AI Article Synopsis
- The study investigates elbow injuries (MEC lesions and capitellar OCD) in adolescent baseball players aged 6-17 to determine their prevalence and link to elbow pain.
- The findings reveal that certain MEC lesions peak in prevalence at ages 11-12, while capitellar OCD remains relatively stable, with some increases seen in younger players.
- Players with MEC lesions and capitellar OCD show significantly higher rates of elbow pain, suggesting a need for better management of practice intensity to promote healing.
Article Abstract
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.

Background: There are various options of tendon transfer according to the different types of irreparable rotator cuff tears (IRCTs). However, there were no clear treatment options for the IRCTs involving the anterior, superior and posterior rotator cuff tears (global IRCTs). Latissimus dorsi and teres major (LDTM) could be transferred anteriorly or posteriorly in global IRCTs.

Background: The efficacy of extracorporeal shockwave therapy (ESWT) for treating shoulder calcific tendinitis can be influenced by various prognostic factors. This study aimed to identify prognostic factors associated with the failure of ESWT for symptom relief and to evaluate the predictive capability of the eXtreme Gradient Boosting (XGBoost) algorithm of artificial intelligence techniques in this context.
Methods: This retrospective study enrolled patients with persistent shoulder pain attributed to calcific tendinitis who underwent ESWT after failed conservative treatment between January 1998 and December 2022.

Radial nerve compression at the arcade of Frohse is a rare but significant condition that typically presents with pain primarily after exertion and at night on the dorsal side of the forearm, more distally than tennis elbow pain, and weakness of the wrist extensors and the long fingers and thumb extensors. Traditional treatment often involves open surgery, resulting in significant scarring. This study introduces a novel percutaneous radial nerve release technique under complete ultrasound guidance and highlights its efficacy and safety.

Background: Our understanding of osteoarthritis (OA) has evolved from a degenerative disease to one in which low-grade, chronic inflammation plays a central role. In addition, evidence suggests that OA is accompanied by both peripheral and central nervous system sensitization that can cause pain. It has been demonstrated that transcutaneous vagus nerve stimulation (tVNS) can relieve pain, inflammation, and central sensitization in other conditions including fibromyalgia, pelvic pain, and headaches.

Background: Glenoid bone loss presents a complex challenge in the management of patients with glenohumeral osteoarthritis (GHOA) undergoing Reverse Shoulder Arthroplasty (RSA). Eccentric reaming and bone grafting have been utilized to address this issue but are associated with their own set of challenges. This study explores the effectiveness of augmented glenoid baseplate RSA in addressing glenoid bone loss.
