Congenital Stenosis of the Spine-A Cross-Sectional Study of 1019 Whole-Spine Computed Tomography Scans to Determine Prevalence and Association Among Multilevel, Tandem, and Triple Region Stenosis

BACKGOUND

Patients with congenital stenosis of the spine (CSS) present with clinical symptoms at an early age and fewer degenerative hypertrophic changes than the more common degenerative cohort. Literature is lacking in the true prevalence of CSS affecting the 3 segments of the spine in isolation, as well as in tandem in the Indian subcontinent.

METHODS

Anteroposterior spinal canal diameter in axial plane computed tomography at the midvertebral level was measured in asymptomatic patients with whole-spine computed tomography. Spinal canal stenosis was defined as a diameter of <12 mm for the cervical region, <12 mm for the thoracic region, and <13 mm for the lumbar region. Single-level and multilevel stenosis, as well as tandem and triple-region stenosis, were evaluated.

RESULTS

The results show the prevalence of CSS as 16.6%, 11.5%, and 20.1% involving the cervical, thoracic, and lumbar spine, respectively. Single-level stenosis affected 90.6%, 94%, and 79.8% of the patients with cervical, thoracic, and lumbar CSS, respectively. Tandem stenosis affected 10.4% of the population (n = 104), with cervicolumbar stenosis being the most prevalent (n = 51, 5%). The presence of CSS in any one segment of the spine was significantly associated with the presence of stenosis at one of the other segments (P < 0.05). Triple-region stenosis was seen in 0.3% (n = 3) patients.

CONCLUSIONS

The prevalence of cervical, thoracic, lumbar and tandem stenosis from our study is established at 16.6%, 11.5%, 20.1%, and 10.4%. Additionally, our study demonstrates the association between stenosis of the different regions of the spine.

An Observational Study of Hearing Loss Among Menopausal Women

Senile deafness and hearing loss in adults over 50 are major public health issues as a result of the population's ageing demographic. Menopausal women tend to develop hearing loss, while no clear link has been found between the two. The purpose of this study was to determine how menopause and diabetes mellitus affects hearing loss. We assessed 158 menopausal women in total. Pure Tone Audiometry and HbA1c levels was measured, along with appropriate clinical history and examination. The association between those levels and hearing was researched by chi-square test. There were 158 study participants. Mean age of the study population was 50.5 (± 2.49) years. Onset and duration of hard of hearing was assessed in 41 patients (25.9%). 33% (N = 53) of the patients had history of Diabetes mellitus, of which 52.8% offered history of the disease for more than or equal to five years. On audiological assessment, 74.1% had no hearing loss (N = 117), 4.4% had unilateral sensorineural hearing loss (N = 7) and 21.5% had bilateral sensorineural hearing loss (N = 34). Statistics show that hearing loss is statistically connected with ageing and poor glycemic management. With chi square values of 9.629 and P value 0.002 found a significant correlation between ageing and hearing loss. Poor glycemic control is significantly associated with hearing loss with a chi-square value of 4.304 and P value 0.038. Poor glycemic control and menopause is found to be strongly associated with sensorineural hearing loss. Further prospective, hormonal studies including larger population is recommended.

Does Prophylactic Pinning Affect the Proximal Femur Morphology in Slipped Capital Femoral Epiphysis?

Background

The role of prophylactic pinning of the contralateral hip in unilateral SCFE is well established in patients with risk factors for developing contralateral slip. The effect of prophylactic pinning on the growth and morphology of the hip is not well documented in the literature. We aimed to study the effect of prophylactic pinning on the residual growth and morphology of the proximal femur.

Materials & Methods

The institutional database was searched for all unilateral SCFE cases for the period 2011 to 2020. A total of 171 unilateral SCFE cases were identified. All the radiographs were scanned and those patients who had follow-up X-rays till skeletal maturity were included in the study. Prophylactic pinning was performed using 6.5 mm fully threaded cancellous screws in supine position on a radiolucent table. The following radiological parameters were measured on the post-operative X-rays and at skeletal maturity: (i) neck length (NL), (ii) neck-shaft angle (NSA), (iii) femoral offset (FO), (iv) articulo-trochanteric distance (ATD) and (iv) tip-apex distance (TAD) by two different observers.

Results

The mean age of the cohort was 13.7 years. ATD decreased from the mean value of 25.67 mm in post-operative radiographs to 20.84 mm in final follow-up radiographs. The NL, FO, and TAD were found to be increasing with age with mean final follow-up values of 55.35 mm, 41.41 mm, and 6.19 mm respectively compared to post-operative mean values of 50.95 mm, 37.4 mm, and 4.69 mm. There was no significant change in the neck-shaft angle. The mean post-operative NSA was 132.9° and it was 131.8° at final follow-up radiographs.

Conclusion

Prophylactic pinning in unilateral SCFE does not stop the growth of the proximal femur completely. The ATD decreases in all the patients with prophylactic screw fixation probably due to the discrepancy in growth between the trochanteric apophysis and proximal femoral physis. The clinical effects of this subtle change in the morphology of the proximal femur need further investigation.

Ent Manifestations in Sculptors of South Chennai, India: A Cross Sectional Observational Study

Despite the National Occupational Safety and Legislation Act 2020's implementation, reports of workplace accidents are rising in India. Various ear, nose, and throat conditions have been linked to a wide range of physico-chemical variables. Due to a lack of training, inadequate knowledge, a lack of awareness of occupational health and safety risks, or a lack of accessibility to or use of personal protective equipment (PPE), sculptors are frequently exposed to a variety of physical, compound and unplanned risks, chemical, and accidental hazards. The study aimed to assess the various ear, nose and throat manifestations like noise induced hearing loss, occupational rhinitis and non-infectious pharyngitis among the sculptors working in the southern part of Chennai. This observational study was performed in a total of 110 sculptors. Demographic data like age, education, duration of occupation, use of PPE like face mask, ear plug during work hours, whether sculpting is a family occupation or first generation sculptor. A detailed history and thorough ENT examination was performed with pure tone audiometry (PTA), diagnostic nasal endoscopy (DNE) and videolaryngoscopy (VLS). If any problem is detected they will be treated accordingly. Most of them (70%) were in the age group of 21-40 years but 71% of them are sculptors for more than 15 years which infers introduction to the occupation at an early age. The reason for this could be more than 80% of them possessed the heritage of sculpting as their family occupation. Duration of occupation was significantly associated with chronic rhinitis (P value was 0.002) and NIHL (P value was 0.002) whereas education and use of PPE like face mask or ear plugs were not associated with ENT manifestations. This study focuses on the sculptors' working habits, their ignorance of safety precautions, and an assessment of the numerous ENT ailments. These manifestations showed a strong correlation to exposure time. To prevent the issues from becoming more severe, regular medical monitoring is required for early detection and intervention.

Audiological Profile in Allergic Rhinitis, a Hospital Based Study

A type-I hypersensitivity reaction of the nasal mucosa, allergic rhinitis (AR) is distinguished by nasal obstruction, watery rhinorrhea, sneezing, and throat, mouth, and nose irritation. It is assumed that allergies can affect the inner, middle, or outer ear. Many writers have studied the relationship between allergic rhinitis and otitis media. Most of them concur that bacterial infection and Eustachian tube obstruction are significant risk factors for the development of otitis media with effusion in addition to allergies. One hundred study participants had a full clinical evaluation that included an ENT history and examination. In the ENT OPD, the audiological examination was conducted using Pure Tone Audiometry (PTA) and Impedance Audiometry (IA). At frequencies of 250 and 8000 Hz, respectively, the bone and air conduction thresholds were studied. The commercially available "AT235 INTERACOUSTICS" tympanometer was used for the tympanometry procedure. With pressure variations between + 200 and - 300daPa, tympanometry was carried out employing a 226 Hz probe tone. Mean age of study population was 52.16 and 24% each in age group 51 to 60 and 61 to 70 years respectively. 73 (73%) were male and 27 (27%) were female. 46% of allergic rhinitis study population was found to have normal hearing and 43% had mild conductive hearing loss. Most common type of impedance curve was A type (47%). Patients having acute phase of allergy with symptoms less than 3 months had more ear block and secretory otitis media. Patients with duration more than 3 months had resolved secretory otitis media hence the hearing was normal in 33 cases and 11 had mild conductive hearing loss. This study was concluded that there is correlation between the severity of the hearing loss and duration of allergic rhinitis.

A 2-Year Outcomes and Complications of Various Techniques of Lumbar Discectomy: A Multicentric Prospective Study

STUDY DESIGN

Prospective Study.

OBJECTIVES

There are numerous techniques for performing lumbar discectomy, each with its own rationale and stated benefits. The authors set out to evaluate and compare the perioperative variables, results, and complications of each treatment in a group of patients provided by ten hospitals and operated on by experienced surgeons.

METHODS

This prospective study comprised of 591 patients operated between February-2017 to February-2019. The procedures included open discectomy, microdiscectomy, tubular microdiscectomy, interlaminar endoscopic lumbar discectomy, transforaminal endoscopic lumbar discectomy and Destandau techniques with a follow-up of minimum 2 years. VAS (Visual Analogue Score) for back and leg pain, ODI (Oswestry Disability Index), duration of surgery, hospital stay, length of scar, operative blood loss and peri-operative complications were recorded in each group.

