Objective To compare the clinical effect of minimally invasive surgery transforaminal lumbar interbody fu-sion(MIS-TLIF)and posterior lumbar interbody fusion(PLIF)in the treatment of recurrent lumbar intervertebral disc hernia-tion(LIDH). Methods Twenty-nine patients with recurrent LIDP were selected from May 2014 to May 2016 in Weifang Peo-ple's Hospital and the clinical data were analyzed retrospectively. Thirteen patients were given MIS-TLIF(MIS-TLIF group) and sixteen patients were given PLIF(PLIF)group. The operative incision length,intraoperative bleeding volume,postoperative drainage volume,hospitalization time and complications were compared between the two groups. The lumbar function was evalu-ated with the Japanese Orthopaedic Association(JOA)score standard,and the clinical effect was compared between the two groups according to the modified Macnab standard one year after treatment. Results The operativeincision length,intraopera-tive bleeding volume,postoperative drainage volumeand hospitalization time in MIS-TLIF group were significantly less than tho-sein PLIF group (P < 0. 05). The preoperative JOA score of lumbar function in PLIF group and MIS-TLIF group was 7. 9 ± 1. 9 and 8. 0 ± 1. 6 respectively,it was 24. 0 ± 2. 7 and 24. 2 ± 2. 5 respectively at one year after treatment,there was no significant-difference in the JOA score between the two groups before and one year after operation (P > 0. 05). The JOA score atone year after operation was significantly higher than that before operation in the two groups (P < 0. 05). According to the modified Macnab standard one year after treatment,the fineness rate of the patients in PLIF group was 87. 50％(14 / 16),the fineness rate of the patients in the MIS-TLIF group was 84. 62％(11 / 13). There was no significant difference in the fineness rate be-tweenthe two groups (χ2 = 1. 380,P > 0. 05). The incidence of postoperative complications in the MIS-TLIF group and PLIF group was 7. 7％(1/ 13)and 6. 3％ (1/ 16)respectively,there was no significant difference in the incidence of postoperative complications between the two groups (χ2 = 0. 020,P > 0. 05). There were 8 cases (61. 5％)with gradeⅠfusion and 5 cases (38. 5％)with gradeⅡfusion in MIS-TLIF group,there were 9(56. 3％)with gradeⅠfusion and 7(43. 8％)with gradeⅡfu-sion,there was no significant difference in the constituent ratio with gradeⅠandⅡfusion between the two groups (χ2 = 0. 080, P >0. 05). Conclusion MIS-TLIF in treatment of recurrent LIDH has the advantages of less incision,less intraoperative bleed-ing,less postoperative drainage and shorter hospitalization time;and the clinical effect of MIS-TLIF is similar to that of PLIF.

BACKGROUND:There are stil about 10%-30%of patients presenting no obvious improvement of symptoms after lumbar disc herniation surgery, which are col ectively known as the lumbar spine post-surgery failure syndrome, and lumbar instability is one of the important reasons. OBJECTIVE:To evaluate the feasibility and efficacy of surgery including posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation on lumbar intervertebral disc protrusion concurring lumbar instability via MAST Quadrant retractor. METHODS:From December 2011 to October 2012, 62 cases of lumbar intervertebral disc protrusion concurring lumbar instability were treated with posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation via MAST Quadrant retractor. There were 38 female and 24 male ranging in age from 37 to 69 years (average 53.7 years). After operation, al patients were fol owed-up to evaluate the effect of the treatment. RESULTS AND CONCLUSION:The operative time was 90-210 minutes, average 145 minutes, and the amount of blood loss was 50-300 mL, average 120 mL. The hospitalization time was 5-9 days, average 6 days. Al incisions healed by first intention. Al patients were fol owed up 7.2 months on average (from 3 to 10 months). The preoperative JOA score was (10.25±2.34) points. The postoperative JOA score decreased to (18.31±3.12) points at the fol ow-up after 1 month and (25.35±2.61) points at the last fol ow-up, showing significant difference when compared with preoperative score (P<0.01). The preoperative VAS score was (8.24±1.15) points. The postoperative VAS score decreased to (2.97±1.12) points after 1 month and (1.13±0.39) points at the last fol ow-up, showing significant difference when compared with preoperative score (P<0.01). According to reforming Macnab standard, the results were excel ent in 53 cases and good in 9 cases at the last fol ow-up. The surgery including posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation via MAST Quadrant retractor is a safe, effective and minimal y invasive surgical technique in treating lumbar intervertebral disc protrusion concurring lumbar instability.

