Pelvic Band
A rigid or semi-rigid component of a hip–knee–ankle–foot orthosis that encircles the pelvis to provide hip joint control and rotational stability.
Full Definition
A pelvic band is the proximal structural element of an HKAFO or hip orthosis, fitted around the iliac crests and lumbar region to anchor the device and control hip abduction, adduction, flexion, extension, and rotation. It is typically fabricated from aluminium alloy or thermoplastic and is connected to the thigh uprights via a hip joint mechanism. In clinical documentation, the pelvic band must be described in terms of its construction material, joint type (free, locked, or limited-motion), and fit landmarks. Editors should distinguish 'pelvic band' from 'pelvic girdle,' the latter being an anatomical term for the bony structure. Mislabelling in device prescriptions can result in incorrect fabrication.
Usage
Usage note: Distinguish from the anatomical term 'pelvic girdle'; in orthotic documents, 'pelvic band' refers exclusively to the device component.
In Context
- "The HKAFO prescription specified a bilateral aluminium pelvic band with drop-lock hip joints set at 0° of abduction." — Orthotic device prescription
- "Revise 'pelvic girdle' to 'pelvic band' throughout Section 3; the author is describing the orthotic component, not the anatomical structure." — Copyediting note for rehabilitation textbook
