Following a distal radius surgical repair, what area should the physical therapist prioritize addressing?

• A. Intrinsic muscle tightness
• B. Extrinsic extensor tightness
• C. Flexor carpi ulnaris tightness
• D. Shoulder joint tightness

Answer: (B)

After a distal radius surgical repair, the area a physical therapist should prioritize addressing is the extrinsic extensor tightness. This is primarily due to the anatomical considerations and functional requirements following a wrist injury.

Following a distal radius fracture, the wrist is immobilized during the healing process. Once the immobilization is removed, the extrinsic muscles responsible for wrist and finger extension, which originate from the forearm and cross the wrist joint, are often found to be tight and less flexible. This tightness can limit the range of motion and functional use of the wrist and hand.

Focusing rehabilitation efforts on this area allows for improved wrist extension, which is essential for a strong grip and effective use of the hand in everyday activities. Addressing tightness in the extrinsic extensors can also help prevent compensatory movement patterns that may arise due to stiff joints and limited motion, which could lead to additional issues in the long term.

While intrinsic muscle tightness, flexor carpi ulnaris tightness, and shoulder joint tightness may also be relevant in certain scenarios, they typically become secondary priorities once the functionality of the wrist extensors is restored. The primary goal post-surgery is to regain full range of motion and function at the wrist joint,