RESULTS

Post-operatively, there was a significant improvement in the VAS score for back pain as well as leg pain, and ODI scores spanning all groups, with no significant distinction amongst them. When compared to open procedures (open discectomy and microdiscectomy), minimally invasive surgeries (tubular discectomy, interlaminar endoscopic lumbar discectomy, transforaminal endoscopic lumbar discectomy, and Destandau techniques) reported shorter operative time, duration of hospital stays, better cosmesis, and lower blood loss. Overall, the complication rate was reported to be 8.62%. Complication rates differed slightly across approaches.

CONCLUSION

Minimally invasive surgeries have citable advantages over open approaches in terms of perioperative variables. However, all approaches are successful and provide comparable pain relief with similar functional outcomes at long term follow up.

Case Series - Pediatric Tracheostomy for Upper Airway Obstruction

Certain congenital craniofacial malformations can cause upper airway obstruction. Due to neurological involvement, these craniofacial deformities with upper airway blockage frequently require tracheostomy. Children who need weeks or months of continuous ventilator assistance require tracheostomies, which improve pulmonary toilet and decrease laryngotracheal lesions such subglottic stenosis and tracheomalacia. In this case report we will be discussing about two patients who underwent Pediatric tracheostomy for Pierre Robin sequence and supraglottic stenosis in our institute. This paper emphasizes on some of the rare causes of pediatric upper airway obstruction - Pierre Robin sequence and supraglottic stenosis. Also the importance of tracheostomy procedure, which is the gold standard for management of upper airway obstruction in patients who are not responding to conservative management is emphasized.

Evaluating the Outcomes of Closed Reduction of Different Types of Nasal Bone Fractures

This study was conducted to evaluate the outcomes of closed reduction of different types of nasal bone fractures depending on time between onset of injury and reduction and comparing the outcomes of early closed reduction (within 6 h) of nasal bone fracture with late closed reduction (after 2 weeks). A hospital based Prospective cohort type of study was conducted among cases of nasal bone fracture attending the outpatient department of Otorhinolaryngology at Chettinad Hospital and Research Institute, Chennai during the months of August 2021 to January 2022. A total of 54 participants were included in the study. Primary outcome was to assess the effectiveness of closed reduction of different types of nasal bone fractures postoperatively. The second objective was to compare the outcomes of early closed reduction (within 6 h) of nasal bone fracture with late closed reduction (after 2 weeks). Using chi square test, the association of factors such as age, sex, mode of injury, external framework deformity, type of fracture and treatment was analyzed with outcome measures such as post op degree of deviation, arch irregularity, malalignment, bony irregularity, bony displacement, olfactory disturbances and result. We analyzed the sample data statistically and measured the outcomes which showed that post operatively after undergoing closed reduction, some degree of deviation was present in 17(31.48./.), arch irregularity present in 12(22.2./.), malalignment in 11(20.37./.), bony irregularity in 24(44.44./.), bony displacement in 19(35.19./.), olfactory disturbances in 2(3.70./.). Comparing the outcome factors between early and late reduction, we found that the outcome was better in early closed reduction when compared with late closed reduction. Among the 54 patients studied, the results of closed reduction were found to be excellent in 27(50./.), Fair in 16(29.63./.), Good in 10(18.52./.) and poor in 1(1.85./.) We could thus conclude from this study that early closed reduction of nasal bone fracture gave better results than a late closed reduction in terms of post operative deformity, arch irregularity, malalignment, bony irregularity, bony displacement and olfactory disturbances.

Caffey's Disease of the Scapula: A Case Report

It is characterized by subperiosteal new bone formation usually involving the diaphysis of long bone as well as the ribs, mandible, scapula, and ribs. It is crucial to diagnose the disease at an earlier stage to avoid superfluous surgery. We report a rare case of infantile cortical hyperostosis of the scapula, its clinical and radiological features.

Improved indirect instantaneous torque control based torque sharing function approach of SRM drives in EVs using hybrid technique

This manuscript proposes an improved indirect instantaneous torque control (IITC) based torque sharing function (TSF) method of switched reluctance motor (SRM) drives in electric vehicles (EVs) using a hybrid system. The proposed hybrid techniques are joint performance of both Reptile Search Algorithm (RSA) and Honey Badger Algorithm (HBA), hence it is named as Enhanced RSA (ERSA) method. Here, an IITC method of SRMs for EVs is utilized. It achieves the requirements of the vehicle, like minimum torque ripple, improved speed range, high effectiveness, and maximal torque per ampere (MTPA). To precisely specify the switched reluctance motor and its magnetic features are measured by the proposed method. The modified Torque sharing function compensates the torque error along with incoming phase, which contains the minimal rate of change of flux linkage. Finally, the ERSA method is implemented to define the best control parameters. Then, the proposed ERSA system is performed on the MATLAB platform and the performance is compared to different existing systems. The MSE for case 1 and case 2 using proposed system attains 0.01093 and 0.01095. The voltage deviation for case 1 and case 2 using proposed system reaches 5 and 5. The power factor for case 1 and case 2 reaches a value of 50 and 40 using the proposed system.

"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.

ISSLS PRIZE in basic science 2023: Lactate in lumbar discs-metabolic waste or energy biofuel? Insights from in vivo MRS and T2r analysis following exercise and nimodipine in healthy volunteers

PURPOSE

To quantitatively assess the dynamic changes of Lactate in lumbar discs under different physiological conditions using MRS and T2r.

METHODS

In step1, MRS and T2r sequences were standardized in 10 volunteers. Step2, analysed effects of high cellular demand. 66 discs of 20 volunteers with no back pain were evaluated pre-exercise (EX-0), immediately after targeted short-time low back exercises (EX-1) and 60 min after (EX-2). In Step 3, to study effects of high glucose and oxygen concentration, 50 lumbar discs in 10 volunteers were analysed before (D0) and after 10 days intake of the calcium channel blocker, nimodipine (D1).

RESULTS

Lactate showed a distinctly different response to exercise in that Grade 1 discs with a significant decrease in EX-1 and a trend for normalization in Ex-2. In contrast, Pfirrmann grade 2 and 3 and discs above 40 years showed a higher lactate relative to proteoglycan in EX-0, an increase in lactate EX-1 and mild dip in Ex-2. Similarly, following nimodipine, grade 1 discs showed an increase in lactate which was absent in grade 2 and 3 discs. In contrast, exercise and Nimodipine had no significant change in T2r values and MRS spectrum of proteoglycan, N-acetyl aspartate, carbohydrate, choline, creatine, and glutathione across age groups and Pfirrmann grades.

CONCLUSION

MRS documented changes in lactate response to cellular demand which suggested a 'Lactate Symbiotic metabolic Pathway'. The differences in lactate response preceded changes in Proteoglycan/hydration and thus could be a dynamic radiological biomarker of early degeneration.

Thoracic Myelopathy in Ossified Ligamentum Flavum: Surgical Management and Long-Term Outcome Following 2 Different Techniques of Surgical Decompression

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

Thoracic ossified ligamentum flavum (TOLF) has been reported to present with varying degrees of neuro-deficit and multiple factors have been purported to affect its outcome. Purpose of study was to analyze factors affecting outcome and impact of ultrasonic osteotome (UO).

METHODS

We retrospectively reviewed patients treated for thoracic myelopathy secondary to OLF between 2010 and 2017. 77 patients with complete clinico-radiological records and 2 years follow-up were included. Initial 45 patients, conventional high-speed burr (HSB-group A) was used for decompression. In others, UO was used in combination with HSB (group B). Myelopathy was graded using modified Japanese orthopaedic association grading pre-operatively and each postoperative visit. At final follow-up, recovery rate was calculated. Radiological details including location, morphology, dural ossification, signal change and spinal ossifications were recorded.

RESULTS

Mean mJOA at presentation and final follow-up were 4.3±1.8 and 7.6±1.9 respectively (p = 0.001). HRR was 49.9±23 at final follow-up. A significant reduction in dural tear (12.5%; 29%) and surgical time (125.8±49.5; 189.4±52.5) were observed in group B (p = 0.00). However, there was no statistically significant difference (p = 0.18) in recovery rates between groups A (44.8±26.1) and B (52.8±24.3). Symptom duration (p = 0.00), severity of myelopathy (p = 0.04) and cord signal changes on MRI (p = 0.02) were important predictors of outcome.

CONCLUSION

Use of UO significantly reduced operative time and dural tears, although resulted in similar recovery rate as compared with HSB. Pre-operative severity of myelopathy, symptom duration and presence of cord signal change were the most significant predictors of outcome.

