Humeral Cast Brace for Arm Extension Fixation: A Concise Overview

Humeral Cast Brace Indications & Application

A humeral cast brace (or sugar‑tong splint) provides temporary immobilization from the shoulder to the distal forearm, maintaining the elbow in extension.

Typical Uses

• Distal humerus fractures (non‑operative or post‑op protection).
• Supracondylar fractures in children (after closed reduction).
• Elbow dislocations (post‑reduction stabilization).
• Post‑operative protection after ORIF or total elbow arthroplasty.

Key Features

• Molds to anatomy; allows swelling accommodation.
• Permits shoulder motion (pendulum exercises) while restricting elbow flexion/extension and forearm rotation.
• Adjustable straps for compression and fit.

Clinical Pearls

• Monitor neurovascular status (radial pulse, capillary refill, median/radial/ulnar nerve function) q1–2h initially.
• Educate patient on signs of compartment syndrome.
• Transition to functional brace or hinged orthosis as healing progresses.
