Proximal femoral anatomy in the anteroposterior plane was assessed by analysis of roentgenograms and the relationship between the anatomy and the pattern of osteoarthrosis of the hip was explored. The neck-shaft angle, the height of the femoral head, and the offset of the femoral head were analyzed and the type of osteoarthrosis classified according to(More)
AIMS To investigate the incidence of hip fractures in Maori and nonMaori in New Zealand. METHODS The number of femoral neck fractures in patients over 60 in New Zealand for the years 1989-91 were obtained. The population data for 1991 was obtained from the 1990 census. The number of fractures was standardised for age, and the rate of fractures per 100,000(More)
Invasive candidal infections are encountered with increasing frequency in compromised hosts but bone infection is uncommon. A woman with systemic lupus erythematosus and end-stage renal failure managed by continuous ambulatory peritoneal dialysis developed a painful thoracic kyphosis and a lytic lesion in the vertebral bodies of T10 and T11. Blood cultures(More)
AIMS To examine the incidence, and results of treatment of osteosarcoma in New Zealand between 1981 and 1987. METHOD Data was obtained from the Cancer Registry for all patients registered with osteosarcoma between 1981 and 1987. RESULTS There were 104 patients in the study group. There was a peak incidence in the second decade with a second smaller peak(More)
The potential for femoral head rotation occurring during insertion of a compression hip screw has been investigated. Rotation to up to 30 degrees has been demonstrated, and was not visible on an image intensifier. The insertion of a guide-wire parallel to a hip screw does not control rotation adequately. Small threaded pins do not cause femoral head(More)
Two cases of dislocation of an Insall-Burnstein II knee are reported. They occurred when a rotational force was applied to the loaded knee positioned in extreme flexion. Both dislocations were reduced closed and were found to be stable in the reduced position. The patients did well, and revision surgery was not required. No case of dislocation of this(More)
A 100x100 CMOS image sensor (CIS) occupying an area of 2.25 mm fabricated in a standard 0.35-μm CMOS technology is described. A back to back pixel layout with pixel dimension of 10μmx10μm and a fill factor of 41% is achieved. The pixels in the CIS integrate the photocurrent for time that depends upon the photocurrent to map wide dynamic range (WDR) real(More)
