Abstract
Background
Several studies in older patients with femoral neck fracture found that preoperative
anemia and malnutrition were associated with higher mortality and poorer physical
function. Therefore, we compared nutritional status, Hb level, and renal function
in women with femoral neck fracture and women of the same age with osteoarthritis
of the hip joint.
Methods
We enrolled 257 women aged 70 years and older who suffered femoral neck fracture (F
group) or who were scheduled to undergo total hip arthroplasty for osteoarthritis
of the hip joint (OA group). The F and OA groups were further divided into 2 groups
on the basis of age, ie, 74 years old and younger (F70 and OA70) and 75 years old
and older (F75 and OA75). To assess whether patients had undernutrition, mortality
risk, anemia, and renal dysfunction, we assessed Geriatric Nutritional Risk Index
(GNRI), Hb, and eGFR.
Results
We found a significant difference in the mean Hb levels and GNRI scores between the
F75 and OA75 and F70 and OA70. Moreover, we found a moderate correlation between Hb
level and GNRI score in the F75 and OA75. With respect to the GNRI category, the percentage
of patients at moderate or major risk was 42.1% in the F70 group and 57.6% in the
F75 group but only 1.9% in the OA70 group and 4.3% in the OA75 group.
Conclusion
We found that women with femoral neck fracture had significantly lower Hb levels and
lower GNRI scores than women with hip OA in the same age and that anemia and undernutrition
were closely linked in women aged 75 and above. Moreover, we found that more than
40% of patients with a femoral neck fracture had a moderate to major risk on the basis
of their GNRI scores.
