Insights
Older patients (80+) undergoing hip fracture surgery face higher mortality risks. Higher ASA scores (3-4) and longer hospital stays also correlate with increased mortality after partial hip replacement.
Area of Science:
- Geriatric Medicine
- Orthopedic Surgery
- Public Health
Background:
- Hip fractures are a growing concern due to global population aging.
- Partial hip prosthesis is a common surgical intervention for hip fractures in elderly patients.
Purpose of the Study:
- To examine the relationship between mortality and morbidity in patients aged 65+ undergoing partial hip prosthesis for hip fractures.
- Identify key factors influencing mortality post-hip fracture surgery.
Main Methods:
- Retrospective analysis of 443 patients (≥65 years) who had partial hip prosthesis surgery between 2007-2014.
- Investigated pre-operative factors including age, gender, fracture type, comorbidities, ASA scores, and time to mortality.
Main Results:
- Mortality within one year was 36.57% (162 patients).
- Patients aged 80 and above showed a significant increase in mortality.
- Higher mortality rates were observed in patients with ASA scores of 3-4 compared to ASA 1-2.
- Longer hospital stays were associated with higher one-year mortality.
Conclusions:
- Age (80+), high ASA scores (3-4), and prolonged hospital stay are significant predictors of mortality after partial hip replacement for hip fractures.
- Time to surgery did not show a statistically significant relationship with mortality.
Background & Aims:
The number of hip fracture surgeries exhibit an increasing trend due to the aging of the world's population and it is expected to become a serious public health problem in the future. This study aimed to investigate the relationship between mortality and morbidity in patients aged 65 years or older who underwent partial hip prosthesis due to hip fracture.
Methods:
Four-hundred and forty-three patients aged 65 and above who underwent partial hip prosthesis for fractured hips between 2007 and 2014 were retrospectively investigated. The age before surgery, gender, type of fracture, additional diseases, ASA scores of the patients and time to mortality were investigated in addition to the factors that affect mortality.
Results:
Of the 443 patients in the study, 167 were males and 276 were females, with an average age of 80.5 ± 7.2 and 81.1 ± 7.0 years, respectively. One hundred and sixty-two (36.57%) of these patients died within the first year. When the patients were investigated according to age groups, there was a significant relationship between mortality after surgery and patients aged 80 years and above. No statistically significant relationship was found between the time to surgery and mortality. When compared in terms of ASA scores, it was concluded mortality in ASA 3 and 4 groups was significantly higher than ASA 1 and 2 groups (p < 0.001). When hospital stay and one-year mortality rates were compared, it was seen that the length of hospital stay of the patients who died in the first year was significantly higher.
Conclusions:
In patients who underwent partial hip replacement after hip fracture, there was a significant relationship between mortality, long hospital stay, patients with an ASA score of 3-4, and patients aged 80 years and above, whereas no relationship was detected with time to surgery.

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...
