hip joint(redirected from articulatio coxae)
Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.
the site of the junction or union of two or more bones of the body; its primary function is to provide motion and flexibility to the frame of the body. Some are immovable, such as the sutures where segments of bone are fused together in the skull. Others, such as those between the vertebrae, are gliding joints and have limited motion. However, most joints allow considerable motion. The most common type are the synovial joints, which have a complex internal structure, composed not only of ends of bones but also of ligaments, cartilage, the articular capsule, the synovial membrane, and sometimes bursae.
acromioclavicular joint the point at which the clavicle joins with the acromion.
ankle joint the joint between the foot and the leg; see ankle.
arthrodial joint gliding joint.
ball-and-socket joint a synovial joint in which the rounded or spheroidal surface of one bone (the “ball”) moves within a cup-shaped depression (the “socket”) on another bone, allowing greater freedom of movement than any other type of joint. See illustration. Called also polyaxial or spheroidal joint.
bicondylar joint a condylar joint with a meniscus between the articular surfaces, as in the temporomandibular joint.
cartilaginous joint a type of synarthrosis in which the bones are united by cartilage, providing slight flexible movement; the two types are synchondrosis and symphysis.
composite joint (compound joint) a type of synovial joint in which more than two bones are involved.
condylar joint (condyloid joint) one in which an ovoid head of one bone moves in an elliptical cavity of another, permitting all movements except axial rotation; this type is found at the wrist, connecting the radius and carpal bones, and at the base of the index finger. See illustration.
diarthrodial joint synovial joint.
ellipsoidal joint condylar joint.
facet j's the articulations of the vertebral column.
fibrous joint a joint in which the union of bony elements is by continuous intervening fibrous tissue, which makes little motion possible; the three types are suture, syndesmosis, and gomphosis. Called also immovable or synarthrodial joint and synarthrosis.
flail joint an unusually mobile joint, such as results when joint resection is done to relieve pain.
glenohumeral joint the synovial joint formed by the head of the humerus and the glenoid cavity of the scapula. Called also humeral joint and shoulder joint.
gliding joint a synovial joint in which the opposed surfaces are flat or only slightly curved, so that the bones slide against each other in a simple and limited way. The intervertebral joints are this type, and many of the small bones of the wrist and ankle also meet in gliding joints. Called also arthrodial joint and plane joint.
hinge joint a synovial joint that allows movement in only one plane, forward and backward. Examples are the elbow and the interphalangeal joints of the fingers. The jaw is primarily a hinge joint but it can also move somewhat from side to side. The knee and ankle joints are hinge joints that also allow some rotary movement. See illustration. Called also ginglymus.
hip joint the synovial joint formed at the head of the femur and the acetabulum of the hip. See illustration at hip.
humeral joint glenohumeral joint.
immovable joint fibrous j.
pivot joint a synovial joint in which one bone pivots within a bony or an osseoligamentous ring, allowing only rotary movement; an example is the joint between the first and second cervical vertebrae (the atlas and axis). See illustration. Called also rotary or trochoid joint.
plane joint gliding joint.
polyaxial joint ball-and-socket joint.
rotary joint pivot joint.
sacroiliac joint the joint between the sacrum and ilium in the lower back; see also sacroiliac joint.
saddle joint a synovial joint whose movement resembles that of a rider on horseback, who can shift in several directions at will; there is a saddle joint at the base of the thumb, so that the thumb is more flexible and complex than the other fingers but is also more difficult to treat if injured.
shoulder joint humeral joint.
simple joint a type of synovial joint in which only two bones are involved.
spheroidal joint ball-and-socket joint.
synarthrodial joint fibrous j.
synovial joint a specialized joint that permits more or less free movement, the union of the bony elements being surrounded by an articular capsule enclosing a cavity lined by synovial membrane. Called also articulation and diarthrosis. A capillary network in the synovial membrane provides nutrients and synovial fluid to nourish and lubricate the joint space. Strong fibrous bands or cords (ligaments) give strength and security to synovial joints. The majority of the body's joints are of this type. They are divided into five types according to structure and motion: ball and socket, gliding, saddle, hinge, and pivot.
trochoid joint pivot joint.
the ball-and-socket synovial joint between the head of the femur and the acetabulum.
The ball-and-socket joint formed by the head of the femur and the cup-shaped cavity of the hipbone.
See coxal articulation.
hip joint(hip joynt) [TA]
The ball-and-socket synovial joint between the head of the femur and the acetabulum.
Synonym(s): coxa (2) .
Synonym(s): coxa (2) .
hip jointa 'ball-and-socket' joint, where the globular head of the femur articulates with the cup-like hollow (the acetabulum) in the hip bone, which is deepened by a fibrocartilaginous rim; the joint is strongly supported by ligaments attached to this rim and the hip bone above, and to the femur where the neck joins the shaft. hip injury is important in sport as the initial treatment usually requires non-weight-bearing activity only and then often a prolonged rehabilitation. acute injuries can be the result of a fall, direct trauma or twisting; they include fractures, dislocations and soft tissue injuries to muscles and supporting ligaments. overuse injuriesresult from repetitive weight-bearing activity, such as road running, and include bursitis and tendonitis. See also Figure 1, Figure 2.

