Study Design:
Review article.
Objective:
A review and update of the treatment of Hangman's fractures including the indications for both nonoperative and operative treatment of typical and atypical fractures.
Summary Of Background Data:
Hangman's fractures are the second most common fracture pattern of the C2 vertebrae following odontoid fractures. Many of the stable extension type I and II fractures can be treated with external immobilization, whereas the predominant flexion type IIa and III fractures require surgical stabilization.
Methods:
A review of the literature.
Results:
The clinical and radiographic outcomes of the treatment of Hangman's fractures lend a good overall prognosis when the correct diagnosis is made. The nonoperative treatment of stable type I and II fractures with external immobilization leads to excellent long-term outcomes as does the operative treatment of the unstable type IIa and III fractures.
Conclusions:
Hangman's fractures can be classified as stable (type I and most II) or unstable (type IIa and III) and the optimal treatment depends upon this distinction. Stable injuries do well with rigid immobilization and rarely require operative intervention. In contrast, unstable injuries do poorly if treated nonoperatively but do well with surgical intervention. When treating atypical Hangman's variants, great vigilance and close clinical observation is paramount if nonoperative treatment is indicated given the potential for neurological compression in this fracture pattern. Properly identifying and treating these injuries represents an opportunity for the spine surgeon to optimize patient outcomes.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
01:24Flail 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...
