Cardiovascular and neurological function in elderly patients sustaining a fracture of the neck of the femur

Abstract

Cardiac and neurological functions were evaluated at the time of operation in 81 randomly selected elderly patients who had sustained a fracture of the neck of the femur. Although only one-fifth of the patients had clinical signs of senile dementia or cerebrovascular disease on admission to hospital, more than half had seriously abnormal EEGs including 12 of the 15 patients who died within six months. ECGs before operation showed that patients with signs of arrhythmia or previous myocardial infarction had a much lower survival rate than those with normal or other pathological ECG signs. Nerve conduction velocity findings proved inconclusive when correlated with survival or return home. Routine EEG and ECG examinations are of value in detecting underlying dysfunctions which may not be observable clinically on admission but are important prognostic indicators for survival or return home, and may be implicated as causative factors of fracture in the elderly.
