Abstract:
Condition of vertebral arteries in experimental modeling of cervical vertebrae dislocations at C3-C6 level was studied on 20 section-blocks of cervical spine. Vertebral arteries were contrasted and cervical block was fixed using external fixation device. Various types of dislocation and subluxation under X-ray control were produced. Thus, it was possible to observe dynamic picture of vertebral arteries deformation in traumatic cervical vertebrae dislocation. To confirm the results of angiography the cut up of frozen section-blocks in sagittal plane and in vertebral arteries projection as well as visual control (photography of vertebrae dislocation steps) were performed. Results of experimental study allowed to detect peculiarities of vertebral arteries deformations in cervical vertebrae dislocation and to determine the correlation between the degree of vertebrae dislocation and severity of extracranial vertebral artery deformation. It enables to predict the degree of hemodynamic disorders in the system of vertebral arteries, to determine the role of vascular factor in cervical spine injury and to use the differentional approach to the choice of treatment tactics using routine roentgenography.

Abstract:
ABSTRAKDislokasi fecet cervical pasca trauma terjadi sekitar 6.7% dari cedera cervical spine. Dislokasi facet adalah bagian dari cedera cervical tipe fleksi atau distraksi. Cedera fleksi distraksi digambarkan sebagai pergeseran ke anterior dari korpus vertebra akibat tarikan atau pergeseran dari elemen posterior disertai dengan dislokasi atau fraktur faset. Sudah diketahui bahwa dislokasi faset akan merobek kompleks ligamen posterior dan kapsul faset dan memerlukan operasi stabilisasi sebagai terapi definitif. Ada banyak metode untuk stabilisasi dislokasi cervical. Kami melaporkan 2 pasien, keduanya didiagnosa dengan bilateral facet joint dislocation dari VC5-6 yang kami lakukan operasi anterior cervical discectomy dan fusion (ACDF) dengan hasil 5 bulan pasca operasi, pasien masih bertahan hidup dengan kondisi neurologis yang sama seperti sebelum operasi saat pasien datang ke rumah sakit. Keuntungan dari ACDF adalah durasi operasi yang pendek, nyeri paska operasi yang ringan sampai sedang, perdarahan yang sedikit, dan memberikan rasa nyaman untuk anestesi karena posisi opeerasi terlentang dengan pernapasan pasien yang abdominal. Kata Kunci: Dislokasi Faset Servikal,Dislokasi Sendi Faset Bilateral, Anterior Cervical Discectomy Fusion ABSTRACTTraumatic cervical facet dislocations represent 6.7% of substantial cervical spine injuries. Facet dislocations are part of a spectrum of cervical spine flexion / distraction - type injuries. Flexion distraction injuries are described as anterior displacement of the vertebral body due to tensile or shear failure of the posterior elements coupled with facet fractures or dislocations. It is agreed that bilateral facet dislocations (DF3) disrupt the posterior ligamentous complex and facet capsule and require operative stabilization as the definitive treatment. There are some methods to stabilized the dislocated cervical. We report 2 patient, both patients diagnosed with bilateral facet joint dislocation of VC5-6 that we perform anterior cervical discectomy and fusion (ACDF) with result 5 months follow up, patient survive with neurologist condition same as patient come to hospital. The benefit of ACDF is short length of surgery, mild to moderate postoperative pain, minimal bleeding, and make easy for anesthesia due to supine position with abdominal respiration. Key Words: Cervical Facet Dislocation, Bilateral Facet Joint Dislocation, Anterior Cervical Discectomy Fusion.

Abstract:
AbstractUnilateral facet dislocation of subaxial cervical spine trauma is characterized by dislocation of inferior facet of superior vertebra over the superior facet of inferior vertebra. The injury is due to high-velocity trauma and associated with instability of spinal column. Such unilateral facet dislocations occurring at multiple adjacent levels for some reason are not reported or studied frequently. We have reported two cases of multiple-level dislocation of unilateral facets managed in our hospital with a review of available literature. The injury occurs as one side of the motion segment translates and rotates around an intact facet on the contralateral side. The major mechanism of injury is distractive flexion injury with axial rotation component. The injury is associated with instability secondary to loss of the discoligamentous complex. In cases with multiple-level dislocations of unilateral cervical facets, there are multiple mechanisms associated with significant neurological injury and most of them succumb at the site of injury. Only three other cases are available in English language literature. The neurological outcome is invariably poor. Multiple-level facet dislocations of subaxial cervical spine are reported sparsely in literature. We suspect that due to high-velocity nature of these injuries, most of them succumb soon after injury and not often reported. This article reports two cases of contiguous-level unilateral facet dislocation of subaxial cervical spine with associated injuries and the outcomes with review of literature.

