Abstract:
0.05)between left AF(238,36.62%)and right AF(220,33.85%).More HIZs(446,68.62%)were located in inferior AF than that of middle or superior AF.The motion segments from L3、4 to L5S1 were the region that the HIZ occurred frequently and it could present in single segment or multi-segment.In anterior AF,HIZs often occurred at L2、3 and/or L3、4 discs.Whereas,they usually developed at L4、5 and/or L5S1 in posterior AF. Conclusion The incidence rate of HIZ in lumbar disc is higher.Posterior and inferior AF of discs and lower motive segments have more risk of HIZs.It could develop in single motive segment or multi-segments at one time.
