RESUMO

OBJECTIVE: To observe the clinical effect of transforaminal endoscopy combined with interspinous fusion in the treatment of lumbar spinal stenosis with instability in the elderly. METHODS: From February 2018 to February 2019, 82 elderly patients with lumbar spinal stenosis and instability were divided into control group and observation group. In the control group, there were 23 males and 18 females;the age was (68.9±4.1) years;the course of disease was (14.1±5.7) months;there were 5 cases of single segment lesions and 36 cases of multi segment lesions;simple bacfuse interspinous fusion was used. In the observation group, there were 22 males and 19 females;the age was (69.1±4.0) years;the course of diseasewas (14.4±5.5) months;there were 6 cases of single segment lesions and 35 cases of multi segment lesions;they were treated with transforaminal endoscopic surgery combined with Bacfuse interspinous fusion. The clinical efficacy, visual analogue scale (VAS), Japanese Orthopaedic Association scores (JOA), Oswestry disability index (ODI), Lehmann lumbar function score, posterior disc height and intervertebral foramen height, complication rate and recurrence rate of the two groups were compared. RESULTS: The clinical efficacy of the observation group was better than that of the control group;the VAS score of the observation group was lower than that of the control group, the JOA score was higher than that of the control group, and the ODI index at 3 months after operation and at the last follow-up was lower than that of the control group, the Lehmann lumbar function score was higher than that of the control group;the posterior edge height of intervertebral disc and intervertebral foramen height were higher than those of the controlgroup;the incidence of complications and recurrence rate (4.9% and 0.0%) of the observation group were lower than those of the control group (19.5%, 9.8%), the difference was statistically significant (P<0.05). CONCLUSION: The clinical effect of transforaminal endoscopy combined with interspinous process fusion in the treatment of lumbar spinal stenosis with instability in the elderly is ideal. It can reduce postoperative pain, improve lumbar function, improve the height of posterior edge of intervertebral disc and intervertebral foramen, and reduce the incidence and recurrence rate. It is worthy of clinical promotion.

RESUMO

RATIONALE: Intraoperative neurophysiological monitoring (IONM) is widely used in spinal surgeries to prevent iatrogenic spinal cord injury (SCI). Most surgeons focus on avoiding neurological compromise intraoperatively, while ignoring the possibility of nerve damage preoperatively, such as neck positioning. Thus, this study aims to report a case with transient neurological deterioration due to improper neck position detected by IONM during cervical surgery. PATIENT CONCERNS: A 63-year-old male patient had been suffering from hypoesthesia of the upper and lower extremities for three years. DIAGNOSES: Severe cervical stenosis (C5-C7) and cervical ossification of a posterior longitudinal ligament. INTERVENTIONS: The cervical stenosis patient underwent an anterior cervical corpectomy decompression and fusion (ACDF) surgery with the assistance of IONM. When the lesion segment was exposed, the SSEP and MEP suddenly elicited difficulty indicating that the patient may have developed SCI. All the technical causes of IONM events were eliminated, and the surgeon suspended operation immediately and suspected that the IONM alerts were caused by cervical SCI due to the improper position of the neck. Subsequently, the surgeon repositioned the neck of the patient by using a thinner shoulders pad. OUTCOMES: At the end of the operation, the MEP and SSEP signals gradually returned to 75% and 80% of the baseline, respectively. Postoperatively, the muscle strength of bilateral biceps decreased from grade IV to grade III. Besides, the sensory disturbance of both upper extremities aggravated. However, the muscle power and hypoesthesia were significantly improved after three months of neurotrophic therapy and rehabilitation training, and no complications of nerve injury were found at the last follow-up visit. LESSONS: IONM, consisting of SSEP and MEP, should be applied throughout ACDF surgery from the neck positioning to suture incisions. Besides, in the ward 1to 2 days before operation, it is necessary for conscious patients with severe cervical stenosis to simulate the intraoperative neck position. If the conscious patients present signs of nerve damage, they can adjust the neck position immediately until the neurological symptoms relieve. Therefore, intraoperatively, the unconscious patient can be placed in a neck position that was confirmed preoperatively to prevent SCI.

