Letter to Editor


Henceforth, nowadays demonstrated poor interpreter reliability of imaging interpretation between surgeons of various specialties and radiologists for a variety of pathologic conditions. Particularly in spine surgeons’ practice Discrepancies in radiologic interpretations can lead to diagnostic frustration and difficulty in formulating treatment plans. Moreover, the third-party payee (insurance party) only relies on documented radiology reports rather than surgeons’ independent interpretation of imaging studies (and never reviews the actual images without clinical findings), which can impact insurance authorization for surgery or reimbursement. Ultimately, conflicting Radiological interpretations may negatively impact patient care. The purpose of my letter to the editor and running research design was to evaluate the rate and degree to which radiologists and spine surgeons differ in interpreting magnetic resonance imaging (MRI) studies in the setting of cervical and lumbar spinal stenosis.
Assessment of The MRI:
Magnetic resonance imaging (MRI) is the standard mode of investigation in spine pathology. Stenosis is a disability triggered by a cord or sac compression because of degenerative spine structure changes with its adjacent structure changes. Compression correlates poorly with Quantifiable language and words used for describing compressive pathology in reports aren’t standardized. MRI [1] is the tool for assessing the extent of cord or sac compromise or injury [2] and typical features include cord or sac compression, altered cord or signals or MRI myelogram in the lumbar spine, canal stenosis, and altered spinal balancing. Despite an investigation, no standard MRI characteristics consistently representing disease severity in canal stenosis have been found [4], cord or sac compression is considered a stamp of authority, and its extent correlates poorly with severity. This may be due to the dynamic component of injury mechanics being untraceable by MRI protocol. [5] or Mechanical stress is the cause of biological differences. Asymptomatic individuals can have a significant cord or sac compression [4, 5]. At present, quantitative measurements such as ‘Spinal Cord Occupation Ratio’, “Maximum spinal cord compression “, ‘Transverse Area’, ‘Compression Ratio’, and ‘Maximum Canal Compromise’ have been used regularly with description. Although their opinions and use of such words, to quantify or qualify the compression are just to provide an objective to the measurements of the cord or sac compression. Standardized terminology exists to describe disc pathology which is a good verse by us, for radiologists aren’t! The nomenclature used by radiologists to report cord or sac compromise impact on clinical management gives the surgeon a drive to extend the surgical plan. I think I will plan to do research with aims to 1) identify terminology used for cord or sac compression 2) compare it 3) From asymptomatic cord compression to symptomatic stenotic features are they able to distinguish between them and 4) Rule out either a language or qualifiers influences spine surgeons opinions.
Do Qualitative or Quantitative Features Identify Spinal Compression Levels?
Maximum Canal Compromise (MCC), Maximum Spinal Cord Compression’ (MSCC) [7]; ‘Spinal Cord Occupation Ratio ‘(SCOR) (3), and ‘Compression Ratio’ (CR) this four are measurements used to calculate compression based on MRI records I found. These represent the visible compromise and good clinical significance [3]. Greater cord compromise is indicated by a larger MCC, MSCC or SCOR, or smaller CR. Quantitative vocabulary used to understand spinal cord or sac compression are: ‘Compress’, and ‘Indent’. ‘Abut’, ‘Flatten’, ‘Touch’, ‘Mould’, ‘Compromise’, ‘Contact’, ‘Displace’ ‘Distort’ ‘Encroach’ ……. Qualifier Term Greater, Just, Lesser Degree, Mild, Mild-Moderate, Minimal, Minor ….maximum numbers of MRI shows the canal diameter as a sign of canal stenosis. Which are non-compared to Slandered deviation and which vary from patient to patient according to their age, sex, height, weight from which demographic region they belong, etc…Many variable terms are used in MRI reporting of spinal cord involvement, with the overlap in their quantitative features. For example, the term ‘Compressed’ = greater quantifiable compromise meaning is inconsistent. Neither qualitative nor quantitative measures of cord or sac involvement correlated with clinical symptoms, despite it generating referral to spinal surgeons. Some relationships are present between radiological reporting of spinal MRI; findings of the clinician by examination clinicians which generate the requirement for MRI to diagnose canal stenosis although the stage of disease and severity can not be specified. Qualitative versus quantitative descriptors are debatable for a longer period for various conditions [8-9]. However, terms chosen by radiologist has no clear guideline or individual meaning. Clinical decision-making depends on radiological reports & their finds. Research shows Radiologist and their reports are better judges that the majority of clinicians [10]. All to gather, research shows suggests that radiologists’ choice of language may have unintended effects on patient care. This is consistent with our findings suggesting that language choice may influence non-expert clinicians’ decisions about whether to refer patients with canal stenosis. The degree of radiological compromise correlates poorly with disease severity. Patients with cord or sac compression may not suffer from UMN or LMN disease respectively. [11] and some patients suffer UMN or LMN diseases without visualized compression due to dynamic injury [5]. Henceforth As the ratio of GP (general physician) to spine specialist is very high in India .They are reliable enough to treat basic family diseases but due to this large gap patients has been already undergone an expensive investigation in the form of an MRI and also informed about the report which was made by radiologist .Hence for the very first consultation the spine surgeon force to see the MRI and not to be evaluated as per the standard protocol and go forward accordingly for the patient profile, this also creates misunderstanding between the GP and Spine Specialist in Indian Scenario. Treating any canal stenosis patient is the work of “BHIM” from “MAHABHARATA” rather than “ARJUNA” who sees a tunnel vision rather than a broad spectrum view.
As Matter of fact, MR imaging cannot currently replace the clinical assessment and vice versa but, notably, interpretation of MRI reports by non-expert clinicians may contribute to false reassurances and variable care. To prevent confusion for non-expert clinicians, descriptive terminology could be removed from reporting and replaced by statements of consistency (or non-consistency) with canal stenosis but further investigation is needed to confirm the value of such an approach. There are, of course, limitations to the conclusions with a lack of data from various centers, and patterns of language likely differ across individual centers, different cities, and countries. Nowadays endoscopy spine is the new sunrise in the world of spine surgery which gives different stories and different tale in a different part of the world, some research article shows that patient underwent endoscopy spine surgery goes for a follow-up MRI after a year shows no signs of surgery, I don’t know how things are going to turn in the future.

