Isolated fifth digit localisation in Dupuytren's disease has a bad reputation. A series of this injury is reported with a special attention on recurrences. This series is composed of 30 cases in 26 patients (four bilateral cases): the majority of patients were male and 53.5 y was the average age. Extension loss of MP and PIP joints were present in 25 cases, MP isolated extension loss in two cases and PIP in three cases. The treatment performed was a percutaneous needle technique in five cases, surgical fasciectomy in 24 cases using a zigzag palmodigital longitudinal fasciectomy approach in 18 cases, an open palm technique in six cases and one isolated laterodigital flap. Assessment of correction was based on Tubiana's classification. Average follow-up was 22 months. Postoperative course was uneventful except for one case of precarious vascularisation which leads to an amputation. For the digitopalmar localisations: 15 stage 0 or 1, 7 stage 2, 1 stage 3 and 1 stage 4. Improvement percentage was 0.60 in combined cases, 0.65 in cases with a MP loss and 0.46 in PIP loss. Five recurrences were noted. Literature on this topic is coherent with the fact that isolated involvement of the fifth digit carry a bad prognosis, mainly due to the high recurrence rate in our series as in other papers. In severe injuries, an imperfect result should be the aim to prevent vasculonervous complications. |
