Case: A 26-year-old amateur baseball player without prodromal arm pain sustained a thrower's fracture of the humerus on a warm-up throw performed with submaximal effort. The fracture occurred during the first throwing session following a 6-week layoff. The patient was treated nonoperatively and made a full recovery, but he elected to not return to throwing sports.

Conclusion: Because of the lack of risk factors in this case, we suggest that time off or irregularity in throwing may play a greater role in a thrower's fracture than previously established. Recreational throwers should undergo appropriate preseason training before returning to throwing.

Article Synopsis
  • - A thrower's fracture is a specific type of arm fracture in the humerus that typically happens during the throwing motion, marked by an audible pop and severe pain.
  • - A 25-year-old semi-professional pitcher faced a severe arm injury with high compartment pressures and required emergency surgery for fasciotomy after experiencing these symptoms.
  • - This report highlights the importance of monitoring for compartment syndrome in thrower's fractures, as it poses a significant risk of additional complications.

Description Atraumatic ball thrower's humerus fracture is an uncommon, and poorly understood injury pattern. The majority of these cases are seen in untrained and younger individuals. A missed diagnosis could severely impact a patient's quality of life, as management is operative in most cases.

Background: The etiology and pathogenesis of osteochondritis dissecans (OCDs) lesions remain controversial.

Methods: This review presents the recent evolution about the healing, imaging, pathogenesis, and how to treat OCD of the capitellum in overhead athletes.

Results: Compressive and shear forces to the growing capitellum can cause subchondral separation, leading to OCD, composed of 3 layers: articular fragment, gap, and underlying bone.

Article Synopsis
  • Overhead throwing in sports like baseball can lead to specific shoulder and elbow injuries, including conditions like GIRD, Bennett lesions, and SLAP tears, primarily due to repetitive stress and movement patterns.
  • GIRD is characterized by a reduction in internal rotation while external rotation increases, and Bennett lesions are caused by chronic tension leading to ossification of ligaments in the shoulder.
  • Elbow injuries often affect the ulnar collateral ligament (UCL) and may include medial epicondylitis and conditions like posteromedial impingement, which are exacerbated by the high valgus stress experienced during throwing motions.
