Management of severe forearm injuries

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Reconstructive Surgery

Background:

• Severely mutilating forearm injuries present complex reconstructive challenges.
• Effective management requires a systematic approach balancing potential function with prosthetic options.

Observation:

• Crush-avulsion injuries necessitate aggressive debridement of damaged soft tissue and bone.
• Nerve avulsion, elbow joint destruction, and extensive muscle/tendon damage are significant contraindications to repair.
• Vascular and skeletal stability are paramount before soft tissue reconstruction.

Findings:

• Meticulous vascular repair using magnification and reconstruction of original anatomy is essential.
• Ingenuity is required for connecting muscle units to tendons, followed by early active motion.
• Nerve repair strategies vary based on injury type: group fascicular suture for sharply divided, epineural approximation for crushed nerves.

Implications:

• Primary skin coverage via split grafts or local flaps, with secondary options like myocutaneous or free flaps.
• Careful dressing application and protective splinting are vital for monitoring and recovery.
• Integrated perioperative physical and occupational therapy, including early active range of motion exercises, optimizes functional outcomes.
