[Endoprosthesis in patients with dysplastic coxarthrosis or in those who suffered Perthes' disease in childhood]

Area of Science:

• Orthopedic surgery
• Hip joint biomechanics
• Regenerative medicine

Context:

• Coxarthrosis secondary to Perthes's disease presents unique challenges in young adults.
• Hip joint endoprosthesis is a common treatment for advanced hip osteoarthritis.
• Evaluating outcomes in specific etiologies like Perthes's disease is crucial for personalized treatment.

Purpose:

• To assess the efficacy of non-cement VerSys hip joint endoprosthesis in patients aged 40-50 with coxarthrosis post-Perthes's disease.
• To analyze the impact of concurrent or staged osteotomy and greater trochanteric repositioning on surgical outcomes.

Summary:

• Forty-eight patients with coxarthrosis secondary to Perthes's disease underwent hip joint endoprosthesis using non-cement fixation (VerSys).
• Osteotomy and greater trochanteric repositioning were performed in 33% of cases, either simultaneously or 3-6 months prior to endoprosthesis implantation.
• This approach addresses the specific anatomical and biomechanical considerations in this patient cohort.

Impact:

• Provides insights into the long-term viability of non-cement hip implants in younger patients with post-Perthes coxarthrosis.
• Highlights surgical techniques that may optimize functional recovery and implant longevity.
• Contributes to the understanding of managing complex hip joint pathology in a specific demographic.
