Posterolateral Floating Technique for the Thoracic Ossification of the Posterior Longitudinal Ligament with Navigation: A Technical Note.

We describe a floating technique via a posterolateral approach with intraoperative O-arm navigation to facilitate decompression of the spinal cord in thoracic myelopathy due to severe ossification of the posterior longitudinal ligament (OPLL). A 62-year-old man with myelopathy due to thoracic OPLL had left-leg muscle weakness, urinary disturbance, and spastic gait. Bilateral leg pain and gait disturbance had persisted for 2 years.

Comparative Analysis of Unilateral versus Bilateral Instrumentation in TLIF for Lumbar Degenerative Disorder: Single Center Large Series.

Background: Transforaminal lumbar interbody fusion (TLIF) with bilateral pedicle screw instrumentation is a well-accepted technique in lumbar degenerative disc disorder. Unilateral instrumentation in TLIF has been reported in the literature. This study aims to compare the clinical and radiological outcomes of unilateral and bilateral instrumented TLIF in a selected series of patients.

Long-Term Experience With Reduction Technique in High-Grade Spondylolisthesis in the Young.

Background: Surgical management of high-grade spondylolisthesis in the young is not only challenging but also controversial, from in-situ fusion to complete reduction. It is fraught with dangers such as neurological injury, pseudoarthrosis, and progressive deformity with subsequent global sagittal imbalance. We describe our experience of progressive reduction technique and restoration of lumbosacral alignment.
