Needle fasciotomy for Dupuytren's contracture- a prospective cohort study of 58 fingers with a median follow-up of 6.5 years.

Needle fasciotomy (NF) is a minimally invasive treatment option for Dupuytren contractures, but long-term results have indicated a high recurrence rate. This prospective study was initiated to monitor the introduction of NF in a context where limited fasciectomy had been the only treatment option, and to investigate the long-term results. The inclusion criterion was a palpable cord with a Metacarpophalangeal (MCP) and/or Proximal interphalangeal (PIP) contracture in one or more fingers. Fifty-eight fingers in 42 patients (40 male and 2 female with a median age of 68 years) were treated by needle fasciotomy between November 2010 and March 2012, and were followed for a median of 6.5 years. The median total passive extension deficit (TPED) was 52° at baseline, but decreased significantly to 20° postoperatively. No severe adverse events such as nerve or tendon injuries were reported. At final-follow up of 48 fingers the median TPED was still significantly reduced to 23° for all fingers ( p  < 0.0001). Twenty-nine fingers retained full correction of the contracture, and in patients with recurrent contractures NF was preferred in 13 out of 17 patients. This study showed that needle fasciotomy is a safe procedure for Dupuytren's contracture, with excellent immediate reduction of the joint contracture and with a recurrence rate comparable to treatment by collagenase clostridium histolyticum (CCH).
