Hemiarthroplasty augmented with bone graft for the failed hallux metatarsophalangeal Silastic® implant

Abstract Symptomatic failure of Silastic® implants at the hallux metatarsophalangeal joint can result in the challenging problem of instability which may be painful. There is often marked bone loss making reconstruction difficult. Arthrodesis sacrifices joint movement while excision arthroplasty shortens the ray and is less acceptable to active patients. We describe a case in which reconstruction was achieved by using a porous coated metatarsophalangeal hemiarthroplasty augmented with bone graft with good early results. This previously unreported technique may offer an additional surgical option for reconstruction, maintaining joint movement without compromising future arthrodesis or excision arthroplasty as salvage measures. Long term follow up is required to confirm the success of this technique.
