Tenosynovitis of the Extensor Carpi Ulnaris

SYMPTOMS

There is acute or gradual onset of exercise-induced pain and swelling over the ulnar aspect of the wrist. Tenosynovitis can affect any
tendon in any location.

AETIOLOGY

These symptoms are caused by tenosynovitis and/or subluxation of the extensor carpi ulnaris tendon. It is common in tennis players,
golf players, weightlifters and jockeys.

CLINICAL FINDINGS

There is localised tenderness on palpation and on the ulnar aspect of the dorsal part of the wrist.

INVESTIGATIONS

Ultrasound or MRI can verify the diagnosis.

TREATMENT

Addressing the cause of this injury is vital, to avoid a chronic problem. A soft wrist brace may be helpful.

REFERRALS

Refer to Dr Kevin Yip (+65 9724 1219) senior consultant orthopaedic surgeon if this diagnosis is suspected or if the diagnosis is not clear.

EXERCISE PRESCRIPTION

Most sports can be maintained during healing. Running, cycling and water exercises (when the wound is healed after surgery) are good alternatives to keep up general fitness. Gym training can be maintained.

EVALUATION OF TREATMENT OUTCOMES

Normal clinical symptoms and signs and good hand function. Compare with other hand.

DIFFERENTIAL DIAGNOSES

This is a clear clinical diagnosis but is often missed.

PROGNOSIS

Excellent, if treated appropriately.
