ABSTRACT
Methods@#Data regarding patients, who underwent PFD for ACM-I presenting with SM and scoliosis between January 2009 and December 2018, were retrospectively collected. Only patients with 2-year follow-up were included. Sagittal/coronal deformity and sagittal spinopelvic parameters were examined. Symmetry and extent of tonsillar descent, as well as morphology (configuration/variation) and extent of syrinx were determined. @*Results@#A total of 42 patients (20 females; age: 14.2±5.8 years) were included; 35 patients (83.3%) had atypical curves. Mean preoperative coronal Cobb was 57.7°±20.9°; and 12 (28.6%) had significant coronal imbalance. Tonsillar descent was classified as grade 1, 2, and 3 in 16 (38.1%), 11 (26.2%), and 15 (35.7%) patients; 35 patients (83.3%) had asymmetric tonsillar descent; 17 (40.4%), 3 (7.1%), 16 (38.1%), and 6 (14.4%) had circumscribed, moniliform, dilated, and slender syrinx patterns; and 9 (21.4%), 12 (28.6%), and 21 (50%) of syrinx were right-sided, left-sided, and centric. There was no significant relationship between side of tonsillar dominance (p =0.31), grade of descent (p =0.30), and convexity of deformity. There was significant association between side of syrinx and convexity of scoliosis (p =0.01). PFD was performed in all, and deformity correction was performed in 23 patients. In curves ≤40°, PFD alone could stabilize scoliosis progression (p =0.02). There was significant reduction in syrinx/cord ratio following PFD (p 40°.
ABSTRACT
The coronavirus disease 2019 (COVID-19) pandemic has significantly affected all specialty practices in medicine, including the field of spinal surgery. Spinal surgery is unique in that the procedures include not only fully elective and fully emergent interventions, but also involve a separate group of semi-emergent surgeries, where delayed intervention may lead to permanent neurological deficits. Here, we present an evidence-based review on the impact of the COVID-19 pandemic on spinal surgery and our current knowledge about this issue. We conducted a thorough search of the PubMed, Medline, and Google Scholar databases using the keywords, “COVID-19,” “COVID-19 impact on spine surgery,” “coronavirus impact on spine surgery,” “COVID-19 impact on neurosurgery,” “coronavirus impact on neurosurgery,” “COVID-19 impact on spine surgeons,” and “coronavirus impact on spine surgeons” on May 6, 2020. A total of 8,322 articles were identified in the initial search. Articles that were duplicated, those that did not pertain to COVID-19 or spine surgeries, those with details not pertaining to the current topic of interest, and those published in languages other than English were excluded from our analyses. After complete screening, six articles were included in this review. During the previous few weeks, the COVID pandemic has significantly influenced all major aspects of spine surgery across the world. Outpatient care has been gradually shifted from physical visits to tele-health and online consultations. General recommendations have favored the conservative approach over surgeries, although no patient should be deprived of standard care owing to concerns about COVID. The general principles followed by spine surgeons should include early detection of COVID symptomatology; triaging of patients based on underlying spinal pathology; prescription of appropriate investigations to confirm the COVID status; isolation, as needed; selection of optimal management method as per the guidelines; adherence to best intraoperative practices; and ensuring protective measures for non-infected patients, family members, fellow heath care providers, and themselves against the disease.
ABSTRACT
STUDY DESIGN: Prospective cohort study. PURPOSE: The study was aimed at evaluating clinicoradiological factors affecting recovery of neurological deficits in cases of lumbar disc herniation (LDH) treated by lumbar microdiscectomy. OVERVIEW OF LITERATURE: The majority of the available literature on neurological recovery following neurodeficit is limited to retrospective series. The literature is currently limited regarding variables that can help predict the recovery of neurodeficits following LDH. METHODS: A prospective analysis was performed on 70 consecutive patients who underwent lumbar microdiscectomy (L1–2 to L5–S1) owing to neurological deficits due to LDH. Patients with motor power ≤3/5 in L2–S1 myotomes were considered for analysis. Follow-up was performed at 2, 6, and 12 months to note recovery of motor deficits. Clinicoradiological parameters were compared between the recovered and nonrecovered groups. RESULTS: A total of 65 patients were available at the final follow-up: 41 (63%) had completely recovered by 2 months; four showed delayed recovery at the 6-month follow-up; and 20 (30.7%) showed no recovery at 1 year. Clinicoradiological factors, including diabetes, complete initial deficit, areflexia, multilevel disc prolapse, longer duration since initial symptoms, and ≥2 previous symptomatic episodes were associated with a significant risk of poorer recovery (p 0.05 for all). Diabetes mellitus (p=0.033) and complete initial motor deficit (p=0.028) were significantly associated with delayed recovery in the multivariate analysis. CONCLUSIONS: The overall neurological recovery rate in our study was 69%. Diabetes mellitus (p=0.033) and complete initial motor deficit were associated with delayed motor recovery.

