OBJECTIVEMinimally 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).METHODSA 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.RESULTSBaseline 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).CONCLUSIONSThe 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.
A retrospective study of thirteen patients undergoing 5-level anterior spinal surgery for cervical myelopathy.Objective: While limited literature exists in reviewing the treatment of high cervical pathology extending caudally, we believe long segment surgery beginning at C2-3 can be accomplished with good success and is an option more patients may benefit from. We aim to describe the technique in accessing the C2-C3 disk space and efficacy of treating multilevel disease beginning at the C2 vertebral body. This includes an extensive technical report and surgical pearls.Summary of Background Data: Compression at the level of C2 can be daunting to access because of steep approach required. Few studies have described the technique in reaching the C2 level, with less information describing the efficacy of a 5-level anterior fusion starting at C2. Methods: Patients who underwent surgery between 2000 and 2016 were identified utilizing the department billing database and ICD codes. Patients age, operative indications, levels treated, length of hospital stay, fusion outcome, and operative complications were explored. Independent analysis of fusion was performed.
Results:The average length of hospital stay was 3.9 days. Eight patients reported significant improvement of hand weakness, numbness, and/or gait at 6 months follow-up. The most frequent complication was dysphagia (23%). One patient experienced recurrent symptoms secondary to nonunion, and another patient suffered a postoperative neurological worsening because of anterior spinal artery syndrome.
Conclusion:This retrospective review discusses the technique to visualize and fully decompress C2-C3 spinal segments. In addition, we explored the efficacy and perioperative risk in long segment anterior cervical discectomy and fusion.
Spinal fractures often have devastating sequelae. Thoracolumbar fractures are classified using the Thoracolumbar Injury Classification and Severity score (TLICS) to determine the severity of injury and to guide treatment. Recently advancements in minimally invasive spine surgery (MISS) have led to new approaches to high-severity fractures. Studies have suggested that MISS may yield similar outcomes to conventional, more invasive procedures while producing several benefits. Methods: This retrospective study involves 46 patients treated from 2005 through 2020 for high grade thoracolumbar trauma from T2 to L5 with a minimum follow-up of 6-months treated with MISS techniques using percutaneous instrumentation. Results: Average TLICS was 7.5. Patient derived outcome measures with average length of follow-up of 602 days included Oswestry Disability Index 28.9, Patient Satisfaction Index 4.2, Short Form-12 Mental Component Score 51.9, and Short Form-12 Physical Component Score 37.7. Average estimated blood loss was 119.2 mL.
Conclusion:The TLICS is a validated tool used to guide surgical intervention in high grade trauma. The utilization of MISS techniques for the treatment and stabilization of thoracolumbar trauma is efficacious and a viable alternative to traditional open approaches.
BACKGROUND: Spinal cord stimulation (SCS) is a safe neuromodulatory treatment used to treat failed back surgery syndrome, chronic neuropathic pain, and complex regional pain syndrome. Despite its efficacy, some patients fail to achieve pain relief and elect to undergo removal of SCS paddle leads. The safety and best practices of these procedures have not been defined. OBJECTIVE: In this article, we describe our technique and complication rate in a series of SCS paddle removals. METHODS: All patients who underwent SCS paddle removal at the Albany Medical Center between 2011 and 2020 were identified. Medical charts were reviewed for demographic data, operative technique, and incidence of complications within 30 days of the procedure. RESULTS: Thirty-two (91%) patients underwent a thoracic paddle removal, whereas 3 (9%) underwent a cervical paddle removal. All cases underwent preoperative imaging with computed tomography or MRI, and all cases were performed with neuromonitoring and fluoroscopy. The technique required for paddle removal depended on the extent of local scar formation and ranged from soft tissue dissection to additional laminectomy at an adjacent level. Cases took on average 2 ± 0.09 hours with 23.21 ± 4.29 cc blood loss. Two patients had superficial infections, which were cleared with 1 week of oral antibiotics. There were no other adverse events. CONCLUSION: Thirty-five patients successfully underwent paddle removal with the minor complications reported. In this article, we show that by using neuromonitoring, fluoroscopy, and the techniques described, SCS paddle removal can be performed with minimal risk.
