Abstract
Background Atlantoaxial rotatory fixation (AARF) is extremely rare in adults, and there is no consensus on the ideal treatment of adult AARF because of its rarity. We presented a case series of three adult AARFs and reviewed the literature on adult AARFs. We suggest treatment guidelines for the injury based on the literature review. Methods We compiled a series of three adult AARFs seen in our hospital. We also utilized the NCBI library to retrieve literature on adult AARF from 2000 to 2021. We included articles on adult AARF, which described the number of days from injury to diagnosis, Fielding classification, occurrence of associated cervical injuries, and details of treatment and the results. Results Thirty adult AARFs reports fulfilled the criteria and 32 patients were analyzed. Eighteen patients had Fielding Type 1 AARF and were diagnosed within 1 month of injury. Among them, 13 cases healed with conservative treatment. Patients with acute AARF of Fielding Type 1 who underwent manual reduction healed successfully. All patients that required more than 1 month from injury to diagnosis underwent surgery. All cases with AARF Fielding Types 2, 3, and 4 failed conservative treatment. Conclusion The case series and literature review suggest that early diagnosis of adult AARF is essential for successful closed reduction, and the Fielding classification may help determine treatment strategy. Furthermore, this study showed that not only traction but also manual reduction may be a useful treatment for early diagnosed AARF Fielding Type 1 without complications. Level of Evidence: III.

Abstract
PURPOSE The aim of this study is to introduce a new technique for the rapid and accurate reduction of traumatic atlantoaxial dislocation (TAAD) and to investigate its radiological and clinical outcomes. METHODS The clinical outcomes of 18 patients who were diagnosed with acute TAAD and underwent rapid transoropharyngeal closed reduction in our hospital were retrospectively analyzed from January 2015 to December 2020. Following general anaesthesia, all patients were immediately treated with oropharyngeal reduction under somatosensory evoked potential monitoring. The Japanese Orthopedic Association score, neck disability index and visual analog scale score for neck pain were used to evaluate clinical efficacy. Atlantodental distance, posterior atlantodental interval, and the clivus-canal angle were used to assess reduction and spinal cord compression. RESULTS The mean follow-up time was 23.3 months, with a range of 13-38 months. No neurovascular injury occurred during the operations. For all patients, the closed reduction method through the oropharynx under general anaesthesia was successful, and the success rate of reduction was 100%. All patients recovered uneventfully with marked improvement in clinical outcomes and imaging parameters (P < 0.01). Two patients developed mild postoperative dysphagia. One patient developed postoperative fever and pulmonary infection. CONCLUSION Rapid trans-oropharyngeal closed reduction can safely, effectively, and rapidly reduce acute TAAD. This method provides a new strategy for treatment of the condition.

Abstract
Traumatic atlantoaxial rotatory subluxation (AARS) is a condition that is extremely rare in adults when compared to the pediatric population. The most common symptoms of this condition are torticollis and post-traumatic neck pain. Our patient is a 41-year-old male who presented to the emergency room within hours of the injury. He came by himself with his relative as a case of road traffic accident. He was the first passenger and had been restrained during the car accident, with no ejection or rollover. He presented with stiffness/pain and reduced range of motion in the neck. Computed tomography (CT) of the cervical spine showed rotatory subluxation of C1 over the C2 with a locked facet. Within 24 hours of the RTA and patient admission, we attempted cervical traction. The reduction was not successful. So, we decided to reduce AARS through a surgical approach. The patient was taken to the operating room for open reduction and fixation using the Harms technique for C1-C2 fusion. The patient recovered from the surgery uneventfully, without any complications, recovered cervical mobility, and improved torticollis. Surgical management through open reduction and internal fixation is recommended for AARD cases in which close reduction fails due to a locked facet.

Abstract
Cervical vertigo is a common complication of atlantoaxial joint dislocation. However, there is no consensus on the effects of different therapies on the recovery of the patients suffering cervical vertigo. The objective of this randomized controlled trial was to investigate the effect of traction therapy on reducing cervical vertigo induced by atlantoaxial joint dislocation. A total of 96 patients were randomized to receive traction therapy or traditional therapy for two weeks. The overall clinical efficacy was measured based on the 30-point cervical vertigo symptom and function evaluation form. The therapeutic effects were also evaluated based on lateral atlantodental space (LADS), vertigo scale, neck and shoulder pain scale, headache scale, daily life and work scale, psychosocial adaptation scale, and quality of life. Compared with the traditional therapy group, the traction group demonstrated markedly higher overall clinical efficacy (P=0.038). Both the traction therapy group and the traditional therapy group showed significant decrease in LADS (P<0.001), but the traction therapy group had a greater reduction of LAD compared with the traditional group (P<0.01). Traction therapy consistently led to significantly greater relief of cervical vertigo symptoms, including dizziness, neck and shoulder pain, headache, inconvenience in daily living and work activities, impaired psychosocial adaptation, while improving quality of life. The efficacy of traction therapy for cervical vertigo surpasses that of traditional therapy, suggesting that traction therapy is potentially more clinically useful in treating these patients.

Abstract
BACKGROUND Atlantoaxial dislocation (AAD) is a rare and potentially life-threatening condition. Various underlying mechanisms of injury are described in the literature. Here, the authors report an unusual nontraumatic injury mechanism of AAD in a 12-year-old patient. OBSERVATIONS A 12-year-old boy presented with intolerable neck pain and numbness in both upper limbs. The patient’s symptoms had started 2 months after the initiation of online classes during the coronavirus disease 2019 pandemic without a history of trauma. He used a computer for personal study and online classes for prolonged hours with no respite. On physical and radiological evaluation, he was diagnosed with AAD. Before surgery, skull traction was applied to reduce the dislocation and posterior C1 lateral mass screw and C2 pedicle screw fixation was performed. An optimal clinical outcome was achieved with no postoperative complications. A preoperative visual analog scale score of 8.0 was reduced to 0 postoperatively. LESSONS A prolonged fixed neck posture is an unusual underlying cause of AAD. Posterior C1 lateral mass and C2 pedicle screw fixation results in an optimal clinical outcome.

