ABSTRACT

Abstract Objectives To evaluate the correlation between radiologic changes (Pfirrmann and Modic) and radicular pain intensity in patients who underwent transforaminal endoscopic surgery for lumbar disc herniation. Methods Series of cases with 39 patients, 50 intervertebral discs in preoperative evaluation from January 29, 2018 to August 28, 2019 in an endoscopic spine surgery service. Demographic data, surgical indication, operative details and complications were obtained from medical records. The patients were divided into three groups based on the Modic classification (Modic absence, Modic 1 and Modic 2) and into two groups considering the Pfirrmann classification (Pfirrmann IV and Pfirrmann V). Data were processed in IBM SPSS Statistics for Windows, Version 22.0 (IBM Corp., Armonk, NY, USA), with a significance level of p< 0,05. Results There was no difference between genders; age: 50,36 ± 15,05 years old; disease level: L2-L3 1 (2%), L3-L4 2 (4%), L4-L5 9 (18%), L5-S1 8 (16%), L3-L4 + L4-L5 4 (8%), and L4-L5 + L5-S1 26 (52%); location: right foraminal 7 (14%), left foraminal 15 (30%), central 9 (18%) and diffuse 19 (38%); radicular pain: left 25 (50%), right 11 (22%), and bilateral 14 (28%); preoperative visual analogue scale (VAS): 9,5 ± 0,91, postoperative: 2,5 ± 1,79; surgery duration: 100 ± 31,36 minutes; and follow-up: 8,4 ± 6,7 months. Less postoperative sciatica was registered in the Modic 2 versus Modic 1 group (p< 0,05). There was no difference in the postoperative radicular pain between the Pfirrmann groups (IV versus V). Conclusion Although there is no clinical difference between the groups, in advanced stages of disc degeneration, endoscopic transforaminal discectomy proved to be effective in diminishing radicular pain in patients with lumbar disc herniation.

ABSTRACT

ABSTRACT Objective To describe the technical specificities and feasibility of simulation of minimally invasive spine surgery in live pigs, as well as similarities and differences in comparison to surgery in humans. Methods A total of 22 Large White class swine models, weighing between 60 and 80kg, were submitted to surgical simulations, performed during theoretical-practical courses for training surgical techniques (microsurgical and endoscopic lumbar decompression; percutaneous pedicular instrumentation; lateral access to the thoracic spine, and anterior and retroperitoneal to the lumbar spine, and management of complications) by 86 spine surgeons. For each surgical technique, porcine anatomy (similarities and differences in relation to human anatomy), access route, and dimensions of the instruments and implants used were evaluated. Thus, the authors describe the feasibility of each operative simulation, as well as suggestions to optimize training. Study results are descriptive, with figures and drawings. Results Neural decompression surgeries (microsurgeries and endoscopic) and pedicular instrumentation presented higher similarities to surgery on humans. On the other hand, intradiscal procedures had limitations due to the narrow disc space in swines. We were able to simulate situations of surgical trauma in surgical complication scenarios, such as cerebrospinal fluid fistulas and excessive bleeding, with comparable realism to surgery on humans. Conclusion A porcine model for simulation of minimally invasive spinal surgical techniques had similarities with surgery on humans, and is therefore feasible for surgeon training.

ABSTRACT

SUMMARY OBJECTIVE: This study aims to investigate the value of magnetic resonance combined with dual-source spectral computed tomography in improving the clinical diagnosis and treatment efficiency of lumbar disk herniation. METHODS: Two hundred patients with lumbar disk herniation were enrolled. Magnetic resonance and dual-source spectral computed tomography were used to perform the diagnosis. The treatment efficiency and effectiveness of different diagnostic methods were determined. Results: Eighty cases of lumbar disk herniation, 40 cases of prolapse, 33 cases of bulge, 27 cases of sequestration, and 20 cases of nodules were diagnosed based on pathologic evaluation. magnetic resonance detected lumbar disk herniation in 172 cases, with a detection rate of 86.00%. Dual-source spectral computed tomography detected 171 cases, with a detection rate of 85.50%. Magnetic resonance combined with dual-source spectral computed tomography detected 195 cases, with a detection rate of 97.50%. There was no significant difference between magnetic resonance and dual-source spectral computed tomography (p>0.05), but compared with the combined detection, there was a significant difference (p<0.05). One hundred and two cases of calcification, 83 cases of spinal cord deformity, 70 cases of intervertebral disk degeneration, 121 cases of intervertebral disk gas, 85 cases of dural sac compression, and 78 cases of nerve root compression were surgically demonstrated. The detection rate of diagnostic signs based on imaging by magnetic resonance or dual-source spectral computed tomography alone was lower than that of combined detection (p<0.05). Conclusion: Magnetic resonance combined with dual-source spectral computed tomography can improve the diagnosis and treatment efficiency and effectiveness of lumbar disk herniation.

