How do the shoulder and hip joint differ?

A good way to note difference is by thinking of the shoulder as more of a golf ball sitting on a golf tee and the hip as a true ball in socket. After looking at the anatomy above, you can see the shoulder joint is made up of the head of the humerus, which rests on the glenoid fossa of the scapula (or shoulder blade).

Which has more range of motion the hip or the shoulder?

The hip carries the weight of the body and thus requires strength and stability during standing and walking. For these reasons, its range of motion is more limited than at the shoulder joint.

What joints move during shoulder abduction?

The major movements at the glenohumeral joint are: Abduction: upward lateral movement of humerus out to the side, away from the body, in the plane of the scapula. Adduction: downward movement of humerus medially toward the body from abduction, in the plane of the scapula.

Can the shoulder joint abduction?

Overview. The human shoulder is the most mobile joint in the body. This mobility provides the upper extremity with tremendous range of motion such as adduction, abduction, flexion, extension, internal rotation, external rotation, and 360° circumduction in the sagittal plane.

When comparing the shoulder and hip joints How are they similar?

Both are ball and socket joints. Both have a large outer group of muscles that are “powerful movers” with an inner group of “fine tuners” (we are familiar with the Rotator Cuff of the shoulder – the hip essentially has one too!) Both share similar injuries (due to their similar structures).

Why hip joint is more stable than shoulder joint?

The hip joint is extremely strong, due to its reinforcement by strong ligaments and musculature, providing a relatively stable joint. Unlike the weak articular capsule of the shoulder, the hip joint capsule is a substantial contributor to joint stability.

What type of joint is hip joint?

The hip joint is a ball-and-socket joint that allows motion and gives stability needed to bear body weight. The socket area (acetabulum) is inside the pelvis. The ball part of this joint is the top of the thighbone (femur). It joins with the acetabulum to form the hip joint.

What joint category does the hip belong to?

ball-and-socket synovial joint
Overview. The hip joint (see the image below) is a ball-and-socket synovial joint: the ball is the femoral head, and the socket is the acetabulum. The hip joint is the articulation of the pelvis with the femur, which connects the axial skeleton with the lower extremity.

What limits shoulder abduction?

The first rib in an inspiratory position or the first four dorsal vertebrae can limit the movement of abduction; as well as all the joints that form the thoracic outlet (clavicle-sternum, clavicle-scapula, rib-sternum, rib-vertebra).

Why are the shoulder and hip joints similar?

Which joint has the greatest stability?

The most stable joints are sutures. Sutures are synarthrodial joints which means that they are immovable.

What is hip abduction?

Hip abduction refers to the movement of the hip joint as the leg is moved away from the midline of the body. As the hip is composed of a ball and socket joint, a degree of rotation is also present during this motion. A group of muscles contribute to hip abduction; the most important of these is the gluteus medius.

What is the difference between adduction and abduction in the shoulder?

In contrast, adduction is the movement of the anatomical structures towards the midline. Therefore, in the shoulder, adduction lowers the arms towards the body. Thus, the main difference between abduction and adduction is the direction of the movement with respect to the midline of the body.

What is the difference between the shoulder and the hip?

The hip obviously is a “weight bearing joint” unlike the shoulder which introduces many differences. The shoulder is much more dependent on muscles connecting directly to the ball for movement and function, namely the rotator cuff, however, oddly enough, there are muscles of the hip that have been coined “the rotator cuff of the hip.”

What is an example of excessive bilateral hip abduction?

Side splits are an example of excessive bilateral hip abduction. To see how the hip joint moves during this action we first need to look at how the two bones interact. The hip joint is a paired ball and socket joint that connects the pelvis to the legs.
