Does the Spine Surgeon’s Experience Affect Fracture Classification, Assessment of Stability, and Treatment Plan in Thoracolumbar Injuries?

Study Design: Prospective survey-based study. Objectives: The AO Spine thoracolumbar injury classification has been shown to have good reproducibility among clinicians. However, the influence of spine surgeons’ clinical experience on fracture classification, stability assessment, and decision on management based on this classification has not been studied. Furthermore, the usefulness of varying imaging modalities including radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) in the decision process was also studied. Methods: Forty-one spine surgeons from different regions, acquainted with the AOSpine classification system, were provided with 30 thoracolumbar fractures in a 3-step assessment: first radiographs, followed by CT and MRI. Surgeons classified the fracture, evaluated stability, chose management, and identified reasons for any changes. The surgeons were divided into 2 groups based on years of clinical experience as \u3c10 years (n = 12) and \u3e10 years (n = 29). Results: There were no significant differences between the 2 groups in correctly classifying A1, B2, and C type fractures. Surgeons with less experience hadmore correct diagnosis in classifyingA3 (47.2% vs 38.5%in step 1, 73.6% vs 60.3% in step 2 and 77.8% vs 65.5% in step 3), A4 (16.7% vs 24.1% in step 1, 72.9% vs 57.8% in step 2 and 70.8% vs 56.0%in step3) and B1 injuries (31.9% vs 20.7% in step 1, 41.7% vs 36.8% in step 2 and 38.9% vs 33.9% in step 3). In the assessment of fracture stability and decision on treatment, the less and more experienced surgeons performed equally. The selection of a particular treatment plan varied in all subtypes except in A1 and C type injuries. Conclusion: Surgeons’ experience did not significantly affect overall fracture classification, evaluating stability and planning the treatment. Surgeons with less experience had a higher percentage of correct classification in A3 and A4 injuries. Despite variations between them in classification, the assessment of overall stability and management decisions were similar between the 2 groups. © The Author(s) 2017

A Two-year Outcome of Various Techniques of Discectomy On Complications: A Multicentric Retrospective Study

Objective Various techniques of performing lumbar discectomy are prevalent, each having its rationale and claimed benefits. The authors ventured to assess the total complication rate of lumbar discectomy as well as the complication rates of individual complications, namely CSF leaks, superficial wound infections, deep wound infections, recurrence rates, re-operation rates, and wrong level surgery. Methods This was a retrospective study of patients operated using open discectomy (OD), microdiscectomy (MD), microendoscopic discectomy (MED), interlaminar endoscopic lumbar discectomy (IELD), transforaminal endoscopic lumbar discectomy (TELD), and Destandau techniques (DT) with a minimum follow-up of 2 years. The inclusion criteria were age>15 years, failed conservative treatment for 4-6 weeks, and the involvement of a single lumbar level. Results There is no statistically significant association between surgical technique and complications. The total complication rate was 12.89% in 946 operated cases. The most common complication was recurrence (5.81%), followed by re-operation (3.69%), CSF leak (1.90%), wrong level surgery (0.63%), superficial infection (0.52%) and deep infection (0.31%). There were minor differences in the incidence of complications between techniques. Conclusion This is the first study to compare the complication rates of all the prevalent discectomy techniques across the globe in 946 patients. Although there were minor differences in incidences of complications between individual techniques, there was no statistical significance. The various rates of individual complications provide a reference value for future studies related to complications following discectomy

SPINE20 recommendations 2021: spine care for people's health and prosperity

PURPOSE: The focus of SPINE20 is to develop evidence-based policy recommendations for the G20 countries to work with governments to reduce the burden of spine disease, and disability. METHODS: On September 17-18, 2021, SPINE20 held its annual meeting in Rome, Italy. Prior to the meeting, the SPINE20 created six proposed recommendations. These recommendations were uploaded to the SPINE20 website 10 days before the meeting and opened to the public for comments. The recommendations were discussed at the meeting allowing the participants to object and provide comments. RESULTS: In total, 27 societies endorsed the following recommendations. SPINE20 calls upon the G20 countries: (1) to expand telehealth for the access to spine care, especially in light of the current situation with COVID-19. (2) To adopt value-based interprofessional spine care as an approach to improve patient outcomes and reduce disability. (3) To facilitate access and invest in the development of a competent rehabilitation workforce to reduce the burden of disability related to spine disorders. (4) To adopt a strategy to promote daily physical activity and exercises among the elderly population to maintain an active and independent life with a healthy spine, particularly after COVID-19 pandemic. (5) To engage in capacity building with emerging countries and underserved communities for the benefit of spine patients. (6) To promote strategies to transfer evidence-based advances into patient benefit through effective implementation processes. CONCLUSIONS: SPINE20's initiatives will make governments and decision makers aware of efforts to reduce needless suffering from disabling spine pain through education that can be instituted across the globe

