Observations on autopsy specimens. Ritt MJ. Bos KE. Clinical Orthopaedics & Related Research. [JC:dfy] (292):172-6, 1993 Jul. A new method for internal fixation using power-driven staples was recently developed. In theory, this new technique should be ideal in performing small joint arthrodesis. In autopsy specimens, the biomechanical properties were observed in simulated proximal interphalangeal joint arthrodesis (PIP). The tension-band technique, acting as a control, was significantly superior. The two techniques had similar biomechanical properties. The three 7- x 7-mm staples is recommended. The tension-band technique remains the technique of choice in small joint arthrodesis.
