PROXIMAL INTERPHALANGEAL JOINT ARTHRODESIS USING POWERED STAPLE FIXATION - OBSERVATIONS ON AUTOPSY SPECIMENS

A new method for internal fixation using power-driven staples was rece ntly developed. In theory, this new technique should be ideal in perfo rming 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, wa s significantly superior. The two techniques had similar biomechanical properties. The three 7- x 7-mm staples is recommended. The tension-b and technique remains the technique of choice in small joint arthrodes is.
