PO-16-a · Ambulation Aids

Ambulation Aids. Topics: Canes, Crutches, Walkers, and Weight-Bearing Status. Part of the Prosthetics & Orthotics series of the Reflex PM&R Board Review podcast. Audio correction: In the audio: the interphalangeal joints, the IP joints, held in slight flexion of 10 to 20 degrees, — Correct: In the resting hand (safe position) splint the IP joints are held in full extension. This is the intrinsic-plus position: the MCP collaterals are taut in flexion so the MCPs are flexed, while the IP collaterals and volar plate shorten in flexion so the IPs are held straight. Holding the IPs flexed produces the PIP flexion contracture the splint exists to prevent. The written chapter is correct. Full correction register: https://www.reflexpmr.com/errata.
