title: Management of a failed metatarso-phalangeal joint fusion utilizing a hemicup prosthesis.
abstract: We report a case of a 65-year-old man with a painful nonunion of the first metatarsophalangeal joint (MTPJ). It is one of the main severe complications of this surgery. Its prevalence is described between 5% and 10% across different operative techniques. The implantation of hemicup-prosthesis has been successfully used for the hallux rigidus treatment with very promising results. In our case report, we introduce a treatment method of converting a pseudoarthrosis of the first MTPJ, made of two crossing screws into a hemicup-prosthesis as a salvage procedure. This is to our best knowledge the first report using this device for treatment of pseudoarthrosis of the first MTPJ.
