Background Data: Epidermoid cysts grow slowly so the symptoms would present with slowly progressive course and delay in the diagnosis that may extend up to years. 4 Presence of neurological symptoms and signs is usually detected that might be associated with local mild but persistent back pain. Purpose: To describe a case presentation of spinal epidermoid cyst. Study design: A case report of intradural thoracic an epidermoid cyst. Patients and Methods: Our case was a forty years old male patient presenting with left lower limb motor weakness. He had a 5 month history of slowly progressive left lower limb weakness and not associated with sphincter disturbance. Magnetic resonance imaging of the spine demonstrated an intradural lesion of the thoracic part of the spinal cord. Results: The lesion was excised totally and 14 days after the surgical removal, the motor power of the left lower limb showed marked improvement up to grade 4 on MRC scale. Conclusion: The diagnosis of intradural epidermoid cyst could be considered in patients with slowly progressive lower limbs weakness and mild persistent back pain. (2016ESJ121)

Background: Percutaneous pedicle screw fixation is a minimally invasive spine surgery offers patients the benefits of decreased blood loss, fewer complications, and a more rapid return to daily activity. Aim of Study:To evaluate the percutaneous fixation as regard surgical procedure in the management of unstable dorsal and lumbar spine fracture and the clinical outcome.Patients and Methods: This study included 30 patients with traumatic thoracolumbar fractures. These patients were treated by percutaneous pedicle screw fixation. This study was conducted in Cairo University Hospitals from June 2011 to February 2014. They were neurologically free.Results: This series consist of 30 patients presenting with wedge and burst fractures of thoracic and lumbar spine (D12-L4). They were treated with percutaneous fixation. These patients were assessed pre-operative and post-operative looking into following points: (A) Clinical and functional assessment; (B) Radiological assessment (C) Intraoperative post-operative complication. Conclusion:Percutaneous spine fixation is a safe technique for treatment of thoracolumbar wedge and burst fractures with no neurological affection. It has the advantage of short time surgery, no blood loss, no muscle damage. Moreover, short hospital and bed stay are important benefits of percutaneous spine fixation.

Background Data: Treatment of spinal injury aims for restoration of spinal anatomy, relieving the pain and achieving stability without neurological damage. One of the recent surgical approaches to spinal cord compression is transpedicular re-impaction of retro-pulsed vertebral body fragments and/ or partial or complete corpectomy with verebroplasty and posterior fixation. Purpose: to assess the effectiveness of the transpedicular approach in spinal decompression, reconstruction, realignment and fixation. Study design: prospective clinical case study. Patient and Methods: we report on 25 patients with traumatic dorso-lumbar fracture causing anterior neural compression. Ten patients were males and 15 were females. The mean age was 39.4±16.8 (range 17-60). Outcome measures: clinical outcome was assessed by visual analogue scale for pain and ASIA-Imsop scale for motor. Radiological outcome assessed canal compression, vertebral height and kyphotic angel. All patients had been operated posteriorly, with transpedicular decompression with and without vertebroplasty. Long segment pedicle screw fixation was done in all cases. Follow up period was 12 months. Results: Significant improvement in pain and motor state was recorded in early postoperative scales that maintained in late postoperative scale. Canal compromise, vertebral height and kyphotic angel were significantly reduced. Conclusion: Transpedicular approach is an effective technique done in familiar position. It is a safe, taking relatively short time, with minimal blood loss and with few operative complications. The procedure achieved significant ventral decompression, improved and maintained vertebral alignment. (2013ESJ048)
