Which joint is stronger hip or shoulder

Tendons connect muscles to bones. Fluid-filled sacs, called bursas, between bones, ligaments, or other nearby structures. They help cushion the friction in a joint. Other joints may move a little, such as the vertebrae. Examples of mobile joints include the following:. Ball-and-socket joints.

Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements. The bursa in the shoulder is on and around the rotator cuff and can become inflamed as described above. The most common area of bursitis of the hip, however, is on the outside or boney point of the hip called the trochanter and becomes inflamed due to a number of reasons.

On rare occasions, this does not successfully treat the pain and the bursa of the hip can be removed with the arthroscope and the IT band can be released. The shoulder has four muscles that make up the rotator cuff. They are responsible for elevation and rotation of the shoulder.

Tearing of the rotator cuff is rare below the age of 40 unless trauma occurs. However, as we age, the rotator cuff becomes more degenerative and tears are more common. Studies have shown that up to 50 percent of people in their sixties have some degree of rotator cuff tearing.

Tears of these muscles, most commonly the gluteus medius, occur in older individuals and are much less common than rotator cuff tears in the shoulder. Both the shoulder and the hip develop arthritis over time in many individuals. Arthritis is the wearing down of the smooth cartilage lining on the ball and socket of both joints. The arthroscopic treatments are limited for both joints but could be effective for removal of loose bodies and relieving mechanical symptoms.

Advanced arthritis is best treated with replacement if conservative efforts are not effective. If you experience any of these symptoms, discuss your options with your orthopaedic surgeon, who can help you determine the best course of action to improve your quality of life. Skip to content.

Types of joints Freely moving joints Types of movement Structure of a joint Joint conditions Where to get help. Types of joints Joints are described by how much movement they allow.

The three broad classes of joints include: Immovable — the two or more bones are in close contact, but no movement can occur — for example, the bones of the skull. The joints of the skull are called sutures. Slightly movable — two or more bones are held together so tightly that only limited movement is permitted — for example, the vertebrae of the spine. Freely movable — most joints within the human body are this type. Motion is the purpose of the joint.

Freely moving joints The six types of freely movable joint include: Ball and socket joint — the rounded head of one bone sits within the cup of another, such as the hip joint or shoulder joint.

Movement in all directions is allowed. Saddle joint — this permits movement back and forth and from side to side, but does not allow rotation, such as the joint at the base of the thumb. Hinge joint — the two bones open and close in one direction only along one plane like a door, such as the knee and elbow joints.

Condyloid joint — this permits movement without rotation, such as in the jaw or finger joints. Pivot joint — one bone swivels around the ring formed by another bone, such as the joint between the first and second vertebrae in the neck. Gliding joint — or plane joint. Smooth surfaces slip over one another, allowing limited movement, such as the wrist joints.

Types of movement To achieve movement, the joint may: Slide one broad and flat surface across another — examples include the bones in the wrist or ankle. Increase or decrease the angle between the two bones — this only occurs in the long bones of the body arms and legs : for example, when the arm is bent or extended.

Allow a circular movement — this is how ball and socket joints work: for example, the shoulder.
