- Ligament sprains of the wrist usually result from falls on an outstretched hand.
- Most are mild and resolve with splinting and symptomatic treatment.
- Physical examination typically reveals no gross deformities, although dorsal swelling may be noted
Plain radiographs should be obtained in all patients with suspected
scapholunate sprain and should include
- a standard AP view
- AP with a clenched fist (accentuates scapholunate joint widening)
- standard lateral view
- posteroanterior (PA) view in ulnar deviation (assesses scaphoid bone for fracture).
- Simple scapholunate sprain require protection and rest with a period of splinting. After initial treatment, the patient is weaned from the wrist splint and begins active ROM and hand strengthening therapy.
