As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

OBJECTIVETo evaluate the efficacy and safety of three different spinal rotation manipulations for the treatment of lumbar disc herniation.

METHODSFrom September 2011 to April 2013,180 patients diagnosed as lumbar disc herniation were randomly divided into seat fixed rotation group (A), lateral position rotation group (B) and supine position rotation group (C) by using a digital table. Finally 10 patients were excluded and dropped, 170 patients were included in the study. There were 57 patients in group A, 57 patients in group B and 56 patients in group C. Baseline demographic characteristics of patients, clinical findings and indexes of health status had no statistically differences among three groups (P > 0.05). The manipulation was performed every other day, and the treatment duration for all patients was 3 weeks. Body pain (BP), Physical function (PF) in SF-36, Oswestry Disability Index (ODI) and adverse reactions were observed statistically 6 weeks, 3 months, 6 months, one year and two years after finishing treatment.

RESULTSBP, PF scores in 3 groups were significantly improved and ODI scores were significantly lower than those before treatment and the differences were statistically significant (P < 0.05); However, there was no significant difference among three groups in the BP, PF and ODI scores (P > 0.05). There were no obvious and serious adverse reactions among these groups.

CONCLUSIONBased on the theory of dislocation of bone joints in TCM, three kinds of spinal rotation manipulations can be used safely for the treatment of lumbar disc herniation, and the efficacy was similar.

OBJECTIVETo study the biomechanical relationship between iliac rotation displacement and L(4,5) disc degeneration, and to provide clinical evidences for the prevention and treatment of L(4,5) disc degeneration and herniation.

METHODSFrom March 2012 to February 2014,68 patients with lumbar disc herniation combined with sacroiliac joint disorders were selected. Among them, 42 patients with L(4,5) disc herniation combined with sacroiliac joint disorders included 22 males and 20 females, ranging in age from 19 to 63 years old, with an average of (51.78 +/- 20.18) years old, and the duration of the disease ranged from 1 to 126 months with an average of (11.18 +/- 9.23) months. Twenty-six patients with L5S1 disc herniation combined with sacroiliac joint disorders included 11 males and 15 females, ranging in age from18 to 65 years old with an average of (45.53 +/- 27.23) years old, and the duration of the disease ranged from 0.5 to 103 months with an average of (11.99 +/- 12.56) months. Sixty-eight anteroposterior lumbar radiographs, 68 lateral lumbar radiographs,and 68 pelvic plain films were taken. The degree of lumbar scoliosis, pelvic tilt,and disc thickness were measured. The correlation between pelvic tilt and lumbar scoliosis ,lumbar scoliosis and disc thickness were studied by using linear and regression methods. The hiomechanical analysis was performed.

RESULTSThere was a positive correlation between pelvic tilt and lumbar scoliosis in patients with L(4,5) disk herniation (R=0.49, P=0.00). There was a causal relationship and good linear proportional relationship (Y=3.05+1.07X, P=0.00) in the two variables. There was a negative correlation between lumbar scoliosis and intervertebral space in male patients with L (4,5) disk herniation (R = -0.50, P=0.01). There was a causal relationship and good linear proportional relationship in the two variables (Y=13.09-0.27X, P=0.02). But there was a positive correlation between lumbar scoliosis and intervertebral space in male patients with L5S1 disk herniation (R=0.46, P=0.04).

CONCLUSIONIliac rotational displacement are closely related with L(4,5) disc degeneration and herniation in biomechanics. A new concepts and therapeutic approach is provided for clinical treatment of chronic and refractory herniation of L(4,5) disc in patients

OBJECTIVE: The objective of this study was to compare the clinical outcomes of the cervical interlaminar epidural steroid injection (CIESI) for unilateral radiculopathy by the midline or paramedian approaches and to determine the prognostic factors of CIESI. MATERIALS AND METHODS: We retrospectively analyzed 182 patients who underwent CIESI from January 2009 to December 2012. Inclusion criteria were no previous spinal steroid injection, presence of a cross-sectional image, and presence of follow-up records. Exclusion criteria were patients with bilateral cervical radiculopathy and/or dominant cervical axial pain, combined peripheral neuropathy, and previous cervical spine surgery. Short-term clinical outcomes were evaluated at the first follow-up after CIESI. We compared the clinical outcomes between the midline and paramedian approaches. Possible prognostic factors for the outcome, such as age, gender, duration of radiculopathy, and cause of radiculopathy were also analyzed. RESULTS: Cervical interlaminar epidural steroid injections were effective in 124 of 182 patients (68.1%) at the first follow-up. There was no significant difference in the clinical outcomes of CIESI, between midline (69.6%) and paramedian (63.7%) approaches (p = 0.723). Cause of radiculopathy was the only significant factor affecting the efficacy of CIESI. Patients with disc herniation had significantly better results than patients with neural foraminal stenosis (82.9% vs. 56.0%) (p < 0.001). CONCLUSION: There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy. The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis.