Abstract
Abstract
Introduction Atlantoaxial dislocation (AAD) refers to a loss of stability between the atlas and axis vertebra. The conventional transoral approach and the anterior retropharyngeal approach (ARPA) are adequate for the upper cervical vertebral segments. This study was undertaken to evaluate the usefulness of the ARPA to the odontoid in patients of AAD.
Materials and Methods The study was undertaken on 20 patients admitted in Nil Ratan Sircar Medical College and Hospital, Kolkata, India, with functional disability secondary to AAD. These patients underwent surgery through ARPA to odontoid with or without fixation. Patients were analyzed between October 2014 and September 2016.
Results Maximum number of patients belonged to third decade of life. The male to female ratio was 1.5. The mean duration of symptoms was 10.86 months. Weakness of the upper and lower limbs predominated. About 65% patients had axial neck pain. Nine patients (45%) in total had difficulty in either bowel or bladder. Five patients presented with fracture odontoid and pannus formation of the odontoid process, while six had basilar invagination. One patient underwent anterior odontoid screw fixation and the other 19 patients underwent anterior retropharyngeal odontoidectomy with posterior fixation. Two patients expired in the present study. Most of the patients had improvement in Nurick grade during follow-up. Five patients had transient throat pain and dysphagia. Three patients had superficial surgical site infection. One patient had postoperative cerebrospinal fluid leak.
Conclusion The ARPA to odontoid is a feasible approach for decompression and fixation of the odontoid in AAD cases.

Abstract
CASE A 42-year-old woman presented with a severe neck pain and torticollis due to uncertain etiology. Because her radiographs and computed tomography revealed atlantoaxial rotatory fixation (AARF) that is an extremely rare condition in the adult population, a nonsurgical treatment was initially applied. Because 3 weeks of indirect traction failed, closed reduction was performed under general anesthesia at 2 months after onset, and her symptoms markedly improved without any complications and recurrence. CONCLUSION Closed reduction under general anesthesia for nontraumatic AARF in adult patients might be an effective treatment option, even for chronic cases or intractable cases by traction treatment.

Abstract
Abstract
Purpose The atlantoaxial joint represents the most mobile joint complex within the spine, secured by ligaments and capsules. Integrity of the atlantoaxial joint is crucial with respect to the mobility of the head and the upper spine. Atlantoaxial rotatory dislocation is the most common type of injury within this joint in children and is characterized by a typical position of the head (cock robin position). Nevertheless, this type of injury is frequently overlooked. The purpose of the current study was threefold. First, the characteristics of the patients with atlantoaxial dislocation were identified. Next, we checked if the time to treatment did influence the type of treatment. Finally, we checked if the age of the child at the time of treatment influenced the type of treatment.
Methods Forty-four children, who were treated consecutively due to atlantoaxial dislocation at a single spine center between September 1993 and October 2018, are analyzed retrospectively regarding age, sex, symptoms, etiology, time to diagnosis, time to treatment, and outcome.
Results Forty-four children (30 girls, mean age 8.9 years) were included in the study. The cock robin head position was found in all of them, but neurological deficits were not found in any of them. In 21 patients, dislocation was caused by previous infection (Grisel's syndrome), whereas in 19 patients, dislocation was due to minor trauma. In 4 cases, etiology remained unknown. Mean time to sufficient treatment was 178 days. Eighteen patients received closed reduction and immobilization after 57 days at mean. Open reduction followed by temporary fixation was done in 12 patients after a mean time gap of 188 days. Bony atlantoaxial fusion was necessary in 14 children, who were diagnosed after 319 days on average. Invasiveness of treatment was dependent on the time delay between development of dislocation and treatment; a significant difference was found between invasiveness of treatment and time to treatment (Kruskal–Wallis test, p < 0,05). Moreover, older children were treated significantly more often with fusion than younger ones (χ
2, p = 0,002).
Conclusion Young girls are predisposed to incur an atlantoaxial rotatory dislocation, which usually occurs due to minor trauma or infection. The cock robin position is characteristic, but neurological deficits are not common. There is a need for early and sufficient treatment because delayed treatment necessitates more invasive treatment, thus leading to a complete loss of function of the most mobile joint within the spine. Finally, older children are predisposed to more invasive treatment strategies.

Abstract
Atlantoaxial rotatory fixation (AARF) in an adult without any trauma is an extremely rare condition. Here we report a case of surgical treatment for existing atlantoaxial rotatory fixation in an adult with spastic torticollis. A 50-year-old man had become aware of torticollis without any cause of injury 6 weeks before he visited our hospital, where he presented with a one-week history of severe neck pain. Based on the local and imaging findings, we diagnosed him as having existing AARF of Fielding classification type I. The AARF was not reduced by 3 weeks of Glisson traction. Thus, we performed C1-C2 posterior fusion surgery 3 months after his initial visit. Although CT findings just after surgery showed that the C1-2 facet subluxation was reduced, the complaint of torticollis was not improved, with scoliosis at the middle to lower cervical level because of left sternocleidomastoid hypertonia. Administration of diazepam was initiated 2 weeks after surgery and botulinum toxin injections to the left sternocleidomastoid were added 2 months after surgery under the neurological diagnosis of spastic torticollis. As a result, the complaint of his torticollis was significantly improved 3 months after surgery. There were no relapses of the torticollis and complete fusion of the C1-C2 laminae was observed at the 2-year final follow-up. Surgical treatment for AARF in an adult should be considered if the diagnosis of AARF is delayed. In addition, appropriate treatment for spastic torticollis applied after surgery resulted in a favorable outcome of this case.

