Os Odontoideum Treatment & Management: Approach

  1. In a small series, Hong et al concluded that the Harms C1-2 polyaxial screw-and-rod technique was the most appropriate treatment for patients with os odontoideum. In Park and coworkers' series of pediatric atlantoaxial instability, 58% had an anomalous course of the vertebral artery and 42% had anomalous C1-2 bony anatomy
  2. The main method of surgical treatment today is posterior decompression after reduction and fusion via independent C1 and C2 instrumentation. Irreducible, persistent anterior compression from os odontoideum can be approached by a transoral route with good results in experienced hands
  3. Non-surgical os odontoideum treatment Children with mild os odontoideum may not need surgery. They should see a spine specialist regularly to monitor their spine over time and watch for any signs of progression or spinal cord damage. Physical therapy, a cervical collar, or pain medication may be prescribed to control symptoms
  4. imum duration of follow-up of 2 years. Thirty-one children had nonoperative treatment, and 71 underwent instrumented posterior cervical spinal arthrodesis for the treatment of C1-C2 instability
  5. Active surgical treatment should be considered even in patients with os odontoideum who exhibit mild symptoms. In most patients with os odontoideum, use of the C1-2 polyaxial screw and rod technique may be the most appropriate treatment. In patients with dystopic os odontoideum, O-C fusion should be considered
  6. Various methods have been described for the treatment of symptomatic os odontoideum, all of which have limitations. METHODS: Nineteen patients with symptomatic os odontoideum were investigated. Pain scores were assessed using the visual analogue scale. Myelopathy was assessed using the Nurick scale and Odom's criteria

Physical Therapy For people with os odontoideum, if the joint appears to be stable, physical therapy may be considered to ease symptoms. The fundamental goal of physical therapy is to enhance the function of the spinal subsystems and reduce the stress on the spinal cord Surgical techniques to stabilize and fuse across the craniocervical junction with or without C1 laminectomy and techniques that provide ventral decompression have been reported in the treatment of os odontoideum with irreducible neural compression (6, 24) There is a role for conservative treatment of an asymptomatic incidentally found, radiologically stable and non-compressive os odontoideum. However, surgical treatment has a definitive role in symptomatic cases. In this study, the case is presented of a 31 year-old male patient with neck pain who was diagnosed with incidental os odontoideum

Nonsurgical treatment of type II odontoid fractures consists of either rigid collar fixation or halo immobilization Atlantoaxial segmental stabilization resulted in clinical symptomatic and neurologic improvement in 100% of patients. CONCLUSIONS: Os odontoideum signifies chronic or long-standing atlantoaxial instability. Segmental atlantoaxial fixation is a reliable form of surgical treatment. Bone decompression is not necessary Patients who have os odontoideum with a reducible atlantoaxial dislocation can be effectively treated with single-level posterior fusion and stabilization. Combined transoral decompression and posterior fusion and stabilization is recommended for those with irreducible atlantoaxial dislocation

Physical therapy is considered when the patient is still young or when there is no radiographic evidence of significant instability, neurological symptoms or uncontrollable pain. The therapy consists of traction and three to six months in a Minerva jacket or a brace. In most patients leads this therapy to fusion of the atlanto-axial joint Os-odontoideum signifies chronic or longstanding atlantoaxial instability. Segmental atlantoaxial fixation is a reliable form of surgical treatment. Any form of bone decompression is not necessary. Inclusion of occipital bone and subaxial vertebrae in the fixation construct is not necessary 8)

Os odontoideum: etiology and surgical managemen

The authors examined the clinical presentation and outcome in patients with os odontoideum who underwent surgical stabilization, with an emphasis on 3 patients who initially received conservative treatment and suffered delayed neurological injury. Methods. Seventy-eight patients (mean age 20.5 years; median 15 years) were identified in a 17. The most contentious issue in the management of os odontoideum surrounds the decision to attempt atlantoaxial fusion in patients with asymptomatic lesions Odontoid fractures are relatively common fractures of the C2 vertebral body (axis) that can be seen in low energy falls in eldery patients and high energy traumatic injuries in younger patients. Treatment depends on the location of the fracture within the C2 vertebrae defined by the Anderson and D'Alonzo classification system and the patient's risk factors for nonunion (failed bone healing)

