Xray of normal and degenerative hip4/16/2024 ![]() ![]() Lespasio MJ, Piuzzi NS, Husni ME, Muschler GF, Guarino A, Mont MA. Prognostic factors for progression of osteoarthritis of the hip: a systematic review. Teirlinck CH, Dorleijn DMJ, Bos PK, Rijkels-Otters JB, Bierma-Zeinstra SMA, Luijesterburg PAJ. Glucosamine and chondroitin sulfate: what has been learned since the Glucosamine/Chondroitin Arthritis Intervention Trial. TGF-β signaling and the development of osteoarthritis. One must always do X-rays based on several views to better assess the joint space but by limiting the views actually needed to minimise the amount of exposure delivered to the patient.Lespasio MJ. Potential narrowing may fade completely when the body is relieved of body weight and mislead the diagnosis. Indeed, in a standing position, the joint space narrows a little more because of the stress to the skeleton imposed by the weight of the body. In the lower limbs (especially the knee), the X-rays should be made in a position of constraint, preferably supporting body weight. This scenario is relatively common for example in hip osteoarthritis. In addition, taking an X-ray of two symmetrical joints sometimes enables discovering an bilateral impairment that is asymptomatic on one side. Indeed, when the X-ray reveals an abnormal image, if it is bilateral, it may be an anomaly with no clinical significance. One must always X-ray the two symmetrical joints in order to compare the pathological side to the asymptomatic side presumed healthy. There are some key principles of standard osteoarticular radiography: This type of scoring can be used to assess the progression of osteoarthritis and can be applied to many joints. Grade 0 corresponds to a normal X-ray and grade 4 to complete loss of cartilage. It comprises 4 grades: doubtful, moderate, definite and severe osteoarthritis. This is an index that takes into account the osteophytes and joint space narrowing. The Kellgren and Lawrence grading scale is the most commonly used. In standard radiography several scores enable classifying patients according to the severity of their illness. Close radiological monitoring may therefore be necessary. Repeated inflammatory flare-ups of osteoarthritis in the lower limbs may be related to a rapid chondrolysis. Measuring joint space is used to evaluate narrowing. Structural monitoring is done by X-ray every 18 to 24 months. Standard radiography also enables monitoring the structural evolution and thus constitutes one of the elements of the prognosis of the osteoarthritic disease. and signs of complications such as secondary synovial osteochondromatosis. The X-rays are used to find the aetiological factors of osteoarthritis such as dysplasia for the hip, chondrocalcinosis, traumatic after-effects, etc. Search for the aetiological factors of osteoarthritis In most cases, standard radiography remains the appropriate tool for the diagnosis of osteoarthritis. Zygapophysial osteoarthritis is revealed by condensation of the facet joints, joint space narrowing on three-quarter views, osteophytes, remodelling and horizontalization of joint surfaces, sometimes responsible with disc degeneration of spondylolisthesis. In the event of joint space narrowing without osteophytes the diagnosis may be more difficult and require additional imaging examinations.ĭiscarthrosis results in overall or localised narrowing of the intervertebral disc space, subchondral condensation and osteophytes on the vertebral endplates. The first two signs are sufficient to consolidate a diagnosis often sensed clinically. ![]() They are most often located in the area of epiphyseal osteocondensation of the subchondral bone. Epiphyseal or "hyper-pressure" geodes, rounded or oval size.It is necessary to assess where it is localised and how significant it is. This primarily reflects a reduction in thickness of the cartilage and its deterioration. Localised joint space narrowing, usually asymmetrical.The radiographic diagnosis of osteoarthritis is based on 4 signs that may be isolated or associated with one another: ![]()