RESUMO

OBJECTIVE: To evaluate clinical effect of unilateral approach and bilateral decompression via large channel endoscopic system for the treatment of lumbar spinal stenosis. METHODS: The clinical data of 32 patients with lumbar spinal tenosis treated by unilateral approach and bilateral decompression via large channel endoscopy from February 2018 to February 2019 were retrospectively analyzed. There were 18 males and 14 females, aged 65 to 84 years old with an average of (70.6± 8.4) years. The course of disease was from 1 to 12 years. All 32 cases were accompanied by numbness or pain in the lower limbs, of which 28 cases were accompanied by intermittent claudication. Narrow segments were L3, 4 of 2 cases, L4, 5 of 19 cases, L5S1 of 13 cases, including double segments of 2 cases. Preoperative imaging showed 3 cases of central canal stenosis, 21 cases of bilateral lateral recess stenosis and 8 cases of mixed stenosis. Operation time and complications were recorded. X-ray, CT and MRI were analyzed at 3 days, 3 months and 1 year after operation. Visual analogue scale(VAS), Oswestry Disability Index (ODI), single continuous walking distance(SCWD) were observed before and after operation. Modified Macnab standard were used to evaluate the clinical effect at 1 year after operation. RESULTS: All the patients were followed up for 12-24 (17.68±2.43) months and all operations were successfully completed with the operation time of 70-160(85.64±11.94) min. Spinal dural tear occurred in 1 case during the operation, and sensory disturbance in the other side of lower limb in a short period of time occurred in 2 cases, all improved after corresponding treatment. Postoperative imaging showed that the spinal canal was significantly enlarged and the nerve root was fully released. Before operation and 3 days, 3 months, 1 year after operation, VAS scores of low back pain were 4.62 ±1.41, 2.73 ±1.35, 1.21 ±1.17, 1.11 ±0.34, respectively;VAS scores of leg pain were 6.83 ± 1.71, 3.10±1.50, 1.08±0.19, 0.89±0.24, respectively. VAS scores of low back pain and leg pain each time point after operation were obvious improved (P<0.05); there was significant difference between 3 months and 3 days after operation(P<0.05), and there was no significant difference between 3 months and 1 year after operation (P>0.05). Before operation and 3 days, 3 months, 1 year after operation, ODI scores were 38.40 ±6.48, 18.42 ±2.40, 5.48 ±0.77, 3.05 ±0.28, respectively; SCWD was (47.48±5.32) m, (52.89±11.23) m, (245.43±18.94) m, (468.97±55.87) m, respectively. The differences in ODI score and SCWD postoperative time points were statistically significant compared with those before operation (P<0.05). The difference between 3 months and 3 days after operation was statistically significant (P<0.05). The difference between 1 year and 3 months after operation was statistically significant (P<0.05). According to Macnab standard to evaluate clinical effect at 1 year after operation, 15 cases got excellent results, 14 good, 3 fair. CONCLUSION: It is a safe and effective way to treat lumbar spinal stenosis with unilateral approach and bilateral decompression via large channel endoscopic system. It has the advantages of sufficient decompression, less trauma, fast recovery, high safety and low incidence of postoperative complications. It can minimize the damage to the stable structure of the lumbar spine and is an ideal minimally invasive operation for the treatment of lumbar spinal stenosis.

RESUMO

ABSTRACT: Biportal endoscopic spine surgery (BESS) is extending its application to most kind of spine surgeries. Postoperative spinal epidural hematoma (POSEH) is one of the major concerns of this emerging technique. Through this study we aim to investigate the incidence of POSEH in BESS comparing to a conventional spine surgery (CSS).The patients who underwent a non-fusion decompressive spine surgery due to degenerative lumbar spinal stenosis (LSS) or herniated lumbar disc (HLD) or both between January 2015 and March 2019 were reviewed retrospectively. The incidence of clinical POSEH that demanded a revision surgery for hematoma evacuation was compared between CSS and BESS. As a second endpoint, the morphometric degree of POSEH was compared between the two groups. The maximal compression of cauda equina by POSEH was measured by 4 grade scale at the T2 axial image and the neurological state was evaluated by 5 grade scale. The indication of hematoma evacuation was more than hG3 with more than nG1. As a subgroup analysis, risk factors of POSEH in BESS were investigated.The 2 groups were homogenous in age, sex, number and level of operated segments. There was significant difference in the incidence of symptomatic POSEH as 2/142 (1.4%) in CSS and 8/95 (8.4%) in BESS (P = .016). The radiological thecal sac compression by hematoma was hG1 65 (61.3%), hG2 35 (33.0%), hG3 5 (4.7%), hG4 1 (0.9%) cases in CSS and hG1 33 (39.8%), hG2 25 (30.1%), hG3 22 (26.5%), hG4 3 cases (3.6%) in BESS. The difference was significant (P < .001). In BESS subgroup analysis, the risk factor of high grade POSEH was bilateral laminectomy (OR = 8.893, P = .023).The incidence of clinical and morphometric POSEH was higher in BESS. In BESS, POSEH developed more frequently in bilateral laminectomy than unilateral laminectomy.

