Objective:
To study the value of the classification of the elderly lumbar disc herniation(LDH) as an indication of microendoscopic discectomy(MED).
Methods:
Based on the pathological features of the elderly LDH, eighty-one patients over fifty years old (Group A) were proved to be intraspinal complications by traditional operation and were divided into I and II types which were compared with what were seen in the operation. Sixty-two patients over 50 years old (Group B) were treated with MED and reviewed retrospectively, and their curative effects were compared with their types.
Results:
A general intraspinal narrowness rate of Group A was 62.07% in Type I, 107.69% in Type II (P < 0.01). Group B was all followed up (mean 10 months). According to the macnnab criterion, the satisfactory rate was 100% in Type I, 75% in Type II (P < 0.05).
Conclusion:
The clinical classification of the elderly LDH makes a significant effect on the treatment of MED, can be used as an indication of MED, and can be popularized in clinic.
