Outcomes of Abductor Repair Using Mesh Augmentation in Oncologic Proximal Femur Replacement.
Curr Oncol
September 2024
Department of Orthopedic, Mayo Clinic, Rochester, MN 55905, USA.
Unlabelled: Reconstruction of the abductor mechanism remains a primary challenge with contemporary proximal femoral replacement (PFR) surgery. Previously, techniques such as trochanteric preservation or direct repair to the implant have been described; however, these strategies are limited in their ability to tension the repair and reattach other muscles of the hip girdle. The aim of this study was to evaluate the outcomes of patients undergoing oncologic PFR using a novel technique of mesh augmentation for soft tissue repair.

Background: There is conflicting data regarding the optimal abductor mechanism (AM) repair technique after resection of proximal femur tumors. We sought to compare functional outcomes following tumor resection and reconstruction with proximal femoral replacement based on the AM repair technique utilized.
Methods: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.
Techniques for abductor reattachment in proximal femoral replacement for non-oncological reconstructions: a narrative review.

Background And Objective: Proximal femoral replacement due to revision hip arthroplasty or catastrophic proximal femur fracture fixation failures with considerable proximal femur bone loss can lead to a substantial loss of function of the soft tissue around the hip and the abductor muscles in particular. Surgical techniques of gluteus medius repair and/or abductor mechanism reattachment/reconstruction are widely debated in the literature, but it is quite rarely dealt with in the context of megaprosthesis and femoral reconstruction, particularly in non-oncologic patients. The aim of this study is to present a narrative review of the literature on techniques for abductor reattachment in proximal femoral replacement for non-oncological reconstructions.

From the Department of Orthopedic Surgery, McGill University Health Centre, Montreal, Quebec, Canada.
Introduction: Resection of the proximal femur raises several challenges including restoration of the abductor mechanism. Few evaluated the outcomes of different techniques of abductor fixation to the proximal femur endoprosthesis.
Methods: A retrospective review of patients who underwent proximal femoral arthroplasty with a minimum follow-up of 12 months was conducted.
Proximal femoral replacement using the direct anterior approach to the hip.

Objective: Proximal femoral replacement (PFR) is a salvage procedure originally developed for reconstruction after resection of sarcomas and metastatic cancer. These techniques can also be adapted for the treatment of non-oncologic reconstruction for cases involving massive proximal bone loss. The direct anterior approach (DAA) is readily utilized for revision total hip arthroplasty (THA), but there have been few reports of its use for proximal femoral replacement.
