Dupuytren's Disease Percutaneous Needle Aponeurotomy: Does Grip Strength Improve Post Procedure?

Background/Objectives: Dupuytren's disease (DD) presents significant challenges in hand function due to the progressive contracture of the palmar fascia. This study evaluates the impact of Percutaneous Needle Aponeurotomy (PNA) on grip strength before and after intervention. Methods: A prospective pilot study included patients with DD over 18 years of age who underwent PNA. Grip strength was measured at baseline, six weeks, and three months post-procedure using a Jamar Dynamometer. The median time to return to work or normal activities was recorded. Results: The study included a total of 29 participants. There was a recorded difference in one kilogram of baseline grip strength between the treatment and non-treatment hands. Patients reported improved hand function and recorded an average increase of 5.8 kg in grip strength at the three-month follow-up. Improvements were demonstrated in active extension, averaging 26 degrees at the metacarpophalangeal joint and 27 degrees at the proximal interphalangeal joint. Nine minor skin tears occurred, and there was no recorded recurrence. Conclusions: This study adds to the literature, confirming PNA is a safe and effective intervention for DD, offering rapid recovery and functional improvement. A larger study of a longer duration will help to establish whether grip strength gains are maintained following PNA.
