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 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 ...
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.
Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction. SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain. [ 8][ 9][ 2][ 12] When the joint is ...
A tibial plateau fracture is a break of the upper part of the tibia (shinbone) that involves the knee joint. [ 1] This could involve the medial, lateral, central, or bicondylar (medial and lateral). [ 3] Symptoms include pain, swelling, and a decreased ability to move the knee. [ 1] People are generally unable to walk. [ 2]
The hip joint is formed between the femur and acetabulum of the pelvis. Transient synovitis of hip (also called toxic synovitis; see below for more synonyms) is a self-limiting condition in which there is an inflammation of the inner lining (the synovium) of the capsule of the hip joint. The term irritable hip refers to the syndrome of acute ...
Patellofemoral pain syndrome. Diagram of the bones of the lower extremity. Rough distribution of areas affected by PFPS highlighted in red: patella and distal femur. Patellofemoral pain syndrome ( PFPS; not to be confused with jumper's knee) is knee pain as a result of problems between the kneecap and the femur. [ 4]
Medial knee injuries (those to the inside of the knee) are the most common type of knee injury. [ 1 ] The medial ligament complex of the knee consists of: [ 2 ] This complex is the major stabilizer of the medial knee. Injuries to the medial side of the knee are most commonly isolated to these ligaments. [ 1 ][ 3 ] A thorough understanding of ...
