The posterior rigid stabilization system and novel stabilization system do not have a significant superiority over one another. Equivalent results in the limitation of movement and rigidity allow for the use of these systems for short-segment posterior spinal instrumentation with the same indications.

Thoracolumbar burst fractures are common clinical entity encountered in neurosurgical practice, accounting for 10-20% of all spinal fractures. Clinical picture could be devastating due to severe neurological deficits which lead the patients dependent both socially and emotionally. This study compared two groups of patients who were operated because of thoracolumbar burst fracture secondary to spinal trauma in terms of neurologic deficits, degree of improvement, and radiologic measurements at one-year follow-up. The first group (group I) included the patients who underwent posterior total laminectomy, peroperative reduction of intracanal bone fragments, and posterior spinal instrumentation and the second group (group II) included the patients who underwent total laminectomy, and spinal instrumentation without reduction of free bone fragments. Neither group showed significant correlation with any measurement parameter. Radiological assessments and clinical improvements did not disclosed significant difference between the two groups at one-year follow-up. Retropulsion of free bone fragments extend the time of surgery and causes complications. This study found that there is no need to retropulse the bone fragments in the spinal canal in patients with unstable burst fractures who underwent total laminectomy and posterior long segment stabilization.

Aim: This study aimed to aimed to classiffication the morphological and pathological anatomic features of patients with coccydynia.Patients and Method: Patients over 16 years of age who were admitted to Alanya Alaaddin Keykubat University Educational Research Hospital with complaints of coccydynia between April 2015 and April 2018, were included in the study. The sitting and standing coccyx and anterior-posterior pelvic radiographs of the patients were examined retrospectively.Results: It was observed that coccyx scoliosis, hypermobility, and dislocation were unrelated to sacrococcygeal angulation. There was a positive correlation between sacrococcygeal and intercoccygeal angles in the measurements of sitting and standing coccyx radiographs of the patients. There was a correlation between the length of the sacrum and length of the coccyx and also the intercoccygeal angle and coccyx length in the unoperated patients. There was a positive correlation between length of the sacrococcygeal joint and sacrococcygeal angle in males. Fusion in the sacrococcygeal joint was less in females. Conclusion: In the evaluation of patients with coccydynia, it should not be forgotten that the coccyx is a spinal segment which can move in all planes and develop pathology. Side and AP positioned sitting and standing dynamic radiography is an effective method for the detection of pathology in this patients. New classification including pathology in all three planes is needed in the classification of patients with coccydynia. We believe that our classification will eliminate this deficit.

Cavernous malformations are characterized by enlarged vascular structures located in benign neural tissues within the cerebellum and spinal cord of the central nervous system. Cavernous hemangiomas (CHs) account for 5% to 12% of all spinal vascular malformations. We removed a hemorrhagic thoracic mass in a 40-year-old male patient who presented with progressive neurological deficits. We found it appropriate to present this case due to its rarity.
