➢ The failure rate of treatment of nonunions of the distal femur with internal fixation and autologous bone grafting remains high at 20% to 30%.➢ Successful treatment of nonunions of the distal femur requires good mechanical stability combined with autologous bone graft. This may require dual-plate fixation or intramedullary nail-plate combinations.➢ Autologous bone graft remains the bone graft of choice. Bone-graft substitutes and biologics require further research.

股骨远端延迟愈合或不愈合：综合概述。


➢ 内固定和自体骨移植治疗股骨远端骨不连的失败率仍然很高，为 20% 至 30%。成功治疗股骨远端骨不连需要良好的机械稳定性结合自体骨移植。这可能需要双板固定或髓内钉板组合。自体骨移植仍然是首选的骨移植物。骨移植替代品和生物制剂需要进一步研究。
