ABSTRACT
Objective:To explore the relationship between kinesiophobia and somnipathy among inpatients with lumbar degenerative disease after surgery, and analyze the mediating effects of post-traumatic stress disorder and family care.Methods:A cross-sectional survey method was adopted, from July 2020 to July 2022, a total of 130 lumbar degenerative disease patients from Wuhan Dongxihu District People′s Hospital were enrolled as research object by convenience sampling method. General information questionnaire, Tampa Scale for Kinesiophobia, Pittsburgh Sleep Quality Index, Posttraumatic Stress Checklist-civilian version and Family APGAR index were used for investigation. A structural equation model was established to evaluate the mediating effect of post-traumatic stress disorder, family care on kinesiophobia and somnipathy.Results:The scores of kinesiophobia, somnipathy, post-traumatic stress disorder and family care were (39.95 ± 3.90), (7.63 ± 0.46), (25.99 ± 4.99), (5.67 ± 1.76) points, respectively. There were significant differences in the scores of somnipathy in terms of age, monthly income, course of disease and pain degree ( F values were 3.21 to 10.12, all P<0.05). The dimensions and total scores of somnipathy were positively correlated with kinesiophobia ( r values were 0.347 to 0.800, all P<0.05) and post-traumatic stress disorder ( r values were 0.385 to 0.825, all P<0.05), negatively correlated with the scores of family care ( r values were - 0.653 to - 0.282, all P<0.05); the scores of family care was negatively correlated with kinesiophobia and post-traumatic stress disorder ( r = - 0.695, - 0.637, both P<0.05); the scores of kinesiophobia was positively correlated with post-traumatic stress disorder ( r = 0.773, P<0.05). The indirect effect of kinesiophobia on somnipathy was identified, and the total indirect effect value was 0.44; the indirect effect value of family care and post-traumatic stress disorder was 0.09, which accounted for 12.0% of the total effect. Conclusions:Post-traumatic stress disorder and family care play a multiple mediating role on the relationship between kinesiophobia and somnipathy in patients with lumbar degenerative disease after surgery.
ABSTRACT
OBJECTIVE@#To evaluate the effects of electromyography on the clinical manifestations and prognosis after posterior lumbar interbody fusion(PLIF) of degenerative lumbar diseases.@*METHODS@#A retrospective analysis was performed on 68 patients with degenerative lumbar diseases, including 29 males and 39 females, aged 21 to 84 years old, who underwent electromyogram (EMG) from January 2018 to October 2019. The patients were divided into negative and positive groups according to whether theresults of EMG was normal or abnormal, PLIF surgery was performed in both groups. The preoperative duration of illness, postoperative recovery time, operative time, intraoperative blood loss, postoperative ambulation time and length of postoperative hospital stay were recorded. The clinical efficacy was evaluated by visual analogue scale(VAS) of low back and lower limb, the Japanese Orthopedic Association(JOA) score before and after operation.@*RESULTS@#All patients were follow-up from 26 to 39 months. The subjective symptoms, clinical signs, daily activities and JOA total scores after operation in two groups were significantly higher than those before preoperation(P<0.05);the clinical signs score and total JOA score in the negative group at 3 months after operation were higher than those in the positive group(P<0.05). The VAS score of leg pain in the negative group after 1 and 3 months was less than that in the positive group(P<0.05). Patients 's illness time, postoperative recovery time, hospitalization time and implantation time in the negative group were shorter than those in the positive group(P<0.05). At other time points, there was no significant difference in low pain VAS, leg pain VAS, JOA scores in the two groups(P>0.05). There was no significant difference in the operation time and intraoperative bleeding volume between the two groups(P>0.05).@*CONCLUSION@#Patients with normal electromyography had shorter disease duration than ones with abnormal electromyography in lumbar degenerative disease;after PLIF, patients with normal electromyography recovered faster than ones with abnormal electromyography, but the results of electromyography had no effect on the final prognosis of PLIF surgery.

