Prime Elbow System

Pre-assembled Range of Motion Elbow System

Available pre-fabricated, custom-to-measurements, and custom-to-cast

The unique prefabricated Prime® modular elbow system is effective for many upper extremity indications. Its lightweight, comfort, and adjustable range of motion joints facilitate application in clinical or office settings with a minimum of tools.

The upper and lower arm sections are modular, allowing interchangeability to meet specific patient size requirements. The standard orthosis includes an adjustable anodized aluminum lateral joint and a single-axis plastic medial joint for stability. A medial adjustable joint is available as an option.

The lower arm component can be a wrist-hand design or an ulnar sleeve with no wrist-hand extension, depending on the need to limit rotation at the elbow.

The orthosis has been found effective for, among other indications, olecranon fractures, proximal radial/ulnar fractures, following surgery for Type III elbow injuries, and postoperatively following elbow arthroplasty.

Ease of application/removal facilitates sock/dressing changes and wound inspection. Lightweight and durability encourage longer-term wear and patient compliance.

The Prime can also be fabricated custom-to-measurements for same-day shipment or custom-to-cast for same-day shipment the day the negative cast is received.
