Objective: To study the relationship between distribution of bone cement and intravertebral cleft of patients with Kummell disease on the clinical effect of percutaneous kyphoplasty (PKP).
Methods: According to the relationship between the distribution of bone cement and the cleft in the vertebrae, a total of 92 patients with Kummell disease who underwent PKP in our hospital were divided into 2 groups. Specifically, the bone cement of patients in group A was localized in the cleft of the vertebrae and did not infiltrate around the cleft, while that of group B patients not only filled the cleft of the vertebrae, but also distributed diffusely around the cleft of the vertebrae.
Objective: To describe the clinical outcomes of occipitocervical fusion (OCF) using cervical pedicle fixation with assistance of O-arm navigation and present its clinical feasibility.
Methods: From January 2015 to December 2016, eight patients with a variety of diagnoses were surgically treated with occipitocervical fusion using cervical pedicle screws under O-arm navigation. All patients received full workup consisting of clinical and radiological assessments.
Objective: To evaluate the safety and efficacy of O-arm-guided minimally invasive pedicle screw fixation combined with percutaneous kyphoplasty for metastatic spinal tumors with posterior wall destruction.
Methods: Patients who underwent minimally invasive pedicle screw fixation combined with percutaneous kyphoplasty for pathological vertebral fractures with posterior wall defects from January 2015 to December 2017 were followed up for 1 year. Visual analogue scale (VAS), SF-36 scores, middle vertebral height, posterior vertebral height, and the accuracy of pedicle screws were assessed preoperatively, postoperatively, and 1 year after surgery.
