The pectoralis major is a very powerful muscle that forms the chest prominence and. It moves the shoulder forward and across your chest. It is best known as the muscle that you develop with the bench press exercise in gymnasium. The pectoralis major attaches to the humerus bone and is divided into two parts. The upper part is known as the "clavicular head" and the lower part the "sternal head," based on their origins from the clavicle and sternal bones, respectively. Ruptures of the pectoralis major muscle are becoming more common due to the increase in power sports weight training.
A About 25-year-old male presented to Out Patient Department with bruising and swelling over the anterior wall of left axilla. The patient was engineer and amateur weight lifter. Clinically, the swelling was tender, and movements of left arm were restricted. Muscle tear was suspected and hence magnetic resonance imaging (MRI) was advised which showed tear of tendon of pectoralis major muscle. The patient was treated surgically and has got full range of movements of the arm.
MRI is the mainstay for diagnosing pectoralis major tear. The earlier a repair is performed the easier the surgery and the better the outcome of surgery.
胸大肌是一块非常有力的肌肉,形成胸部隆起。它使肩部向前并越过胸部移动。它最为人所知的是在健身房进行卧推练习时锻炼的肌肉。胸大肌附着于肱骨,分为两部分。根据其分别起源于锁骨和胸骨,上部称为“锁骨部”,下部称为“胸骨部”。由于力量型运动和重量训练的增加,胸大肌断裂变得越来越常见。
一名约25岁男性因左腋窝前壁瘀伤和肿胀就诊于门诊部。该患者是一名工程师兼业余举重运动员。临床上,肿胀处压痛,左臂活动受限。怀疑有肌肉撕裂,因此建议进行磁共振成像(MRI)检查,结果显示胸大肌腱撕裂。该患者接受了手术治疗,目前手臂活动已完全恢复。
MRI是诊断胸大肌撕裂的主要手段。修复手术进行得越早,手术越容易,手术效果越好。
