TermDefinition
Hinge Joint a joint that has rocker and craddle components, which allow extension and flexion only (the elbow)
Saddle Joint a joint in which two components have a complementary convex-concave shape, and the bones slide over each other. (only 1 of these joints, the thumb)
Gliding Joint a joint in which relatively flat surfaces of the bone slide over each other (the vertebrae, movement of which allows the spine to flex)
Ball-and-socket joint a joint with a spherical component and a concave component. movement occurs in several planes making this the most freely movable joint (hip and humerus)
Pivot Joint a joint composed of a bony protuberance and an open collar component (1st and2nd vertebrae of the neck)
Condyloid Joint a joint in which a small protrusion slides within a slightly elliptical component (carpal bones of the wrist)
Tendons attach muscle to bone
Ligaments attach bone to bone
Orthopedic Table 'fracture table'. used mainly for the surgery of the femur and the lower leg. it supports the operative leg while providing open access to the femur.
Pneumatic Tourniquet provides a bloodless operative site by blocking the flow of blood. its components include the cuff, regulator, and tubing.
Esmarch Bandage used to exsanguinate the limb
Bone Putty 'ostene'. a moldable preparation that is pressed into bleeding areas to control oozing.
Open reduction and internal fixation (ORIF) involves open surgery and to expose the bone and reduce the fracture (akign the bones in anatomical position). internal orthopedic implants are used to achieve fixation.
Open reduction and external fixation (OREF) reduction requires an incision to align the bones. however, an external device (frame or cast) is used to stabilize and hold the bone fragments during healing.
Closed reduction and external fixation (CREF) the fracture is reduced manually or with a traction device. except for casting and other types of noninvasive splinting, this type of fixation device requires the insertion of wires, pins, or other devices to support the external structures.
Inert a material that does not react with other nonorganic or biological substances
Skin Traction requires taping a traction system to the skin.used only as a temporary measure (buck traction). seldom used in adults.
Skeletal Traction requires surgical insertion of metal pins or rods through the bone distal to the fracture. the pins are attached to a traction device that applies force or is drawn by a weighted pulley.
Tamponade pressure to control bleeding
Labrum rim of cartilage that that surrounds the socket and helps stabilize the head of the humerus.also attaches to several ligaments which further support the joint
Clavicle moves in coordination with the humerus and is a primary site of sports injuries
Acromioclavicular (AC) Joint clavicle to acromion
Sternoclavicular (SC) Joint clavicle to sternum
Rotator Cuff composed of four tendons / muscles that attach the humerus to the glenoid socket
Femoral Head includes the stem, neck, and head
Acetabular Components includes an acetabular liner, which is seated into the prepared acetabulum and a shell which fits into the liner
Osteoarthritis results in the loss of cartilage and eventual erosion of bone
Osteonecrosis death of bone and marrow tissue, usually related to trauma or disease
Acetabular Fracture hip trauma, commonly associated with falls and motor vehicle accidents
Femoral Neck Fracture commonly associated with falls
Avascular Necrosis death of bone tissue related to the interruption of blood supply to the hip
