目的分析比较可分离髌骨爪联合张力带保护钢丝与克氏针钢丝张力带对小儿髌骨粉碎性骨折的疗效及术后并发症情况。方法我院行手术治疗的小儿髌骨粉碎性骨折病人68例,随机分为观察组和对照组,每组34例。观察组予以可分离髌骨爪联合钢丝张力带固定,对照组予以克氏针钢丝张力带固定,出院后随访2年,比较两组病人手术时间、切口长度、骨折愈合时间、膝关节功能恢复评分及并发症发生率。结果两组手术时间[(51.54±4.13)分钟和(52.09±3.82)分钟]、切口长度[(6.92±0.12)cm和(6.93±0.14)cm]比较差异无统计学意义(P>0.05),观察组骨折愈合时间为(9.04±1.05)周,对照组为(10.88±0.92)周,观察组膝关节功能恢复评分优良率为91.18%,对照组为70.59%,观察组并发症发生率为2.94%,于对照组为20.59%,两组比较差异有统计学意义(P<0.05)。结论可分离髌骨爪联合张力带保护钢丝内固定可减少小儿髌骨粉碎性骨折愈合时间,膝关节功能恢复好,且术后并发症发生率低。
Objective To analyze the curative effect and postoperative complications of patellar claw combined with tension band protection wire and Kirschner wire tension band in children with patella comminuted fracture. Methods 68 cases of pediatric patellar comminuted fracture in our hospital were randomly divided into observation group and control group with 34 cases in each group. The observation group was treated with detachable patellar claw and wire tension band fixation, the control group was fixed with Kirschner wire tension band, followed up for 2 years after discharge. The operation time, incision length, fracture healing time, knee joint function recovery scores Complication rate. Results There was no significant difference in the length of incision (6.92 ± 0.12 cm vs 6.93 ± 0.14 cm) between two groups (51.54 ± 4.13 minutes and 52.09 ± 3.82 minutes) The fracture healing time was (9.04 ± 1.05) weeks in the observation group and (10.88 ± 0.92) weeks in the control group. The excellent and good rate of functional recovery score was 91.18% in the observation group and 70.59% in the control group, and the complication rate in the observation group was 2.94 %, 20.59% in the control group, the difference between the two groups was statistically significant (P <0.05). Conclusion Separable patellar claw combined with tension band protection of internal fixation wire can reduce the healing time of patella comminuted fracture in children, knee function recovery is good, and the incidence of postoperative complications is low.