Abstract
Atlantoaxial rotatory dislocations (AARDs) are common in the pediatric population and rarely seen in adults. We describe a case of neglected AARD and subsequent management. A 25-year-old man developed a Fielding type 1 AARD following a road traffic accident. He was managed conservatively for 1.5 months before being referred to us. The patient underwent surgery 1.5 months after the accident. Closed reduction failed and C1-2 fixation with the Harms technique was performed after intraoperative reduction resulting in correction of deformity. Delay of treatment makes intraoperative reduction more difficult and increases the possibility of the chronic permanent change of neck muscles and ligaments. Hence, a high index of suspicion with a thorough clinical examination and judicious use of radiological investigations is paramount to the appropriate management of such cases.

Abstract
Atlantoaxial rotatory fixation (AARF) is a rare condition in adults and is almost always due to an accompanying trauma. The first example of traumatic AARF in adults was reported by Corner in 1907 and since then only 55 adult cases with this rare traumatic scenario have been published so far. Approximately 80% of adults with traumatic AARF are diagnosed soon after the traumatic events. However, in the remaining casualties, the condition might be missed with some delay from the diagnosis to treatment. If this pathology is diagnosed early enough, the conservative attempts for a closed reduction are usually effective. After closed reduction, external immobilization is required to prevent recurrence of the dislocation. However, with delayed diagnosis, the condition may remain refractory to traction on manipulation and require an open reduction instead. In the literature, such irreducible chronic AARFs are rarely reported, being confined to only 14 adult examples, in whom surgical intervention for correction of the deformity will be required. In such cases, release of the atlantoaxial facet joints is the first surgical step. In the subsequent step, reduction of the dislocated facet joints can be done via one of the already described maneuvers. As the final step, C1-C2 fixation will be necessary for prevention of re-dislocation. Herein, 2 adult patients with chronic rotatory atlantoaxial dislocation of traumatic origin are presented. In both cases, cranial traction and manipulations were ineffective and therefore an open reduction procedure was proposed and accomplished via the posterior midline corridor. The transverse rod technique was implemented subsequent to the atlantoaxial facet release. After correction of the deformity, a C1-C2 fixation was accomplished followed by arthrodesis. In addition to the outlined procedure, an historical review of the literature on this subject from the beginning of 20th century is demonstrated.

Abstract
Background Traumatic atlanto-axial rotatory subluxation (AARS) in an adult is a rare condition, which if left untreated can be fatal. In addition to this, many symptoms experienced such as neck pain and stiffness are non-specific which often leads to misdiagnosis, thus delaying definitive treatment. AARS can be divided into traumatic and non-traumatic causes with the latter generally encompassing congenital cervical spine abnormalities. Case presentation We present a case of a 66-year-old female with traumatic rotatory AARS, which was initially misdiagnosed in the emergency department. This patient was subsequently recalled to the hospital when the misdiagnosis was spotted the following day from imaging results. The patient was initially managed conservatively as an inpatient using head halter cervical traction which proved to give good clinical reduction allowing discharge with Miami J upon ambulation. Upon follow up the patient was experiencing continuous pain but remained neurovascularly intact. She thus opted for definitive management with C1–C2 stabilization with an open reduction and internal fixation. Conclusion This case demonstrates the importance of having a high index of suspicion to diagnose AARS in cervical spine trauma presenting to the emergency department, until exclusion can be made using imaging and clinical examination.

Abstract
Atlanto-axial rotatory-subluxation (AARS) is the most common pediatric cervical spine injury. Patients usually present with contralateral rotation and inclination of the upper cervical spine after minor trauma, or associated with an infection of the upper respiratory tract. According to the authors, initial management of patients with acute and chronic AARS type I-II should comprise closed reduction and immobilization with a cervical collar or a Halo-Body-Jacket. Surgical options of open reduction or C1/2 fusion should be restricted to irreducible or recurrent subluxations. This paper reviews the detailed technique of transoral closed reduction of AARS, as well as the preoperative and postoperative considerations.

Abstract
Atlanto-axial subluxation is a rare but potentially serious complication after otolaryngological procedures. We are describing a case of a 4-year-old child who developed atlanto-axial subluxation of the cervical spine after adenoidectomy. Our patient underwent adenoidectomy and, 18 days later, presented to the emergency department with her neck tilted to the left in a cock-robin position and complaining of neck pain persisting since the surgery. A multiplanar 3-dimensional computed tomography was obtained and confirmed the diagnosis of an atlanto-axial subluxation (Fielding type 3). She was managed conservatively with the application of a cervical collar, anti-inflammatory medication, and manual reduction under anesthesia later in the course because of persistence of her symptoms. It is important to consider this diagnosis in any child who undergoes ENT surgical procedures complaining of neck pain subsequent to surgery or holding the head in a fixed position persistently after surgery. Early diagnosis is important to reduce the time between the onset of symptoms and reduction to reduce the risk or need for surgical intervention.

