Atlantoaxial rotatory subluxation: realignment and discharge within 48???h

Interventional magnetic resonance imaging as a diagnostic and therapeutic method in treating acute pediatric atlantoaxial rotatory subluxation

Atlantoaxial rotatory subluxation or fixation (AARF) is a rare condition, usually occurring in pediatric patients. It mimics benign torticollis but may result in permanent disability or death. The condition requires prompt diagnosis by thorough examination to avoid any treatment delays. Spiral computed tomography (CT) with three-dimensional reconstruction CT is recommended for identifying incongruence between C1 and C2 vertebrae, and magnetic resonance imaging (MRI) may be performed to exclude ligamentous injuries. In addition to static imaging, dynamic CT involves the reduction between C1 and C2 being confirmed using CT with the head turned maximally to the left and right. The present report (level of evidence, III) provides a method for treating AARF that has similar advantages as dynamic CT but avoids ionizing radiation by replacing CT with interventional MRI. The new method comprised simultaneous axial traction and manual closed reduction, performed under general anesthesia, and the use of interventional MRI to ensure that reduction was achieved and held. The head is turned maximally to the right and left during the manual reduction. A rigid cervical collar was used following reduction. Dynamic CT was not required but prior diagnostic static CT was performed in preparation. No further CT was required. There appears to be no previous studies on interventional MRI in AARF care. Being superior in its diagnostic soft-tissue visualization performance and lacking ionizing radiation, interventional MRI is a potential option for investigating and treating acute AARF in non-syndromic patients with no trauma history.

A 30-year-old Male with Delayed Diagnosis and Management of Chronic Post-traumatic Atlantoaxial Rotatory Subluxation

Introduction:

Atlantoaxial rotatory subluxation (AARS) is an uncommonly encountered diagnosis within the adult population. The rare nature of this dislocation within the adult population often results in delayed diagnosis and treatment.

Case Report:

A 30-year-old male presented following a low-speed motor vehicle accident. The patient had been involved in a work-related accident 1-year prior and had experienced fixed leftward gaze and tenderness of the cervical spine following this incident, but exhibited no focal neurologic deficits. Imaging demonstrated a Fielding Type 1 AARS of approximately 45°. The subluxation was reduced; and posterior C1–C2 instrumentation and fusion were performed, with no complications. Post-operative imaging revealed maintained reduction and alignment. The patient regained acceptable alignment and relief from his pre-operative symptoms.

Conclusions:

Our case is an illustration of a chronic post-traumatic AARS in an adult patient with delayed diagnosis and definitive management. This diagnosis is rare within the adult population and is frequently overlooked. A high index of suspicion must exist when evaluating adult patients with clinical presentations of chronic neck pain, torticollis, or “cock robin” head positioning as delayed diagnosis.

Closed manual reduction maneuver of atlantoaxial rotatory dislocation in pediatric age

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.

Traumatic atlantoaxial rotatory subluxation in an adolescent: a case report

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.

Traumatic bilateral atlantoaxial rotatory subluxation mimicking as torticollis in an adult female

Rotatory subluxation of the atlantoaxial joint in adults is a rare, but potentially life-threatening injury. Delayed or missed diagnosis can lead to catastrophic consequences. Early recognition and prompt treatment is paramount to avoid long-term morbidity and disability. We report on an instance of bilateral atlantoaxial rotatory subluxation (AARS) in a 25-year-old female who presented to the Casualty Department with a painful neck, right-sided hemiparesis and torticollis after a road traffic collision. Reduction was achieved by controlled cervical traction followed by immobilization in a four-post Halo brace, with complete resolution of her symptoms. At the 12-month follow-up, she had normal neck movements with no signs of instability.

Comanagement and collaborative care of a 20-year-old female with acute viral torticollis

OBJECTIVE

This case study describes a patient diagnosed with acute viral torticollis and illustrates the relevant aspects of differential diagnosis and the collaborative efforts between the chiropractic and allopathic disciplines in establishing an optimum treatment protocol provided by comanagement of the case.

CLINICAL FEATURES

A 20-year-old female student experienced a sudden onset of neck pain and inability to move her neck in conjunction with an antalgic attitude of her cervical spine in lateral flexion and rotation. Physical examination revealed an elevated temperature indicating the possibility of infection. Associated symptoms included headache, nausea, vomiting, and malaise.

INTERVENTION AND OUTCOME

The patient was initially assessed in a teaching clinic of a university medical health center for acute meningitis. A consultation was requested by the senior attending physician for an opinion by the chiropractic services of the university health center to assess the patient for nuchal rigidity and to provide treatment of the torticollis. After an evaluation of the status of the patient, a diagnosis of acute viral torticollis was established, and chiropractic manual therapy was initiated with a significant improvement in the ability of the patient to execute cervical ranges of motion without undue limitation and pain. Follow-up chiropractic care resulted in resolution of the torticollis without residual symptoms.

CONCLUSION

Acute viral torticollis occurring in a young adult with associated symptoms of fever, headache, nausea, and vomiting presents a diagnostic challenge in excluding the possibility of meningitis. Appropriate clinical and physical examination procedures are essential to exclude the latter while providing the clinician with the confidence to proceed with conservative management of the patient. Comanagement and collaborative care between the medical and chiropractic disciplines offered the patient a treatment plan with prompt resolution of symptoms.

Atlantoaxial rotary subluxation after minor trauma

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.