Conclusion
That disagreements in MRI interpretation between orthopedic spine surgeons and radiologists occur often. The discrepancies were often with some fold, with spine surgeons rating pathology as more severe. why do I hypothesize that? This is due to the spine surgeons also having clinical data, physical examination, and its interpretation and differentials in their mind while interpreting imaging studies. Insurance companies should not only rely on MR imaging and radiologist interpretation but should also be given equal importance to clinicians and clinical findings. I do agree and pushing a thought that doing better research for this problem by doing collaboration of spine surgeon and radiologist, so we can have better reporting of MRI and radiologist can also took in some clinical inputs from surgeons respectively with their expertise.

Abstract


Introduction: Tuberculosis is one of the leading causes of mortality worldwide due to a single infectious agent. Koch’s spine or spinal tuberculosis is one of the most crippling manifestations of extra-pulmonary tuberculosis. Owing to the lack of image-guided biopsy centers and the high prevalence of the disease, most of the patients are diagnosed and treated on clinical grounds. This practice was thought to lead to a delay in the diagnosis of other pathologies and multi-drug-resistant tuberculosis. This study aims to compare the diagnostic yield of fluoroscopy (C-arm) guided transpedicular biopsy done by orthopaedicians v/s CT guided biopsy done by radiologists in cases of Koch’s spine.
Materials and Methods: The study involved 60 consented patients with a clinico-radiological diagnosis of Koch’s spine randomly divided into 2 groups for biopsy 1) CT-guided biopsy to be done by radiologists 2) C-arm guided biopsy to be done by orthopedicians and results were compared.
Results: The use of CT-guided biopsy and C-arm guided biopsy in the diagnosis of Koch’s spine is increasing taking into consideration of increasing MDR TB. We got a positive answer in 70% of cases via CT-guided biopsy and 53.33% via C-arm guided biopsy. Detection of MDR TB on GeneXpert was the commonest diagnostic feature with a comparatively low rate of positive AFB smear and histopathology.
Conclusion: Results of C-arm guided biopsy are similar to CT guided biopsy with the latter being better.
Keywords: Koch’s spine, biopsy, multi-drug resistant tuberculosis