ABSTRACT

Abstract Objective To virtually prototype a device for external circular fixation of long bone fractures with controlled dynamization made of two different materials and predict their mechanical behavior by using the finite element analysis (FEA) method. Method A software was used for 3D modeling two metal parts closely attached by a sliding dovetail joint and a high-density silicone damper. Distinctive FEAs were simulated by considering two different materials (stainless steel or titanium), modes (locked or dynamized) and loading conditions (static/point or dynamic/0.5 sec) with uniform 150 kg axial load on top of the device. Results The finite elements (FEs) model presented 81,872 nodes and 45,922 elements. Considering stainless steel, the maximum stress peak (140.98 MPa) was reached with the device locked under static loading, while the greatest displacement (2.415 × 10−3 mm) was observed with the device locked and under dynamic loading. Regarding titanium, the device presented the maximum stress peak (141.45 MPa) under static loading and with the device locked, while the greatest displacement (3.975 × 10−3 mm) was found with the device locked and under dynamic loading. Conclusion The prototyped device played the role of stress support with acceptable deformation in both locked and dynamized modes and may be fabricated with both stainless steel and titanium.

ABSTRACT

Abstract Populational aging increases the incidence of musculoskeletal degenerative processes, such as adult scoliosis (AS). Adult scoliosis is defined as a spinal deformity in the coronal plane with a Cobb angle > 10º. Adult scoliosis may be iatrogenic or result from a degenerative process (scoliosis de novo) or a pre-existing scoliosis. Adult scoliosis is a potentially limiting condition that affects a heterogeneous group of patients. Clinical treatment proved to be ineffective and surgery is often indicated. The present paper reviews AS pathophysiology, clinical presentation and diagnosis, in addition to surgical indications and the main techniques currently used.


Resumo O envelhecimento da população aumenta a incidência dos processos degenerativos osteomusculares, como a escoliose do adulto (EA). A EA é definida como uma deformidade da coluna no plano coronal com ângulo de Cobb > 10º e pode ocorrer devido a um processo degenerativo (escoliose de novo), evolução de uma escoliose pré-existente ou de forma iatrogênica. A EA é uma doença potencialmente limitante que acomete um grupo heterogêneo de pacientes. O tratamento clínico se mostrou pouco efetivo e a indicação cirúrgica é frequente. No presente artigo, é apresentada uma revisão sobre a fisiopatologia, a manifestação clínica e o diagnóstico da EA. Também são apresentadas as indicações cirúrgicas e as principais técnicas utilizadas atualmente.

ABSTRACT

Spinal fusion is a standard operation for treating moderate and severe intervertebral disc diseases. In recent years, the proportion of three-dimensional printing interbody fusion cage in spinal fusion surgery has gradually increased. In this paper, the research progress of molding technology and materials used in three-dimensional printing interbody fusion cage at present is summarized. Then, according to structure layout, three-dimensional printing interbody fusion cages are classified into five types: solid-porous-solid (SPS) type, solid-porous-frame (SPF) type, frame-porous-frame (FPF) type, whole porous cage (WPC) type and others. The optimization process of three-dimensional printing interbody fusion cage and the advantages and disadvantages of each type are analyzed and summarized in depth. The clinical application of various types of 3D printed interbody fusion cage was introduced and summarized later. Lastly, combined with the latest research progress and achievements, the future research direction of three-dimensional printing interbody fusion cage in molding technology, application materials and coating materials is prospected in order to provide some reference for scholars engaged in interbody fusion cage research and application.

