Treatment of a patient with breast cancer with bone metastases remains a challenge for orthopaedic surgeons and oncologists. Problem is especially important since breast cancer is still the most common cancer in women and bone metastases are most common metastatic site. We present a case report where treatment of proximal femur metastasis five years after primary breast cancer diagnosis not onl...

Background. Multifocal osteosarcoma is usually described as the occurrence of the tumour at two or more sites in a patient without pulmonary metastases and may be synchronous or metachronous. Case report. A previously well 21-year old male, who presented with a swollen, painful right knee with no history of trauma, was found to have a high-grade osteosarcoma of the distal tibia and proximal fem...

In this case report, we show how it is possible to perform osteosynthesis using minimal invasive techniques instead of conventional methods. In this instance the osteosynthesis was performed on a patient in poor general condition who had presented a periprosthetic fracture of the proximal femur. For the osteosynthesis the Less invasive Stabilization System intended for distal femur fractures wa...

Type BI rotationplasty is currently indicated for children with tumours of the proximal femur whereas type BIIIa rotationplasty is reserved for those in which the entire femur has to be removed. Our aim was to compare these two types of rotationplasty and determine whether the knee should be preserved in children with tumours of the proximal femur. We compared the post-operative complications, ...

BACKGROUND Fibrous dysplasia of the proximal femur is a progressive, often recurrent condition of bone that can cause skeletal deformity, fractures, and pain [corrected]. Allogeneic cortical strut grafting to minimize the risk of fracture or as part of fracture treatment is a promising treatment option, but evidence is scarce on the intermediate- to long-term results of this procedure and there...

The forces exerted by the soft and hard tissues of the thigh together represent a system in equilibrium. This balance of loads must be considered when the system components are examined independently. However, in many biomechanical analyses of the thigh, the femur is studied without considering soft tissue loading. To improve the understanding of femoral loading a three-dimensional model was de...

INTRODUCTION Atypical insufficiency fractures of the femur in patients on long-term bisphosphonate therapy have been well described in recent literature. The majority of cases are associated with minimal or no trauma and occur in the subtrochanteric or diaphyseal region. CASE PRESENTATION We describe the case of a 76-year-old British Caucasian woman who presented initially to an emergency dep...

We investigated the effect of the Birmingham hip resurfacing (BHR) arthroplasty on the bone mineral density (BMD) of the femur. A comparative study was carried out on 26 hips in 25 patients. Group A consisted of 13 patients (13 hips) who had undergone resurfacing hip arthroplasty with the BHR system and group B of 12 patients (13 hips) who had had cementless total hip arthroplasty with a proxim...

BACKGROUND The present study contrasts the accuracy of different reconstructed models with distinctive segmentation methods performed by various experts. Seven research groups reconstructed nine 3D models of one human femur based on an acquired CT image using their own computational methods. As a reference model for accuracy assessment, a 3D surface scan of the human femur was created using an ...

We reviewed retrospectively the results in 211 consecutive patients who had undergone limb salvage for bone neoplasia with endoprosthetic reconstruction of the proximal femur (96), distal femur (78), proximal tibia (30) and total femur (7). Their mean age was 50 years (11 to 86) and the mean follow-up period was 37.3 months (1 to 204). A total of 35 (16.6%) prostheses failed. Overall, implant s...