RESUMO

Objective: To observe the difference between crenel lateral interbody fusion (CLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of degenerative lumbar spondylolisthesis (DLS) combined with lumbar spinal stenosis (LSS). Methods: The clinical data of DLS combined with LSS patients meeting the selection criteria admitted between May 2018 and May 2019 were retrospectively analyzed. According to different surgical methods, the patients were divided into CLIF group (33 cases) and TLIF group (32 cases). There were no significant differences ( P>0.05) between the two groups in gender, age, disease duration, lesion segments, lumbar bone mineral density, degree of lumbar spondylolisthesis, and preoperative visual analogue scale (VAS) score, Oswestry disability index (ODI), intervertebral space height, intervertebral foramen height, lumbar lordosis (LL), and segmental lordosis (SL). The operation time, intraoperative blood loss, and perioperative complications were recorded and compared between the two groups. Lumbar CT scan was performed at last follow-up to compare the intervertebral fusion rate between the two groups. Intervertebral space height, intervertebral foramen height, LL, and SL were measured before operation, at 2 weeks, 3 months after operation, and at last follow-up. VAS score and ODI were used to evaluate the pain and improvement of the quality of life of the patients. Results: There were no neurological and vascular complications in the two groups. The operation time and intraoperative blood loss in CLIF group were significantly less than those in TLIF group ( P<0.05). Patients in both groups were followed up for a median time of 18 months. All the incisions healed by first intention except 1 incision in TLIF group because of poor blood glucose control. No complications such as bedsore, falling pneumonia, and deep venous thrombosis were found in both groups. At last follow-up, the intervertebral fusion rates in CLIF and TLIF group were 90.91% (30/33) and 93.75% (30/32), respectively, showing no significant difference ( χ 2=0.185, P=0.667). The VAS score, ODI, intervertebral space height, intervertebral foramen height, LL, and SL were significantly improved in both groups at each time point after operation ( P<0.05). Except that VAS score in CLIF group was significantly lower than that in TLIF group at 2 weeks after operation ( Z=-4.303, P=0.000), there were no significant differences in VAS score and ODI between the two groups at other time points ( P>0.05). The intervertebral space height, intervertebral foramen height, LL, and SL in CLIF group were significantly higher than those in TLIF group at each time point after operation, and the differences were significant ( P<0.05). Conclusion: CLIF in the treatment of DLS combined with LSS can achieve the similar effectiveness with traditional TLIF, and has such advantages as minimal invasion and faster recovery.

