掌骨髁锁定钢板固定I区第五跖骨基底部骨折

Metacarpal condyle locking plate for fixation of zone I fracture of the fifth metatarsal

[目的]探讨掌骨髁锁定钢板治疗I区第五跖骨基底部骨折的临床效果。[方法]回顾性分析2017年6月—2020年6月采用掌骨髁锁定钢板治疗的第五跖骨基底部骨折19例患者的临床资料。评价临床及影像结果。[结果]所有患者均顺利完成手术,手术时间(51.6±9.7)min、切口长度(3.7±0.8)cm、术中失血量(15.5±2.4)ml。患者随访时间平均(10.9±2.8)个月,恢复完全负重活动时间(10.2±2.4)周。与术前相比,术后6个月及末次随访时VAS评分[(2.5±1.2),(1.7±1.2),(1.0±0.6),P<0.05]显著减少,AOFAS中足功能评分[(74.2±7.8),(83.2±8.3),(92.1±8.5),P<0.05]显著增加。19例患者中,骨折复位质量优16例,良3例。所有患者6个月内骨折均愈合。[结论]掌骨髁锁定钢板固定I区第五跖骨基底部骨折牢固稳定,临床效果满意。

[Objective]To evaluate the clinical outcomes of metacarpal condylar locking plate for fixation of zone I.fracture of the fifth metatarsal.[Methods]A retrospective study was done on 19 patients who received metacarpal condylar locking plate for fixation of zone I.fracture of the fifth metatarsal from June 2017 to June 2020.The clinical and imaging consequences were evaluated.[Results]All patients had operation performed smoothly with the operation time of(51.6±9.7)min,incision length of(3.7±0.8)cm,and intraoperative blood loss of(15.5±2.4)ml.The patients were followed up for(10.9±2.8)months on a mean,and resumed full weight-bearing activities in(10.2±2.4)weeks.Compared with those preoperatively,the VAS score at 6 months after surgery and the last follow-up significantly decreased[(2.5±1.2),(1.7±1.2),(1.0±0.6),P<0.05],while the AOFAS score significantly increased[(74.2±7.8),(83.2±8.3),(92.1±8.5),P<0.05].Among the 19 patients,the quality of fracture reduction was excellent in 16 cases and good in 3 cases,and all patients got fractures healed in 6 months.[Conclusion]Metacarpal condylar locking plate used for fixation of zone I fracture of the fifth metatarsal base is stable and achieves satisfactory clinical outcome.
