Clinical results of harvesting autogenous cancellous graft from the ipsilateral proximal tibia for use in foot and ankle surgery.

Abstract

The harvesting of autogenous cancellous bone graft has many uses in foot and ankle surgery. The most common referenced donor sites are the iliac crest, distal tibia, and calcaneus. These all have demonstrated limitations, the high morbidity rate associated with the iliac crest and the poor quantity of graft from distal sources. Between April 1995 and February 2000, 155 patients were retrospectively identified who had undergone a foot or ankle procedure utilizing the ipsilateral, proximal tibia as the donor site for autogenous cancellous graft. The patients were 18 years or older with no history of previous bony surgery to the tibia used and no history of previous injury or pain in the knee. The group included patients with isolated reconstructions as well as multiextremity trauma patients. All were kept nonweightbearing on the involved extremity for a minimum of 6 weeks postoperatively. There were 90 male and 65 female patients. The average age was 41 years and 5 months. There were 51 smokers averaging 17.6 pack years (range, 1-50 pack years). Twenty-six patients were admitted alcoholics, and 12 admitted to prior intravenous drug use. Cancellous graft was utilized in both traumatic and reconstructive settings. Eighty-nine fractures in 86 patients received grafting. Sixty-nine reconstructions or fusions of the hindfoot or midfoot were done using this technique. There were no reported major complications due to this procedure. No fractures, infections, or wound breakdowns occurred during this study. There were no reported long-term problems with knee pain or function. There was one postoperative hematoma that resolved over time. There were three incidents of sensory changes at the incision site. The use of the ipsilateral proximal tibia as a source for autogenous cancellous bone graft is a procedure with low added morbidity and a source of adequate graft material.