Wallis dynamic stabilization system is a surgical approach in the non-fusion technique of lumbar spine, consisting of interspinous blockers and dacron artificial ligaments that provide stability to the spine while maintaining a degree of motion in the affected segment. Recent studies have demonstrated the significant benefits of Wallis dynamic stabilization system in treating lumbar degenerative diseases. It not only improves clinical symptoms, but also effectively delays complications such as adjacent segmental degeneration. This paper aims to review the literature related to the Wallis dynamic stabilization system and degenerative diseases of the lumbar spine to describe the long-term prognostic effect of this system in the treatment of such diseases. This review provides a theoretical basis and reference for selecting surgical methods to treat degenerative diseases of the lumbar spine.

The lower the BMD, the more severe the lumbar degenerative disease.
ABSTRACT
The implantation of interspinous process device is a minimal invasive surgical procedure for degenerative lumbar spinal diseases. At present, a variety of interspinous process devices designed can be subdivided into three categories based on different application principles: interspinous distraction device, interspinous fixation device and interspinous fusion device. The interspinous distraction devices distract interspinous interspace, enlarge spinal canal area and alleviate neurological symptom, which are mainly applied for lumbar spinal stenosis with intermittent neurogenic claudication. Interspinous fixation device has been used as an alternative technique to the pedicle screw fixation in lumbar interbody fusion due to gripping and fixating to spinous process. Interspinous fusion device utilizes rigid fixation to support fusion, which can be used as not only simple distraction device but also additional instrumentation for direct decompression and interbody fusion. All types of interspinous process devices are different in biomechanical characteristics due to its application concept. In this review, the author mainly focus on biomechanical research progress of interspinous process device in lumbar degenerative disease.
ABSTRACT
BACKGROUND: The non-fusion system of lumbar interspinous process distraction device provides a new treatment option for lumbar degenerative diseases. However, at present, the clinical application and research of lumbar interspinous process distraction device are reported insufficiently in China, especially for the domestic lumbar interspinous process distraction device. OBJECTIVE: To verify the scientific nature and effectiveness of the new domestic lumbar interspinous process distraction device through finite element analysis and in vitro biomechanical experiment of goat lumbar spine. METHODS: (1) Finite element analysis of new domestic lumbar interspinous process distraction device: L2-L5 three-dimensional model of vertebral body was established based on normal adult lumbar CT data. From then on, new domestic lumbar interspinous process distraction device model, new lumbar interspinous process distraction device model of lumbar non fusion system were successively built. The mechanical conditions were given under the physiological conditions of lumbar spine. Biomechanical analysis was carried out before and after the new domestic lumbar interspinous process distraction device was implanted. (2) In vitro biomechanical analysis of new domestic lumbar interspinous process distraction device: the lumbar vertebrae (L1-L5) of 24 adult male goats were obtained, and the new domestic lumbar interspinous process distraction device was implanted between the L3-4 spinous process. Before and after the placement of the lumbar interspinous process distraction device, the lumbar motion range and the pressure of the intervertebral disc under the flexion, extension, lateral bending and rotation of the lumbar specimens were detected. RESULTS AND CONCLUSION: (1) After the new lumbar interspinous process distraction device was implanted, the motion range and the pressure of the intervertebral disc of responsible segment were reduced, while the adjacent segments' mobility and the pressure of the intervertebral disc were almost unaffected. It was theoretically verified that the new domestic lumbar interspinous process distraction device could provide the biomechanical basis for the treatment of the lumbar degenerative diseases, and contribute to the theoretical reference for the prevention of the clinical diseases. (2) In the state of extension, the motion range of L3-4 vertebral body after implanting the new lumbar interspinous process distraction device was significantly lower than that before implantation (P 0. 05). In the state of flexion, lateral bending and rotation, there was no significant difference between L2-3, L3-4 and L4-5 vertebral body after implanting the lumbar interspinous process distraction device and that before implantation (P > 0. 05). In the state of extension, the pressure of intervertebral disc after L3-4 vertebral body implantation was significantly lower than that before implantation (P 0. 05). In the state of flexion, lateral bending and rotation, there was no significant difference between L2-3, L3-4 and L4-5 vertebral body implantation and that before implantation (P > 0. 05). (3) The results showed that the scientific nature and validity of the new domestic lumbar interspinous process distraction device was verified by three-dimensional finite element analysis and in vitro animal lumbar specimens experiment, which provided a strong basis for the animal experiment, clinical experiment, clinical application and clinical production of the new domestic lumbar interspinous process distraction device.
