Clinical study on the treatment of sequestrated lumbar disk herniation by feng’s spinal manipulation

Objective: To evaluate the clinical efficacy of treating sequestered lumbar disc herniation (SLDH) with Feng’s spinal manipulation. Methods: 112 patients (52 males, 60 females) with SLDH were treated by Feng’s spinal manipulation. The clinical outcome was evaluated by using the JOA (Japanese Orthopaedic Association) score and Feng’s spinal assessment system for SLDH. The MRI sagittal index (SI) of lumbar disc herniation was measured and compared between preand post-treatment. Result: The scoring of patients’ subjective and clinical symptoms were improved significantly before discharge as well as on follow-up (P<0.05). There was no statistical difference in the SI between preand post-treatment. However, there was significant difference in SI between pre-treatment and follow-up. Conclusion: The leading pathologic change in SLDH is single/multiple vertebral subluxation. Feng’s spinal manipulation can correct the vertebral subluxation which leads to spinal column stability. The clinical signs disappeared with the recovery of spinal column stability.
