Repetitive overhead throwing exerts significant mechanical stress on the shoulder and elbow joint; this stress can lead to developmental anatomic changes in the young thrower. Asymptomatic pathology in the shoulder and elbow joint is prevalent and, with overuse, can progress to disabling injury. Joint injury occurs as a result of the body's inability to properly coordinate motion segments durin...

Baseball is one of the most popular sports in the United States, with estimates of 4.8 million children 5 to 14 years of age participating annually in organized and recreational baseball and softball. Interest in and fascination with the sport have grown since the beginning of the 20th century, but it was not until 1965 that the issue of “Little League elbow” raised concern about the safety of ...

Background Although much literature exists regarding the treatment and management of elbow dislocations in the general population, little information is available regarding management in the athletic population. Furthermore, no literature is available regarding the postinjury treatment and timing of return to play in the contact or professional athlete. Purpose To review the clinical course o...

We compared the quantitative electromyographic activity of the elbow flexors during four exercises (forced inspiration, forced expiration, trunk flexion and attempted elbow flexion), following intercostal nerve transfer to the musculocutaneous nerve in 32 patients who had sustained root avulsion brachial plexus injuries. Quantitative electromyographic evaluation of the mean and maximum amplitud...

In children, traumatic elbow dislocations usually occur after the epiphysis has closed and with associated radial head and neck fractures and osteochondral fragments. The fragments are also usually interposed in the joint restricting complete congruent joint motion. We report on 3 children with traumatic elbow fracture-dislocation with associated radial head and neck injuries treated with open ...

Elbow injuries continue to rise with increased athletic activity and life expectancy. Knowledge of anatomy and biomechanics of this sophisticated joint, various injury patterns, and the implication of injury to the static and dynamic stabilizers will result in improvement in specific diagnosis, and therapy. The surgical treatment of trauma to the adult elbow has evolved rapidly in recent years ...

Normal variations in anatomy in the skeletally immature patient may be mistaken for fracture or injury due to the presence of secondary centers of ossification. Variations in imaging exist from patient to patient based on sex, age, and may even vary from one extremity to the other on the same patient. Despite differences in the appearance of the bony anatomy of the elbow there are certain landm...

Radial head fractures are common, accounting for approximately one-third of all elbow fractures, with an estimated incidence of 2.5 to 2.9 per 10.000 people per year (1-3). They generally occur after a fall on the outstretched arm. They may be isolated or associated with more complex injuries such as fractures of the olecranon or coronoid process, elbow dislocation, ligament rupture, vascular i...

In this paper, based on the finite element method, stresses of radius and ulna are analyzed at different flexion angles elbow when playing tennis. The model is presented for position with 0°, 25°, 60°, 80° according to normal human arm bone. model, whole metacarpals, radius, ulna, humerus scapula considered. calculation simplified by setting metacarpals as rigid bodies using Tie binding constra...
