Background:
High-energy pelvic ring injuries (PRIs) are increasingly observed in the elderly, a population with unique physiological vulnerabilities. However, outcome data in patients aged ≥75 years remain scarce.
Methods:
In this retrospective cohort study, 331 patients with high-energy PRIs over 11 years at a Level 1 trauma centre were analysed. Using 1:1 propensity score matching, outcomes in patients aged ≥75 years were compared with younger patients (<75), adjusting for injury severity and baseline characteristics.
Results:
Twenty-eight patients aged ≥75 were matched to 28 younger counterparts. Mortality was significantly higher in the elderly group (32 % vs. 7 %, p = 0.006), despite comparable injury severity scores. Elderly patients were less likely to be admitted to the intensive care unit (ICU) (29 % vs. 64 %, p = 0.007), with shorter ICU stays, though total hospital length of stay did not differ. Fracture morphology and mechanisms of injury also varied by age, with older adults showing simpler patterns but higher mortality.
Conclusion:
Elderly patients with high-energy PRIs exhibit distinct injury mechanisms and patterns, experience a five-fold higher mortality despite less frequent ICU admission and matched injury severity. These findings highlight the urgent need for age-adapted trauma protocols and proactive perioperative strategies in managing pelvic trauma in the elderly.

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...
01:09Changes 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...

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...
