    The socioeconomic consequences of sports injuries in Randers, Denmark (1991)

    Notes: Prospective epidemiologic data on all sports injuries were collected in a casualty ward for 1 year in a well defined geographical area with 124,321 inhabitants. A total of 1839 sports injuries were registered; 1535 (83%) of those injured completed questionnaires covering the sports, economic and social consequences of the sports injury. The incidence of sports injury was 61 per 1000 active sports players per year and 15 per 1000 inhabitants in the catchment population per year. The injuries resulted in an average sick leave from work of 3 d and 4 weeks out of competition and training; 16% had chronic health problems 2 years after injury and, unexpectedly, as many as 7% stopped participating in sports. The total net loss of income was DKK 147,900 (USD 23,000), an average of DKK 1781 (USD 270) for each person who had a financial loss. Abbreviated Injury Scale scores, hospitalization rates and inpatient time were correlated.

    Notes: Abstract The study presented here is a pilot study in five patients with unstable thoracolumbar spine fractures treated with transpedicular OP-1 transplantation, short segment instrumentation and posterolateral fusion. Recombinant bone morphogenetic protein-7 in combination with a collagen carrier, also referred to as OP-1, has demonstrated ability to induce healing in long-bone segmental defects in dogs, rabbits and monkeys and to induce successful posterolateral spinal fusion in dogs without need for autogenous bone graft. Furthermore OP-1 has been demonstrated to be effective as a bone graft substitute when performing the PLIF maneuver in a sheep model. Five patients with single-level unstable burst fracture and no neurological impairment were treated with intracorporal OP-1 transplantation, posterior fixation (USS) and posterolateral fusion. One patient with osteomalacia and an L2 burst fracture had an additional intracorporal transplantation performed proximal to the instrumented segment, i.e. OP-1 into T 12 and autogenous bone into T 11. Follow-up time was 12–18 months. On serial radiographs, Cobb and kyphotic angles, as well as anterior, middle and posterior column heights, were measured. Serial CT scans were performed to determine the bone mineral density at fracture level. In one case, radiographic and CT evaluation after 3 and 6 months showed severe resorption at the site of transplantation, but after 12 months, new bone had started to fill in at the area of resorption. In all cases there was loss of correction with regard to anterior and middle column height and sagittal balance at the latest follow-up. These preliminary results regarding OP-1 as a bone graft substitute and stimulator of new bone formation have been disappointing, as the OP-1 device in this study was not capable of inducing an early sufficient structural bone support. There are indications to suggest that OP-1 application to a fracture site in humans might result in detrimental enhanced bone resorption as a primary event.

    Gelation and fusion of vinyl plastisols (1966)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The gelation of vinyl plastisols at constant temperature has been found to follow the equation ln [(C - Ce)/(U - Ce)] = (- π2/a2)Dτ + ln (8/π2), where C is the resin phase concentration, Ce the equilibrium resin phase concentration, U the critical resin phase concentration, a the average particle size, D the diffusion constant, and τ the time required for the onsent of gelation. A light reflectance apparatus capable of measuring the gelation process is described. The effect that various resin-plasticizer parameters have on the gelation and fusion process is discussed. The light-reflectance apparatus is also useful for estimating various resin and formulating parameters.
