The pectoralis major (PM) muscle is the largest and most superior muscle of the anterior chest wall. The PM plays an important role in flexion, adduction, and internal rotation of the arm. The pectoralis major's size, strength, and anatomical location make it an excellent candidate in transfer surgeries due to its ability to restore balancing forces that may be lost in scapular winging and subscapularis tears. Each of these injuries and pathologies involves the PM muscle in some way, and careful consideration of its anatomy and physiology is necessary. This review article aims to provide a comprehensive overview of the anatomy, physiology, and surgical considerations of the pectoralis muscle with a specific focus on the surgical techniques involving the muscle.
A comprehensive literature search using a combination of the following terms: pectoralis major, rupture, transfer, chronic subscapularis tear, pectoralis surgery, anatomy, scapular winging, and long thoracic nerve anatomy. There were no limitations with regards to article type or publishing date, but article language was limited to only English.
The pectoralis muscle is an important muscle when it comes to function of the upper extremity primarily or through transfer procedure. Injuries and impairments of the pectoralis major or other muscles of the upper extremity can significantly impact an individual's quality of life, limiting their ability to perform activities of daily living. A thorough understanding of anatomical, functional, and surgical purposes of the pectoralis muscle is crucial for achieving optimal outcomes and avoiding complications.
胸大肌是前胸壁最大且最靠上的肌肉。胸大肌在手臂的屈曲、内收和内旋中起重要作用。胸大肌的大小、力量和解剖位置使其成为转位手术的理想选择，因为它能够恢复在肩胛翼状畸形和肩胛下肌撕裂中可能丧失的平衡力量。这些损伤和病症均以某种方式累及胸大肌，因此有必要仔细考虑其解剖结构和生理功能。这篇综述文章旨在全面概述胸大肌的解剖学、生理学及手术注意事项，特别关注涉及该肌肉的手术技术。
使用以下术语组合进行全面的文献检索：胸大肌、断裂、转位、慢性肩胛下肌撕裂、胸大肌手术、解剖学、肩胛翼状畸形及胸长神经解剖学。对文章类型或发表日期没有限制，但文章语言仅限于英语。
胸大肌在主要或通过转位手术实现上肢功能方面是一块重要的肌肉。胸大肌或上肢其他肌肉的损伤和功能障碍会显著影响个体的生活质量，限制其进行日常生活活动的能力。全面了解胸大肌的解剖学、功能及手术目的对于获得最佳治疗效果和避免并发症至关重要。