Abstract:
Study design: Retrospective study. Purpose: To determine Reduction rate of cervical fracture dislocations using preoperative gradual in hospital skull traction. Overview of literature: Cervical spine fracture dislocations are unstable injuries and require surgical intervention and stabilization. The approach may be anterior, posterior or combined. Majority of the surgeons prefer anterior approach after initial close reduction of cervical fracture dislocation. If close reduction preoperatively fails, then posterior direct reduction is needed followed by anterior surgery.In this study we intend to determine the rate of success (reduction) using preoperative gradual traction. Method: This retrospective study was conducted at Spine Unit Hayatabad Medical Complex and Aman hospital Peshawar. All patients with cervical fracture dislocations presented between Jan 2015 & Jan 2019, who underwent cervical traction prior to surgical interventions were included in the study. The demographics, types of dislocation, preoperative traction, duration and neurology of all patients were recorded. The success of reduction using closed in hospital gradual traction was assessed using lateral cervical spine x-rays. Data was assessed using SPSS version 20. Results: A total of 52 patients were included in the study with a mean age of 30.06 years (SD± 8.03). In 35(67.3%) patients the dislocation was bifacetal while in 17(32.7%) it was unifacetal. Successful reduction using gradual in hospital awake traction was achieved in 39(75%) patients while in 13(25%) patients reduction was not achieved. Mean duration of preoperative traction was 3.6 (SD±1.1) days with minimum 2 days and maximum 7 days. Conclusion: Gradual in hospital traction in awake patients is an effective mean of reducing cervical fracture dislocations.

Abstract:
Objective. To study efficiency of primary stable metal constructions and halo-vest for lower cervical spine injuries. Material and Methods. Experience in surgical treatment of 62 patients with various injuries of lower cervical spine has been analyzed and summarized. The patients were grouped according to two main factors causing the injured spine dysfunction: dislocation damages (dislocations, fracture-dislocations), in which compression of neurovascular structures and disturbance of spine support ability are caused by vertebra dislocation; and vertebral body fractures (compression, compression-splintered) in which the compression and disturbance are arising from vertebral body destruction. In the first case a reduction of dislocated vertebra by various methods depending on the duration and rigidity of the injury was performed. In the second case a destroyed vertebral body was resected with subsequent stabilization. Results. The choice of surgical tactics with use of modern metal fixation devices was substantiated for treatment of lower cervical spine injuries. Indications for the application of anterior and posterior stabilizing constructions were determined considering a compression direction of neurovascular structures and a degree of destruction of the spine support columns. An algorithm of surgical treatment was suggested basing on a principle of damage reposition irrespective of injury duration. High efficiency of Halo-traction for treatment of lower cervical spine injuries was proved and its most effective application (combination with various methods of internal fixation) was determined. Conclusion. The application of primary stable metal devices in combination with halo fixation is a method of choice for treatment of lower cervical spine injuries.

Abstract:
BACKGROUND Cervical spine fracture-dislocations in patients with ankylosing spondylitis (AS) are mostly unstable and require surgery. However, osteoporosis, one of the comorbidities for AS, could lead to detrimental prognoses. There are few accurate assessments of bone mineral density in AS patients. AIM To analyze Hounsfield units (HUs) for assessing bone mineral density in AS patients with cervical fracture-dislocation. METHODS The HUs from C2 to C7 of 51 patients obtained from computed tomography (CT) scans and three-dimensional reconstruction of the cervical spine were independently assessed by two trained spinal surgeons and statistically analyzed. Inter-reader reliability and agreement were assessed by interclass correlation coefficient. RESULTS The HUs decreased gradually from C2 to C7. The mean values of the left and right levels were significantly higher than those in the middle. Among the 51 patients, 25 patients (49.02%) may be diagnosed with osteoporosis, and 16 patients (31.37%) may be diagnosed with osteopenia. CONCLUSION The HUs obtained by cervical spine CT are feasible for assessing bone mineral density with excellent agreement in AS patients with cervical fracture-dislocation.

