AbstractRuptures of the pectoralis major (PM) tendon are rare but have increased in recent years, especially during fitness exercising, such as bench pressing. The pathomechanism is an eccentric load under pretension of the PM (falling onto the outstretched arm, injuries during ground combat, boxing and during downward movement when bench pressing). The rupture sequence starts from superior to inferior at the insertion site with initial rupture of the most inferior muscle parts, followed by the sternal part and the clavicular part. Most classifications are based on rupture location, extent and time of injury. In addition to clinical presentation and sonography, magnetic resonance imaging is now established as the gold standard in diagnosing PM pathologies. Surgical management is indicated for all lateral PM ruptures with relevant strength deficits. Treatment in the acute interval (<3 weeks) is the primary goal; however, even in chronic cases or after failed conservative management a secondary operative approach enables notable clinical improvement. Conservative therapy mostly affects patients who have muscular injuries close to the anatomic origin and smaller partial tears. Surgical management aims for anatomic reconstruction of the PM unit with restoration of the original tension to enable optimal strength transmission. Surgical refixation or reconstruction (with autograft/allograft) of acute and chronic PM ruptures shows excellent clinical results with high patient satisfaction. Latissimus dorsi (LD) and teres major (TM) tendon ruptures are rare injuries but can lead to significant impairments in high-performance athletes. In contrast to PM ruptures, LD and TM injuries are primarily treated conservatively with very satisfactory results.
