A proximal femur replacement requires precise alignment of the distal stem in order to align the proximal body with the appropriate femoral anteversion. A trial prosthesis of appropriate length, and offset is constructed.
Total femoral replacement (TFR) is a salvage arthroplasty procedure used as an alternative to lower limb amputation. Since its initial description in the mid-20 th century, this procedure has been used in a variety of oncologic and non-oncologic indications.
Advances in surgical technique and prosthesis design have expanded the non-neoplastic indications for proximal femoral replacement (PFR) to include fracture nonunion, periprosthetic fracture, and severe bone loss in the setting of revision total hip arthroplasty (THA).
Proximal femoral replacement (PFR) is a well-established treatment for neoplasia of the proximal femur. The use of this surgical technique for non-neoplastic conditions has increased over the years.
Proximal femur replacement is a salvage limb-sparing surgery for nononcologic and oncologic indications that in the past used to be treated with a major amputation. The magnitude of complexity of revision reconstruction of the femur depends mainly on the quantity and quality of femoral bone.
Proximal femur reconstruction is performed for metaphyseal–diaphyseal lesions that extend below the lesser trochanter, cause extensive cortical destruction, and yet spare at least 3 cm of distal femoral diaphysis for secure fixation of the femoral stem (18).
Proximal femoral replacement, also known as “megaprosthesis”, is a well-established limb salvage procedure for reconstruction of bone defects after the oncological resections of malignant bone neoplasms and the encouraging outcomes have broadened the indications to the treatment of severe bone loss in non-oncologic conditions [10, 11].
To allow for a reattachment of the pelvic trochanteric musculature in the presence of a 10 cm long defect of the proximal femur, a proximal femoral replacement including a Goretex membrane was utilized.
Proximal femoral arthroplasty (PFA) has already been popularized for tumour surgeries. Our aim was to describe the outcome of using PFA in these demanding non-neoplastic cases. Methods. A retrospective review of 25 patients who underwent PFA for non-neoplastic indications between January 2009 and December 2015 was undertaken.
Proximal femoral replacement (PFR) is a technically demanding procedure commonly performed to restore extensive, oncological or non-oncological bone defects in a severely debilitated patient collective. Depending on different indications, a varying outcome has been reported.