Altered Lysosomal Function Manipulates Cellular Biosynthetic Capacity By Remodeling Intracellular Cholesterol Distribution

Lysosomes are known to influence cholesterol trafficking into endoplasmic reticulum (ER) membranes. Though intracellular cholesterol levels are known to influence the lipid biosynthetic responses in ER, the specific effects of lysosomal modulation on these outcomes is not known. To demonstrate this, C2C12 cells were treated with chloroquine, a lysosomotropic agent, and its effects on cellular biosynthetic capacity, structural and functional status of ER was determined. In addition to its known effects on autophagy reduction, chloroquine treatment induced accumulation of total cellular lipid and ER-specific cholesterol content. It was also observed that chloroquine caused an increase in smooth-ER content with defects in overall protein turnover. Further, since ER and mitochondria function in close association through ER membrane contact sites, it is likely that lysosomal modulation also brings about associated changes in mitochondria. In this regard, we found that chloroquine reduces mitochondrial membrane potential and mitochondrial dynamics. Collectively, the differential biosynthetic response of rise in lipid content, but not protein content, cannot be accounted by merely considering that chloroquine induced suppression of autophagy causes defects in organelle function. In this defective autophagy scenario, both biosynthetic responses such as lipid and protein synthesis are expected to be reduced rather than only the latter, as observed with chloroquine. These findings suggest that cholesterol trafficking/distribution within cellular organelles could act as an intracellular mediator of differential biosynthetic remodelling in interconnected organelles.

Pediatric spinal injuries- current concepts

Spinal injuries in children contribute to the highest mortality and morbidity among all pediatric injuries. Fortunately, these injuries are a rare clinical entity but pose a difficulty in diagnosis due to challenges in neurological evaluation of a child and varied radiological presentation. Anatomical and biomechanical aspects of developing musculoskeletal system, relative plasticity of the pediatric spine make children vulnerable to spine injuries. Though motor vehicle collisions are common, children also suffer non-accidental trauma, falls and sports injuries. More chances of cervical spine involvement, higher susceptibility of spinal cord to tensile forces and associated multisystem injuries result in devastating consequences in children compared to adults. Injuries like SCIWORA, vertebral apophyseal injuries, birth-related spinal cord injuries are more specific injuries in pediatric age group. A vigilant clinical, neurological and radiological evaluation is mandatory in all children with suspected spinal injuries. Normal radiological features like ossification centers, pseudosubluxation and physiological vertebral wedging should be carefully noted as they could be misinterpreted as injuries. While CT scans help in better understanding of the fracture pattern, Magnetic Resonance Imaging in children is beneficial especially in detecting SCIWORA and other soft tissue injuries. Management principles of these pediatric spinal injuries are similar to adults. Literature evidences support conservative management in injuries like SCIWORA, unless there is an ongoing spinal cord compression. As in adults, the role of high dose methylprednisolone is still controversial in pediatric spinal cord injuries. Stable spinal injuries can be managed conservatively using orthosis or halo. Instrumentation by both anterior and posterior techniques has been described, but it is challenging due to smaller anatomy and poor implant purchase. In addition to pedicle screw instrumentation, wiring techniques are very beneficial especially in younger children.

Perioperative analgesic efficacy and safety of erector spinae plane block in posterior cervical spine surgery-a double blinded, randomized controlled study

BACKGROUND CONTENT

Posterior cervical spine surgery (PCSS) are typically open surgeries and entail significant postoperative pain. Current perioperative pain management in PCSS is reliant on multimodal analgesia. While perioperative epidural anesthetic infusion can be used in lumbar surgeries, this is not an option in the cervical spine. Pre-emptive regional analgesia through erector spinae plane block (ESPB) has shown significant perioperative analgesic benefits in lumbar spine surgeries. There are no such clinical studies in PCSS.

PURPOSE

To assess the safety and efficacy of ultrasound-guided ESPB for perioperative analgesia in PCSS.

STUDY DESIGN

Prospective, randomized controlled, double-blinded study.

PATIENT SAMPLE

Eighty-six patients requiring sub-axial PCSS with or without instrumentation were randomized into two groups, those who underwent ESPB with multimodal analgesia (case) and those with only multimodal analgesia (control).

OUTCOME MEASURES

Demographic and surgical data (blood loss, duration of surgery, perioperative total opioid consumption, muscle relaxants used) were assessed. Postoperatively, the surgical site pain, alertness scale, satisfaction score, time to mobilization and complications were recorded.

METHODS

After anesthesia and prone position, case patients received ultrasound-guided ESPB at the T1 level using 15 ml of 0.25% bupivacaine and 8 mg Dexamethasone bilaterally while the control patients received only standard postoperative multimodal analgesia.

RESULTS

There were 43 patients in each group; the two groups were identical in demographic and surgical profile. The intraoperative opioid consumption (119.53±40.35 vs. 308.6±189.78; p<.001) in mcg), muscle relaxant usage (50.00±0.00 mg vs. 59.53±3.75 mg, p<.001), surgical duration (124.77±26.63/ 156.74±37.01 min; p<.01) and intraoperative blood loss (310.47±130.73 ml vs. 429.77±148.50 ml; p<.05) were significantly less in the ESPB group. In the postoperative period, the control group's pain score was significantly higher (p<.001). The Modified Observer Alertness/Sedation Score (MOASS) score and satisfaction scores also showed significant differences between the case and control groups (p<.001). The mean time required to ambulate (sitting/walking) was statistically less in cases (15.81±6.15/20.72±4.02 h) when compared to controls (16.86±6.18/ 23.05±8.88 h; p<.001).

CONCLUSION

In patients undergoing PCSS, ESPB is a safe and effective technique with better outcomes than standard multimodal analgesia alone, in terms of reduced intraoperative opioid requirements and blood loss, better postoperative analgesia and early mobilization.

Audiological Assessment in Post COVID19 Patients- A Cross-sectional Study

Introduction: Hearing loss following a viral infection is a common entity. In recent studies, hearing loss has been seen among Coronavirus Disease 2019 (COVID-19) infected patients, but its association is yet to be established. Aim: To determine the presence of hearing loss and its type in patients after COVID-19 infection. Materials and Methods: A cross-sectional study was conducted at a tertiary health centre, Department of Otorhinolaryngology at Chettinad Academy of Research and Education, Chettinad Hospital and Research Institute, Chennai, from October 2021 to April 2022. Total of 125 patients, who had a positive history of COVID-19 infection, were reviewed in the Otorhinolaryngology Department, one month after they were tested Real Time-Polymerase Chain Reaction (RT-PCR) positive. After obtaining proper clinical history and examination, Pure Tone Audiometry (PTA) were done. Audiological report was assessed and analysed. Qualitative variables will be expressed in proportions and quantitative variables in Mean±SD/ Median (IQR), Chi- square test was applied. Results: This study included 65 males (52%) and 60 females (48%), and the mean age was 38.44±10.9 years years. Among the 125 patients, 12 (9.6%) were diabetic, 14 (11.2%) were hypertensive, 5 (4%) had dyslipidaemia, 3 (2.4%) were hypothyroid, while remaining 91 patients (72.8%) had no comorbidities. Sensorineural Hearing Loss (SNHL) was found among 45 patients (34 with unilateral and 11 with bilateral involvement). Out of them, 2 (4.5%) (4.5%) were in the age group of 18-30 years, 19 (42.2%) in 31-45 years and 24 (53.3%) between 46-60 years age group. Based on the World Health Organization (WHO) classification of hearing loss, 27 patients had mild sensorineural hearing loss, 12 patients with moderate, and 6 patients with moderately severe sensorineural hearing loss. Conclusion: SNHL were found among patients who had COVID-19 infection, but due to the absence of a pre COVID-19 documented audiogram, it was difficult to conclude whether the hearing loss had occurred due to COVID-19, pre-existing hearing loss, or age-related. Further studies are required for proper understanding and correlation.

C7 distal fixation anchor and its influence on sagittal profile in posterior cervical fusion; a retrospective analysis of 44 cases

Study design

Retrospective.

Purpose

In multilevel posterior cervical fusion, whether to stop distal fixation at C7 or T1, remains a matter of debate. We aimed to assess clinical feasibility of C7 as distal fixation point and sought to compare complication rates and radiological outcome between lateral mass screws and pedicle screws at C7.

Overview of literature

Current literature remains inconclusive regarding need for thoracic extension of instrumentation in multilevel posterior cervical fusion.

Methods

We did a retrospective review of 44 consecutive patients who underwent posterior instrumented cervical decompression and fusion for degenerative cervical myelopathy with C7 as distal fixation point, and a minimum follow-up period of two years. We had two groups of patients based on C7 instrumentation.

Group 1

Lateral mass screw fixation.

Group 2

Pedicle screw fixation.

Primary outcome

Post-operative clinico-radiological evaluation of whole study population Secondary outcome: Comparison of complication rates and radiological outcome between groups 1 and 2.

Results

Mean age was 58.06 ± 14.4 years with average follow-up duration of 35.4 ± 4.5 months. There were 18 patients in Group 1 and 26 patients in Group 2. Mean pre-operative mJOA score was 10.51 and post-operative mJOA score was 15.74 with mean recovery rate (RR) 69.82%, of which 30 patients (70.23%) had good recovery and 14 patients (29.77%) had fair recovery at final follow up. The two groups didn't show any significant difference in complication rates and outcome.

Conclusion

C7 as distal fixation anchor is safe and effective in maintaining cervical sagittal balance following multilevel posterior cervical fusion. C7 lateral mass screws are found to be equally efficacious as pedicle screws in preventing worsening of sagittal profile.

