Study Notes
Concave-Convex Rule
- Un surface de jointo es MOBILE e un es STABLE.
- Quando le jointo concave se move super un surface convex stationary, le os move in le mesme direction del movimento del segmento corporal; le glide ocurre in le mesme direction como le roll.
- Quando le jointo convex se move super un surface concave stationary, le glide ocorre in le direction OPPOSITE al movimento del os.
Glenohumeral Joint
- Jointo convex: humerus (component movable).
- Jointo concave: glenoid.
- Movimento: le direction del humerus es opposite al direction del glenoid.
Ulnohumeral Joint
- Function: flexion e extension.
- Jointo convex: humerus.
- Jointo concave: ulna.
- Movimento: ulna se move in le mesme direction como le humerus.
Radiohumeral Joint
- Function: flexion e extension.
- Jointo convex: humerus.
- Jointo concave: radius.
- Movimento: radius se move in le mesme direction como le humerus.
Proximal Radioulna Joint
- Function: pronation e supination.
- Jointo convex: radius, jointo concave: ulna.
- Movimento: radius se move in direction opposite al ulna.
Distal Radioulna Joint
- Function: pronation e supination.
- Jointo convex: ulna, jointo concave: radius.
- Movimento: radius se move in le mesme direction como le ulna.
Radiocarpal Joint
- Jointo convex: carpal.
- Jointo concave: radius.
- Function: flexion e extension.
- Movimento: carpal se move in le direction opposite al radius.
Metacarpophalangeal Joints
- Function: abduction e adduction.
- Jointo concave: phalanges, jointo convex: metacarpals.
- Movimento: phalanges se move in le mesme direction como le metacarpals.
Interphalangeal Joints
- Jointo convex: proximal phalanges, jointo concave: distal phalanges.
- Movimento: se move in le mesme direction.
Hip Joint
- Jointo convex: femur, jointo concave: acetabulum.
- Movimento: femur se move in direction opposite al acetabulum.
Tibiofemoral Joint
- Jointo convex: patella, jointo concave: femur.
- Movimento: femur e fibula se move in la mesme direction.
Patellofemoral Joint
- Jointo convex: patella, jointo concave: femur.
- Movimento: patella se move in direction opposite al femur.
Proximal Tibiofibula Joint
- Jointo convex: tibia, jointo concave: fibula.
- Movimento: fibula se move in la mesme direction.
Distal Tibiofibula Joint
- Jointo convex: fibula, jointo concave: tibia.
- Movimento: fibula se move in direction opposite al tibia.
Talocrural Joint
- Jointo convex: talus, jointo concave: tibia e fibula.
- Movimento: talus se move in direction opposite al tibia e fibula.
Subtalar Joint
- Convex anterior e medio talus, concave anterior e medio calcaneus se move in le mesme direction.
- Convex posterior calcaneus, concave posterior talus se move in direction opposite.
Intermetatarsal Joint
- Jointo concave se move super jointo convex: metatarsals mediales convex, phalanges laterales concave.
Metatarsophalangeal Joint
- Jointo concave: phalanges, jointo convex: metatarsals.
- Movimento: se move in la mesme direction.
Interphalangeal Joints of the Toes
- Jointo concave: phalanges, jointo convex: metatarsals.
- Movimento: se move in la mesme direction.
Classifications of Joints
- Joints con fixed concave e moving convex surfaces se move in direction opposite (ex. Glenohumeral, Hip, Proximal Radioulnar).
- Joints con fixed convex e moving concave surfaces se move in la mesme direction (ex. Ulnohumeral, Radiohumeral, Tibiofemoral).
