Dorsal Approach for Management of Proximal Interphalangeal Joint Flexion Contracture.

Proximal interphalangeal (PIP) joint contracture is a common, difficult clinical problem that can arise from minor trauma. Management is difficult because outcomes are unpredictable and often poor, due to residual flexion deformities postoperatively. The dorsal approach for flexion contracture of the PIP joint is not discussed in present literature. In this technique guide, we wish to describe and explain the rationale for a dorsal approach. In our experience, a dorsal approach allows for ease of access to all pathologic structures, with simple positioning of the digit to allow access to volar structures, as well as when addressing more than one digits with a PIP contracture. Finally, similar to the midaxial approach, the dorsal approach also eliminates any volar soft tissue concerns and need for supplemental coverage.
