Anterior cutaneous nerve entrapment syndrome (ACNES) and thoracic radiculopathy are rare forms of abdominal pain. Therefore, we herein report an older man with chronic right lower abdominal pain from coexisting ACNES and thoracic radiculopathy, probably triggered by asymptomatic thoracic compression fractures and significant weight loss. The diagnosis was confirmed based on a positive Carnett's sign and immediate pain relief after the diagnostic lidocaine injection. Imaging revealed a T12 compression fracture with narrowing of the right T11/12 intervertebral foramen. This case highlights the need to consider ACNES and spinal pathology in older patients with unexplained abdominal pain in the context of frailty and postural changes.

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
