Iliac Screw

Minimally invasive spinal instrumentation techniques have evolved tremendously over the past decade. Although there have been numerous reports of lumbar instrumentation performed via a percutaneous or minimal incisional route, to date there have been no reports of minimally invasive iliac screw placement. A method was developed for accurate placement of minimally invasive iliac screw placement based on a modification of currently available percutaneous lumbar instrumentation techniques. The method involves fluoroscopically guided insertion of a cannula-based screw system, and this technique was successful applied to treat an L-5 burst fracture with L-4 to iliac spinal stabilization via a minimally invasive approach. This report demonstrates the feasibility of percutaneous iliac screw instrumentation. However, future studies will be needed to validate the safety and efficacy of this approach.

Abstract OBJECTIVE To demonstrate the feasibility of and initial clinical experience with a novel minimally invasive posterolateral thoracic corpectomy technique. METHODS Seven procedures were performed on 6 cadavers to determine the feasibility of thoracic corpectomy using a minimally invasive approach. The posterolateral thoracic corpectomies were performed with expandable 22 mm diameter tubular retractor paramedian incisions. The posterolateral aspects of the vertebral bodies were accessed extrapleurally, and complete corpectomies were performed. Intraprocedural fluoroscopy and postoperative computed tomography were used to assess the degree of decompression. In addition, 2 clinical cases of T6 burst fracture, 1 T4–T5 plasmacytoma, and 1 T12 colon cancer metastasis were treated using this minimally invasive approach. RESULTS In the cadaveric study, an average of 93% of the ventral canal and 80% of the corresponding vertebral body were removed. The pleura and intrathoracic contents were not violated. Adequate exposure was obtained to allow interbody grafting between the adjacent vertebral bodies. The procedures were successfully performed in the 4 clinical cases using a minimally invasive technique, and the patients demonstrated good outcomes. CONCLUSION Based on this study, minimally invasive posterolateral thoracic corpectomy safely and successfully allows complete spinal canal decompression without the tissue disruption associated with open thoracotomy. This approach may improve the complication rates that accompany open or even thoracoscopic approaches for thoracic corpectomy and may even allow surgical intervention in patients with significant comorbidities.

ObjectiveRecent studies have investigated the role of spinal image guidance for pedicle screw placement. Many authors have observed an elevated placement accuracy and overall improvement of outcome measures. This study assessed a bi-institutional experience following introduction of the Renaissance miniature robot for spinal image guidance in Europe.MethodsThe medical records and radiographs of all patients who underwent robot-guided implantation of spinal instrumentation using the novel system (between October 2011 and March 2015 in Mainz and February 2014 and February 2016 in Regensburg) were reviewed to determine the efficacy and safety of the newly introduced robotic system. Screw position accuracy, complications, exposure durations to intraoperative radiation, and reoperation rate were assessed.ResultsOf the 413 surgeries that used robotic guidance, 406 were via a minimally invasive approach. In 7 cases the surgeon switched to conventional screw placement, using a midline approach, due to referencing problems. A total of 2067 screws were implanted using robotic guidance, and 1857 screws were evaluated by postoperative CT. Of the 1857 screws, 1799 (96.9%) were classified as having an acceptable or good position, whereas 38 screws (2%) showed deviations of 3–6 mm and 20 screws (1.1%) had deviations > 6 mm. Nine misplaced screws, implanted in 7 patients, required revision surgery, yielding a screw revision rate of 0.48% of the screws and 7 of 406 (1.7%) of the patients. The mean ± SD per-patient intraoperative fluoroscopy exposure was 114.4 (± 72.5) seconds for 5.1 screws on average and any further procedure required. Perioperative and direct postoperative complications included hemorrhage (2 patients, 0.49%) and wound infections necessitating surgical revision (20 patients, 4.9%).ConclusionsThe hexapod miniature robotic device proved to be a safe and robust instrument in all situations, including those in which patients were treated on an emergency basis. Placement accuracy was high; peri- and early postoperative complication rates were found to be lower than rates published in other series of percutaneous screw placement techniques. Intraoperative radiation exposure was found to be comparable to published values for other minimally invasive and conventional approaches.

