[Medium-term Results after percutaneous Needle Fasciotomy in Dupuytren's Disease].

Background: Dupuytren's disease often leads to an increasing limitation in finger extension in affected patients. As the incidence rises with age, the number of cases is expected to rise in the future due to the demographic change. Therefore, an easy and patient-oriented treatment is required. In the following study, we investigated the short and medium-term results after percutaneous needle fasciotomy (PNF).

Patients and methods: Overall, 65 fingers of 40 patients were treated with PNF. We evaluated the total passive deficit of extension (TPED), the passive deficit of extension of the joints (PED), the Buck-Gramcko score, rate of recurrence, DASH score and patient satisfaction. The average age of the patients was 65,9 years. Most of the patients (82%) were male.

Results: Directly after the PNF, extension in the treated fingers improved significantly (TPED before PNF 74,6°±41,1 SD to 32,8°±29,0 SD after the procedure). By the time of the follow-up examination (30,2±13,9 SD months), TPED had increased again (52,7°±40,2 SD). The rate of recurrence was 29,7%, and a higher Tubiana stage before the procedure correlated significantly with a higher recurrence rate. Nevertheless, patients demonstrated a very high level of satisfaction with the procedure and almost all patients would choose to undergo PNF again.

Conclusion: Although it is associated with a relatively high recurrence rate, PNF represents an effective and patient-oriented treatment of Dupuytren's contracture.
