Simultaneous spinal stenosis across all three regions of the spine is an uncommon condition that requires proper clinical and imaging assessment. There are currently no established guidelines for its diagnosis and treatment. The objective of this paper is to describe, based on a case report, the clinical presentation, treatment, and progression of triple stenosis in a patient and compare it with available evidence through a narrative literature review. A 69-year-old woman presented with progressive paraparesis associated with right sciatica and positive signs of upper motor neuron involvement. Imaging confirmed triple stenosis: cervical, thoracic, and lumbar. She underwent thoracic decompression and tumor resection, as well as conservative treatment for cervical and lumbar stenoses, and showed favorable progress one year after surgery. Symptomatic triple-region spinal stenosis is an uncommon condition. Proper clinical and radiological assessments will enable an accurate diagnosis with appropriate and timely intervention.

INTRODUCTION: Neurogenic claudication (NC) is the classic clinical presentation of patients with Lumbar Spinal Stenosis (LSS). These patients may or may not present with symptoms of leg pain and difficulty walking. These symptoms are exacerbated while walking and standing and are eased by sitting or bending forward. METHOD: Patients with LSS, having a lumbar canal diameter of ≤12mm, were recruited from a recognized Tertiary care hospital. Each subject's demographic characteristics and anthropometrics were noted, and the testing procedure was explained. The canal diameter was documented with the help of an MRI report. A self-paced walking test was used to assess the walking distance. STATISTICAL ANALYSIS: Depending on the normality of the data, the Pearson correlation coefficient (r) was used to find the correlation between canal diameter at different lumbar levels and walking distance in patients with LSS. RESULT: Pearson correlation coefficient (r) determined a fair positive correlation (r = 0.29) between lumbar canal diameter and walking distance. Stepwise multiple regression analysis was done, and a prediction equation was found for different levels of canal stenosis. CONCLUSION: Findings of our present study suggest a fair positive correlation between walking distance and canal diameter at L5-S1. This study may also be useful in predicting the approximate canal diameter by estimating the walking distance of the patient with symptoms of LSS and vice-versa.
INTRODUÇÃO: A claudicação neurogênica (CN) é a apresentação clínica clássica de pacientes com Estenose Espinhal Lombar (EEL). Esses pacientes podem ou não apresentar sintomas de dor nas pernas e dificuldade para caminhar. Esses sintomas são exacerbados ao caminhar e ficar em pé e são aliviados ao sentar ou inclinar-se para a frente. MÉTODO: Pacientes com EEL, com diâmetro do canal lombar ≤12mm, foram recrutados em um hospital terciário reconhecido. As características demográficas e antropométricas de cada sujeito foram anotadas e o procedimento do teste foi explicado. O diâmetro do canal foi documentado com a ajuda de um relatório de ressonância magnética. Um teste de caminhada individualizado foi usado para avaliar a distância percorrida. ANÁLISE ESTATÍSTICA: Dependendo da normalidade dos dados, o coeficiente de correlação de Pearson (r) foi usado para encontrar a correlação entre o diâmetro do canal em diferentes níveis lombares e a distância percorrida em pacientes com EEL. RESULTADO: O coeficiente de correlação de Pearson (r) determinou uma correlação positiva razoável (r = 0,29) entre o diâmetro do canal lombar e a distância percorrida. Análise de regressão múltipla stepwise foi feita, e uma equação de predição foi encontrada para diferentes níveis de estenose do canal. CONCLUSÃO: Os achados de nosso estudo sugerem uma correlação positiva razoável entre a distância percorrida e o diâmetro do canal em L5-S1. Este estudo também pode ser útil para prever o diâmetro aproximado do canal, estimando a distância percorrida pelo paciente com sintomas de EEL e vice-versa.

