Background:
Alcohol as a cofactor in interpersonal violence (IPV) has been established by studies from a number of countries. This study aimed to determine if alcohol was a cofactor in the incidence or severity of mandible fracture.
Methods:
A prospective study of mandible fracture patients presenting for oral maxillofacial review over 16 months was completed. Injury severity was assessed utilizing the Mandible Injury Severity Score (MISS).
Results:
A total of 252 facial trauma cases presented to our tertiary referral centre, 83 with fractures of the mandible. The majority of presentations were secondary to IPV (n = 54, 65.06%), 49 (90.74%) of these cases involved alcohol. Overall, alcohol was involved in 63.85% of cases (n = 53). The relative risk of requiring surgical intervention with alcohol involvement was 2.68 (CI = 1.11-9.47). Alcohol significantly increased facial fracture severity for MISS: alcohol (n = 53) 13.07 ± 5.01, no alcohol (n = 30) 11.03 ± 4.87 (p < 0.05). IPV also increased facial fracture severity for MISS: IPV (n = 54) 13.09 ± 4.90, non-IPV (n = 29) 11.00 ± 4.81 (p < 0.05). The angle of the mandible was most commonly fractured (40.5% of cases).
Conclusions:
Mandible fracture patients, whose injury is a result of IPV, have more severe fractures and a higher likelihood of requiring surgery if alcohol is involved. This correlates to a higher surgical workload, economic and social burden to the community. Primary alcohol and IPV prevention strategies will play an important role in reducing mandible fracture.

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 procedure...

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...

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
