Non-bridging external fixation employing multiplanar K-wires versus volar locked plating for dorsally displaced fractures of the distal radius
ABSTRACT BACKGROUND: The aim of this study was to compare non-bridging external fixation to palmar angular stable plating with respect to radiological outcome, wrist function, and quality of life. METHODS: One hundred and two consecutive patients (mean age: 63 years) were enrolled in the study. Fifty-two patients were randomized for plate osteosynthesis (2.4 mm, Synthes), 50 patients received non-bridging external fixation (AO small fixator). Objective (range of motion, grip strength), patient rated outcomes (quality of life, pain), and radiological outcome were assessed 8 weeks, 6 months, and 1 year after surgery. RESULTS: Loss of radial length of more than 3 mm was not detected in any group. Volar tilt was better restored by external fixation (7.2°) than by volar plating (0.1°). Wrist function was good in both groups. The external fixator was tolerated very well, and the quality of life assessment revealed comparable results in both groups. Osteoporosis was found in 54 % of patients and had no influence on radiological and functional outcome. CONCLUSION: Non-bridging external fixation employing multiplanar K-wires is a suitable treatment option in intra- and extra-articular fractures of the distal radius even in osteoporotic bone. LEVEL OF EVIDENCE: Prospective randomized trial, Level I.

ABSTRACT: INTRODUCTION: Palmar plate fixation of unstable distal radial fractures is quickly becoming the standard treatment for this common injury. The literature reporting complications consists mainly of isolated case reports or small case series. METHOD: Between February 2004 and December 2009 palmar plate fixation was performed in 665 cases. The overall complication rate was 11.3 % (75 complications). Revision surgery was necessary in 10 % (65 procedures). RESULTS: The reasons for revision surgery were: postoperative median nerve compression (22 patients) and secondary dislocation (9 patients). An ulna shortening osteotomy for ulnar impingement syndrome was necessary in eight cases. Intraarticular screw placement occurred in three patients. There were two flexor pollicis longus, one finger flexor and three extensor pollicis longus tendon ruptures. Posttraumatic compartment syndrome of the forearm requiring fasciotomy occurred in four cases. There were three cases of infection. Nonoperative treatment was necessary in nine patients, who developed a complex regional pain syndrome. Hardware failure occurred in three cases. Hardware removal was performed in 232 (34 %) cases. CONCLUSION: Palmar plate fixation of distal radius fractures is a safe and effective procedure. Nevertheless, complications necessitating a second intervention are relatively common. A proportion of these complications is iatrogenic and can be avoided by improving the surgical technique.Archives of Orthopaedic and Trauma Surgery 05/2013; 133(8).

ABSTRACT: The choice between volar locking plates (VLP) and external fixation (EF) for unstable distal radius fractures have not reached a consensus. The meta-analysis of randomized controlled trials was performed to compare VLP with EF to determine the dominant strategy.Journal of Surgical Research 06/2014; 193(1).

ABSTRACT: Background The objective of the study was to compare the efficacy of external fixation and volar plating on the functional parameter of displaced intra-articular (Cooney’s type IV) distal end radius fractures using the Green and O’Brien scoring system. Materials and methods This prospective randomized study comprised 68 patients treated with external fixation and 42 patients treated with volar locking plates. The patients were followed up at 6 months and 1 year after surgery. The assessment of pain, range of motion, grip strength and activity were assessed at each follow-up visit and scored according to the Green and O’Brien scoring system. Results At 1 year after surgery, we observed that external fixation showed significantly better results than volar locking plates using the Green and O’Brien scores for range of motion (22.0 ± 4.77 vs 19.89 ± 5.05), grip strength (19.91 ± 5.4 vs 16.89 ± 4.4) and final outcome (87.36 ± 11.62 vs 81.55 ± 11.32). No difference was found in pain and activity between these two groups of patients. Patients aged <50 years treated with external fixation showed excellent results (final score (91.57 ± 9.01) at 1 year follow-up. Conclusion External fixation showed superiority over volar locked plating after 1 year of surgery. Level of evidence IV.Journal of Orthopaedics and Traumatology 09/2014; 15(4).