RESUMO

BACKGROUND: Wild-type transthyretin (ATTRwt) amyloid deposits have been found in the ligamentum flavum of patients undergoing surgery for spinal stenosis. The relationship between ATTRwt and ligamentum flavum thickness is unclear. We used pre-operative magnetic resonance imaging (MRI) to analyze ligamentum flavum thickness in lumbar spinal stenosis patients with and without ATTRwt amyloid. METHODS: We retrospectively identified 178 patients who underwent lumbar spine surgery. Ligamentum flavum thickness of 253 specimens was measured on T2-weighted axial MRI. Amyloid presence was confirmed through Congo red staining of specimens, and ATTRwt was confirmed using mass-spectrometry and gene sequencing. RESULTS: Twenty four of the 178 patients (13.5%) were found to have ATTRwt in the ligamentum flavum. Forty ATTRwt specimens and 213 non-ATTRwt specimens were measured. Mean ligamentum flavum thickness was 4.92 (±1.27) mm in the ATTRwt group and 4.00 (±1.21) mm in the non-ATTRwt group (p < 0.01). The ligamentum flavum was thickest at L4-L5, with a thickness of 5.15 (±1.27) mm and 4.23 (±1.29) mm in the ATTRwt and non-ATTRwt group, respectively (p = 0.007). There was a significant difference in ligamentum flavum thickness between ATTRwt and non-ATTRwt case for both patients younger than 70 years (p = 0.016) and those older than 70 years (p = 0.004). ATTRwt patients had greater ligamentum flavum thickness by 0.83 mm (95% confidence interval (CI): 0.41-1.25 mm, p < 0.001) when controlled for age and lumbar level. CONCLUSION: Patients with ATTRwt had thicker ligamentum flavum compared to patients without ATTRwt. Further studies are needed to investigate the pathophysiology of ATTRwt in ligamentum flavum thickening.

RESUMO

PURPOSE: To describe a modified minimally invasive spine (MIS) procedure to treat lumbar developmental spinal stenosis (DSS) to achieve complete decompression and fusion. The method preserves the muscles, ligaments, and most of the bony structures. DSS is not considered a good indication for MIS procedures and few reports discuss alternative treatments. Because MIS has the advantages of low blood loss, rapid recovery, and short hospital stay, it would be ideal for DSS. METHODS: After confirming the screw positions, we placed a tube retractor in the facet joint on the decompressed side. The inferior facet joint and part of the superior joint of the lower segment were removed, the spinal canal was carefully exposed under a microscopic view, and fusion was performed through Kambin's triangle. Next, the operation table was rotated to the contralateral side and angled to approximately 15-20 degrees. We then tilted the tube retractor in the facet joint toward the operation side by 15-20 degrees, which provided access to the contralateral canal for decompression. The ligament flavum was carefully removed and the dural sac was gently retracted to expose the lateral recess on the other side. We then examined the nerve root on the contralateral side to ensure there was no compression. RESULTS: Eight patients with lumbar DSS were treated using this method. Patients' neurological symptoms improved greatly without complications and patients were able to walk the day after surgery. The inner plate of the contralateral lamina and muscle as well as most of the ligaments that contribute to stability were preserved. CONCLUSION: This modified MIS decompression procedure successfully treated DSS by providing spinal canal decompression and preserving most of the stabilizing structures.

RESUMO

Recently, various designs and material manufactured interspinous process devices (IPDs) are on the market in managing symptomatic lumbar spinal stenosis (LSS). However, atraumatic fracture of the intervening spinous process has been reported in patients, particularly, double or multiple level lumbar decompression surgery with IPDs. This study aimed to biomechanically investigate the effects of few commercial IPDs, namely DIAMTM, CoflexTM, and M-PEEK, which were implanted into the L2-3, L3-4 double-level lumbar spinal processes. A validated finite element model of musculoskeletal intact lumbar spinal column was modified to accommodate the numerical analysis of different implants. The range of motion (ROM) between each vertebra, stiffness of the implanted level, intra stress on the intervertebral discs and facet joints, and the contact forces on spinous processes were compared. Among the three implants, the Coflex system showed the largest ROM restriction in extension and caused the highest stress over the disc annulus at the adjacent levels, as well as the sandwich phenomenon on the spinous process at the instrumented levels. Further, the DIAM device provided a superior loading-sharing between the two bridge supports, and the M-PEEK system offered a superior load-sharing from the superior spinous process to the lower pedicle screw. The limited motion at the instrumented segments were compensated by the upper and lower adjacent functional units, however, this increasing ROM and stress would accelerate the degeneration of un-instrumented segments.

