目的探讨带血管蒂髂骨瓣复合骨基质明胶移植治疗青壮年股骨颈骨折不愈合的疗效。方法本组28例股骨颈骨折经手术或非手术治疗6～9个月,骨折仍不愈合者,采用带血管蒂髂骨瓣复合骨基质明胶移植,术后观察骨折愈合,股骨头坏死及关节功能恢复情况。结果28例骨折全部愈合,关节功能按Ja-cobs标准评定,优19例,良7例,差2例。结论青壮年股骨颈骨折不愈合的手术治疗,带血管蒂髂骨瓣复合骨基质明胶(BMG)移植是有效术式,治疗结果体现了该术式具有“活骨移植”及诱导成骨的双重作用,疗效明显。

Objective To investigate the therapeutic effect of vascular pedicle bone graft and compound bone matrical gelatin (Co BMG) in treatment of nonunion of femoral neck fracture . Methods 28 cases of femoral neck fracture who had been treated with operation and traction and observed for 6 to 9 months suffered from nonunion. The 28 cases of nonunion were treated by vascular pedicle bone graft and compound bone matrical gelatin. The progress of bone healing, complications such as necrosis of femoral head, and joint function were followed up after operation. Results All the 28 cases healed. The function of joint was evaluated according to Jacobs criteria. It was excellent in 19 cases, fine in 7 cases, and poor in 2 cases. Conclusion The vascular pedicle bone graft combined with BMG is the effective choice for treatment of nonunion of femoral neck fracture in adolescents and adults, because it has the double effects of bone grafting and bone induction.
