Evaluation of Suzuki Frame Fixation in Comminuted Fractures of the Proximal Interphalangeal Joint.

Overview

This prospective randomized controlled trial aims to evaluate the functional and radiological outcomes of using the Suzuki frame for treating comminuted intra-articular fractures of the proximal interphalangeal (PIP) joint. The study involves adult patients with PIP joint fractures who will be treated using dynamic joint distraction (ligamentotaxis) via the Suzuki frame. The primary goal is to assess whether this technique facilitates early active finger motion, reduces joint stiffness, and improves long-term functional recovery compared to other methods.

Fractures involving the proximal interphalangeal (PIP) joint are challenging to manage, often leading to pain, stiffness, and functional impairment. Dynamic joint distraction using ligamentotaxis has emerged as an alternative to open surgery to facilitate early mobilization while avoiding the risks of soft-tissue dissection. In this study, we are investigating the short-term functional and radiological outcomes of the Suzuki frame, which utilizes a 1.2-mm Kirschner wire axial traction pin and a hook pin connected by rubber bands to maintain joint congruency. Participants will include adults with isolated, comminuted intra-articular PIP joint fractures. Patients will be monitored over a 6-month follow-up period. Clinical evaluation will include the Visual Analogue Scale (VAS) for pain and the QuickDASH score for functional disability. Radiological assessment will focus on joint alignment and reduction. The study will be conducted at Sohag University Hospital, following an intention-to-treat analysis principle.