Acyclovir with Steroid and Steroid Alone in the Treatment of Idiopathic Facial Nerve Palsy: A Randomised Double-blinded Clinical Study from a Tertiary Care Centre, Chennai, India

Introdutcion: Idiopathic palsy of facial nerve is an acute disease which causes lower motor neuron palsy characterised by facial asymmetry leads to psychological effects and limits one’s social life. Steroids are very effective in the management of Bell’s palsy. The usage of antiviral is still in debate due to the idiopathic aetiology of Bell’s palsy. Aim: To evaluate the efficacy of acyclovir with steroid and steroid alone in the management of Bell’s palsy with respect to the recovery time. Materials and Methods: The randomised double-blinded study was conducted in the Department of Otorhinolaryngology, Chettinad Hospital and Research Institute, Chennai, Tamil Nadu, India, from September 2021 to February 2022 among 100 patients with idiopathic facial nerve palsy. Patients were divided into two groups, 50 patients in each. One group treated with acyclovir (400 mg oral five times daily) and methylprednisolone (1 mg/kg/ day), and other group treated with steroid alone. Both the groups received physiotherapy in the Department of Physiotherapy and taught about home facial exercises. The patients were on regular follow-up for 6 months to monitor the time of the recovery. HouseBrackmann grading system was used for initial assessment and monitor the recovery of the patient. The improvement of House-Brackmann grade to I or II was considered a satisfactory recovery. The association between two groups were assessed by Chi-square test (χ2 ), repeated measures and paired t-test. The statistical significance was considered when p-value<0.05. Results: Out of 100 patients, 52 patients were male and 48 were female, while the age range was 19-58 years. At 2 months, 43 (86%) patients recovered in the combination group and 41 (82%) in the steroid alone group (p-value=0.0038). At 6 months, 48 (96%) patients recovered in the combination group and 42 (84%) in the steroid alone group (p-value=0.178). The overall recovery rate was higher in the combination group (96%) compared to steroid alone group (84%). Conclusion: The combination of acyclovir with steroids in the treatment of Bell’s palsy has better recovery compared to steroid alone therapy.

Audiological Assessment in Post COVID19 Patients- A Cross-sectional Study

Introduction: Hearing loss following a viral infection is a common entity. In recent studies, hearing loss has been seen among Coronavirus Disease 2019 (COVID-19) infected patients, but its association is yet to be established. Aim: To determine the presence of hearing loss and its type in patients after COVID-19 infection. Materials and Methods: A cross-sectional study was conducted at a tertiary health centre, Department of Otorhinolaryngology at Chettinad Academy of Research and Education, Chettinad Hospital and Research Institute, Chennai, from October 2021 to April 2022. Total of 125 patients, who had a positive history of COVID-19 infection, were reviewed in the Otorhinolaryngology Department, one month after they were tested Real Time-Polymerase Chain Reaction (RT-PCR) positive. After obtaining proper clinical history and examination, Pure Tone Audiometry (PTA) were done. Audiological report was assessed and analysed. Qualitative variables will be expressed in proportions and quantitative variables in Mean±SD/ Median (IQR), Chi- square test was applied. Results: This study included 65 males (52%) and 60 females (48%), and the mean age was 38.44±10.9 years years. Among the 125 patients, 12 (9.6%) were diabetic, 14 (11.2%) were hypertensive, 5 (4%) had dyslipidaemia, 3 (2.4%) were hypothyroid, while remaining 91 patients (72.8%) had no comorbidities. Sensorineural Hearing Loss (SNHL) was found among 45 patients (34 with unilateral and 11 with bilateral involvement). Out of them, 2 (4.5%) (4.5%) were in the age group of 18-30 years, 19 (42.2%) in 31-45 years and 24 (53.3%) between 46-60 years age group. Based on the World Health Organization (WHO) classification of hearing loss, 27 patients had mild sensorineural hearing loss, 12 patients with moderate, and 6 patients with moderately severe sensorineural hearing loss. Conclusion: SNHL were found among patients who had COVID-19 infection, but due to the absence of a pre COVID-19 documented audiogram, it was difficult to conclude whether the hearing loss had occurred due to COVID-19, pre-existing hearing loss, or age-related. Further studies are required for proper understanding and correlation.

Risk factors for thirty-day morbidity and mortality after spinal trauma

BACKGROUND

Traumatic Spinal Injuries (TSI) often follow high velocity injuries and frequently accompanied by polytrauma. While most studies have focussed on outcomes of spinal cord injuries, the incidence and risk factors that predict morbidity and mortality after TSI has not been well-defined.

METHODS

Data of consecutive patients of TSI (n = 2065) treated over a 5-year-period were evaluated for demographics, injury mechanisms, neurological status, associated injuries, timing of surgery and co-morbidities. The thirty-day incidence and risk factors for complications, length of stay and mortality were analysed.

RESULTS

The incidence of spinal trauma was 6.2%. Associated injuries were seen in 49.7% (n = 1028), and 33.5% (n = 692) patients had comorbidities. The 30-day mortality was 0.73% (n = 15). Associated chest injuries (p = 0.0001), cervical spine injury (p = 0.0001), ASIA-A neurology (p < 0.01) and ankylosing spondylitis (p = 0.01) correlated with higher mortality. Peri-operative morbidity was noted in 571 patients (27.7%) and were significantly associated with age > 60 (p = 0.043), ASIA-A neurology (p < 0.05), chest injuries (p = 0.042), cervical and thoracic spine injury (p < 0.0001). The mean length of stay in hospital was 8.87 days. Cervical spine injury (p < 0.0001), delay in surgery > 48 h (p = 0.011), Diabetes mellitus (p = 0.01), Ankylosing spondylitis (p = 0.009), associated injuries of chest, head, pelvis and face (p < 0.05) were independent risk factors for longer hospital stay.

CONCLUSION

Key predictors of mortality after spinal trauma were cervical spine injury, complete neurological deficit, chest injuries and ankylosing spondylitis, while additionally higher age and thoracic injuries contributed to higher morbidity and prolonged hospitalisation. Notably multi-level injuries, higher age, co-morbidities and timing of surgery did not influence the mortality.

The Role of Riluzole in Acute Traumatic Cervical Spinal Cord Injury with Incomplete Neurological Deficit: A Prospective, Randomised Controlled Study

Introduction

Riluzole, a benzothiazole sodium channel blocker is acknowledged as a neuroprotective agent in spinal cord injury (SCI). Most of this evidence is based on pre-clinical studies and its effectiveness in clinical setting is undetermined, heretofore.

Methods

A prospective, randomised-controlled study was conducted between April 2019 and March 2020 at a tertiary-level centre. Patients aged 18-65 years with sub-axial cervical spine injury, who presented within 72 h of injury with incomplete neuro-deficit, were included. They were randomised into groups A (riluzole was administered) and B (no adjuvants). All patients were followed up at 6 weeks/3/6/12 months, and clinical [ASIA motor/sensory scores/grade, SCIM3, and NRS (neuropathic pain)] and radiological evaluation was performed.

Results

Twenty-three and 20 patients were included in groups A and B. Two in group A were females, while others were males (p = 0.49). Mean age in groups A and B was 47.7 ± 14.8 and 51.2 ± 14.1 years (p = 0.44). Five patients died prior to 6th-week follow-up. Among the others, there was significant improvement in all neurological parameters in both groups (post-injury vs 1-year; motor score: p < 0.001, sensory score: p < 0.001, SCIM3: p < 0.001, NRS: p < 0.001). In both groups, initial significant improvement was noticed even at the 6th-week follow-up, which further continued until the end of 1 year. There was no statistically significant difference between groups A and B with respect to these neurological parameters (motor: p = 0.15, sensory: p = 0.39, SCIM3: p = 0.68, NRS: p = 0.06).

Conclusion

Administration of riluzole did not significantly improve neurological outcome/neuropathic pain in our cohort. Nevertheless, both our groups demonstrated an overall improvement in neurological outcome at 1 year, as compared with immediate post-injury status.

Accelerated anterior vertebral growth resulting in kyphosis correction following posterior spinal instrumented fusion

PURPOSE

To discuss the effect of posterior instrumented deformity correction and fusion on the progressive endochondral ossification of anterior vertebral body in a patient with congenital kyphosis secondary to type 1 vertebral anomaly.

METHODS

A 15-year-old male patient presented with a progressively worsening congenital TL kyphosis of 52° magnitude secondary to a posterior hemivertebra. His pre-operative antero-posterior vertebral height ratio (APVHR) and anterior vertebral body defect ratio (AVBDR) on CT were 38% and 49%, respectively. He underwent posterior instrumented deformity correction with multilevel type 1 Schwab osteotomies and fusion.

RESULTS

Over the next 3 years, his serial imaging revealed progressive endochondral ossification and gradual increase in the dimensions of the vertebral body. At the final follow-up, there was a significant restoration of the deficient anterior vertebral body, and the final APVHR and AVBDR were 81% and 90%, respectively.

CONCLUSIONS

Restitution of posterior column integrity through stabilization can mitigate the compressive stresses across anterior column. Over a period of time, forces restraining the growth of anterior vertebral apophysis are alleviated, and the vertebra can potentially re-grow to near-normal dimensions in pediatric population. This phenomenon could be well-demonstrated in our patient during follow-up.

LEVEL OF EVIDENCE I

Diagnostic: individual cross-sectional studies with the consistently applied reference standard and blinding.

Is there a role for controlled repositioning and mini-open primary osteoplasty in the management of unstable slipped capital femoral epiphysis?

