C-reactive protein is a substance made mainly by the liver that rises in the blood when there is inflammation in the body. It is measured with a simple blood test. Clinicians use it as a general signal that the immune system is “active,” not as a diagnosis by itself. In orthopedics, it is commonly used when evaluating possible infection or inflammatory causes of hip and joint symptoms.
CRP stands for C-reactive protein. It is a blood marker that rises when there is inflammation somewhere in the body. CRP is commonly used in emergency care, primary care, rheumatology, and orthopedics. In hip and joint care, it often helps clinicians evaluate possible infection or inflammatory disease.
CPPD hip refers to calcium pyrophosphate deposition (CPPD) disease affecting the hip joint. It involves microscopic crystals forming in and around joint cartilage, which can trigger inflammation. People may feel sudden hip pain (a “flare”) or gradual stiffness that resembles osteoarthritis. The term is most commonly used in orthopedics, rheumatology, radiology, and physical therapy documentation.
Coxa magna is an orthopedic term that means an enlarged femoral head (the “ball” of the hip joint). It is usually identified on hip X-rays or other imaging and compared with the opposite side. Coxa magna is a descriptive finding, not a standalone diagnosis. It is commonly used in pediatric and young-adult hip discussions, especially after certain childhood hip conditions.
Coxa breva is an orthopedic term that means a “short hip,” most often referring to a shortened femoral neck. It describes a shape difference in the upper femur (thigh bone) near the hip joint. Clinicians use it in radiology reports and hip evaluations to communicate anatomy clearly. It can be present from childhood conditions or develop after injury or surgery.
Coxa vara is a hip deformity where the femoral neck is angled more downward than typical. In plain terms, the “ball” of the hip sits on a “neck” that is tilted too low. It is a diagnostic term used in orthopedics and radiology to describe hip alignment on imaging. Clinicians use it to explain symptoms, guide monitoring, and plan treatment when needed.
Coxa valga is a hip alignment term that describes an increased angle between the femoral neck and the femoral shaft. In plain language, it means the “neck” of the thigh bone points more upright than usual. It is most commonly used in X-ray and orthopedic reports to describe hip shape and biomechanics. Clinicians use it in evaluating hip pain, gait changes, hip instability, and surgical planning.
Coxa saltans is the medical term for “snapping hip,” a sensation or sound of the hip catching, clicking, or snapping with movement. It is most often used in orthopedics, sports medicine, and physical therapy to describe a pattern of hip symptoms rather than a single disease. Some people notice snapping without pain, while others have pain or functional limits. The term helps clinicians organize evaluation and decide whether symptoms are likely coming from tissues outside or inside the hip joint.
Coxa profunda imaging describes how clinicians look for and interpret a “deep socket” appearance of the hip on medical images. It is most commonly discussed when reviewing plain X-rays of the pelvis and hips. The term helps radiologists and orthopedic clinicians communicate about acetabular (hip socket) coverage. It is often considered when evaluating hip pain, impingement-type symptoms, or structural hip anatomy.
Coxa profunda is an imaging term used to describe a “deep” acetabulum (hip socket). It is most commonly reported on an anteroposterior (AP) pelvis X-ray. The term helps clinicians discuss hip shape and possible socket overcoverage. It is descriptive, not a diagnosis by itself.
