Minimally invasive transforaminal interbody fusion surgery for the old fracture of the thoracolumbar junction.
Retrospective analysis of the clinical outcomes of 15 patients with the old thoracolumbar junction fracture treated by minimally invasive surgery (MIS) transforaminal interbody fusion surgery. ⋯ MIS transforaminal interbody fusion is a safe and effective procedure for old thoracolumbar junction fracture with chronic pain. Improvement of kyphosis is limited and occurrence of nonunion is relatively high.

A novel minimally invasive technique for the treatment of high-grade isthmic spondylolisthesis using a posterior transsacral rod.
Case report of 3 patients with high-grade isthmic spondylolisthesis treated using a novel minimally invasive technique using a posterior transsacral rod. ⋯ We have shown the technical feasibility of anterior and posterior fusion for severe L5-S1 spondylolisthesis using a minimally invasive percutaneous technique through a transsacral approach. The main advantage of a posterior transsacral axial rod fixation is that it creates a structurally sound anterior column support, thus eliminating the problems related to bone grafts and eliminating the complications associated with an anterior approach. Our preliminary results suggest that this technique is feasible and seems to be associated with favorable outcome, although larger studies are warranted to verify these findings.

Use of Nanocrystalline Hydroxyapatite With Autologous BMA and Local Bone in the Lumbar Spine: A Retrospective CT Analysis of Posterolateral Fusion Results.
A retrospective, multicenter, medical record review and independent analysis of computed tomographic scans was performed in 46 patients to determine radiographic arthrodesis rates after 1-segment, 2-segment, or 3-segment instrumented posterolateral fusions (PLF) using autograft, bone marrow aspirate (BMA), and a nanocrystalline hydroxyapatite bone void filler (nHA). ⋯ The arthrodesis rates after instrumented lumbar fusion using local autograft mixed with BMA and the nHA is equivalent to the rates reported for iliac crest autograft in these indications, including stringent indications, such as 3-segment procedures. By approximately 12 months postoperatively, there was no significant difference in the rates of bridging bone between the 1-segment, 2-segment, and 3-segment procedures.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivitives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

Comparative StudyRadiation exposure for fluoroscopy-guided lumbosacral epidural steroid injections: comparison of the transforaminal and caudal approaches.
A retrospective investigation. ⋯ The longer the fluoroscopy time, the greater the KAP in both transforaminal and caudal ESIs. The fluoroscopy time for transforaminal ESI was longer than that for caudal ESI. However, KAP of transforaminal ESI was less than that of the caudal ESI, after being corrected for the length of fluoroscopy time.

Anterior column realignment (ACR) for focal kyphotic spinal deformity using a lateral transpsoas approach and ALL release.
Retrospective case series. ⋯ Compared with posterior-based techniques, our preliminary results of ACR showed similar correction capacity and similar rate of morbidities for the treatment of focal kyphotic spinal deformity. Careful case selection, attention to the details of the technique, and enough experience are prudent elements for a desirable outcome.
