What is a Bicondylar joint?
The condylar joint is better called bicondylar, for in it two distinct surfaces on one bone articulate with corresponding distinct surfaces on another bone. The two male surfaces are on one and the same bone and are of the same type (ovoid or sellar). Bicondylar joints are quite common. …
What are Diarthrotic joint?
Diarthrosis. A freely mobile joint is classified as a diarthrosis. These types of joints include all synovial joints of the body, which provide the majority of body movements. Most diarthrotic joints are found in the appendicular skeleton and thus give the limbs a wide range of motion.
What is ellipsoid joint in anatomy?
Anatomical terminology A condyloid joint (also called condylar, ellipsoidal, or bicondylar) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction.
How does an ellipsoid joint work?
Ellipsoid joints allow back and forth and side to side movement. Such joints occur between the metacarpals and phalanges (between the bones of the hand and the bones of the finger) as seen in the adjacent image.
What is a Bicondylar fracture?
Bicondylar tibial plateau fractures are complex injuries that are frequently difficult to treat. Bicondylar plateau fractures involve some portion of both the medial and lateral articular surfaces, with associated disruption of the articular fragments from the metaphysis.
Which of the following joints is classified as Bicondylar?
temporomandibular joint (TMJ) a bicondylar joint formed by the head of the mandible and the mandibular fossa, and the articular tubercle of the temporal bone.
What is an example of a diarthrosis joint?
Joints allowing full movement (called diarthroses) include many bone articulations in the upper and lower limbs. Examples of these include the elbow, shoulder, and ankle.
What are the specific types of Diarthrotic joints?
There are six types of freely movable diarthrosis (synovial) joints:
- Ball and socket joint. Permitting movement in all directions, the ball and socket joint features the rounded head of one bone sitting in the cup of another bone.
- Hinge joint.
- Condyloid joint.
- Pivot joint.
- Gliding joint.
- Saddle joint.
What is the difference between ellipsoid and saddle joint?
A saddle joint is a modified ellipsoidal joint, but with a pair of bones in a rider and saddle shape. The first metacarpal (of the thumb) and the trapezium (on of the carpals) form just such a joint. A saddle joint has a much wider range of flexibility, including movement on two axes (biaxial).
What type of joint is ellipsoid?
A synovial joint in which an oval-shaped process of one bone fits into an elongated or ellipsoidal cavity of the other, allowing movements such as flexion, extension, abduction and adduction.
What is Bicondylar fracture of right tibia?
Bicondylar tibial plateau fractures often have bone defects due to compression of the cancellous subchondral bone. After reduction of the articular fragments, options for filling the metaphyseal bone defects include iliac crest autograft, allograft and bone substitutes such as calcium phosphate and hydroxyapatite.
