Objective: The objective of this review is to reveal the quality of published data and the effect size of DPFs compared to rigid fixation in lumbar spine. Summary of background data: since 2002, several dynamic pedicle fixation (DPF) systems have been developed with the aim to stabilize the spine without the undesirable effects of rigid lumbar spine fixation. Nearly ten years later, there are several studies on these dynamic systems. Methods: A systematic review was done in MEDLINE/PubMED, Embase, Cochrane Central Register of Randomized Trials and Google Scholar to assess the quality of published literature and the available studied outcomes in randomized controlled trials of DPF. Results: Only three papers described randomized trials studying DPF. One of them focused on protection of adjacent level disease provided by DPF. Conclusion: It was not possible to reveal any evidence for benefits using DPF compared to rigid fixation in surgery for lumbar spine.

Cervical Spine Fixation

Fixation at the craniovertebral junction (CVJ) is necessary in a variety of pediatric clinical scenarios. Traditionally an occipital bone to cervical fusion is preformed, which requires a large amount of hardware to be placed on the occiput of a child. If a patient has previously undergone a posterior fossa decompression or requires a decompression at the time of the fusion procedure, it can be difficult to anchor a plate to the occipital bone. The authors propose a technique that can be used when faced with this difficult challenge by using the occipital condyle as a point of fixation for the construct. Adult cadaveric and a limited number of case studies have been published using occipital condyle (C-0) fixation. This work was adapted for the pediatric population. Between 2009 and 2012, 4 children underwent occipital condyle to axial or subaxial spine fixation. One patient had previously undergone posterior fossa surgery for tumor resection, and 1 required decompression at the time of operation. Two patients underwent preoperative deformity reduction using traction. One child had a Chiari malformation Type I. Each procedure was performed using polyaxial screw-rod constructs with intraoperative neuronavigation supplemented by a custom navigational drill guide. Smooth-shanked 3.5-mm polyaxial screws, ranging in length from 26 to 32 mm, were placed into the occipital condyles. All patients successfully underwent occipital condyle to cervical spine fixation. In 3 patients the construct extended from C-0 to C-2, and in 1 from C-0 to T-2. Patients with preoperative halo stabilization were placed in a cervical collar postoperatively. There were no new postoperative neurological deficits or vascular injuries. Each patient underwent postoperative CT, demonstrating excellent screw placement and evidence of solid fusion. Occipital condyle fixation is an effective option in pediatric patients requiring occipitocervical fusion for treatment of deformity and/or instability at the CVJ. The use of intraoperative neuronavigation allows for safe placement of screws into C-0, especially when faced with a challenging patient in whom fixation to the occipital bone is not possible or is less than ideal.

Oval Shape

Complex evaluation of scoliotic deformity was performed using CT. Fifty patients with displastic scoliosis of III-IV degree were examined before and after surgical intervention - dorsal correction and spine fixation with Cotrel-Dubousset instrumentation. No marked derotation of spine at the deformity apex was noted postoperatively. Changes of thorax in the plane of apical vertebra were studied and quantitatively evaluated: postoperatively thorax became of more correct oval shape in all cases. Density of trabecular bone of apical and neutral vertebrae coincided with the understanding about asymmetry of deformed vertebrae bone density. No marked immediate postoperative changes were noted. Combination of CT and myelography showed the dislocation ofdural sac to the side opposite to the deformity convexity; either partial (up to 60- 70% in patients with deformity of HI and early W degree) or complete (in patients with severe deformity) disturbance of contrast distribution in subarachnoidal space from concave side and compensatory widening of subarachnoidal space from the opposite side with maximum changes at the apex of scoliotic deformity
