A Dynamic Approach to Managing Unstable Proximal Interphalangeal Joint Fractures: The Suzuki Frame
,
Abstract
Background: This study aimed to investigate the clinical and radiological outcomes in unstable proximal interphalangeal joint (PIPJ) fracture-dislocations using the Suzuki frame.
Methods: 21 patients (mean age: 33.14 years) with unstable fractures of the PIPJ were treated with a Suzuki frame. The mean interval between injury and surgery was 6.14 days. Early active range of motion (ROM) of all fingers was encouraged immediately after surgery. Patients were followed closely for the first two weeks, and clinical and radiological outcomes were measured at the final follow-up.
Results: Frames were removed at 6 weeks, with all fractures achieving union and stable, congruent PIPJ. One patient developed a pin-tract infection, resolved with antibiotics. Mean PIPJ ROM was -7.85° extension to 75.7° flexion; distal interphalangeal joint (DIPJ) ROM was -8.5° extension to 40.0° flexion. Mean grip strength was 13.5 kg, and mean visual analogue scale (VAS) pain score was 0.6. Early surgery (< 7 days) was associated with better DIPJ flexion (P = 0.008) and lower pain scores (P = 0.029).
Conclusion: The Suzuki frame is a convenient, inexpensive, and effective system to manage difficult unstable PIPJ fracture- dislocations.