Abstract:
Lower cervical spine injuries often manifest as lower cervical vertebral fractures and dislocations, as well as lower cervical facet joint dislocations. Especially in cases of bilateral facet joint dislocations, it is important to rapidly and effectively relieve spinal cord and nerve root compression to prevent secondary spinal cord injury, while also providing reliable and long-lasting stability to the injured segment after surgery. Combined anterior and posterior approaches have the advantages of both pure anterior or posterior approaches, but the actual situation is complex and variable, making systematic theoretical analysis crucial. This study, with bilateral facet joint dislocation of the C6 segment and cervical spinal cord injury as the research background, established a three-dimensional model of the cervical spine C3-C7 after implementing four types of anterior-posterior combined surgeries. The four surgical approaches consist of four combinations: anterior parallel or inclined screw placement combined with posterior Margel or Anderson method screw insertion. Through finite element method, a systematic comparative analysis of the theoretical effects of the four combined surgeries in treating bilateral facet joint dislocation of the cervical spine was conducted. The conclusion was that the variations in the four combined fixation methods have a certain impact on the biomechanical characteristics of the intervertebral disc nucleus. There is a clear mutual influence relationship among anterior and posterior fixation instruments. Based on the model used in this study, it is recommended to use a torque greater than 2.1 nm to tighten the locking nut of the posterior rod to ensure reliable internal fixation.

Abstract:
1. INTRODUCTION Injuries of the lower cervical spine can be among the most devastating injuries of the musculoskeletal system because of the increased risk of the injury to the spinal cord, and also because they so often occur to the younger members of the population (Jones A.A.M. et al., 2003; Sekhon H.S.L. et al., 2001; Ball P.A., 2001). The cervical spine is the most vulnerable spinal segment (Sekhon H.S.L. et al., 2001). The mechanism of cervical spine trauma is defined by the direction and magnitude of the forces that have been applied externally to the head and neck complex resulting in injury (Allen B.L.Jr., 1982). Common injury vectors include flexion, compression, rotation and extension (Allen B.L.Jr., 1982). The pattern of injury is related not only to the external applied force, but also to the initial position or posture of the head and neck at the time of injury (Allen B.L.Jr., 1982). One pattern of these injuries of the lower cervical spine is a facet dislocations (Allen B.L.Jr., 1982). The facet dislocation of the cervical spine result from a hyperflexion injury of the neck (Allen B.L.Jr., 1982). These injuries are characterized radiographically by anterolisthesis of one cervical vertebrae over the other and include the slide anteriorly of the inferior facet of the upper dislocated vertebra over the superior facet of the vertebra below (Allen B.L.Jr., 1982; Razack N. et al., 2000). The facet dislocations of the lower cervical spine represent from 4% to 50% of... [to full text]

