CASE: A 16-year-old right-hand dominant male baseball player presented with little league shoulder in the setting of recombinant growth hormone utilization for growth hormone deficiency. After a prolonged treatment course, including physical therapy and throwing programs, the patient returned to baseball but suffered an ipsilateral proximal humerus fracture around the growth plate. CONCLUSION: The occurrence of such an injury in the context of human growth hormone treatment merits consideration in youth athletes undergoing similar treatment regimens...

Since elbow injuries are common in adolescent baseball players, this study aimed to determine the relationship between musculoskeletal status and elbow injuries in 47 baseball players aged 12-14 years. Participants answered a questionnaire and had their general body measurements taken. Magnetic resonance imaging was used to evaluate muscle cross sectional areas (CSA) of the upper arm flexor and extensor muscles, and x-ray absorptiometry was used to determine the mass of the upper arm and the total mass of the forearm and hand...

This study aimed to describe the injury profiles of young Korean baseball players according to position and age as the proportion and distribution of injuries based on playing position and age remains unclear. A total of 271 elite youth baseball players aged 8 to 16 years were divided into two groups: elementary school (ES) (n = 135) and middle school (MS) (n = 136). The participants' basic, baseball practice, and injury information were collected. Injuries in the MS group were not limited to the elbow and shoulder, and injury prevalence varied by age group and baseball position...

BACKGROUND: The literature has proven that plyometric training (PT) improves various physical performance outcomes in sports. Even though PT is one of the most often employed strength training methods, a thorough analysis of PT and how it affects technical skill performance in sports needs to be improved. METHODS: This study aimed to compile and synthesize the existing studies on the effects of PT on healthy athletes' technical skill performance. A comprehensive search of SCOPUS, PubMed, Web of Science Core Collection, and SPORTDiscus databases was performed on 3rd May 2023...

BACKGROUND: Previous studies have examined the timing of peak kinematic variables during the pitching cycle in high school, collegiate, and professional pitchers. These same variables have been studied less in younger populations. PURPOSE: To determine whether youth and adolescent baseball pitchers will experience peaks in certain kinematic variables at different times throughout the pitching cycle compared to professional/collegiate pitchers. STUDY DESIGN: Cross-sectional, descriptive study...

BACKGROUND: Increased shoulder distraction force during a baseball pitch may make a pitcher susceptible to rotator cuff or glenohumeral labral injuries. A precursor to a pitching injury may be pain experienced in the throwing arm. PURPOSE: To (1) compare peak shoulder distraction (PSD) forces in youth baseball pitchers with and without upper extremity pain when throwing a fastball and (2) assess if PSD forces across trials differ between pain and pain-free groups...

WhyWeRise is a social marketing campaign conducted by the Los Angeles County Department of Mental Health (LACDMH) to promote community engagement with mental health issues, reduce barriers to care, and increase awareness of how to seek mental health care. LACDMH has partnered with the Los Angeles Dodgers for several years to expand the reach of the campaign to the Major League Baseball team's audience and spread the WhyWeRise messages to the Dodgers' extensive Hispanic fan base-a key county demographic with attitudes toward mental illness that sometimes differ from those of other ethnic groups...

BACKGROUND: As youth participation in contact and overhead sports has increased in recent decades, so has the occurrence of injuries of the shoulder. Rotator cuff injury (RCI) is an infrequent shoulder pathology in pediatric patients and its description in the literature has been scarce. A greater understanding of RCI characteristics and treatment outcomes in children and adolescents would improve our understanding of this pathology and help to better guide clinical decision-making. HYPOTHESIS: To identify pediatric patients with magnetic resonance imaging-confirmed RCI treated at a single center to summarize injury characteristics, treatment, and outcomes...

Commotio cordis is one of the leading causes of sudden cardiac death in youth baseball. Currently, there are chest protector regulations regarding the prevention of Commotio cordis in baseball and lacrosse; however, they are not fully optimized. For the advancement of Commotio cordis safety, it is vital to include various age groups and a variety of impact angles in the testing process. This study employed finite element models and simulated Commotio cordis-inducing baseball collisions for different velocities, impact angles, and age groups...

PURPOSE: To evaluate the epidemiology of concussions in pediatric baseball and softball players. We hypothesized that head-to-ball injuries would be the most common cause of concussions. METHODS: The National Electronic Injury Surveillance System (NEISS) database was used to gather data. Concussions occurring during baseball and softball participation in pediatric patients (4-17 years old) from 2012 to 2021 was gathered. Concussion mechanisms were grouped into 5 categories: head-to-player, head-to-ball, head-to-surface (ground, walls, railings), head-to-bat, and unknown...