Abstract


Background & Aims: Motor evoked potentials (MEP) have been widely used as intraoperative neuromonitoring in patients undergoing spine surgery to prevent neurological complications. The present study aims to show the significance of 6% desflurane as an effective agent in maintaining anaesthesia at a minimum alveolar concentration (MAC) of 0.8–1.0 in patients undergoing spine surgery with neuromonitoring.
Methods: This retrospective, cohort, single-centre study was conducted between 2016 and 2018. Patients who underwent spinal surgery along with intraoperative neuromonitoring were included. Anaesthesia was given with weight adjusted intravenous propofol (2-3 mg/kg) and maintained with Oxygen and air with inhalation desflurane (6%) with MAC of 0.8-1.0 and Bispectral index of 40-60. The data of MEP signals were collected at baseline, after instrumentation, decompression, and closure. The MEP data were correlated using Spearman correlation test and Wilcoxon rank test with minimum alveolar concentration, mean arterial pressure, temperature and bispectral index at different time intervals. P value <0.05 was considered statistically significant.
Results: A total of 37 patients (26 females and 11 males) were included in the study with the mean of 52.46±12.85 years. There was no statistically significant correlation between the variables at different time intervals. Although, a statistically significant negative correlation was observed between bispectral index and latency after decompression (p=0.006). A significant difference was observed in visual analogue scale and Oswestry disability index before and after procedure (p< 0.001).
Conclusion: Anaesthesia with 6% desflurane in 0.8-1.0 MAC does not alter MEP signals in patients undergoing spinal surgery without any complication and with adequate recovery rate from anaesthesia.

Abstract


Introduction: In resource limited Hospital in rural and urban city where microscopes are not readily available, I hypothesize that if properly used, good magnifying loupes could offer comparable results to the microscope in relieving rediculpathy which is the primary goal of discectomy.
Material and Methods: Prospective cohort study was conducted on 49 single level lumbar disc prolapsed patients with ridiculer leg pain between January 2017 and March 2021. The microscope was used in 15 patients (29.9%) and loupe in 34 cases (70.1%). Pre-operative assessment clinical examination with spine assessment. Surgical indications included failure of at least 6 weeks medical , physio treatment, pain or progressive neurological deficits. Micro lumbar discectomy was done in all patients. Per-and post operative parameters recorded included: length of the incision, operative time, blood loss, the presence of a wound drain, length of hospital stay, leg and back pain before discharge and in follow up visits and complications. visual analogue scale (VAS) used as a tool.
Results: The demographic, clinical characteristic , radiological characteristics and surgical technique were similar and comparable (p>0.05). The mean length of the incision was 2.5 cm for the microscope group and 3 to 3.5 cm for the loupes group (P value =0.0007).There wasn’t any statistically significant difference in both groups as regard the blood loss (p=1), complication rate and length of hospital stay (p=0.21). There wasn’t any statistically significant difference in VAS score for leg pain (p=0.32) and low back pain (p=0.46). Radicular pain recurred in equal proportion in both groups (p=0.17). 13 (86.2%) in the microscope and 32 (92.6%) in the loupe group had a 3 months post-operative VAS of zero (p=0.32).
Conclusion: Operative microscope and loupes are both justifiable alternative device in lumbar micro discectomy since both have similar and comparable outcome. In rural n urban city hospitals with less resources & less access to microscopes and other minimally invasive equipment such as the endoscope, MLD system or tubular with proven safety and effectiveness over macro disectomy , loupes are safe and effective tools for in lumbar discectomy. Operating Microscopes is more surgeon friendly as it’s gives good viewing angle without or less Work-related Musculoskeletal Disorders (WMSD).

Abstract


Competition is rapidly increasing across all specialties in the field of medicine due to increase in the number of doctors as well as developing technological and marketing changes. It is mandatory to develop and sustain the advantage of surgical skill in particular specialty for the long-term to take advantage of the experience and skills. Fierce competition in turn decreases the overall practice if we do not sustain the competitive advantage which we have in the beginning. It is imperative that we develop sustained competitive advantage to sustain and grow our professional journey for the long-term. In this article we have focussed on how to develop a sustained competitive advantage in the field of spine surgery which can be also applied to other surgical or medical specialties like the other business industries.
Keywords: Medical Profession, Fierce competition, Sustained competitive advantage, Grow professional competence.