Abstract
INTRODUCTION Atlantoaxial rotational fixation (AARF) is a rare entity in adults, with only a few cases reported in the English literature and often associated with a traumatic mechanism. It is an underdiagnosed condition that must be taken into account in the initial assessment of all craniocervical trauma. Both diagnostic and therapeutic delay may be a potential cause of severe neurological damage or even death of the patient. The therapeutic management is controversial given the difficulty of achieving optimum stability and permanent reduction. METHODS AND RESULTS A 28-year-old woman was involved in a traffic accident a week before coming to the emergency with rotation and irreducible cervical flexion from trauma and severe neck pain. CT and MRI column were performed and showed a cervical spinal AARF with transverse and alar ligaments intact and preserved atlantoaxial distance (Fielding I). The patient was treated by progressive cervical traction with 5 kg and manual reduction was completed in 24 h. Subsequently, an external immobilization was performed by cervical rigid collar for 16 weeks. The clinical course was good, with the patient regaining full mobility with cervical neck pain improvement. CONCLUSIONS The purpose of this paper is to show a case of a young woman with a posttraumatic AARF successfully treated conservatively. This case delineates the difficulties in diagnosing this pathology, as well as the challenges encountered in its management.

Abstract
Atlantoaxial rotatory fixation (AARF) is a rare condition and delayed diagnosis. We report a case of chronic neglected atlantoaxial rotatory subluxation in adolescence child that was treated by serial skull traction followed by posterior fusing by method pioneered by Goel et al. A 15-year-old male presented with signs of high cervical myelopathy 2 years after trauma to neck childhood. There was upper cervical kyphosis, direct tenderness over C2 spinous process, atrophy of both hand muscles with weakness in grip strength. Reflexes in upper and lower extremities were exaggerated. Imaging showed Type 3 (Fielding and Hawkins) rotatory atlantoaxial dislocation (AAD). Treatment options available were 1. Staged anterior Transoral release & reduction followed by posterior fusion described by Govender and Kumar et al, 2. Posterior open reduction of joint and fusion, 3. Occipitocervical fusion with decompression. Our case was AARF presented to us with almost 2-year post injury. Considering complications associated with anterior surgery and posterior open reduction, we have opted for closed reduction by serially applying weight to skull traction under closed neurological monitoring. We have serially increased weight up to 15 kg over a period of 1 week before. We have achieved some reduction which was confirmed by traction lateral radiographs and computerized axial tomography scan. Residual subluxation corrected intra-operatively indirectly by using reduction screws in Goel et al. procedure. Finally performed for C1-C2 fusion to take care of Instability. We like to emphasis here role of closed reduction even in delayed and neglected cases.

Abstract
INTRODUCTION The horizontal synchondroses of the infant axis are biomechanical weak regions in trauma. CASE We report the case of a 6-year-old girl who presented with delayed atlantoaxial dislocation and displaced ossiculum terminale epiphysiolysis after a fall from a tree. TREATMENT The patient was treated with halo traction for 3 days after which a CT scan showed normal position of the C1/C2 joint, and an acceptable position of the ossiculum terminale whereafter a halo brace was applied. Because of delayed union on CT scans, the treatment was prolonged to a total of 21 weeks. RESULT At final follow-up 26 months after halo brace removal, the patient demonstrated normal range of movement of the neck on clinical examination and radiographs of the cervical spine including lateral flexion/extension radiographs showed no sign of instability of the atlantoaxial joint. DISCUSSION Conservative treatment with a halo device versus surgical treatment is discussed.

Abstract
Atlantoaxial rotatory fixation (AARF) is a relatively rare condition and is mainly seen in children. We report of a 7-year-old girl suffering from AARF after cochlear implantation (CI). Fortunately, early diagnosis based on three-dimensional computed tomography (3DCT) was made, and the patient was cured with conservative therapy. Nontraumatic AARF, which is also known as Grisel's syndrome and occurs subsequent to neck infections or ear, nose, and throat (ENT) surgery, represents only a small fraction of AARF cases. Two factors are mainly thought to contribute to the pathogenesis of the condition estimated, namely, (i) neck immaturity in children and (ii) infiltration by inflammatory mediators around the upper neck joint, easily permitted by the neck vasculature. AARF should be suspected in case of torticollis developing after ENT surgery.

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVE To introduce a new type of atlantoaxial rotatory fixation (AARF) with a locked C1-C2 lateral facet and evaluate its therapeutic strategy. SUMMARY OF BACKGROUND DATA AARF presenting with torticollis and limited neck motion is commonly seen in teenagers. Fielding and Hawkins' classification is generally applied to AARF. Although conservative treatment is effective for acute AARF, it is often unsuccessful for chronic AARF, which ultimately requires surgery. We introduce a new type of chronic AARF with a locked C1-C2 lateral facet that does not fit into Fielding and Hawkins' classification and describe the appropriate treatment. METHODS Eight patients who had chronic AARF with a unilaterally locked C1-C2 lateral facet were referred to our clinic. Reduction had failed after traction for 3 to 4 weeks. After open release and reduction using the anterior retropharyngeal approach, we applied posterior C1-C2 transpedicular screw fixation with an autologous iliac bone graft for stage I or II. RESULTS The anterior retropharyngeal approach provided direct access to the C1-C2 locked lateral facet. The patient in an overall poor condition (stage II) underwent delayed posterior C1-C2 arthrodesis. The others (stage I) underwent immediate posterior C1-C2 arthrodesis. All patients were followed up for an average of 14.8 months (5-37 mo). Three-dimensional computed tomography revealed C1-C-2 arthrodesis bone graft fusion after an average of 3.1 months (2-4 mo). There was no recurrence of symptoms and no dislocations or internal fixation device loosening or breakage. CONCLUSION AARF with a locked C1-C2 lateral facet is a new type of AARF that cannot be classified using Fielding and Hawkins' classification. The anterior retropharyngeal approach for the release and reduction of AARF, followed by posterior C1-C2 arthrodesis is an effective therapeutic strategy for AARF with a locked C1-C2 lateral facet.

