“H”型拱桥式接骨板治疗股骨干骨折

Therapy of Femoral Shaft Fracture by H-type Arch bridge shaped Plate

目的 :探讨“H”型拱桥式接骨板治疗股骨干骨折的临床应用效果。方法 :随机选取 62例股骨干骨折患者 ,复位后均采用“H”型拱桥式接骨板固定。结果 :随访 5 9例 ,随访时间 4个月～ 3年 ,均达到骨折愈合 ,无并发症发生。结论 :该接骨板设计符合生物力学原理 ,有利于骨折的愈合 :其鞍状结构与管状骨固定时呈切线贴敷 ,可减少因压迫导致的骨坏死 ;钢板间的拱形连接和螺钉的交叉固定 ,可增强骨折断端的抗弯及抗旋转能力 ,其稳定性使患者术后早期即可进行功能锻炼 ,具有一定的临床应用价值。

Objective: To investigate the clinical effect of H type arch bridge shaped plate in treating the fracture of femoral shaft. Methods: Sixty two cases with femoral shaft fracture who were selected randomly were fixed by H type Arch bridge shaped plates after reduction. Results: Fifty nine healed completely during the follow up study of 4 months to 3 years, without complication. Conclusion: The design of the plate conforms to the principle of biomechanics and is good for the heal of the fracture: The saddle shaped structure made the plate and the cannular bone tangent when fixing so it can reduce the necrosis of the bone which is caused by pressure; The arch bridge shaped juncture and the mechanical bolts which are fixed across can strengthen the power of anti bending and anti rotation of the broken ends of the fractured bone. The stability of the fixation makes the patient do the functional exercise after the operation as soon as possible. It has definite clinical value and is worth of popularization.
