Abstract:
Medial fractures are the least common type of clavicular fracture (2-10%). The patient is a 29-year-old gynaecology resident with hyper-laxity and sternoclavicular instability. The latter had been surgically stabilized with Dacron((R)) tape, which eroded the bone causing an usura. Acute right shoulder pain occurred 10 years later. CT revealed medial clavicular stress fracture. After 4 weeks of conservative management, internal fixation followed. Five months postoperatively the patient performed all activities without pain. In this patient the weakened medial clavicle due to usura clearly played a role in both the site and nature of the fracture. Furthermore, CT is essential in arriving at the correct diagnosis.

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...

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
