MEYER'S DYSPLASIA IN THE DIFFERENTIAL DIAGNOSIS OF HIP PAIN IN CHILDHOOD.

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.
