal (n=39) approach. The patients were examined at 6 months, 1 and 2 years for radiological assessment of fracture healing, alignment, reduction and arthritis, as well as the determination of various functional outcome scores.
Both groups were comparable with respect to baseline and injury characteristics. The complication rate was higher for the volar approach (15%). No significant differences were observed for Disabilities of the Arm, Shoulder and Hand (DASH) and Short Form (36) Health Survey (SF-36) scores, pain, arthritis grade, grip strength and radiological measurements. However, a significantly better functional outcome represented by a low mean Gartland and Werley score was observed for the volar approach after 6 and 12 months. Significantly higher percentages of dorsal extension, palmar flexion, ulnar deviation and supination angle (relative to the mean contralateral healthy wrist) were also reported for volar approach patients at the 6-month follow-up.
Volar internal fixation of distal radius fractures with LCP DR implants can result in earlier and better functional outcome compared with the dorsal approach, yet is associated with a higher incidence of complications. After 2 years, these differences are no longer observed between the two surgical methods.

ABSTRACT: Small variations within normal range of radiographic parameters, except ulnar variance and volar tilt, do not influence the final functional outcome in distal radius fractures. There are many reports in the literature on the relationship between radiographic variables and their influence on the final outcome of distal radius fractures. Most authors report that a good functional result depends on anatomical restoration of the articular surface and extra-articular alignment. The aim of this study was to verify if it is really necessary to restore anatomic radiographic parameters to obtain satisfactory functional outcome in distal radius fractures treated with volar plate. We retrospectively evaluated 51 patients treated with volar locked plate for articular unstable distal radius fractures from December 2006 to March 2009. Each fracture was evaluated according to the AO classification. The average follow-up was 40.5 months. Radiological measurements were performed considering radial height, radial inclination, volar tilt and ulnar variance, both preoperatively and postoperatively, to estimate the correction value. We examined range of motion (ROM), grip strength with a Jamar(®) dynamometer and Disabilities of the Arm, Shoulder and Hand (DASH) score. The τ Student test was performed for statistical analysis. The persistence of articular step-off was assessed in 35.3% of patients. Normal radial inclination (21-25°) was restored in 74.5% of patients (range 15-27.5°). Normal radial height (10-13mm) was restored in 66.6% of patients (range 6.8-17.3mm). Normal volar tilt (7-15°) was achieved in 90.2% of patients (range 3-17°). Normal ulnar variance (0.7-1.5mm) was restored in 86.3% of patients (range 0.7-4.1mm). There was a statistically significant difference between the preoperative and postoperative radiographic values (p<0.01). The majority of patients showed complete recovery of ROM, with no statistically significant difference (p>0.05) in extension, flexion, supination and pronation compared with the contralateral hand. Eight patients who had postoperative volar tilt and/or ulnar variance out of range had a statistically significant difference (p<0.05) in ROM compared with the non-operated side. At final follow-up, all patients had a statistically significant difference (p<0.05) in grip strength compared with the contralateral side, even with good strength values. The mean DASH score was 12.2 (range 0-61). Our experience suggests that ulnar variance and volar tilt are the most important radiographic parameters to be restored to obtain good functional outcome in distal radius fracture. Small variations of other radiographic parameters seem to not affect the final outcome at minimum 3 years' follow-up. Copyright © 2014 Elsevier Ltd.

ABSTRACT: The Royal College of Surgeons of England (RCS) has issued guidance regarding the use of reoperation rates in the revalidation of UK-based orthopaedic surgeons. Currently, little has been published concerning acceptable rates of reoperation following primary surgical management of orthopaedic trauma, particularly with reference to revalidation. A retrospective review was conducted of patients undergoing clearly defined reoperations following primary surgical management of trauma between 1 January 2010 and 31 December 2011. A full case note review was undertaken to establish the demographics, clinical course and context of reoperation. A review of the imaging was performed to establish whether the procedure performed was in line with accepted trauma practice and whether the technical execution was acceptable. A total of 3,688 patients underwent primary procedures within the time period studied while 70 (1.90%, 99% CI: 1.39-2.55) required an unplanned reoperation. Thirty-nine (56%) of these patients were male. The mean age of patients was 56 years (range: 18-98 years) and there was a median time to reoperation of 50 days (IQR: 13-154 days). Potentially avoidable reoperations occurred in 41 patients (58.6%, 99% CI: 43.2-72.6). This was largely due to technical errors (40 patients, 57.1%, 99% CI: 41.8-71.3), representing 1.11% (99% CI: 0.73-1.64) of the total trauma workload. Within RCS guidelines, 28-day reoperation rates for hip, wrist and ankle fractures were 1.4% (99% CI: 0.5-3.3), 3.5% (99% CI: 0.8%-12.1) and 1.86% (99% CI: 0.4-6.6) respectively.
