背景和目的-髋臼前倾角（AA）与髋关节功能有关。大多数先前的研究是基于确定骨性髋臼前倾（OAA）的影像学检查。但儿童髋臼大部分由软骨组成，软骨髋臼前倾角代表髋臼的真实的前倾角。我们用MRI测量了不同年龄儿童的OAA和CAA，并比较了正常髋关节和发育性髋关节发育不良（DDH）儿童的发育模式。患者和方法-OAA和CAA进行了测量MRI横断面的髋关节在293例儿童正常髋关节（平均年龄8岁），并在196例儿童DDH（平均年龄34个月）。通过年龄横断面分析，确定了髋关节正常儿童OAA和CAA的发育模式。比较发育性髋关节脱位与正常髋关节的OAA和CAA的差异。结果：正常的OAA在出生后的前2年从平均8.7°（SD 3.2）增加到12°（3.0），并保持不变，直到9岁。从9岁到16岁，OAA显示出2°-3°的最小增加。正常CAA在出生后的前2年内从平均12°（3.1）迅速增加到15°（2.7），并保持在15°（SD 3.4），直到16岁。正常组和DDH组年龄匹配的平均OAA分别为11°（3.2）和15°（3.0）（p < 0.001）。正常和DDH患者年龄匹配的平均CAA分别为17°（4.2）和23°（4.5）（p < 0.001）。同样，单侧DDH未受累髋关节的OAA和CAA与正常髋关节相比也有显著性差异（p < 0.001）。解释-CAA在正常儿童出生时完全形成，并保持不变，直到成年，而OAA随着年龄的增长而增加。DDH儿童的OAA和CAA均过度前倾。在计划髋关节手术时，MRI评估对骨骼发育期的儿童非常重要。
Background and purpose — Acetabular anteversion (AA) is related to hip function. Most previous studies were based on radiographic investigations that determine osseous acetabular anteversion (OAA). But children’s acetabulum is mostly composed of cartilage; the cartilaginous acetabular anteversion (CAA) represents the real anteversion of the acetabulum. We measured OAA and CAA in children of various ages using MRI, and compared the developmental patterns between children with normal hips and those with developmental dysplasia of the hip (DDH). Patients and methods — The OAA and CAA were measured on MRI cross-sections of the hips in 293 children with normal hips (average age 8 years), and in 196 children with DDH (average age 34 months). Developmental patterns of OAA and CAA in children with normal hips were determined through age-based cross-sectional analysis. Differences in OAA and CAA between children with normal hips and those with DDH were compared. Results — Normal OAA increased from mean 8.7° (SD 3.2) to 12° (3.0) during the first 2 years of life and remained unchanged until 9 years of age. From 9 to 16 years, the OAA showed a minimal increase of 2°–3°. The normal CAA increased rapidly from a mean of 12° (3.1) to 15° (2.7) within the first 2 years of life, and remained constant at 15° (SD 3.4) until 16 years of age. The age-matched average OAA in the normal and DDH cases was 11° (3.2) and 15° (3.0), respectively (p < 0.001). The age-matched average CAA in normal and DDH cases was 17° (4.2) and 23° (4.5), respectively (p < 0.001). Similarly, there was a significant difference in OAA and CAA between the uninvolved hips in unilateral DDH and normal cases (p < 0.001). Interpretation — The CAA was fully formed at birth in normal children, and remained unchanged until adulthood, whereas the OAA increased with age. The OAA and CAA were both over-anteverted in DDH children. MRI evaluation is of importance in children during skeletal development when planning hip surgery.
