Introduction: The incidences of both car accident and sport accident have been increasing lately in Indonesia. One of the big problems is about the trauma of the spine. Cervical spine trauma is the most dangerous case. Herein we report one case of Odontoid Fracture Type II.Methods: A 24-years-old man had an accident after jumping into a shallow swimming pool. The patient bumped his head into the floor and suffered from tetraparesis. After that, he was getting better step-by-step. Approximately 3 months later, the patient bumped his head again on a branch of a tree and regressed to tetraparesis again. We established odontoid fracture type II diagnosis from plain cervical x-ray. We decided to do a surgery by using pedicle screws at CII, lateral mass at CI, and fusion at CI and CII.Result: After the surgery, the patient’s health improved. Six months after the operation, the patient recovered well.Conclusion: We can do this operation without c-arm, we performed this operation by free-hand and anatomy landmark.

Type II odontoid fracture is one of the most common cervical spine injuries, associated with significant morbidity. A thorough history and evaluation of diagnostic imaging is crucial to identify specific patient and injury factors that will assist with the treatment algorithm. The initial decision between operative and nonoperative management is made on the basis of careful consideration of the patient’s age, comorbidities, concomitant injuries, prior functional status, neurological status, and fracture morphology. This chapter describes various operative surgical treatments for odontoid fractures, including segmental fixation consisting of C1 lateral mass with either C2 pedicle or pars screws, anterior odontoid osteosynthesis, and C1–C2 transarticular screw fixation. A posterior approach with segmental fixation using C1–C2 lateral mass with C2 pars screw is reviewed with special attention to help avoid neurovascular complications. Postoperatively, patients should be monitor for signs of retropharyngeal hematoma, dysphagia, aspiration, vocal cord paralysis, and surgical site infections.

Abstract OBJECTIVE AND IMPORTANCE Posterior cervical stabilization for cervical fractures is common, and numerous techniques for fixation have been described. This case describes the novel usage of C1 laminar screws due to a persistent intersegmental artery and congenital fusion of C2–C3. CLINICAL PRESENTATION A 64-year-old woman presented with loss of consciousness after falling down a flight of stairs. Initial CT scan showed a type II odontoid fracture with significant malalignment, as well as an anomalous congenital fusion of C2–C3 and degenerative spondylolisthesis of C3 to C4. CT angiogram demonstrated bilateral persistent first intersegmental arteries coursing through the C1–C2 neural foramina. INTERVENTION The patient underwent C2 fracture reduction and posterior C1–C4 fusion. C1 posterior arch screws were placed due to the patient's anomalous vertebral artery location. The construct was anchored caudally by C2 pars interarticularis screws and C4 lateral mass screws. The patient experienced an excellent neurologic and radiographic outcome at 12.5 months. CONCLUSION Posterior fixation for fractures of the cervical spine is common; however, the use of C1 posterior arch screws for fractures has not previously been described. The presence of a persistent intersegmental course of the vertebral artery, a rare but reported anomaly, should be regarded as a contraindication to placement of C1 lateral mass screws and necessitates careful consideration of the available surgical options.

Posterior Instrumented Fusion

Abstract Nonunion of a type II odontoid fracture after the placement of an anterior odontoid screw can occur despite careful patient selection. Countervailing factors to successful fusion include the vascular watershed zone between the odontoid process and body of C2 as well as the relatively low surface area available for fusion. Patient-specific factors include osteoporosis, advanced age, and poor fracture fragment apposition. Cervical 1-2 posterior instrumented fusion is indicated for symptomatic nonunion. The technique leverages the larger posterolateral surface area for fusion and does not rely on bony growth in a watershed zone. Although loss of up to half of cervical rotation is expected after C1-2 arthrodesis, this may be better tolerated in the elderly, who may have lower physical demands than younger patients. In this video, we discuss the case of a 75-yr-old woman presenting with intractable mechanical cervicalgia 7 mo after sustaining a type II odontoid fracture and undergoing anterior odontoid screw placement at an outside institution. Cervical radiography and computed tomography exhibited haloing around the screw and nonunion across the fracture. We demonstrate C1-2 posterior instrumented fusion with Goel-Harms technique (C1 lateral mass and C2 pedicle screws), utilizing computer-assisted navigation, and modified Sonntag technique with rib strut autograft.  Posterior C1-2-instrumented fusion with rib strut autograft is an essential technique in the spine surgeon's armamentarium for the management of C1-2 instability, which can be a sequela of type II dens fracture. Detailed video demonstration has not been published to date.  Appropriate patient consent was obtained.
