Regenerative Tissue Matrix as an Interpositional Spacer Following Excision of a Cuboid-Navicular Tarsal Coalition: A Case Study

This article describes the use of an acellular human dermal regenerative tissue matrix as an interpositional spacer to maintain the distance between the cuboid and navicular, and to prevent recurrence, following surgical excision of a cuboid-navicular tarsal coalition in an adult female. The use of this acellular matrix as an interpositional spacer has previously been documented for use in association with arthroplasty for the treatment of hallux rigidus. After more than 3 years of follow-up, the patient was progressing well and there was no evidence of recurrent coalition or consolidation of the resection site. To the best of our knowledge, this is the first report of the use of this material for the treatment of tarsal coalition, published in the peer-reviewed literature.