Os odontoideum (OO) is a rare anomaly of the odontoid process first described by Giacomini in 1886. There is considerable debate about the origin of this anomaly, whether congenital or acquired, though a growing body of evidence favors the latter. Using PubMed, we reviewed the literature on OO with regards to its etiology, clinical presentations, diagnostic modalities, and management Common symptom. Stress. How bad it is. 1 a os odontoideum patient reports severe stress (100%) 0 os odontoideum patients report moderate stress (0%) 0 os odontoideum patients report mild stress (0%) 0 os odontoideum patients report no stress (0%) What people are taking for it. Nothing reported yet We reviewed the data for 102 children with os odontoideum who were managed at 11 centers between 2000 and 2016 and had a minimum duration of follow-up of 2 years. Thirty-one children had nonoperative treatment, and 71 underwent instrumented posterior cervical spinal arthrodesis for the treatment of C1-C2 instability Degenerative cysts associated with an unstable os odontoideum in pediatric patients are uncommon lesions. Reported treatments of such lesions have varied and yielded mixed results with the optimal surgical strategy remaining unclear. The authors report the clinical and surgical outcome of a 13-year-old patient presenting with degenerative cyst adjacent to an abnormal os odontoideum motion.

  1. Os Odontoideum Os means bone and odontoideum refers to the odontoid process, or the dens, which is a part of the second bone in your spine—the axis, or C2. The dens fits into a groove in the C1 bone, or atlas, and it enables your head and neck to move properly. In os odontoideum, a portion of the dens is removed from the.
  2. We report on a 36-year-old man presenting with a sudden onset of motor weakness and numbness in the upper extremities following a fall from a truck bed. Radiological findings demonstrated an os odontoideum and osseous continuity between the occiput and an ossicle, termed an occipitalized os odontoideum
  3. In Os Odontoideum, there is a joint-like articulation between the Odontoid and the body of the Axis (the C2 vertebra). This gap may be confused with a normal finding in patients younger than 5 years. In children, the diagnosis must be confirmed by demonstrating motion between the Odontoid and the body of the Axis
  4. In the orthotopic type of the condition, os is in its normal position and it maintains a normal relationship with the clivus, atlas and the axis (Figure 1), thus, available for free movement with the anterior arch of the atlas.

  5. Os odontoideum is a condition in which the odontoid process is an ossicle, detached from the body of the axis, which can lead to instability of the atlantoaxial joint. 2 It is usually an incidental finding but has been associated with severe spinal cord and vertebral artery injury. 2, 3 This case also exemplifies the standard of care for.

Os odontoideum combined with cervical spondylotic myelopathy, both of which require surgical treatment is even more rare, there was only one such case in the literature. Methods: We describe a 68-year-old male who underwent C1-C2 posterior screw-rod fixation for os odontoideum an Summarize the treatment of os odontoideum. Explain how early recognition of os odontoideum by the interprofessional team is imperative to guide proper specialist referral required to manage this condition, provide patient and family education, and improve outcomes avoiding complications derived from cervical instability and cord compression treatment of Os odontoideum in the pediatric population. Embryology and Etiology The atlas and the axis are two unique and complex embryologic structures whose development relies on differentiation of the cervical and spinal sclerotomes [9-11]. More specifically, the fourth occipita Os odontoideum was discovered, and a C1-C2 fixation procedure resolved his symptoms.13 A further case has been described by Kikuchi where bilateral vertebrobasilar insufficiency due to atlantoaxial instability in the presence of Os odontoideum has led to ischaemic stroke.1 Os odontoideum is a congenital or posttraumatic abnormality of the second cervical vertebrae in which the odontoid process is separated from the body of the axis by a transverse gap. 1 This lesion can look like a fracture at the base of the odontoid. The lesion is frequently asymptomatic. Discovery of this cervical abnormality in an active-duty.

