BACKGROUND The anteriorly displaced type II odontoid fracture is treated either conservatively by halo-vest brace immobilization or surgically by posterior atlantoaxial fusion. Anterior odontoid screw fixation is not advised for this pattern of odontoid fracture because of the difficult trajectory for screw insertion despite its advantage of salvaging the upper cervical spine rotatory range of ...

A 10-year-old boy presented with torticollis and neck pain for 2 months without fever. His physical examination showed torticollis and limitation of flexion/extension and cervical rotation without neurological deficit. Family and past histories were unremarkable. Cervical spine radiographs showed a cervical scoliosis with loss of the normal cervical lordosis and partial collapse of C3 vertebral...

BACKGROUND Intermuscular approaches can expose the lumbar spine and minimize muscular trauma and injury. The segmental anatomy of the posterior lumbar musculature allows surgical access through separation of muscle groups and fascicles and provides one to develop intermuscular working channels while preserving the integrity of the muscles and their function. In addition, preservation of the acc...

We present seven children with atlantoaxial rotatory fixation (AARF) of more than three months' duration after an injury to the upper cervical spine. The deformity was irreducible by skull traction. MRI and MR angiography (MRA) of the vertebral arteries were performed in four children. The patients were neurologically intact. Thrombosis of the ipsilateral vertebral artery was noted in two patie...

BACKGROUND Even though internal fixation has expanded the indications for cervical spine surgery, it carries the risks of fracture or migration, with associated potential life threatening complications. Removal of metal work from the cervical spine is required in case of failure of internal fixation, but it can become challenging, especially when a great amount of scar tissue is present because...

When ossification of the yellow ligament (OYL) occurs in the lumbar spine and extends to the lateral wall of the spinal canal, facetectomy is required to remove all of the ossified lesion and achieve decompression. Subsequent posterior fixation with interbody fusion will then be necessary to prevent postoperative progression of the ossification and intervertebral instability. The technique of l...

RATIONALE Surgical site infection (SSI) following spine surgeries involving internal fixation often require removing the instrument; however, this can cause spinal instability. Previous reports have demonstrated the usefulness of vacuum sealing drainage (VSD) therapy, but the cases require wound opening, aseptic condition to replace the VSD device, and a secondary operation to close the wound. ...

With today’s aging population, musculoskeletal diseases such as osteoporosis, degenerative arthritis, and degenerative spine disease, are on the rise, and these conditions are associated with increased fracture risk. Intertrochanteric fractures in elderly patients often involve severe displacement or comminution with poor bone quality. Accordingly, various treatment methods for hip fracture hav...

BACKGROUND Skeletal and soft tissue damage are often associated with unilateral facet dislocations, which undoubtedly lead to instability of the spine and further increase difficulties in cervical reduction. This type of irreducible facet dislocation is usually accompanied with potential catastrophic consequences including neurological deficit and severe disability. Therefore, a consistent and ...

Clavicle fractures are common in adults. Recent studies have shown that operative treatment of clavicle fractures has benefits in many situations. However, there is controversy about the indications. Data on social outcomes are limited. A total of 434 patients with 436 clavicle fractures treated both operatively and nonoperatively at a level 1 trauma center were identified. Narcotic use was rec...
