Introduction:
Lower extremity fractures are very common in victims of falls. These fractures are usually associated with other bodily injuries and can lead to permanent disability if appropriate management is not provided. The aim of this study was to evaluate the incidence and outcomes of associated injuries in victims of falls with lower extremity fractures.
Methods:
This is a retrospective review (1995-2006) of all fall-related trauma patients evaluated at our Level I trauma center. Injuries were categorized as: isolated femur fractures (FF), isolated tibia fractures (TF), and both femur and tibia fractures (FTF). Data were analyzed for differences in patterns of injury, associated fractures and injuries, and mortality and morbidity according to age groups within patients with minor body injuries expressed by Abbreviated Injury Score (AIS) < 3.
Results:
Three hundred and thirty-two patients (64.8 %) had FF, 164 patients (32 %) had TF, and 16 patients (3.2 %) presented with FTF. The incidence of severe trauma was 9.4 % (Injury Severity Score, ISS > 25). A higher incidence of ISS > 25 was observed in patients with FF. Increased mortality was observed in the elderly group, especially in patients with an isolated femur fracture.
Conclusion:
Patients with a combination of femur and tibia fractures have a significantly higher risk of associated injuries compared to patients with either a femur or a tibia fracture. Elderly patients (≥65 years of age) have higher morbidity and mortality compared to younger patients after falls. Clinicians evaluating these patients should be aware of these injury patterns. Further studies assessing the impact of age and pattern of injury in patients following falls are warranted.

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...

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...
