“…Similar results have been recently reported by Erikkson and Widhe [28] indicating that with the new automatic equipment it is possible to observe a significant difference among patients with different types of FXf. A diminished bone mass in trochanteric fractures was suggested by other authors employing radiological [22,31,32] or histomorphometric techniques [33,34]. Trabecular bone volume was significantly lower in trochanteric than in cervical fractures [35].…”

The bone mineral density (BMD) of the proximal femur, spine and radius shaft was determined in 75 women with atraumatic fractures of the proximal femur (FXf) (average age: 70.1 +/- 9.6 years) and 51 controls of similar age. Fractures were classified as either cervical (n = 36) or trochanteric (n = 39) on the basis of radiographic and surgical finding. The BMD of spine and proximal femur was determined by dual-photon absorptiometry (Lunar DP3) and the BMD of the radius shaft by single photon absorptiometry. The BMD of patients with FXf was significantly decreased over all skeletal sites compared to controls of similar age. No significant correlation was found between age and the BMD of the femoral neck in patients with FXf. Patients with trochanteric FXf were older and thinner (average: age, 72.9 +/- 9.4 years; weight, 53.1 +/- 7.8 kg) compared with patients with cervical fractures (age, 67.2 +/- 8.9 years; weight, 59.3 +/- 8.3 kg). Likewise the BMD of trochanteric FXf was lower at all measured sites: femoral neck, 0.548 +/- 0.066 g/cm2 vs 0.624 +/- 0.055 g/cm2 (P less than 0.001); L2-L4, 0.799 +/- 0.115 g/cm2 vs 0.925 +/- 0.106 g/cm2 (P less than 0.001); radius shaft, 0.454 +/- 0.057 g/cm2 vs 0.502 +/- 0.083 g/cm2 (P less than 0.05). Of the patients with trochanteric fractures 66% had concomitant vertebral fractures, while this occurred in only 28% of the patients with cervical fractures (P (Fisher) = 0.0007). In summary, females with trochanteric FXf are older, thinner, have less bone mass in all measured sites and suffer with a significantly greater frequency of vertebral fractures.(ABSTRACT TRUNCATED AT 250 WORDS)

“…In his patients osteoporosis was no more obvious in patients who sustained hip fractures than those who did not, although in general the more elderly patients were more porotic. However, Stevens reported a higher incidence of osteoporosis in patients with transcervical and intertrochanteric fractures than in a control series; this was especially notable in older w o m e n with intertrochanteric fractures [23]. Rowe and Song reviewed 141 patients with fractures about the hip and compared them with 120 controls; 34% of the fracture patients had definite osteoporosis, and 39% were considered borderline.…”

We have undertaken an epidemiological study of fractures of the hip which occurred in the Honam area of Korea during the year 1991. Honam comprises 3 districts, Kwangju, Chonnam, and Chonbuk. On November 1st 1991 the total population over the age of 50 years in Honam was 1,205,370. During the year there were 405 fractures of the neck or intertrochanteric region of the femur, an incidence of 3.4 per ten thousand per year. The age specific incidence rate showed a gradual increase. The incidence rate showed seasonal variations being higher in the summer and fall, and lower in the winter and spring. The incidence in urban areas was higher than in rural regions to a level which was statistically significant. The average age of patients was 70.2 years (range 50 to 94 years). The most common cause of injury was a simple fall (61%). There were 212 females and 193 males, a ratio of 1.1:1. There were 196 fractures of the neck and 209 of the intertrochanteric region. The degree of osteoporosis increased with age. About half of the patients (49.9%) showed definite osteoporosis, the degree being higher in women and in fractures of the neck of the femur. Treatment was by operation in 328 patients (81%); 77 patients were treated conservatively or had no treatment (19%). Of the 360 patients whose final outcome was known, 26 died within three months of injury, a mortality of 7.22%. The mortality was 3.8% (11 out of 292) in patients who underwent operation, whilst it was 22.1% (15 out of 68) in patients who were treated conservatively or remained untreated.(ABSTRACT TRUNCATED AT 250 WORDS)

“…The patient sustaining a hip fracture belongs to a sicker subset of the population. As a group, they are more osteoporotic (Lender et al 1976, Hagberg & Nilsson 1977, Nilsson 1970, Stevens et al 1962, Vose & Lockwood 1965 and factors known to influence the bone mineral content, i.e., gastric resection, certain drugs, osteomalacia (Aaron et al 1974, Bauer 1960, Nilsson 1970, Nilsson gL Westlin 1971, O'Driscoll 1973 are also more frequent. Furthermore, there is an increased proportion of patients with cardiovascular and muscle weakening diseases (Boucher 1959, Dolk & Westerborn 1977, with diabetes mellitus (Alffram 1964, Wong 1966, and with thyrotoxicosis (Gallagher et al 1980).…”
