    Earlier wrist fracture: A confounding factor in distal forearm bone screening (1992)

    Notes: Abstract Thirty-six women aged 60, 70 or 80 years who had fractured one of their distal radii (Colles' fracture) 0 to 35 (median 10) years earlier were examined in this population-based study. Single photon measurements (SPA) were performed on both arms 1 cm and 6 cm proximal to the styloid process of the ulna. All women were questioned about earlier wrist fractures and which, if any, side had been affected. Information about the type and site of the fracture was also gathered from the hospital records. The bone mineral content (BMC) was found to be increased by almost 20% in the once-fractured radius at the distal measuring site (1 cm) when compared with the unaffected side. This difference did not seem to diminish with time. At the proximal measuring site there was no difference between the once-fractured and the non-fractured side. There was a progressive loss of bone mineral in the once-fractured arm during the first years after the fracture however. This appeared to be reversed after about 10 years to a relative gain, even though the correlation was weak. Six of the 36 women could not remember which side had been fractured and five could not remember having had such a fracture at all. Determination of osteoporosis by measuring forearm BMC with single photon densitometry is therefore of limited value in some women of the oldest age groups.

    Myelography in the late postoperative period in patients subjected to anterior cervical decompression and fusion (1993)
    Springer
    Acta neurochirurgica 122 (1993), S. 97-101 
    Details
    ISSN: 0942-0940
    Keywords: Cervical spondylosis ; cervical disc ; Cloward procedure ; anterior fusion ; late myelography

    Notes: Summary During a 13 year period, 286 patients with cervical disc herniation and/or spondylotic spurs, were subjected to anterior decompression and vertebral interbody fusion with autologous bone. Twenty patients were re-admitted in the late postoperative period due to recurrent radicular symptoms and/or signs of myelopathy. In these patients myelography was performed again. In 14 patients spinal cord compression and/or nerve root involvement at a new level was visualized. At the operated level, however, the myelograms demonstrated a smooth anterior wall in the spinal canal. The series confirms the safety, effectiveness and reliability of the Cloward procedure in achieving long term spinal cord and nerve root decompression, and a solid vertebral interbody fusion.

    Indicators of bone formation in weight lifters (1995)
    Springer
    Calcified tissue international 56 (1995), S. 177-180 
    Details
    ISSN: 1432-0827
    Keywords: Weight lifters ; Athletes ; Bone turnover ; Osteocalcin

    Topics: Biology , Medicine , Physics
    Notes: Abstract Physical activity has been suggested to be one of the determinants of bone turnover and to prevent age-related bone loss. To examine this we measured the serum levels of osteocalcin (bone Gla-protein, BGP), C-terminal procollagen peptide (PICP), serum alkaline phosphatase, bone-specific alkaline phosphatase, and S-calcium as indices of bone formation in 19 actively performing and 15 ex-lifters. All were nationally or internationally ranked male athletes. Their values were compared with those from 38 age- and gendermatched controls. Actively performing weight lifters had 35% higher (P〈0.05) serum concentration of osteocalcin than the controls. The ex-lifters did not differ from the agematched controls. Also serum calcium was elevated in active lifters (6%) (P〈0.01) but not in ex-lifters. No difference was found for serum-ALP, B-ALP, or PICP in either of the groups. Our study indicates that in addition to an already documented and well-known higher bone mineral density in heavily exercising athletes, they have an indication of higher bone formation as measured by biochemical markers. In athletes who have retired from competitional training, however, the bone formation does not differ from that of more sedentary controls.