ABSTRACT
BACKGROUND: Decompression-fixation-fusion is the key to spinal surgery since early effective fixation to achieve intervertebral fusion can restore spinal stability in lumbar degenerative disease. OBJECTIVE: To compare biomechanical stability of fusion segment and adjacent segments of bilateral pedicle screw fixation, unilateral pedicle screw fixation and unilateral pedicle screw combined with contralateral translaminar facet screw fixation under transforaminal lumbar interbody fusion. METHODS: Eighteen fresh calf L3-5 specimens were selected. Different forms of fixation were conducted under transforaminal lumbar interbody fusion. The specimens were divided into group A (complete specimens) and group B (bilateral pedicle screws), group C (unilateral pedicle screws), and group D (unilateral pedicle screw combined with contralateral translaminar facet screw). The range of motion of adjacent segment L3-4 and fusion segment L4-5 in six directions of backward extension, forward bending, left bending, right bending, left rotation and right rotation and the stiffness of fusion segment L4-5 were tested. RESULTS AND CONCLUSION: (1) For the range of motion of fusion segment L4-5, the stability was highest in the group B in six directions, followed by group D, which showed similar results in rotation in the group B (P > 0.05). The stability of right curvature and left rotation in group C was insufficient, and there was no significant difference in range of motion between group A and group C (P > 0.05). The range of motion in group A was largest and the stability was worst in the six motion directions. (2) For the stiffness value of fusion segment L4-5, the stiffness value of group B was largest in six directions, which was significantly different from other groups (P 0.05). There was no significant difference between group C and group A in the range of motion of six directions (P > 0.05). (4) The results showed that the motion ramge of unilateral pedicle screw fixation in the right and left rotation directions was large in the early stage, which was close to that of the complete specimen group. There is a shortage of stability, so we need to use it carefully and grasp the indications strictly. Unilateral pedicle screw fixation combined with contralateral translaminar facet screw fixation improves the disadvantages of asymmetric fixation of unilateral pedicle screw, increases the stability of rotation and lateral bending, and avoids the influence of bilateral pedicle screw fixation on adjacent segments, thus becoming an effective clinical surgical treatment.
ABSTRACT
Objective: To analyze the restoration of intervertebral height and lordosis of fusion segment after open-transforaminal lumbar interbody fusion (Open-TLIF) and minimally invasive-TLIF (MIS-TLIF). Methods: Between January 2013 and February 2016, patients who treated with TLIF due to lumbar degenerative diseases and met the selection criteria were selected as the study objects. Among them, 41 patients were treated with open-TLIF (Open-TLIF group), 34 patients were treated with MIS-TLIF (MIS-TLIF group). There was no significant difference between the two groups ( P>0.05) in gender, age, body mass index, disease type, disease duration, pathological segment, and other general data. The intraoperative bleeding volume, hospital stay, visual analogue scale (VAS) score of waist and leg, and Oswestry disability index (ODI) were recorded before and after operation. The anterior disc height (ADH), posterior disc height (ADH), and segmental lordosis (SL) of fusion segment were measured by X-ray film before and at 6 months after operation. The differences of ADH, PDH, and SL between pre- and post-operation were calculated. Results: The intraoperative bleeding volume and hospital stay in Open-TLIF group were significantly higher than those in MIS-TLIF group ( t=14.619, P=0.000; t=10.021, P=0.000). All incisions healed by first intention without early complications. All patients were followed up 6-24 months (mean, 12.6 months) in Open-TLIF group and 6-24 months (mean, 11.5 months) in MIS-TLIF group. The preoperative VAS scores of waist and leg and ODI of the two groups significantly improved ( P0.05). Imaging examination showed the good intervertebral fusion. There was no significant difference in ADH, PDH, and SL between the two groups before operation and at 6 months after operation ( P>0.05). The differences of ADH, PDH, and SL between the two groups were not significant ( P>0.05). The ADH, PDH, and SL after operation significantly increased in the two groups ( P<0.05). Conclusion: Open-TLIF and MIS-TLIF show similar effectiveness and radiological change in the treatment of single lumbar degenerative diseases and the improved intervertebral height and lordosis, but MIS-TLIF can significantly reduce hospital stay and intraoperative blood loss.
