In this retrospective study, we aim to describe the outcome of surgery in this location and further analyze the ﬁndings based on the type of surgical reconstruction. Methods: 47 patients (48 fractures) who underwent surgery due to pathological fractures of the distal third of the femur, between 2000 and 2024, were included in the analysis. There were 29 prostheses and 19 osteosyntheses (10 plates, 9 nails) . Local complications, implant revision rate, functional outcome regarding pain and ambulatory capacity, and overall survival were analyzed depending on the typeof surgical treatment. Results: The complication pattern was different among implants used, with severe infections seen in prostheses (3/29 implants) and tumor recurrence in osteosynthesis (2/19 implants) . In cases of osteosynthesis, failures resulting in revision surgery were documented only in cases of plate reconstruction (none when nails were used), resulting in a marginally higher revision rate (p = 0.14) . Surgical treatment resulted in the restoration of the ambulatory capacity in 85% of patients, and pain levels were minor or moderate in 93%, without any signiﬁcant difference between the surgical methods. Prostheses were used in patients with better overall survival (p = 0.015) . Discussion: The patterns of local complications and their management differed between the different reconstruction techniques. Plate osteosynthesis had the highest risk for re-operation. The overall postoperative result was satisfactory, and functional outcomes were generally comparable. Patients with a good prognosis should be considered for reconstruction with a prosthesis when the bone quality does not allow nail osteosynthesis. Level of evidence: IV, retrospective study.  \nKey words: Bone metastasis, Pathological fracture, Distal femur, Prosthesis, Osteosynthesis.  \nIntroduction  \nIn the appendicular skeleton, the femur is the most common location of metastatic bone disease. Treatment of impending or completed pathological fractures of this major weight-bearing bone is generally surgical. Metastases in the distal part of the bone are far less frequent than in the proximal [1] . There are only two previous studies describing surgical treatment in this location, reporting on 29 [2] and 16 [3] patients respectively. Since the number of patients reported in the medical literature is low, there is a noticeable knowledge gap resulting in the absence of treatment recommendations [4] . In this location, a variety of implants can be used, and the associated complications, their severity, and management, as well as the functional outcome, are poorly described. This renders decision-making on the proper surgical strategy difﬁcult.  \n*Corresponding author: [panagiotis. tsagkozis@ki. se](panagiotis. tsagkozis@ki. se)  \nGenerally, reconstruction of metastatic skeletal defects relies on either osteosynthesis (OS) or endoprosthesis(EP) [5] . Each strategy has advantages and disadvantages, and there is no consensus among orthopedic surgeons regarding the most appropriate method to be used; treatment choices ","cbCaihXLx2C5qEwR","https://ap.wps.com/l/cbCaihXLx2C5qEwR","pdf",338231,"English","# Abstract\n## Introduction\n## Methods\n## Results\n## Discussion\n# Introduction\n# Materials and methods","[{\"question\":\"What was the purpose of the study for distal femur metastases?\",\"answer\":\"To describe surgical outcomes for distal femoral metastatic lesions and to analyze findings based on the surgical reconstruction type.\"},{\"question\":\"What patients and fractures were included?\",\"answer\":\"Forty-seven patients (48 fractures) undergoing surgery for pathological fractures of the distal third of the femur between 2000 and 2024.\"},{\"question\":\"How did complications differ between prostheses and osteosynthesis?\",\"answer\":\"Severe infections were reported with prostheses, while tumor recurrence was seen with osteosynthesis; plate reconstructions also showed failures requiring revision surgery, with nails associated with none in the study results.\"}]","Outcome of surgical treatment for metastatic bone disease of the distal femur - Observational single-center study of 47 patients | PDF",1790742755,15]