Abstract INTRODUCTION Posterior spinal instrumentation for fusion using intraoperative computed tomography (CT) navigation is gaining traction as an alternative to the conventional two-dimensional fluoroscopic-guided approach to percutaneous pedicle screw placement. However, few studies to date have directly compared outcomes of these 2 minimally invasive instrumentation methods. METHODS A consecutive cohort of patients undergoing primary percutaneous posterior lumbar spine instrumentation for spine fusion was retrospectively reviewed. Revision surgeries or cases converted to open were excluded. Accuracy of screw placement was assessed using a postoperative CT scan with blinding to the surgical methods used. The Gertzbein-Robbins classification was used to grade cortical breach: Grade 0 (<0 mm cortical breach), Grade I (<2 mm), Grade II (2-4 mm), Grade III (4-6 mm), and Grade IV (>6 mm). RESULTS CT navigation was found to significantly improve accuracy of screw placement (P < .022). There was significantly more facet violation of the unfused level in the fluoroscopy group vs the CT group (9% vs 0.5%; P < .0001). There was also a higher proportion of poor screw placement in the fluoroscopy group (10.1% vs 3.6%). No statistical difference was found in the rate of tip breach, inferomedial breach, or lateral breach. Regression analysis showed that fluoroscopy had twice the odds of incurring poor screw placement as compared to CT navigation. CONCLUSION This radiographic study comparing screw placement in minimally invasive fluoroscopy- vs CT navigation-guided lumbar spine instrumentation provides evidence that CT navigation significantly improves accuracy of screw placement, especially in optimizing the screw trajectory so as to avoid facet violation. Long-term follow-up studies should be performed to ascertain whether this difference can contribute to an improvement in clinical outcomes.

Over the past few decades, majority of neurosurgeons only specialize in spinal cord diseases. However, with the advances in spine surgery, more and more neurosurgeons focus on spine diseases. Precision minimally invasive technique in surgery of spine and spinal cord is an important branch of neurosurgery. As traditional surgery has been gradually replaced by precision surgery, open surgery has been gradually replaced by minimally invasive surgery (MIS), the diagnosis and treatment of spine diseases has been benefiting from minimally invasive techniques. With minimal surgical trauma, precise localization, MIS has become the inevitable trend of new neurosurgery. The model of multidisciplinary team is gradually becoming universal in the world in order to make the best treatment plan for the patient with spine diseases on the basis of the comprehensive disciplinary opinion.

OBJECT The purpose of this study was to assess the effectiveness and safety of an alternative minimally invasive technique for the treatment of carpal tunnel syndrome (CTS). METHODS This was designed as a prospective, randomized, open-label, blinded end point evaluation (PROBE) study. The active comparison was double tunnels technique (DTT) (Group A, 110 patients) versus standard open decompression of the median nerve (control [Group B], 110 patients). Patient recruitment started in January 2011. The primary outcomes were the functional Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ) scores and visual analog scale (VAS) scores for pain (pVAS) at Weeks 2 and 4, and at Months 3, 6, and 12. The secondary outcome was the aesthetics (aVAS) score at Weeks 2 and 4, and at Months 3, 6, and 12. RESULTS The Student t-test and ANOVA were used, and the results were considered statistically significant if the p value was ≤ 0.05 for continuous variables. The DTT is a tissue-sparing approach that allows the surgeon to limit the length of the incision (0.6 ± 0.05 cm) and to respect the palmar fascia and the subcutaneous tissue. Recovery from wrist pain, night pain, numbness, stiffness, and weakness was achieved more effectively and quickly compared with the standard approach. Better BCTSQ, pVAS, and aVAS scores were observed in Group A. CONCLUSIONS The DTT is a safe and effective approach for the treatment of CTS. This technique entails faster recovery times, better aesthetic outcomes, and lower risks of complications.

