Ultrasonographic Assessment

Background: Traction apophysitis of medial epicondyle (MEC) lesions and osteochondritis dissecans (OCD) of the capitellum are common elbow injuries in adolescent baseball players. However, the age-specific prevalence of these pathologies and their influence on elbow pain remain unknown. Purpose: To investigate the age-specific prevalence of each MEC lesion and capitellar OCD and to identify the incidence of elbow pain in each condition. Study Design: Descriptive epidemiology study. Methods: Study participants consisted of 4249 baseball players aged 6 to 17 years. A questionnaire was used to assess history of elbow pain, and morphological changes of the elbow joint were assessed using ultrasonography. Results: Regarding MEC lesions, fragmented (FG) and irregular (IR) lesions both reached their greatest respective prevalence at 11 to 12 years of age. After 14 years of age, IR decreased sharply, whereas FG was maintained at approximately 10%. Hypertrophic (HT) lesions increased sharply, reaching over 50% at 16 years of age, while there was a decrease in IR and FG lesions in the same age group. The prevalence of capitellar OCD remained the same (approximately 2%) throughout all ages except for in players aged 7 to 8 years (>7%). Players with MEC lesions had significantly greater prevalence of a history of elbow pain compared with those without (68.0% vs 39.1%) and were at a significantly greater risk for FG lesions (odds ratio [OR], 4.04; 95% CI, 3.16-5.22) compared with IR (OR, 3.22; 95% CI, 2.44-4.27) and HT lesions (OR, 2.03; 95% CI, 1.75-2.36). Players with capitellar OCD also had a significantly greater risk of a history of elbow pain (OR, 2.34; 95% CI, 1.40-4.11). Conclusion: Controlling the amount of practice and its intensity according to the condition of each player in the preadolescent and adolescent periods may be important in accelerating bony healing and decreasing preventable elbow pain in adulthood.

The Relationship

Background: Pitch velocity is associated with elbow injuries among skillful baseball players. However, the relationship between pitch velocity and throwing elbow injuries among youth players has not yet been clarified. Purpose: To investigate the influence of pitch velocity on medial elbow pain and medial epicondyle abnormality among youth baseball players. Study Design: Cohort study; Level of evidence, 3. Methods: The participants consisted of 256 elementary school players (mean age, 11 ± 1 years; range, 9-12 years). The medial aspect of the elbow was evaluated using ultrasound imaging. A questionnaire was used to investigate past or present pain in the elbow, background of the players (age, height, body mass index, and years of baseball experience), and playing environment (number of days of practice in a week, experience as a pitcher, and cryotherapy of the shoulder and elbow after practice). Positioning of the scapula, range of motion in shoulder internal/external rotations and hip internal rotation, angle of the straight-leg raise, and heel-to-buttock distance were measured. The pitch velocity was recorded using a pitch velocity radar gun. The relationship between these variables and the presence of medial epicondyle abnormality, as well as past or present elbow pain, were statistically analyzed. Results: A medial epicondyle abnormality was observed in 130 players (51%), elbow pain in the past in 65 players (25%), and elbow pain during the examination in 14 players (5%). Sixty-nine players (27%) experienced elbow pain either in the past or during examination. Abnormality of the medial epicondyle had a relationship with the pitch velocity (odds ratio [OR], 1.1 for increase of 1 km/h; 95% CI, 1.1-1.2; P < .0001) and the number of practice days in a week (OR, 1.8 for increase of the practice days; 95% CI, 1.4-2.5; P < .0001). Pitch velocity was also significantly related with past pain, present pain, and past and/or present pain of the elbow (OR [km/h], 1.1, 1.1, 1.1; 95% CI, 1.0-1.1, 1.0-1.2, 1.1-1.2; P < .0001, P = .002, P < .0001, respectively). Conclusion: Pitch velocity was significantly associated with abnormality of the medial epicondyle and elbow pain. A 10-km/h increase in pitch velocity would increase the risk of medial epicondyle abnormality and medial elbow pain by 3 times.

