What this trial studies

This study evaluates the effectiveness of flexor tenotomy in preventing the recurrence of toe ulcers in diabetic patients with a history of toe ulceration. It aims to assess changes in interphalangeal and metatarsophalangeal joint angles, barefoot plantar pressure during walking, and quality of life before and after the intervention. The study is a mono-center, investigator-blinded, randomized controlled trial comparing flexor tenotomy to usual care, which includes orthoses and shoe offloading. Outcomes will be measured and compared between the intervention and control groups to determine the efficacy of the treatment.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the recurrence of toe ulcers in diabetic patients, potentially preventing amputations.

How similar studies have gone: While the specific approach of flexor tenotomy for ulcer prevention is being evaluated, similar interventions have shown promise in managing foot complications in diabetic patients.
