To investigate the effectiveness of three-needle and two-cable structure in the treatment of inferior patellar pole avulsion fractures.
A clinical data of 62 patients with inferior patellar pole avulsion fractures who were admitted between January 2023 and December 2023 and met the selection criteria was retrospectively analyzed. Among them, the fractures were fixed with three-needle and two-cable structure in 32 patients (observation group) and traditional steel wire tension band in 30 cases (control group). There was no significant difference in the baseline data of age, gender, side of the affected limb, cause of injury, and disease duration between the two groups ( >0.05). The operation time, fracture healing and healing time, patellar height (Insall-Salvati index), occurrence of complications, knee range of motion, and Böstman score at last follow-up were compared between the two groups.
The operation time of the observation group was significantly shorter than that of the control group ( <0.05). Patients in both groups were followed up 6-12 months (mean, 10.4 months). X-ray films re-examination showed that all fractures healed, and the fracture healing time was significantly shorter in observation group than in control group ( <0.05); no significant difference was found in Insall-Salvati index between the two groups ( >0.05). During follow-up, the complications occurred in 2 cases (6.25%) of observation group and in 9 cases (30.00%) of control group, and the difference in the incidences between the two groups was significant ( <0.05). At last follow-up, the range of motion and Böstman score of the knee joint in observation group were significantly superior to control group ( <0.05).
Compared with the traditional steel wire tension band fixation, the three-needle and two-cable structure fixation of the inferior patellar pole avulsion fractures is firm, which allows the knee joint to move early after operation and is conducive to the recovery of knee joint function.
探讨三枚克氏针联合双钢丝结构治疗髌骨下极撕脱骨折的疗效。
回顾性分析2023年1月至2023年12月收治的62例符合入选标准的髌骨下极撕脱骨折患者的临床资料。其中，32例患者采用三枚克氏针联合双钢丝结构固定骨折（观察组），30例采用传统钢丝张力带固定（对照组）。两组患者的年龄、性别、患侧肢体、受伤原因及病程等基线资料比较，差异无统计学意义（>0.05）。比较两组患者的手术时间、骨折愈合及愈合时间、髌骨高度（Insall-Salvati指数）、并发症发生情况、膝关节活动度及末次随访时的Böstman评分。
观察组手术时间明显短于对照组（<0.05）。两组患者均随访6～12个月（平均10.4个月）。X线片复查显示所有骨折均愈合，观察组骨折愈合时间明显短于对照组（<0.05）；两组Insall-Salvati指数比较，差异无统计学意义（>0.05）。随访期间，观察组2例（6.25%）发生并发症，对照组9例（30.00%）发生并发症，两组并发症发生率差异有统计学意义（<0.05）。末次随访时，观察组膝关节活动度及Böstman评分明显优于对照组（<0.05）。
与传统钢丝张力带固定相比，髌骨下极撕脱骨折采用三枚克氏针联合双钢丝结构固定牢固，术后可早期活动膝关节，有利于膝关节功能恢复。
