PURPOSE To evaluate the postoperative progress and outcomes of bone injured patients with long bone fracture showing callus formation and deformity due to delayed surgical treatment. MATERIALS AND METHODS 10 cases with more than 1 year follow up were chosen from 12 patients with long bone fracture whose surgical treatment was delayed due to brain injury. Exuberant callus formation and deformations were observed. Average delayed period was 6.7 weeks (4~10 weeks). Preoperative callus formation, shortening and angulation were evaluated using plain radiographs. Total operation time and transfusion amount were compared with that from operations done within 2 weeks following accident. Postoperative bone union was checked. RESULTS In all cases, preformed angulation and hypertrophic ossification made reduction difficult and this increased total operation time and transfusion amount but had no statistical importance. In patients with humerus and femur fractures accompanying brain injury, massive hypertrophic ossification was observed both in preoperative period and in postoperative period. Average bone union period was 13.5 weeks in humerus fractures, 17.9 weeks in femur fractures. The bone union period was shorter in subject group but had no statistical importance. CONCLUSION Early surgical treatment is essential to patients with long bone fracture accompanying brain injury but if early surgical treatment can not be done, proper immobilization to fracture site should be done.

PURPOSE The goal of our study was to evaluate the usefulness of frozen cancellous bone allograft in the treatment of long bone fractures that had bone defect and nonunion. MATERIALS AND METHODS 22 cases of long bone fractures(femur and tibia) with severe comminution or bone defect and nonunion were treated by operation using frozen cancellous bone allograft from March 1998 through May 2000. Thirteen were male and nine were female. The average age was 55 years old (range, 17-76 years) and the mean duration of follow-up was 20.1 months(range, 10-37 months). Eleven cases were femoral fractures, 7 cases of tibial fractures, and 4 cases of nonunion. Allografts were achieved from the patients of femoral neck fracture or osteoarthritis of the hip, and cadaveric donors. The specimens were carefully evaluated based on medical history and laboratory examination about the acute or chronic infection, and bloodtransmitted diseases. The results were evaluated by clinically, such as infection, pain at fracture site, immunological rejection and by radiologically union or resorption of allografts. RESULTS Radiologically, bone union was obtained in 14 cases(63.6%) at 6 months after operation, in all except two cases(90.9%) at 9 months after operation. Clinically, pain at fracture site, infection, and immunologic rejection were not observed. CONCLUSION In the treatment of severe comminuted fracture or nonunion of long bones, cancellous allograft transplantation after strict donor selection and appropriate screening was a good substitution for autograft avoiding of donor site morbidity or limitation in quantity.