OBJECTIVE@#To analyze the early effectiveness of unilateral biportal endoscopy (UBE) laminectomy in the treatment of two-level lumbar spinal stenosis (LSS).@*METHODS@#The clinical data of 98 patients with two-level LSS treated with UBE between September 2020 and December 2021 were retrospectively analyzed. There were 53 males and 45 females with an average age of 59.9 years (range, 32-79 years). Among them, there were 56 cases of mixed spinal stenosis, 23 cases of central spinal canal stenosis, and 19 cases of nerve root canal stenosis. The duration of symptoms was 1.5- 10 years, with an average of 5.4 years. The operative segments were L 2, 3 and L 3, 4 in 2 cases, L 3, 4 and L 4, 5 in 29 cases, L 4, 5 and L 5, S 1 in 67 cases. All patients had different degrees of low back pain, among of which 76 cases were with unilateral lower extremity symptoms and 22 cases were with bilateral lower extremity symptoms. There were 29 cases of bilateral decompression in both segments, 63 cases of unilateral decompression in both segments, and 6 cases of unilateral decompression and bilateral decompression of each segment. The operation time, intraoperative blood loss, total incision length, hospitalization stay, ambulation time, and related complications were recorded. Visual analogue scale (VAS) score was used to assess the low back and leg pain before operation and at 3 days, 3 months after operation, and at last follow-up. The Oswestry disability index (ODI) was used to evaluate the functional recovery of lumbar spine before operation and at 3 months and last follow-up after operation. Modified MacNab criteria was used to evaluate clinical outcomes at last follow-up. Imaging examinations were performed before and after operation to measure the preservation rate of articular process, modified Pfirrmann scale, disc height (DH), lumbar lordosis angle (LLA), and cross-sectional area of the canal (CAC), and the CAC improvement rate was calculated.@*RESULTS@#All patients underwent surgery successfully. The operation time was (106.7±25.1) minutes, the intraoperative blood loss was (67.7±14.2) mL, and the total incision length was (3.2±0.4) cm. The hospitalization stay was 8 (7, 9) days, and the ambulation time was 3 (3, 4) days. All the wounds healed by first intention. Dural tear occurred in 1 case during operation, and mild headache occurred in 1 case after operation. All patients were followed up 13-28 months with an average of 19.3 months, and there was no recurrence or reoperation during the follow-up. At last follow-up, the preservation rate of articular process was 84.7%±7.3%. The modified Pfirrmann scale and DH were significantly different from those before operation ( P<0.05), while the LLA was not significantly different from that before operation ( P=0.050). The CAC significantly improved ( P<0.05), and the CAC improvement rate was 108.1%±17.8%. The VAS scores of low back pain and leg pain and ODI at each time point after operation significantly improved when compared with those before operation, and the differences between each time points were significant ( P<0.05). According to the modified MacNab criteria, 63 cases were excellent, 25 cases were good, and 10 cases were fair, with an excellent and good rate of 89.8%.@*CONCLUSION@#UBE laminectomy is a safe and effective technique with little trauma and fast recovery for two-level LSS and the early effectiveness is satisfactory.

OBJECTIVE@#To review the application and progress of different minimally invasive spinal decompression in the treatment of lumbar spinal stenosis (LSS).@*METHODS@#The domestic and foreign literature on the application of different minimally invasive spinal decompression in the treatment of LSS was extensively reviewed, and the advantages, disadvantages, and complications of different surgical methods were summarized.@*RESULTS@#At present, minimally invasive spinal decompression mainly includes microscopic bilateral decompression, microendoscopic decompression, percutaneous endoscopic lumbar decompression, unilateral biportal endoscopy, and so on. Compared with traditional open surgery, different minimally invasive spinal decompression techniques can reduce the operation time, intraoperative blood loss, and postoperative pain of patients, thereby reducing hospital stay and saving treatment costs.@*CONCLUSION@#The indications of different minimally invasive spinal decompression are different, but there are certain advantages and disadvantages. When patients have clear surgical indications, individualized treatment plans should be formulated according to the symptoms and signs of patients, combined with imaging manifestations.

