hip abduction orthosis

Full Definition

A hip abduction orthosis is a therapeutic device that positions the hips in abduction and flexion to promote proper hip development or maintain reduction after treatment. Common types include the Pavlik harness for DDH, the Rhino brace, and various rigid abduction orthoses. The device works by maintaining the femoral head in optimal position relative to the acetabulum, promoting normal hip development and preventing re-displacement.

Usage

Usage note: Generic term; specify brand or type (Pavlik, Rhino, etc.) when relevant for treatment documentation.
