Chapter 10: Arthritic Disorders ~Shareefah’s Review~ General Arthritic Information -Arthritis costs American economy more than 14 billion per year; affects 1 in every 7 people -3 Types of Joints: fibrous, cartilaginous and synovial -Normal appearance of synovial joints: thin articular cortex and uniform joint space -Bare areas: regions where synovium lies in direct contact with intra-articular bone not covered by cartilage Predisposed to bone erosion from synovial disease -3 basic types of arthritis: Inflammatory, Degenerative, Metabolic (know chart on pg. 956) -Definitions Spondylosis: spinal degeneration and deformity of the joint of 2 or more vertebrae Bony ankylosis: union of bones in a joint -Inflammatory: Soft tissue swelling, edema, uniform loss of joint space, bone erosions, juxta-articular osteoporosis Monoarticular of Polyarticular Greater disposition to bony ankylosis w/ inflammatory arthritis than any other type Ex. Rheumatoid Arthritis, Psoriasis, Ankylosing Spondylitis, Reiter’s Syndrome -Degenerative: Non uniform loss of joint space, osteophytes, subchondral sclerosis, subchondral cysts, asymmetric Ex. Degenerative Joint Disease aka Osteoarthritis -Metabolic: Soft tissue masses w/in periarticular soft tissues, well-marginated bone lesions, relative preservation of joint space. Ex. Gout, Amyloidosis (far less common) Degenerative Joint Disease aka Osteoarthritis (pg. 958); capsule summary pg. 987 Non-inflammatory degeneration of joint cartilage with secondary effects on adjacent bone Radiological Features : Asymmetric Distribution Non-inflammatory Non-uniform loss in joint space Osteophytes Subchondral Sclerosis (Eburnation) Subchondral cysts (geodes) Intra-articular loose bodies (most common in the knee) Articular deformity Joint subluxation -DJD: more common in males until age 45 -Most common sites: weight bearing joints/articulations
