ORTHOSPHERE(®) interpostitional arthroplasty used in great toe interphalangeal joint arthritis-a case report

We report the first case in which an ORTHOSPHERE(®) spherical ceramic interposition arthroplasty has been used successfully in a patient with complex great toe pathology. The ORTHOSPHERE(®) (Wright Medical Technology, Arlington, TN) is a spherical ceramic interpositional arthroplasty designed for use in CMC joint arthritis. It has also been documented for use in basal fourth and fifth metatarsal arthritis [Shawen SB, Anderson RB, Cohen BE, Hammit MD. Spherical ceramic interpositional arthroplasty for basal fourth and fifth metatarsal arthritis. Foot Ankle Int 2007;28(8):896-901].
