Little League Shoulder

Abstract Objective Ultrasound (US) is an established imaging modality in adult sports medicine but is not commonly used in the diagnosis of pediatric sports conditions, such as Little League shoulder (LLS). This study was conducted to determine the reliability of US measurement of width of the physis at the proximal humerus in diagnosed LLS and to compare US to radiography (RA) in detecting a difference between the affected (dominant) (A) and unaffected (U) shoulders. Materials and Methods Ten male baseball players diagnosed with LLS were enrolled in the study. US images of the proximal humeral physis at the greater tuberosity of both shoulders were obtained by an US-trained sports medicine physician, and the physeal width was measured. Blinded to prior measurements, a separate physician performed measurements on the stored US images. Measurements were compared with RA on the anteroposterior (AP) view for both A and U at the time of the initial visit and for A at follow-up. Results The physeal width (mm) at A and U at the initial visit averaged 5.94 ± 1.69 and 4.36 ± 1.20 respectively on RA, and 4.15 ± 1.12 and 3.40 ± 0.85 on US. Median difference of averaged US measurements between A and U at initial evaluation was 0.75 mm (p = 0.00016). A linear model showed US measurements to be predictive of RA on A (R2 = 0.51) and U (R2 = 0.48). Conclusion US was able to reliably measure the width of the proximal humeral physis and detect a difference between A and U. US correlated well with RA (standard for LLS). US should be considered by the US-trained physician for the diagnosis of LLS.

Closed Kinetic Chain

Context:Many studies have explored closed kinetic chain (CKC) shoulder exercises (SEs) with a sling because they are safer and more effective than open-chain exercises, especially in early stages of treatment. However, the application of CKC SE in youth baseball players has rarely been attempted, although teenage baseball players also experience shoulder pain.Objective:To investigate the effects of CKC SE on the peak torque of shoulder internal rotation (IR) and external rotation (ER) in youth baseball players.Design:Single-group pretest, posttest.Setting:Biomechanics laboratory.Participants:23 Little League Baseball players with subacromial impingement syndrome.Interventions:The CKC SE with a sling was CKC shoulder-flexion exercise, extension exercise, IR exercise, and ER exercise. This exercise regimen was conducted 2 or 3 times/wk for 8 wk.Main Outcome Measures:The peak torque of shoulder IR and ER was measured using an isokinetic dynamometer. Concentric shoulder rotation was performed, with 5 repetitions at an angular velocity of 60°/s and 15 at 180°/s.Results:The IR and ER peak torque significantly increased at each angular velocity after the exercise program. In particular, the increase in IR and ER peak torque values was statistically significant at an angular velocity of 180°/s.Conclusions:CKC SE was effective in increasing shoulder IR and ER strength, demonstrating its potential benefits in the prevention and treatment of shoulder injury. In addition, increased IR peak torque appears to improve throwing velocity in baseball players.

Patterns Of Injury

Objectives. To determine the patterns of injury in youth baseball and apply the data to estimate the value of proposed safety equipment. Design. Prospective population-based injury survey. Participants. 2861 Little League baseball players (ages 7 to 18) for 140 932 player-hours. Measurements. An injury was included in the data only if it was serious enough to require medical/dental care, caused missing a game, or disallowed playing a certain position. The injuries were subdivided into acute or overuse. The acute injuries were classified as either catastrophic, severe, or minor. Injuries were categorized according to mechanism, area injured, and whether the player was on offense or defense. Results. There were 81 total injuries, of which 66 (81%) were acute and 15 (19%) were overuse. Of the acute injuries, 11 were severe and 55 were minor. The overall injury rate was .057 injuries per 100 player-hours. The severe injury rate was .008 injuries per 100 player-hours, of which 46% were ball-related injuries and 27% were collisions. The most frequent mechanism of injury was being hit by the ball, which represented 62% of the acute injuries. Of the 41 ball-related injuries, 28 (68%) occurred to players on defense. Of the 18 ball-related facial injuries, 16 occurred to players on defense. Conclusions. 1) Little League baseball is a safe activity with a low injury rate and a particularly low rate of severe injury; 2) impact by the ball causes more than half the acute injuries, thus safety interventions should be directed towards decreasing these injuries, especially on defense; 3) facemasks on batters can safely eliminate facial injuries to offensive players, but would only moderately reduce the incidence of ball-related facial injuries as most of these injuries are sustained by defensive players.

Little League Shoulder

Background: Little League shoulder (LLS) is an overuse injury characterized by throwing-related pain that commonly presents in adolescent male athletes. Investigations into the optimal duration of rest from throwing and protocols for graduated return to sports (RTS) are lacking. Purpose: To summarize the current literature with respect to the diagnosis, management, RTS, and return to throwing for LLS. Design: Systematic review; Level of evidence, 4. Methods: The databases EMBASE, MEDLINE, and PubMed were searched between inception and April 22, 2020. References of retrieved records were reviewed for potentially eligible studies. English-language studies that reported the diagnosis and/or management of LLS in children or adolescents were included. Studies of animals or cadavers, review articles, and non—peer reviewed records were excluded. Data were summarized narratively using descriptive statistics. Results: Overall, 23 studies (21 level 4 studies, 2 level 3 studies) met the criteria for a total of 266 participants with a weighted mean age of 12.8 years (range, 7.4-17 years). Treatment recommendations evolved from prolonged rest and complete cessation of throwing to shorter periods of rest and graduated RTS. Less than half (11/23) of studies reported specific criteria to RTS; 1 case report discussed a coaching strategy to resume throwing, and 1 case report discussed a regimented throwing program. The proportion of participants returning to any sport participation was 94.0% (n = 157/167). The proportion returning to their preinjury level of sport was 92.5% (n = 123/133). Upon RTS, 18.7% (n = 35/187) of participants experienced a recurrence of symptoms. Premature closure of the epiphysis was reported in 1 participant. Conclusion: Young athletes with LLS may return to play after a period of rest, and a high proportion return to their preinjury level of sport. Further prospective studies are warranted to develop evidence-based, graduated RTS protocols and to better capture any long-term sequelae of the condition.