STUDY DESIGN: Radiological cohort study. PURPOSE: The options of posteriorly stabilizing C7 vertebra include using lateral mass, pedicle or lamina, as bony anchors. The current study is a computed tomography (CT)-based morphometric analysis of C7 vertebra of 100 Indian patients and discusses the feasibility of these different techniques. OVERVIEW OF LITERATURE: C7 is a peculiar vertebra with unique anatomy, which poses challenges for each of these fixation modalities. There are no reports available in the literature, which discuss and compare the feasibility of diverse posterior C7 fixation techniques in Indian population. METHODS: We included 100 consecutive cervical spine CT scans of Indian patients performed between July 2016 and September 2016. We excluded CT scans with any significant congenital anomaly or other pathological lesions of C7 and patients with non-Indian ethnicity. Regarding screw placement, we assessed and studied various dimensions of the C7 lateral mass, pedicles, and laminae in relevant sections. RESULTS: The mean age of our patients was 49.5±16.1 years. We included 56 male and 44 female patients. The mean anteroposterior and mediolateral dimensions of the lateral mass were 11.38±1.76 and 12.91±1.82 mm, respectively. The mean length of the lateral mass screw (Magerl technique) was 12.17±1.9 mm; 92% of patients could accommodate a lateral mass screw at least 10-mm long (unicortical), whereas 48% could accommodate a screw (unicortical) longer than 12 mm. Foramen transversarium was found in 30.5% of lateral masses. The mean outer and inner cortical widths of the pedicles were 6.5±0.71 mm and 3.72±0.61 mm, respectively. Approximately 58% of pedicles could accommodate 3.5-mm screws (based on the inner cortical pedicle width). The outer cortical and inner cortical widths of the laminae were 6.21±1.2 mm and 3.23±0.9 mm, respectively. Subsequently, 37% of the laminae could accommodate 3.5-mm screws. The mean angle of intralaminar screw trajectory was 50.7°±5.1°, and the mean length of the intralaminar screw was 32.6±3.05 mm. In addition, 96.4% and 60.7% of male patients could accommodate lateral mass screws longer than 10 mm and 12 mm, respectively. However, only 86.4% and 31.8% of female patients could accommodate 10- and 12-mm long lateral mass screws, respectively. Furthermore, 75% of male patients and 36% of female patients had pedicles that could accommodate 3.5-mm diameter screws, and 48.2% of male patients had laminae that could accommodate 3.5-mm screws; however, only 22.7% of female patients could accommodate 3.5-mm laminar screws. CONCLUSIONS: Based on our CT-guided morphometric analysis, 92% and 48% of Indian patients could accommodate at least 10- and 12-mm long lateral mass screws, and 58% of pedicles and 37% of laminae could accommodate 3.5-mm screws. Thus, lateral mass screws (between 10- and 12-mm long) seem to be the safest feasible option for C7 fixation. In case of the need for an alternative mode of stabilization (pedicle or intralaminar screw), particularly in female patients, careful preoperative planning with a CT scan is of utmost importance.

