Thirty patients who had definite chronic lumboscaral compartment syndrome without other lumbal diseases were choosed respectively to test muscle force of lumbar and abdomen, intra-sacrospinal muscle pressure, blood routine, ESR, Ck, CK-MM LDH and LDHs. All patients received decompressive operation. Skeletal muscle specimens taken from sacrospinal muscle in each operation were possessed for bistological and ultrastrucluml observation. All of enzyme tests were normal.
