Abstract
BACKGROUND Spinal synovial cysts (SSCs) are a rare cause of nerve root and spinal cord compression. Surgical excision of SSCs remains the mainstay of treatment in the presence of unremitting symptoms or neurological deficits, but the choice of the surgical approach remains controversial. The goal of this study was to compare clinical outcomes and adverse events associated with traditional approaches (interlaminar or laminectomy/hemilaminectomy) and minimally invasive approaches (microsurgical tubular approaches or endoscopic approaches) for SSCs. METHODS Studies reporting surgical management of SSCs were searched in three online databases (PubMed, the Cochrane Library, and Web of Science). This meta-analysis was reported following the PRISMA Statement. It was registered at the International Prospective Register of Systematic Reviews (CRD42021288992). The Cochrane Collaboration's Risk of Bias in Nonrandomised Studies-of Interventions (ROBINS-I) was used to evaluate bias. Extracted research data were statistically analyzed using Stata 16 and SPSS statistics 25. RESULTS A total of 22 related relevant studies were included. Meta-analysis revealed no statistically significant difference in dural tear, residual cyst, recurrence, reoperation, and operation time between minimally invasive approaches and traditional approaches (p > 0.05), but minimally invasive approaches had a good functional improvement (p = 0.004). Postoperative length of hospital stays and intraoperative bleeding in traditional approaches were also higher than in minimally invasive approaches (p < 0.05). CONCLUSION Based on the available evidence, minimally invasive approaches may be better than traditional approaches in the treatment of SSCs. Minimally invasive approaches had the advantages of improving clinical satisfaction, with a similar complication rate to traditional approaches. Moreover, endoscopic and microsurgical tubular approaches had similar outcomes.

Abstract
Background Lumbar synovial cysts (LSC), best diagnosed on MR studies, may cause symptoms/signs ranging from unilateral radiculopathy to cauda equina compressive syndromes. Attempts at percutaneous treatment of LSC typically fail. Rather, greater safety/efficacy is associated with direct surgical resection with/without fusion. Methods Treatment of LSC with percutaneous techniques, including cyst aspiration/perforation, injection (i.e., with/without steroids, saline/other), dilatation, and/or disruption/bursting, classically fail. This is because LSCs' tough, thickened, and adherent fibrous capsules cause extensive thecal sac/nerve root compression, and contain minimal central "fluid" (i.e., "crank-case" and non-aspirable). Multiple percutaneous attempts at decompression, therefore, typically cause several needle puncture sites risking dural tears (DT)/cerebrospinal fluid (CSF) leaks, direct root injuries, failure to decompress the thecal sac/nerve roots, infections, hematomas, and over the longer-term, adhesive arachnoiditis. Results Alternatively, many studies document the success of direct or even partial resection of LSC (i.e., partial removal with marked cyst/dural adhesions with shrinking down the remnant of capsular tissue). Surgical decompressions of LSC, ranging from focal laminotomies to laminectomies, may or may not warrant additional fusions. Conclusions Symptomatic LSC are best managed with direct or even partial operative resection/decompression with/without fusion. The use of varying percutaneous techniques classically fails, and increases multiple perioperative risks.

Abstract
The treatment of lumbar spinal synovial cysts (LSCs) which are relatively rare but can cause neurogenic dysfunction and intractable pain has been a controversial topic for many years. Surgical excision of LSCs is the standard treatment for patients in whom conservative treatment options fail. This meta-analysis was undertaken to compare clinical outcomes between minimally invasive approaches using tubular retractors (microscopic vs. endoscopic) and traditional percutaneous approaches for LSCs. Studies reporting surgical management of LSCs were searched in the Cochrane Library, PubMed and Web of Science database. This meta-analysis was reported following the PRISMA Statement, registered in Prospero (CRD42021288992). A total of 1833 patients were included from both the related relevant studies (41 studies, n = 1831) and the present series (n = 2). Meta-analysis of minimally invasive tubular approaches revealed no statistically significant difference in pain improvement, dural tear, residual cyst, recurrence and operation time between minimal groups with traditional groups (p > 0.05). Minimal groups had better Functional improvement of 100% (95% CI 1.00-1.00; p < 0.001, I2 = 75.3%) and less reoperation rates of 0% (95% CI - 0.00-0.00; p = 0.007, I2 = 47.1%). Postoperative length of hospital stay and intraoperative bleeding in minimal groups were also less than traditional groups (p < 0.05). Subgroup analysis revealed endoscopic groups had less operation time (p = 0.004), and there was no significant difference in the rest. For patients with LSCs but without obvious clinical and imaging evidence of vertebral instability, even when preoperative stable grade 1 spondylolisthesis is present, minimally invasive tubular approaches without fusion may provide the best outcome in surgical management.

