Objectives:
To determine which in-hospital complications after the operative treatment of hip fractures are associated with increased in-patient, 30-day, and 1-year mortality.
Design:
Retrospective study.
Setting:
A single academic medical center and a Level 1 Trauma Center.
Patient Selection Criteria:
All patients who were operatively treated for hip fractures (Orthopaedic Trauma Association/AO 31A, 31B and Vancouver A, B, and C periprosthetic fractures) at a single center between October, 2014, and June, 2023.
Outcome Measures And Comparisons:
Occurrence of an in-hospital complication was recorded. Cohorts were based on mortality time points (during admission, 30 days, and 1 year) and compared with patients who were alive at those time points to determine which in-hospital complications were most associated with mortality. Correlation analysis was performed between patients who died and those who were alive at each time point.
Results:
A total of 3134 patients (average age of 79.6 years, range 18-104 years and 66.6% women) met inclusion for this study. The overall mortality rate during admission, 30 days, and 1 year was found to be 1.6%, 3.9%, and 11.1%, respectively. Sepsis was the complication most associated with increased in-hospital mortality (odds ratio [OR] 7.79, 95% confidence interval [CI], 3.22-18.82, P < 0.001) compared with other in-hospital complications. Compared with other in-hospital complications, stroke was the complication most associated with 30-day mortality (OR 7.95, 95% CI, 1.82-34.68, P < 0.001). Myocardial infarction was the complication most associated with 1-year mortality (OR 2.86, 95% CI, 1.21-6.77, P = 0.017) compared with other in-hospital complications.
Conclusions:
Postoperative sepsis, stroke, and myocardial infraction were the 3 complications most associated with mortality during admission, 30-day mortality, and 1-year mortality, respectively, during the operative treatment of hip fractures.
Level Of Evidence:
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

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...
