To the best of our knowledge, only 3 cases, including the present case, have been reported with a three part broken pattern. However, this is the first case associated with a distal locking screw broken. We report the case of a 31-year-old patient who sustained an open femoral shaft fracture . The fracture was stabilized with a Kuntcher femoral nail. After 7 months of the initial surgery he pre...

Periprosthetic femoral fracture post-total knee arthroplasty can lead to malunion. This may lead to abnormal force transmission and accelerated wear of the prosthesis. Accurate femoral deformity correction depends on the combined correction of the mechanical axis alignment and the lateral distal femoral angle. Modern external fixation correction devices allow for simultaneous gradual correction...

BACKGROUND There is no accepted landmark for the mechanical axis of the femoral axis in sagittal plane in conventional total knee arthroplasty. METHODS As palpable anatomic landmarks of the femur, lateral epicondyle, and anterior margin of the greater trochanter were identified. The line connecting these two landmarks was defined as the "palpable sagittal axis". The mechanical axis of the fem...

Morphometrical data were measured in the resected femurs of seventy Chinese patients who underwent total knee arthroplasties. Two measured parameters, the anterior-posterior length of the lateral condyle and the total width of the distal condyle, were compared to the anterior-posterior length and the medial-lateral width of five femoral implants currently used in Taiwan. Three implants (Duracon...

The ROSA (Robotic Surgical Assistant) Knee system (Zimmer Biomet, Warsaw, IN) for total knee arthroplasty (TKA) can be considered as collaborative robotics, where the surgeon remains in charge of procedure and collaborates with a smart robotic tool, to perform surgery high accuracy reproducibility. aim was describe: (1) its concept surgical technique; (2) advantages potential limits; (3) early ...

Objective- To evaluate the biological compatibility of differentiated stem cells embedded in poly-vinyl-alcohol (PVA) scaffolds for repair of distal femoral cartilage defect.   Design- Experimental in vivo study. Animals- Twelve adult male New Zealand white rabbits were used which were divided into two groups (I, II) six rabbits each.   Procedures- Mesenchymal stem cells were isolated from h...

25 This study aimed to demonstrate the higher accuracy and reproducibility of quantitative 26 computed tomography (QCT) compared with dual-energy X-ray absorptiometry (DXA) as a gold 27 standard for measuring canine bone mineral density (BMD). Seven middle-aged beagle dogs 28 underwent lumbar vertebral and bilateral femoral DXA and QCT scans. BMD (mg/cm) was 29 measured at the vertebral body fr...

The effects of regional hypotension on femoral resistance artery reactivity and morphology were investigated in spontaneously hypertensive rats (SHR) and control Wistar-Kyoto (WKY) rats. A partially constricting ligature (0.4 mm i.d.) was placed around the left external iliac artery at 5 weeks, which resulted in significantly reduced femoral mean arterial pressures distal to the ligature at 12 ...

Revisions of fractured, uncemented and extensively porous-coated femoral stems are challenging. In this article, we report three cases of revision surgeries for broken, cementless, and extensively porous-coated femoral stems with Solution stems (DePuy, Warsaw, Indiana). In all cases, minimally invasive endofemoral revision was successfully performed without femoral osteotomy or cortical fenestr...

The distal end of the femur traditionally encompasses the lower third of this bone. This zone varies greatly in the literature, from the distal 7.6 cm to the distal 15 cm of the femur. This chapter deals only with fractures that involve the supracondylar (metaphyseal) or intercondylar (epiphyseal) areas of the distal end of the femur. Distal femoral fractures that are purely diaphyseal are disc...
