Abstract
OBJECTIVE: Elimination of plantarization of the tip of the toe and torsion of digit 1 (D1) or D5 using percutaneous tenotomy of the flexor hallucis longus (FHL) - or the flexor digitorum longus (FDL) muscle. INDICATIONS: Flexible, in some cases also fixated hyperflexion misalignment and torsion misalignment of the distal phalanx of the toe with plantarization of physiologically non-loaded bearing parts of the toes in patients with diabetic foot syndrome (neuropathy). CONTRAINDICATIONS: Critical limb ischemia. SURGICAL TECHNIQUE: Percutaneous tenotomy of the FHL or FDL tendons using the minimally invasive lancet technique without the use of a tourniquet while the tendon is flexed by causing hyperextension of the distal phalanx and simultaneous extension of the distal interphalangeal (DIP) or interphalangeal (IP) joints. POSTOPERATIVE MANAGEMENT: Immediate full weight-bearing mobilization in sufficiently wide protective footwear with customized cushioning or a diabetes-adapted foot bed, follow-up in initially frequent intervals (2-4 per week) in order to track the development of the transfer lesions. In the case of existing wounds, more frequent visits and relief of the wounds using a post-operative shoe are required. No thrombosis prevention with full weight-bearing is necessary. RESULTS: In 138 patients with diabetic foot syndrome with polyneuropathy, of which 90 were men (65.2 %) and 48 were women (34.8 %) with a median age of 65.1 years, a total of 291 toe operations with tenotomy of the FHL- or FDL-tendon were performed. Patients were either acutely affected by apical toe lesions (92.1 %) or showed an increased risk of ulcer formation (7.9 %). The median time to closing of the wound was 13 days. It was longer with higher Wagner stages. Of the surgically treated toes 3.1 % were affected by nosocomial infections. At the 1‑year follow-up 92.4 % of the patients did not show pathological results of the operated toe. Recurrence of the DFS occurred mostly during the first 6 months postoperatively. In the first year postoperatively 68.1 % of the patients remained in remission. Of the toes with Wagner grade 0, 93.7 % were free of local recurrence during the entire monitoring period and 72.2 % of the operated toes with Wagner grade 3. Within the first 1.5-8.5 months 13 % of the patients were affected by transfer lesions.
