Early post-operative results of percutaneous needle fasciotomy in 451 patients with Dupuytren disease.

Background: Percutaneous needle fasciotomy (PNF) is a minimally invasive treatment modality for Dupuytren disease (DD). In this study we analyzed the efficacy and complication-rate of PNF using a statistical method that takes the multi-level structure of data, regarding multiple measurements from the same patients, into account. Methods: The data of 470 treated rays from 451 patients with Dupuytren disease that underwent percutaneous needle fasciotomy (PNF) were analyzed retrospectively. We described the early postoperative results of PNF and we applied linear mixed models to compare mean correction of PED between joints and efficacy of primary versus secondary PNF. Results: Mean preoperative PED's at the metacarpophalangeal (MCP), proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints were 37[spacing ring above], 40[spacing ring above] and 31[spacing ring above] respectively. Mean preoperative TPED was 54[spacing ring above]. Results were excellent, with a mean TPED correction of 85%. PNF was most effective for MCP-joints and less effective for PIP and DIP-joints. Secondary PNF was as effective as primary PNF. Complications were rare and mostly minor. Conclusions: The results of this study confirm that PNF is an effective and safe treatment modality for patients with mild to moderate disease who prefer a minimally invasive procedure.
