The aim of this study was to determine the center-edge angle (CEA) values according to age, gender and side in healthy children between 5 and 14 years old in Turkey and to find out the angular limit values for mild and severe dysplasia.
The data pool that was gathered to investigate the frequency of hip dislocation in children between 6 months and 14 years old in Turkey was used. The data pool consists of pelvis and lower abdomen radiographs obtained for reasons other than hip dysplasia. Lower abdomen/pelvis radiographies of children between 5 and 14 years old were extracted from the data pool and were evaluated. Distribution of CEA values according to age, gender and side was examined. Measurements were performed by a single investigator on computer by using a standard method. Reliability of the measurements was tested by three different investigators on randomly selected films by using the standard method.
CEA values of 3192 hips of 1596 children, who had no hip pathology, were measured. Mean CEA value was found as 26.2°±5.5°. The mean CEA was 26.2°±5.3° in males (%54) and 26.2°±5.7° in females (%46) (p=0.224). Mean values for the right and left hips were 25.7°±5.4° and 26.6°±5.6°, respectively. CEA value of 449 (14%) hips of 333 (20.8%) children was at the limit of mild dysplasia and CEA value of 70 (2.2%) hips of 58 (3.6%) children was at the limit of severe dysplasia. CEA values had increased by age and mild and severe dysplasia limits were determined for every age group.
The mild and severe dysplasia values that are defined according to ages in Turkish population will guide the investigators in the diagnosis, follow-up and treatment planning of developmental dysplasia.

本研究旨在确定土耳其5至14岁健康儿童的中心边缘角（CEA）值与年龄、性别及左右侧的关系，并找出轻度和重度发育异常的角度限值。
使用为调查土耳其6个月至14岁儿童髋关节脱位发生率而收集的数据库。该数据库包含因髋关节发育异常以外的原因获得的骨盆和下腹部X光片。从数据库中提取5至14岁儿童的下腹部/骨盆X光片并进行评估。检查CEA值按年龄、性别和左右侧的分布情况。由一名研究人员使用标准方法在计算机上进行测量。通过三名不同研究人员使用标准方法对随机选择的X光片进行测量，检验测量的可靠性。
测量了1596名无髋关节病变儿童的3192个髋关节的CEA值。平均CEA值为26.2°±5.5°。男性（占54%）的平均CEA为26.2°±5.3°，女性（占46%）为26.2°±5.7°（p = 0.224）。左右髋关节的平均值分别为25.7°±5.4°和26.6°±5.6°。333名（占20.8%）儿童的449个（占14%）髋关节的CEA值处于轻度发育异常的限值，58名（占3.6%）儿童的70个（占2.2%）髋关节的CEA值处于重度发育异常的限值。CEA值随年龄增加，且为每个年龄组确定了轻度和重度发育异常的限值。
根据土耳其人群年龄定义的轻度和重度发育异常值将为研究人员在发育性髋关节发育异常的诊断、随访和治疗规划方面提供指导。
IV级，诊断性研究。
