Osteochondral allograft reconstruction of talar body fracture with a large bone defect.

ABSTRACT

Talar body fractures are rare and associated with a high rate of morbidity due to poor vascularity and the frequent occurrence of posttraumatic osteoarthritis. If talar body fractures are combined with a large bone defect, the situation becomes even more challenging due to difficult joint reconstruction. Only few reports have described the use of whole-bone fresh-frozen allografts for the treatment of foot trauma. Osteochondral bulk allografts can be used as an alternative to tibiotalar arthrodesis for the treatment of talar body fractures with large bone defects, especially in young patients. Here, we report a case of a talar body fracture associated with a large talar bone defect involving the posterior process that was treated by fresh-frozen osteochondral allograft for tibiotalar reconstruction in foot injuries.
