Case 55 Degloving Injury
55.1 Description
Dorsal hand soft tissue defect secondary to avulsion mechanism
Dorsal: Zones V, VI, VII, and part of VIII
Full-thickness soft tissue defect down to extensor tendons
Paratenon has been stripped and extensor retinaculum is intact
Segmental loss of ring finger extensor tendon(s)
No vascular compromise distally
55.2 Work-Up
55.2.1 History
Age, gender, and social history, paying particular attention to handedness, occupation, smoking status, and substance abuse of the patient
Functional status of hand prior to injury
Previous injury or surgery of the hand in question
Manual demands of daily living and overall lifestyle
Past medical and surgical history
Timing and mechanism of injury
Trauma: Associated injuries, underlying fractures, dislocations, and neurovascular insult
Infection (if subacute or chronic)
Type of infection (bacterial, fungal, other)
Operative management to date (debridements, incision, and drainage)
Antimicrobial treatment and any resistance
Local versus systemic signs and symptoms
55.2.2 Physical Examination
Advanced Trauma Life Support (ATLS) protocol
Complete upper extremity examination starting with the shoulder, elbow, and hand
Brachial plexus injury is most common in motorcycle collisions
Location and size of soft tissue deficit
Specific deficits: Tendon, nerve, muscles, and skin
Wound bed status: Vascularity, exposed structures, and nonviable skin
Motor function: Delineate musculotendinous deficit from neurologic deficit
Sensory function
55.2.3 Pertinent Imaging or Diagnostic Studies
Plain radiography: Three views of hand, one joint above and below level of injury
Computed tomography (CT): In the setting of comminuted fractures requiring detailed evaluation
Angiography: Evaluate vascular patency for soft tissue transfer, when needed
