Summary
Repetitive overhead throwing causes stress on young athletes' shoulder and elbow joints, potentially leading to injury. Prevention focuses on optimizing mechanics, core strength, and range of motion to avoid overuse and damage.
Area of Science:
- Sports Medicine
- Orthopedics
- Pediatric Sports Injury
Background:
- Overhead throwing activities place significant mechanical stress on the shoulder and elbow.
- Young athletes are susceptible to developmental anatomic changes and asymptomatic joint pathology due to repetitive stress.
- Overuse and poor biomechanics can lead to disabling injuries in pitchers.
Purpose of the Study:
- To highlight the risks of repetitive overhead throwing in young athletes.
- To emphasize the prevalence of asymptomatic pathology and its progression to injury.
- To underscore the importance of identifying and preventing overuse in youth baseball pitchers.
Main Methods:
- Review of biomechanical principles in overhead throwing.
- Analysis of the relationship between pitching mechanics and joint stress.
- Discussion of factors contributing to overuse injuries in young throwers.
Main Results:
- Asymptomatic shoulder and elbow joint pathology is common in young throwers.
- Inadequate coordination of motion segments during pitching delivery contributes to structural damage.
- Overuse is a primary factor in the development of disabling injuries.
Conclusions:
- Identifying and preventing overuse is critical for injury avoidance in young pitchers.
- Injury prevention and rehabilitation strategies should focus on biomechanics, core strength, scapular stability, and joint mobility.
- Optimizing pitching mechanics and physical conditioning is essential for long-term joint health.

Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

Muscles that Move the Forearm
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...