Abstract
STUDY DESIGN Single-center series. OBJECTIVE Intraspinal facet joint cysts can lead to nerve root compression symptoms with severe discomfort and disability. Permanent improvement can be achieved by surgical resection of the cyst. However, cerebrospinal fluid (CSF) leakage is a common problem in resection of facet joint cyst.The aim of the study was to investigate the frequency of CSF leak after resection of a joint cyst and to determine predictive factors. METHODS A total of 176 consecutive patients underwent surgery for lumbar spinal facet joint cyst in our institution between 1997 and 2018. Patients with a CSF leak were compared with patients without a CSF leak (control group). RESULTS CSF leakage occurred in 14 patients (8.0%) In 2 of the cases (14.3%), the CSF leak was recognized only postoperatively, in 12 cases (85.7%), the CSF leak was detected intraoperatively. Despite intraoperative dura repair, 4 of these 12 patients (33.3%) presented with CSF leakage postoperatively. Altogether 6 patients had postoperative CSF leakage. Compared with patients without CSF leak, there were no differences in preoperative symptoms, surgical technique, complications, or postoperative findings. Adhesion of the cyst to the dura mater was present in all 14 patients with CSF leakage (100%), but only 61.7% of the control group ( P <0.005). All patients in the CSF leak group showed an improvement of their preoperative symptoms. CONCLUSIONS The rate of CSF leakage in resection of spinal facet joint cyst was 8% in the present study. The occurrence of a CSF leakage was independent of clinical factors, level, or side of the cyst, but significantly correlated to dural adhesion of the cyst.Since neither clinical recovery nor recurrence rates do depend on complete removal of the cyst, aggressive resection of dural adherend parts of the cyst wall should be avoided to prevent CSF leakage.

Abstract
OBJECTIVE Lumbar synovial cysts (LSC) are one of the manifestations of spinal degenerative cascade. Spinal stenosis or presence of instability in these patients can lead to various symptoms and surgery is indicated following failure of non-operative management for symptomatic synovial cysts. Surgery when performed consists of either decompression with resection of cyst with our without fusion. The efficacy and complications of minimally invasive techniques using tubular retractors (microscopic or endoscopic) in comparison to traditional open techniques remain to be studied. METHODS A comprehensive search of different databases was performed to retrieve studies describing the use of minimal invasive techniques using tubular retractors (both microscopic and endoscopic) in patients with LSC. Meta-analysis with subgroup analysis and metaregression was done. RESULTS Twenty articles were selected for the systematic review and meta-analysis with total of 388 patients. Eighty-six percent of patients (95% Confidence Interval (CI): 80-90%) had favorable outcome as per Macnab's criteria (excellent and good outcome) with the pooled standard mean difference between preoperative and postoperative Oswestry Disability Index (ODI) being -4.44 (95% CI -8.78 to -0.10, p-value=0.0474, I2 82%). The pooled percentage change in visual analogue scale (VAS) after surgery was 76.5% (95% CI 66.9-84%, I2 82%). The pooled proportion of incidental durotomies, cyst recurrence and patients requiring operation being 8% (95% CI 5-11%, I2 0%), 4% (95% CI 2-7%, I2 0%,) and 5% (95% CI 3-9%) respectively. Studies were homogeneous with an I2 value of 0%. Subgroup analysis revealed no significant difference in the outcome rates or complication rates between the microscopic and endoscopic subgroups. CONCLUSION Minimally invasive techniques for the resection of LSC is a safe and effective alternative to traditional surgical approaches with no difference between the microscopic and endoscopic approaches.

Abstract
Introduction Intraspinal facet cysts resistant to conservative treatment are treated surgically. Surgical treatment was generally resection and decompression, but complications of dural tear and recurrence sometimes occurred. We present good clinical results and rapid spontaneous resolution following treatment of five cases of lumbar intraspinal facet cyst after lateral lumbar interbody fusion (LLIF). Methods Multicenter series of five cases of lumbar intraspinal facet cyst with segmental instability treated with LLIF. The cross-sectional area (CSA) of the thecal sac and facet cyst on T2-weighted axial magnetic resonance imaging and the distance of facet joint (FJ) gap on axial computed tomography were measured preoperatively and postoperatively. Patient data and clinical and radiographic results were described. Results Of five patients, one was male and four were female, with an average age of 72.6 (61-76) years. The mean preoperative CSA of facet cyst was 40.09 mm2. In all cases, intraspinal facet cyst resolved within two weeks after LLIF and good clinical results were obtained. The mean CSA of the thecal sac increased from 64.18 mm2 preoperatively to 95.72 mm2 postoperatively. The mean distance of FJ gap increased from 0.8 (0-1.5) mm preoperatively to 3.1 (0.5-6.0) mm postoperatively. Conclusions LLIF may be indicated for intraspinal facet cysts with segmental instability.

