Comparative StudyPolymethylmethacrylate augmentation of cannulated pedicle screws for fixation in osteoporotic spines and comparison of its clinical results and biomechanical characteristics with the needle injection method.
This is a retrospective study carried out to evaluate the clinical results of patients with osteoporosis and various spinal diseases treated surgically with polymethylmethacrylate (PMMA)-augmented cannulated pedicle screws, and to compare this method with the needle injection technique in terms of the clinical results and fixation strength. ⋯ The technique of cannulated pedicle screws with PMMA augmentation used in this study can be an option for osteoporotic patients with various spinal diseases who require spinal instrumentation.

Preliminary results on feasibility of outpatient instrumented transforaminal lumbar interbody fusion.
A retrospective chart review study was performed. ⋯ Although further confirmation is needed, this study discusses the possibility of performing instrumented lumbar interbody fusions with the transforaminal lumbar interbody fusion technique as an outpatient procedure. These results support a future prospective randomized study with a well-defined patient selection criteria.

Comparative StudyA comparative study between thoracoscopic surgery and posterior surgery using all-pedicle-screw constructs in the treatment of adolescent idiopathic scoliosis.
A retrospective comparative study. ⋯ Despite its advantages, thoracoscopic surgery is losing its place in the surgical correction of AIS because of the frequent perioperative pulmonary complications and fixation problems compared with posterior pedicle screw fixation. Nevertheless, it can be utilized in selected cases particularly in cases of patient's strong demand for minimally invasive surgery.

Convex short segment instrumentation and hemi-chevron osteotomies for Putti type 1 thoracic hemivertebrae: a simple treatment option for patients under 5 years old.
A case series depicting the results of a novel surgical technique. ⋯ Transpedicular instrumentation is ideal for early correction in young children. The new posterior approach is much less invasive than the combined approaches or other posterior vertebrectomies and is well tolerated even in very young patients. The fusion segment is kept short. The deformities seem to stop progressing and this can avoid development of severe local deformities and secondary curves.

Intraoperative 3-dimensional navigation and ultrasonography during posterior decompression with instrumented fusion for ossification of the posterior longitudinal ligament in the thoracic spine.
A retrospective clinical study was conducted. ⋯ Intraoperative ultrasonography and ITN are safe and reliable imaging methods for posterior decompression and instrumented fusion for thoracic myelopathy caused by OPLL.