OBJECTIVE@#To compare the efficacy and muscle injury imaging between oblique lateral lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of single-segment degenerative lumbar spinal stenosis.@*METHODS@#The clinical data of 60 patients with single-segment degenerative lumbar spinal stenosis who underwent surgical treatment from January 2018 to October 2019 was retrospectively analyzed. The patients were divided into OLIF groups and TLIF group according to different surgical methods. The 30 patients in the OLIF group were treated with OLIF plus posterior intermuscular screw rod internal fixation. There were 13 males and 17 females, aged from 52 to 74 years old with an average of (62.6±8.3) years old. And 30 patients in the TLIF group were treated with TLIF via the left approach. There were 14 males and 16 females, aged from 50 to 81 years old with an average of (61.7±10.4) years old. General data including operative time, intraoperative blood loss, postoperative drainage volume, and complications were recorded for both groups. Radiologic data including disc height (DH), the left psoas major muscle, multifidus muscle, longissimus muscle area, T2-weighted image hyperintensity changes and interbody fusion or nonfusion were observed. Laboratory parameters including creatine kinase (CK) values on postoperative 1st and 5th days were analyzed. Visual analogue scale(VAS) and Oswestry disability index(ODI) were used to assess clinical efficacy.@*RESULTS@#There was no significant difference in the operative time between two groups(P>0.05). The OLIF group had significantly less intraoperative blood loss and postoperative drainage volume compared to the TLIF group(P<0.01). The OLIF group also had DH better recovery compared to the TLIF group (P<0.05). There were no significant differences in left psoas major muscle area and the hyperintensity degree before and after the operation in the OLIF group (P>0.05). Postoperativly, the area of the left multifidus muscle and longissimus muscle, as well as the mean of the left multifidus muscle and longissimus muscle in the OLIF group, were lower than those in the TLIF group (P<0.05) .On the 1st day and the 5th day after operation, CK level in the OLIF group was lower than that in the TLIF group(P<0.05). On the 3rd day after operation, the VAS of low back pain and leg pain in the OLIF group were lower than those in the TLIF group (P<0.05). There were no significant differences in the ODI of postoperative 12 months, low back and leg pain VAS at 3, 6, 12 months between the two groups(P>0.05). In the OLIF group, 1 case of left lower extremity skin temperature increased after the operation, and the sympathetic chain was considered to be injured during the operation, and 2 cases of left thigh anterior numbness occurred, which was considered to be related to psoas major muscle stretch, resulting in a complication rate of 10% (3/30). In the TLIF group, one patient had limited ankle dorsiflexion, which was related to nerve root traction, two patients had cerebrospinal fluid leakage, and the dural sac was torn during the operation, and one patient had incision fat liquefaction, which was related to paraspinal muscle dissection injury, resulting in a complication rate of 13% (4/30). All patients achieved interbody fusion without cage collapse during the 6- month follow-up.@*CONCLUSION@#Both OLIF and TLIF are effective in the treatment of single-segment degenerative lumbar spinal stenosis. However, OLIF surgery has obviously advantages, including less intraoperative blood loss, less postoperative pain, and good recovery of intervertebral space height. From the changes in laboratory indexes of CK and the comparison of the left psoas major muscle, multifidus muscle, longissimus muscle area, and high signal intensity of T2 image on imaging, it can be seen that the degree of muscle damage and interference of OLIF surgery is lower than that of TLIF.

OBJECTIVE@#To compare the effectiveness between unilateral biportal endoscopic lumbar interbody fusion (ULIF) and endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) in treatment of lumbar spinal stenosis combined with intervertebral disc herniation.@*METHODS@#A clinical data of 64 patients with lumbar spinal stenosis and intervertebral disc herniation, who were admitted between April 2020 and November 2021 and met the selection criteria, was retrospectively analyzed. Among them, 30 patients were treated with ULIF (ULIF group) and 34 patients with Endo-TLIF (Endo-TLIF group). There was no significant difference in baseline data such as gender, age, disease duration, lesion segment, preoperative visual analogue scale (VAS) score of low back pain and leg pain, Oswestry disability index (ODI), spinal canal area, and intervertebral space height between the two groups ( P>0.05). The operation time, intraoperative blood loss, hospital stays, and postoperative complications were compared between the two groups, as well as the VAS scores of low back pain and leg pain, ODI, and imaging measurement indicators (spinal canal area, intervertebral bone graft area, intervertebral space height, and degree of intervertebral fusion according to modified Brantigan score).@*RESULTS@#Compared with the Endo-TLIF group, the ULIF group had shorter operation time, but had more intraoperative blood loss and longer hospital stays, with significant differences ( P<0.05). The cerebrospinal fluid leakage occurred in 2 cases of Endo-TLIF group and 1 case of ULIF group, and no other complication occurred. There was no significant difference in the incidence of complications between the two groups ( P>0.05). All patients in the two groups were followed up 12 months. The VAS scores of lower back pain and leg pain and ODI in the two groups significantly improved when compared with those before operation ( P<0.05), and there was no significant difference between different time points after operation ( P>0.05). And there was no significant difference between the two groups at each time point after operation ( P>0.05). Imaging examination showed that there was no significant difference between the two groups in the change of spinal canal area, the change of intervertebral space height, and intervertebral fusion rate at 6 and 12 months ( P>0.05). The intervertebral bone graft area in the ULIF group was significantly larger than that in the Endo-TLIF group ( P<0.05).@*CONCLUSION@#For the patients with lumbar spinal stenosis combined with intervertebral disc herniation, ULIF not only achieves similar effectiveness as Endo-TLIF, but also has advantages such as higher decompression efficiency, flexible surgical instrument operation, more thorough intraoperative intervertebral space management, and shorter operation time.