Abstract
Study Design Case report. Objective We report a case of spontaneous atlantoaxial rotatory fixation (AARF) presenting 9 months after onset in an 11-year-old boy. Methods This is a retrospective case report of spontaneous ankylosis of occiput to C2 following traction, manipulative reduction, and halo immobilization for refractory atlantoaxial rotatory fixation. Results The patient underwent traction followed by close manual reduction and placement of halo immobilization after 6 months of severe spontaneous-onset AARF that had been refractory to chiropractic manipulation and physical therapy. Imaging demonstrated dislocation of the left C1-C2 facet joint and remodeling changes of the C2 superior facet prior to reduction, followed by near complete reduction of the dislocation after manipulation and halo placement. Symptoms and clinical appearance were satisfactorily improved and the halo vest was removed after 3 months. At late follow-up, computed tomography demonstrated complete bony ankylosis of the occiput to C2. The patient was found to be HLA B27-positive, but he had no family history of ankylosing spondyloarthropathy or other joint symptoms. The underlying reasons for spontaneous fusion of the occiput to C2 could include the traction, HLA-B27-related spondyloarthropathy, or arthropathic changes caused by traction, reduction, the inciting insult, or immobilization. Conclusion When discussing treatment of childhood refractory AARF by traction, closed manipulation, and halo immobilization, the possibility of developing "spontaneous" ankylosis needs to be considered.

Abstract
Spine involvement is less common in Reiter's syndrome than in other seronegative spondyloarthropathies. Also, cervical spine involvement rarely occurs in Reiter's syndrome and other spondyloarthropathies. This paper reports a rare case of Reiter's syndrome in which there was cervical spine involvement that presented clinically as an atlanto-axial rotatory subluxation. Reiter's Syndrome (RS) is one of the most common types of seronegative spondyloarthropathies (SSAs) that presents clinically with a triad of symptoms, i.e., conjunctivitis, urethritis, and arthritis. This case highlighted the importance of radiographs of the lateral cervical spine and dynamic cervical imaging for all patients who have Reiter's syndrome with cervical spine symptoms to ensure that this dangerous abnormality is not overlooked.

Abstract
PURPOSE The purposes of this study were to characterize the clinical and radiological features of type 1 and type 2 atlantoaxial rotatory dislocations (AARD) and to evaluate the outcome of the manual reduction maneuver for these types of dislocations in pediatric patients. METHODS This study considered 12 pediatric patients with AARD who were treated between January 2003 and March 2013. The diagnosis was established by clinical findings and 3D-CT. All of the patients were treated by closed manual reduction and then a cervical orthosis was performed. All of the patients were followed up at regular intervals. RESULTS The causes of the AARD were trauma (91.67 %) and infection (8.33 %). The time between onset of symptoms and admission to the hospital ranged from 16 days to 6 months. In radiological evaluation, the mean rotational angulation of the patients was 30.58°. The 3D-CT examination showed that six patients (50 %) had type 1 dislocation and six patients (50 %) had type 2 dislocation. All of the patients were treated by closed manual reduction and then a cervical orthosis was performed. For 11 patients (91.67 %), dislocation was successfully reducted and maintained. One patient (8.33 %) underwent surgery, following recurrence of the second closed reduction maneuver. CONCLUSION This preceding treatment method has successfully produced a fast and recurrence-free alignment on all except one of our patients. This technique can be a useful treatment alternative in carefully selected AARD cases. Future research is encouraged to improve decision making in the application of this treatment method and provide additional validation of the current findings.

Abstract
Traumatic atlantoaxial rotatory fixation is a very rare injury in adults which is often misdiagnosed initially. Its combination with C2 fractures is predominated by dens lesions. Therapeutic management is challenging because of the difficulty to achieve optimal reduction and permanent stability. We report a rare case of traumatic atlantoaxial rotatory fixation in a 56-year-old women associated with C2 articular facet fracture successfully treated by conservative means after patient-awake manual reduction with optimal functional and radiographic outcome.

Abstract
We presented a very rare case of adult Fielding type I atlantoaxial rotatory fixation (AARF). We performed awake manual reduction of the dislocation without need for anesthesia, achieving excellent outcomes, and no previous reports have described awake reduction without the need for anesthesia. AARF in this case was attributed to excessive extension and rotation forces applied to the cervical spine. For the management of adult Fielding type I AARF, early diagnosis and early reduction may lead to excellent outcomes.

Abstract
BACKGROUND A rare, but important cause of torticollis in children is atlantoaxial rotatory fixation. If the patient remains undiagnosed for more than three months, surgery is generally the only therapeutic alternative. In this article we present our experiences of surgical treatment of late-diagnosed atlantoaxial rotatory fixation in children. MATERIAL AND METHOD This article is based on a review of the case notes of patients who underwent surgery for atlantoaxial rotatory fixation in the Department for Neurosurgery at Oslo University Hospital, Rikshospitalet, during the period 2004-10. RESULTS The material sample consists of six children aged from seven to 14 years. Five had suffered minor trauma to the upper neck region, while one had had an upper respiratory tract infection. The diagnosis was made 5-36 months after the onset of symptoms. In three of the patients, an attempt was made at closed reduction without success. A CT scan one year postoperatively showed a normal position of the atlantoaxial joint in two patients and partial reduction in three. In the sixth patient there was bone fusion at the time of the operation, and open reduction was unsuccessful. All six patients had reduced rotational movement of the neck at the one-year check-up. INTERPRETATION All our patients were diagnosed more than five months after the onset of symptoms. Full or partial reduction was achieved in five of the six.