ABSTRACT
STUDY DESIGN: Retrospective study.OBJECTIVES: To compare the degeneration of sacroiliac joint (SIJ) following lumbar or lumbosacral fusion.SUMMARY OF LITERATURE REVIEW: The SIJ is adjacent to lumbosacral junction and its degeneration can be the potential cause of pain. However, the study addressing SIJ degeneration following lumbar or lumbosacral fusion is very limited.MATERIALS AND METHODS: From June 2002 to June 2012, 98 patients who underwent posterior decompression and posterolateral fusion were included in this study. The study group was divided into 2 groups according to the range of fusion. Group A had fusion to L5 and included 34 patients. Group B had fusion to S1 and included 64 patients. We evaluated the five years postoperative radiologic and clinical outcomes retrospectively.RESULTS: There was no statistically significant difference of bilateral preoperative subchondral sclerosis and osteophytes of the SIJ between group A and group B. However, group B revealed statistically significant subchondral sclerosis and osteophyte formation of the SIJ than group A on every radiographs after postoperative 1 year. In group B, the number of fusion segments and age were statistically positively correlated with the degeneration of the SIJ.CONCLUSIONS: Degeneration of the SIJ revealed more rapid and more severe progression in lumbosacral fusion group than in lumbar fusion group. The number of fusion segments and age were positively correlated with the degeneration of the SIJ in lumbosacral fusion group. Therefore, these facts should be taken into account when performing spinal fusion.

STUDY DESIGN: Retrospective study. PURPOSE: Associations among risk factors related to adjacent segmental disease (ASD) remain unclear. We evaluated the risk factors and segmental lordosis ratio to prevent ASD developing after lumbar spinal fusion. OVERVIEW OF LITERATURE: Risk factors related to ASD development are age, sex, obesity, pre-existing degeneration, number of fusion segments, and decreased postoperative lumbar lordosis (LL). However, the associations among these factors are still unclear and should be clearly identified. METHODS: We retrospectively reviewed data on 274 patients who underwent lumbar spinal fusion of three segments or below for lumbar degenerative disease from January 2010 to December 2012, with over 5 years of follow-up. Patients with preoperative sagittal vertical axis (SVA) >5 cm were excluded due to sagittal imbalance. A total of 37 patients with ASD and 40 control patients (CTRL) were randomly selected in a similar distribution of matching variables: age, sex, and preoperative degenerative changes. Sex, age, number of fusion segments, radiologic measurements, L4–5–S1/L1–S1 LL ratio, and spinopelvic parameters (pelvic incidence [PI], pelvic tilt [PT], sacral slope [SS], and SVA) were analyzed. Logistic regression was used to analyze the correlation between PI–LL mismatch and L4–5–S1 segmental lordosis rate. RESULTS: No significant difference was found between ASDs and CTRL groups regarding age, sex, number of fusion segments, fusion method, and preoperative and postoperative spinopelvic parameters (PI, SS, PT, and LL). However, regarding the L4–5–S1/L1–S1 lordosis ratio, 50% (p=0.045), 60% (p=0.031), 70% (p=0.042), 80% (p=0.023), and 90% (p=0.023) were statistically significant; 10 group, and the difference was statistically significant (p=0.048). CONCLUSIONS: Patients with a postoperative L4–5–S1/L1–S1 lordosis ratio >50% had less occurrence of ASD. Correcting LL according to PI and physiologic segmental lordosis ratio is important in preventing ASD.