OBJECTIVE@#To investigate the clinical significance and screen the risk factors of redundant nerve roots(RNRs) in patients with lumbar spinal stenosis.@*METHODS@#The clinical data of 196 patients with lumbar spinal stenosis in the department of Spinal Surgery, Yijishan Hospital, Wannan Medical College from April 1, 2015 to November 30, 2020 were retrospectively analyzed. All patients were divided into RNRs positive group and RNRs negative group according to the presence of RNRs. The differences in general clinical data, imaging parameters, visual analogue scale(VAS), Oswestry disability index(ODI), and other indicators between the two groups were compared. The risk factors which are highly correlated with RNRs were screened by binary Logistic regression analysis.@*RESULTS@#There were 59 cases in the RNRs positive group, with an occurrence rate of 29.95% (59/137), and 137 cases in the RNRs negative group. The incidence rate of RNRs in 196 patients with lumbar spinal stenosis was 30.10% (59/196). VAS and ODI scores of patients in the two groups were statistically significant (P<0.05), and clinical symptoms of patients in the RNRs positive group were more severe than those in the RNRs negative group. There were significant differences in age, number of stenosis segments, average area of lumbar dural sac, area of the narrowest segment and the narrowest segment(P<0.05). Binary logistic regression analysis showed that the number of stenosis segments, the average median sagittal diameter of spinal canal, and the average area of dural sac in lumbar intervertebral space were correlated with the generation of RNRs (P<0.05). The regression coefficient of the number of stenosis segments was -1.115, the regression coefficient of the median sagittal diameter of the spinal canal was -1.707, and the regression coefficient of the mean dural sac area of the lumbar intervertebral space was 7.556.@*CONCLUSION@#The clinical symptoms of patients with lumbar spinal stenosis accompanied by RNRs are more severe than those without them. The number of narrow segments, median sagittal diameter of the spinal canal, and the area of the lumbar intervertebral dural sac are the high-risk factors for RNRs, with the area of the lumbar intervertebral dural sac has the highest correlation.

There were 32 males and 16 females, aged from 60 to 83 years old with an average of (72.9±6.5) years, course of disease ranged from 5 to 16 years with an average of (8.0±2.8) years. The patients were divided into observation group and control group according to surgical approaches. There were 28 cases in observation group, underwent Endo-LOVE surgery;and 20 cases in control group, underwent full endoscopic foraminal approach discectomy. The operation time, intraoperative blood loss, hospitalization day and complications were observed between two groups. Visual analgue scale (VAS), Japanese Orthopaedic Association(JOA), Oswestry Disability Index(ODI), lateral crypt angle were compared between two groups. And clinical effects were evaluated by modified Macnab standard.@*RESULTS@#There was no significant difference in follow-up and operation time between two groups (P>0.05). Intraoperative blood loss was from 5 to 15 ml with an average of (8.4±3.6) ml in observation group and 5 to 25 ml with an average of (11.5±5.4) ml in control group. The hospitalization day was from 5 to 8 days with an average of (6.0±1.0) days in observation group and 6 to 9 days with an average (7.2±1.1) days in control group. Intraoperative blood loss and hospitalization day were significantly lower in observation group(P<0.05). There were no serious complications in both groups. The VAS, JOA scores, and ODI at 3-month and final follow-up were significantly improved in both groups (P<0.05), and observation group was significantly better than control group (P<0.05). The skeletal lateral crypt angle and soft lateral crypt angle were significantly greater than the preoperative angle at 3 days postoperatively(P<0.05), and observation group was significantly better than control group(P<0.05). At the final follow-up, the modified Macnab criteria was used to assess clinical efficacy, in observation group, 22 patients obtained excellent results, 5 good and 1 fair;while 11 excellent, 4 good and 5 fair in control group;the clinical efficacy of observation group was significantly better than that of control group(P<0.05).@*CONCLUSION@#Both surgical methods are performed under direct vision, with high safety and good clinical efficacy. However, Endo-LOVE enlarged the lateral crypt more fully.

OBJECTIVE@#To investigate the clinical efficacy and safety of percutaneous foraminal endoscopy in the treatment of lumbar lateral recess stenosis in elderly.@*METHODS@#The clinical data of 31 elderly patients with lumbar lateral recess stenosis treated by percutaneous foraminal endoscopic decompression from March 2018 to August 2019 were retrospectively analyzed. Including 16 males and 15 females, aged from 65 to 81 years with an average of (71.13±5.20) years, the course of disease ranged from 3 months to 7 years with an average of (14.36±6.52) months. Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to assess clinical symptom and functional status before operation and 1, 6, 12 months after operation. At the final follow-up, the modified Macnab standard was used to evaluate clinical efficacy.@*RESULTS@#All patients were completed the operation successfully. The operation time was from 75 to 120 min with an average of (97.84±11.22 ) min. All 31 patients were followed up from 12 to 28 months with an average of (17.29±5.56) months. Postoperative lumbago-leg pain VAS and ODI were significantly improved at 1, 6, and 12 months(P<0.01). At the final follow-up, according to the modified Macnab standard to evaluate the effect, 23 got excellent results, 5 good, 3 fair. One patient had severe adhesions between peripheral tissues and nerve root, and postoperative sensory abnormalities in the lower extremities were treated conservatively with traditional Chinese medicine and neurotrophic drugs, which recovered at 2 weeks after surgery. No complications such as nerve root injury and infection occurred.@*CONCLUSION@#The intervertebral foraminal endoscopy technique, which is performed under local anesthesia for a short period of operation, ensures adequate decompression while minimizing complications, and is a safe and effective surgical procedure for elderly patients with lumbar lateral recess stenosis.