ABSTRACT

OBJECTIVE@#To investigate the expression and clinical significance of receptor interacting protein serine-threonine kinases 1 (RIPK1) in the nucleus pulposus of patients with lumbar disc herniation (LDH).@*METHODS@#Nucleus pulposus tissue specimens of 40 patients with LDH patients underwent surgical treatment from January 2016 to January 2018 as the case group, and nucleus pulposus tissue specimens of 30 patients with lumbar spine fracture underwent surgical treatment at the same time as the control group. The expression of RIPK1 mRNA and protein of receptor interaction were detected by polymerase chain reaction (PCR) and Western blot, respectively. The expression of RIPK1 protein in the nucleus pulposus were detected by immunohistochemical staining. The concentrations of RIPK1 and tumor necrosis factor-α (TNF-α) in nucleus pulposus were detected by ELISA method. The relationship between the concentrations of RIPK1, TNF-α in nucleus pulposus and the Pearce grade of LDH patients was analyzed by one-way ANOVA. The correlation between RIPK1 and TNF-α was analyzed by Pearson.@*RESULTS@#RIPK1 was weakly positively expressed in nucleus pulposus of control group, and RIPK1 protein was positively or strongly positively expressed in case group. The expression of RIPK1 mRNA in nucleus pulposus of case group was higher than that of control group (@*CONCLUSION@#The expression levels of RIPK1 mRNA and protein in the intervertebral disc tissues of LDH patients are higher than those of normal intervertebral disc tissues, and increased with the increase of Pearce grade, which may be an important factor involved in LDH inflammatory disease.

Complete imaging follow-up data were obtained from 24 patients. There were 15 males and 20 females, aged from 39 to 70(55.57±7.73) years old. The amount of bleeding was for 20 to 100 (40.29±18.39) ml, and the hospitalstay was for 4 to 28(11.03±4.63) days, and the follow-up time was(12.97±1.36) months. Clinical outcomes were assessed by the Tanaka Yasushi cervical spondylitis symptom scale 20 score (YT20), and Japanese Orthopaedic Association (JOA) score. The occurrence of heterotopic ossification after Hybrid surgery was evaluated by X-ray according to McAfee standard one year after operation. Patients with or without heterotopic ossificationwere divided into two groups and their clinical effects were compared.@*RESULTS@#At the final follow up, the mean YT20 score and JOA score were significantly higher than those before operation (P <0.05), and the average improvement rate of JOA was (70.66 ±0.44)%. One year after operation, the heterotopic ossification occurred in 10 of 24 segments, with incidence of 41.70%(10/24), including 29.20% in gradeⅠand 12.50% in gradeⅡ. The results of clinical efficacy comparison between patients with and without heterotopic ossification were as follows:there was no significant difference in JOA score before and after operation (@*CONCLUSION@#The short-term clinical effect of Hybrid surgery is satisfactory for cervical degenerative diseases, and the cause of heterotopic ossification still needs tobe further explored.

ABSTRACT

OBJECTIVE@#To compare the clinical effecty of Wiltse approach combined with contralateral transforaminal lumbar interbody fusion (TLIF) and traditional TLIF in the treatment of lumbar disc herniation and its affect on injury of multifidus muscle.@*METHODS@#From June 2014 to September 2017, 90 patients with lumbar disc herniation combined with lumbar spine instability were divided into two groups (Wiltse approach group and traditional group) depend on the procedure of operation. Wiltse approach group was treated with Wiltse approach screw placement in one side combined with contralateral TLIF. There were 50 patients in Wiltse approach group, including 36 males and 14 females, aged 45 to 72 yearswith an average of (60.4± 3.1) years. The traditional group was treated with traditional TLIF operation. There were 40 patients in the traditional group, including 25 males and 15 females, aged 45 to 74 years with an average of (62.1±3.4) years. The operative time, intraoperative blood loss, accuracy of screw implantation, postoperative drainage volume and drainage tube removal time were recorded in two groups. Visual analogue scale (VAS) and Oswestry Disability Index (ODI)were observed before and 12 months after operation. All patients underwent CT examination preoperative and 12 months postoperative, and the CT values of bilateral multifidus muscle were measured.@*RESULTS@#All the patients were followed up, 40 patients in traditional group were 12 to 18 months with an average of (15.3±4.3) months; and 50 patients in Wiltse approach group were 13 to 24 months with an average of (16.5± 4.1) months. There were no statistically significant differences in operative time and intraoperative blood loss between two groups (@*CONCLUSION@#Compared with traditional surgical procedures, the Wiltse approach nail placement combined with contralateral TLIF has the advantage of accurate nail placement, reducing multifidus muscle damage, and reducing the incidence of postoperative intractable low back pain.

