Study Notes
Joints Overview
- Joints are connections where two or more bones meet, with or without movement.
- Classified based on tissue types between bones: fibrous, cartilaginous, and synovial.
Functional Classification of Joints
- Synarthroses: Immovable joints.
- Amphiarthroses: Slightly movable joints with shorter ligaments.
- Diarthroses: Freely movable joints with longer ligaments.
Structural Classification of Joints
- Fibrous joints: Bones connected by dense connective tissue, lacking a joint cavity.
- Gomphoses: "Peg-in-socket" joints, e.g., tooth in alveolar socket.
- Syndesmoses: Joints allowing some movement.
Synovial Joints and Movement
- Synovial joints permit gliding, angular movements, flexion, extension, abduction, adduction, and circumduction without axial rotation.
- Types of synovial joints include:
- Saddle joints: Reciprocal concavo-convex surfaces (e.g., carpometacarpal joint of the thumb).
- Ball and socket joints: Ball-shaped head fitting into a socket (e.g., shoulder and hip joints).
- Condyloid joints: Flexion, extension, abduction, adduction (e.g., radiocarpal joint).
Knee Joint Anatomy
- Largest and most complex joint, primarily a hinge.
- Compound and bicondyloid: femur and tibia each have two condyles.
- Femoropatellar joint shares a cavity; includes multiple bursae (e.g., prepatellar, suprapatellar).
Cruciate Ligaments in the Knee
- Anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) cross over each other, providing stability.
- ACL connects the anterior intercondylar area of tibia to the femur; PCL connects the posterior intercondylar area to the femur.
- Cruciate ligaments are commonly injured in sports like soccer and basketball.
Inflammatory and Degenerative Conditions
- Bursitis: Inflammation or infection of a bursa caused by trauma or repetitive friction.
- Types of bursitis include:
- Housemaid’s knee: Painful inflammation of the prepatellar bursa.
- Student’s elbow: Olecranon bursitis from prolonged elbow pressure.
Dislocation and Cartilage Injuries
- Dislocations involve bones being out of alignment.
- Torn cartilage, particularly meniscus injuries, can occur from compression and shear stress, requiring careful treatment due to limited healing capacity.