Abstract
BACKGROUND Intraspinal lumbar vertebral joint cysts are an unusual cause of nerve root compression symptoms and do not differ clinically from the symptoms of a herniated disc. PATHOGENESIS The cysts originate from the small vertebral joints and, depending on their size, compress the nerval structures. The affected vertebral joints typically show activated arthritic circumstances, which are associated with degenerative spondylolisthesis in about 50% of cases. In the majority of cases, MRT and CT can be used for diagnostic purposes. The exact etiology has not been fully clarified; various factors such as activated arthritis of the vertebral joints appear to be the major cause. TREATMENT Treatment options include conservative, semi-invasive and surgical therapy. Conservative and semi-invasive treatment methods lead to temporary improvement. The result of surgical treatment, however, is excellent in a complete resection of synovial cysts. In In rare cases, an initial fusion is necessary in rare cases.

Abstract
Spinal synovial cysts (SSC) are a rare but important differential diagnosis for degenerative or space-occupying spinal lesions. There is controversy about the most beneficial treatment, which can be conservative or surgical. We provide a review of our surgical data for purposes of quality assessment and improvement. 5313 patients with surgically treated degenerative spinal diseases were analyzed retrospectively. The incidence of SSC was 1.14%. 61 patients (31 women, 30 men; mean age 65.3 years) with SSC were included in this study. The charts, surgical reports, and radiographic data were reviewed for demographics, duration of symptoms, size of SSC, anatomical site, surgical approach, Visual Analog Scale (VAS), and neurological performance including the Japanese Orthopedic Association Score (JOA score) and the Frankel score. Laminotomy was the most common surgical approach in 93.4% of the patients followed by hemilaminectomy in 6.6%. The predominant site of SSC was the lumbar spine in 86.9%. 95.1% had experienced local and radicular pain as the predominant symptom and 47.5% preoperative sensory and motor deficits. At discharge, the JOA score was significantly increased compared to admission (median value of 17). At follow-up, 94.4% had normal neurological function and 5.6% showed grade 1 neurological deficits. Leg pain had decreased in 94.4% and back pain in 70.6%. At long-term follow-up, all patients presented neurologically stable. The median value for pain classified with the VAS had decreased from 6 at admission to 1 at long-term follow-up. During long-term follow-up, 6 patients (9.8%) had developed spinal instability requiring stabilization, 5 patients had received facet joint infiltration due to symptomatic facet joint syndrome. The epidemiological and clinical patterns of symptomatic SSC are similar to those of other degenerative spinal diseases. Thus, SSC should always be considered as a rare but important differential diagnosis. Surgical outcome was excellent with immediate symptom relief and recovery, which further improved over time. Our data support the benefit of surgical treatment and may be useful in recommending neurosurgical therapy to patients with SSC.

Abstract
Background In this new section, Case of the Month with Short Perspective from Surgical Neurology International, we want to see how various spine surgeons would approach different spinal pathologies. In this first case, an elderly male presented with 3 years of lower back pain and progressive neurogenic claudication with bilateral radiculopathy that had exacerbated over the prior 6 months. An outside physician performed a magnetic resonance (MR) study of the lumbar spine that showed a massive synovial cyst filling the spinal canal (e.g., large bilateral cysts) at the L3-L4 level with grade I spondylolisthesis. The MR and CT studies also both demonstrated moderate L2-L3, and severe L3-L4 stenosis. Methods Despite the massive synovial cyst filling the spinal canal at the L3-L4 level, pain management (anesthesia training) spent 3 months performing three successive epidural steroid injections accompanied by attempts at percutaneous synovial cyst aspiration/rupture. Results By the time the patient presented to neurosurgery, he had developed severe neurogenic claudication, radiculopathy, myelopathy, and a cauda equina syndrome. Dynamic X-rays revealed a mild grade I degenerative spondylolisthesis at the L3-L4 level without active motion, while both computed tomography (CT) and MR studies confirmed moderate stenosis stenosis/ossification of the yellow ligament at the L2-L3 level, severe stenosis at L3-L4 level with spondylolisthesis, and massive bilateral synovial cysts at the L3-L4 level filling the spinal canal. Conclusions Following an L2-L4 decompressive laminectomy without fusion (note the absence of motion intraoperatively at the L3-L4 level), the patient's symptoms resolved, and he regained normal function. How would you have managed this patient?

