In 2012 collagenase Clostridium histolyticum (Xiapex) was approved by the SMC for restricted use for the treatment of Dupuytren's contracture. Xiapex was approved on a case by case basis for patients with a palpable pretendinous cord, giving rise to MCPJ contracture of greater than 30 degrees. As of September 2012 we began to offer Xiapex injections to patients in Ayrshire who enquired about the injection, and met the SMC criteria.

To date injections have been performed on 3 patients, in a total of 7 digits. Patients were assessed prior to injection and manipulation, with the degree of contracture recorded and DASH scores noted. Each patient then underwent a standard injection of 0.58 mg of Xiapex. 48 hours post injection each patient underwent manipulation under local anaesthetic, with contractures remeasured, pain scored using a visual analogue scale and complications noted. Each patient was then reviewed at 4 weeks post injection where the residual degree of contracture was recorded and a further DASH score completed.

Mean contracture at the MCPJ prior to injection was 57° (range 34–80), and mean DASH score of 20.8 (range 16.7–24.2). Following manipulation mean residual contracture at the MCPJ measured 21° (range 18–28). The average pain score following was manipulation was rated at 1.1. Mild bruising and swelling were reported in all cases following injection, and manipulation resulted in 2 minor skin tears. At the 4 week review prolonged improvement of contracture was achieved with a mean residual contracture of 14° (range −2–40); with a significant improvement in DASH scores – mean 0.6 (range 0–1.8)

Despite small numbers, we have found Xiapex injections to be a successful and well tolerated treatment for moderate Dupuytren's disease. Further follow up is required to assess the longevity of the correction and ensure the cost effectiveness of Xiapex.