Objective: To analyze the medium and long-term effectiveness of microendoscope-assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for lumbar degenerative diseases in comparison with conventional tubular retractor-assisted MIS-TLIF. Methods: Between November 2008 and March 2013, 53 patients with single segment lumbar degenerative diseases were enrolled. According to the different working channel performed, 28 patients were treated by microendoscope-assisted MIS-TLIF (observation group), while the remaining cases received conventional tubular retractor-assisted MIS-TLIF via Wiltse approach (control group). Preoperative baseline data, including age, gender, body mass index, disease etiology, operated level, the ration for requiring bilateral canal decompression, and preoperative visual analogue scale (VAS) socre of low back pain and leg pain, Japanese Orthopedic Association (JOA) score, Oswestry disability index (ODI) score, showed no significant difference between the two groups ( P>0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy time, postoperative analgesic drug dose, postoperation in-bed time, and perioperative complication incidence were recorded respectively and compared between the two groups. Radiographic evaluation of interbody fusion was performed based on Bridwell grading system at 2 years after operation. VAS scores of low back pain and leg pain, JOA score, and ODI score were assessed before operation, at 2 years after operation, and at last follow-up respectively. Surgical outcome satisfaction was assessed by modified MacNab criteria at last follow-up. Results: When compared with those in control group, both intraoperative blood loss and postoperative analgesic drug dose were significantly decreased in observation group ( P0.05). At last follow-up, the results of patients' satisfaction with surgery evaluated by modified MacNab criteria, and the excellent and good rates of the observation group and the control group were 96.4% and 92.0%, respectively, showing no significant difference ( χ2=0.485, P=0.486). Conclusion: The medium and long-term effectiveness of microendoscope-assisted MIS-TLIF are similar to those of conventional tubular retractor-assisted MIS-TLIF for lumbar degenerative diseases. The former operation has the additional advantages in terms of more clear surgical site visually, less intraoperative blood loss, and reduced postoperative analgesic dose, all of which seem more feasible to clinical teaching.
ABSTRACT
Objectives:To analyze the clinical result and the prognostic factors for postoperative patients with foot drop caused by lumbar degenerative disease.Methods:2341 patients who suffered from lumbar degenerative disease and underwent lumbar surgery from January 2011 to January 2016 were reviewed,among which 125 cases suffered from foot drop and caused by lumbar spinal stenosis(LSS) or lumbar disc herniation (LDH).Among the 125 patients,108 cases were enrolled with complete follow-up.All patients underwent modified PLIF and nerve roots decompression.The mean follow-up period was 2.4±1.5 years(range,1.4-5.2 years).Patients whose tibialis anterior(TA) muscle strength recovered to grade 4 or grade 5,the ankle could move freely,with a relative normal gait,could be considered as recovery.The following indexes were included in the single factor analysis by Log-rank test:age,gender,type of lumbar degeneration,duration of palsy,preoperative tibialis anterior strength,physical sensation disorder of affected lower limbs,number of affected limbs,preoperative VAS score,cauda equine syndrome,affected levels and history of trauma.Cox regression analysis was used to analyze the prognostic factors of surgical treatment effect.Results:Among 108 cases of patients with foot drop,59 cases were cured,the recovery rate was about 54.6％.Among them,44 cases were LSS,and 15 cases were cured,the rate was 34.1％;64 cases were LDH,44 cases were cured,the rate was 68.7％.The single factor analysis showed that age,type of lumbar degeneration,duration of palsy,preoperative TA muscle strength and number of affected limbs had significant relation with prognosis (P＜0.05).The Cox regression analysis showed the following indexes were the prognostic factors of foot drop:age,type of lumbar degeneration,duration of palsy and preoperative TA muscle strength(P＜0.05).Conclusions:Age,type of degeneration,duration of palsy and preoperative TA muscle strength are significantly related to the prognosis of foot drop caused by lumbar degenerative disease.Patiets with younger age,shorter duration,stronger TA muscle strength recover better;compared with LSS,foot drop caused by LDH recover better.
