Post-traumatic Stiffness: Injury to the elbow and forearm can often lead to post-injury stiffness. It is not uncommon to see someone who had severe elbow pain from tennis elbow do very well for 3 months after an injection only to have the pain return at twice the initial intensity. Definition bunion Term rhutmic disease that affect synovial joints result in the development of Definition arthritis Term a rigid cartliganeous connection such as an epiphyseal plate is called a Definition synchondrosis Term the amphiarthrotic distal articulation between the tibia and fibula is Definition syndosmosis Term the joint accessory structur that may subdivide a synovial cavity Definition menisci Term what provides protection for articular cartilages Definition fat pads Term arthritis always involves damage to the Definition articular cartilage Term movement that allows you to gaze at ceiling? These variations occurred on the medial side in 50% of the 39 cadaveric elbow joints and on the lateral side in 25%. It stabilizes the lateral muscles and helps prevent bow shock transmission into the elbow. Depending on our age and chosen activity, any one of the structures mentioned can breakdown and become a cause of elbow pain.

Definition elbow Term extremely stable joint that is almost completely enclosed in a bony socket is the: Definition hip joint Term the joint that contains three seperate articulations with an incomplete capsule is the. The ulnar parts of the collateral ligaments are taut throughout the range of motion, whereas the radial parts are lax in flexion, allowing an increased range of rotation of the radial head 4. This conjoined tendon became taut with the forearm upon supination. Do this exercise about 20 times without increasing the pain. Goodrich, in , 2014 Anatomy The elbow joint is composed of the articulation between the distal humerus and the proximal radius and ulna.

Some people are born with greater laxity or looseness in their ligaments. A supination B pronation C dorsiflexion D opposition 20 Protraction is a movement of a body part in which direction? Supracondylar fractures 2 If there is only minimal or no displacement these fractures can be occult on radiographs. The only direct connection between the pectoral girdle and the axial skeleton is where Tire head of the humerus articulates with the The ligament that provides support to the front of the knee joint is The bones that form the fingers are the The bones that give the hand a wide range of motion are the The three functions of synovial fluid are The smallest facial hones are the The function of the hyoid bone is to Nerves earning sensor, information from the lips and the chin pass through the The largest sinus is within which bone? These fractures must be carefully monitored as they have a tendency to displace. Distally the capsule is attached to the margins of the trochlear notch of the ulna and the annular ligament. The scapula has four centers of ossification: the scapular cartilage, body of the scapula, cranial part of the glenoid cavity of the scapula, and supraglenoid tubercle and coracoid process.

A complete elbow dislocation is acute, extremely painful, and very obvious. If blood vessel or nerve injuries are associated with the elbow dislocation, additional surgery may be needed to repair the blood vessels and nerves and repair bone and ligament injuries. The anterior bundle is the strongest and most distinct component, whereas the posterior bundle exists as a thickening of the posterior capsule and provides stability at 90 degrees of flexion. A simple dislocation does not have any major bone injury. It is done gently and slowly. Proper radiographic technique is mandatory for visualization of this triangular opacity in the lateral view Figures 4-36 and 4-37.

In these cases a joint salvage procedure, such as elbow arthrodesis, may be a better choice. So the next question is where is the medial epicondyle? The elbow becomes locked in hyperextension. Physical therapy can be helpful during this period of recovery. Is there a subtle fracture? The capsular attachment on the humerus extends from the outer margins of the capitulum and trochlea upwards to enclose the olecranon fossa posteriorly and the coronoid fossa and radial fossa anteriorly Figs 2. In younger patients, sickle cell disease is the most common cause of osteonecrosis of the elbow. The cast or fracture brace will remain in place until the fracture shows signs of healing. Over time, there is an increased risk for arthritis in the elbow joint if the alignment of the bones is not good; the elbow does not move and rotate normally; or the elbow continues to dislocate.

Is there a sign of joint effusion? The ulnar part of the medial collateral ligament is also broader than the radial part of the medial collateral ligament 4, 5.

Note the lateral position of the radius, a landmark for distinguishing the lateral versus medial sides of the elbow joint in craniocaudal views. The triceps muscle group, the major extensor of the elbow joint, arises from the caudal aspects of the scapula and the humeral shaft and attaches onto the olecranon process of the ulna. If the elbow is kept immobile for a long time, the ability to move the elbow fully range of motion may be affected. Also want to determine whether there have been previous attempts at remobilization, and to identify the factors that may contribute to stiffness. Definition scapulohumeral Term radial, ulnar, and annular collateral ligaments provide stability for which joint? Definition Sliding and rotation are prevented , and angular motion is restricted to two directions Term The type of joints that the connect the fingers and toes with the metacarpals and metatarpel are: Definition ellipsoidal biaxial synovial Term what are examples of angular motion? Pulses at the neck and the wrist will be checked.

The craniodistal pull of the biceps brachii results in cranial and distal displacement of fractures of the supraglenoid tubercle. The hollow white arrowhead is the most cranial aspect of the medial coronoid process. This surgery removes scar tissue and extra bone growth. Optimal radiographic technique is needed to identify this structure in this view. Partial dislocations can continue to recur over time if the ligaments never heal. Please consult your health care provider, or contact Great Lakes Orthopedics for an appointment, before making any healthcare decisions or for guidance about a specific medical condition.

The small amount of joint effusion is probably the result of the prior dislocation. The medical term for this is lateral epicondylitis. The other static stabilisers are the anterior joint capsule, the medial and lateral collateral ligaments and the interosseous membrane. This view positions the medullary cavity of the ulna over the central aspect of the humeral condyle. The anconeal process is an early site for the development of degenerative joint disease. The tendon of biceps brachii is partially cartilaginous proximally and passes over the smooth intertuberal groove of the humerus and then becomes predominantly muscular with a tendonous core.

If there is no displacement it can be difficult to make the diagnosis figure. In addition, the elbow is stabilized by ligaments on the outside lateral and inside medial elbow. In B1, the dotted black line reflects the medial margin of the proximal radius. In the most severe dislocations, the blood vessels and nerves that travel across the elbow may be injured. The physes associated with the distal humeral condyle and medial epicondyle can complicate radiographic interpretation in the young patient Figure 4-39. When the joint surfaces of an elbow are separated, the elbow is dislocated. If the elbow is kept immobile for a long time, the ability to move the elbow fully range of motion may be affected.
