Correlation Between Dynamogram and Discogram For Lumbar Disc Lesion

Abstract

The correlation between dynamogram and discogram in 150 cases was studied on the cases of
1) L_3-4, L_4-5 and L₅-S; Normal Discs
2) L_3-4, L_4-5; Normal Discs
L₅-S; Pathological Disc
3) K_3-4; Normal Disc
L_4-5, L₅-S; Pathological Discs
4) L_3-4, L₅-S; Normal Discs
L_4-5; Pathological Disc
The results were as follows;
1) In cases with L_3-4, L_4-5, L₅-S Normal Discs, the mobility of discs tends to increase in order of L₅-S, L_4-5 and L_3-4.
2) Both L_4-5 and L₅-S discs tend to decrease the mobility with the progress of degenerative processes, particularly in L₅-S discs.