Abstract
The purpose of this study was to define a new clinical classification of atlantoaxial dislocation based on its clinical manifestations, namely reducible atlantoaxial dislocation (RAAD), irreducible atlantoaxial dislocation (IAAD), and fixed atlantoaxial dislocation (FAAD). A total of 107 patients with atlantoaxial dislocation were respectively treated based on this clinical classification, including 66 patients with RAAD, 39 patients with IAAD, and 2 patients with FAAD. Six of the 66 patients with RAAD with rotatory atlantoaxial dislocation were treated with traction and a cervical collar, 9 with fresh type II dens fracture were treated with cannulated screw fixation, and 51 were treated with posterior atlantoaxial or occipitocervical arthrodesis. Thirty-eight patients with IAAD received a transoral atlantoaxial reduction plate system, and 1 with a giant cell tumor was treated with lesion resection and vertebral reconstruction by a shaped titanium mesh system followed by posterior occipitocervical screw-rod fixation. The 2 patients with FAAD underwent anterior decompression and received a transoral atlantoaxial reduction plate system. Follow-up data were obtained for a minimum of 6 months. All patients' neurological symptoms improved postoperatively. Bony union was accomplished by 3-month follow-up. Donor-site infection was found in 1 patient, with no occurrence of other complications. This article proposes a new classification of atlantoaxial dislocation indicating the severity and difficulty in reduction of the atlantoaxial joint. The classification system assists with decision making regarding therapeutic options. Transoral atlantoaxial reduction plate fixation and posterior atlantoaxial screw-rod fixation are commonly performed for atlantoaxial dislocation.

Abstract
Atlantoaxial rotatory dislocation (AARD) is a rare complication in adults usually leading to pain, spinal cord injury, or death. Clinical and radiological diagnosis is difficult and often delayed. We report a rare case of posttraumatic AARD in a neurological intact 27-year-old male in which initial radiographic evaluation was negative. A computed tomography (CT) scan was promptly done because the patient showed a severe torticollis. Therefore, early diagnosis, immobilisation, and surgical fusion and arthrodesis were performed. After surgery, cervical pain and torticollis were resolved and the patient remained neurologically intact with a CT scan documentation of fusion at the 3-year followup.

Abstract
STUDY DESIGN Retrospective case series of chronic atlantoaxial rotatory fixation (AARF) treated by a novel closed reduction method (remodeling therapy) and review of the literature. OBJECTIVE To describe clinical features of chronic AARF and the rationale of the remodeling therapy. SUMMARY OF BACKGROUND DATA Treatment strategy for chronic recurrent AARF remains controversial. Posterior C1-C2 arthrodesis has been widely used for recurrent unstable AARFs after the closed reduction, and a variety of posterior fusion techniques have been advocated. In contrast, several investigators reported a chronic AARF case treated by a simple traction or closed reduction followed by cervical immobilization. Previously, we have found that a deformity of the superior C2 facet joint (C2 facet deformity) on three dimensional computed tomography (3D CT) reconstructions is a risk factor for recurrent subluxation. In addition, the remodeling of this C2 facet deformity by careful closed manipulation followed by halo fixation (remodeling therapy) could prevent the recurrence of subluxation. METHODS Twelve children with chronic AARF who sustained torticollis for an average of 4.4 months after the onset were referred to our clinic. The mean age at the initial visit was 7.8 years. All patients underwent the remodeling therapy as reported previously. Radiographic findings and clinical courses were retrospectively reviewed. Treatment methodology, pearls, and pitfalls of the remodeling therapy were discussed with review of the literature. RESULTS 3D CT images before reduction revealed persistent atlantoaxial subluxation and the C2 facet deformity in the dislocated side in all cases. Follow-up 3D CT scans demonstrated the remodeling of the C2 facet deformity at an average of 2.4 months after successful reduction of subluxation. Neither recurrence of symptoms nor subluxation was observed at a mean follow-up of 42 months in any case. The cervical range of motion was 73.9° at the dislocated and 83.5° at the contra-dislocated side from the midline. CONCLUSION Chronic irreducible and recurrent unstable AARF should be initially managed by remodeling therapy using the facet deformity sign as a clinical index, if the C1 and C2 have not been osseously fused.

Abstract
Introduction Atlantoaxial rotatory subluxation is rarely caused by trauma in adults. Usually, the treatment of choice is traction using Halo/Gardner-Wells fixation devices for up to six weeks. Case presentation We present the case of a 19-year-old Caucasian woman with traumatic atlantoaxial subluxation. Early reduction three hours after trauma and immobilization using only a soft collar were performed and yielded very good clinical results. Conclusion In the adult population, atlantoaxial subluxation is a rare condition but is severe if untreated. Early treatment implies a non-surgical approach and a good outcome. Conservative treatment is the recommended first step for this condition.

Abstract
STUDY DESIGN A retrospective case series. OBJECTIVE To propose a novel treatment strategy for chronic atlantoaxial rotatory fixation (AARF). SUMMARY OF BACKGROUND DATA Treatment strategy for chronic or recurrent AARF remains controversial. We have previously reported that a deformity of the superior facet of the axis (C2 facet deformity), which is frequently observed in patients with chronic AARFs, is a risk factor for recurrent dislocation. In this article, we report seven consecutive cases of chronic AARF who underwent closed manipulation followed by external halo fixation and maintained good reduction with the remodeling of the C2 facet deformity. METHODS Seven girls with a chronic AARF who sustained torticollis for an average of 4.6 months after the onset were referred to our clinic. Closed manipulation by careful manipulation under general anesthesia followed by external immobilization with a halo vest was performed in all cases. Radiographic findings and clinical courses were retrospectively reviewed with approvals by the institutional review board. RESULTS Three-dimensional computed tomography images before reduction revealed persistent atlantoaxial subluxation and the C2 facet deformity in the dislocated side in all cases. Follow-up three-dimensional computed tomographic scans demonstrated the remodeling of the C2 facet deformity at an average of 2.8 months after successful reduction of subluxation. Subsequently, the halo vests were removed and gentle neck range of motion exercise was started in all cases. The normal cervical range of motion was obtained 2 weeks after the removal of halo vests in five cases, whereas the range of motion remained limited in two cases. At a mean follow-up of 17.4 months, neither symptoms nor recurrence of subluxation occurred in all cases. CONCLUSION Chronic irreducible and recurrent unstable AARF can be managed successfully by careful closed manipulation followed by halo fixation, if the C1 and C2 have not been osseously fused. The remodeling of the C2 facet deformity detected on follow-up CT scans can be a useful radiographic parameter to determine the appropriate period of halo fixation in this new treatment strategy obviating the need for surgical intervention.