The management of unstable slipped capital femoral epiphysis is controversial with variable rates of avascular necrosis (AVN). Treatment options include in-situ stabilization, gentle/positional reduction and screw fixation and modified Dunn's procedure (MDP). We present a technique of controlled repositioning (CRP) of the epiphysis to pre-acute slip stage, screw fixation and primary osteoplasty. Between 2015 and 2020, 38 unstable slips were treated in our institution. Of these, 14 underwent successful CRP and the rest were treated with MDP. All the 14 patients who had CRP and completed 1-year follow-up were included for this study. The head-neck angle (HNA) was measured at presentation and alpha angle, head-neck offset and AVN were assessed during follow-up. The average age was 14 years (9-18) and mean follow-up was 17.7 months (12-43). The average intraoperative flexion internal rotation before osteoplasty was -18.5° (-40° to -5°) which improved to +22.1° (+15° to +30°). The average preoperative HNA was 48.7° (34.1° to 70.7°) which improved to 18.4° (1.8° to 35.7°) post-operatively. At final follow-up, the average alpha angle and head-neck offset were 46.4° (30.9° to 64.6°) and 0.22 (0.09 to 0.96), respectively. The AVN rate in the CRP group was 7.1% compared with 20.8% in the MDP group, which was not significant (P = 0.383). Two patients had screw breakage. CRP, screw fixation and mini-open primary osteoplasty is a feasible treatment option in a subgroup of patients with unstable SCFEs. The limitation with this technique is that the final decision is made intraoperatively, and hence the patient and parents need to be counselled and consented appropriately. Level of evidence: Level IV-Case series.

Forequarter Replantation

Traumatic forequarter amputations are rare injuries in which the arm, clavicle, scapula, and proximal shoulder muscles are avulsed from the body. Historically, forequarter amputation has been treated with hemorrhage control, wound debridement, and soft tissue coverage. To our knowledge, successful forequarter replantation has not been previously reported. We present a rare case of forequarter amputation treated successfully with replantation. At the 4.5-year follow-up after replantation, the patient had antigravity elbow flexion, modest shoulder elevation, modest extrinsic finger function, and crude sensation. We discuss relevant technical considerations that indicate that, despite challenges, forequarter replantation can be achieved with success.

A prospective study comparing three different all-posterior surgical techniques in the management of thoracolumbar spinal tuberculosis

Background

Posterior only surgery has been widely performed in the treatment of thoracic and lumbar spinal tuberculosis. Surgical options include debridement with posterior instrumentation only or combined with anterior reconstruction. The aim of this study is to investigate and compare the clinical, functional and radiological outcomes using a single-stage posterior only surgery in thoracolumbar spinal tuberculosis by three different surgical techniques.

Methods

Patients undergoing posterior only surgery for thoracic and lumbar spinal tuberculosis were followed up prospectively and included. Three different procedures, Group-A: Posterior instrumentation with anterior cage reconstruction (n = 49), Group-B: Posterior instrumentation and anterior autologous bone-grafting (n = 21) and Group-C: Posterior column shortening without anterior-reconstruction (n = 52) were compared for kyphosis correction achieved, kyphosis at final follow-up and degree of correction lost. Neurological assessment was done using ASIA impairment Scale(AIS) grades. Functional assessment was done using Visual analogue score (VAS), Modified McNab criteria and NASS satisfaction score.

Results

A total of 122 patients were included in the study, Group-A (49), Group-B (21) and Group-C (52). Radiological correction of kyphotic deformity in anterior reconstruction, Group-A (20.17 ± 9.25⁰) was higher than 13.97⁰ ± 6.06⁰ and 14.27⁰ ± 6.47⁰ achieved in Groups B and C respectively. There was no significant difference in correction lost amongst the three groups (p-value, 0.76). Surgical duration, blood loss and hospital stay were significantly higher in the anterior reconstruction group (p-value, 0.001). Similarly, no significant difference was noted between the three groups in neurological and functional outcomes at 2 years.

Conclusion

Posterior only approach is eminently satisfactory for treating Thoracolumbar Spinal Tuberculosis (STB). All three groups had similar functional and neurological outcomes. However there was a better correction of deformity in patients with anterior cage reconstruction.

Are Modic changes 'Primary infective endplatitis'?-insights from multimodal imaging of non-specific low back pain patients and development of a radiological 'Endplate infection probability score'

PURPOSE

To probe the pathophysiological basis of Modic change (MC) by multimodal imaging rather than by MRI alone.

METHODS

Nineteen radiological signs found in mild infections and traumatic endplate fractures were identified by MRI and CT, and by elimination, three signs unique to infection and trauma were distilled. By ranking the Z score, radiological 'Endplate Infection Probability Score' (EIPS) was developed. The score's ability to differentiate infection and traumatic endplate changes (EPC) was validated in a fresh set of 15 patients each, with documented infection and trauma. The EIPS, ESR, CRP, and Numeric Pain Rating Scale (NRS) were then compared between 115 patients with and 80 patients without MC.

RESULTS

The EIPS had a confidence of 66.4%, 83% and, 100% for scores of 4, 5 and, 6, respectively, for end plate changes suggesting infection. The mean EIPS was 4.85 ± 1.94 in patients with Modic changes compared to - 0.66 ± 0.49 in patients without Modic changes (p < 0.001). Seventy-eight (67.64%) patients with MC had a score of 6, indicating high infection possibility. There was a difference in the NRS (p < 0.01), ESR (p = 0.05), CRP (p < 0.01), and type of pain (p < 0.01) between patients with and without MC.

CONCLUSION

Multimodal imaging showed many radiological signs not easily seen in MRI alone and thus missed in Modic classification. There were distinct radiological differences between EPCs of trauma and infection which allowed the development of an EIPS. The scores showed that 67.64% of our study patients with Modic changes had EPCs resembling infection rather than trauma suggesting the possibility of an infective aetiology and allowing us to propose an alternate theory of 'Primary Endplatitis'.

Safety and Feasibility of Very Early Bronchoscopy-assisted Percutaneous Dilatational Tracheostomy in Anterior Cervical Spine Fixation Patients

Background

Anterior cervical spine fixation (ACSF) is a common mode of stabilization of cervical spine injuries. These patients usually need a prolonged mechanical ventilation, so an early tracheostomy is beneficial for them. However, it is often delayed due to the close proximity to the surgical site, due to the concerns of infection, and increased bleeding. Percutaneous dilatational tracheostomy (PDT) is also considered a relative contraindication due to the inability to achieve adequate neck extension.

Objectives

The objectives of our study are to assess the:Feasibility of performing a very early percutaneous dilatational tracheostomy in cervical spine injury patients, post-anterior cervical spine fixation.Safety in doing so with regard to surgical-site infection, early, and late complications.Benefits with regard to outcome measures like ventilator days and length of stay (LOS) in the intensive care unit (ICU) and hospital.

Materials and methods

We performed a retrospective review of all patients who underwent anterior cervical spine fixation and bedside percutaneous dilatational tracheostomy in our ICU from 1st January 2015 to 31st March 2021.

Results

Out of the 269 patients admitted to our ICU with cervical spine pathology, 84 were included in the study. About 40.4% patients had injury above C5 level (n-34) and 59.5% had below C5 level. About 86.9% patients had ASIA-A neurology. In our study, percutaneous tracheostomy was done at an average of 2.8 days from the cervical spine fixation. Average length of ventilator days post-tracheostomy was 8.32 days, ICU stay was 10.5 days, and hospital stay was 28.6 days. One patient developed anterior surgical-site infection.

Conclusion

We conclude from our study that a very early percutaneous dilatational tracheostomy can be done in post-anterior cervical spine fixation patients as early as within 3 days without significant complications.

Use of antibiotic-impregnated beads in the treatment of lumbosacral surgical site infection: A retrospective case series

Background

Different adjuvant local-antibiotic techniques are described in management of surgical-site infections (SSIs). Antibiotic-laden polymethyl methacrylate (PMMA) spacers have been used in peri-prosthetic infections. However, their role in treatment of spinal SSIs is not well-recognised.

Methods

After approval from Institutional Review Board, we retrospectively evaluated the data of patients aged≥18 years, who were treated for SSIs of lumbo-sacral region (2010-2019). Among them, those who underwent treatment with the placement of cement beads (temporarily/permanently) were identified. This approach was utilised for post-surgical spondylodiscitis patients with significant, associated infection or abscess involving the paraspinal musculature. Only those with≥2 years' follow-up, were included.Patient demographic details, site of infection, details regarding laboratory/radiological investigations, management-protocol followed, pathogen grown, antibiotics used (their dosage and duration of use), complications encountered and outcome were recorded.

Results

13 patients [4 males, age:57.3 ± 12.4 years] were included. Seven had co-morbidities. One had upper-lumbar involvement, one sacral and others had lower-lumbar (L4/distally) disease. While 7 had recent-onset infection (≤2 months since primary surgery), 6 had chronic infection. In 2, 8, 2, and 1 patients, primary surgery was microdiscectomy, TLIF, PLF, and adult-deformity surgery, respectively.Nine underwent two-staged intervention and 4 underwent single procedure. Eleven had PMMA beads, while 2 underwent calcium sulphate bead insertion. Culture grew E coli in 3, Pseudomonas in 2; and E fecalis, K pneumoniae, MSSA and MRSA in one patient each. In 4 patients, beads were not removed. All patients underwent 2 weeks of parenteral antibiotics, followed by 8-12 weeks of oral medications. There was complete remission in all patients, except one who required additional VAC therapy.

