Abstract

Objective: This study reviews the literature and shares clinical experiences, emphasizing its diagnostic relevance in children under 5 years of age.

Method: We examined 169 cases of Legg-Calvé-Perthes disease (LCPD) in patients in this age group. We analyzed medical records and images, observing variables such as age, gender, complaints, treatment, and outcomes.

Results: We studied 20 patients with Meyer's dysplasia, representing 1.4% of LCPD cases in children. The majority were boys (85%) with symptom onset at 38 months. Claudication (25%) and mild pain (40%) were the main complaints. Radiographic findings showed a smaller, granular, or asymmetric nucleus. The average follow-up was 6.4 years, with interventional treatment in 5 cases. Most showed complete reossification and centralization of the femoral head.

Conclusion: Meyer's dysplasia is a rare condition that affects the hip in children under 5 years of age, predominantly in boys. It usually does not require intensive treatment; clinical and radiological follow-up is sufficient. However, it is important to be aware of possible unfavorable progressions, requiring more aggressive treatment to prevent complications. Level of evidence III, Retrospective comparative study.

儿童髋关节疼痛鉴别诊断中的梅耶氏发育不良。

目的：回顾文献并分享临床经验：本研究回顾了相关文献并分享了临床经验，强调了该病对 5 岁以下儿童的诊断意义：我们对该年龄组的 169 例 Legg-Calvé-Perthes 病（LCPD）患者进行了研究。我们分析了病历和图像，观察了年龄、性别、主诉、治疗和结果等变量：我们研究了20名迈耶氏发育不良患者，占儿童LCPD病例的1.4%。大多数患者为男孩（85%），发病年龄为38个月。主要症状为跛行（25%）和轻微疼痛（40%）。放射学检查结果显示核较小，呈颗粒状或不对称。平均随访时间为 6.4 年，其中 5 例接受了介入治疗。大多数病例显示股骨头完全再化和集中：结论：迈耶氏发育不良是一种罕见的髋关节疾病，多发于5岁以下儿童，以男孩居多。通常不需要强化治疗，只需进行临床和放射学随访即可。但是，必须注意可能出现的不利进展，需要更积极的治疗以预防并发症。证据等级 III，回顾性比较研究。
