Total Hip Arthroplasty in the Adolescent Population: A Case Series.

Abstract

Introduction: Total hip arthroplasty (THA) is well-studied in adults but is not in younger populations.

Case series: Five adolescent THA patients from one institution were identified. Surgical indications included trauma, avascular necrosis, developmental hip dysplasia, and Perthes disease. Patients experienced hip pain impacting activities of daily living. At the most recent follow-up, patients were pain-free, ambulated without an aid or limp, and had returned to desired activities. Constructs were cementless; bearing surfaces included ceramic-on-ceramic and ceramic-on-polyethylene. Approaches included direct anterior and posterior. Radiographs demonstrated osseointegration of all components at the most recent follow-up. There were no major complications (dislocation, component loosening requiring revision, or infection).

Conclusion: THA in adolescent patients demonstrated significant clinical improvement in pain, low complication rates, and good implant survivorship, with patients able to return to desired activities.
