Pectoralis Major Rupture in a 15-year-old Teenager: Case Report.

Rupture of the pectoralis major muscle is extremely rare in adolescents. The current literature contains only 5 reports of this condition in patients under 20 years old, with 2 reports in subjects under 16. In the present article, we report the case of a 15-year-old volleyball player who suffered a traumatic rupture of the pectoralis major in a match during the serve movement. After excluding endocrinological abnormalities as a cause of tendon weakening, the patient underwent surgical treatment due to muscle retraction, strength deficit, high demand, and esthetic concerns. Early diagnosis is crucial to successful outcomes, and the surgical intervention enabled early rehabilitation and a provided a higher likelihood of return to high-level competitive sports.