Conclusion

Local antibiotic-laden bead application is an effective adjuvant strategy (along with debridement and systemic antibiotics) for the treatment of spinal SSI, where there is substantial infection involving the paraspinal musculature. It is cost-effective and often necessitates second procedure for bead removal.

Spinal Melorheostosis Associated with Intradural Fibrous Band and Extensive Lipomatosis Causing Thoracic Cord Tethering and Myelomalacia: A Unique Case Highlighting Importance of MRI in Management

Axial melorheostosis is rare with only few cases reported and even fewer with symptoms. While symptoms secondary to neural foramen or spinal canal stenosis caused by hyperostotic bone are common, only three symptomatic cases of spinal melorheostosis with associated intradural lipomatous lesions have been reported to date. In none of them the fibrous component of lipofibromatous lesion was identified preoperatively on magnetic resonance imaging. We report here a case of 18-year-old male who presented with thoracic myelopathy secondary to widespread spinal melorheostosis associated with extensive intradural lipomatosis and fibrous component in thoracic lipoma, causing tethering of thoracic spinal cord and myelomalacia. The patient was treated with T2 to T9 posterior instrumented stabilization followed by T3 to T8 laminectomy along with selective thoracic lipofibromatous tumor debulking. Detection of the fibromatous component in multilevel extensive intradural lipomatosis associated with melorheostosis is helpful in planning selection of the level of surgical excision and decompression.

Controlled repositioning and primary osteoplasty as a treatment option for the management of unstable slipped capital femoral epiphysis

The ideal management of an unstable slipped capital femoral epiphysis (SCFE) is still controversial. The currently available options are in-situ screw fixation with delayed corrective osteotomy, closed reduction and screw fixation and anatomic reduction by modified Dunn's procedure (MDP). We present the results of our technique of controlled re-positioning (CRP) with primary osteoplasty in which the epiphysis is repositioned to the preacute slip stage and a mini-open osteoplasty is done in the same sitting to avoid later femoro-acetabular impingement. We had 27 unstable slips which presented to our institution between 2015 and 2019, of which nine were treated with the above technique, and the rest 18 were treated with MDP. All of them were followed up for a minimum of 1 year. The mean intraoperative flexion-internal rotation before osteoplasty was -21.1° (-5° to -40°), which improved to +22.8° (+15° to +30°). Pre- and post-operative mean head-neck angles were 46.5° and 18.3°, respectively, with a decrease of 28.2°. At the final follow-up, the mean alpha angle was 45.1° and the mean head-neck offset ratio was 0.26. None of the patients had avascular necrosis or chondrolysis. The technique of CRP, screw fixation and primary osteoplasty is a viable treatment option for a subset of patients with unstable SCFEs. But, the decision is made intraoperatively and the parents need to be counselled about the need for an alternative procedure if repositioning is unsuccessful. Level of evidence: level IV - case series.

The phenomenon of vertebral body drift in neurofibromatosis and its implications for surgical safety

OBJECTIVE

To report on the phenomenon of body drift in neurofibromatosis scoliosis and discuss its implication on surgical safety.

MATERIALS AND METHODS

Ten dystrophic neurofibromatosis scoliosis (NF) and ten adolescent idiopathic scoliosis (AIS) were studied by radiographs, CT, and MRI. The curve characteristics and a detailed analysis of the morphology of the apical and three adjacent vertebral segments above and below were done. The coronal alignment and the presence of a drift of the vertebral body in relationship to the lamina were carefully studied in both groups and compared.

RESULTS

The mean cobb angle in the NF group was 77.6°, and 63.7° in the AIS group. All the studied vertebra in the NF group had extensive pedicle changes, which were more severe at the apical and periapical regions. Body drift was noted in 29 vertebral segments, with 9/10 of apical segments showing a significant drift. The body drift was associated with significant pedicle dystrophic changes and was independent of the curve magnitude. In comparison, in AIS, no body drift was noted despite a larger deformity and more severe vertebral rotation.

CONCLUSION

The 'body drift' phenomenon was unique to neurofibromatosis scoliosis and was secondary to severe pedicle morphology changes. This was present even in curves less than 60° and could result in cord injury while instrumenting the concave pedicle. Therefore, a thorough preoperative assessment and planning by a 3D CT are mandatory.

Factors determining loss of reduction in paediatric supracondylar humerus fractures treated by closed reduction and percutaneous pinning

Closed reduction and percutaneous pinning is the preferred surgical intervention for paediatric supracondylar humerus fractures (SCHF). Loss of reduction (LOR) is one of the infrequent complications associated with percutaneous pinning. We aim to analyse the various factors that could lead to LOR. We retrospectively reviewed records of all children with Gartland's type III and IV SCHF who were operated at our institution between 2014 and 2016. A defined set of radiologic indices were measured on postoperative and follow-up radiographs. Correlation between LOR (as defined by Skaggs) and radiologic indices, was calculated. In total 187 children who satisfied the inclusion criteria were included in the study. Major LOR was present in 8 patients (4.28%), mild LOR was seen in 21 patients (11.22%), and there was no LOR in 158 patients (84.49%). A pin-spread fracture width ratio of 0.37 had maximum sensitivity and specificity for predicting LOR. The convergent pin configuration had the highest rate of LOR of 15%, whereas it was about 3% in the crossed pin and lateral divergent pinning group. The incidence of iatrogenic ulnar nerve injury in our series was 4.76%, and all were in the cross pinning group. Pin-spread fracture width ratio is the most crucial factor determining LOR, and a ratio of less than 0.37 has a significantly higher rate of LOR. As the incidence of LOR is not significantly different between the lateral-only and crossed pin groups, a medial pin should be used judiciously to avert the risk of ulnar nerve injury. Level of evidence: Level IV.

Can Scoliotic Discs Be Controls for Molecular Studies in Intervertebral Disc Research? Insights From Proteomics

STUDY DESIGN

Proteomic analysis of human intervertebral discs.

OBJECTIVES

To compare the characters of scoliotic discs and discs from magnetic resonance imaging (MRI)-normal voluntary organ donors controls used in disc research employing proteomics and establish "true controls" that can be utilized for future intervertebral disc (IVD) research.

METHODS

Eight MRI-normal discs from 8 brain-dead voluntary organ donors (ND) and 8 scoliotic discs (SD) from 3 patients who underwent anterior surgery for adolescent idiopathic scoliosis were subjected to tandem mass spectrometry, and further analysis was performed.

RESULTS

Mass spectrometry identified a total of 235 proteins in ND and 438 proteins in the SD group. Proteins involved in extracellular matrix integrity (Versican, keratins KRT6A, KRT14, KRT5, and KRT 13A1, A-kinase anchor protein 13, coagulation factor XIII A chain, proteoglycan 4) and proteins involved in transcription and DNA repair (Von Willebrand factor A domain-containing 3B, eukaryotic initiation factor 2B, histone H4, leukocyte cell-derived chemotaxin 2) were found to be downregulated in SD. Inflammatory proteins (C3, C1S), and oxidative stress response proteins (peroxiredoxin-2,6, catalase, myeloperoxidase, apolipoprotein E) were found to be upregulated in SD. These changes were reflected at the pathway level also.

CONCLUSION

Findings of our study confirm that scoliotic discs have an abundance of inflammatory, oxidative stress response proteins, which are either absent or downregulated in the ND group indicating that scoliotic discs are not pathologically inert. Furthermore, this study has established MRI-normal discs from voluntary organ donors as the "true" control for molecular studies in IVD research.

Influence of preoperative coronal and sagittal tibiofemoral subluxation in knee osteoarthritis on the outcome of primary total knee arthroplasty

BACKGROUND

The effect of osteoarthritis (OA) with tibiofemoral (TF) subluxation on patients undergoing total knee arthroplasty (TKA) has been less studied, and there have been no studies on sagittal knee subluxation which is a component of a three-dimensional problem. We aim to analyze the influence of preoperative coronal and sagittal knee subluxation with OA on other radiological parameters and the functional outcome in patients undergoing TKA.

METHODS

We retrospectively reviewed the 179-consecutive primary TKA in 151 patients from January 2017 to June 2017. The radiological parameters analyzed were the mechanical tibiofemoral angle (HKA), joint line congruence angle (JLCA) and coronal tibiofemoral (CTF) subluxation in long leg films. In the lateral view, posterior tibial slope, the settlement area of the femur over the tibia and the sagittal tibiofemoral (STF) subluxation were calculated. Preoperative and postoperative knee society and knee society functional scores were documented. Multivariate regression analysis was done to determine the association of preoperative radiological parameters with coronal and sagittal TF subluxation.

RESULTS

The average follow-up was 31 months (2.6 years). 102 knees (57%) had CTF subluxation (< 5 mm) within normal range, and 77 knees (43%) had CTF subluxation. There was a direct correlation between the magnitude of CTF subluxation and poor preoperative functional scores compared with the non-subluxation group (p < 0.05). CTF subluxation was not associated with the magnitude of varus deformity as it is correlated more with mild deformity (odds ratio [OR] 10.07, 95% confidence interval [CI] 3.47-29.25) than with moderate and severe varus deformity. The degree of the joint line convergence angle was positively correlated with the amount of CTF subluxation (p = 0.003). STF subluxation had a significant correlation with the posterior slope (p < 0.001), but not with the magnitude of varus deformity (p = 0.26).

