This study evaluated the effect of percutaneous needle fasciotomy on primary Dupuytren's contracture in 149 patients (213 rays) admitted to our clinic in 2007. Ninety-two patients (130 rays) were followed up for 2 years to compare the change in total passive extension deficit and the passive extension deficit across the individual joint and to note side effects. No tendon rupture or damage to sensory nerves was observed and the rehabilitation period was short (mean, 0.6 days). We found a significant change (p < 0.001) in total passive extension deficit after 2 years, but the effect of the treatment was greater in Tubiana I and II stages and our best results were in correction of MCP joint contractures. Percutaneous needle fasciotomy is an alternative treatment for elderly patients with severe comorbidity or for those patients who do not want open surgery.
