Correction of long term joint contractures of the hand by distraction. A case report

Joint contractures are a common complication of hand trauma. The conventional treatment consists of arthrolysis, tenolysis and occasionally arthrodesis. Frequently, this does not achieve a good result, particularly when there has been a long delay in presentation. Progressive lengthening of a joint by distraction (joint distraction) allows the release of joint contractures even in cases of failure of traditional methods. We present a case of a delayed (20 years) work related traumatic flexion deformity of the PIP joint of the left index and middle fingers. This was the result of a complete division of both flexor tendons of both fingers. The range of movements, both active and passive, was limited to 90/100° in the index finger and 95/100° in the middle finger. Following joint distraction using our lengthening device (Antão™, Portugal) the patient was able to achieve an active and passive range of movements of 10/100° for the PIP joint of the index finger and 40/100° of the middle. This clinical case shows the simplicity and application of our technique for the correction of joint contractures.
