骨锚在慢性踝关节前外侧不稳手术中的临床应用

目的探讨和总结微型带线骨锚钉在治疗慢性踝关节前外侧不稳手术中的临床疗效和使用经验。方法选择2008年4月～2010年4月我院收治的慢性踝关节前外侧不稳患者38例。所有病例均采用强生Fastin RC带线锚钉手术解剖重建外踝韧带。本组男性25例,女性13例;年龄19～32岁,平均（24.1±6.4）岁。结果 38例均获得随访13～25个月,平均（16.8±6.7）个月,术后所有踝关节活动度基本恢复正常,均未出现复发性踝关节不稳。关节功能根据美国足踝骨科协会（AOFAS）足踝评分进行评估。术前与术后AOFAS后足评分有极显著性差异（P〈0.01）。结论运用微型带线骨锚钉解剖重建外踝韧带,有效恢复了踝关节外侧的稳定性,是治疗慢性踝关节前外侧不稳合理想有效的方法。

Clinical application of anchoring nail in treating chronic anterolateral ankle instability

Objective To discuss and summarize the clinical effect and experience of anchoring nail in treating chronic anterolateral ankle instability.Methods From Apr.2008 to Apr.2010,reconstruction was used for surgical treatment of chronic anterolateral ankle instability with anchoring nail in 38 patients.There were 25 males and 13 females,whose age ranged from 19 to 32 years old(average 24.1±6.4 years old).Results Totally 38 patients were followed up for 13-25 months,averaging 16.8±6.7 months.Functional stability was achieved and range of motion was generally recovered without recurrent instability.The therapeutic results were evaluated with grading scale developed by American Orthopaedic Foot and Ankle Society(AOFAS).There were obvious differences between two groups in AOFAS values before and after operation.Conclusion With reconstruction technique and anchoring nail,lateral instability of ankle can be stabilized effectively.It is a reasonable and effective surgical method for the treatment of chronic anterolateral ankle instability.
