Pinning the Thumb Carpometacarpal Joint in Abduction Can Reduce Skin Irritation from Suzuki Frame Treatment for Metacarpophalangeal Joint Fractures.
Case Report
Comminuted intra-articular fractures of the metacarpophalangeal joint (MCPJ) of the thumb are difficult to treat because of challenges with anatomical fixation. The pins and rubbers traction system (PRTS), described by Suzuki et al., is a minimally invasive technique that enables early range-of-motion training while maintaining joint congruency. PRTS exhibits advantages relative to other dynamic external fixation techniques due to its simplicity, low cost and compact design. It has been used mainly in treating primarily proximal interphalangeal joint (IPJ) fractures. We present two patients where we used a PRTS for comminuted intra-articular fractures of the thumb MCPJ with good outcomes. We temporarily pinned the carpometacarpal joint (CMCJ) in maximum abduction to avoid skin irritation from the ulnar aspect of the axial traction wire in thumb adduction. Level V (Therapeutic).
