Q

Discuss the hip joint with respect to the following; type of joint, stability vs mobility.

A

The hip joint is a ball and socket joint, with the rounded convex femoral head articulating with the acetabulum of the hip bone.

The joint consists of the femur, os coxae (hip bone), joint capsule and its corresponding ligaments, tendons and muscles.

Unlike the shoulder joint, the hip is a more stable joint, but it does sacrifice some range of motion, for this stability.

49
If a muscle is a flexor, what motion would stretch that muscle?
Extend the muscle. (the opposite action)
50
What is gluteus medius gait?
the individual shifts the trunk over the affected side during the stance phase. The right gluteus medius, or hip abductor is weak. It causes 2 things to happen. 1. body leans to the weaker right side, and the right side of the pelvis will drop when the right leg leaves the ground and begins the swing phase. This gait is also referred to as a trendelenburg gait.
51
What is the pelvic girdle composed of?
Sacrum Coccyx Hip Bone- Comprised of Ilium, ischium, pubis
52
What is the sacral iliac joint?
The SI joint is synovial joint, non axial, articulation between the sacrum and the ilium, and is a plane joint. Function- to transfer weight from the upper body through the vertebral body to the upper extremities.
53
What is the symphis pubis?
Located anteriorly, in the midline of the body, it joins the right and left pubic bones. There is a fibrocartilaginous disk between the pubic bones, and there is little movement, but more movement is present during childbirth.
54
What is the lumbosacral angle?
located superiorly, angle is determined by drawing 1 line parallel to the ground and the other line at the base of the sacrum. We use the superior part of the pelvis for the reference point. When the pelvis tilts forward, the lumbar lordosis increases. When the pelvis tilts back, the lumbar lordosis decreases.
55
What are the functions of the pelvic girdle?
it supports the weight of the upper part of the body through the spinal column, and passes that weight to the lower extremities. Receives forces when the foot comes into contact with the ground, and those forces are transmitted up through the spinal column. The pelvic girdle moves in all 3 planes, because of that our walking is a lot smoother. The pelvis supports and protects the bladder, uterus, and the prostate in men. The pelvis provides attachments for muscles and muscular floor. The pelvis makes up the bony portion of the birth canal in females.
56
What comprises the sacrum?
5 fused vertebrae, sits posteriorly, between the 2 hip bones, and makes up the posterior border of the pelvis. It makes up the posterior border of the pelvis. The top part of the sacrum will articulate with the 5th vertebra, it is concave anteriorly, and convex posteriorly.
57
What are landmarks of the sacrum?
Dorsal surface, pelvic surface, base, body, sacral promontory, superior articular process, ala wing, auricular surface, foramina, tail bone or coccyx
58
What comprises the Ilium?
inominate bone or oscoxe bone = hip bone, in the hip bone there are 3 bones fused together. The top part is the ilium, front lower part is the pubis, and back lower part is the ischium.
59
What are the bony landmarks of the Ilium?
Iliac crest, auricular surface, iliac tuberosity, Posterior Superior Iliac Spine, Posterior Inferior Iliac Spine, Greater Sciatic Notch, Iliac Fossa, Anterior Superior Iliac Spine, Anterior Inferior Iliac Spine
60
What comprises the ischium?
Hip bone is composed of the ilium and 2 components on the bottom. The ischium is the anterior and posterior portion of the hip bone.
61
What are the bony landmarks of the ischium?
Ischial tuberosity, ischial spine, lesser sciatic notch, ramus.
62
What comprises the pubis?
the anterior and inferior portion of the hip bone.
63
What are the bony landmarks of the pubis?
Superior Ramus, Actetabulum, Obturator Foramen.
64
What are the pelvic girdle motions?
movement occurs in all 3 planes. Anterior Pelvic tilt, posterior pelvic tilt, lateral pelvic tilt, and pelvic rotation.
65
What is an anterior pelvic tilt?
Pelvis tilts forward, superior surface of pelvis as reference point. There is a muscular forced couple of the posterior trunk muscles, and anterior hip muscles.
66
What is a posterior pelvic tilt?
pelvis tilts backward, superior surface of pelvis as reference. The lumbar lordosis decreases with a posterior pelvic tilt. This also is a forced couple between the anterior trunk flexors (abdominal muscles) and the posterior hip extensors (gluteus maximus)
67
What is a lateral pelvic tilt?
when the 2 iliac crest are not level. If one side moves up, the other side moves down. During walking the pelvis is level when both feet are in contact with the ground. When 1 foot leaves the ground, the pelvis will drop on that side. Muscular force couple of erector spinii muscles, quadratus labrum, and your gluteus medius on the other side.
68
What is pelvic rotation?
occurs in a transverse plane, around a vertical axis. It happens when right side of the pelvis goes forward and left side goes back and visa versa.
69
Hip flexion
movement of the femur anteriorly toward the pelvis Normal ROM: 0-120* sagittal plane motion
70
hip extension
Movement of the femur straight posteriorly away from the pelvis Normal ROM: 0-15* sagittal plane motion
71
hip abduction
Movement of the femur laterally to the side away from midline normal ROM: 0-45* Frontal plane motion
72
hip adduction
movement of the femur medially towards the midline normal ROM: 0-25* frontal plane motion
73
When you sit down what are you sitting on?
the ischial tuberosities
74
hip internal rotation "medial rotation"
rotary movement of the femur medially around its longitudinal axis toward the midline normal ROM: 0-45* Transverse plane motion
75
hip external rotation "lateral rotation"
Rotary movement of the femur laterally around its longitudinal axis away from the midline Normal ROM: 0-45* Transverse plane motion
