The ulnar collateral ligament (UCL) is the primary static restraint to valgus stress at the elbow. Since Jobe pioneered reconstruction in 1974, thousands of throwers have undergone UCL reconstruction, and good results have been achieved. The high-profile nature of the elite pitcher has brought this technique into the spotlight, and extensive research has been performed with new techniques emerging. The standard reconstruction, modified only slightly since Jobe's original description, remains the gold standard for treatment of UCL insufficiency...

The patient was an 18-year-old collegiate baseball pitcher who injured his right throwing elbow during an overhead slider pitch. As a part of a study, preinjury ultrasound images of the throwing arm were obtained 2 weeks prior to the injury. One day postinjury, repeat ultrasound imaging of the medial elbow was performed. The attending team physician ordered a magnetic resonance arthrogram 2 days after injury, which confirmed the presence of a complete tear of the ulnar collateral ligament.

We describe an unusual case of acute ulnar neuropathy with a flexible claw hand deformity in a baseball pitcher. Treatment involved ulnar nerve decompression at the elbow with subsequent recurrence of symptoms upon return to pitching. Definitive treatment included a wide secondary release of tethered locations resulting in return of function. At final follow-up the patient has returned to unrestricted baseball throwing activities.

BACKGROUND: A glenohumeral internal rotation (IR) deficit or a total rotational motion (IR plus external rotation [ER]) deficit in the throwing shoulder compared with the nonthrowing shoulder has been shown to increase the risk of shoulder and elbow injuries. After a pitching session, both IR and total rotational motion deficits have been shown to occur naturally for an extended period of time in asymptomatic pitchers, but it is unclear how to best control these deficits between pitching sessions...

Increased physical activity in childhood has resulted in a large number of sports-related injuries. Although there is overlap between the sports-related injuries seen in pediatric and adult patients, important differences exist in the injury patterns of pediatric patients. These differences are related to the continuous changes in the developing skeleton and its relationship with adjacent soft tissues. The imbalance in strength between the growing bones and the nearby tendons and ligaments makes the bones prone to acute and chronic injuries...

Video recordings are used to quantitatively analyze pitchers' techniques. However, reliability and validity of such analysis is unknown. The purpose of the study was to investigate the reliability and validity of joint and segment angles identified during a pitching motion using video analysis. Thirty high school baseball pitchers participated. The pitching motion was captured using 2 high-speed video cameras and a motion capture system. Two raters reviewed the videos to digitize the body segments to calculate 2-dimensional angles...

The windmill softball pitch generates considerable forces about the athlete's shoulder and elbow. The injury pattern of softball pitchers seems to be primarily overuse injury, and they seem not to suffer the same volume of injury that baseball pitchers do. This article will explore softball pitching techniques, kinetics and kinematics of the windmill pitch, epidemiology of softball pitchers, and discuss possible etiologies of softball pitching injuries.

Benjamin L Oshlag, Tracy R Ray
Baseball pitchers and other throwing athletes place their elbows under tremendous stresses, making them vulnerable to a number of unique injuries. Skeletally immature throwers in particular are at a greater risk for growth plate and other bony injuries, due to the relative strengths of these tissues and the kinematics involved in throwing. Care should be taken to fully evaluate these injuries based on the particular history and presentation to properly direct treatment and rehabilitation. Patients, as well as other athletes, coaches, and families, also should be made aware of the significant risk factors for these injuries, especially those regarding pitch limits, proper mechanics, and sufficient rest...
