Tenodesis Splints: Types, Indications, and Patient Guidance

A tenodesis splint is a rigid orthosis that immobilizes a joint to promote healing, reduce pain, or correct deformity. Materials include thermoplastic, fiberglass, or plaster.

Common Indications

• Arthritis (joint rest)
• Tendonitis / tenosynovitis
• Fractures (non‑operative or post‑operative)
• Dislocations / subluxations
• Sprains (severe)
• Neuromuscular weakness (e.g., radial nerve palsy)

Examples by Joint

• Wrist – positions wrist in slight extension to optimize finger flexion via tenodesis effect.
• Knee – extension splint for quadriceps inhibition or fracture immobilization.
• Elbow – flexion/extension control post‑trauma.

Wear & Care

• Typically worn 3–12 weeks per physician protocol.
• Monitor for skin breakdown, pressure sores, stiffness.
• Remove for hygiene and prescribed exercises.

Risks

• Skin irritation / pressure injury
• Joint stiffness / contracture
• Muscle atrophy from disuse

Always follow the prescribing clinician's wearing schedule and follow‑up.
