Abstract

PURPOSE
Toe ulcers have been implicated as a causative factor in diabetic foot amputation. The aim of this study was to evaluate the outcomes of percutaneous needle flexor tenotomies of diabetic claw toes with ulcers or pending ulcers.
MATERIALS AND METHODS
The authors undertook a retrospective chart review between January 2014 and June 2016 to identify those patients who underwent a percutaneous needle flexor tenotomy for diabetic claw toe deformities. We evaluated 54 toes in 42 patients. Twenty-four patients were female and the mean age at the time of operation was 57 years. The mean follow-up time was 11 months. Thirty-four patients (46 toes) had tip toe ulcers or pending ulcers and 8 patients (8 toes) had dorsal pending ulcers. All patients had palpable pulses and good capillary refill.
RESULTS
Forty-three of 46 tip toe ulcers (93.5%) healed without significant complications and 8 dorsal ulcers showed no specific changes within 5 weeks. There were no recurrent ulcers at final follow-up. Four patients developed transfer lesion of the adjacent toe and needed subsequent tenotomy.
CONCLUSION
Percutaneous needle tenotomy in an outpatient clinic was an effective and safe method for treating toe ulcers in neuropathic patients to offload the tip of the toe so that ulcer healing could occur.
