Avascular Necrosis of Hip, Hip Dysplasia, Legg-Calvâe-Perthes Disease
Conditions
Brief summary
This study, titled "Mixed-Methods Evaluation of Short-, Medium-, and Long-Term Outcomes Following Hip Treatment," aims to assess the long-term effectiveness of treatments for pediatric hip conditions, including hip dysplasia, Legg-Calve-Perthes disease, SCFE, and avascular necrosis.
Detailed description
Conducted at Mayo Clinic, the study combines retrospective chart reviews and prospective follow-up to gather data on clinical outcomes, radiographic measures, and patient-reported outcomes (PROs) like functional status, pain, and quality of life. The retrospective component analyzes records from 1975 to 2024, while the prospective component includes follow-up surveys using validated PRO measures (e.g., HOOS, SF-12, VAS). This study seeks to identify recurrence rates and complications associated with hip treatments, providing insights to improve future care standards for pediatric hip conditions. Data will be securely stored, with confidentiality maintained throughout.
Interventions
OTHERLong-term Follow-up Surveys
Patients will be given surveys, including validated PRO measures such as the Hip Disability and Osteoarthritis Outcomes Score (HOOS), Short-Form 12 (SF-12), Visual Analog Scale (VAS) for pain, and Marx activity scores.