Abstract


Introduction- Traditionally MIS TLIF is being performed under fluoroscopic guidance, which is technically difficult in few cases, often inaccurate and involves excessive radiation exposure to the surgeon and OR personnel. Navigation promises to be a better tool, however, literature regarding its accuracy is still evolving.
Aims & Objectives- To evaluate the pedicle screw perforation rate in Navigation guided MIS TLIF
Materials and Methods- All consecutive patients undergoing MIS TLIF under 3D Navigation at single institute between January 2019 to January 2021 were included in the study. O-arm and S8 Stealth Navigation was used in all cases. After prone positioning and part preparation, patient tracker was fixed to a bony point nearest to the operative site, and then first CT scan spin was taken. Under Navigation guidance, all four guide wires were placed. Decompression was planned from the side which was more symptomatic. Screws on the opposite side were placed and connected with rod. Decompression was performed, and interbody cage was inserted from the symptomatic side, followed by insertion of remaining two screws under Navigation. A final CT scan spin was taken to determine the accuracy of hardware.
Results- 92 MIS TLIF were performed during the study period under 3D Navigation. 368 screws in 92 patients were analysed for accuracy. The direction and degree of breach was recorded. Four screws were found to breach, two were lateral breach, one superior breach and one medial breach. All breaches were Gr 1 and none of the screws required revision. Overall accuracy was 98.91 percent.
Conclusion- 3D Navigation is a useful tool in guiding placement of pedicle screws with high accuracy. This tool would be particularly indispensable in MISS cases, when tactile feedback is minimal.
Keywords- Surgical Navigation Systems, Computer-Assisted surgery, Minimally Invasive Surgical Procedures, Pedicle Screws.

Abstract


In recent years, minimally invasive spine surgery techniques have grown increasingly popular with both patients and surgeons. MIS have become increasingly feasible, efficient, and popular for the treatment of a variety of spinal pathologies. Minimally invasive scoliosis surgery (MISS) is not a familiar concept among many spine surgeons, but it is a novel technique with demonstration of advantages of MISS over traditional open technique in the final outcomes and will be the future of adolescent idiopathic scoliosis (AIS) surgery.

Keywords: Minimal invasive spine surgery, Minimally invasive scoliosis surgery (MISS), Adolescent idiopathic scoliosis (AIS).

Abstract


Background: Revision spine surgery needing extension of fixation either require complete exposure of previously operated levels for rod exchange or can be managed by linking the new surgical construct (NSC) to primary surgical construct (PSC) with dominos. Presumptive long rod technique (PLRT) provides additional length of rod for domino placement.
Case report: 80-year male on conservative management developed acute cauda equina syndrome retention due to pre-existing multilevel lumbar stenosis and acute big sequestrated disc prolapse at L12. Emergent surgical intervention in form of L1 to L4 pedicle screw fixation with postero-lateral bone grafting and fragmentectomy was done. Peri-operative period was uneventful. He was started on Teriperatide 20mcg daily with progressive mobilization and physiotherapy. At 4 months of follow-up, he developed L1 osteoporotic fracture with proximal junctional kyphosis (PJK). Patient underwent T12-L1 interbody fusion with extension of fixation to T10 which required complete opening up of previous incision as it was an Indian implant set. A domino of larger foot print couldn’t be accommodated in the space available between L1- L2 screws. Owing to severe osteoporosis and degenerative changes at proximal levels, presumptive oversized rods were inserted with extra lengths of the rods left at proximal ends. This technique is labelled PLRT(presumptive long rod technique) at our institute. At 6 months of follow up, patient developed T10 osteoporotic fracture with PJK and patient was planned for extension of fixation upto T4. Since the extra lengths of rods were available at proximal ends, only the planned operative levels were exposed and it was connected to previous construct using the larger footprint domino. Patient improved clinically and was ambulatory. The patient expired at 18 months due to cardio-respiratory arrest unrelated to the spinal events.
Conclusion: Additional rod lengths intentionally left at adjacent levels during primary surgery where there is anticipation of PJK and adjacent segment disease (ASD) can be a boon when there is need for extension of fixation. These extra lengths of rod can be used to place dominos and connect PSC to NSC without the need for exposure of PSC levels for rod exchange, preventing complications especially in setups with economic constraints.

Abstract


Hirayama disease is a rare neurological condition and is characterized by a sporadic juvenile muscular atrophy of distal upper extremity in young males. The disease is more prevalent in Japan and other Asian countries, though a few cases have been reported in Western countries as well. It manifests as a self-limiting, gradually progressive atrophic weakness of forearm and hand. The anterior displacement of posterior dura during neck flexion leading to cervical cord atrophy has been hypothesized. We discuss a case of a 21-year-old male patient with progressive distal upper extremity weakness, diagnosed with Hirayama disease, and literature review for the same.
Keywords: Hirayama Disease, Juvenile muscular atrophy, Monomelic amyotrophy