OBJECTIVE@#To investigate early clinical efficacy of unilateral biportal endoscopy technique for the treatment of lumbar postoperative adjacent segmental diseases.@*METHODS@#Fourteen patients with lumbar postoperative adjacent segmental diseases were treated with unilateral biportal endoscopy technique from June 2019 to June 2020. Among them, there were 9 males and 5 females, aged from 52 to 73 years old, and the interval between primary and revision operations ranged from 19 to 64 months. Adjacent segmental degeneration occurred after lumbar fusion in 10 patients and after lumbar nonfusion fixation in 4 patients. All the patients received unilateral biportal endoscopy assisted posterior unilateral lamina decompression or unilateral approach to the contralateral decompression. The operation time, postoperative hospital stay and complications were observed. The visual analogue scale (VAS) of low back pain and leg pain, Oswestry Disability Index (ODI), modified Japanese Orthopaedic Association (mJOA) score were recorded before operation and at 3 days, 3 months, and 6 months after operation.@*RESULTS@#All procedures were successfully completed. Surgical duration ranged from 32 to 151 min. Postoperative CT showed adequate decompression and preservation of most joints. Out of bed walking 1 to 3 days after surgery, postoperative hospital stay was 1 to 8 days, and postoperative follow-up was 6 to 11 months. All 14 patients returned to normal life within 3 weeks after surgery, and VAS, ODI, and mJOA scores improved significantly at 3 days and 3, 6 months after surgery. One patient occurred cerebrospinal fluid leak after operation, received local compression suture, and the wound healed after conservative treatment. One patient occurred postoperative cauda equina neurologic deficit, which was gradually recovered about 1 month after rehabilitation therapy. One patients advented transient pain of lower limbs after surgery, and the symptoms were relieved after 7 days of treatment with hormones, dehydration drugs and symptomatic management.@*CONCLUSION@#Unilateral biportal endoscopy technique has a good early clinical efficacy in the treatment of lumbar postoperative adjacent segmental diseases, which may provide a new minimally invasive, non-fixation option for the treatment of adjacent segment disease.

ABSTRACT We describe two cases of surgical treatment of craniovertebral stenosis in preschool-aged brothers with Maroteaux-Lamy (MPS type VI) syndrome. The older brother was diagnosed with MPS during her second pregnancy. Literature describing familial cases of the disease and the treatment strategy in young children with MPS type VI and spinal canal stenosis is scarce. Based on the presented observations, indications, surgical treatment approaches, and perioperative management of patients with mucopolysac-charidosis are suggested. MPS type VI may have familial forms of the disease and the course of craniovertebral stenosis is similar in siblings. Surgical treatment of craniovertebral stenosis in these patients should be performed timely. We adhere to the point of view of early treatment of craniovertebral stenosis in patients with MPS before irreversible spinal cord dysfunction develops.

Resumo: Descreve-se dois casos de tratamento cirúrgico de estenose craniovertebral entre irmãos em idade pré-escolar com síndrome de Maroteaux-Lamy (MPS tipo VI). O irmão mais velho foi diagnosticado com MPS durante a segunda gravidez. A literatura que descreve casos familiares da doença e a estratégia de tratamento em crianças pequenas com MPS tipo VI e estenose do canal raquidiano é escassa. Com base nas observações apresentadas, foram sugeridas indicações, abordagens de tratamento cirúrgico e manejo perioperatório de pacientes com mucopolissacaridose. A MPS tipo VI pode apresentar formas familiares da doença e o curso da estenose craniovertebral é semelhante entre irmãos. O tratamento cirúrgico da estenose craniovertebral nesses pacientes deve ser realizado em tempo hábil. Adere-se ao conceito de tratamento precoce da estenose craniovertebral em pacientes com MPS antes que se desenvolva uma disfunção irreversível da medula espinhal.

