The purpose of this study was to retrospectively review the outcomes of percutaneous flexor tenotomies of diabetic claw toes with ulcers or pending ulcers.

A retrospective chart review between January 1999 and June 2005 was performed to identify those patients that had undergone a percutaneous flexor tenotomy for diabetic claw toe deformities. Thirty-four toes in fourteen patients were identified. Twenty-four toes had ulcerations at the terminal aspect and three of these had radiographic evidence of osteomyelitis of the terminal phalange. All patients had palpable pulses and good capillary refill. A percutaneous flexor tenotomy was performed in an outpatient clinic on all toes, patients with a rigid flexor contracture at the proximal interphalangeal (PIP) joint underwent an osteoclaysis to correct a portion of the deformity.

The average follow-up was thrirteen months, all patients with ulcers healed and there were no significant complications. Those without osteomyelitis healed within an average of three weeks and those with osteomyelitis healed within an average of eight weeks.

A Percutaneous flexor tenotomy with osteoclasis of the PIP joint performed in an outpatient clinic is a safe and effective method to off-load the tip of the toe such that ulcer healing can occur. The presence of osteomyelitis is not a contraindication for this technique; however, an increased healing time can be expected.
