Arie J van Duijn, Shawn D Felton
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.

BACKGROUND: Ulnar collateral ligament reconstruction (UCLR) has become a common procedure performed in overhead-throwing athletes of many athletic levels. PURPOSE/HYPOTHESIS: The purpose of this study was to determine whether clinical outcomes and return-to-sport (RTS) rates differ among patients undergoing UCLR based on graft choice, surgical technique, athletic competition level, handedness, and treatment of the ulnar nerve. We hypothesized that no differences would exist in clinical outcomes or RTS rates between technique, graft choice, or other variables...

BACKGROUND: Weighted-ball throwing programs are commonly used in training baseball pitchers to increase ball velocity. The purpose of this study was to compare kinematics and kinetics among weighted-ball exercises with values from standard pitching (ie, pitching standard 5-oz baseballs from a mound). HYPOTHESIS: Ball and arm velocities would be greater with lighter balls and joint kinetics would be greater with heavier balls. STUDY DESIGN: Controlled laboratory study...

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' technique. 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 two high-speed video cameras and a motion capture system. Two raters reviewed the videos to digitize the body segments to calculate two-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.

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...

BACKGROUND: Stress ultrasound (SUS) of the elbow has demonstrated changes in the anterior band of the ulnar collateral ligament (UCL) in professional and high school-aged pitchers. However, there have been no large reports correlating pitching history data with SUS changes in youth and adolescent baseball pitchers. HYPOTHESIS: Changes of the UCL on SUS will correlate with pitching volume in youth and adolescent baseball pitchers. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

BACKGROUND: Alteration of elbow range of motion (ROM) has been observed in baseball pitchers. This study aims to compare dominant elbow ROM between early-puberty, late-puberty, and young-adult pitchers. METHODS: We recruited 62 pitchers, consisting of 17 early-puberty (mean age 13.1 years old), 22 late-puberty (mean age 17.7 years old), and 23 young-adult players (mean age 19.4 years old). Dominant elbow ROMs was measured. One-way ANOVA was used to compare the differences in elbow ROM variables between 3 groups...

BACKGROUND: Few reports in the literature relate morphologic changes of the ulnar collateral ligament (UCL) to prior elbow symptoms. This study used ultrasonography (US) to assess the ulnohumeral joint space width, with and without stress, and elucidate morphologic changes of the UCL of the elbow in high school pitchers with and without a history of elbow symptoms. METHODS: Each of 122 high school baseball pitchers who underwent US of the medial aspect of both elbows completed a self-administered questionnaire related to the self-satisfaction score (0-100) for pitching performance and throwing-related elbow joint pain sustained during the prior 3 years...
