Abstract

The risk of fracture of the proximal femur is high for individuals with metabolic bone disease, or with low bone mass associated with advanced age. The menopause is generally believed to be an important factor in bone loss in women. In these group, even minor trauma(low energy injury) may result in fractures, while much greater force is needed to produce a fracture in people with higher bone mass. This study is aimed at ascertaining the age, sex and type-specific incidences in the hip fracture, the difference of frequency between the neck and trochanteric fracture and the change in the averse age of the hip fracture patient. All patient from this hospital with a diagnosis of fracture of the neck and trochanteric region of the femur during the period 1983 to 1992 were reviewed for this study. Patients with fracture resulting from metastatic lesions were excluded. The original medical records were reviewed for each patient, data were entered on protocol disinged for the study. The data included basic demographic informations such as patients age and sex, type of fracture of the femur neck or trochanter, type of the low/high energy injury, immediate cause of accidents, presence of the cormorbid diseases, and safety factors inducing fall accidents in home or outside. During the years 1983-1992, a total 240 patients with fractures of the proximal femur were identified from the operating recordings. Among them, data of 201 patients could be entered on protocol through the retrieved records. 1. Of 201 patients, 65 years or older are 117. 39 are men and 78 are women, 103 are low energy injury and 14 are high,57 are sustained by fractures on the neck of the femur and 60 are sustained on the trochanter. 2. Mean age of the 117 patients over 65 years old is 76 years. Those of men and women are equaly 76 years old. 3. Of 57 patients sustained with the fractures on the neck of the femur, their mean age is 71 years. Men are 18 patients, their mean age is 76 years. Women are 39 patients, their mean age is 75 years. 4. Of 60 patients sustained with the fractures on the trochanter of the femur, mean age is 76 years. Men are 22 patients, their mean age is 75 years. Women are 38 patients, their mean age is 77 years. 5. The cormorbid common diseases are the hypertension, cataract, diabetes mellitus(DM), celebre-vascular accidents(CVA), pulmonary tuberculosis, asthma, chronic obstrutive polmonary disease(COPD), mitral insuficiency(Ml), chronic heart failure(CHF), and chronic renal failure(CRF) in order of.
