Transmetatarsal Amputation (TMA) Revision for a Non-Healing DFU | Marian Footcare Podcast | Ep. 5

In Episode 5 of the Marian Footcare Podcast, Dr. Imaze Marian Davis presents a complex limb salvage case involving revision of a prior transmetatarsal amputation (TMA) to address a diabetic foot ulcer (DFU) that failed to heal.Dr. Davis begins by reviewing the patient’s history, including the initial amputation performed elsewhere and the factors that contributed to delayed healing. She discusses the challenges commonly seen in post-amputation patients—such as pressure redistribution, soft tissue compromise, infection risk, and biomechanical imbalance.The episode then focuses on the decision-making process behind performing a TMA revision, with emphasis on achieving a more functional, stable, and durable residual limb. Dr. Davis explains the surgical approach, key considerations for wound closure, and strategies aimed at promoting healing while reducing the risk of further complications.This case highlights the importance of thoughtful surgical planning in limb salvage and the critical role podiatry plays in managing complex diabetic foot conditions. It offers valuable insight for both patients and clinicians into how advanced interventions can help close chronic wounds and preserve mobility.
