A Novel 5-pin Fixation for Distal Radius Fractures and Its Functional Assessment

Abstract

Background: Distal radius fractures are an extensively debated topic throughout decades. The treatment options include POP casting, plating, external fixation with or without ligamentotaxis, and K -wiring. This study was conducted to assess the functional outcome of a novel percutaneous 5-pin technique in distal radius fractures. Materials and methods: This is a prospective observational study over 16 months from January 2019 to May 2020. Novel percutaneous 5-pin technique in a sequential configuration following a closed reduction was performed, followed by physiotherapy, and functional outcome was assessed at 6, 12, and 28 weeks following K -wire removal using Cooney’s modification of Green and Obrien scoring and evaluated for functional status, pin loosening, tendon impalement, and nerve injury. Results: All 20 patients were assessed. The mean age of patients was 47.15 years, 10 being females, with road traffic accidents being the major mode of injury. All patients were followed up for 6 months post- K -wire removal and 90% of patients had good to the excellent outcome and 10% of patients had fair to bad outcome with a functional range of supination and pronation movements. All fracture unions were satisfactory and four patients (20%) developed minor complications. None of them developed tendon impalement or nerve injuries. Conclusion: The novel percutaneous 5-pin technique includes two additional ulnoradial wires which provide superior rotational stability and avoid the chance of late collapse and maintain radial height, unlike conventional K -wire techniques. Thus, avoiding the need for more invasive techniques and allows early mobilization of wrist and fingers preventing stiffness, resulting in an excellent outcome.