Background: Professional baseball pitchers are at high risk for tears of the ulnar collateral ligament (UCL) of the elbow, often requiring surgical reconstruction. Despite acceptable published return-to-play outcomes, multiple techniques and graft types have been described. Purpose: This study compares UCL reconstruction (UCLR) outcomes based on tunnel configuration and graft type. Study Design: Cohort study; Level of evidence, 3. Methods: After approval from our institutional review board and Major League Baseball (MLB), 566 professional baseball pitchers who underwent UCLR between 2010 and 2014 were identified and included. The following patient characteristics were analyzed: age, pitching role (starter vs reliever), level of play (MLB vs Minor League Baseball [MiLB]), and throwing side dominance. Surgical factors analyzed included reconstruction technique, graft type, and concomitant procedures. Primary outcome measures consisted of the ability to return to play at any level (RTP), ability to return to the same level of play (RSL), time to return, subsequent elbow injuries, and need for subsequent or revision elbow surgery. The effects of patient and surgical factors on outcomes were analyzed using multivariate linear and logistic regression modeling. Results: The RTP rate was 79.9%, and the RSL rate was 71.2%. Grafts used to reconstruct the UCL included the palmaris longus autograft (n = 361, 63.7%), the gracilis autograft (n = 135, 23.8%), and other grafts (n = 70, 12.5%). Surgical techniques utilized were the docking technique (n = 171, 30.2%), the modified Jobe technique (n = 290, 51.2%), and other techniques (n = 105, 18.6%). There were no significant differences in the time to RTP or RSL based on reconstruction technique or graft type. RTP rates were similar for the docking versus modified Jobe technique (80.1% vs 82.4%, respectively; P = .537) and for the 2 primary graft types (83.1% for palmaris longus vs 80.7% for gracilis; P = .596). The rate of subsequent elbow surgery was 10.5% for the docking technique versus 14.8% for the modified Jobe technique ( P = .203), and the rate of revision UCLR was 2.9% versus 6.2% for the docking versus modified Jobe technique, respectively ( P = .128). Significant trends toward an increasing use of the palmaris longus autograft ( P = .023) and the docking technique ( P = .006) were observed. MLB pitchers were more likely than MiLB pitchers to RTP ( P < .001) and RSL ( P < .001), but they required a longer time to return (mean difference, 35 days; P = .039) and had a higher likelihood of subsequent elbow (odds ratio [OR], 3.58 [95% CI, 2.06-6.23]; P < .001) and forearm injuries (OR, 5.70 [95% CI, 1.99-16.30]; P = .004) but not subsequent elbow surgery. No specific variables correlated with the rates of subsequent elbow surgery or revision UCLR in the multivariate analysis. The use of concomitant ulnar nerve transposition did not affect outcomes. Conclusion: Surgical outcomes in professional baseball players are not significantly influenced by UCLR technique or graft type. There was a high rate (46.3%) of subsequent throwing elbow injuries. MLB pitchers were more likely to RTP and RSL, but they had a higher frequency of subsequent elbow and forearm injuries than MiLB pitchers. Both the docking technique and the palmaris longus autograft are increasing in popularity among surgeons treating professional baseball players.

Background: Youth athletes are starting sports earlier and training harder. Intense, year-round demands are encouraging early sports specialization under the perception that it will improve the odds of future elite performance. Unfortunately, there is growing evidence that early specialization is associated with increased risk of injury and burnout. This is especially true of pediatric and adolescent baseball players. Purpose/Hypothesis: The purpose of this investigation was to analyze national injury trends of youth baseball players. We hypothesized that while the total number of baseball injuries diagnosed over the past decade would decrease, there would be an increase in adolescent elbow injuries seen nationally. A further hypothesis was that this trend would be significantly greater than other injuries to the upper extremity and major joints. Study Design: Descriptive epidemiology study. Methods: Injury data from the National Electronic Injury Surveillance System, a United States Consumer Product Safety Commission database, were analyzed between January 1, 2006, and December 31, 2016, for baseball players aged ≤18 years. Data were collected on the location of injury, diagnosis, and mechanism of injury. Results: Between 2006 and 2016, an estimated 665,133 baseball injuries occurred nationally. The mean age of the injured players was 11.5 years. The most common injuries diagnosed included contusions (26.8%), fractures (23.6%), and strains and sprains (18.7%). Among major joints, the ankle (25.6%) was most commonly injured, followed by the knee (21.3%), wrist (19.2%), elbow (17.7%), and shoulder (16.2%). The incidence of the ankle, knee, wrist, and shoulder injuries decreased over time, while only the incidence of elbow injuries increased. A linear regression analysis demonstrated that the increasing incidence of elbow injuries was statistically significant against the decreasing trend for all baseball injury diagnoses, as well as ankle, knee, wrist, hand, and finger injuries ( P < .05). Additionally, the only elbow injury mechanism that increased substantially over time was throwing. Conclusion: The current investigation found that while the incidence of baseball injuries sustained by youth players is decreasing, elbow pathology is becoming more prevalent and is more commonly being caused by throwing. Given that the majority of elbow injuries among adolescent baseball players are overuse injuries, these findings underscore the importance of developing strategies to continue to ensure the safety of these youth athletes.
