腕关节镜监视经皮螺钉内固定治疗新鲜腕舟骨骨折的初步临床疗效研究

Scaphoid fracture treated by percutaneous fixation with arthroscope assistance

摘要:

目的  探讨关节镜监视经皮微创治疗腕舟骨骨折的临床疗效。方法  该科2009年10月-2015年5月收治12例腕舟骨骨折患者运用关节镜探查腕关节并在腕关节镜监视下复位腕舟骨经皮微创螺钉固定，如合并三角纤维软骨复合体（TFCC）损伤一期进行处理，术后12例患者均得到随访，并进行回顾性分析。术前常规行三维CT及MRI检查。12例患者均在伤后15d内进行手术治疗。结节部骨折8例，腰部骨折4例。年龄20～58岁，男7例，女5例，慢速车祸外伤6例，运动损伤4例，摔伤2例。应用改良Mayo腕关节评分标准及Herbert和Fisher腕舟骨骨折评价标准评价手术后随访结果，随访时间12～24个月，平均随访时间18.5个月，患者健侧为对照并进行统计学处理。结果  合并TFCC损伤2例，为中央型。对术后6和12个月行常规X线影像学检查，术后6个月全部骨折愈合。术后12个月腕关节评分标准患侧与健侧差异无统计学意义。结论  运用腕关节镜经皮固定腕舟骨骨折，具有复位精准，创伤小，不遗漏TFCC等损伤，康复较快等优点。

Abstract:

Objective To investigate the preliminary clinical results of treating scaphoid fracture by percutaneous fixation with arthroscope assistance. Methods From October 2009 to May 2015, a consecutive series of 12 patients with scaphoid fracture were treated by percutaneous fixation with arthroscope assistance. Meanwhile TFCC was managed if necessary. As followed, X-ray was adopted for assessment bone healing at 6-month postoperation, 12-month postoperation. Postoperative evaluations included clinical measurement (grip strength and motion range), radiographic, and functional (modified Mayo wrist score) parameters, Herbert and Fisher scaphoid fracture parameters. Healthy wrist as control group. Results All the scaphoid fracture were healed with an average healing time of 24 weeks. All 12 cases were followed for an average of 18.5 months. The function was rated excellent in 7 cases, good in 5 cases according to the modified Mayo wrist score. There was no difference between the injuried wrist and control group. Conclusion For scaphoid fracture, percutaneous fixation with arthroscope assistance is a reliable and minimally invasive method to treat scaphoid fracture.
