Hip dysplasia in Children’s Hospital Dr. Ovidio Aliaga Uria

Abstract

Objective: To describe the clinical, and epidemiological characteristics and treatment in children with developing hip dysplasia (DCD) in the trauma outpatient clinic of the children’s hospital.

Methods: descriptive, prospective case series study in patients with DCD. An interview was conducted with parents or guardians based on epidemiological data and clinical and office data were obtained from the medical history.

Results: The average age of diagnosis was 9.3 months, range 3-18 months, with 51.1% of cases concentrated in children under 6 months. 62.8% were women, 26.7% had a family history of DCD, 46.5% were born by cesarean section, 11.6% had a breech presentation, 19.7% were premature, and 8.1% had at least one associated congenital malformation in limbs lower. 62.8% reported having performed traditional adduction wrapping. DCD was unilateral in 52.3%, affecting the left side in 77.8%. 65.9% presented clinical signs of DCD. In the radiographic film, 65.1% presented ossification nuclei, 70.9% had discontinuous Shenton’s arch, and the average acetabular angle from 3 to 6 months was right 30° and left 30.97°. The Pavlik Harness was used as a treatment in 51.2%, 24.4% required surgery, and 24.4% other treatments.

Conclusions: The average age for diagnosis was late (9 months) probably because it was a referral hospital. As in other studies, the most important risk factors present were female gender, birth by cesarean section, family history, prematurity, and breech presentation. Notably, traditional forced adduction occurred in almost two-thirds of the children. The left side was the most affected and the most frequent treatment is the Pavlik harness, although surgery was used in a quarter of the cases because it is a referral hospital.