INTRODUÇÃO: A claudicação neurogênica (CN) é a apresentação clínica clássica de pacientes com Estenose Espinhal Lombar (EEL). Esses pacientes podem ou não apresentar sintomas de dor nas pernas e dificuldade para caminhar. Esses sintomas são exacerbados ao caminhar e ficar em pé e são aliviados ao sentar ou inclinar-se para a frente. MÉTODO: Pacientes com EEL, com diâmetro do canal lombar ≤12mm, foram recrutados em um hospital terciário reconhecido. As características demográficas e antropométricas de cada sujeito foram anotadas e o procedimento do teste foi explicado. O diâmetro do canal foi documentado com a ajuda de um relatório de ressonância magnética. Um teste de caminhada individualizado foi usado para avaliar a distância percorrida. ANÁLISE ESTATÍSTICA: Dependendo da normalidade dos dados, o coeficiente de correlação de Pearson (r) foi usado para encontrar a correlação entre o diâmetro do canal em diferentes níveis lombares e a distância percorrida em pacientes com EEL. RESULTADO: O coeficiente de correlação de Pearson (r) determinou uma correlação positiva razoável (r = 0,29) entre o diâmetro do canal lombar e a distância percorrida. Análise de regressão múltipla stepwise foi feita, e uma equação de predição foi encontrada para diferentes níveis de estenose do canal. CONCLUSÃO: Os achados de nosso estudo sugerem uma correlação positiva razoável entre a distância percorrida e o diâmetro do canal em L5-S1. Este estudo também pode ser útil para prever o diâmetro aproximado do canal, estimando a distância percorrida pelo paciente com sintomas de EEL e vice-versa.
INTRODUCTION: Neurogenic claudication (NC) is the classic clinical presentation of patients with Lumbar Spinal Stenosis (LSS). These patients may or may not present with symptoms of leg pain and difficulty walking. These symptoms are exacerbated while walking and standing and are eased by sitting or bending forward. METHOD: Patients with LSS, having a lumbar canal diameter of ≤12mm, were recruited from a recognized Tertiary care hospital. Each subject's demographic characteristics and anthropometrics were noted, and the testing procedure was explained. The canal diameter was documented with the help of an MRI report. A self-paced walking test was used to assess the walking distance. STATISTICAL ANALYSIS: Depending on the normality of the data, the Pearson correlation coefficient (r) was used to find the correlation between canal diameter at different lumbar levels and walking distance in patients with LSS. RESULT: Pearson correlation coefficient (r) determined a fair positive correlation (r = 0.29) between lumbar canal diameter and walking distance. Stepwise multiple regression analysis was done, and a prediction equation was found for different levels of canal stenosis. CONCLUSION: Findings of our present study suggest a fair positive correlation between walking distance and canal diameter at L5-S1. This study may also be useful in predicting the approximate canal diameter by estimating the walking distance of the patient with symptoms of LSS and vice-versa.

Percutaneous endoscopic spine decompression(PSED) in recent years in the treatment of degenerative lumbar spinal stenosis(DLSS) achieved excellent results.Compared with traditional open surgery, which is characterized by large trauma, much bleeding, longer bed stay and slow recovery, the rapid development of PSED technology has greatly reduced the surgical trauma, postoperative recovery time and complications of DLSS patients. PSED core as the target therapy, with minimal trauma at the same time to achieve satisfactory decompression effect for lumbar spinal stenosis. Depending on the level, location, and degree of lumbar spinal stenosis, it is important to determine the ideal treatment. However, in practice, PSED has insufficient understanding of the treatment of different pathological types of lumbar spinal stenosis, such as indication selection, surgical approach selection, advantages and limitations of various approaches, and endoscopic vertebral fusion.At present, with the deepening of PSED research and the improvement of endoscopic instruments, great progress has been made in the treatment of DLSS.In this paper, the research progress in the treatment of DLSS by PSED in recent years will be described from four aspects, namely, the grasp of indications, the selection of approaches, the advantages and disadvantages of endoscopic approaches, and endoscope-assisted vertebral fusion, in order to provide certain guidance for the clinical treatment of DLSS by PSED.

