RESUMO
INTRODUCTION: Unstable proximal phalanx fractures are relatively common injuries but consensus of standard treatment is lacking. Outcomes following plate fixation are highly variable, and it remains unclear which factors are predictive for poorer results. The purpose of this study was to compare dorsal and lateral plate fixation of finger proximal phalangeal fractures with regard to factors that influence the outcome. MATERIALS AND METHODS: A retrospective chart review of proximal phalanx fractures treated with dorsal and lateral plating over a 6-year study interval was performed. Demographic data and injury-specific factors were obtained from review of clinic and therapy notes of 42 patients. Fractures were classified based on the OTA classification using preoperative radiographs. Outcomes investigated included final range of motion (ROM) and total active motion (TAM) of all finger joints. Complications and revision surgeries were also analyzed. RESULTS: Fracture comminution, dorsal and a lateral plate position, occupational therapy, and demographic factors did not significantly influence the outcome, complication, and revision rate after plate fixation of finger proximal phalangeal fractures. CONCLUSIONS: Based on the results of this study, no differences in the outcome of finger proximal phalangeal fractures treated by both dorsal and lateral plate fixation were observed. LEVEL OF EVIDENCE: Therapeutic, retrospective comparative, level III.

Background Extra-articular fractures of the distal radius are often treated with a trial of nonoperative management if radiographic parameters are within an acceptable range, especially in the elderly population. Unfortunately, some malunions become symptomatic or become grossly misaligned during nonoperative management which require corrective surgery to restore the normal osseous anatomy and restore function. Description of Technique We describe correction of a distal radius malunion utilizing a distraction-type volar osteotomy, a volar plate specific distraction device, and a novel resorbable calcium phosphate bone cement (Trabexus) designed to withstand compressive loads. Patients and Methods Twelve patients with 13 distal radius fractures were included in this study. The average patient age was 60.9 years and average time from injury to corrective osteotomy was 96.3 days. Radiographic measures (radial inclination, volar tilt, and ulnar variance) and clinical assessment (wrist/forearm range of motion and grip strength) were done pre- and postoperatively and compared. Results The average time from corrective surgical osteotomy to final clinical follow-up was 375.8 days. After surgical intervention, there was a statistically significant improvement in mean volar tilt (-19.8 vs. +0.5 degrees) and mean ulnar variance (+2.8 vs. -0.4 mm). Improvements were also seen in grip strength (1.7 vs. 43.6 lb), wrist flexion (30.5 vs. 48.3 degrees), wrist extension (33.3 vs. 53.8 degrees), forearm pronation (75.0 vs. 88.8 degrees), and forearm supination (53.8 vs. 81.3 degrees). On average, 56.0% of Trabexus bone substitute remained on final clinical radiographs. Conclusion This simplified technique of distraction corrective osteotomy after distal radius malunion results in improved clinical and radiographic outcomes for patients.
RESUMO
SUMMARY: One of the most versatile soft-tissue flaps available for elbow coverage that is reliable, quick, and easy to perform, with minimal donor defect and without the sacrifice of a major blood vessel, is the antegrade posterior interosseous artery flap. A large amount of vascularized fascia can be dissected with the flap, and it can be useful in lining the elbow joint or any exposed implant(s). After flap harvest, the donor site is often amenable to primary closure or requires a simple skin graft for closure. This article explains the technique for harvesting an antegrade posterior interosseous artery flap and describes 10 cases in which the flap was used for complex soft-tissue defects of the elbow not amenable to local wound care or skin grafting.
