Diagnostics
Assessment
Degloving Injury, Left Hand
Hand:
Fx, closed, complete, oblique,
displaced, 3rd metacarpal, L
Fx, closed, complete, transverse,
displaced, proximal phalanx, base of 5th, L
Musculature
• Extrinsic muscles
• Extrinsic extensor tendons cross the wrist and are
surrounded by tendon sheaths in six
compartments* bounded by the extensor
retinacular ligament.
• Extrinsic finger and thumb flexor tendons and the
median nerve enter the hand through the carpal
canal.
* Compartments and anatomy illustrated next
Musculature
• Intrinsic musculature includes thenar,
hypothenar, and interosseous muscles .
• Thenar muscles: abductor pollicis brevis, the
opponens pollicis, and the superficial head of the
flexor pollicis brevis.
• Hypothenar muscles: abductor digiti quinti, the
opponens digiti quinti, and the flexor digiti quinti.
• The dorsal interossei (4), commonly referred to as
dorsal intrinsics, abduct the fingers; the palmar
interossei (3)(palmar intrinsics) adduct the fingers.
ASSESSMENT
Radial Nerve Palsy
Median Nerve Palsy
•
Loss of palmar sensation along the volar
aspect of the thumb, index, long, and radial
border of the ring finger
•
Motor strength deficits include loss of
thumb opposition (APB), loss of thumb
interphalangeal (IP) joint flexion (FPL), and
loss of index distal interphalangeal joint
flexion (FDP).
Ulnar Nerve Palsy

Masse's sign.
Radial Nerve Palsy
• Extension posturing of the hand is important in
grasping and releasing functions.
• Most often caused by injuries following a spiral
fracture of the humerus
– The sharp bony ends of the fracture can impale the
radial nerve along its course.
• Loss of radial nerve function at this level results in
loss of wrist and finger extension (Wrist Drop)
Degloving Injuries
• Common with crush or shear mechanisms of injury
• Zone of internal injury is often greatly underestimated
by the external appearance of the limb.
– Skin and subcutaneous tissue are separated from the
underlying fascia in an open wound, or without break in
the skin.
• Degloved areas may lead to infected hematomas
• It is generally recommended that the degloving injury
be treated and healed before an incision is made in the
area to treat the fracture.
– Antibiotics and pain meds
