Brief Summary:
Hyponatremia was defined as a serum sodium concentration \<135 mmol/L that occurred at least once during a patient's hospital stay from admission to discharge. Elderly patients with fragility fractures are particularly susceptible to hyponatremia because of their impaired physiology, multiple comorbidities (such as hypocortisolism, hypothyroidism, hepatic cirrhosis, renal disease, and congestive heart failure), polypharmacy (e.g., antihypertensives, antidepressants, and antiepileptics), hospitalization, perioperative fluid restrictions, and homeostatic stress from the fracture itself and the subsequent surgery.
The study has 2 parts:
Part 1: aims to to find incidence of hyponatremia in sample of 70 elderly patients with fractures around the hip, effect of hyponatremia on mental state of the patients by using Modified Mini-Mental state (3MS) examination and to find mortality rate for 6 months post admission.
Part 2: aims to compare sample of 18 elderly hyponatremic patients with fractures around the hip (case group) with sample of 10 elderly normonatremic patients with osteoartharitis of knee or hip who admitted for elective joint replacement (control group) as regards; serum sodium, 3M score, and CSF glutamate to find correlation between the cognitive status assessed by 3M score and CSF glutamate as a biomarker for hyponatremia.

Detailed Description:
These patients are also at a higher risk of the complications of hyponatremia such as brain injury, the main result of acute symptomatic hyponatremia and associated with significant morbidity and mortality. Severe hyponatremia (i.e., a serum sodium concentration \<125 mmol/L) ), if unrecognized in its first stages and left untreated, has a high rate of mortality; for this reason, an accurate clinical assessment must be made, focusing on fluid status, examining the potential etiology, and conducting the appropriate investigations. In approximately 50% of patients, chronic hyponatremia results from inappropriate antidiuretic hormone secretion. Chronic mild hyponatremia is usually asymptomatic and is traditionally regarded as benign. However, it is associated with a lower bone mineral content and density in nearly all regions of the hip, with more pronounced losses in the trochanteric and femoral neck regions. It can also lead to osteoporosis, abnormal gait patterns, cognitive impairment, bone demineralization, respiratory failure, noncardiogenic pulmonary edema, falls, and fractures. Compared to normonatremic individuals, hyponatremic individuals are known to have a longer time from admission to surgery.
Glutamate which is the main excitatory neurotransmitter in our body may play role in implication of hyponatremia on the brain. Cerebrospinal fluid (CSF) sample can be taken while dripling during spinal anathesia for surgical intervention for determination of glutamate
