The Use of a Strut Allograft to Augment Internal Fixation of Nonunion Fractures in Osteoporotic Patients - a Report of Two Cases
內固定輔以結構性異位骨治療骨質疏鬆病患之骨折不癒合－兩病例報告
並列摘要
When treating fractures in patients with osteoporosis, internal fixation can be unreliable. Because the screw purchase over the osteoporotic cortex does not always assure rigid fixation, external support such as a cast is always necessary, and loss of reduction often occurs. Internal fixation with a plate is often tenuous because the osteoporotic bone cannot serve as a substrate for firm fixation of the screws. We report two cases in which strut allografts were used to augment the screw purchase and improve bony union. Follow-up of these patients showed that use of this technique led to bony union and good functional results. The strut allograft may achieve immediate stable internal fixation with the rigid screw purchase as well as stimulate fracture healing that permits early ambula-tion and weight-bearing. Thus, we recommend this technique as a good alterna-tive method in treating nonunion fractures in osteoporotic patients.
