肱内翻的X线分型及临床诊断(附21例报告)

Radiological typing and clinical diagnosis of humeral varus.A report of 21 cases

报告了1978～1994年间收集的21例肱内翻畸形，男17例，女4例，，年龄1～18岁，平均11．5岁，双侧发病1例，单侧20例，共22肢．对比了中立位、外旋位和内放位摄片的结果，认为外旋位摄片为诊断肢内翻的最佳位置。观察发现头干角与骺线角的大小与患肢功能活动受限程度密切相关．建议从放射线学上将其分为2型3度，认为Ⅱ～Ⅲ度的肱内翻需手术矫正。

Twenty-one cases of humeral varus deformity collected from 1974 to 1994 are reported in the paper. All the cases included 17 males and 4 females; one bilateral attack and 20 unilateral attacks (22 limbs affected), and ranged from 1 to 18 and averaged 11-5 years in age. Through the comparison of the film-taking results of three postures: neutrality, extorsion and intorsion, it was suggested that the extorsion is the best for taking a film in diagnosing humeral varus. Through the observations, it was found that the limitation of the affected-limb function is closely related to the capitodiaphyseal and epiphyseal-line angles. It was suggested that the disease should be radiologically divided into two types and three grades, and grades Ⅱ and Ⅲ should be corrected by surgery.
