Functional Classification of Joints
(1) Synarthroses (Immovable)
(2) Amphiarthrosis (Slightly movable)
(3) Diarthroses (Fully movable)
Structural Classification of Joints
(1) Fibrous: (bone ends united by collagen)
sutures, syndesmoses, gomphoses
(2) Cartilaginous: (bones united by cartilage)
synchondrosis, symphyses, synovial joints
Flexion, Extension, Hypertension
Flexion- bent knee
Hypertension-bring leg back
Rotation, Lateral rotation, Medial rotation
Lateral rotation- twisting out
Medial rotation- twisting in
Disorders and Imbalances: Sprain
Sprain type 1- stretched ligament
Sprain type 2- ligaments torn slightly
Sprain type 3- ligaments torn completely
Degenerative joint disease, non-inflammatory, only cartilage affected, deterioration of cartilage produces bone spurs and restricts movements, pain upon awakening and lessens with movement.
Uric acid crystals build up in joints-pain.
waste products of metabolism build up and deposited in cartilage causing inflammation and swelling. bones fuse.
Autoimmune disorder, cartilage attacked by immune system, inflammation and swelling, pain, joint fusion
replacement of joint, total hip replaces acetablum and head of femur, plastic socket and metal head, knee replacement.
