The Effect of Bone Minerals Density on Mortality of Elderly Patients Applying with a Proximal Fracture of the Femur.

PURPOSE OF THE STUDY This study aimed to evaluate the risk of mortality in elderly hip fracture patients within one year after surgery, and to compare it with DXA values and to evaluate the predictive value of DXA values.

MATERIAL AND METHODS This is a prospective study including data from 160 elderly hip fracture patients treated in our hospital. The patient data included the following; DXA values of spine, neck, intertrochanteric, total and ward's T-scores, age, blood values (preoperative CRP (mg/dl), CRP/Albumin ratio, albumin (g/dl), sex, creatine value (mg/dL), American Society of Anesthesiologists (ASA) scores, and type of surgery.

RESULTS The risk of mortality was 5.06 times higher in patients with neck DXA values ≤-2.2 cut-off value (DXA values of neck odds ratio (OR) = 5.06, 95%CI: 544-.723, P: 0.02). There was a statistically significant difference between the DXA values of spine, intertrochanteric, wards, creatine, and albumin values between the groups (respectively p=0.002, p=0.005, p=0.01, p=0.003, and p=0.01).

CONCLUSIONS Biomarkers to assess mortality one year postoperatively in elderly patients undergoing surgery for hip fracture are lacking. The mortality rate was found to be 5.06 times higher in patients with DXA values of neck ≤-2.2 cut-off. Severe osteoporosis is a disease with high mortality. The initiation of osteoporosis treatment should be started earlier.
