MEYER’S DYSPLASIA IN THE DIFFERENTIAL DIAGNOSIS OF HIP PAIN IN CHILDHOOD

Abstract

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.
