Scaphoid fractures treated with a volar percutaneous approach. Analysis and results in 92 cases

Abstract

ObjectiveHerbert type B1 and B2 scaphoid fractures can be treated by orthopaedic treatment or surgery. The aim of this study is to analyse results and complications of scaphoid waist fractures treated using the percutaneous volar approach. Material and methodWe present a retrospective study of 92 patients, treated in our institution from 2006 to 2016 using a volar percutaneous fixation. Mean Follow-up was 16 months (range 12–48). Injuries were classified using Hebert's classification, including B1 and B2 fracture types; the other fracture types following this classification system were excluded. Polytrauma patients, dorsal approach, fractures associated with distal radius injuries, patients treated using another surgical technique and patients with non follow-up were also excluded. Functional results were evaluated using the DASH questionnaire. Consolidation was established as the presence of bony bridges crossing the fracture site on X-rays, associated with absence of pain. ResultsThe average time to fracture healing was 6.6 weeks (range 5–11). After 12 months of follow-up, the average wrist range of motion was 70° of extension (range 58–75) and 70° of flexion (range 62–80). Regarding functional evaluation, the average DASH questionnaire score was 42. The most frequent complication was non-union in 4 cases (4.44%). Average surgical time was 25min. ConclusionsVolar percutaneous fixation is a simple and quick technique for a specialist surgeon, characterised by low morbidity and complication rates compared to ORIF and orthopaedic treatment, which accelerates the patient's functional recovery.