Abstract:
Σκοπός: Η προσέγγιση και η αντιμετώπιση των κακώσεων της Αυχενικής Μοίρας της Σπονδυλικής Στήλης (ΑΜΣΣ) εξακολουθεί και σήμερα να παρουσιάζει διαφορές μεταξύ των διαφόρων κέντρων. Κατά καιρούς μάλιστα έχουν προταθεί πλείστοι τρόποι αντιμετώπισης: από συντηρητική με κρανιακή έλξη μέχρι πολύ επιθετική χειρουργική αντιμετώπιση με συνδυασμένες πρόσθιες και οπίσθιες προσπελάσεις. Στόχος της διατριβής ήταν η παρουσίαση της χειρουργικής εμπειρίας της Ορθοπαιδικής Κλινικής του Πανεπιστημίου Πατρών στην αντιμετώπιση των ασθενών αυτών και η ανάλυση των επιπλοκών των διαφόρων μεθόδων σταθεροποίησης. Έγινε προσπάθεια να απαντηθούν τα ακόλουθα ερωτήματα: 1) Ποια πρέπει να είναι σήμερα η διαγνωστική προσέγγιση των ασθενών με κάκωση στην ΑΜΣΣ; 2) Ποιοι ασθενείς χρειάζονται σταθεροποίηση; 3) Τι είδους σταθεροποίηση και ποιες είναι οι επιπλοκές αυτής; Ακολούθως, ποιος πρέπει να είναι ο σύγχρονος αλγόριθμος προσέγγισης των ασθενών με κακώσεις στην ΑΜΣΣ; 4) Ποιες είναι οι μακροχρόνιες επιπτώσεις της σταθεροποίησης; Μεθοδολογία: Εκατόν-δώδεκα ασθενείς με ασταθείς κακώσεις στην ΑΜΣΣ υποβλήθηκαν στην Κλινική μας σε πρόσθια, οπίσθια σταθεροποίηση ή και στις δύο. Ένας ασθενής θεωρούνταν ότι είχε ασταθή κάκωση της ΑΜΣΣ εάν είχε 5 ή παραπάνω βαθμούς με βάση τα κριτήρια αστάθειας των White & Panjabi. Τουλάχιστον ένας χρόνος παρακολούθησης (follow-up) ήταν αναγκαίος για να ενταχθεί ένας ασθενής στη μελέτη, με αποτέλεσμα να επιλεγούν τελικά 97 ασθενείς. Εβδομηντατέσσερις ασθενείς υποβλήθηκαν σε αριστερή προσθιοπλάγια προσπέλαση [Ομάδα Α]. Σε 65 ασθενείς έγινε πρόσθια αποσυμπίεση και τοποθέτηση φλοιοσπογγώδους λαγονίου αυτομοσχεύματος και σταθεροποίηση με πλάκα και βίδες, είτε με πλάκα της AO/ASIF ή με πλάκα CSLP. Στους υπόλοιπους 9 ασθενείς, η αποκατάσταση της σπονδυλικής στήλης περιελάμβανε τη χρήση κλωβού πλέγματος τιτανίου στο οποίο τοποθετούνταν σπογγώδη αυτομοσχεύματα από την περιοχή της σωματεκτομής. Εικοσιτρείς ασθενείς υποβλήθηκαν σε οπίσθια σταθεροποίηση είτε με πλάκες πλαγίων ογκωμάτων (πλάκες Roy-Camille) (19 ασθενείς), ή με πολυαξονικές βίδες (4 ασθενείς) [Ομάδα Β]. Αποτελέσματα – Συμπεράσματα: 1) Εφόσον η κλινική εικόνα ενός ασθενούς με κάκωση στην ΑΜΣΣ επιβάλλει τη διενέργεια αξονικής τομογραφίας, η διερεύνηση μπορεί να γίνει με ασφάλεια με τη χρήση ενός σύγχρονου πολυτομικού αξονικού τομογράφου (MDCT) και μόνο, παραλείποντας τις απλές ακτινογραφίες. 2) Τα κριτήρια αστάθειας των White και Panjabi υπαγορεύουν μια ασταθή κάκωση στην ΑΜΣΣ, η οποία θα πρέπει να αντιμετωπίζεται κατά προτίμηση με χειρουργικό τρόπο. 3) Η στατιστική ανάλυση των αποτελεσμάτων δεν ανέδειξε στατιστικά σημαντικές διαφορές μεταξύ των 2 ομάδων σταθεροποίησης όσον αφορά τις κλινικά σημαντικές επιπλοκές (p=0.26). Ομοίως, οι κλινικά μη σημαντικές επιπλοκές, καθώς και το ποσοστό επανεγχειρήσεων δε διέφεραν στατιστικά μεταξύ των δύο ομάδων (p=0.245 και p=0.475 αντίστοιχα). Ωστόσο, η πρόσθια σταθεροποίηση παρουσιάζει σημαντικά πλεονεκτήματα, μπορεί να αντιμετωπίσει το σύνολο σχεδόν των κακώσεων της ΑΜΣΣ συμπεριλαμβανομένου των εξαρθρημάτων, και μόνο κατ’ εξαίρεση απαιτείται συμπληρωματική σταθεροποίηση. Επιπλέον, η εξέλιξη της μεθόδου βοήθησε στην εξάλειψη επιπλοκών που παρατηρούνταν με τα παλαιότερης τεχνολογίας υλικά. Ως εκ τούτου, οι τρέχουσες ενδείξεις για οπίσθια σταθεροποίηση είναι τα μη ανατασσόμενα εξαρθρήματα, οι κακώσεις πολλαπλών επιπέδων και οι ασθενείς με τραχειοστομία. 