The following study employed an instrumental case study to investigate sport stakeholders' understandings of behavioural management strategies used in competitive youth baseball, including the identification of common strategies and interpretations of these as punishment or discipline. Twenty-one participants, from one competitive (AAA) all-boys baseball team, including three coaches, eleven baseball players, and seven parents, were recruited to participate in an individual semi-structured interview. Interviews ranged between 30 and 150 min, and data were analyzed using reflexive thematic analysis...

BACKGROUND: Pitch count recommendations are used to reduce injury risk in youth baseball pitchers and are based chiefly on expert opinion, with limited scientific support. Furthermore, they only account for pitches thrown against a hitter and do not include the total number of throws on the day a player pitched. Currently, counts are recorded manually. PURPOSE: To provide a method using a wearable sensor to quantify total throws per game that is compliant with Little League Baseball rules and regulations...

The harder the forearm flexor-pronator muscles (FPMs) relative to the ulnar collateral ligament (UCL), the less likely it is for UCL laxity to occur with repeated pitching. This study aimed to clarify what selective contraction of the forearm muscles makes FPMs harder relative to UCL. The study evaluated 20 elbows of male college students. Participants selectively contracted the forearm muscles in eight conditions under gravity stress. The medial elbow joint width and the strain ratio indicating tissue hardness of the UCL and FPMs during contraction were evaluated using an ultrasound system...

BACKGROUND: Arm injuries are commonly encountered in baseball as young athletes play into adulthood. The purpose of this study was to examine the incidence of arm injury and risk for surgery in adolescent baseball players followed over a 10-year period from scholastic, age-group, and travel baseball leagues through their highest level of competition. METHODS: A prospective study was conducted enrolling middle and high school baseball players in 2010-2012, then followed for 10 years or until retirement from competitive baseball...

BACKGROUND: Motion of the pelvis and trunk during baseball pitching is associated with increased upper extremity (UE) kinetics. Increased kinetics on the UE may lead to throwing-arm pain in youth pitchers. Limited biomechanical comparisons have been conducted on youth pitchers with and without throwing-arm pain to identify mechanical risk factors associated with pain. PURPOSE: To examine trunk and pelvic kinematics in youth baseball pitchers with and without UE pain...

We are in the middle of an epidemic involving pediatric and adolescent throwing athletes. Too many young athletes have elbow injuries, and it is unnerving how young surgical indications can present. Increased competition has led to increased demands before athletes have reached their full adult size. Evidence shows that higher ball velocity, higher shoulder external rotation angle, and higher arm speed are associated with increased medial elbow torque and elbow injury in this population. Pediatric and adolescent athletes should not try to throw as hard as possible, and weighted baseball training should be banned for youth athletes...

Baseball is an international sport with participation from tens of thousands of people worldwide. In the United States, the Prospect Development Pipeline (PDP) is a collaborative effort between Major League Baseball and USA Baseball to establish a developmental pipeline leading to the professional draft. Players participating in the PDP undergo comprehensive evaluations that measure athletic performance, speed-of-processing, visual function, and on-field talent. The present study evaluated data from 1352 elite junior male PDP participants (aged 14 to 21) who signed informed consent, collected between 2017 and 2020, to identify latent abilities and their association with player specialization...

This study of a randomized controlled trial aimed to clarify the effect of functional movement screen (FMS) training on the FMS score and the number of injuries in high-school baseball players. Accordingly, 71 high-school baseball players (age: 15-17 years) were randomized into an intervention group ( n = 37; FMS training 4 times per week for 12 weeks on the ground of each team) or a control group ( n = 34; team practice without limits). No significant differences were observed in terms of the participant characteristics of the two groups...

BACKGROUND: Sex differences in sports medicine are well documented. However, no studies to date have reviewed the rate at which sex is reported and analyzed in the athlete-specific orthopaedic sports medicine literature. PURPOSE: To determine the rates of reporting and analyzing patient sex in athlete-specific sports medicine literature. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: Articles published by the 3 journals of the AOSSM ( American Journal of Sports Medicine [ AJSM ], Orthopaedic Journal of Sports Medicine , and Sports Health: A Multidisciplinary Approach ) between 2017 and 2021 were considered for inclusion...

It is generally accepted that most of the energy transferred to the ball during a baseball pitch is generated in the trunk and lower extremities. Therefore, purpose of this study was to assess the energy flow through the lower extremities during a baseball pitch. It was hypothesised that the (stabilising) leading leg mainly transfers energy in a distal-to-proximal order as a kinetic chain while the (driving) trailing leg generates most energy, primarily at the hip. A joint power analysis was used to determine the rates of energy (power) transfer and generation in the ankles, knees, hips and lumbosacral joint (L5-S1) for 22 youth pitchers...
