The femoral neck (also femur neck or neck of the femur) ... This article incorporates text in the public domain from page 243 of the 20th edition of Gray's Anatomy (1918)
The zona orbicularis and proximal hip joint capsule are poorly understood. Recent studies seem to confirm that the proximal to middle part of the articular capsule, including the zona orbicularis, acts biomechanically as a locking ring wrapped around the femoral neck and thus is a key structure for hip stability in distraction.
The head of the femur is connected to the shaft through the neck or collum. The neck is 4–5 cm. long and the diameter is smallest front to back and compressed at its middle. The collum forms an angle with the shaft in about 130 degrees. This angle is highly variant. In the infant it is about 150 degrees and in old age reduced to 120 degrees ...
the femoral region encompassing the thigh, the popliteal region encompassing the back of the knee, the sural region encompassing the back of the lower leg, the calcaneal region encompassing the heel, the plantar region encompassing the sole of the foot. Some regions are combined into larger regions.
If there is a fracture of the neck of the femur, the blood supply through the ligament becomes crucial. The head of the femur is relevant to orthopedic surgery because it can undergo avascular necrosis and consequent osteochondritis dissecans. The femoral head is removed in total hip replacement surgery.
The medial circumflex femoral artery (internal circumflex artery, [1] medial femoral circumflex artery) is an artery in the upper thigh [2] that arises from the profunda femoris artery. [1] It supplies arterial blood to several muscles in the region, as well as the femoral head and neck.
A femoral fracture that involves the femoral head, femoral neck or the shaft of the femur immediately below the lesser trochanter may be classified as a hip fracture, especially when associated with osteoporosis. Femur fractures can be managed in a pre-hospital setting with the use of a traction splint.
In human anatomy, the body of femur (or shaft of femur) is the almost cylindrical, ... it is continuous above with the lower border of the neck, below with the medial ...