4) Η οστεοποίηση των παρακειμένων διαστημάτων στις κακώσεις της ΑΜΣΣ φαίνεται ότι έχει διαφορετική αιτιολογία από αυτή της αυχενικής σπονδύλωσης, μπορεί να εμφανιστεί πολύ πρώιμα στην μετεγχειρητική περίοδο και, ακόμα και όταν είναι εμφανής ακτινολογικά, σπανίως προκαλεί συμπτώματα.<br>Aim: The diagnostic approach and management of patients with cervical spine injuries differs among various centers. Conservative management with skeletal traction to aggressive surgical treatment with combined anterior and prosterior stabilization are within the possible alternatives. We aimed at presenting the experience from the surgical treatment of these patients gathered in the Department of Orthopaedic Surgery in the University Hospital of Patras. We further analyzed the complications associated with each approach and we tried to answer the following questions: 1) Which is the current diagnostic approach of patients with cervical spine injuries? 2) Which patients should be stabilized? 3) What type the stabilization should be and which are its complications? Moreover, which is the appropriate algorithm in the treatment of these patients? 4) Which are the long-term consequences of the stabilization? Materials & Methods: One hundred and twelve patients with unstable cervical spine injuries underwent anterior, posterior stabilization or both. A patient was considered to have an unstable injury if he had ≥ 5 points in the White and Panjabi checklist. At least one year of follow-up was necessary for a patient to be included in the study, which yielded a total of 97 patients. Seventy-four patients underwent a left-sided anterolateral approach [Group A]. Sixty-five of them had anterior decompression and iliac bone grafting. The remaining 9 patients underwent corpectomy and cervical spine reconstruction with titanium mesh cage, filled with morselized autograft from the corpectomy site. All these patients were instrumented using an anterior cervical plate. Twenty-three patients underwent posterior stabilization, either with lateral mass plates of Roy-Camille (19 patients), or polyaxial screws and rods (4 patients) [Group B], along with concomitant iliac bone autografting. Results – Conclusions: 1) If there is a need for computed tomography (CT) in a patient with cervical spine injury, the diagnostic work-up can be done with safety using only a modern multi-detector CT, obviating the need for plain radiographs. 2) The White and Panjabi criteria imply an unstable injury which should be preferentially stabilized by surgical means. 3) Statistical analysis of the clinically significant complications did not reveal significant difference between the posterior procedures and the anterior ones (p=0.26). Likewise, insignificant complications, as well as reoperation rates did not differ significantly among the two groups (p=0.245 and p=0.475 respectively). However, anterior stabilization for cervical spine injuries presents several advantages, can deal with almost all types of injuries and it only exceptionally requires supplemental stabilization. It should be also stressed that the advances in technology and metallurgy have eliminated the complications observed with older implants. Current indications for posterior stabilization are the irreducible dislocations, multilevel injuries and patients with tracheostomy. 4) Adjacent-level ossification in cervical spine injuries appears to be of different etiology than in cervical spondylosis, it may appear very early in the postoperative period and, even when it is evident radiographically, it very rarely (if ever) produces any symptoms.