OBJECTIVETo investigate the effects of spinal manipulation (SM) on brain functional activity in patients with lumbar disc herniation (LDH).

METHODSEleven patients with LDH were recruited in the study. All patients received 6 times of lumbar SM treatment and then clinical efficacy was evaluated. All patients received brain functional magnetic resonance imaging (fMRI) scans before and after SM treatment.

RESULTSThree subjects dropped out and 8 subjects completed the study, among whom 4 cases were effective and 4 ineffective after SM treatment. The required pressure value producing the same level (VAS 50) pain was (7.43 ± 1.47) kg and (10.53 ± 0.55) kg before and after SM treatment in effective patients(P<0.05); however, there was no significant difference in ineffective patients (P>0.05). Compared to pre-treatment level, the brain functional activity in effective patients was mainly inhibited, the inhibited areas were located in the right side of prefrontal cortex and cerebellum; while the brain functional activity was generally enhanced in ineffective patients.

CONCLUSIONSM can affect the brain functional activity of patients with LDH, the inhibited areas is mainly located in prefrontal cortex and cerebellum when SM treatment is effective.

OBJECTIVETo explore the clinical effect of transforaminal lumbar interbody fusion (with single cage) combined with unilateral pedicle screw fixation in treating lumbar instability.

METHODSThe clinical data of 50 patients with lumbar instability were retrospectively analyzed. They underwent treatment and obtained following up more than 8 months from 2009 to 2012. All patients complicated with refractory or recurrent lower back pain, and unilateral primarily or unilateral lower limb radiation pain, X-ray and CT films showed lumbar instability. The patients were respectively treated with transforaminal lumbar interbody fusion (with single cage) combined with unilateral or bilateral pedicle screw fixation. According to different fixation methods, they divided into unilateral fixation group and bilateral fixation group. There were 20 patients with 22 intervertebral spaces in unilateral fixation group, 8 males and 12 females, aged from 26 to 66 years old, 2 cases with isthmic spondylolisthesis of degree I, 8 cases with degenerative spondylolisthesis, 10 cases with lumbar disc herniation; fusion location with L3,4 was in 1 case, L4,5 was in 12 cases, L5S1 was in 9 cases. There were 30 patients with 30 intervertebral spaces in bilateral fixation group, 14 males and 16 females, aged from 41 to 62 years old, 4 cases with isthmic spondylolisthesis of degree I,14 cases with degenerative spondylolisthesis, 12 cases with lumbar disc herniation; fusion location with L3,4 was in 3 cases, L4,5 was in 15 case, L5S1 was in 12 cases. Operation time, intraoperative blood loss, postoperative drainage, complications were analyzed and intervertebral height, lordosis angle changes, fusion rate and clinical effect were compared between two groups.

RESULTSAll incisions obtained primary healing,lower limb radiation pain and low back pain disappeared basically, no infection, endorachis injury was found. Foot drop occurred in one case of bilateral fixation group and no iatrogenic neurological symptom was found in unilateral fixation group. All patients were followed up from 8 to 18 months with an average of (10.8?4.3)months. Ac- cording to JOA score improvement rate (RIS) to assess clinical effect, all patients got excellent and good results, there was no statistically significant difference between two groups. Two methods can both effectively increase the pathological intervertebral height. Unilateral fixation group was better than bilateral fixation group in aspect of operation time, intraoperative blood loss and postoperative drainage.

CONCLUSIONWith strict indication and good skills, transforaminal lumbar interbody fusion (with single cage) combined with unilateral pedicle screw fixation in treating lumbar instability has advantages of smaller traumatic, less blood loss, faster recovery for the patient and can reduce the economic cost.

OBJECTIVETo explore the clinical effects of unilateral pedicle screw fixation and transforaminal lumbar interbody fusion (TLIF) through paraspinal muscle approach for recurrent lumbar disc herniation combined with lumbar instability.

METHODSA total of 35 patients with recurrent lumbar disc herniation combined with lumbar instability were treated between March 2008 and May 2010, including 15 patients managed by the paraspinal muscle approach with unilateral pedicle screw fixation and transforaminal lumbar interbody fusion (TLIF) (unilateral fixation group) and 20 patients by the posterior midline approach with bilateral pedicle screw fixation and posterior lumbar interbody fusion (bilateral fixation group). Operation time and intraoperative blood loss were observed, preoperative and postoperative JOA score and VAS score in low back pain and legs pain, the interbody fusion condition were compared between two groups.

