Minimally invasive surgical (MIS) approaches have gained popularity in many surgical fields. Potential advantages to a minimally invasive, spinal intradural approach include decreased operative blood loss, shorter hospitalization, and less post-operative pain. Potential disadvantages include longer operative times, decreased exposure, and difficulty closing the dura. Prior case series from our group and others have demonstrated successful tumor resections using MIS techniques without increased complications. In this 3D video, we demonstrate the key steps in our mini-open, transpinous approach for the resection of an intradural, extramedullary lumbar schwannoma. This operation is performed through a midline incision confined to one or two levels. The spinous process is removed. The paraspinal muscles are spread using a series of sequentially larger tubular dilators, and the first dilator is placed in the space previously occupied by the target level spinous process. The expandable tube retractor is then placed over the largest dilator and docked into place over the target laminae. The expandable tubular retractor is 6 centimeters in depth and 2.5 centimeters in width before expansion and is adjustable to 9 centimeters in depth and 4–5 centimeters in diameter which allows removal of intradural lesions confined to one or two spinal segments.

Minimally invasive surgical (MIS) approaches are gaining popularity in many surgical fields. Potential advantages include reduced blood loss, shorter length of stay, and less soft-tissue trauma. Potential disadvantages include inadequate deformity correction, increased fluoroscopy, longer operative times, and decreased posterolateral fusion surface area exposure.This video demonstrates the key steps in our mini-open transforaminal lumbar interbody fusion (TLIF) using an expandable tubular retractor, placement of cannulated pedicle instrumentation, and subsequent deformity correction. The video demonstrates positioning, surgical opening through a midline incision, a bilateral Wiltse plane tubular approach for the TLIF, placement of bilateral cannulated pedicle screws, and deformity correction.The video can be found here: http://youtu.be/Jj7w4i2DTMQ.

Abstract Background Completely extradural spinal schwannomas have a unique morphology (dumbbell tumors) with an intra- and extraspinal component. When they compromise two contiguous vertebral bodies or have an extraspinal extension >2.5 cm, they are classified as giant spinal schwannomas. The aim of this study is to present our experience in the surgical management of completely extradural giant spinal schwannomas with a minimally invasive approach. Methods This study is a case series of patients treated at the Neurosurgery Department of the University Clinical and Provincial Hospital of Barcelona, Spain, between January 2016 and December 2019. Results Fifteen patients met the inclusion criteria, with thoracic and lumbar spines being the most frequent locations. All patients underwent surgical treatment, with a mini-open interlaminar and far-lateral technique. Total gross resection was accomplished in all patients and spine instrumentation was not necessary. Conclusions Microsurgery is the treatment of choice for spinal schwannomas, and gross total resection with low morbidity must be the surgical goal. Mini-open interlaminar and far-lateral access is a valid surgical option, with low morbidity in experienced hands, and there is no need for spinal instrumentation.

AbstractAn increasing incidence of sacral insufficiency fractures in geriatric patients has been documented, representing a major challenge to our healthcare system. Determining the accurate diagnosis requires the use of sectional imaging, including computed tomography and magnetic resonance imaging. Initially, non-surgical treatment is indicated for the majority of patients. If non-surgical treatment fails, several minimally invasive therapeutic strategies can be used, which have shown promising results in small case series. These approaches are sacroplasty, percutaneous iliosacral screw fixation (S1 with or without S2), trans-sacral screw fixation or implantation of a trans-sacral bar, transiliac internal fixator stabilisation, and spinopelvic stabilisation. These surgical strategies and their indications are reported in detail. Generally, treatment-related decision making depends on the clinical presentation, fracture morphology, and attending surgeonʼs experience.

Study Design: Retrospective case series. Objective: Posterior surgery for thoracic disc herniation was associated with increased morbidity and mortality and new minimally invasive approaches have been recommended for soft disc herniation but not for calcified central disc. The objective of this study is to describe a posterolateral microscopic transpedicular approach for central thoracic disc herniation. Methods: This is a single center retrospective review of all the cases of giant thoracic calcified disc herniation as defined by Hott et al. Presence of myelopathy, percentage of canal compromise, T2 hypersignal, ASIA score, and ambulatory status were recorded. This posterolateral technique using a tubular retractor was thoroughly described. Results: Eight patients were operated upon with a mean follow-up of 16 months. Mean canal compromise was 61%. Mean operative time was 228 minutes and mean operative bleeding was 250 mL. There were no cases of dural tear or neurologic degradation. Conclusion: This is the first report of posterior minimally invasive transpedicular approach for giant calcified disc herniation. There were neither cases of neurological deterioration nor increased rate of dural tears. This technique is thus safe and could be recommended for treatment of this rare disease.