Abstract:
The mucopolysaccharidoses (MPS) are a group of seven chronic progressive diseases caused by deficiencies of 11 different lysosomal enzymes required for the catabolism of glycosaminoglycans (GAGs). Hurler syndrome (MPS IH) is an autosomal recessive storage disorder caused by a deficiency of α‎-L-iduronidase. Hunter syndrome (MPS II) is an X-linked recessive disorder of metabolism involving the enzyme iduronate-2-sulfatase. Many of the MPS clinical manifestations have potential anesthetic implications. Significant airway issues are particularly common due to thickening of the soft tissues, enlarged tongue, short immobile neck, and limited mobility of the cervical spine and temporomandibular joints. Spinal deformities, hepatosplenomegaly, airway granulomatous tissue, and recurrent lung infections may inhibit pulmonary function. Odontoid dysplasia and radiographic subluxation of C1 on C2 is common and may cause anterior dislocation of the atlas and spinal cord compression.

Abstract:
Approximately 12,400 new cases of spinal cord injuries (SCI) are reported in the United States every year. It has been estimated that the annual financial burden of SCI in the United States is approximately $7.736 billion. The mechanisms of mechanical damage to the spinal cord can be broadly classified into distraction, dislocation or contusion. Distraction injuries are predominantly caused by rapid acceleration-deceleration of the cervical spine. Vertebral burst fractures commonly result in contusion of the spinal cord and relative dislocation of adjacent vertebrae can inter-segmentally shear the spinal cord resulting in injury. Multiple studies have examined the quasi-static mechanical properties of the spinal cord [1–3]. However, considering that most spinal cord injuries occur during dynamic events with relatively high strain rates (ex: 10/s), alarmingly few studies have investigated the time-dependent mechanical characteristics of the spinal cord.

Abstract:
Unilateral facet injuries are relatively common in the sub-axial cervical spine. Facet fractures, capsular disruptions, and posterior ligament tears can all contribute to this type of injury resulting in a range of instability spanning undisplaced fractures to complete unilateral dislocations [1]. For a particular injury pattern, considerable variability exists in the choice of treatment, and the modality selected is frequently based on surgeon preference [2]. This is due, in part, to a lack of biomechanical studies focused on increasing the understanding of changes in spinal stability that occur following cervical spine injury.

Abstract:
Abstract Unstable cervical spine injuries include flexion-distraction injuries with unilateral or bilateral facet dislocations and burst fracture of the vertebral body. These unstable injuries have been treated in various ways. For instance, various posterior fixation methods have been available, and particularly plating with lateral mass screws was proved to provide a rigid fixation. However, most cervical decompressions need to be performed anteriorly because the majority of compression is caused by either vertebral body retro-pulsion or herniated disc material (anterior structure). Anterior plating technique was recently introduced and employed for the surgical treatment of unstable injuries. Anterior plating is thought to offer an acceptable stability through a single surgical approach, but additional posterior fixation is frequently recommend to achieve a sufficient stability. There is a paucity of data on a direct biomechanical comparison of the stiffness provided by modern anterior, posterior, or combined plate-screw fixation in a human cadaveric cervical spine model. The purpose of this study was to compare the biomechanical characteristics of anterior vs posterior plating constructs and to evaluate the stiffness of a combined anterior-posterior fixation construct in a clinically simulated flexion-distraction injury and burst fracture models of the cervical spine.

Abstract:
Lower neck injuries inferior to C4 level, such as fractures and dislocations, occur in motor vehicle crashes, sports, and military events. The recently developed interaction criterion, termed Nij, has been used in automotive safety standards and is applicable to the upper neck. Such criterion does not exist for the lower neck. This study was designed to conduct an analysis of data of lower neck injury metrics toward the development of a mechanistically appropriate injury criterion. Axial loads were applied to the crown of the head of post mortem human subject (PMHS) head-neck complexes at different loading rates. The generalized force histories at the inferior end of the head-neck complex were recorded using a load cell and were transformed to the cervical-thoracic joint. Peak force and peak moment (flexion or extension) were quantified for each test from corresponding time histories. Initially, a survival analysis approach was used to derive injury probability curves based on peak force and peak moment alone. Both force and moment were considered as primary variables and age a covariate in the survival analysis. Age was found to be a significant (p&lt;0.05) covariate for the compressive force and flexion moment but insignificant for extension moment (p&gt;0.05). A lower neck Nij formulation was done to derive a combined interactive metric. To derive cadaver-based metrics, critical intercepts were obtained from the 90% injury probability point on peak force and peak moment curves. The PMHS-based critical intercepts derived from this study for compressive force, flexion, and extension moment were 4471 N, 218 Nm, and 120 Nm respectively. The lower cervical spine injury criterion, Lower Nij (LNij), was evaluated in two different formulations: peak LNij and mechanistic peak LNij. Peak LNij was obtained from the LNij time history regardless of when it occurred. Mechanistic peak LNij was obtained from the LNij time history only during the time when the resulting injury mechanism occurred. Injury mechanism categorization included compression-flexion, compression-extension, and those best represented by a more pure compression-related classification. Mechanistic peak LNij was identified based on the peak timing of the injury mechanism. Peak LNij and mechanistic peak LNij were found to be significant (p&lt;0.05) predictors of injury with age as a covariate. The 50% injury probability was 1.38 and 1.13 for peak LNij and mechanistic peak LNij, respectively. These results provide preliminary data based on PMHS tests for establishing lower neck injury criteria that may be used in automotive applications, sports and military research to advance safety systems.
