Management of Painful Recurrent Intermetatarsal Neuroma Using Processed Porcine Extracellular Matrix Material: A Case Report.

Painful recurrent stump neuroma presents a common clinical problem following the transection of a nerve after initial interdigital neuroma excision but there is no gold standard of treatment. A patient presented with pain symptoms consistent with recurrent intermetatarsal stump neuroma after undergoing previous surgery to excise a Hauser neuroma. The recurrent stump neuroma was excised and the resulting nerve was capped and implantation into intrinsic muscle. Postoperatively, the patient experienced a complete resolution of pain and return of normal function. This article discusses capping material characteristics and considers the factors that may contribute to clinical success.
