The trochanteric fossa of the femur is a depression located on the posterior aspect of the greater trochanter, just below the trochanteric crest. It serves as an attachment site for the obturator externus muscle, which plays a crucial role in hip lateral rotation and helps stabilize the hip joint during various movements. Embark on an…
The apex of the fibula, the most distal portion of the bone, is located at the lateral malleolus of the ankle joint. It forms the outer and slightly lower part of the ankle joint. The apex articulates with the talus, a bone in the ankle, and is connected to the tibia through the anterior tibiofibular…
** Closely Related Entities ** An image of the femur depicts closely related anatomical structures such as the hip joint, knee joint, and patella. Understanding these relationships aids in surgical procedures like hip replacement and knee arthroplasty. Additionally, imaging modalities like X-rays, CT scans, and MRIs provide detailed views of the femur, enabling diagnosis of…
The lesser trochanter, a prominence on the femur’s posterior surface, lies near the base of the greater trochanter. It serves as an insertion point for the iliopsoas and pectineus muscles, which contribute to hip flexion and adduction. The iliopectineal ligament connects the lesser trochanter to the pelvis, enhancing joint stability. The proximity to the hip…
The femur, the thigh bone, is an integral part of the posterior thigh anatomy. It houses the sciatic nerve and provides attachment points for the hamstrings. Fractures of the femur, specifically intertrochanteric, subtrochanteric, and femoral shaft fractures, can occur due to various factors. Additionally, the knee joint, located at the distal end of the femur,…
A femur bone cross section reveals a structure of cortical and trabecular bone encircled by the periosteum and lined with the endosteum. Microscopically, bone exhibits a complex organization of osteons, Haversian canals, lacunae, canaliculi, collagen fibers, and Sharpey’s fibers. It possesses mechanical properties like strength and stiffness, and is prone to fractures and osteoporosis. Clinical…
Traction pin femur is a medical device used to stabilize femur fractures. It is a thin, Kirschner wire inserted through the distal femur into the heel. The pin is attached to a traction bow, which is connected to weights to apply traction to the femur, reducing the fracture and providing stability. Traction pin femur is…
The intercondylar notch of the femur, located between the medial and lateral condyles, is a U-shaped depression that accommodates the cruciate ligaments, crucial for stabilizing the knee joint. The posterior cruciate ligament (PCL) attaches to the posterior aspect of the notch, preventing posterior displacement of the tibia, while the anterior cruciate ligament (ACL) originates from…
Femoral Amputation Disarticulation of the femur entails the surgical removal of the entire lower limb at the level of the hip joint, leaving the hip socket intact. This uncommon amputation is primarily performed for severe infections or trauma, and the resultant prosthesis consists of a hip disarticulation device designed to provide mobility and stability. Anatomy…
Femur, the longest bone in the body, connects the hip and knee joints. Tibia, the larger bone of the lower leg, articulates with the femur at the knee and the ankle bone at the talocrural joint. The femur has a round head, a long shaft, and condyles at the distal end that form the knee…
Introduction: The femur, or thigh bone, is the longest and strongest bone in the body. It articulates with the hip bone at the proximal end and the tibia and patella at the distal end, forming the knee joint. Femoral Structure: The shaft of the femur is composed of compact bone, while the ends have cancellous…
The femur stands out among bones due to its unique greater trochanter, a prominent bony projection at its proximal end. This landmark serves as an attachment site for muscles involved in hip movement. The greater trochanter’s presence distinguishes the femur from other bones, making it a key anatomical feature for identification. Discover the Secrets of…