Abstract
Traumatic atlantoaxial rotatory fixation (AARF) with accompanying odontoid and C2 articular facet fracture is a very rare injury, and only one such case has been reported in the medical literature. We present here a case of a traumatic AARF associated with an odontoid and comminuted C2 articular facet fracture, and this was treated with skull traction and halo-vest immobilization for 3 months. After removal of the halo-vest immobilization, his neck pain was improved and his neck motion was preserved without any neurologic deficits although mild torticolis was still observed in closer inspection.

Abstract
STUDY DESIGN Applying rotating rod techniques to reduce irreducible atlantoaxial dislocation. OBJECTIVE To spare the occipital-C1 motion by the strategy in reduction of before surgery irreducible atlantoaxial dislocation with obvious neurologic symptoms and congenital odontoid aplasia. SUMMARY OF BACKGROUND DATA The treatment of atlantoaxial dislocation (AAD) is a challenging problem for most surgeons. Posterior surgical stabilization of C1 and C2 include C1-C2 transarticular screws, or C1 lateral with C2 pars screws. These constructs, however, are based on preoperative reductions. When preoperative skull reduction fails and myelopathic symptoms coexist, long-segment cervico-occipital fusion and decompression are usually the only practical choice. METHODS The authors explored a different surgical technique to spare the axial occipital joints by rotating rods in polyaxial C1, C3 lateral mass, and C2 pars screws, functioning as a lever analogue. Three before surgery irreducible AAD cases with obvious neurologic symptoms and congenital odontoid aplasia were successfully reduced and fused with this procedure. The authors used intraoperative somatosensory-evoked potential monitoring and intraoperative fluoroscopy. Preoperative skull traction was employed to distract and help extend the atlantoaxial complexes. RESULTS Three C1-C2 dislocations were reduced completely without any deterioration of neurologic signs. Cervical myelopathic symptoms recovered soon after the operation. No atlantoaxial subluxation recurred. They returned to their normal work and/or activities. CONCLUSION The rotating rod strategy is a viable option to reduce and fuse C1-C3 for AAD with odontoid aplasia. It spares the occipital-C1 motion.

Abstract
STUDY DESIGN Normal rotation was evaluated in a group of 40 asymptomatic adults. OBJECTIVE To determine the normal rotational limits of C1-C2 in adults and define when a rotatory fixation occurs in the limits of normality or in subluxation. The term subluxation should be used only when C1-C2 is rotated beyond normal limits. SUMMARY OF BACKGROUND DATA Concepts about rotatory fixation were established by accepting that it may occur within the limits of normal range of motion. Although nowadays CT is the current image method used to evaluate any case of torticollis, no study has been performed in adult population on what really normal rotation look like in CT scans. METHODS The study included the measurement of the rotational movement of the neck and a CT scan study of the articular processes of C1-C2 in maximal, left and right, active rotation. A superposition of 6 consecutive slices was carried out, obtaining a linear contour of the axial view of C1-C2. Rotation angle and contact surface loss were measured. RESULTS The average neck rotation angle was 79 degrees (range: 74 degrees to 81 degrees ). The superposition of the images taken in every rotational direction showed a wide contact loss between the correspondent C1-C2 articular surfaces (42.4%-85.7%; average: 70%). The report of these images, carried out by 3 independent radiologists, concluded that there was a rotatory subluxation in all these cases. CONCLUSION Our results coincide with our previous published ones conducted in children, and lead us to conclude that a CT scan showing wide-but incomplete-rotational facet displacement is not sufficient to define subluxation. We perceive that there is a risk of overdiagnosis and overtreatment (C1-C2 arthrodesis) when evaluating upper cervical spine rotational problems. The concept of both rotatory fixation and subluxation should be revised, and quantifying the rotational angle and contact surface loss between C1-C2 can be very useful.

Abstract
Atlantoaxial rotatory fixation (AARF) in adult is a rare disorder that occurs followed by a trauma. The patients were presented with painful torticollis and a typical 'cock robin' position of the head. The clinical diagnosis is generally difficult and often made in the late stage. In some cases, an irreducible or chronic fixation develops. We reported a case of AARF in adult patient which was treated by immobilization with conservative treatment. A 25-year-old female was presented with a posterior neck pain and limitation of motion of cervical spine after a traffic accident. She had no neurological deficit but suffered from severe defect on the scalp and multiple thoracic compression fractures. Plain radiographs demonstrated torticollis, lateral shift of odontoid process to one side and widening of one side of C1-C2 joint space. Immobilization with a Holter traction were performed and analgesics and muscle relaxants were given. Posterior neck pain and limitation of the cervical spine's motion were resolved. Plain cervical radiographs taken at one month after the injury showed that torticollis disappeared and the dens were in the midline position. The authors reported a case of type I post-traumatic AARF that was successfully treated by immobilization alone.

We present a case of atlantoaxial rotary subluxation after a minor injury managed by manual reduction under sedation. Atlantoaxial rotary subluxation should be considered in a child with inability or unwillingness to turn their head when history and physical examination do not suggest torticollis of benign etiology. In our discussion, we review etiology, diagnosis, as well as pre- and in-hospital management.

