Total hip arthroplasty with tantalum rod extraction via direct anterior approach based on preoperative DCE-MRI and AI: a case report

This case study highlights the importance of comprehensive preoperative assessment using DCE-MRI in guiding the selection of surgical interventions for ONFH. Specifically, DCE-MRI can identify patients who may not respond favorably to tantalum rod implantation due to inadequate blood supply in the necrotic areas. In such cases, alternative treatment options such as DAA-THA should be considered.
