The femoral neck (also femur neck or neck of the femur) is a flattened pyramidal process of bone, connecting the femoral head with the femoral shaft, and forming with the latter a wide angle opening medialward.

2023年9月11日 · The femoral neck is about 5 cm long and can be subdivided into three regions. The most lateral aspect (the part closest to the greater trochanter) is known as the base of the femoral neck or the basicervical portion of the neck is the widest part of the neck of the femur.

2023年11月17日 · The femoral nerve supplies branches to the hip and knee joints. The femoral nerve innervates the quadriceps femoris (rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis), sartorius, and pectineus.

2020年11月13日 · Neck – connects the head of the femur with the shaft. It is cylindrical, projecting in a superior and medial direction. It is set at an angle of approximately 135 degrees to the shaft. This angle of projection allows for an increased range of movement at the hip joint.

2024年6月9日 · The femoral neck is a connecting bone structure between the femoral head and shaft. It is shaped like a flattened pyramid, with a wider angle outward. The neck is flat from front to back, narrower in the middle, and wider on the outer side compared to the inner side.

The neck of femur (femoral neck) is the short, constricted, bar-like part of the bone that connects the head and body of femur. It projects superomedially from the proximal end of the body of femur, with its lateral end being the widest, and its middle part being the narrowest.

2010年5月20日 · In an attempt to determine the position and course of the horizontal trabecular column within the femoral neck a series of femoral necks were dissected using a physical method. Unexpectedly, the findings of the study show that the internal structure of the femoral neck, overall, is more complex than has been previously described.

The neck of femur serves as the connecting link between the femoral head and the shaft. It is positioned at an angle of 125 degrees with respect to the shaft, allowing for smooth hip movements. The neck is characterized by two borders, namely superior and inferior, which meet the greater and lesser trochanters of the shaft, respectively.

The femoral neck axis was produced by drawing a straight line that by visual inspection was equidistant from the anterior/posterior or superior/inferior borders of the femoral neck along the neck’s length.

4 天之前 · Just distal from the head, the femur narrows considerably to form the neck of the femur. The neck of the femur extends laterally and distally from the head to provide extra room for the leg to move at the hip joint, but the thinness of the neck provides a …

2021年3月29日 · The neck of the femur connects the femoral head to the femoral body (shaft) and is surrounded by the joint capsule of the hip. View fullsize Femur Bone Anatomy: Neck of the femur (purple) connects the femoral head (green) to the femoral body/shaft (discussed below).

2024年12月26日 · The femoral neck is the constricted part of the femur connecting the femoral head to the shaft. Understanding its anatomy is crucial for orthopedic professionals. However, unrelatedly, the effects of THC on the body are also of interest; one might wonder, for instance, if is thc a depressant , which could impact bone health indirectly.

2025年1月28日 · The femur is a typical long bone, consisting of a head, neck, shaft, and distal end. Its robust structure allows it to withstand significant forces during activities such as walking, running, and jumping.

2016年5月22日 · The femoral neck is oval in shape. The orientation of the greatest diameter of the femoral neck relative to the mechanical long axis of the femur is defined with the angle ρ (rho).

- Femoral Neck Angle: - neck extends inferolaterally from head to meet shaft of femur at angle of about 125 deg; - angle varies w/ age, stature, & width of pelvis, being less in adult, in persons with short limbs, and in women;

Relevant Anatomy. The femoral neck and head articulate the axial force of weight from the shaft of the femur into the axis of the pelvis. With its angle and compression, the femoral neck is a uniquely vulnerable point focusing at Ward’s triangle, where femoral neck fractures most commonly occur.

2021年11月8日 · The femoral head narrows considerably to form the cylindrical neck that connects the head with its next region, the shaft. The neck is about 5 cm long and can be subdivided into three regions: Subcapital: Narrower than the basicervical, but wider than the midcervical part.

During hip replacement surgery, your surgeon removes the upper part of your thigh bone, including the femoral head (ball of the hip joint) and a part of the femoral neck (upper part of the thigh bone). This allows your surgeon to access the hip joint and perform the surgery.

Anatomy. Angle of 125° with shaft in adulthood; angle less in shorter femurs and wider pelvises (sa female). Points up, in and forward (12 – 14°). Big load-bearing and torsion associated with locomotion, are withstood by relatively small neck bone mass, through its tension and compression trabeculae and strong calcar femorale. Clinical

2025年1月22日 · Femoral neck fractures are common injuries to the proximal femur associated with increased risk of avascular necrosis, and high levels of patient morbidity and mortality. Diagnosis is generally made radiographically with orthogonal radiographs of the hip.

2023年11月13日 · The rectus femoris is the anterior thigh compartment's most superficial and nearly vertically oriented muscle. This bipennate structure is a component of the quadriceps muscle complex, one of the knee's most important dynamic stabilizers.[1] The rectus femoris is also known as the "kicking muscle" for its involvement in activities involving forceful knee …

1 天前 · The neck does so many things, all at the same time. For example, it transports over 2,000 pounds (907 kilograms) of blood, air and food between the head and the torso every single day.