RESUMO

BACKGROUND: Most degenerative lumbar spinal stenosis (DLSS) patients primitively received the conservative treatment to control symptoms. In order to develop an optimal surgical treatment strategy, it is very significant to understand how the degenerative lumbar spondylolisthesis (DS) affects the effect of decompression in the DLSS. Thus, the aim of this current study was to explore whether the concomitant DS would affect the effect of decompression alone in the patients with DLSS. METHODS: The current study was carried out at our hospital and it was approved through our institutional review committee of General Hospital of Ningxia Medical University. During the period from January 2015 to December 2017, in our study, we identified consecutive patients who received the minimally invasive laminectomy to treat the DLSS. The inclusion criterion included radicular leg pain or neurogenic claudication with the neurological symptoms associated with DLSS syndrome, magnetic resonance imaging of the lumbar spine reveals at least 1 level of serious stenosis, the conservative treatment failed for at least 3 months, and patients agreed to provide the postoperative details. The major outcomes of this present research was Oswestry Disability Index. Secondary outcomes of this current study involved visual analog score, short form-36, surgical revision rate as well as complications. RESULTS: We assumed that previous DS possessed a negative effect on the postoperative results of the DLSS patients. TRIAL REGISTRATION: researchregistry5943.

RESUMO

BACKGROUND: Many complications are associated with thoracic open decompression surgery, such as dural tears and neurological deficits. The clinical outcomes are also not satisfactory. Full-endoscopic decompression of the lumbar spinal canal has achieved satisfactory results for the treatment of lumbar spinal stenosis. This surgery may be used for the treatment of thoracic ossification of the ligamentum flavum (OLF) under local anesthesia. The aim of our study is to introduce the surgical techniques used for full-endoscopic decompression for thoracic OLF and to evaluate its safety and efficacy. METHODS: Fourteen patients with thoracic OLF (4 combined with dural ossification) underwent full-endoscopic decompression surgery. An interlaminar approach was performed. The anchoring method was used to establish the working passage. Spinal cord exposure began at a space between the ossification and the spinal cord, and dorsal and contralateral decompression were performed with the "Over the Top" technique. The modified Japanese Orthopedic Association score (11 points) was used to evaluate the efficacy during follow-up. At the same time, the visual analogue scale score for assessing back pain before and after the operation was evaluated. RESULTS: The average operation time was 159.73 ±â€Š62.09 minutes, and the hospitalization time was 7.43 ±â€Š1.79 days. The follow-up period ranged from 8 to 22 months. Neurological function was improved. There were no serious complications. Dural tears occurred in 5 patients, intraoperative neurological deterioration occurred in 1 patient, and intraoperative headache and neck pain occurred in 1 patient. CONCLUSION: Full-endoscopic decompression is an effective, safe surgical technique for thoracic OLF even the cases combined with dural ossification.

RESUMO

OBJECTIVE: The goal of this study was to review relevant studies in order to determine the efficacy of decompression with fusion versus decompression in the treatment of lumbar spinal stenosis. METHODS: Using appropriate keywords, we identified relevant studies using PubMed, the Cochrane library, and Embase. Key pertinent sources in the literature were also reviewed, and all articles published through October 2019 were considered for inclusion. For each study, we used odds ratios, mean difference (MD), and 95% confidence interval (95% CI) to assess and synthesize outcomes. RESULTS: We found 13 studies that were consistent with this meta-analysis with a total of 29066 patients. Compared with decompression, decompression with fusion significantly increased the incidence of complications (RR: 1.41, 95%CI: 1.26-1.57), the length of hospital stay (WMD: 1.868, 95%CI: 1.394-2.343), operative time (WMD: 80.399, 95%CI: 44.397-116.401), estimated blood loss (WMD: 309.356, 95%CI: 98.008-520.704) and Zurich claudication questionnaire in symptom severity (WMD: 0.200, 95%CI: 0.006-0.394). The reoperation rate was lower in the decompression with fusion group than the decompression group but without significant difference (RR: 0.91, 95%CI: 0.82-1.00). There was no significant difference between 2 groups in visual analog scale (leg pain and back pain), ODI, Short Form 36 Health Survey physical component summary, Short Form 36 Health Survey mental component summary, and Zurich claudication questionnaire physical function. CONCLUSION: Decompression with fusion has no significant clinical advantages in treatment of lumbar spinal stenosis when compared with decompression.

