BACKGROUND Expandable screws have greater pullout strength than conventional screws. The purpose of this study was to compare the biomechanical stability provided by a new built-in expandable anterior spinal fixation system with that of 2 commonly used anterior fixation systems, the Z-Plate and the Kaneda, in a porcine partial vertebral corpectomy model. METHODS Eighteen porcine thoracolumbar...
OBJECTIVE The purpose of this study was to compare rod fracture (RF) rates among three types constructs (RCs) following lumbar pedicle subtraction osteotomy (PSO) for adult spinal deformity (ASD). METHODS A retrospective review consecutive patients with who were treated PSO between 2007 and 2017 performed. minimum follow-up 2 years. Three RCs compared: standard (2 main rods), satellite rods rod...
condylar dislocation is not an uncommon condition and occurs when the condyles are displaced anterior to the articular eminence and are unable to reduce back into the glenoid fossa. long-standing dislocations are difficult to treat with the conservative methods and usually need surgical intervention. in this paper, a long-standing dislocation treated by bilateral extra-oral ramus osteotomy is d...
AIM To investigate risk factors for surgical site infection (SSI) after three-column osteotomy (3CO) for spinal deformity. MATERIAL AND METHODS The American College of Surgeons National Surgical Quality Improvement Program database (2012 - 2014) was reviewed. We included adult patients who underwent 3CO and compared pertinent cases (SSI) to controls (no SSI) in terms of preoperative and opera...
STUDY DESIGN Retrospective study. PURPOSE To determine if posterior surgery alone can satisfactorily treat post-traumatic kyphosis (PTK). OVERVIEW OF LITERATURE One of the worst complications of vertebral fractures is PTK. The type of surgery and approach to treat a symptomatic and refractory PTK is a challenging issue in spinal surgery, and yet, there is no specific treatment algorithm. ...
The correction of rigid spinal deformities in adult patients can require a three-column osteotomy (pedicle subtraction osteotomy [PSO] or vertebral column resection [VCR]) to obtain spinal balance. Unfortunately, the existing adult deformity literature frequently reports the outcomes and complications of these procedures together even though VCR is a more extensive procedure with potentially hi...
Introduction. Spinal scoliosis and kyphosis in elderly people sometimes cause severe low back pain. Surgical methods such as osteotomy are useful for correcting the deformity. However, complications during and after surgery are associated with the osteotomy procedure. In particular, it is difficult to manage deformity correction surgery for patients with Parkinson's disease. Here, we present tw...
STUDY DESIGN A retrospective study. PURPOSE To clarify the differences among the three major surgeries for osteoporotic vertebral fractures based on the clinical and radiological results. OVERVIEW OF LITERATURE Minimally invasive surgery like balloon kyphoplasty has been used to treat osteoporotic vertebral fractures, but major surgery is necessary for severely impaired patients. However, t...
