Forty-two cases of coxa vara were retrospectively reviewed. All 42 cases were classified based on their history and roentgenographic appearance. Twenty-two cases of true congenital coxa vara were identified and are the primary focus of this review. In this study we have introduced the Hilgenreiner epiphyseal (HE) angle as measured on standard AP roentgenograms of the hip. Retrospectively, this angle was measured to aid in deciding candidacy for surgery, as well as a means of determining the amount of surgical correction necessary to prevent a recurrence of the deformity. The indication for surgery should be an HE angle of greater than 60 degrees. HE angles of less than 60 degrees and greater than 45 degrees represent a "gray zone" and should be observed. HE angles of less than 45 degrees will generally correct spontaneously without surgery.
对42例髋内翻病例进行了回顾性研究。所有42例病例均根据其病史和X线表现进行分类。确定了22例真性先天性髋内翻病例，这是本研究的主要关注点。在本研究中，我们引入了在髋关节标准前后位X线片上测量的希尔根赖纳骨骺（HE）角。回顾性地测量该角度以帮助确定手术候选资格，以及确定预防畸形复发所需的手术矫正量。手术指征应为HE角大于60度。小于60度且大于45度的HE角代表“灰色区域”，应予以观察。小于45度的HE角通常会自发矫正而无需手术。
