Video Summary

The video presents a novel technique for tarsometatarsal joint fusion using calcaneal precision bone grafting. The study was carried out at the Freeman Hospital in Newcastle, UK. The traditional technique involves joint preparation using flat cuts and may or may not include bone graft. The precision technique involves using a locking plate that is contoured and provisionally fixed to the bone, followed by harvesting a cylinder bone block from the joint using precision grafting instruments. Bone graft is then harvested from the calcaneus and impacted back into the fusion site. Locking plates are fixed onto the bone to provide stable fixation. The precision technique offers benefits such as a greater fusion surface area, reduced graft site morbidity, and preservation of foot anatomy. In the study, 38 out of 39 joints reached fusion using this technique. It is concluded that fusion with locking plates and precision bone grafting is an appropriate treatment for tarsometatarsal joint arthritis, with improved outcomes compared to traditional bone graft techniques.
