可吸收高分子聚合物治疗胫骨髁间前棘骨折

目的观察可吸收高分子聚合物治疗胫骨髁间前棘骨折的临床疗效。方法1998-07—2002—07，将54例胫骨髁间前棘骨折分为A组31例（可吸收螺钉内固定）和B组23例（可吸收缝线内固定），并对两组的手术时间和术后膝关节功能恢复的情况进行观察。结果54例患者均获得随访，随访时间6个月-7年，平均3年6个月，52例膝关节功能恢复正常，A组1例术后出现创伤性关节炎，B组1例出现膝关节不稳。X线片示骨折全部愈合。结论可吸收高分子聚合物治疗胫骨髁间前棘骨折可取得良好的临床疗效，患者无需二次手术，与金属内固定物相比具有明显的优势。

The treatment of avulsion fracture of tibial intercondylar eminence with absorbable macromolecular polymers

Objective To investigate the clinical effects in the treatment of avulsion fracture of tibial intercondylar eminence with absorbable macromolecular polymers. Methods From July 1998 to July 2008, fifty-four cases of avulsion fracture of tibial intercondylar eminence were divided into group A（31 cases, with absorbable screw） and group B（23 eases, with absorbable suture） ,the time for operation and function of the knee were observed. Resuits All patients were followed up for 6 months to 7 years with average of 42 months. Fifty-two cases gained normal range of motion. One case was agonized by post-traumatic osteoarthritis in group A, and one ease was instability of the knee in group B. X-ray demonstrated bone union was achieved in all the cases. Conclusion Compared with un- absorbable material, absorbable macromolecular polymers have more curative effect in the treatment of the fracture of tibial intercondylar eminence, the second operation maybe avoided.