1. the region of the body around the articulation of the femur and the pelvis.
2. loosely, the hip joint.
os coxae, which comprises the ilium, ischium and pubis. See also Table 10.
manifested by inability to bear full weight on the limb, excessive mobility of the limb, crepitus at the joint, and in some cases shortening of the limb.
hip dysplasia (HD)
is manifested (1) radiographically by a shallow acetabulum, a small, misshapen femoral head and sometimes osteophyes, and (2) clinically, by a lax joint, weak rump muscles with or without lameness. In dogs inheritance has a degree of influence on the occurrence of the disease. See also degenerative joint disease.

a metal clamplike device used to lift a downer cow. Comprises two loops which fit over both iliac tuberosities (coxal tubers) and which are clamped together so that the cow is closely held. The sling is lifted with a block and tackle or by a frontend loader or hoist on a tractor.
total hip replacement
replacement of the femoral head and acetabulum with prostheses that are cemented into the bone; called also total hip arthroplasty.
the site of the junction or union of two or more bones of the body. See also arthritis. The primary functions of joints are to provide motion and flexibility to the skeletal frame, or to allow growth.
Some joints are immovable, such as certain fixed joints where segments of bone are fused together in the skull. Other joints, such as those between the vertebrae, have extremely limited motion. However, most joints allow considerable motion.
Many joints have a complex internal structure. They are composed not merely of ends of bones but also of ligaments, which are tough whitish fibers binding the bones together; cartilage, which is connective tissue, covering and cushioning the bone ends; the articular capsule, a fibrous tissue that encloses the ends of the bones; and the synovial membrane, which lines the capsule and secretes a lubricating fluid (synovia).
Joints are classified by variations in structure that make different kinds of movement possible. The movable joints are usually subdivided into hinge, pivot, gliding, ball-and-socket, condyloid and saddle joints.
For a complete named list of joints in the body see Table 11.
a synovial joint in which the rounded or spheroidal surface of one bone ('ball') moves within a cup-shaped depression ('socket') on another bone, allowing greater freedom of movement than any other type of joint. Called also spheroidal joint.
permits movement around two axes.
one in which the bones are united by cartilage, providing either slight flexible movement or allowing growth; it includes symphyses and synchondroses.
one in which an ovoid head of one bone moves in an elliptical cavity of another, permitting all movements except axial rotation. Called also condylar joint.
degenerative joint disease
a disease of the joints of all species and all ages but reaching a particularly high prevalence in pen-fed young bulls in which it is characterized by the sudden onset of lameness in a hindlimb, with pain and crepitus in the hip joint and rapid wasting of the muscles of the croup and thigh. There is a family predisposition to this degenerative arthropathy; it is exacerbated by a diet high in phosphorus and low in calcium and dense in energy so that the bull has a high body weight and is growing fast. The onset is acute and often precipitated by fighting or mating. The disease may not develop until 3 or 4 years of age in bulls that are reared at pasture. Called also coxofemoral arthropathy. See also hip dysplasia.
circumference of the joint is an ellipse with the articular surfaces longer in one direction than the other.
includes arthritis, arthropathy, rickets.

see hinge joint (below).
a synovial joint in which the opposed surfaces are flat or only slightly curved, so that the bones slide against each other in a simple and limited way. The synovial intervertebral joints are gliding joints, and many of the small bones of the carpus and tarsus meet in gliding joints. Called also arthrodial joint and plane joint.
a synovial joint that allows movement in only one plane, through the presence of a pair of collateral ligaments that run on either side of the joint. Examples are the elbow and the interphalangeal joints of the digits. The jaw is primarily a hinge joint, but it can also move somewhat from side to side. The carpal and tarsal joints are hinge joints that also allow some rotary movement. Called also ginglymus.
the joint between the head of the femur and the acetabulum of the hip bone; loosely called hip.

Patient discussion about hip joint
Q. What is the treatment for "hip joint mice"? Thanks!
A. if you are young- it goes away by itself after 6-8 painful weeks...if you are older you might need a surgery to remove the particles. it the hip bone it can be complicated, so it's really up to your Dr. to decide what to do here.More discussions about hip joint