STUDY DESIGN: Prospective, cross-sectional, observational study. PURPOSE: Spine traumata are devastating injuries, which may result in serious disabilities and dire consequences. The current study involves a detailed analysis and description of patients, who were operated at a tertiary care, urban level 1 Spine Centre in India. OVERVIEW OF LITERATURE: Various studies in literature have discussed the epidemiology and patterns of these injuries in trauma patients. However, literature describing the demographic profile and distribution of these traumata in the Indian population is scarce. METHODS: The current study was conducted as a prospective trial involving patients, who were treated at our Spine Centre in India between July 2009 to December 2012. We studied 92 patients with thoraco-lumbar spine fracture, who were operated with short or long segment posterior stabilization. Epidemiological details, pre- and post-hospitalisation care received and other injury pattern factors were studied. RESULTS: Fall from height (46 patients, 50%) was the most common mechanism observed in the patients. Sixty-three percent injuries belonged to AO type A fractures, while 16.2% and 19.4% of the patients had suffered from AO types B and C injuries, respectively. CONCLUSIONS: We identified interesting epidemiological data and prevailing inadequacies in Emergency Spine care management in the study patients. These observations could facilitate implementation of the changes required to improve current standards of patient care.

<p><b>OBJECTIVE</b>To define the preoperative and intraoperative variables which may affect the immediate postoperative outcome in surgically managed patients with unstable pelvic fractures.</p><p><b>METHODS</b>This study was performed prospectively from January 2009 to June 2011 on 36 consecutive patients admitted to the trauma ward of Postgraduate Institute of Medical Education and Research, Chandigarh, with unstable pelvic injuries.</p><p><b>RESULTS</b>In the present study of 36 patients, 29 were managed surgically. Surgical duration was 2 hours in patients operated on within 1 week and 3.4 hours in those operated on after 1 week. The blood loss was 550 ml when surgery was done after a week, but when done within a week it was 350 ml. The average blood loss through Pfanenstial approach was 360 ml, through posterior approach was 408 ml and through combined approach was 660 ml which was significantly high.</p><p><b>CONCLUSION</b>Anterior approach to the pelvis would cause significantly more amount of blood loss than posterior approach and external fixation. Surgical approaches do not have any influence on the surgical duration or the infection rate. The blood loss significantly increases when the surgical time is more than 1 h. The infection rate is not influenced by the duration of surgery. Presence or absence of associated injuries to the head, chest or abdomen is the main determinants of patient's survival and it greatly influences the duration of hospital stay.</p>

<p><b>OBJECTIVE</b>To report a case series of six neglected cervical spine dislocations without neurological deficit, which were managed operatively.</p><p><b>METHODS</b>The study was conducted from August 2010 to December 2011 and cases were selected from the out-patient department of Postgraduate Institute of Medical Education and Research, India. The patients were in the age group of 30 to 50 years. All patients were operated via both anterior and posterior approaches.</p><p><b>RESULTS</b>During the immediate postoperative period, five (83.33%) patients had normal neurological status. One (16.67%) patient who had C5-C6 subluxation developed neurological deficit with sensory loss below C6 level and motor power of 2/5 in the lower limb and 3/5 in the upper limb below C6 level.</p><p><b>CONCLUSION</b>There is no role of skull traction in neglected distractive flexion injuries to cervical spine delayed for more than 3 weeks. Posterior followed by anterior approach saves much time. If both approaches are to be done in the same sitting, there is no need for instrumentation posteriorly. But if staged procedure is planed, posterior stabilization is recommended, as there is a risk of deterioration in neurological status.</p>

Late vascular complications involving aorta are rare but devastating adversities following anterior thoracic spine operations are present. The current article describes our experience with one such patient who had an iatrogenic pseudoaneurysm of the thoracic aorta, mimicking infection. The patient was treated successfully following concomitant efforts by multidisciplinary experts with shunting. We wish to highlight upon the significance of recognizing the possible sinister consequences of a dangerously prominent spinal implant and the role of a suspicious surgeon in identifying these menacing complications at the right time.