OBJECTIVE@#To manufacture a new type of transverse process retractor by using computer-aided design(CAD) combined with 3D printing technology and investigate its clinical application effect.@*METHODS@#A new type of transverse protrusion retractor was developed by CAD combined with 3D printing technology. From September 2018 to September 2019, the new transverse process retractor was applied in clinic. Sixty patients with lumbar single segment lesions who needed treatment by pedicle screw fixation, bone grafting and interbody fusion were divided into new transverse process retractor group and control group, with 30 cases in each group. There were 14 males and 16 females in new type transverse process retractor group, the age was (68.0±4.3) years old on average; lesion segment of 8 cases were L3,4, 9 cases were L4,5, 13 cases were L5S1;5 cases of lumbar disc herniation, 20 cases of lumbar spinal stenosis, 5 cases of degenerative lumbar spondylolisthesis;new transverse process retractor was used to pedicle screw placement. While there were 15 males and 15 females in control group, with an average age of (69.2±4.5) years old;lesion segment of 8 cases were L3,4, 10 cases were L4,5, 12 cases were L5S1;5 cases of lumbar disc herniation, 21 cases of lumbar spinal stenosis, 4 cases of degenerative lumbar spondylolisthesis;the traditional lamina retractor was used for soft tissue pulling and finished pedicle screw placement by freehand. The length of surgical incision, the time required for inserting a single screw, fluoroscopy times, the times of adjusting the positioning needle or screw in insertion process, and the visual analogue scale (VAS) of surgical incision 72 hours after operation were compared between two groups.@*RESULTS@#Using CAD and 3D printing technology, a new type of transverse protrusion retractor was developed quickly. The length of surgical incision, the time required for inserting a single screw, fluoroscopy time, and the times of adjusting the positioning needle or screw in insertion process in new transverse process retractor group were less than those in control group(P<0.05). There was no significant difference in VAS of lumbar incision pain at 72 hours after operation between two groups(P>0.05).@*CONCLUSION@#Using CAD combined with 3D printing technology to develop a new transverse protrusion retractor has the advantages of convenient design, short development cycle and low cost. It provides a new idea for the research and development of new medical devices. The new transverse process retractor has the advantages of easy operation, reliable fixation, less damage to paravertebral muscle, convenient pedicle screw placement, reducing fluoroscopy time and so on.

ABSTRACT Objective This study was conducted to determine the frequency of vitamin D deficiency in patients with lumbar spinal stenosis and to define the relationship between vitamin D levels and obesity, depression, and pain intensity. Methods This study was conducted with 69 patients (Male = 32, Female = 37) diagnosed with lumbar spinal stenosis. The participants' 25(OH)D levels were measured by radioimmunoassay. In addition, bone metabolic status, including bone mineral density and bone turnover markers, was also evaluated. The Beck Depression Inventory was used to determine the depression statuses of the patients, while the McGill Melzack Pain Questionnaire was administered to measure pain intensity. The results were evaluated at a significance level of p<0.05. Results Vitamin D deficiency (<20 ng/mL) was found in 76.8% of the patients. Binary logistic regression analysis showed a significantly higher frequency of vitamin D deficiency in patients who: 1) had higher body mass indexes (OR 3.197, 95% CI 1.549-6.599); 2) fared higher in Beck's depression score (OR 1.817, 95% CI 1.027-3.217); and 3) were female rather than male (OR 1.700, 95% CI 0.931-3.224) (p<0.05). Conclusion In this study, vitamin D deficiency was prevalent in lumbar spinal stenosis patients. In addition, obese, depressed, and female individuals have higher risks of vitamin D deficiency.
RESUMO Objetivo Este estudo foi realizado para determinar a frequência de deficiência de vitamina D em pacientes com estenose espinhal lombar e para definir a relação entre os níveis de vitamina D e obesidade, depressão e intensidade da dor. Métodos Este estudo foi realizado com 69 pacientes (homens = 32, mulheres = 37) diagnosticados com estenose espinhal lombar. Os níveis de 25(OH)D dos participantes foram medidos por radioimunoensaio. Além disso, o estado metabólico ósseo, incluindo densidade mineral óssea e marcadores de remodelação óssea, também foi avaliado. O Inventário de Depressão de Beck foi usado para determinar os estados de depressão dos pacientes, enquanto o Questionário de Dor McGill Melzack foi aplicado para medir a intensidade da dor. Os resultados foram avaliados a um nível de significância de p<0,05. Resultados A deficiência de vitamina D (<20 ng/mL) foi encontrada em 76,8% dos pacientes. A análise de regressão logística binária mostrou uma frequência significativamente maior de deficiência de vitamina D nos seguintes pacientes: 1) com maior índice de massa corporal (OR 3,197, 95% IC 1,549-6,599); 2) com maior pontuação na escala de depressão de Beck (OR 1,817, 95% IC 1,027-3,217) e 3) do sexo feminino em vez de masculino (OR 1,700, 95% IC 0,931-3,224) (p<0,05). Conclusão Neste estudo, a deficiência de vitamina D foi prevalente em pacientes com estenose espinhal lombar. Além disso, pessoas obesas, deprimidas e mulheres correm maior risco de deficiência de vitamina D.