RESULTSAll patients were followed up from 6 to 30 months with an average 16.8 months. All clinical symptoms had obviously improved postoperatively. X-rays showed good interbody fusion (only 1 case did not obtain fusion in bilateral fixation group) without cage displacement or settlement and implant loosening or breakage. There was significant difference in operation time and the intraoperative blood loss between two groups (P < 0.05). Postoperative JOA score had obviously decreased than preoperative one (P < 0.05). At 1 week after surgery, there was significant difference in VAS score of low back pain between two groups and there was no significant difference in VAS score of legs pain between two groups (P > 0.05); at final follow-up, there was no significant difference in VAS score of low back pain and legs pain between two groups (P > 0.05).

CONCLUSIONTwo methods both can obtain satisfactory effect in treating recurrent lumbar disc herniation combined with lumbar instability. Through the paraspinal muscle approach with unilateral pedicle screw fixation and TLIF has advantages of smaller surgical incision, shorter operation time, less intraoperative blood loss, faster relief in low back pain after operation, etc.

OBJECTIVETo study the correlation between lumber disc degeneration and sacroiliac joint disorder, in order to provides a new understanding concepts and therapeutic approach for the prevention and treatment of chronic intractable low back pain.

METHODSFrom August 2009 to October 2010,129 cases with lumbar disc herniation were studied with epidemiological methods. Among them, 61 patients with L4, disc herniation included 37 males and 24 females, ranging in aged from 20 to 75 years old, duration of the disease ranged from 1 to 144 months; The other 68 patients with L5S1 disc herniation included 32 males and 36 females,ranging in aged froml8 to 76 years old,duration of the disease ranged from 0.5 to 240 months. The clinical data, symptoms and signs,X-ray characteristics of lumbar spine and pelvis of the patients were investigated by epidemiological. The risk of lumbar disc herniation was calculated with case-control study; independent variables were screened with single factor analysis; the risk factors for lumbar disc herniation were determined with logistic regression analysis, and biomechanics analyses were taken.

RESULTSAmong 129 patients with lumbar disc herniation, 88 cases associated with sacroiliac joint disorders, sacroiliac joint disorder was a risk factor of lumbar disc herniation (OR = 4.61, P = 0.00); 47 cases associated with sacroiliac joint disorders in 61 patients with L4,5 disc herniation, iliac crest uneven caused by iliac rotational displacement was a high risk factor of L4,5 disc herniation (OR = 11.27, P = 0.00); 41 cases associated with sacroiliac joint disorders in 68 patients with L5S1 disc herniation, lumbar sacral angle abnormalities caused by sacral tilt shift was a high risk factor L5S1 disc herniation (OR = 2.31, P = 0.03).

CONCLUSIONLumbar disc herniation and sacroiliac joint disorder are two of fallot, the two factors affect each other and there is a causal relationship. They are common exists in low back pain.

OBJECTIVETo compare the differences in the clinical function and lumbar and abdominal myodynamia in patiants of lumbar disc herniation treated with moxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and acupuncture.

METHODSForty cases were randomized into a moxibustion group and an acupuncture group, 20 cases in each group. In the moxibustion group, the warm moxibustion was applied alternatively at Dazhui (GV 14) and Guanyuan (CV 4) once every other day, 1 h each time, once every day. In the acupuncture group, acupuncture was applied to the corresponding acupoints based on the affected lumbar vertebras, such as Jiaji (EX-B 2), Shens-hu (BL 23), Dachangshu (BL 25) and Huantiao (GB 30), etc. , once evey day 30 min each time. The treatment for 3 weeks was taken as one session in each group. Totally, one session treatment was required. Surface electromyography (SEMG) of bilateral paraspinal muscle and rectus muscle, and JOA score of low back pain were observed in the two groups.

RESULTS(1) JOA score: the score of subjective symptoms, score of activity of daily living (ADL) and total score were improved obviously as compared with those before treatment in the two groups (P<0.01, P<0.05). The results of subjective symptoms score, score of ADL and total score in the acupuncture group were superior to those in the moxibustion group after treatment (6.95+/-0.94 vs 5.50 +/-0.89,10. 90+/-1.86 vs 8.90+/- 1. 92,22.50 +/- 2.82 vs 19.35 +/- 2. 70, all P<0. 05). (2) SEMG comparison: root-mean-square value (RMS) was all reduced in SEMG of the anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle as compared with those before treatment in the two groups (P< 0.05, P<0. 01). RMS of the anteflexion and bilateral bending in the acupunture group were reduced much obviously as compared with the moxibustion group. In terms of sitting position anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle, median frequency (MF) after treatment was all improved as compared with that before treatment in the two groups (P<0. 05, P<0. 01). In terms of anteflexion, the electrode MF after treatment was improved much obviously in the acupuncture group(P<0. 05).

CONCLUSIONMoxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and conventional acupuncture all improve muscle function, relieve muscle fatigue, increase the ability of anti-muscle fatigue, strengthen lumbar vertebral stability, release subjective symptoms and improve ADL. But, the effects of moxibustion are slightly lower than those of acupuncture.
