Abstract
Pectoralis major muscle tendon ruptures associated with physical activity or effort are no longer uncommon in the medical literature. Treatment has also evolved significantly in the last 20 years. However, simultaneous bilateral rupture has only been described in a few cases. This article reports three cases with simultaneous bilateral rupture and describes the examinations and treatment performed. Bilateral lesions, although infrequent, also require early diagnosis and treatment in the acute phase. The chronic phase requires tendon grafting for full correction and a slow rehabilitation process.
