The correlation of hip fracture and hyponatremia in the elderly.
Summary of "The correlation of hip fracture and hyponatremia in the elderly."
Background: Increasing age is considered one of the risk factors for hyponatremia. The concept of asymptomatic hyponatremia is not correct anymore as these patients have a greater risk for falls, bone fractures and attention impairment. The combination of old age and a fall is a common recipe for admission to a nursing home. Methods: We identified 249 patients 65 years of age or older who were admitted to hospital with the diagnosis of hip fracture secondary to fall, during a 3-year period. We compared their serum Na level on admission with that of controls: 44 ambulatory patients admitted for elective hip or knee replacement surgery during the same time frame. Odds ratios (ORs) were calculated using logistic regression. Results: The prevalence of hyponatremia in cases was 16.9%, versus 4.6% in controls (p=0.03). Age and hyponatremia were strongly correlated with hip fracture secondary to fall. The univariate OR for hip fracture associated with each 10-year increase in age was 5.57 (p<0.0001). After controlling for age, cases were almost 5 times as likely as controls to be hyponatremic (OR=4.80, p=0.04). Conclusions: Even mild hyponatremia in the elderly should be considered a risk factor for falls. Correction of hyponatremia in the elderly may reduce morbidity and mortality, and at the same time, it has a huge impact on socioeconomic status.

Medical and Biotech [MESH] Definitions
Bone Plates
Implantable fracture fixation devices attached to bone fragments with screws to bridge the fracture gap and shield the fracture site from stress as bone heals. (UMDNS, 1999)
Monteggia's Fracture
Fracture in the proximal half of the shaft of the ulna, with dislocation of the head of the radius.
Fracture Fixation
The use of metallic devices inserted into or through bone to hold a fracture in a set position and alignment while it heals.
Myelinolysis, Central Pontine
A demyelinating condition affecting the PONS and characterized clinically by an acute progressive QUADRIPLEGIA; DYSARTHRIA; DYSPHAGIA; and alterations of consciousness. Pathologic features include prominent demyelination in the central PONS with sparing of axons and neurons. This condition is usually associated with systemic disorders such as HYPONATREMIA; chronic ALCOHOLISM; LIVER FAILURE; severe BURNS; malignant NEOPLASMS; hemorrhagic PANCREATITIS; HEMODIALYSIS; and SEPSIS. The rapid medical correction of hyponatremia has been cited as a cause of this condition. (From Adams et al., Principles of Neurology, 6th ed, pp1125-6)
Housing For The Elderly
Housing arrangements for the elderly or aged, intended to foster independent living. The housing may take the form of group homes or small apartments. It is available to the economically self-supporting but the concept includes housing for the elderly with some physical limitations. The concept should be differentiated from HOMES FOR THE AGED which is restricted to long-term geriatric facilities providing supervised medical and nursing services.
