Abstract
Symptomatic failure of Silastic1 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.
