Which among these has least clinical implication on hip joint structure or function ?
a. Pulvinar
b. Quadrilateral plate
c. Sourcil
d. Teardrop
e. Cam bump
Answer -
e
Pulvinar is fibrofatty tissue over part of acetabulum fossa and quadrilateral plate bony part overlying the acetabular roof that makes for medial part of acetabulum; so both these are related to joint.
Sourcil is identified subchondral part of edge of acetabulum, sclerosis of which denotes stress and defective aetabular labrum thus indicates hip dysplasia.
Teardrop is radiological landmark made by projection of bony ridges running along floor of acetabular fossa and thus may have certain bearing on hip joint anatomy and function.
Cam lesion are structural deformity of head neck junction often with a bump seen radiologically and is responsible for femoro-actabular impingement (FAI). These have later bearing as precursor to hip arthritis but may be closest option here.
