We report on a case of a patient who underwent minimally invasive transforaminal lumbar interbody fusion (mi-TLIF) with objective physical activity measurements performed preoperatively and postoperatively at up to 12-months using wireless accelerometer technology. In the first postoperative month following surgery, the patient had reduced mobility, taking 2,397 steps over a distance of 1.8 km ...

PURPOSE Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is increasingly popular for the surgical treatment of degenerative lumbar disc diseases. The constructs intended for segmental stability are varied in MI-TLIF. We adopted finite element (FE) analysis to compare the stability after different construct fixations using interbody cage with posterior pedicle screw-rod or ped...

Study Design Retrospective comparative cohort. Objective Pseudarthrosis following fusion for degenerative lumbar spine pathologies remains a substantial problem. Current data shows that patients who develop a pseudarthrosis have suboptimal outcomes. This study evaluates if treatment of pseudarthrosis can be affected by surgical approach. Methods Medical records of 63 female and 65 male patients...

INTRODUCTION Previous studies have confirmed the benefits and limitations of the presacral retroperitoneal approach for L5-S1 interbody fusion. The purpose of this study was to determine the safety and effectiveness of the minimally invasive axial lumbar interbody approach (AxiaLIF) for L4-S1 fusion. METHODS In this retrospective series, 52 patients from four clinical sites underwent L4-S1 in...

We describe the case of a woman with a history of active tabagism and on the oral contraceptive Yasmin, presenting in the Post-Anesthesia Care Unit (PACU) with a cardiac arrest due to massive pulmonary embolism following transforaminal lumbar interbody fusion surgery. The patient had preoperatively several risk factors for deep venous thrombosis. This case-report emphasizes the value of a preop...

Bone morphogenetic protein use in spinal surgery for off-label indications continues to remain popular. One area where its use has known associated radicular complications is posterior or transforaminal lumbar interbody fusion. These complications include radiculitis, cyst development, and heterotopic ossification, amongst others. Typically, cyst development has been treated surgically. We pres...
