In transdental injuries of atlantoaxial region the indications for conservative treatment and authors bipolar Halo-traction method were worked out on the base of spine biomechanical peculiarities (anterior shifting moment and extensor conditionality of the posterior cervical muscles) as well as depending on the mechanism of the development of plane fracture of C2 odontoid process. In flexion fracture of the odontoid process without dislocation as well as in extension fracture with dislocation within the limits of 1/3 of its diameter the successful conservative treatment with plaster thoracocranial bandage was possible. In the rest of cases the authors method of bipolar Halo-traction was indicated. The experience of treatment of 32 patients was used in the work.

Study Design. A case report and review of the literature.Objective. The aim of this study was to describe the conservative management of pyogenic spondylitis around the odontoid process.Summary of Background Data. Atlantoaxial subluxation after pyogenic spondylitis is rare. The therapeutic approach to infection of the upper cervical spine is controversial.Methods. Medical chart and radiological images of a 76-year-old male patient were retrospectively reviewed. Radiography revealed atlantoaxial subluxation, and an abscess was seen around the odontoid process on magnetic resonance images. Intravenous antibiotics and a halo vest were used to treat the patient. We then observed the patient’s conservative treatment course.Results. C-reactive protein levels returned to normal 4 weeks after administration of the intravenous antibiotics. The patient’s muscle weakness also completely recovered 8 weeks after administration of the intravenous antibiotics. Because the patient was able to walk without any support, surgical treatment was not necessary.Conclusions. Pyogenic spondylitis of the upper cervical spine is a rare manifestation. Surgical or conservative treatment must be selected carefully based on the patient’s symptoms. If early diagnosis and treatment can be provided to the patients, conservative treatment can be achieved.

Odontoid Process Fracture

Abstract In small childrens spine injuries are rare. In this age group upper cervical spine is commonally affected. Odontoid process fracture involve only a subset of cervical spine fractures. In small childrens, this fracture typically involves the cartilaginousplate that separates the odontoid process from the body of the axis. Odontoid processfracture is rare in children less than 7 years of age.

Abstract For the past 20 years, the transoral approach to the upper cervical spine has been utilized for odontoid fractures, the removal of an abnormal odontoid process, decompression of basilar impression, and biopsy or resection of nasopharyngeal or metastatic tumors. The effectiveness and safety of this procedure is well documented. Use of the surgical microscope adds to the efficiency and safety of the procedure. We are reporting a case of fusion of the odontoid base to the anterior arch of the atlas. To our knowledge, this entity has not been described previously. The spinal cord was protected by an initial posterior fusion of C-1, C-2, followed in 10 days by a tracheostomy and the transoral removal of the anterior C-1 arch and the abnormal dens. Because the medical history did not reveal a source of trauma, it is supposed that the patient had malunion of the odontoid process to C-2, with subsequent migration and fusion of the dens to the C-1 arch.

Comprehensive diagnostics, accepted classifications, and selection of pathogenetic methods of treatment (including surgery) for axis injuries, odontoid process fractures, axis traumatic spondylolisthesis and hangman’s fractures are discussed in the paper. The presented data prove the necessity and possibility of early exhaustive diagnosing to differentiate the type of a craniocervical disorder and to provide a timely choice of pathogenetic treatment technique, especially of a surgical one.

The experience of diagnostics and treatment of 82 patients with various injuries of the upper cervical spine was analyzed. The most frequent injuries were fractures of C2 odontoid process and arch. The treatment included a wide application of halo apparatus, and, when indicated, a surgical instrumention stabilization of the upper cervical spine.

Objectives. To analyze the outcomes of halo-traction for treatment of the upper cervical spine injuries. Materials and Methods. The outcomes of treatment of 354 patients with the trauma of the cervical spine were analyzed. Out of them 150 patients had injuries of С1–С2 (42,4 %). Bipolar halo-traction was used for treatment of fresh, old and neglected injuries with fragment dislocations in the upper cervical spine. Clinical, radiological and CT examinations of the cervical spine were performed. Results. Bipolar halo-traction was performed in 31 out of 59 patients with transdental dislocations, in 14 out of 26 patients with traumatic spondylolisthesis, and in 9 out of 13 patients with multifocal disorders. Monopolar halo-traction was used in 3 out of 7 patients with С1 Jefferson fractures. Satisfactory results were achieved in 47 out of 48 patients treated by halo-traction. The treatment has failed in one patient with a false joint of the dens and atlanto-axial instability. Conclusions. Bipolar halo-traction is effective for acute monofocal or multifocal injuries of the cervical spine, and for pathological course of bone regeneration after fractures of the upper cervical vertebrae.

<b><i>Introduction:</i></b> In the case of tumor resection in the upper cervical spine, a multilevel laminectomy with instrumented fixation is required to prevent kyphotic deformity and myelopathy. Nevertheless, instrumentation of the cervical spine in children under the age of 8 years is challenging due to anatomical considerations and unavailability of specific instrumentation. <b><i>Case Presentation:</i></b> We present a case of 3D-printed model-assisted cervical spine instrumentation in a 4-year-old child with post-laminectomy kyphotic decompensation of the cervical spine and spinal cord injury 1 year after medulloblastoma metastasis resection in the upper cervical spine. Due to unavailability of specific instrumentation, 3D virtual planning was used to assess and plan posterior cervical fixation. Fixation with 3.5 mm lateral mass and isthmic screws was suggested and the feasibility of fixation was confirmed “in vitro” in a 3D-printed model preoperatively to reduce the possibility of intraoperative implant-spine mismatch. Intraoperative conditions completely resembled the preoperative plan and 3.5 mm polyaxial screws were successfully used as planned. Postoperatively the child made a complete neurological recovery and 2 years after the instrumented fusion is still disease free with no signs of spinal decompensation. <b><i>Discussion/Conclusion:</i></b> Our case shows that posterior cervical fixation with the conventional screw-rod technique in a 4-year-old child is feasible, but we suggest that suitability and positioning of the chosen implants are preoperatively assessed in a printed 3D model. In addition, a printed 3D model offers the possibility to better visualize and sense spinal anatomy “in vivo,” thereby helping screw placement and reducing the chance for intraoperative complications, especially in the absence of intraoperative spinal navigation.
