间断垂直不可吸收缝线联合尼斯结治疗髌骨下极骨折22例

  目的   探讨间断垂直不可吸收缝线联合尼斯结治疗髌骨下极骨折的技术要点及疗效。  方法   选取云南大学附属医院骨与创伤外科2016年01月至2020年12月收治髌骨下极骨折共22例行间断垂直不可吸收缝线联合尼斯结治疗患者（观察组），同时选取同期行克氏针钢丝张力带治疗的患者21例（对照组），阐述技术要点并根据各项指标综合评估临床疗效。  结果  （1）观察组手术时间、术中出血量、骨折愈合时间均明显短于对照组（P < 0.05）；（2）观察组膝关节活动度（术后1、3、6月）均大于对照组（P < 0.05）；观察组Lysholm评分（术后1、3、6、12月）、KSS评分（术后1、3、6月）均高于对照组（P < 0.05）；（3）观察组无1例出现膝前疼痛，而对照组有12例；随访终末期膝关节Bostman评分优良率（100%）观察组显著高于对照组（95.23%）。  结论   间断垂直不可吸收缝线联合尼斯结治疗髌骨下极骨折避免了金属材料的使用，软组织激惹少，操作简单易行、耗时短、出血量少、固定牢靠，术后功能恢复好，远期内置物无需二次手术取出，有极佳的临床应用价值。

Interrupted Vertical Non-Absorbable Sutures Combined with Nis Knots in the Treatment of Inferior Pole Patella Fractures

  Objective  To Explore the technical points and clinical efficacy of interrupted vertical non-absorbable sutures combined with nis knots in the treatment of inferior patellar pole fractures.   Methods  A total of 22 patients admitted to the Department of Bone and Trauma Surgery of the Affiliated Hospital of Yunnan University from January 2016 to December 2020 with intermittent vertical non-absorbable sutures combined with nice knot treatment for inferior pole patella fractures were selected as the observation group, while 21 patients who were treated with a wire tension band with a knot needle at the same time were selected as the control group, and the technical points were elaborated and the clinical efficacy was comprehensively evaluated according to the index of each group.   Results  （1）The operating time, intraoperative bleeding and fracture healing time in the observation group were significantly shorter than those in the control group（P < 0.05）. （2） Knee mobility（1, 3, and 6 months after the surgery） was greater in the observation group than that in the control group（P < 0.05）; Lysholm score（1, 3, 6, and 12 months after the surgery） and KSS score（1, 3, and 6 months after thesurgery） were higher in the observation group than those in the control group（P < 0.05）; （3） None of the cases in the observation group had anterior knee pain, while there were 12 cases in the control group; End-stage knee at follow-up Bostman score excellent rate（100%） was significantly higher in the observation group than that in the control group（95.23%）.   Conclusion  Intermittent vertical non-absorbable sutures in combination with nis knots for the treatment of inferior pole patella fractures can avoid the use of metallic materials, have the advantages of less soft tissue irritation, simple and easy operation, short time-consuming, less bleeding, firm fixation, good postoperative functional recovery. Therefore, there is no need for the secondary operation to remove the long-term implant and have the excellent clinical application value.
