Early Results of Acellular Dermal Matrix as an Interpositional Allograft Following Excision Arthroplasty of a Rheumatoid Forefoot: A Case Report.

This case report describes the use of a human acellular dermal matrix (ADM) as an interpositional allograft to stabilise and maintain the lesser metatarsophalangeal joint (MTPJ) pseudoarthrosis, and to prevent recurrent deformities, following arthrodesis of the first MTPJ and excision arthroplasty of the lesser metatarsals (MTs) for an elderly lady with severe rheumatoid forefoot deformities (RFDs). At six-month follow-up, the patient was recovering well with a clinically stable and radiographically well aligned foot, with no pain at the resection sites. She was also able to wear commercially available footwear.
