Stress fracture of the ulnar diaphysis in a recreational golfer.

PURPOSE

To report a very rare presentation of a stress fracture in a golfer: a stress fracture of the ulnar diaphysis.

CASE SUMMARY

A 44-year-old woman had a 4-week history of a sore left wrist. She had been playing golf daily and had had no sudden trauma. Extensor tendinitis was suspected. Symptomatic treatment was given. Radiographs showed a spiculated periosteal reaction of the distal ulnar diaphysis with no signs of fracture or bone destruction. The suggestion of a malignant lesion was raised. Magnetic resonance imaging showed a healing ulnar fracture and edema of the interosseous membrane.

DISCUSSION

In golfers, stress fractures may be seen in ribs laterally and in tibias. We believe supination together with overuse of the hand flexor muscles caused the stress fracture presented, which has not previously been reported in golfers.

RELEVANCE

Physicians should be aware of the potential for ulnar stress fracture in golfers with wrist pain.