OBJECTIVE Minimally invasive posterior cervical decompression (miPCD) has been described in several case series with promising preliminary results. The object of the current study was to compare the clinical outcomes between patients undergoing miPCD with anterior cervical discectomy and instrumented fusion (ACDFi). METHODS A retrospective study of 74 patients undergoing surgery (45 using miPCD and 29 using ACDFi) for myelopathy was performed. Outcomes were categorized into short-term, intermediate, and long-term follow-up, corresponding to averages of 1.7, 7.7, and 30.9 months, respectively. Mean scores for the Neck Disability Index (NDI), neck visual analog scale (VAS) score, SF-12 Physical Component Summary (PCS), and SF-12 Mental Component Summary (MCS) were compared for each follow-up period. The percentage of patients meeting substantial clinical benefit (SCB) was also compared for each outcome measure. RESULTS Baseline patient characteristics were well-matched, with the exception that patients undergoing miPCD were older (mean age 57.6 ± 10.0 years [miPCD] vs 51.1 ± 9.2 years [ACDFi]; p = 0.006) and underwent surgery at more levels (mean 2.8 ± 0.9 levels [miPCD] vs 1.5 ± 0.7 levels [ACDFi]; p < 0.0001) while the ACDFi patients reported higher preoperative neck VAS scores (mean 3.8 ± 3.0 [miPCD] vs 5.4 ± 2.6 [ACDFi]; p = 0.047). The mean PCS, NDI, neck VAS, and MCS scores were not significantly different with the exception of the MCS score at the short-term follow-up period (mean 46.8 ± 10.6 [miPCD] vs 41.3 ± 10.7 [ACDFi]; p = 0.033). The percentage of patients reporting SCB based on thresholds derived for PCS, NDI, neck VAS, and MCS scores were not significantly different, with the exception of the PCS score at the intermediate follow-up period (52% [miPCD] vs 80% [ACDFi]; p = 0.011). CONCLUSIONS The current report suggests that the optimal surgical strategy in patients requiring dorsal surgery may be enhanced by the adoption of a minimally invasive surgical approach that appears to result in similar clinical outcomes when compared with a well-accepted strategy of ventral decompression and instrumented fusion. The current results suggest that future comparative effectiveness studies are warranted as the miPCD technique avoids instrumented fusion.

This video demonstrates the minimally invasive surgical technique used in a 56-year-old woman suffering from L-5 spondylolysis and grade 2 L5–S1 spondylolisthesis. The first author used expandable tubular retractors bilaterally to perform neural decompression, mini-open TLIF, spondylolysthesis reduction and L5–S1 pedicle screw fixation. L-5 cement augmentation was performed through cannulated and fenestrated screws to enhance resistance to screw pull-out secondary to reduction maneuvers.Sequential surgical steps related to microsurgery, spondylolysthesis reduction and instrumentation are shown and commented.We submit that in cases of lythic spondylolisthesis a bilateral traversing and exiting nerve roots decompression is a safer option prior to performing the deformity reduction and fixation; the proposed minimally invasive technique may help in reducing surgical morbidity and improving postoperative recovery.The video can be found here: http://youtu.be/G4Qdg-A-Y3M.

Abstract OBJECTIVE Synovial cysts are a rare cause of lumbar radiculopathy and back pain. Surgical treatment is directed at complete excision of the cyst. We used minimally invasive surgical techniques for a series of patients, to assess the effectiveness of this approach for resection of synovial cysts. METHODS Seventeen patients (10 female and 7 male patients) with presumed synovial cysts, as indicated on magnetic resonance imaging scans, underwent surgical resection with the 18-mm METRx tubular retractor system (Medtronic Sofamor Danek, Memphis, TN). A unilateral approach was used, with either an operating microscope (13 cases) or a magnifying endoscope (4 cases), depending on the preference of the surgeon. Outcomes were reported by using modified MacNab criteria. RESULTS The average patient age was 64 years (range, 46–82 yr). The L4–L5 level was most commonly affected (82% of cases). Grade 1 spondylolisthesis at the level harboring the synovial cyst was observed for 47% of the patients; all cases of spondylolisthesis involved the L4–L5 level. The mean operative time was 97 minutes, and the average blood loss was 35 ml. Excellent or good results were achieved for 94% of the patients. A dural tear that did not violate the arachnoid membrane occurred during surgery for one patient but did not require further treatment. CONCLUSION Synovial cysts can be effectively treated with a tubular retractor system in conjunction with an endoscope or microscope. Use of the tubular retractor minimizes soft-tissue trauma, incision length, blood loss, and disruption of ligamentous and bony structures. This may be particularly significant when synovial cysts are associated with spondylolisthesis, minimizing the risk of progressive instability and the need for fusion.
