title: Percutaneous release of abductor pollicis brevis muscle fibrosis in a bowler--a case report.
abstract: The authors reported a patient with abductor pollicis brevis muscle fibrosis of the right thumb, stemming from a bowling injury that had occurred 6 years previously. At that time in the acute stage, a Chinese bonesetter treated the injury using manipulation, massage and herbal drugs. Abduction contracture of the patient's right thumb developed. She began to experience chronic pain at dorsal side of her right thumb and discovered that she could not move her thumb into a retro position. When she came into our hospital, physical examination revealed an abduction contracture of patient's right thumb, the angle of separation was 60 degrees, and the angle of circumduction was fixed at 90 degrees. In addition, a fibrotic band was palpable in abductor pollicis brevis muscle. The patient responded well to percutaneous release and physical therapy. As far as we know, this is an unusual case, which has not been reported before.