Objective To analyze and study the biomechanical model of oblique-pulling manipulation in traditional Chinese medicine for the treatment of lumbar disc disease such as intervertebral disc protrusion, and compare the mechanical properties of two different manipulations, i.e. traditional oblique-pulling manipulation under impulse excitation and improved oblique-pulling manipulation under harmonic excitation. Methods The vertebra was set as rigid body, while the intervertebral disk and surrounding ligaments as viscoelastic body. A vibration system with 5-degree freedom for simulating lumbar L1-L5 was established. The basic vibration equation was solved using analytical method. Results The effect of improved oblique-pulling manipulation was related to the frequency of harmonic excitation. If the frequency of harmonic excitation was not higher than 1, the maximum displacement of the diseased segment under harmonic excitation was larger than that of traditional oblique-pulling manipulation under impulse excitation. With the lesion location shifted downward, the damage ratio (DR) under harmonic excitation was gradually decreased as compare to that under impulse excitation, indicating the safety of the improved oblique-pulling manipulation increasing. Conclusions The curative effect of oblique-pulling manipulation under harmonic excitation at the frequency lower than 1 was better than that of traditional oblique-pulling manipulation under impulse excitation, especially in that the medical injury can be controlled by oblique-pulling manipulation under harmonic excitation at the frequency no higher than 1.

Objective To study the mechanisms of vertebrae semi-dislocation of Tuina manipulation for treating patients with lumbar intervertebral disc protrusion (LIDP) by observing the three-dimensional (3D) displacement of lumbar before and after Tuina manipulation. Methods Ten LIDP patients were selected and evenly divided into two groups: Group 1 as tendon-smoothing manipulation group (relaxing group), Group 2 as tendon-smoothing plus adjusting manipulation group (adjusting group). Besides, Group 3 as control group was established by 5 healthy volunteers treated with tendon-smoothing manipulation. Before and after manipulation intervention, all subjects were scanned from L1 to L5 segment by using Philips 64 spiral CT under equal conditions for accessing the volume data. ITK reconstruction software was used to reconstruct each lumbar skeleton for finite element analysis. The 3D displacements and angular displacements among three groups were compared. Results 3D displacement from L1 to L5 segment all changed in three groups. For adjusting group, the angular displacements at X-axis in L3 segment was (1.77±0.46)°, and that in L4 segment at X-axis and Y-axis was (1.78±0.53)° and (1.89±0.75)°, respectively, which was significantly larger than relaxing group and control group (P<0.05); the angular displacements at X-axis from L1 to L5 segment were (1.50±0.47)°, (1.55±0.57)°, (1.77±0.46)°, (1.78±0.53)°, (1.61±0.39)°, respectively, which were significantly larger than control group (P<0.05); displacement at Y-axis in L3 segment was (2.87±0.74) mm, and that at X-axis in L4 segment was (1.68±0.64) mm, which were significantly larger than relaxing group and control group (P<0.05); displacement at X-axis in L1, L4 and L5 segment was (1.28±0.21),（1.68±0.64）, (1.30±0.51） mm, and that at Y-axis in L1 to L3 segment was (1.92±0.42), (2.25±0.61), (2.87±0.74) mm, which was significantly larger than control group (P<0.05). The angular displacements and displacements of L1 to L5 segment in relaxing group were larger than those in control group, but without any significant differences. Conclusions Compared with relaxing manipulation, adjusting manipulation played a more obvious adjusting role in instability and degenerative lumbar vertebra, especially for angular displacements in X-axis, and displacements in X-axis and Y-axis. Namely, the mechanisms of vertebrae semi-dislocation of adjusting manipulation were to make horizontal and rotational displacements at lumbar vertebra other than upper and lower displacement. The effect of relaxing manipulation was not so obvious on lumbar structure of LIDP patients.
