Minimally invasive lateral approaches for the treatment of spinal tumors: single-position surgery without the "flip".

Although primary tumors of the spine and neural elements are rare, metastatic disease to the spine is quite common. Traditionally, surgical treatment for spinal tumor patients involves open decompression with or without stabilization. The single-position minimally invasive (MIS) lateral approach, which has been recently described over the recent decade, allows simultaneous access to the anterior and posterior columns with the patient positioned in the lateral decubitus position.

Biomechanical Evaluation of a Novel Autogenous Bone Interbody Fusion Cage for Posterior Lumbar Interbody Fusion in a Cadaveric Model.

Study Design: A human cadaveric biomechanical study of a novel, prefabricated autogenous bone interbody fusion (ABIF) cage.

Objective: To evaluate the biomechanical properties of the ABIF cage in a single-level construct with and without transpedicular screw and rod fixation.

Summary Of Background Data: In current practice, posterior lumbar interbody fusion is generally carried out using synthetic interbody spacers or corticocancellous iliac crest bone graft (ICBG) in combination with posterior instrumentation.

A comparison of perioperative charges and outcome between open and mini-open approaches for anterior lumbar discectomy and fusion.

The objectives of this study were to examine charge data and long-term outcomes of two approaches for anterior lumbar interbody fusion: a mini-open lateral approach (extreme lateral interbody fusion, XLIF) and an open anterior approach (anterior lumbar interbody fusion, ALIF) through retrospective chart review. A total of 202 patients underwent surgery: 87 with ALIF (Open) and 115 with XLIF (Mini-open) procedures, all with transpedicular fixation. Complications occurred in 16.

Minimally invasive lateral extracavitary resection of foraminal neurofibromas.

Nerve sheath tumors are the most common spinal tumors but extradural foraminal nerve sheath tumors are much rarer. Traditionally, these nerve sheath tumors have been resected via an open posterior approach. We describe an alternative minimally invasive (MIS) lateral extracavitary approach for resection of symptomatic extradural foraminal spinal neurofibromas.
