hand wrist trauma management

✋ Hand & Wrist Trauma Management Hand and wrist trauma is common and can involve bones, joints, tendons, ligaments, nerves, blood vessels, and skin. Due to the complexity and functional importance of the hand, prompt and precise treatment is essential to restore full function and prevent long-term disability. 🚨 Types of Hand & Wrist Trauma 🦴 Bone Injuries Fractures: Distal radius: Most common wrist fracture. Scaphoid: High risk of nonunion due to poor blood supply. Metacarpals & phalanges: Can cause rotational deformities if not aligned. Dislocations: Often involve PIP joints, carpometacarpal joints (especially thumb). Crush Injuries: May involve multiple structures—bone, soft tissue, and nerves. 🧵 Tendon Injuries Extensor tendons: More superficial, easily lacerated. Mallet finger, Boutonnière deformity if not treated properly. Flexor tendons: More complex due to multiple pulleys in the fingers. Require precise surgical repair and structured rehab. 🧠 Nerve Injuries Often accompany lacerations or crush injuries. Median, ulnar, and radial nerves commonly involved. Symptoms: Weakness, numbness, paresthesia. Early microsurgical repair or grafting if needed. 🩸 Vascular Injuries Involve digital arteries or radial/ulnar arteries. May cause ischemia or compromise replantation. Require microsurgical repair in severe cases. 🧬 Soft Tissue & Skin Loss Lacerations, degloving injuries, or burns. May need skin grafts, local flaps, or free tissue transfer for coverage. 🩺 Initial Assessment & Management Primary Survey (Trauma Protocols) Follow ATLS principles for polytrauma. Ensure life-threatening injuries are addressed first. Focused Hand Evaluation Inspect for deformity, wounds, swelling. Neurovascular status: Check sensation and capillary refill. Tendon testing: Active flexion/extension of joints. Imaging: X-rays (AP, lateral, oblique) CT or MRI for complex cases (e.g., scaphoid, ligamentous injuries) 🧰 Definitive Management 🔹 Fractures & Dislocations Closed reduction and splinting for simple injuries ORIF (Open Reduction Internal Fixation) for displaced or unstable fractures External fixation for complex or contaminated injuries 🔹 Tendon & Nerve Repair Timing is critical—early repair within 1–2 weeks preferred Microsurgical techniques for nerves and flexor tendons Tendon grafting or transfers for delayed repairs 🔹 Soft Tissue Coverage Use skin grafts, local flaps (e.g., thenar flap), or free flaps Vacuum-assisted closure (VAC) may help in wound management 🔹 Infection Control Debridement of open wounds Broad-spectrum antibiotics for contaminated or bite injuries Tetanus prophylaxis as needed 🧠 Rehabilitation & Recovery Early Hand Therapy Supervised by certified hand therapists (CHTs) Focus on range of motion, strengthening, and function Splinting: Static or dynamic splints based on injury Complications to Avoid Stiffness or contracture Malunion or nonunion Chronic pain (CRPS) Loss of fine motor skills 🧑‍⚕️ Specialist Involvement Hand surgeons (orthopedic or plastic) Occupational/physical therapists Reconstructive microsurgeons (for complex or avulsion injuries) 🧭 Key Goals of Trauma Management Restore form, function, and sensation Minimize pain, infection, and stiffness Return to daily activity, work, and recreation safely
