Ulnar collateral ligament injury and osteochondritis dissecans in adolescent baseball pitcher

Adolescent baseball pitchers are at an increased risk of developing elbow injuries, including ulnar collateral ligament (UCL) injury and osteochondritis dissecans (OCD). Both conditions can occur due to the repetitive stress placed on the elbow joint during pitching motions. Ulnar collateral ligament injury: The UCL is a key stabilizing ligament on the inner side of the elbow joint. During the pitching motion, valgus and external rotation stress can cause excessive force on the UCL, leading to microtears, inflammation, or even a complete tear. Symptoms of a UCL injury may include pain on the inner side of the elbow, swelling, instability, and a decrease in pitching velocity or accuracy. Osteochondritis dissecans: OCD is a condition that affects the joints, including the elbow joint. It occurs when a small segment of bone begins to separate from its surrounding region due to a lack of blood supply. This separated bone and the adjacent cartilage can either remain in place or partially or completely detach, causing pain and potentially limiting the range of motion. OCD in adolescent pitchers is often linked to the repetitive stress placed on the elbow joint during the pitching motion. To prevent these injuries, it is essential for adolescent pitchers to practice proper pitching mechanics, maintain a balanced training regimen focusing on strength and flexibility, and adhere to guidelines on pitch count and rest periods. Early diagnosis and appropriate treatment are crucial in managing these conditions and ensuring a safe return to play. 청소년 야구 선수들의 팔꿈치 손상은 주로 투구 동작 중 발생하는 외전 - 외회전 스트레스와 관련이 있습니다. 이러한 스트레스가 팔꿈치 관절에 과도한 힘이 반복적으로 가해지면 팔꿈치 관절을 쭉펴는 과정에서 안쪽 내측 측부 인대 구조에 긴장이 발생합니다. 이러한 긴장은 시간이 지남에 따라 인대 손상과 관절 연골의 손상이 발생하는데 이를 내측 측부 인대 손상과 박리성 골연골염이라 합니다.
