The posterior ligament is thin and membranous, and consists of transverse and oblique fibers. Above, it is attached to the humerus immediately behind the capitulum and close to the medial margin of the trochlea , to the margins of the olecranon fossa , and to the back of the lateral epicondyle some little distance from the trochlea.
The incidence rate of elbow dislocations is 5 to 6 per 100,000 persons per year. [24] [41] [43] Posterior dislocations are the most common type of elbow dislocations, comprising 90% of all elbow dislocations. [44] Wrist. Overall, injuries to the small bones and ligaments in the wrist are uncommon. [6] Lunate dislocations are the most common. [6 ...
If the next workout takes place during the supercompensation period, the body will advance to a higher level of fitness. If the next workout takes place after the supercompensation period, the body will remain at its base level. Sometimes a few workouts are intentionally made in the recovery period to try to achieve greater supercompensation ...
They account for approximately one third of all elbow fractures and are frequently associated with other injuries of the elbow. [2] [3] Radial head fractures are diagnosed by a clinical assessment and medical imaging. [2] [4] A radial head fracture is treated according to the severity of the injury and its Mason-Johnston classification ...
Posterior dislocations are uncommon, and are typically due to the muscle contraction from electric shock or seizure. [6] They may be caused by strength imbalance of the rotator cuff muscles. People with dislocated shoulders typically present holding their arm internally rotated and adducted, and exhibiting flattening of the anterior shoulder ...
Extension type of injury (70% of all elbow fractures) is more common than the flexion type of injury (1% to 11% of all elbow injuries). [4] Injury often occurs on the non-dominant part of the limb. Flexion type of injury is more commonly found in older children. Open fractures can occur for up to 30% of the cases. [3]
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
Elbow dislocations constitute 10% to 25% of all injuries to the elbow. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons. [30] Among injuries to the upper extremity, dislocation of the elbow is second only to a dislocated shoulder. A full ...
