Clinical TrialUnipedicular balloon kyphoplasty for the treatment of osteoporotic vertebral compression fractures: early results.
The traditional bipedicular kyphoplasty was proved to be safe and effective for the treatment of pain associated with osteoporotic vertebral compression fractures (VCFs). Nevertheless, unilateral kyphoplasty would be an attractive alternative to the traditional bipedicular kyphoplasty owing to theoretical speed, safety, and less expense; thus far, the biomechanical testing showed that experimental unilateral kyphoplasty had properties comparable with bipedicular kyphoplasty. To date, no clinical data are available regarding the efficacy and safety of unilateral balloon kyphoplasty. In this prospective observational study, the clinical and radiographic outcomes of the unipedicular (unilateral) balloon kyphoplasty in osteoporotic VCFs are evaluated. ⋯ Unipedicular (unilateral) extrapedicular kyphoplasty is both a safe and efficacious alternative to the traditional bipedicular kyphoplasty for the treatment of painful osteoporotic VCFs. As a technique, it is faster, less expensive, and involves less radiation exposure for the surgical suite personnel.

Correction of apical axial rotation with pedicular screws in neuromuscular scoliosis.
A retrospective study to measure the postoperative apical axial derotation with posterior pedicle screw fixation in neuromuscular scoliosis. ⋯ Our results indicate that apical axial derotation can be well achieved with posterior only pedicle screw fixation in patients with neuromuscular scoliosis without any need for an anterior release procedure.

Feasibility of occipital condyle screw placement for occipitocervical fixation: a cadaveric study and description of a novel technique.
Occipital-cervical (OC) stabilization using occipital condyle fixation with a polyaxial screw-rod construct is described. ⋯ Condyle screws can be placed without injury to neurovascular structures. OC junction fixation using polyaxial occipital condyle screws is feasible and can be considered a salvage technique or an alternative where other fixation techniques are not available.

Instrumented slip reduction and fusion for painful unstable isthmic spondylolisthesis in adults.
Although in situ posterolateral fusion is considered the gold standard for surgical treatment of low-grade adult spondylolisthesis, correction of the sagittal translation by instrumented slip reduction is more controversial in adults; nevertheless it may delay adjacent level disc degeneration. ⋯ Our results may support performing slip reduction in selected adults with isthmic spondylolisthesis.
