Abstract:
A 71-year-old multi-morbid, paraplegic male with five pressure ulcers and a left-sided open trochanter fracture with chronic osteomyelitis was admitted to hospital. His condition required exarticulation of the left hip joint. A radical wound revision and a pedicled lower extremity fillet flap reconstruction of the defect was performed. The patient made uneventful recovery to normal activity within six weeks and had a stable result after one year follow-up. The case is a reminder of the importance of early intervention and preventive management of pressure ulcers and elaborates the benefits of interdisciplinary team efforts in the treatment of advanced ulcers.

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...
