Preventing distal pullout of posterior spine instrumentation in thoracic hyperkyphosis: a biomechanical analysis.
An in vitro biomechanical study. ⋯ Posterior dual rod constructs fixed distally using pedicle screws were stiffer and stronger in resisting forward flexion compared with cables or hooks alone. Augmenting these screws with either infralaminar hooks or sublaminar cables provided additional resistance to failure.

Anterior decompression and interbody fusion with BAK/C for cervical disc degenerative disorders.
A retrospective clinical study of 64 patients who underwent anterior cervical discectomy and fusion (ACDF) with BAK/C for disc degenerative disorders. ⋯ Although BAK/C technique was generally effective and safe in the treatment of cervical disc degenerative disorders, the pitfalls of cage design resulted in the disability of maintenance of cervical lordosis and intervertebral height in the long-term follow-up. Cage subsidence, which tended to develop in the patients with 2-level fusion, was possibly responsible for the recurrence of neck pain.

Surgical treatment of lumbar tuberculous spondylodiscitis by transforaminal lumbar interbody fusion (TLIF) and posterior instrumentation.
Retrospective case study. ⋯ Transforaminal lumbar interbody fusion with pedicle screw fixation is a simple, safe, and effective procedure for treatment of selected patients suffering from lumbar and lumbosacral tuberculosis.