ABSTRACT
Objective To evaluate the accuracy and safety of pedicle-scope assisted pedicle screw fixation and percutaneous pedicle screw fixation for treating lumbar degenerative disease(LDD).Methods Thirty cases of LDD treated by mini-invasive transforaminal lumbar interbody fusion(TLIF) under microscope plus percutaneous pedicle screw fixation with fluoroscopy or pedicle-scope of lumbar spine from December 2013 to September 2015 were selected and divide into the percutaneous group and pediclescope group,15 cases in each group.The operative duration,intraoperative blood loss volume,hospital stay and complications were compared between the two groups.The clinical effects were assessed with visual analogue scale(VAS) and Oswestry disability index(ODI).The plain radiography,dynamic radiology and lumbar magnetic resonance imaging(MRI) and computed tomography (CT) were re-examined after operation for assessing the screw location and fusion rate.Results Eighty-four screws were placed in the percutaneous group and 70 screws in the pedicle-scope group.In the percutaneous group and pedicle-scope group,the mean intraoperative blood loss volume,mean operative duration,average times of C-arm fluoroscopy,mean length of hospital stay,mean time of off-bed and complication occurrence rate were measured,and the differences were not statistically significant (P＞ 0.05).In 6-month follow up,the VAS score and ODI score in the two groups were significantly improved compared with before operation(P＜0.01);the VAS score and ODI score were(2.50 ± 1.30) and (50.00-±-3.50) in pediclescope group,(3.00± 1.50) and (58.00 ±4.50) in percutaneous group,respectivehy,and the differences were statistically significant(P＜0.05);the improvement rates of clinical symptoms in the percutaneous group and pedicle-scope group were 73.33 ％ and 80.00 ％ respectively.The imaging reexamination showed that the placed screw location was good and lesion segment fusion was good without screw loosening.The location of 3 screws in the percutaneous group was deviated and adjusted by the second operation.Conclusion The accuracy and safety of pedicle-scope assisted screw placing for treating LDD are higher than those of conventional percutaneous pedicle screw fixation,moreover the operative time is shorter with less intraoperative bleeding.
ABSTRACT
Objective To analyze the causes of surgical errors and complications of lumbar degenerative diseases treated by transforaminal endoscopic spine system(TESSYS),and explore the treatment and prevention measures.Methods From July 2012 to January 2016,the data of 660 patients with lumbar degenerative diseases who treated with TESSYS were analyzed retrospectively,of which 528 patients were lumbar disc herniation with 192 cases of single segment(L4/L5) and 336 cases of multi-segment.Lumbar spinal stenosis in 132 cases,were lateral recess and nerve root canal stenosis.Surgical errors and complications were recorded,and analyzed the reasons and the treatment and preventive measures.Results Intraoperative errors:1 case of sterile film with the dilating catheter went into the surgical area;1 case with wire fracture,and stump retention in vivo;for discography staining,the proportion of mixed solution was not enough,the leakage of excess concentration of methylene blue caused caudal nerve injury in 3 cases;expansion of the intervertebral foramen,the drilling part of the articular process was too deep and too close to the medial wall of the articular process,which caused cutting injury of nerve fiber sheath in 2 cases;after the rupture of the dura mater,the rinse solution was perfused,caused bloating,elevated intracranial pressure,elevated blood pressure and other symptoms of spinal cord hypertension in 3 cases;low dose of local anesthetic into the blood caused toxic reaction in 2 cases;total spinal cord anesthesia with paravertebral nerve root block in 1 case.Postoperative complications:3 cases of nerve root edema;2 cases of free nucleus pulposus tissue;2 cases of local hematoma led to nerve root compression;1 case of intervertebral space infection and 3 cases of local skin neuritis in the puncture area.Conclusion In the process of intervertebral foramen surgery,there are some deficiency on instruments or operating skill.Therefore,rigorous treatment of each link in the perioperative period,is the guarantee of successful surgery.

Conclusion Unilateral small incision under the quadrant assisted MIS?TILF unilateral pedicle nail stick system has obvious advantages in treatment of degenerative lumbar spine disease,as long as we choose to suitable cases and most patients can obtain satisfactory results.
ABSTRACT
STUDY DESIGN: A review of the literature. OBJECTIVES: To discuss how to evaluate, interpret, and utilize measurements of spino-pelvic alignment before and after spinal surgery in patients with lumbar degenerative disease. SUMMARY OF LITERATURE REVIEW: Various spino-pelvic parameters are currently utilized in the evaluation of spinal patients; however, interpretation of these parameters is not easy. MATERIALS AND METHODS: Each spino-pelvic parameter and factors affecting its value, and how to interpret and utilize the spino-pelvic parameters before and after spinal surgery were discussed for patients with lumbar degenerative disease with and without sagittal spinal deformity. RESULTS: Sagittal modifiers in the SRS-Schwab classification including pelvic incidence minus lumbar lordosis (PI-LL), sagittal vertical axis (SVA), and pelvic tilt (PT) are widely accepted in the evaluation of lumbar degenerative disease with sagittal deformity. Surgery for sagittal realignment is meant to restore both the SVA and PT by restoring the LL in reference to the PI. However, patients with an extremely high SVA and PT or those with a high SVA and low PT can end up with postoperative residual malalignment. In patients without deformity, PI-LL mismatch (> 10°) should be highlighted and should be actively corrected by restoring the lordosis of the pathologic segment. CONCLUSIONS: Sagittal modifiers are beneficial for their simplicity and comprehensibility; however, they are insufficient for evaluating sub-regional spinal deformity. Spino-pelvic parameters can be useful for evaluating spinal patients in a clinical setting, but the measurements are greatly affected by confounding factors such as poor patient posture, unqualified testers, and manual measurement techniques.