SPINE20 A global advocacy group promoting evidence-based spine care of value

PURPOSE: The Global Burden of Diseases (GBD) Studies have estimated that low back pain is one of the costliest ailments worldwide. Subsequent to GBD publications, leadership of the four largest global spine societies agreed to form SPINE20. This article introduces the concept of SPINE20, the recommendations, and the future of this global advocacy group linked to G20 annual summits. METHODS: The founders of SPINE20 advocacy group coordinated with G20 Saudi Arabia to conduct the SPINE20 summit in 2020. The summit was intended to promote evidence-based recommendations to use the most reliable information from high-level research. Eight areas of importance to mitigate spine disorders were identified through a voting process of the participating societies. Twelve recommendations were discussed and vetted. RESULTS: The areas of immediate concern were "Aging spine," "Future of spine care," "Spinal cord injuries," "Children and adolescent spine," "Spine-related disability," "Spine Educational Standards," "Patient safety," and "Burden on economy." Twelve recommendations were created and endorsed by 31/33 spine societies and 2 journals globally during a vetted process through the SPINE20.org website and during the virtual inaugural meeting November 10-11, 2020 held from the G20 platform. CONCLUSIONS: This is the first time that international spine societies have joined to support actions to mitigate the burden of spine disorders across the globe. SPINE20 seeks to change awareness and treatment of spine pain by supporting local projects that implement value-based practices with healthcare policies that are culturally sensitive based on scientific evidence

“Satellite pedicle screws” - A novel technique of pedicle screw insertion in obese patients undergoing lumbar fusion

The presence of thick sub-cutaneous fat and bulky paraspinal musculature mandates extensive surgical dissection in obese patients undergoing open Transforaminal lumbar interbody fusion surgery. Securing a ‘converging’ pedicle screw trajectory becomes difficult by the counterforces of the erector spinae muscles and thick sub-cutaneous fat in obese patients, especially at the L5-S1 level. We describe the use of a limited standard posterior midline exposure and a separate, far lateral ‘satellite’ incision to insert pedicle screws in an optimal trajectory in obese patients. Through proper pre-operative planning of the axial and sagittal MRI, the appropriate entry site is determined which is executed intra-operatively to insert pedicle screws freehand. Through a single 1.5 cm incision, both L5-S1 screws were inserted. Fourteen obese patients (mean BMI was 30.5 ± 1.1) received 56 satellite pedicle screws for TLIF at L5-S1 level. The mean age was 48.3 ± 9.7 years. The mean blood loss was 244.8 ± 114 ml and the mean operative time was 126.7 ± 82.8 min. In all patients, the screws were inserted as per pre-operative planning without any difficulties. All wounds healed well without wound complications. There were no screw related complications, and in the antero-posterior and lateral radiographs, there were no screw breaches. Satellite free-hand pedicle screws are safe and easily reproducible. They enable limited dissection of the main surgical wound and well-medialised converging pedicle screws in obese patients

Intra-operative computer navigation guided cervical pedicle screw insertion in thirty-three complex cervical spine deformities

Background: Cervical pedicle screw fixation is challenging due to the small osseous morphometrics and the close proximity of neurovascular elements. Computer navigation has been reported to improve the accuracy of pedicle screw placement. There are very few studies assessing its efficacy in the presence of deformity. Also cervical pedicle screw insertion in children has not been described before. We evaluated the safety and accuracy of Iso-C 3D-navigated pedicle screws in the deformed cervical spine. Materials and Methods: Thirty-three patients including 15 children formed the study group. One hundred and forty-five cervical pedicle screws were inserted using Iso-C 3D-based computer navigation in patients undergoing cervical spine stabilization for craniovertebral junction anomalies, cervico-thoracic deformities and cervical instabilities due to trauma, post-surgery and degenerative disorders. The accuracy and containment of screw placement was assessed from postoperative computerized tomography scans. Results: One hundred and thirty (89.7%) screws were well contained inside the pedicles. Nine (6.1%) Type A and six (4.2%) Type B pedicle breaches were observed. In 136 levels, the screws were inserted in the classical description of pedicle screw application and in nine deformed vertebra, the screws were inserted in a non-classical fashion, taking purchase of the best bone stock. None of them had a critical breach. No patient had any neurovascular complications. Conclusion: Iso-C navigation improves the safety and accuracy of pedicle screw insertion and is not only successful in achieving secure pedicle fixation but also in identifying the best available bone stock for three-column bone fixation in altered anatomy. The advantages conferred by cervical pedicle screws can be extended to the pediatric population also

The perspectives of patients and spine surgeons on the effectiveness and reliability of telemedicine consultations for spine ailments—A glimpse at the Indian scenario