ABSTRACT

OBJECTIVE@#To investigate the biomechanical affect of percutaneous transforaminal endoscopic discectomy(PTED) on adjacent segments with different degrees of degeneration and related risk of adjacent segment diseases (ASD) caused by this operation.@*METHODS@#A healthy male adult volunteer was selected, and the lumbosacral vertebra image data was obtained by CT scan, and the external contour of the bone structure was reconstructed. On this basis, the external contour of the bone structure was fitted by using the smooth curve in 3D-CAD software, and the complete three-dimensional finite element modelof the non degenerate L@*RESULTS@#In the finite element model without adjacent segmental disc degeneration, the annulus fibrosus von Mises stress and intradiscal pressure of the PTED model showed only a slight increase under most stress conditions, and a slight decrease in a few conditions, and there was no significant change trend before and after surgery. In the original degenerated adjacent segment disc model, the biomechanical indicators related to disc degeneration in the pre- and post-PTED model showed significant deterioration, leading to an increased risk of potential adjacent spondylopathy.@*CONCLUSION@#PTED surgery will not lead to the significant deterioration of postoperative biomechanical environment of non-degeneration adjacent intervertebral discs, and the original degeneration of adjacent intervertebral discs is a important risk factor for ASD.

ABSTRACT

OBJECTIVE@#To observe the therapeutic effect of electroacupuncture on lumbar disc herniation (LDH) with different multifidus fatty infiltration rates.@*METHODS@#A total of 108 eligible LDH patients received MRI test before treatment and the multifidus fatty infiltration rate (FI) was measured. According to theresults, they were divided to group A (FI20%), 36 cases in each one. EA was provided in all of the groups. The selected acupoints were Jiaji (EX-B 2) from L@*RESULTS@#Compared with before treatment, ODI score was reduced (@*CONCLUSION@#Electroacupuncture relieves pain and improves physical and psychological health of LDH patients. Multifidus fatty infiltration rate is probably one of the factors to influence the therapeutic effect of electroacupuncture.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of single acupoint [Yaotu (extra)] electroacupuncture (EA) therapy on lumbar intervertebral disc herniation (LIDH) and its promotion and application in community medical institutions.@*METHODS@#This research adopted a three-level promotion model, and used multi-center collaboration topics as a platform. A total of 240 patients with LIDH were divided into a group A (top three hospital, 80 cases, 3 cases dropped off), a group B (secondary hospital, 80 cases, 8 cases dropped off), and a group C (community health center, 80 cases, 7 cases dropped off). All groups were treated with EA at a single acupoint [Yaotu (extra)] under the guidance of a unified experimental protocol. The EA was given 60 min each time and performed 3 times a week for a total of 2 weeks. The changes of visual analogue scale (VAS) scores of three groups before and after each treatment were compared, and the clinical efficacy was evaluated.@*RESULTS@#Compared with before each treatment, the VAS scores of three groups after each treatment decreased (@*CONCLUSION@#The single acupoint EA therapy has a significant effect in the treatment of LIDH, can quickly relieve the pain symptoms, and has the characteristics of simple operation and easy control, suitable for promotion and application in primary hospitals.

ABSTRACT

OBJECTIVE@#To observe the analgesic effect of lever positioning manipulation combined with pulsed electric field on patients with lumbar disc herniation and the influence on serum IL-1β and TNF-α.@*METHODS@#From January 2018 to March 2019, 58 patients with lumbar disc herniation were included in the study, which were randomly divided into observation group and control group by digital table method. Observation group of 29 cases, including 16 males and 13 females, aged (38.03±11.29) years old, were treated with lever positioning manipulation combined with pulsed electric field. The 29 cases in control group, including 17 males and 12 females, aged (38.21±9.16) years old, were treated with pulsed electric field. Both groups of patients were treated 3 times a week, once every other day, 3 times as a course of treatment. After 2 courses of treatment, the two groups of patients were scored before and after treatment by the numeric rating scales (NRS);at the same time, the serum levels of IL-1β and TNF-α were measured before and after treatment.@*RESULTS@#The NRS scores of observation group and control group were 4.21±1.76, 4.66±1.61 before treatment, and 1.28±0.84, 2.10±1.35 after treatment, respectively. The NRS scores of the observation group after treatment was significantly lower than that of the control group (@*CONCLUSION@#The lever positioning manipulation combined with pulsed electric field has a good analgesic effect on patients with lumbar disc herniation, and it has a significant impact on the patient's serum IL-1β and TNF-α concentration, which can be used as a clinical guide. However, the synergistic effect of lever positioning technique combined with pulsed electric field and guidelines for clinical treatment need further research.