ABSTRACT Objective: To evaluate degenerative lumbar stenosis in symptomatic patients submitted to surgeryand the correlation between probable determining factors. Methods: A retrospective descriptive study in which themagnetic resonance images of 73 patients with degenerative stenosis,who underwent surgeries involving 141 levels performed by a single surgeon at the Hospital Ortopédico de Passo Fundo from 2015 to 2018, were evaluated. The patients were stratified by the degree of facet tropism, facet arthrosis, disc degeneration, and operated side, as well as by epidemiological data such as age, sex, etc. Tropism was measured using the Karacan method and evaluated numerically and categorically. Disc degeneration was classified by Pfirrmann and facet arthrosis by Weishaupt. To analyze and obtain the results, the Chi-square test and ANOVA were used with the SPSS statistical program, version 18.0. Results: Statistical significance was found in the relationship between facet tropism and disc degeneration (p=0.026) at the L4-L5 level. No correlation was found between tropism and facet arthrosis (p=0.161) or tropism and the operated side (p=0.573). Conclusion: The degree of tropism directly influences disc degeneration and greater asymmetries are related to more severe degenerations. Although tropism has not shown a statistically significant correlation with the operated side (p=0.573), it is believed that further studies should be carried out on this correlation. Level of evidence II; Retrospective study.
RESUMO Objetivo: Avaliar a estenose lombar degenerativa em pacientes sintomáticos submetidos à cirurgia, analisando a correlação entre fatores determinantes prováveis. Métodos: Estudo retrospectivo descritivo, no qual foram avaliados exames de ressonância nuclear magnética de 73 pacientes, totalizando 141 níveis com estenose degenerativa submetidos a tratamento cirúrgico por um único cirurgião do Hospital Ortopédico de Passo Fundo, de 2015 até 2018. Os pacientes foram estratificados de acordo com grau do tropismo facetário, artrose facetária, degeneração discal e lado operado, assim como com dados epidemiológicos como idade, sexo, etc. O tropismo foi aferido pelo método de Karacan e avaliado de forma numérica e categórica. A degeneração discal foi classificada por Pfirrmann e a artrose facetária por Weishaupt. Para análise e obtenção dos resultados foi utilizado o teste do qui-quadrado e ANOVA com oprograma estatístico SPSS versão 18.0. Resultados: Verificou-se significância estatística na relação entre tropismo facetário e degeneração discal (p=0,026) no nível L4-L5. Não foi encontrada correlação entre tropismo e artrose facetária (p=0,161) ou tropismo e lado operado(p=0,573). Conclusões: O grau de tropismo influencia diretamente a degeneração discal, sendo que as assimetrias maiores estão relacionadas a degenerações mais graves. Embora o tropismo não tenha demonstrado correlação estatística significativa com o lado operado (p=0,573), acredita-se que deverão ser realizados novos estudos sobre essa correlação. Nível de evidência II; Estudo retrospectivo.

El dolor lumbar bajo y el dolor cervical con o sin irradiación son causas muy comunes de consulta a los médicos generalistas en los países desarrollados. La discopatía aguda y el dolor por estenosis del canal espinal son los diagnósticos más frecuentes. La postura tradicional ha sido la de administrar antiinflamatorios no esteroideos (AINES) para estas lumbalgias o cervicalgias agudas. Cuando existe irradiación neural por compresión radicular es usual asociar al AINE un corticoide a baja dosis, así como un antineurítico, para lograr un mejor resultado. Con el objeto de documentar la utilidad de esta práctica habitual, efectuamos en 142 pacientes ambulatorios un estudio multicéntrico randomizado que compara la efectividad y la tolerancia de una asociación a dosis fija de diclofenac, betametasona y cianocobalamina administrada por vía oral versus la administración de diclofenac como monofármaco en el tratamiento de la patología dolorosa de la columna lumbar y cervical asociada a compresión neural. La asociación demostró ser más eficaz en controlar el dolor y mejorar la funcionalidad de los pacientes que la administración de diclofenac en forma aislada y se asoció a escasos efectos colaterales, principalmente digestivos
Low back pain and neck pain with or without radiation are very common causes of consultation with general practitioners in developed countries. Acute discopathy and pain due to spinal canal stenosis are the most frequent diagnoses. The traditional approach has been to administer non-steroidal antiinflammatory drugs (NSAIDs) for these acute low back or cervical pain. When there is neural radiation due to root compression, it is usual to associate a low-dose corticosteroid with the NSAID, as well as an antineuritic, to achieve a better result. In order to document the usefulness of this routine practice, we conducted a randomized multicenter study in 142 outpatients that compared the effectiveness and tolerance of a fixed-dose combination of diclofenac, betamethasone, and cyanocobalamin administered orally versus the administration of diclofenac as Monopharmaceutical in the treatment of painful pathology of the lumbar and cervical spine associated with neural compression. The association proved to be more effective in controlling pain and improving the functionality of patients than the administration of diclofenac in isolation and was associated with few side effects, mainly digestive