Introduction: In view of the ongoing pandemic, telemedicine has been increasingly adopted worldwide. This study was planned to evaluate the effectiveness of telemedicine for patients with spine ailments, and to assess the satisfaction rates and concerns of spine surgeons and patients regarding telemedicine consultations in the Indian scenario. Materials and Methods: Telemedicine appointments for spine patients were conducted through “Zoom Healthcare” online platform between April and December 2020 in a tertiary-care spine center. Questionnaires (including nine and five questions, respectively) were filled by patients and doctors after their consultations. The questionnaire included questions on overall satisfaction, time consumption, ease of setting-up appointment, ease of communication, influence on decision-making, and patient preference. Results: Overall, 70.1%, 23.6%, and 6.3% of patients replied that they were “very satisfied,” “satisfied,” and dissatisfied,” respectively, with their telemedicine appointments. Among postoperative follow-up patients, 69%, 30.2%, and 0.8% expressed that they were “very satisfied,” “satisfied,” and dissatisfied,” respectively, with telemedicine. At the end of session, 88.5% patients opined that they would still prefer a telemedicine appointment for the completed consultation, and 93.4% were happy to use telemedicine for future visits. In all, 100%, 94.1%, and 75% of patients, who belonged to other countries, other cities, and same city, respectively, were satisfied or very satisfied from telemedicine consultations. The doctor’s responses were “very satisfied” or “satisfied” on 96.5% of occasions overall. The doctors required approximately 24.1 min for conducting a telemedicine appointment. Three major concerns for doctors included difficulty in procuring good-quality magnetic resonance imaging (17%), problems with connectivity (14.6%), and difficulty in eliciting certain physical findings (13.2%). Conclusion: Telemedicine is an effective alternative to in-person visits for the assessment of patients with spine ailments. Patients belonging to more distant geographic locations (as compared with local residents) and those requiring postoperative follow-ups can be significantly benefited by this modality

Spontaneous cord transection due to invasive aspergillus spondylitis in an immunocompetent child

Invasive spinal aspergillosis in an immunocompetent child is rare and often there is a considerable delay in diagnosis. A 13-year-old male child treated medically as tuberculosis of spine elsewhere for 1 year, came with complete paraplegia, dorsolumbar kyphosis and intermittently discharging sinus in the back. The child was taken up for surgical decompression and stabilization. Intraoperatively black granulomatous material was noted inside the canal extending anteriorly towards the vertebral body. There was complete cord transection with severe vertebral destruction and osteoporosis. The pathology and microbiology confirmed aspergillosis and the child was started on antifungal treatment. At further follow up, the infection was found to spread to the lung and caused further vertebral destruction. A change in the antifungal medication controlled further spread but failed to eradicate the infection at 2-year follow-up. In this patient, the delay led to extensive vertebral destruction with spine deformity and spontaneous cord transection. Retrospective review of the clinical and radiological findings suggests that this complication could have been prevented if these findings were carefully interpreted. In this era of transplantation and increase in use of immunosuppressive drugs the authors suggests having fungal infection as a differential diagnosis for infections of the spine

Closing–opening wedge osteotomy for severe, rigid, thoracolumbar post-tubercular kyphosis

Childhood spinal tuberculosis, especially when associated with severe vertebral destruction of more than two vertebral bodies can end up in severe deformity. These children show progressive deformity throughout the period of growth and can develop severe kyphosis of >100°. Such kyphosis is severely disabling with significant risk of neurological deficit and respiratory compromise. Surgical correction of these deformities by both anterior and posterior approaches has been described but each have serious limitations of approach, correctability and safety. We describe here a technique of posterior closing–anterior opening osteotomy, which allowed us to correct a rigid post-tubercular deformity of 118° in a 13-year-old boy with neglected spinal tuberculosis. The patient was a 13-year-old boy, who had contracted spinal tuberculosis at the age of 6 years. Although the disease was cured by anti-tubercular chemotherapy, he continued to deteriorate in deformity and presented to us with severe thoracolumbar kyphosis (118°). He was neurologically intact but was beginning to show shortness of breath on exertion. Patient also had fore shortening of the trunk with impingement of the rib cage on the iliac crest. Radiographs revealed complete destruction of T12, L1 and L2 vertebral bodies with the T11 vertebra fusing with L3 anteriorly. CT scans and MRI revealed severe collapse of the vertebral column and the spinal cord being stretched over the ‘internal gibbus’, which was formed by the remnants of the destroyed vertebrae. A single stage closing–opening osteotomy was done by a midline posterior approach with continuous intraoperative spinal cord monitoring. The procedure involved extensive laminectomy of T11–L2, pedicle screw fixation of three levels above and three levels below the apex, a wedge osteotomy at the apex of the deformity from both sides, anterior column reconstruction by appropriate-sized titanium cage and gradual correction of deformity by closing the posterior column using the cage as a fulcrum. This allowed us to achieve a correction to 38° (68% correction). There was no intraoperative or perioperative adverse event and patient had good functional and radiological outcome at 1-year follow-up. In this Grand Rounds case presentation, we have also discussed the aetiology and evolution of severe post-tubercular kyphosis, which is the most common cause of spinal deformity in the developing world. Early identification of children at risk for severe deformity, the time and ideal methods of prevention of such deformities are discussed. The pros and cons of the available options of surgical correction of established deformity and the merits of our surgical technique are discussed