CONCLUSION

Coronal and sagittal tibiofemoral subluxation had a significant association with poor preoperative clinical scores. The degree of CTF subluxation reduces with the increasing magnitude of varus deformity and JLCA. STF subluxation was associated with the posterior tibial slope. Patients who underwent posterior stabilized TKA had excellent clinical outcomes irrespective of preoperative knee subluxation.

Advanced disc degeneration, bi-planar instability and pathways of peri-discal gas suffusion contribute to pathogenesis of intradiscal vacuum phenomenon

PURPOSE

Intradiscal vacuum phenomenon (IDVP), despite being ubiquitous, is poorly understood. The dynamic passage of peri-discal gases into the degenerated disc is a commonly accepted theory. But the reasons behind its selective appearance in some discs are unevaluated.

METHODS

721 patients with chronic low back pain ± radiculopathy, were evaluated with AP and flexion-extension lateral radiographs and MRI. IDVP was classified based on its morphology and location. Radiographic parameters including sagittal translation, sagittal angulation, lateral listhesis, eccentric disc collapse, Pfirrmann's grade, disc height, Modic changes, anterior longitudinal ligament status, and primary spinal disease at the level of IDVP was analyzed.

RESULTS

IDVP was present in 342 patients, and they had a higher mean age (57.2 ± 12.5 years) than controls (p < 0.001). Eccentric disc space narrowing (26.5% vs 1.3%, p < 0.01), coronal listhesis (7.83% vs 1.1%, p < 0.001), sagittal angular motion difference (11.3 ± 4.6°, p < 0.001), higher mean disc degeneration (4.36 ± 0.69, p < 0.001), ALL disruption (30.3% vs 2.2%, p < 0.001) and Modic changes (88.6% vs 17.5%, p < 0.001) were significantly higher in IDVP discs (vs. non-IDVP). Binary logistic regression analysis indicated sagittal angular motion difference was the most predictive factor. IDVP was classified into three types-dense type (47.5%), linear (29.5%), dot type (23%). Dense type matched radiological correlations of IDVP while dot types behaved like non-IDVP discs.

CONCLUSION

Modic disc-endplate contacts, ALL disruption and coronal translation could be pathways for the passage of peri-discal gases into the degenerated disc. In the pathogenesis of IDVP, advanced disc degeneration, the presence of pathways of gas transfer and angular/coronal instability seem to play complementary roles.

Analysis of risk factors and treatment outcome in patients presenting with neglected congenital spinal deformity and neurological deficit

PURPOSE

Congenital spinal deformities (CSD) are uncommon; and usually present during early childhood. Rarely, patients have been reported to present with neglected CSD in association with myelopathy. The current study reports the largest series of patients with neglected CSD and major neuro-deficit; and discusses their long-term outcome.

METHODS

We retrospectively analysed patients with CSD who presented with myelopathy and underwent surgical management between January 2008 and January 2018. Only patients who had complete clinico-radiological records and completed minimum 2-year follow-up were included. Neurology was graded according to American Spinal Injury Association Impairment, Nurick and modified Japanese Orthopaedic Association scores. Radiological details like deformity type, location, magnitude, and underlying anomaly were recorded. A comparative analysis of parameters between pre-operative and final follow-up periods was performed.

RESULTS

Thirty three (age = 21.1 ± 11.9 years) patients with CSD and myelopathy were included. Mean duration since myelopathy was 5.2 ± 6.2 months. Thirty (91%) patients presented with kyphosis or kyphoscoliosis; and 18 had upper thoracic-level lesion (12 and 3 with mid- or low-thoracic and lumbar lesions). 16 (48.5%) and 12 (36.4%) presented with types 1 and 3 anomalies, respectively. Mean pre-operative mJOA and Nurick grades were 8.8 ± 2.4 and 3.4 ± 0.7. Based on ASIA score, 2, 5, 21 and five patients presented with grades A, C, D and E, respectively. All patients underwent surgeries from posterior-only approach. Mean follow-up was 4.7 ± 2.6 years. In kyphoscoliosis group, coronal and sagittal Cobb improved by 23.8° and 25.9°, respectively. Mean deformity improved by 19.6° and 15.6° in scoliosis and kyphosis groups, respectively. Neurological status improved in 5, remained stable in 23 and deteriorated in five patients. Mean mJOA and Nurick grades at final follow-up was 8.3 ± 3.1and 3.4 ± 0.9.

CONCLUSION

Major neurological deficit is a rare complication of neglected CSD. In our series, such a presentation was observed in patients with kyphotic or kyphoscoliotic deformities, type 1 or 3 vertebral anomalies and proximal thoracic vertebral lesions. Surgery can be valuable in these patients, as it not only stabilises deformity, but also provides the best chance of preventing neuro-deterioration.

The analysis of progression of disc degeneration in distal unfused segments and evaluation of long-term functional outcome in adolescent idiopathic scoliosis patients undergoing long-segment instrumented fusion

PURPOSE

To analyse the progression of disc degeneration in distal unfused lumbar segments in post-operative Adolescent Idiopathic Scoliosis (AIS) patients; and to evaluate pre-operative and post-operative radiological parameters associated with progressive disc degeneration.

METHODS

A retrospective study of patients, who underwent surgery for AIS between 2006 and 2013 at a tertiary-care spine hospital, was conducted. Only patients aged between 11 and 18 years, who underwent deformity correction surgery with pedicle screw-only constructs, minimum of 6.5 year follow-up, and complete radiological data, and were included. On plain radiographs, coronal cobb's angle (CCA), apical translation, lower instrumented vertebra tilt (LIV tilt), LIV-Sacral angle, and sagittal spinal and pelvic parameters were measured. Disc degeneration was assessed on Magnetic Resonance Imaging (MRI) using Pfirrmann's grading. Total endplate score (TEPS) and facet degeneration (by Fujiwara's grading) were also measured. Based on the difference in progression of disc degeneration, patients were classified as Pfirrmann's grade static (PGS) and Pfirrmann's grade progressive (PGP) groups. Comparison of all pre- and post-operative parameters was made between PGS and PGP groups, and statistically analyzed. Functional evaluation was performed using SRS-22 score.

RESULTS

A total of 58 patients were finally included. The mean follow-up was 9.1 years. 43 (74.1%) and 15 (25.9%) patients were classified under PGS and PGP groups, respectively. Among the15 patients in PGP group, selected LIV was L4 in 8, L3 in 3, L1 in 3, and L2 in 1. Among them, 11 patients (73.3%) progressed from grade 1 to grade 2. In the remaining 4 (26.6%), Pfirrmann's grade progressed to ≥ 3. The progression of disc degeneration did not correlate with age or sex distribution (p = 0.3), pre-operative and post-operative TEP scores (p = 032), pre-operative disc or facet degeneration (p = 0.52), number of unfused spinal segments (p = 0.56), pre-operative or post-operative coronal (p = 0.42), or sagittal spinal (p = 0.27) or pelvic parameters (p = 0.14). The final functional outcome (SRS-22) was not significantly different between PGS and PGP groups (p = 0.67).

CONCLUSION

74% of AIS patients demonstrated no signs of progressive disc degeneration at an average follow-up of 9.1 years. 26% (15/58) of AIS patients demonstrated progressive disc degeneration, among whom, degeneration progressed by only 1 Pfirrmann's grade in 74% (11/15). In the remaining four patients, disc degeneration progressed to Pfirrmann's grades 3 or greater. There was no correlation between higher grades of disc degeneration and lower instrumented vertebra (LIV) or functional outcomes scores (SRS-22).

Pelvic osteotomies in hip dysplasia: why, when and how?

Acetabular dysplasia is a significant problem in the spectrum of developmental dysplasia of hip. In a younger child, positioning the femoral head into the acetabulum helps in reciprocal remodeling of the acetabulum and correction of dysplasia. In an older child, the remodeling potential is limited and often the acetabular dysplasia needs surgical intervention in the form of a pelvic osteotomy.

Thus, pelvic osteotomy forms an integral part of surgical management of hip dysplasia. The ultimate goal of these osteotomies is to preclude or postpone the development of osteoarthritis and add more years of life to the native hip.

Pelvic osteotomies play a pivotal role in normalizing hip morphology. The choice of pelvic osteotomy depends on the age of a child, the type of dysplasia and the status of the tri-radiate cartilage.

Several types of re-directional and reshaping pelvic osteotomies have been described in the literature to improve the stability and restore the anatomy and biomechanics of the dysplastic hip.

This article attempts to review the current indications for various pelvic osteotomies with a brief description of their techniques along with the outcomes and complications published thus far. Besides, the guidelines to choose the right pelvic osteotomy are also provided.

Reconstruction of Massive Segmental Distal Femoral Metaphyseal Bone Defects After Open Injury: A Study of 20 Patients Managed with Intercalary Gamma-Irradiated Structural Allografts and Autologous Cancellous Grafts

BACKGROUND

Our aim was to examine the outcome of gamma-irradiated intercalary structural allografts combined with autologous cancellous grafts in treating large metaphyseal bone defects of the distal femur following open injuries.

