- 62 former patients, who had been treated at our department for tibial shaft fracture (n 38) or knee ligament injury (n 24) 15-38 years earlier, were re-evaluated for post-traumatic osteopenia. 62 age- and sex-matched subjects without fracture served as controls. By means of a Lunar DEXA apparatus we measured the bone mineral density (BMD) in the total body, the hips and special regions of interest (ROI) in the lower extremities. We found a difference in the BMD between the injured and uninjured legs, most obvious in the femur condyle. Measurements of bone mineral loss early after the injury did not correlate with the present late measurements. The former fracture patients had at the time of follow-up the same BMD in the rest of their bodies as a whole, compared with controls. We conclude that post-traumatic osteopenia is still evident in the injured leg decades after the injury.

- The aims of this study were to measure the bone mineral density (BMD) and some anthropometric variables in patients with hip fracture, to compare these data with those from controls, and to compare the fractured and unfractured hip. Bone mineral measurements with dual energy X-ray absorptiometry (DEXA) were undertaken in 93 consecutive hip fracture patients, 26 men and 67 women, with a mean age of 75 and 78 years, respectively, within 10 days after injury. We found lower BMD in most measurements in both men and women compared with age- and sex-matched controls. The body weight and lean body mass were also significantly lower in the male hip fracture patients; in women only weight was lower. In women there was lower BMD in spine and hip in those who had sustained trochanteric hip fractures compared with those with cervical fracture. No such difference was found in men. There was no difference in BMD in the hip when patients with stable and unstable fractures were compared. In the fractured and nonfractured hips we measured BMD in regions of interest. In women with trochanteric hip fractures the BMD was decreased in the fractured hip compared with the uninjured. No such difference was found for cervical fractures or in men.

- Based on all patients with tibial shaft fracture (n = 767) treated in the department of orthopedics in Malmö from 1955 to 1963, a retrospective cohort study was performed in 1990. Two hundred sixty-nine of the patients were still living in Malmö or had died in the city. Since all roentgenograms were available, all other fractures that this group of patients had sustained up to 1990 were included. Data were compared with an age- and gender-matched control group with respect to location and types of fractures. The group with previous tibial shaft fractures had an increased incidence of all sorts of fractures. When comparing the risk of sustaining new fractures in the previously fractured limb with the uninjured side, only a statistically insignificant tendency toward more fractures was found. A similar tendency was observed in fractures of the upper limb. Therefore, remaining osteopenia in the injured limb after tibial shaft fracture is not associated with further fractures; rather, this group of patients were more fracture prone in general.

- In 1990, a retrospective case control study was performed based on all patients with tibial shaft fractures (n = 767) treated at the Department of Orthopaedics in Malmö 1949-1963. At the time of the study 231 of the patients were still living in Malmö . All radiographic examinations of this latter group from the time of the fracture to 1990 were studied and the occurrence of osteoarthrosis (OA) of the hip, knee and ankle joints were registered. The fracture patients were compared with an age and sex-matched control group. The group with previous tibial shaft fracture had an increased prevalence of OA in the lower extremities compared with the controls. When comparing the risk of OA in the once fractured limb with the uninjured side we found no difference. We conclude that there is no risk of having posttraumatic OA after extra-articular tibial shaft fractures.