Abstract
BACKGROUND With the aging of our society comes a rising number of elderly patients with progressive degeneration of the spine associated with synovial cysts. Surgical treatment may be particularly challenging in elderly patients because of comorbidities. METHODS Patients treated in our department between 1999 and 2014 for spinal synovial cysts were screened. The 28 patients ≥75 years old were classified as elderly and were compared with 96 patients 50-74 years old. No patient underwent fusion as part of cyst resection. RESULTS Despite a significantly higher frequency of muscle reflex changes in elderly patients at presentation, symptoms, cyst levels, rate of complications, and surgical method were not different between groups. Cyst adherence to the dura and subtotal resection were observed significantly more often in the elderly group (18% vs. 3%; P < 0.05). Outcome according to the Oswestry Disability Index was classified as no disability or minimal disability in 85% of the elderly group and in 82% of the control group. Recurrent cyst and delayed fusion rates were lower in the elderly group (4% and 4%) compared with the control group (7% and 8%). CONCLUSIONS The clinical course of elderly patients with surgical treatment of spinal synovial cysts did not differ compared with younger patients. Good or excellent results could be achieved and persisted for a long time in most cases. Fusion should be performed only in cases of severe instability. Nonaggressive cyst removal in cases of dural attachment enables low cerebrospinal fluid fistula rates without increasing cyst recurrence rates.

Abstract
OBJECTIVE Synovial cysts of the spine are rare lesions, predominantly arising in the lumbar region. Despite their generally benign behavior, they can cause severe symptoms due to compression of neural structures in the spinal canal. Treatment strategies are still a matter of discussion. The authors performed a single-center survey and literature search focusing on long-term results after minimally invasive surgery. METHODS A total of 141 consecutive patients treated for synovial cysts of the lumbar spine between 1997 and 2014 in the authors' department were analyzed. Medical reports with regard to signs and symptoms, operative findings, complications, and short-term outcome were reviewed. Assessment of long-term outcome was performed with a standardized telephone questionnaire based on the Oswestry Disability Index (ODI). Furthermore, patients were questioned about persisting pain, symptoms, and further operative procedures, if any. Subjective satisfaction was classified as excellent, good, fair, or poor based on the Macnab classification. RESULTS The approach most often used for synovial cyst treatment was partial hemilaminectomy in 70%; hemilaminectomy was necessary in 27%. At short-term follow-up, the presence of severe and moderate leg pain had decreased from 93% to 5%. The presence of low-back pain decreased from 90% to 5%. Rates of motor and sensory deficits were reduced from 40% to 14% and from 45% to 6%, respectively. The follow-up rate was 58%, and the mean follow-up period was 9.3 years. Both leg pain and low-back pain were still absent in 78%. Outcome based on the Macnab classification was excellent in 80%, good in 14%, fair in 1%, and poor in 5%. According to the ODI, 78% of patients had no or only minimal disability, 16% had moderate disability, and 6% had severe disability at the time of follow-up. In this cohort, 7% needed surgery due to cyst recurrence, and 9% required a delayed stabilization procedure after the initial operation. CONCLUSIONS Surgical treatment with resection of the cyst provides favorable results in outcome. Excellent or good outcome persisting for a long-term follow-up period can be achieved in the vast majority of cases. Complication rates are low despite an increased risk of dural injury. With facet-sparing techniques, the stability of the segment can be preserved, and resection of spinal synovial cysts does not necessarily require segmental fusion.

Abstract
Lumbar facet cysts are a rare but increasingly common cause of symptomatic nerve root compression and can lead to radiculopathy, neurogenic claudication, and cauda equina syndrome. The cysts arise from the zygapophyseal joints of the lumbar spine and commonly demonstrate synovial herniation with mucinous degeneration of the facet joint capsule. Lumbar facet cysts are most common at the L4-L5 level and often are associated with spondylosis and degenerative spondylolisthesis. Advanced imaging studies have increased diagnosis of the cysts; however, optimal treatment of the cysts remains controversial. First-line treatment is nonsurgical management consisting of oral NSAIDs, physical therapy, bracing, epidural steroid injections, and/or cyst aspiration. Given the high rate of recurrence and the relatively low satisfaction with nonsurgical management, surgical options, including hemilaminectomy or laminotomy to excise the cyst and decompress the neural elements, are typically performed. Recent studies suggest that segmental fusion of the involved levels may decrease the risks of cyst recurrence and radiculopathy.

