What condition is commonly associated with immobilization of IP joints after surgery or edema/trauma?

• A. Flexion contractures
• B. Hyperextension
• C. Dislocation
• D. Fracture

Answer: (A)

When finger joints are immobilized, the tissues that cross the IP joints tend to tighten and shorten. This causes a flexion contracture, where the joints lose full extension and the fingers rest in a bent position. Edema and trauma amplify this by promoting adhesions and making the palmar structures (like the volar plates and flexor tendons) more prone to shortening. Over time, lack of movement allows collagen to realign in a shortened state, making the contracture more persistent. Clinically, this is the common consequence of prolonged immobilization after surgery or following edema/trauma, and it’s why rehabilitation emphasizes controlled extension, edema management, and early mobilization to preserve range of motion. Hyperextension, dislocation, or fracture are not typical chronic outcomes of immobilization in this context.
