[Surgical treatment of chronic pectoralis major rupture]

Simultaneous repair of bilateral pectoralis major tendons: A case report

BACKGROUND

Injuries to the pectoralis major are infrequent, with only a few hundred cases currently recorded in the literature.

CASE SUMMARY

We report a case of a patient who sustained bilateral pectoralis major tendon ruptures. While other cases of bilateral pectoralis major tears have been reported in the literature, the operative management in this report differs. Due to delayed presentation of the patient right and left pectoralis major repairs were performed simultaneously.

CONCLUSION

Patients with delayed presentation of bilateral pectoralis major tendon ruptures can undergo simultaneous repair of both tendon with a good postoperative outcome and high patient satisfaction.

[Acute rupture of the pectoralis major muscle at the musculotendinous junction : Case report of a rare injury and literature review]

Die Pectoralis-major-Ruptur (PMR) ist eine seltene Verletzung, die v. a. beim Kraftsport aufritt. Vorgestellt wird der Fall eines 31-jährigen Profibasketballspielers, der sich beim Bankdrücken eine Komplettruptur am muskulotendinösen Übergang des M. pectoralis major (PM) zugezogen hatte. Drei Wochen nach dem erlittenen Trauma erfolgte bei persistierenden Schmerzen und Kraftdefizit die Refixation des PM. Drei Monate postoperativ konnte der Patient bei vollem Bewegungsumfang schmerzfrei in den Basketballsport zurückkehren. Die Verletzungsentität wird vor dem Hintergrund der aktuellen Literatur diskutiert und das operative Vorgehen im Detail dargestellt.

[Rupture of the pectoralis major tendon and other extra-articular tendons of the shoulder : Recognition and treatment]

Ruptures 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.
