摘要
目的 比较可吸收螺钉与金属螺钉内固定治疗胫骨髁间嵴骨折的优缺点。 方法 将 1996年～ 2 0 0 2年收治的 2 0 0例胫骨髁间嵴骨折分为 A组 12 0例 (可吸收螺钉内固定治疗 )和 B组 80例 (金属螺钉内固定治疗 ) ,并对两组的生物相容性、生物力学、骨折愈合及并发症等进行比较。 结果 两组的手术时间与复位情况无明显差异 ,而在生物相容性、生物力学、骨折愈合及关节功能恢复等方面 A组较 B组优越。 A组骨折平均愈合时间为 3个月 ,B组为 3.5个月。以关节曲屈度 >90度为关节功能良好标准 ,两组的关节功能良好率分别为 98.0 %和 95 .0 % ,二者差异有统计学意义(P<0 .0 1) ;创伤性关节炎发生率分别为 1.7%和 3.7%。 结论 可吸收螺钉是胫骨髁间嵴骨折较理想的内固定材料。
Objective To compare advantage and disadvantage of internal fixation method for tibia intercondylar eminence fracture between absorbable screw and metallic screw. Methods From 1996 to 2002, 200 patients with fracture of tibia intercondylar eminence were divided into group A (with absorbable screw, n=120) and group B (with metallic screw, n=80). And the biological compatibility, biomechanics, bone union and complications were compared between two groups.Results There were no obvious differences in operating time and circumstance of recovery position between two groups. Group A was obviously better than group B in biological compatibility, biomechanics, bone union, joint function recovery. The average healing time of group A was three months, that of group B was three and half months. The good rates of joint function in two groups were 98.0% and 95.0% respectively. The occurrence rates of wound arthritis were 1.7% and 3.7%. There was significant difference between them(P<0.01). Conclusion Absorbable screw is a more ideal material of internal fixation to treat tibia intercondylar eminence fracture.