STUDY DESIGN A case report. OBJECTIVE To describe an interesting patient who underwent open reduction and C1-C2 transpedicular screw fixation with interspinous wiring due to high-riding vertebral artery. SUMMARY OF BACKGROUND DATA Atlantoaxial rotatory fixation (AARF) is a rare complication found most frequently after trauma in children and young adults; the clinical diagnosis is difficult and often made late. METHODS We report a case of post-traumatic AARF associated with a facet fracture in an adult. Reduction proved difficult to obtain by skull traction and gentle manipulation. Therefore, after open reduction under general anesthesia, we performed C1-C2 transpedicular screw fixation with posterior wiring to avoid vertebral artery injury due to high-riding transverse foramen at the C2 vertebra. RESULTS The normal atlantoaxial relation was restored and the torticollis resolved. The patient remains neurologically intact and has radiographic documentation of fusion. CONCLUSION Although technically demanding, C1-C2 transpedicular screw fixation combined with interspinous bone graft wiring after open reduction may be an alternative treatment option if conservative treatment fails to reduce AARF.

Abstract
Cervical spine injuries are rare in children. They tend to occur predominantly in the region of atlanto-axial articulation. Even traumatic rotatory atlanto-axial subluxation (AAD) has been described in the literature, however, there is no consistent therapeutic protocol. We report on a 4 year old girl with an acute traumatic rotatory atlanto-axial subluxation treated with closed reduction and retention in a hard-collar. Control CT scans and physical examination after 6 weeks revealed an excellent outcome without any signs of recurrence. As there is a correlation between outcome and increasing length of the dislocation-therapy interval, optimal management of acute rotatory atlanto-axial subluxation depends on early diagnosis with plain radiography and CT scans. Timely diagnosed cases may be treated successfully with closed reduction and cervical immobilisation in a hard-collar. Failure to obtain reduction and recurrence are an appropriate indication for surgical intervention.

Abstract
Abstract
OBJECTIVE:
This is a prospective study of the clinical manifestations, diagnostic motion analysis, management, and outcome of children with atlantoaxial rotatory fixation (AARF).
METHODS:
Fifty children presenting with painful torticollis were subjected to the three-head positions diagnostic computed tomographic scanning protocol described in Part II of our AARF study. Twenty-nine children qualified as having AARF (8 Type I, 11 Type II, and 10 Type III), and six children were classified in the diagnostic gray zone (DGZ). The AARF patients were given either halter or calipers traction depending on the type and chronicity of pretreatment delay. Upon reduction, patients were immobilized with either a cervicothoracic brace or a halo. Recurrence of AARF on halo and patients whose deformity was not reducible were given posterior C1C2 fusion at the best achievable alignment. The difficulty and results of treatment were measured according to the following: duration of traction, number of reduction slippage, percent not reducible by traction, percent needing halo, percent needing fusion, total duration of treatment, total number of treatment procedures, and percent who lost normal C1C2 dynamics. Results were compared between groups stratified by AARF types, by chronicity of pretreatment delay (acute ≪ 1 mo, subacute = 1–3 mo, chronic ≥ 3 mo) and by the presence or absence of recurrence (recurrent AARF defined as having two or more slippages). DGZ patients were treated with only comfort measures for 2 weeks and then restudied. Only those children with persistent symptoms and DGZ or worse motion dynamics were given traction and bracing.
RESULTS:
Neither age nor etiology significantly influenced the severity of AARF. There was only a slight tendency for children younger than 5 years, and for trauma, to associate with severe C1C2 interlock. Delay of treatment up to 11 months did not result in improvement of the neck restriction or in abatement of pain. In fact, there are strong suggestions that prolonged delay could lead to worsening of the rotatory dynamics: Type I AARF are highly correlated with delays longer than 3 months and Type III with delays less than 1 month. Also, four patients who had serial motion studies during the delay period showed clear worsening in the pathological stickiness in C1C2 rotation. In addition, chronic rotatory deformity led to progressive occiput −C1 separation or laxity teleologically to compensate for a skewed visual axis. The mean occiput −C1 separation angle for chronic patients was 31.2° versus 5° for acute patients and less than 3° for normal children. The difficulty and duration of treatment, the number of reslippage after reduction, the rate of irreducibility, the need for halo and fusion, and the percentile of patients ultimately loosing normal C1C2 rotation were significantly greater with Type I patients than Type III patients, with Type II patients being intermediate. Likewise, chronic patients of all AARF types were much worse in all parameters than acute patients; subacute patients were closer to chronic patients in complexity and outcome. Severity and chronicity exerted independent effects on outcome, and the worse identifiable subgroup were the chronic Type I patients versus the best subgroup of acute Type III patients.
Thirteen patients developed recurrent AARF; they had much worse prognosis in all aspects measured than nonrecurrent patients. Recurrence was adversely influenced by both the severity (type) and chronicity of AARF. Half of the DGZ patients resolved with analgesics, but two of six remained symptomatic and in DGZ dynamics, and one deteriorated to Type III AARF. Two of those three patients responded easily to traction and bracing, and one was lost to follow-up.
CONCLUSION:
Children with painful torticollis should be subjected to the three-position computed tomographic diagnostic protocol, not only to secure the diagnosis of AARF but also to grade the severity of the condition by virtue of the dynamic motion curve. Closed reduction with traction should be instituted immediately to avoid the serious consequences of chronic AARF. Proper typing and reckoning of the pretreatment delay are requisites for selecting treatment modalities. Recurrent dislocation and incomplete reduction should be treated with posterior C1C2 fusion in the best achievable alignment. Open reduction and halo immobilization to avoid permanent fixation can be tried with select cases.
