Abstract:

目的 探讨微型锁定钢板跨腕掌关节内固定治疗第 5 掌骨基底部粉碎性骨折的临床疗效。 方法 2015 年 7 月—2017 年 12 月,共收治 8 例第 5 掌骨基底部粉碎性骨折患者,其中男 7 例,女 1 例;年龄 19~45 岁,平均 32.5 岁。致伤原因:握拳时击打硬物致伤 2 例,摔伤 6 例。合并第 5 腕掌关节半脱位 2 例,脱位 1 例。受伤至手术时间 1~5 d,平均 3.5 d。经术前评估不超关节固定或短时间超关节固定不能维持骨折端稳定性,故均采用切开复位微型锁定钢板跨腕掌关节内固定。术后观察并发症发生情况及骨折愈合情况;末次随访时按照中华医学会手外科学分会推荐的小指总主动活动度(total active motion,TAM)评价方法评价手部功能。 结果 术后患者切口均Ⅰ期愈合,均未发生切口感染、皮缘坏死、肌腱或神经损伤等并发症。8 例患者均获随访,随访时间 6~18 个月,平均 12 个月。骨折均愈合,愈合时间 12~16 周,平均 13 周。术后 4 个月内患者均返回受伤前工作岗位。末次随访时按照中华医学会手外科学分会推荐的小指 TAM 评价方法评价手部功能,获优 7 例、良 1 例,优良率 100%。 结论 采用微型锁定钢板跨腕掌关节内固定治疗不超关节固定或短时间超关节固定不能维持骨折端稳定性的第 5 掌骨基底部粉碎性骨折疗效满意,是一种可供选择的手术治疗方案
