Study Notes
Plane Joints
- Allow slight movement
- Have flattened or slightly curved surfaces that slide across each other
- Movement is limited and nonaxial
- Examples: Acromioclavicular, claviculosternal, intercarpal, vertebrocostal, sacro-iliac joints
Hinge Joints
- Permit angular motion
- Have a single plane of movement, like opening and closing a door
- Movement is monaxial
- Examples: Elbow, knee, ankle, interphalangeal joints
Condylar Joints
- Allow angular motion
- Are biaxial, meaning they move in two planes
- The oval articular face fits within a depression on the opposite surface
- Examples: Radiocarpal, metacarpophalangeal (joints 2-5), metatarsophalangeal
Saddle Joints
- Allow angular motion
- Have complex, complementary articular faces
- Movement is biaxial, meaning it moves in two planes
- Articular faces fit together like a rider in a saddle
- Example: First carpometacarpal (thumb) joint
Pivot Joints
- Allow only rotational movement
- Movement is monaxial
- Example: Atlanto-axial joint (head rotation), proximal radioulnar joint (allows the radius to rotate)
Ball-and-Socket Joints
- Allow extensive movement
- Movement is triaxial
- Round head of one bone fits into a cup-shaped depression of another
- Examples: Shoulder joint, hip joint
Intervertebral Joints
- The first two cervical vertebrae (atlas and axis) are joined by a synovial joint
- Synovial joints are between adjacent articular processes
- Adjacent vertebral bodies form symphyses (cartilaginous joints)
Knee Joint
- Ligaments that stabilize the knee joint include:
- Tibial collateral ligament
- Fibular collateral ligament
- Popliteal ligaments
Hip Joint
- Ligaments that stabilize the hip joint include:
- Iliofemoral
- Pubofemoral
- Ischiofemoral
- Transverse acetabular
- Ligament of the femoral head
Effects of Aging on Joints
- Degenerative changes that happen with age:
- Rheumatism: pain and stiffness in the musculoskeletal system
- Arthritis (joint inflammation): a broad term referring to all rheumatic diseases that affect synovial joints
- Osteoarthritis: wear and tear of joint surfaces or genetic factors affecting collagen formation
- Rheumatoid arthritis: an inflammatory condition where the immune system attacks joint tissues
- Gouty arthritis: crystals of uric acid form within synovial fluid
- Joint immobilization: reduces flow of synovial fluid and can lead to arthritic symptoms
- As we age: bone mass decreases, bones weaken, and the risk of fractures increases
Continuous Passive Motion (CPM)
- Treatment method to help with recovery from joint injuries or surgeries
- Promotes joint motion and circulation without requiring the patient to move the joint themselves
- Helps prevent stiffness and improve healing