Abstract BACKGROUND Epidural spinal cord compression (ESCC) is a common and severe cause of morbidity in cancer patients. Minimally invasive surgical techniques may be utilized to preserve neurological function and permit the use of radiation to maximize local control. Minimally invasive techniques are associated with lower morbidity. OBJECTIVE To describe a novel, minimally invasive operative technique for the management of metastatic ESCC. METHODS A minimally invasive approach was used to cannulate the pedicles of the thoracic vertebrae, which were then held in place by Kirschner wires (K-wires). Following open decompression of the spinal cord, cannulated screws were placed percutaneously with stereotactic guidance through the pedicles followed by cement induction. Stereotactic radiosurgery is performed in the postoperative period for residual metastatic disease in the vertebral body. RESULTS The minimally invasive technique used in this case reduced tissue damage and optimized subsequent recovery without compromising the quality of decompression or the extent of metastatic tumor resection. Development of more minimally invasive techniques for the management of metastatic ESCC has the potential to facilitate healing and preserve quality of life in patients with systemic malignancy. CONCLUSION ESCC from vertebral metastases poses a challenge to treat in the context of minimizing potential risks to preserve quality of life. Percutaneous pedicle screw fixation with cement augmentation provides a minimally invasive alternative for definitive treatment of these patients.

Several surgical options have been described to manage persistent dorsiflexion contracture at the metatarsophalangeal joint and plantarflexion contracture at the proximal interphalangeal joint of the fifth toe. We describe a minimally invasive technique for the management of this deformity. We perform a plantar closing wedge osteotomy of the 5th toe at the base of its proximal phalanx associated with a lateral condylectomy of the head of the proximal phalanx and at the base of the middle phalanx. Lastly, a complete tenotomy of the deep and superficial flexor tendons and of the tendon of the extensor digitorum longus is undertaken. Correction of cock-up fifth toe deformity is achieved using a minimally invasive approach.

Abstract Background This study was conducted to optimize the surgical procedures for single-port thoracoscopic esophagectomy, and to explore its potential advantages over multi-port minimally invasive esophagectomy. Methods For single-port thoracoscopic esophagectomy, the patient was placed in left lateral-prone position and a 4-cm incision through the 4th-5th intercostal space was taken on the postaxillary line. The 10-mm camera and two or three surgical instruments were used for the VATS esophagectomy and radical mediastinal lymph node dissection. The camera position was different for the upper and lower mediastinal regions. Mobilization of stomach was conducted via multiple-port laparoscopic approach. Cervical end-to-side anastomosis was completed by hand-sewn procedures.A propensity-matched comparison was made between the single-port and four-port thoracoscopic esophagectomy groups. Results From 2014 to 2016, 56 matched patients were analyzed. There was no conversion to open surgery or operative mortality. The use of single-port thoracoscopic esophagectomy increased the length of operation time in comparison with using multiple-port minimally invasive technique (mean, 257 vs. 216 min, P = 0.026). The time taken for thoracic procedure in the single-port group was significant longer that in the multi-port group (mean, 126 vs. 84 min, P < 0.001). There were no significant differences between groups in the number of lymph nodes dissected, blood loss, complications or hospital stay (P > 0.05). In single-port thoracoscopic group, the pain in the abdomen was more severe than that in the chest (P = 0.042). The pain scores for postoperative day 1 and day 7 were significantly lower in the single-port group as compared with multiple-port group (P = 0.038 and P < 0.001), a similar trend could be seen for the pain score on postoperative day 3 (P = 0.058). Conclusion Single-port thoracoscopic esophagectomy contributes to reducing postoperative pain with an acceptable increase of operation time, which does not compromise surgical radicality and has similar short-term postoperative outcomes when compared with multiple-port minimally invasive approach.

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.
