Approximately 96 percent of patients who undergo fusion foot surgery for calcaneus fractures have successful outcomes, states the National Center for Biotechnology Information. Surgeons achieved success in 83 of the 86 fusions studied, which included highly comminuted fractures. Workers' compensation patients who undergo the surgery typically experience less success.
The type of graft material used does not affect fusion success rates. However, patients who undergo local graft or freeze-dried cancellous allograft procedures spend significantly less time in the hospital than those who undergo autogenous iliac crest grafts, notes the National Center for Biotechnology Information.
A comminuted calcaneus fracture is one in which the calcaneus, or heel bone, shatters into multiple pieces. The fractures often occur in high-energy impacts such as motor vehicle collisions, notes the American Academy of Orthopaedic Surgeons.
