The ligament of the head of the femur ( round ligament of the femur, foveal ligament, or Fillmore's ligament) is a weak [ 1] ligament located in the hip joint. It is triangular in shape and somewhat flattened. The ligament is implanted by its apex into the antero superior part of the fovea capitis femoris and its base is attached by two bands ...
Hip fracture. A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [ 2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [ 2] Usually the person cannot walk. [ 3]
A femoral fracture is a bone fracture that involves the femur. They are typically sustained in high-impact trauma, such as car crashes, due to the large amount of force needed to break the bone. Fractures of the diaphysis, or middle of the femur, are managed differently from those at the head, neck, and trochanter; those are conventionally ...
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
Degree of bulging of the femoral head-neck junction: In normal conditions there is a symmetric concave contour at the junction of the femoral head and neck. Loss of this concavity or bone bulging may lead to cam type impingement. The degree of this deformity can be measured by the alpha angle.
The femoral head's surface is smooth. It is coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the femoral head, and gives attachment to the ligament of head of femur . The thickest region of the articular cartilage is at the centre of the ...
As the lateral portion is twisted like a screw, the two parts together take the form of an inverted Y. [4] [verification needed] Arising from the anterior inferior iliac spine and the rim of the acetabulum, the iliofemoral ligament spreads obliquely downwards and laterally to the intertrochanteric line on the anterior side of the femoral head.
Elementary fracture Description Associated fractures Description Posterior wall: This is the most common variety of acetabular fracture. It typically occurs due to dashboard injury; when a person travelling in a vehicle involved in a head-on collision, the force applied over the flexed knee travels along the femur bone to the head of the femur, breaking the posterior wall of the acetabulum.