Intraspinal Lumbar Juxtaarticular Cyst Treatment Through CT-Guided Percutaneus Induced Rupture Results in a Favorable Patient Outcome. Clin Pract 2016; 6:866. [PMID: 27994840 PMCID: PMC5136736 DOI: 10.4081/cp.2016.866] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Revised: 10/10/2016] [Accepted: 10/11/2016] [Indexed: 01/28/2023] Open
Abstract
Juxta-articular cysts are synovial cysts originating from the facet joints or the flava ligaments. If they grow intra-spinally they can compress nervous structures and cause a variety of symptoms. Micro-neurosurgery is usually the treatment of choice. Alternatively to surgical treatment the cyst can be approached and treated with a CT guided percutaneous injection inducing rupture. After fulfilling strict selection criteria twenty patients (25% of all treated lumbar synovial cyst patients), were treated minimally invasive by this method from 2010-2016. The facet joint was punctured under CT guidance and a mixture of a local anesthetic and contrast liquid was injected until the cyst was blasted. The mean follow-up period was 1.1 years (range 2 weeks - 5 years). Fifteen of twenty procedures were successful and cyst rupture was confirmed by CT-scans. Twelve of these fifteen patients experienced a significant improvement of their symptoms and needed no further intervention or surgical procedure up until now, three patients showed no clinical improvement and were treated surgically within one week after cyst rupture. In five patients it was technically not possible to rupture the cyst. These patients were treated microsurgically by cyst resection and dynamic stabilization or fusion procedures. The percutaneus rupture of juxtaarticular cysts has fewer risks and is cost effective compared to microsurgical resection. It may be an alternative to surgical treatment for a selected group of patients. However there are some limitations to the procedure though, such as difficult patient selection, unpredictable outcome or technical problems due to highly degenerated facet joints.

Epstein NE. Incidence and management of cerebrospinal fluid fistulas in 336 multilevel laminectomies with noninstrumented fusions. Surg Neurol Int 2015; 6:S463-8. [PMID: 26605107 PMCID: PMC4617028 DOI: 10.4103/2152-7806.166874] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2015] [Accepted: 07/13/2015] [Indexed: 11/22/2022] Open
Abstract
Background: The incidence (e.g., 3–27%) and the types of cerebrospinal fluid (CSF) fistulas occurring during multilevel lumbar laminectomy with noninstrumented spinal fusions varies. Methods: From 2000 to 2015, we retrospectively evaluated the incidence/etiologies of CSF fistulas occurring for 336 patients undergoing average 4.7 laminectomies with average 1.4 level noninstrumented fusions over a 15 year period. The varied etiologies of CSF leaks included; ossification of the yellow ligament (OYL) extending through the dura, postoperative surgical scar, iatrogenic traumatic leak, epidural steroid injections (ESI), resection of synovial cysts, and the removal of intradural tumors. Techniques for primary repairs included combinations of; 7-0 Gore-Tex (Newark, Delaware, USA) sutures, micro-dural staples, muscle patch/other (e.g., bovine pericardial) grafts, fibrin sealants/glues (e.g., Tisseel; Baxter International Inc., Westlake Village, CA, USA), and Duragen (Integra LifeSciences, Hawthorne, NY, USA) including both the thin and suturable types. Results: The etiologies of CSF fistulas in descending order included: Epidural spinal injections (ESI) (7 patients), synovial cysts (6 patients), OYL (5 patients), and equally for postoperative scar and intradural tumors (3 patients). CSF fistulas occurred in 24 (7.14%) of 336 patients; this frequency was reduced to 4.2% when ESI and intradural tumors were excluded. Conclusion: CSF fistulas occurred in 7.14% of 336 patients undergoing average 4.7 multilevel laminectomies with average 1.4 level noninstrumented fusions attributed to a lumbar stenosis with mild/moderate instability. The dural repair addressed seven prior ESI, six synovial cysts, five OYL, and operative scarring and intradural tumors (three apiece). Knowing the pathologies contributing to CSF fistulas should help the surgeon to better anticipate and treat these fistulas.
