It is a well-know fact that type 2 odontoid fractures frequently go into nonunion. If left untreated, patients may develop irreducible atlantoaxial dislocation (AAD). We describe the surgical management of two patients with neglected odontoid fractures and irreducible AAD treated with single stage anterior release followed by posterior instrumented fusion. Both patients presented with history of neglected trauma and progressive myelopathy. Traction under anesthesia failed to achieve reduction of AAD. Anterior release was done by trans-oral approach in one patient and retrophayngeal approach in the other. Posterior fixation was performed with transarticular screws in both the patients. Both patients had full neurological recovery and demonstrated fusion at follow-up. Anterior release followed by posterior instrumented correction may be an effective alternative to the traditional means of treating irreducible dislocations associated with neglected odontoid fractures.

Developmental anomalies of the axis are commonly encountered, especially anomalies involving the odontoid process. Anomalies of the posterior elements are uncommon. We describe a unique case of agenesis of posterior elements of C2 with basilar invagination and atlanto-axial dislocation. An obese 8-year-old boy presented with symptoms of cervical myelopathy. Radiological workup revealed a craniovertebral junction anomaly with occipitalised atlas, absent posterior elements of axis, and hypertrophied C3 spinous process. Atlanto-axial instability and basilar invagination was present. Magnetic resonance angiography revealed hypoplastic left vertebral artery. Traction with cervical tongs failed to improve the alignment and symptoms. Anterior trans-oral release, followed by posterior decompression and custom-made instrumentation, was done. The patient recovered completely and was asymptomatic at the end of two years. X-ray and computed tomography scan demonstrated reduction of basilar invagination and maintenance of alignment. This is the first case to be reported of agenesis of posterior elements of axis associated with basilar invagination. One should look for this condition in patients with hypertrophied spinous process of C3. Utilization of hypoplastic pedicle of axis serves as an additional fixation point to increase the stability of the construct.

STUDY DESIGN: Retrospective case series. PURPOSE: To describe a novel single incision that combines anterior and posterior approaches for decompression and instrumented fusion to treat tuberculosis of the thoracic spine and study the neurological and radiological outcomes. OVERVIEW OF LITERATURE: Tuberculosis of the spine remains a major health issue in many developing countries. The options for treating tuberculosis of the thoracic spine include the anterior, posterior, and combined approaches, each with its advantages and disadvantages. METHODS: Totally, 143 patients with tuberculosis of the thoracic spine were surgically treated using the “Versatile approach”. Posterior fixation was performed using sublaminar wires and a Hartshill rectangle in all patients. Anterior reconstruction was accomplished using bone graft harvested from autologous rib, iliac crest, or fibula. RESULTS: The study included 45 males and 98 females, with a mean age of 33.18±18.65 years (range, 3–82 years) and a mean follow-up of 60.23±24.56 months (range, 18–156 months). Kyphosis improved from a mean value of 24.02 preoperatively to 10.25 postoperatively. A preoperative neurological deficit was observed in 131 patients, with 130 patients regaining ambulatory power. No patient had deterioration of neurological status following surgery. Fusion was achieved in all cases. The visual analogscale score improved from an average score of 7.02 preoperatively to 1.51 at final follow-up. Eight patients had superficial macerations, which healed spontaneously. One patient had buckling of the anterior graft, and one patient had implant breakage following road traffic accident. CONCLUSIONS: The “Versatile approach” is an effective, single-stage, single-incision method that combines anterior and posterior approaches for the surgically treating tuberculosis of the thoracic spine. It offers the advantage of direct visualization for decompression and reconstruction of the anterior and posterior vertebral columns, thus providing an excellent, long-lasting clinical outcome.

STUDY DESIGN: Retrospective case series. PURPOSE: Describe the technique and evaluate the outcome of apical vertebral column resection (VCR) with sagittal rotation and anterior opening and posterior closing (AOPC) maneuver for correction of severe post-tubercular kyphosis (PTK). OVERVIEW OF LITERATURE: The surgical procedures described for the correction of PTK are VCR, pedicle subtraction osteotomy, transpedicular decancellation osteotomy, and closing-opening osteotomy. METHODS: We retrospectively evaluated 21 patients who had been operated on with single stage apical VCR with AOPC maneuver. Radiographs were obtained before surgery and at regular follow-up intervals. These were used to calculate the angle of kyphosis. Back pain was rated using the Visual Analog Scale (VAS) and neurological status was graded using Frankel grading. Radiological outcome was assessed by the improvement in the angle of kyphosis and fusion following surgery. Neurological status was assessed using Frankel grading. RESULTS: The study included eight males and 13 females with a mean age of 21.9 and average follow-up time of 30.4 months. The average number of vertebral bodies destroyed was 2.57. Kyphosis was improved from a mean of 68.42°±13.23° preoperative to 8.71°±4.58° postoperative. The average correction achieved was 87.10%. Preoperative VAS score improved from a mean of 6.38±0.92 preoperative to 1.38±0.49 postoperative. No patients had any sign of neurological deterioration. Seven out of eight patients with a preoperative neurological deficit improved following surgery. Two patients developed superficial wound maceration, one had persistent postoperative hypotension, and the other developed hemothorax. All patients recovered fully without a need for additional surgery. CONCLUSIONS: Single stage simultaneous anterior column lengthening and posterior column shortening is an effective method for surgical correction of severe PTK.