RESUMO

The clinical outcomes of redundant nerve root syndrome (RNRS) in patients with lumbar foraminal spinal stenosis (LFSS) are currently unknown. The purpose of this study was to evaluate the postprocedural outcomes of RNRS in LFSS after percutaneous lumbar foraminoplasty (PLF) and identify the factors associated with RNRS by comparative analysis between patients with and without RNRS.Patients with LFSS who underwent PLF were retrospectively analyzed. RNRS is defined as the presence of thick, elongated, and tortuous structures in the cauda equine associated with lumbar spinal stenosis. Based on the sagittal or transverse magnetic resonance imaging scans obtained before the PLF, the patients were stratified into 2 groups. Comparative analysis was performed between patients with RNRS (group R) and those without RNRS (group C).From March 2016 to January 2019, 8 of the 21 (38.1%) patients undergoing PLF showed signs of RNRS on magnetic resonance imaging images. PLF showed a tendency for less therapeutic effect with respect to changes in pain intensity in group R as compared to group C, but there were no statistically significant differences between the 2 groups. RNRS correlated with the cross-sectional area (CSA) of the dural sac and LFSS grade (P < .05). The CSA of the dural sac was smaller and the grade of LFSS was higher in group R than in group C.RNRS is commonly associated with lumbar spinal stenosis and could affect the treatment outcomes. Clinical outcomes in group R were not statistically different from those in group C, although group R showed slightly worse outcomes. The independent factors associated with RNRS were CSA of the dural sac and the LFSS grade.

RESUMO

The aim of the study was to analyze the results of treatment with biportal endoscopic decompression of patients with spinal stenosis. The treatment results of 62 patients who underwent surgery (for discectomy) (for decompression) in the period from March 2018 to June 2019 were analyzed. All 62 patients were operated by biportal endoscopy at the spine surgery clinic of the State Institution "Institute of Traumatology and Orthopedics of the National Academy of Medical Sciences of Ukraine". Pain intensity was assessed using a visual analogue pain scale (VAS), patient satisfaction and quality of life was assessed using a modified MacNab scale and the Oswestry Disability Index (ODI), respectively, 1 week, 3 months and 6 months after surgery. Perioperative data were also evaluated (duration of surgery and length of stay in the hospital, blood loss and complications). X-ray results were evaluated using pre- and postoperative MRI (6-8 weeks after surgery). According to the results of studies in the postoperative period, a positive trend was observed. So, the indicator of back pain according to VAS after surgery decreased to 0,9±1,4 points, and the indicator of pain in the leg according to VAS on average in the postoperative phase was 1,28±1,1 points, respectively. Assessing perioperative data, in the group of patients the level of blood loss was 34,8±16,2, and the length of stay in the hospital was 2,9±1,3 days. Among the complications, 4 cases of point wound of the dural membrane and 1 case of linear wound of the dural membrane, more than 1 cm long with the contents of the dural sac entering the epidural space, which required conversion to an open operation with suturing the defect, were noted. Biportal endoscopic spinal surgery is an effective method of treating lumbar spinal stenosis, which has several advantages over open surgery (less tissue trauma, less blood loss, high patient satisfaction with the treatment result). UBE has an advantage over microscopic technique in terms of achieving complete decompression in an enlarged arthroscopic field without restricting the movement of the instrument due to the use of an independent portal, and continuous irrigation with saline during surgery is a great advantage to prevent infection.

