股骨颈骨内压的临床研究——动物实验与32例Legg—Perthes病报告

CLINICAL STUDIES ON THE INTRAOSSEOUS PRESSURE OF THE FEMORAL NRCK: A RRPORT OF ANIMAL EXPERIMENT AND THIRTY-TWO CASES OF LEGGPERTHES' DISEASE

近年来,Arnoldi等发现了股骨颈内压改变与骨关节炎有关。国内尚未有关股骨颈内压的研究报告。我们从1984年至1986年开展这方面的动物实验与临床测定,结果报告如下:

The clinical importance of intraosseouspressure of the femoral neck has been notedin the world. But the experimental data onanimals are still absent. The authors reportthe results or determination of intraosseouspressure of the femoral neck in 20 persons.The value of the intraosseous pressure of thebilateral femoral neck was proximally equalwith average of 23.3 mmHg (rifht) and 24.8mmHg (left). The individual case, however,varied in the determined value. The authors also report the results ofdetermination ot intraosseous pressure of thefemoral neck in 32 cases. of Legg-Perthes’disease in different stages On the normalsides the average value was 30.9 mmHg, and38.6 mmHg on the affected sides (P 0.001).It was indicated that intraosseous pressure onthe abnormal sides were increased. Of the thirty-two cases, twenty-six theintraosseous pressure both pre- and postopera-tion were determined, the pressure was decre-ased with a average of 37.5% after decompre-ssion. The long term follow-up results ofthe decompression were still being observed.
