减压性骨坏死是因高气压作业后减压不当,体内残余的气泡及其继发因素阻塞和压迫了骨骼的营养血管而引起的缺血性骨关节病变。随着潜水事业的迅速发展,减压性骨坏死的发病率逐年增加,受到各国学者的普遍重视,但在脱离高气压作业后的发病情况,尚未引起注意。我院于1962～1988年共检查1140名潜水,沉箱及隧道等高气压作业工人,发现减压性骨坏死152人,
Decompressive osteonecrosis is due to improper decompression after high pressure operation, the body of residual bubbles and its secondary factors blocking and oppression of the bones of the nutrient vessels caused by ischemic bone and joint disease. With the rapid development of diving, the incidence of decompressive osteonecrosis increases year by year, which is widely accepted by scholars all over the world. However, the incidence of decompression osteonecrosis has not drawn any attention since it was separated from high-pressure operation. Our hospital in a total of 1140 from 1962 to check diving, caissons and tunnels and other high pressure workers, found that 152 people with decompressive osteonecrosis,
