Background Joint pain is thought to be an early sign of injury to a pitcher. Objective To evaluate the association between pitch counts, pitch types, and pitching mechanics and shoulder and elbow pain in young pitchers. Study Design Prospective cohort study. Methods Four hundred and seventy-six young (ages 9 to 14 years) baseball pitchers were followed for one season. Data were collected from pre- and postseason questionnaires, injury and performance interviews after each game, pitch count logs…

Risk Factors for Shoulder and Elbow Injuries in Adolescent Baseball Pitchers
TLDR
The factors with the strongest associations with injury were overuse and fatigue, and high pitch velocity and participation in showcases were also associated with increased risk for injury.

TLDR
In their second game-by-game study of arm problems in youth baseball, researchers followed 476 young pitchers during the 1999 season and suggested that breaking pitches and high pitch counts—but not pitching mechanics—may be the culprits behind elbow and shoulder pain in young baseball players.
Association of Maximum Pitch Velocity and Elbow Injury in Professional Baseball Pitchers
TLDR
A statistically significant association between maximum pitch velocity and elbow injury was noted in this study, providing further support of existing theories about injury in baseball.
The Effect of Pitching Biomechanics on the Upper Extremity in Youth and Adolescent Baseball Pitchers
TLDR
Youth pitchers with better pitching mechanics generate lower humeral internal rotation torque, lower elbow valgus load, and more efficiency than do those with improper mechanics.
A Biomechanical Comparison of the Fastball and Curveball in Adolescent Baseball Pitchers
TLDR
The findings based on the kinematic and kinetic data in this study suggest that the rising incidence of shoulder and elbow injuries in pitchers may not be caused by the curveball mechanics.
Relationship Between Pitch Volume and Subjective Report of Injury in High School Female Fast-Pitch Softball Pitchers.
TLDR
High pitching volumes commonly prevalent in high school-aged softball pitchers may be associated with increased pain/injury and appear related to cumulative volume.
Fast-Pitch Softball Pitchers Experience a Significant Increase in Pain and Fatigue During a Single High School Season
TLDR
Fast-pitch softball pitchers experience increased pain and fatigue during a single game and over the entire season, and the increase in fatigue may predispose the player to injury.
The Influence of Pitch Velocity on Medial Elbow Pain and Medial Epicondyle Abnormality Among Youth Baseball Players
TLDR
Pitch velocity was significantly associated with abnormality of the medial epicondyle and elbow pain and was significantly related with past pain, present pain, and past and/or present pain of the elbow.
Risk factors for shoulder and elbow pain in youth baseball players
TLDR
History of elbow pain, pitcher position, catcher position, and longer training hours per week were associated with both types of pain, and history of shoulder pain was associated with shoulder pain but not elbow pain.

Longitudinal study of elbow and shoulder pain in youth baseball pitchers.
TLDR
Arm complaints are common, with nearly half of the subjects reporting pain, and the factors associated with elbow and shoulder pain were different, suggesting differing etiologies.

TLDR
Better medical supervision and stress on prevention are needed, especially in the Southern California area where climatic conditions favor prolonged seasons and throwing practice the year around.

The purpose of this study was to establish and compare kinematic data among fourgroups of collegiate pitchers who threw the fastball (FA), change-up (CH), curveball(CU), and slider (SL). Twenty-six

1. In a study of 595 Little League pitchers, approximately 17% had a history of elbow symptoms: only 1% had elbow symptoms which had ever excluded them from pitching. There was no correlation between
The effect of competitive pitching on the shoulders and elbows of preadolescent baseball players.
TLDR
Clinical and radiological observations made on a group of 49 preadolescent pitchers who participated in a low-competition, recreational baseball program are reported and it is believed that the pread adolescent should avoid pitching in an intensely competitive situation.
Biomechanics of pitching with emphasis upon shoulder kinematics.
TLDR
In rehabilitation of injured throwers, there is a need to appreciate the highly dynamic nature of this skill and to attempt to simulate these dynamic motions and loads as part of the final phase of treatment before the athlete returns to competition.
Osseous Adaptation and Range of Motion at the Glenohumeral Joint in Professional Baseball Pitchers *
TLDR
A comparison of the dominant shoulders of the two groups indicated that both external rotation at 90° and humeral head retroversion were significantly greater in the throwing group than in the nonthrowing group.
Little League survey: the Eugene study
TLDR
In a clinical and radiographic survey of the elbows of 120 pitchers ages 11 and 12, 20% were found to have symptoms, 10% flexion contractures, and 23% roentgenographic changes related to traction stresses on the medial side of the elbow, which represents a definite incidence of abnormal occurrence.