STUDY DESIGN: Literature review. OBJECTIVES: To present updated information on the relationship of the pelvis and lumbar degenerative disease (LDD) patients and to emphasize the importance of the pelvis in sagittal alignment of LDD patients. SUMMARY OF LITERATURE REVIEW: Although the relationship of the pelvis and sagittal alignment of LDD patients is controversial, many authors have reported a significant impact of the pelvis on LDD sagittal alignment. MATERIALS AND METHODS: The authors identified references through a literature search on the pelvis and LDD and continuous monitoring of the literature during the past 30 years. RESULTS: The pelvis and lumbar levels were related to whole-body sagittal alignment. The pelvis is also closely related to sagittal alignment of LDD patients. Therefore, the entire area should be regarded as a lumbopelvic complex. CONCLUSIONS: We need to consider the concept of a lumbopelvic joint and lumbopelvic lordosis, not a lumbosacral joint and lumbar lordosis. We must also evaluate the lumbopelvic complex to assess whole-body sagittal alignment and dynamic balance.

Objective To explore the clinical efficacy of polyetheretherketone( PEEK) cages and titanium cages combined with pedicle screw fixation operation in treatment of lumbar degenerative disease,and provide reference for clinic. Methods The data of 50 patients with lumbar degenerative disease in our hospital from March 2011 to March 2013 were retrospectively analyzed. All patients were treated with pos-terior decompression,bone graft and transpedicular screw internal fixation,according to the different cages,they were divided into PEEK group and titanium group. The PEEK group with 25 patients used polyetheretherketone cages,and the titanium group with 25 patients used titanium cages. The JOA scores of patient before surgery,1 month,6 months and 1 year after surgery between two groups were recorded and compared. The ROM of fusion levels and adjacent segment of patients before and after operation between two groups were compared. Results There was no statistical significance of difference in JOA score,Oswestry score and fusion rate between two groups(P>0. 05). There were statistical significance of differences intervertebral disc height change between 2 groups(P<0. 05). The ROM of fusion levels and adjacent segment of patients in PEEK group was better than those in titanium group(P<0. 05). Conclusion The polyetheretherketone cages combined with pedicle screw fixation operation have a good effect in the treatment of patients with lumbar degenerative disease,especially in matter of lumbar spinal motion and intervertebral height lost.
ABSTRACT
Objective To analyze the clinical therapeutic effect of lumbar fusion in the treatment of lumbar degenerative diseases in the spine pelvic sagittal balance. Methods From June 2009 to June 2012,the clinical data of 92 cases with lumbar degenerative diseases ac-cepted lumbar spinal fusion operation in our hospital was collected. The contrast lumbar lordosis ( LL) ,lumbar sagittal vertical axis ( SVA) , pelvic incidence angle ( PI) ,sacral inclination angle ( SS) ,pelvic tilt angle ( PT) and other numerical parameters,using the Oswestry disabil-ity index ( ODI) ,visual analogue scale ( VAS) and the Japan Society of Department of orthopedics ( JOA) score were followed up two years after operation,and the postoperative effect was evaluated. Results The spinal pelvic parameters SVA,LL,SS and PT after surgery were changed obviously,and the difference was statistically significant(P<0. 05). The postoperative follow-up of VAS,ODI and JOA score were better than that of preoperation,the difference was significant(P<0. 05). Conclusion Lumbar fusion operation can restore lumbar lordosis, to maintain the spine pelvic sagittal balance and improve the effect of operation,and have positive significance to improve the postoperative symptoms.
