Analysis of Difficulties and Complications Following Implantation of Modular Prostheses in Patients with Lower Limb Bone Tumours.

The implantation of a modular prosthesis is the most popular method of reconstruction of bone defects in oncological patients. Along with clear-cut benefits associated with this procedure, there is also an increased risk of complications. Common complications include deep infections, aseptic loosening and mechanical implant damage. This study assessed the risk of complications following the implantation of a resection prosthesis in patients with lower limb bone tumours and to evaluate difficulties encountered during the treatment. A total of 149 patients with lower limb tumours treated at the Department of Oncological Ortho-paedics in Brzozów had resection prostheses implanted in the years 2016 and 2017. We analysed this series and available literature reports with regard to complications of the procedure and those encountered during the treatment. The mean duration of the surgical procedure was 117±45 minutes. Intraoperative complications occurred in 18 cases. Gluteal muscle failure was seen in 34 (43%) of the 74 patients with proximal femoral tumours, and impaired knee extension was noted in 4 (67%) of the 6 patients following resection of the proximal tibia. There were two cases of dislocation following megaprosthetic reconstruction of the hip joint. Impaired wound healing was noted in 7 (5%) patients. Post-operative trophic lesions of the skin were seen in 2 (2%), and peripheral nerve damage in 2 (2%) patients (fibular nerve). Thromboembolic complications were noted in 3 (3%) patients. No aseptic complications, mechanical implant damage or deaths were recorded. 1. The most frequently encountered complication following the implantation of a modular prosthesis was muscle failure, which was associated with the extent of the procedure. 2. Aseptic loosening and mechanical implant damage were rare and occurred in the early postoperative period.
