Four subjects who underwent inter- body lumbar vertebra fusion surgery were excluded, and a total of 496 subjects with 496 CT scans were used for validation (301 men and 195 women; mean age, 53.7 ± 8.7 years). The external validation dataset included 600 patients who had both ...
As for the surgery, the L3 aggressive vertebral hemangioma was dealt with by performing partial resection to ensure proper decompression of the Spinal canal and using Intraoperative vertebroplasty as an adjunct treatment to prevent tumor recurrence. In addressing the deformity, choosing the Upper Instrume...
ⅱ)Position, preparation before surgery: The patient will be laid down in a face-down position. The responsible vertebral level will be confirmed under fluoroscope. ⅲ)Skin incision: A 6-8cm midline skin incision will be made at the responsible disc level. ⅳ)Separation of paravertebral muscles...
We aimed to find the incidence of revision surgery due to CASD and to analyze the factors that affected CASD at the L3-4 level after L4-5 or L4-5-S1 level fusion surgery over a long-term follow-up period.European spine journal: official publication of the European Spine Society, the ...
Effect of mono- or bisegmental spinal fusion surgery (l3 – S1) on trunk range of motion and gait performanceStudy Design: Fifty patients surgically treated for tethered cord syndrome (TCS) were retrospectively studied at Liaquat NationalHospital, Karachi from 2010 until 2014.Purpose: To assess ...
At the level of L3鈥揕4, magnetic resonance imaging (MRI) revealed an intradural, extra-axial spinal mass. This individual had several specific MRI imaging characteristics. Laminectomy, durotomy, and transforaminal lumbar interbody fusion surgery was performed, and the disc was completely removed. ...
