2020年8月22日 · Different grading schemes are described for plain radiographs of the hip: grade 0: normal; grade 1: possible joint space narrowing and subtle osteophytes; grade 2: definite joint space narrowing, defined osteophytes and some sclerosis, especially in the acetabular region

information is needed on the radiographic joint space (JS) of the normal hip, including its shape, its width at precise locations, and the influence of age, sex, and congenital morphology. These normal values are needed to set the limits of significant early radiographic alterations in patients with osteoarthritis (OA).

Objectives: To determine the range of normal radiographic joint space width (JSW) values and the shape of the normal hip, and the influence of age, sex, dysplasia, coxa profunda, and acetabular roof curve abnormalities on these values.

In osteoarthritis, the cartilage in the hip joint gradually wears away over time. As the cartilage wears away, it becomes frayed and rough, and the protective joint space between the bones decreases. This can result in bone rubbing on bone.

The hip joint space in standard anteroposterior images of 120 normal subjects was measured with the aid of a special transparent pattern. The normal value was slightly over 4 mm, scattered between 3 and 5 mm, except for elderly men in whom values of 6 mm or more may be normal.

Joint space width measured at the hip joint is the radiological distance between the subchondral bone of the femoral head and the acetabulum.

OBJECTIVE—To assess the effect of standing position on joint space width (JSW) measurements of the hips with and without osteoarthritis (OA) on pelvic radiographs. METHODS—Adult patients aged 18 or more had pelvic anteroposterior conventional ...

2024年5月16日 · Joint space narrowing of the hip is a common term used in orthopedics to describe a condition where the gap between the bones in the hip joint becomes smaller or narrower over time. This narrowing can be the result of various underlying causes, such as arthritis, injury, or age-related wear and tear.

2019年4月23日 · When joint space narrowing occurs, the cartilage no longer keeps the bones a normal distance apart. This can be painful as the bones rub or put too much pressure on each other. Joint space...

2003年5月1日 · Quantification of progressive narrowing of the radiographic joint space width (JSW) in the hip is a validated method to evaluate osteoarthritis (OA) longitudinally. Among patients with OA, even asymptomatic OA hips have been shown to undergo progressive narrowing over time 1.