Three patients who came to the surgical outpatient department of 'Postgraduate Institute of Medical Education and Research', Chandigarh, India with features suggestive of acute abdomen are presented. On thorough evaluation, they had bilateral psoas abscess and on detailed investigations, tuberculosis was found to be the etiological factor. They were treated conservatively with good follow-up results. Psoas abscess may be clinically difficult to diagnose because of its rarity, insidious onset of the disease, and non-specific clinical presentation which can cause diagnostic delays resulting in high morbidity. Early diagnosis and appropriate management remains a challenge for clinicians. All three patients presented here have recovered following detailed investigation and appropriate management. The diagnosis of spinal tuberculosis should be considered in patients with vertebral osteomyelitis, psoas abscess, and appropriate risk factors such as a history of previous exposure in both developed and developing countries, as tuberculosis is re-emerging as an important etiological factor in spinal pathologies
ABSTRACT
A very rare and serious complication of shoulder dislocation is a lesion to the axillary artery in the elderly population, whose vascular structures have become less flexible. Axillary artery injury secondary to anteroinferior shoulder dislocation is much rarer, especially in the young people. Proper recognition and treatment of this entity offers a full recovery to the patient. Present report highlights the possibility of axillary artery injury with anteroinferior shoulder dislocation. A few case reports and small case series of this injury have been reviewed. And recommendations for management have been brought up to date, in line with current thinking.

This paper discussed the injury mechanism and management of a patient who had concomitant ipsilateral hip and knee dislocations and contralateral open leg fracture. A 32-year-old man presented with ipsilateral fracture-dislocations of the left hip (Pipkin's type IV) and knee (Moore II) joints and contralateral open fracture of the leg bones after a car accident. After emergency resuscitative measures, the hip joint was reduced and Pipkin's fracture was fixed using Ganz approach with lag screws; knee joint was reduced closely and tibial plateau fracture was stabilized with lateral buttress plate and a transarticular spanning fixator. The open fracture on the other leg was debrided and fixed with an external fixator. There was no instability in both joints after fixation when he was examined under anesthesia. The fractures united after 3 months and the patient had no residual instability of hip and knee. There was no clinical or radiological evidence of osteonecrosis in the hip joint after 6 months. At one-year follow-up, he had satisfactory functional outcome with almost normal range of motion at both joints. Ipsilateral hip and knee dislocations are rare injuries and more caution is needed for early diagnosis. A timely appropriate intervention can provide good functional outcome to the patient in this situation.

Intra-articular coronal fractures (Hoffas fractures) of distal femur are rare. Although bicondylar involvement in these fractures has been reported in the literature in association with high velocity traumata, the occurrence of these fractures involving extensor mechanism rupture and avulsion of ipsilateral tibial spine is extremely rare. To our acquaintance, such a fracture pattern has not yet been reported in the literature so far. In this article, we report one such case and discuss the importance of early diagnosis and prompt internal fixation in the management of such cases.We believe that these rare combinations of injuries should be treated aggressively by early open reduction and anatomic rigid internal fixation in order to achieve good recovery of function.

<p><b>OBJECTIVE</b>Talar body fractures are rare and have poor treatment outcome. The purpose of this study is to report the long term surgical treatment outcome of closed talar dome fractures.</p><p><b>METHODS</b>Eight closed talar body fractures, treated by open reduction and internal fixation with small fragment cancellous screws and/or Herbert screws in our level I trauma centre were retrospectively analyzed. Preoperative and postoperative radiographs of the foot (antero-posterior, lateral and oblique views) and ankle (antero-posterior, lateral and mortise views) were obtained. The patients were followed up both radiologically and functionally (foot function index, FFI) after 3 weeks, 6 weeks, 3 months, 6 months and then annually.</p><p><b>RESULTS</b>There were five crush fractures and three shear fractures (two sagittal shear and one coronal shear), with average follow-up of 5 years. No early complications were noticed in these patients. Late complications included osteoarthrosis of subtalar/ankle joints in six patients and osteonecrosis of talar body in four patients. On functional assessment, mean FFI after 5 years was 104.63 points and worse outcome was noticed in crush injury and coronal shear fractures. Sagittal shear fractures had a good functional and radiological outcome.</p><p><b>CONCLUSIONS</b>Late complications subsequent to surgically treated talar body fractures are inevitable, even though exact reduction and rigid fixation are achieved, thus patients are supposed to be counseled about the adverse outcome. Although crush and coronal shear fractures have poor outcome, sagittal injuries have good prognosis on long term evaluation.</p>
