Abstract:
BACKGROUND:The reason why elderly human hips tend to break in one of two anatomical regions is uncertain. Nutritional factors may affect the site of fracture. OBJECTIVE:To assess possible nutritional differences in patients with proximal femoral fractures. DESIGN:Prospective observational cohort study. SETTING:University teaching hospital. SUBJECTS:119 consecutive patients over the age of 65 with a hip fracture admitted to the trauma wards in a single centre. METHODS:One researcher measured triceps, biceps and supra-iliac skinfold thickness, and mid upper arm circumference on admission and on the fifth post-operative day. Body mass index was calculated for each patient, and used to classify patients as severely, moderately or mildly malnourished, normal, overweight or obese. Logistic regression was used to determine the influence of various factors on fracture site. RESULTS:According to their body mass index, 31% of patients were classified as malnourished and 11% as severely malnourished. Patients with intracapsular fractures were significantly more malnourished than patients with trochanteric fractures (P < 0.008). Nutritional status was not related to post-operative complications. Ability to weigh a patient on the fifth post-operative day was the single most important prognostic indicator for complications. CONCLUSIONS:Patients with intracapsular fractures are more malnourished. Those with trochanteric fractures tend to be overweight.
