Case:
We present a case of a patient who sustained a rhomboid major origin tear with subsequent seroma formation. The rhomboid major origin was reattached using an Achilles tendon allograft to supplement the repair, and the seroma wall was excised. We were able to alleviate the patient's pain and improve his shoulder function. We present our surgical technique.
Conclusion:
Scapular winging is most often attributed to neurogenic causes, but the goal of this case report is to help orthopaedic surgeons realize that scapular winging is not only a nerve issue but can result from an acute muscle tear.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
