A 36-year-old male who plays squash regularly complains of
pain in his wrist that is aggravated by turning the wrist, grasping anything
or making a fist. The pain radiates towards his forearm.
On examination there is no obvious deformity of his hand.
There is swelling and tenderness in the dorsal compartment of his wrist. You
ask the patient to make a fist with his thumb held inside the fingers and then
you passively ulnar deviate his fist and this reproduces the pain. There are
no abnormalities of motor or sensory function of the hand.
In this patient the diagnosis is likely to be:
Arthritis of the first carpometacarpal joint
de Quervain’s tenosynovitis
Carpal tunnel syndrome
