TYPICAL RADIOGRAPHIC FEATURES OF OSTEOARTHRITIS

  1. 1. TYPICAL RADIOGRAPHIC FEATURES OF OSTEOARTHRITIS Focal joint space narrowing Subchondral sclerosis Marginal osteophyte Subchondral cyst The plain radiograph remains a key investigation in the clinical management of OA the diagnosis of OA the assessment of the severity of structural damage the search for associated chondrocalcinosis The four radiographic features of OA are: It is useful for: provided by Pascal Richette
  2. 2. HIP OSTEOARTHRITIS - Joint space narrowing in the superior weight-bearing portion of the joint (1) - Central osteophyte, adjacent to the fovea (2) - Marginal osteophyte visible on the inferior margin of the femoral head (3) (1) (2) (3) provided by Pascal Richette
  3. 3. KNEE OSTEOARTHRITIS -tibio-femoral compartments- - Medial tibiofemoral narrowing in both knees (arrow) -Note the mild subchondral sclerosis adjacent to the narrowing in the upper part of the medial tibial plateau, and the absence of well identified osteophyte. provided by Pascal Richette
  4. 4. KNEE OSTEOARTHRITIS ASSOCIATED WITH CHONDROCALCINOSIS - Articular chondrocalcinosis is characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in articular cartilage. - Note the calcification deposited in both menisci (arrow) provided by Pascal Richette
