Residual Limb Contracture
A permanent shortening or tightening of muscles, tendons, or soft tissue around a residual limb that limits joint range of motion and complicates prosthetic fitting.
Full Definition
Residual limb contracture occurs when soft tissue structures adjacent to an amputation site undergo adaptive shortening due to disuse, improper positioning, or scar tissue formation. The condition most commonly manifests as hip flexion contracture in transfemoral amputees or knee flexion contracture in transtibial amputees, both of which significantly impair prosthetic alignment and gait quality. Clinically, even a modest contracture of 15–20 degrees can render prosthetic fitting difficult or impossible without surgical intervention. In editorial contexts, the term should not be hyphenated and should be clearly distinguished from 'residual limb edema,' which is a volume change rather than a structural change. Clinical documentation must specify the affected joint, degree of contracture, and whether passive correction is achievable.
Usage
Usage note: Always specify the affected joint (e.g., 'hip flexion contracture') for clinical precision; avoid the lay term 'stump stiffness' in formal documentation.
