Bones & Skeletal Tissue Flashcards
Kayla Tanner, a 45 year old mother of four, was a passenger on the bus involved in an accident on Route 91. When paramedics arrived on the scene, they found Mrs. Tanner lying on her side in the aisle. Upon examination, they found that her right thigh appeared shorter than her left thigh. They also notices that even slight hip movement caused considerable pain. Suspecting a hip dislocation, they stabilize and transported her. In the emergency department, doctors discovered a decreased ability to sense light touch in her right foot, and she was unable to move her toes or ankle. Dislocation of her right hip was confirmed by X-ray. Mrs Tanner was sedated to relax the muscles around the hip, and then doctors placed her in a supine position and performed a closed reduction (“popped’the femur back in place.)
.
Mrs Tanner’s pelvic girdle contains a hemispherical socket at the point where her femur attaches. Name this structure.
The hemispherical socket at the point where her femur attaches is called the acetabulum.
name the structure on the femur that forms the “ball”that fits into the “socket”you named in question 1.
The structure on the femur that forms the “ball” that fits into the “socket” named in question 1 is called the head femur.
There are three bones in the pelvic girdle that fuse together at a point within the structure that you named in question 1. Name those three bones.
The three bones in the pelvic girdle that fuse together at a point within the structure identified in question 1 are the ilium, ischium, and the pubis.
Mrs. Tanner suffered an injury to the hip joint, but if you were asked to rest your hands on your hips, you would not actually touch this joint. What structure in this pelvic girdle would your hands be resting on?
If you were asked to rest your hands on your hips, your hands would be resting on the iliac crests.
The sedation that Mrs Tanner was given was to relax the large muscles of the thigh and buttocks that attach to proximal end of the femur. name the structures on the femur where these muscles attach.
The structures on the femur where the large muscles of the buttocks and thigh are the greater trochanter and lesser trochanter.
Mrs Tanner’s injury caused damage to the sciatic nerve that passes across the hip and down into the thigh, lower leg, and foot. Name the pelvic structure that this nerve passes through as it travels into the upper thigh.
The structure of the pelvis that the sciatic never passes through as it travels into the upper thigh is the greater sciatic notch of the ilium.
