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.
Hip arthroscopy. Intraoperative fluoroscopic image during an arthroscopic resection of a cam lesion of the femur. The upper instrument is the arthroscope (viewing device), while the lower is the high-speed burr used for reshaping the bone. Hip arthroscopy refers to the viewing of the interior of the acetabulofemoral (hip) joint through an ...
Frequency. ~15% of women at some point [ 1] 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.
D019644. MedlinePlus. 002975. [ edit on Wikidata] Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. [ 1] Hip replacement surgery can be performed as a total replacement or a hemi/semi (half) replacement.
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.
Femoral neck. Upper extremity of right femur viewed from behind and above. Right femur. Anterior surface. The femoral neck ( 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.
The third type of FAI is a combination of the first two deformities. When either abnormality is present, it changes the position that the femoral head occupies in the hip socket. The increased stresses that the femur and or acetabulum experience may lead to a fracture of the acetabular rim or a detachment of the overstressed labrum.
Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct. [citation needed] It is the most commonly used implant for extracapsular fractures of the hip, [ 1] which are common ...