Os odontoideum is a rare lesion, and its pathogenesis has been extensively debated in the literature. Some authors have argued that it is congenital and represents the centrum of atlas. However, most authors believe that it is a result of trauma leading to a chronic non-united fracture of the odontoid process [ 3 ] Os Odontoideum-A review Dr.M.Ashok kumar M.S.(Ortho),FSS (CMC-Vellore) Consultant Spine Surgeon, SNHRC, Vellore

Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Os Odontoideum Os odontoideum is defined as an ossicle with smooth circumferential cortical margins representing the odontoid process that has no osseous continuity with the body of C2. Here, we describe a case of os odontoideum combined with cervical spondylotic myelopathy (CSM), which require surgical treatment. We performed C1-C2 posterior screw-rod. Tanaka et al. proposed the C1-C2 fixation with laminectomy as surgical treatment of types 1 and 2 . In this case, os odontoideum is the cause for the AII with ROP.

An uncommon case mimicking cervical trauma: Os odontoideum

Os odontoideum It is the most common developmental anomaly of odontoid. The definition of an os odontoideum is uniform throughout the literature: An ossicle with smooth circumferential cortical margins representing the odontoid process that has no osseous continuity with the body of C2.[25] The origin of os odontoideum Os Odontoideum (OO), known as a rare anomaly of the cervical spine and can be confused with fracture, involves the second cervical vertebrae, which is characterized by the separation of a portion of the odontoid process (also known as dens) from the body of the axis. 1,2 It was first described by Giacomini in 1886, and whether the etiology of OO is congenital or traumatic has remained. Untreated patients with Laron syndrome develop cervical spinal stenosis and early osteoarthritic changes of the atlantoaxial joint, and have a small oropharynx. Laron syndrome is associated with os odontoideum. These findings stress the need for IGF-1 replacement treatment in these patients early in childhood Between January 1981 and December 1985 at the Rizzoli Orthopaedic Institute 8 patients affected with atlo-axial instability secondary to os odontoideum were submitted to surgery: all of the patients were characterized by persistent cervical pain and neurological deficit, which was still at an initial stage in 5 cases, and more severe in the remaining 3 (severe spastic tetraparesis) An os is a well rounded ossicle with defined borders above the level of the C1-C2 facets. This represents an unstable finding with resultant C1-C2 instability in both flexion and extension. Treatment of os odontoideum is surgical to avoid neurologic injury

Introduction. Os odontoideum (OO) or separate odontoid; is a well-known pathology that was described for the first time in the 19th century. The term OO is of a Latin origin and is composed of Os (bone) and odontoideum (tooth-like) [1-4].This pathology is mostly diagnosed in children and young adults, although its discovery in the middle aged individuals is not infrequent [1-9] We describe the case of a symptomatic early dystopic os odontoideum in a very young child. Os odontoideum is a rare congenital anomaly of C2, first described by Giacomini in 1886 Reference Giacomini 1 and characterized by a smooth, independent ossicle separated from the base of an abnormal odontoid process and without osseous connection to the body of C2 Results of Conservative and Surgical Management in Children with Idiopathic and Nonidiopathic Os Odontoideum CPT 22319 Open treatment and/or reduction of odontoid fracture(s) and or dislocation(s) (including os odontoideum), anterior approach, including placement of internal fixation; with grafting CPT 22548 Arthrodesis, anterior transoral or extraoral technique, clivus-C1-C2 (atlas-axis), with o

Diagnoses included instability related to skeletal dysplasia, os odontoideum, congenital deformities, basilar invaginations, cervical spine tumors and spinal fracture. In the majority of cases, the decision to use translaminar screws was made preoperatively due to distortions in the patients' anatomy that made it impossible to use pars screws Keywords: Os Odontoideum, Myelopathy, Odontoidectomy 1. Introduction Os odontoideum (OO) is a form of odontoid anomaly; other forms of this anomaly are aplasia and hypoplasia (1). The os odontoideum is a separate bone with smooth, roundedcorticalmargins, usuallyabouthalf thesizeof the odontoid process. The gap between the os odontoideum Os odontoideum is characterized as one of two types: Orthotopic or dystopic. An orthotopic os is located in the expected anatomic location along the superior margin of the base of the dens. When unstable, it often articulates with the anterior arch of C-1 independent of the base of the dens; atlanto-dental instability may also be seen [Figures. Os odontoideum or separate odontoid is defined as a round, ossicular remnant of the dens that is not fused to the body of the C-2 vertebra [3-5]. Whether the os odontoideum is a developmental anomaly or an acquired lesion is debated in the literature [3, 5, 17-24] Os odontoideum este o afecțiune rară care implică al doilea os din spate.