RESUMO

Objective: To compare clinical outcomes of microsurgical bilateral decompression via unilateral approach (MBDU) between trans longissimus and iliocostalis approach, a novel lateral paraspinal approach(LPA), and classic Wiltseapproach for single level degenerative lumbar stenosis. Methods: LPA approach was researched by imaging measurement and cadaver anatomy. Retrospective analysis of a total 124 cases(male/female 75/49, aged(55±14) years) received single-level MBDU due to degenerative lumbar stenosis from 2016 to 2018 in Beijing Tiantan Hospital. Patients were categorized into two groups according to spinal canal morphology. Group A: trefoil shape (n=48), received MBDU via LPA; Group B: round & oval shape (n=76), received MBDU via Wiltse approach. Clinical parameters, including visual analogue scale (VAS) of pain, OswestryDability Index (ODI), satisfaction rate were assessed before the operation and at the latest follow-up. The internal fixation and intervertebral fusion were evaluated by X-ray and CT.The data were compared with single sample t test between the two groups. Results: The feasibility of trans longissimus and iliocostalis approach was proved by imaging measurement and anatomic study. The tube's maximum tilt angle in LPA group was 65°, and it was 40°in Wiltse group. There was no significantly difference in the operating time, bleeding and drainage volume between the two groups((120±27) min vs (115±32) min, (104±31) ml vs (110±41) ml, (50±15) ml vs (47±18) ml, respectively, t=1.246,-1.917,1.730,all P>0.05). In both groups, VAS and ODI scores significantly improved at the latest follow-up when compared with those before the operation (all P<0.05), but those were all comparable between the two groups(all P>0.05). The excellent rate of subjective satisfaction for the clinical efficacy in group A and B was 89.6%(43/48) and 86.8%(66/76) respectively (χ(2)=0.208,P>0.05). Conclusions: LPA approachfor microsurgical bilateral decompression via unilateral approach (MBDU) in degenerative lumbar stenosis is safe and effective, it has advantages in direct vison of contralateral nerve root canal decompression for trefoil shaped spinal canal.

RESUMO

BACKGROUND: Microscopic bilateral decompression (MBD) has been suggested as an alternative to open laminectomy and fusion. Recently, percutaneous biportal endoscopic decompression (PBED) has begun to attract attention. The purpose of this retrospective study was to evaluate postoperative pain, functional disability, symptom reduction and satisfaction, and specific surgical parameters between the MBD and PBED techniques in patients with lumbar spinal stenosis (LSS). METHODS: A retrospective review of LSS patients performed with MBD or PBED technique between May 2015 and June 2018 was conducted. Institutional review board approval in People's Hospital of Ningxia Hui Nationality Autonomous Region was obtained prior to conducting chart review and analysis. We received informed consent from all patients before surgery. The primary outcomes assessed were the preoperative to postoperative changes in leg/back pain and disability/function, patient satisfaction with the procedure, and postoperative quality of life. The secondary outcomes including duration of postoperative hospital stay, time to mobilization, postoperative analgesic use, complication rates, and baseline patient characteristics were prospectively collected. RESULTS: The hypothesis was that the PBED technique would achieve better clinical outcomes as compared to the MBD technique in LSS.

RESUMO

Variety of conditions may be responsible for low back pain but lumber spinal canal stenosis is an important cause of low back pain. Lumber spinal canal stenosis usually presents with low backache with neurogenic claudication and shortness of walking distance in adult patient. Surgical management of lumbar spinal canal stenosis by decompression surgery is effective method. This prospective interventional study was performed in patient with clinical features like low back pain with radicular pain, neurogenic claudication, signs of root compression, positive MRI findings attending in department of Orthopaedic Surgery Mymensingh Medical College Hospital and Private Hospital from July 2016 to June 2019. Thirty patients were evaluated among those 20(66.6%) were 50 years and above. The mean age was 47.5±1.6 years. Male to female ratio was roughly 8:1. Almost all of the patients had low backache with radiation to the back of the thigh and leg with motor weakness (60%). About 66.6% of the patients had sensory deficit and 83.3% had neurogenic claudication. Majority (80.0%) of the patients at presentation had a suffering of 12 or >12 months. The mean duration of suffering was 14.7±5.1 months. About 55% of the patients were able to perform heel-walking and 36.0% tip-toe walking. Nearly 57% of the patients had sensory deficit along the distribution of 1st sacral nerve and 53.3% along the distribution of lumber 5 nerves. Diagnosis shows that 16.6% of patients had L4 lesion, 50% L5, 10.0% patients had L4 & L5 and 46.6% S1. Laminectomy was done in 26.6% of patients, laminectomy and disectomy in 33.3% and laminectomy, discectomy & foraminal decompression in 40.0% of patients. Twenty five (83.5%) of patients was free from symptoms. Eighty percent (80.0%) of patients shows minimal disability and 20.0% moderate disability on the basis of Oswestry Disability Index, while by MacNab criteria, most (80%) of patients was excellent, 10% good and another 10% fair. Repeated measure ANOVA statistics showed that mean Oswestry score decreased significantly from 54.5% at baseline to 22% at the end of 1 year (p<0.001).