METHODS

We prospectively included 20 consecutive patients with large metaphyseal bone defects of >4 cm located in the region of the distal femur following open injuries treated between 2010 and 2018, with a mean follow-up of 2 years (range, 2 to 10 years). Of these patients,18 were men and 2 were women. The mean age was 39 years (range, 22 to 72 years). The mean length of the bone defects was 10.1 cm (range, 5.5 to 14.5 cm), and all were in the metaphysis of the distal femur. The surgical technique included initial early debridement and external fixation followed by reconstruction of the bone defect using structural allograft combined with autologous cancellous bone graft harvested from the iliac crest and locking plate fixation. Definitive fixation was performed at an average period of 22.5 days (range, 3 to 84 days) after injury. Osseous union, rate of infection, complications, need for secondary procedures, and functional outcome using the Lower Extremity Functional Scale (LEFS) at the final follow-up were assessed.

RESULTS

After excluding 1 patient who was lost to follow-up, 19 patients with complete follow-up were available for analysis. Of those, 13 patients (68%) achieved complete union at both ends of the allograft with host bone without any further intervention. Three patients (16%) developed aseptic nonunion of the proximal end of the allograft requiring 1 additional procedure each to achieve union. Four patients (21%) developed a deep surgical site infection. Of those, 1 elderly patient required above-the-knee amputation following uncontrolled diabetes and infection. A second patient required 2 additional procedures, and a third patient needed 4 additional procedures to achieve union. The fourth patient developed infection after achieving union, and the infection subsided after debridement and implant removal. The mean LEFS score for all 19 patients was 55 (range, 41 to 75).

CONCLUSIONS

Use of allograft was a reasonable single-stage alternative solution for massive distal femoral bone defects, which united without additional surgery in two-thirds of the patients and without limb-length discrepancy.

Bilateral Unstable Severe Valgus Slipped Capital Femoral Epiphysis: A Case Report

CASE

Bilateral valgus slipped capital femoral epiphysis (SCFE) is a rare condition with few cases reported in the literature. However, there are no reports of bilateral unstable valgus SCFE. We report a unique case of bilateral acute-on-chronic unstable valgus SCFE with severe coxa valga in a 9-year-old girl. She was treated with bilateral capital realignment procedure along with subtrochanteric osteotomy and had a good clinical outcome.

CONCLUSION

We hitherto report a rare case of bilateral unstable valgus SCFE which was successfully managed. This report also highlights the importance of the need for additional osteotomies to address the deformity.

Silent Otitis Media Presenting as Subperiosteal Abscess- A Case Report

Otitis media is an inflammation of mucoperiosteal layer of the middle ear cleft which occurs mostly due to eustachian tube dysfunction superadded with an infective etiology. It is said that younger children are more commonly affected due to the anatomical difference of eustachian tube in children from an adult, but adults are affected as well. Usually acute otitis media may settle following a course of antibiotics, however, it can lead to persistence of infection or becoming chronic and may lead to severe intra and extracranial complications. This report is about a 16-year-old male who presented with a painful swelling in right postauricular region for two weeks duration. The right ear had a diffuse swelling of size 6x1x5 cm in the postauricular region, tender on palpation, firm in consistency, and was fluctuant. Otoscopic examination of the right ear showed bulge out and intact tympanic membrane without active discharge and congestion. High Resolution Computed Tomography (HRCT) of temporal bone showed right otomastoiditis with erosion of the lateral cortex of the right mastoid. He underwent right cortical mastoidectomy under general anaesthesia. The patient was on follow-up for six months and no recurrence was noted.

Role of Telemedicine in Otorhinolaryngology during COVID-19 Pandemic in a Tertiary Care Centre of Tamil Nadu: A Prospective Cohort Study

Introduction: Telemedicine is the practice of using telecommunication technology to provide healthcare services to patients in remote areas. Teleconsultation is used in various specialties of medicine, especially during the COVID-19 pandemic situation. But in developing countries like India, it is less practicable in surgical specialties like Otorhinolaryngology. Aim: To determine the eligibility and effectiveness of telemedicine practice in otorhinolaryngology during the COVID-19 pandemic in a tertiary care centre of Chengalpattu district, Tamil Nadu, India. Materials and Methods: A prospective cohort study was conducted at Chettinad Hospital and Research Institute, Tamil Nadu, India from September 2021 to February 2022 which involved 90 patients who requested a consultation for various ear, nose, and throat complaints. Based on history, a provisional diagnosis was made and treated. Feedback forms contained 11 questions were sent during the revisit and analyses were made. Statistical analysis were done using mean, proportion and Chi-square test. Results: This study included 49 (54.4%) male and 41 (45.6%) female patients with a mean age of 40.68 years. Only 23 (25.6%) patients had no problem seeing the doctor clearly and 19 (21.1%) had no trouble hearing the doctor. Only 4 (4.4%) patients accepted teleconsultation and will use teleconsultation services again. Conclusion: This study concluded that teleconsultation practice was not satisfactory for the majority of patients in the field of otorhinolaryngology. The inability to arrive at the definitive diagnosis and subsequent therapeutic procedures by using telemedicine was the limitation.

Modic changes are associated with activation of intense inflammatory and host defense response pathways - molecular insights from proteomic analysis of human intervertebral discs

BACKGROUND CONTEXT

Patients with modic changes (MC) form a distinct clinical subset with reports of higher intensity of pain, poor clinical and surgical outcomes and higher incidence of recurrence. MC also is an independent risk factor for increased post-operative surgical site infection.

PURPOSE

This study aimed to investigate the biological changes at molecular level, in discs with MCs. We also aim to identify biological biomarkers and potential targets for molecular therapy.

STUDY DESIGN

Experimental analysis MATERIALS AND METHODS: Nucleus pulposus (NP) from 24 patients undergoing microdiscectomy for disc herniation [14 discs with MC and 10 without modic changes (NMC)] were procured. The overall expression of proteins, biological processes, protein-protein and metabolite interactions were analysed and compared. Host defense response proteins (HDRPs) and immunological pathways activated in patients with MC were documented and analysed.

RESULTS

Label-free proteomic approach with stringent filters revealed a total of 208 proteins in MC and 193 in NMC groups. 45 proteins were specific to MC; 30 to NMC and 163 common to both. Downregulated proteins in MC belonged to components of extracellular matrix such as collagens (COL- 6A1, 6A2, 6A3, 11A1, 12A1, and 20A1), and proteoglycans (versican (VCAN), and biglycan (BGN)). Inflammatory molecules [plasminogen (PLG), angiogenin (ANG), fibroblast growth factor-binding protein 2 (FGFBP2), tetranectin (CLEC3B), cartilage acidic protein 1(CRTAC1), kininogen (KNG-1), chitinase-3-like protein 2 (CHI3L2), and ferritin (FTL) were expressed only in the MC group. The significantly altered pathways in MC included Fc Fragment of IgG Receptor IIIa (FCGR3A)-mediated phagocytosis, regulation of Toll-like receptors (TLR) by endogenous ligand, neutrophil and platelet degranulation. 50 HDRPs were identified in the study, 14 of which were specific to MC and included acute phase reactants, antimicrobial peptides, complement cascade proteins, inflammatory molecule and stress response proteins. Metabolite-protein interaction analysis revealed a significant interaction between 19 proteins, specifically involving ubiquitin mediating proteasome degradative pathway and an association with the metabolite-glutamic acid in the MC group. Accumulation of glutamic acid in MC discs was confirmed by quantitative amino acid analysis using High-performance liquid chromatography.

CONCLUSION

Our study confirms that MC represents an intense inflammatory status and activation of host defense response and immunological pathways. Downstream effects leading to ubiquitin mediated proteasomal degradation of ECM proteins and the resulting metabolites such as glutamic acid could cause excessive pain and needs further investigation.

CLINICAL SIGNIFICANCE

We have documented the expression of inflammatory molecules, immune mechanisms and host defense response proteins which throw molecular insights into the pathological mechanisms of MC. Further, ubiquitin mediated proteasomal degradation and accumulation of glutamate in discs with MC might serve as targets for molecular therapy.

A Harrowing Experience of Pinna Lacerations

Otological injuries are not rare presentations to the Emergency Department but they may sometimes be harrowing. These injuries can sometimes lead to haematoma and perichondritis which may lead to cosmetic disfigurement. Hence, opportune and prudent intervention is required to prevent the complications. The present study was conducted to examine the wide range of pinna lacerations, various methods of repair to obtain best cosmetic results and outcome, prevention of development of complications. This case series is about 27 patients with pinna laceration and its management in patients who attended the Emergency Department at a tertiary care hospital. All lacerations of pinna due to any cause were included in the study except chemical and thermal burns. Detailed history was recorded. These patients were managed with wound debridement, suturing and were followed-up regularly to monitor the development of complications. Out of 27 patients, 21 patients had a complete wound healing without any complications. Two patients developed wound gapping and underwent resuturing under local anaesthesia. Perichondritis of pinna has occurred in three patients. Timely intervention is very important for healing and prevention of complications. Normal anatomical contour and good cosmetic results is achieved by adequate wound debridement, maximum tissue restoration, meticulous suturing and wide antibiotic coverage.
