BACKGROUND: Minimally invasive spine (MIS) surgery utilizing tubular retractors has become an increasingly popular approach for decompression in the lumbar spine. However, a better understanding of appropriate indications, efficacious surgical techniques, limitations, and complication management is required to effectively teach the procedure and to facilitate the learning curve. OBJECTIVE: To describe our experience and recommendations regarding tubular surgery for lumbar disc herniations, foraminal compression with unilateral radiculopathy, lumbar spinal stenosis, synovial cysts, and dural repair...

OBJECTIVE: Since its introduction and FDA approval, rhBMP-2 has been adopted by spine surgeons as a substitute for ICBG in numerous spinal fusion techniques. As broad clinical use increased, reports on potential complications associated with rhBMP-2 also increased. We provide our experience with TLIF using rhBMP-2 or ICBG in an entirely Hispanic population. METHODS: This was a 2-year retrospective study of 67 patients, with 26 in the rhBMP-2 group and 41 in the ICBG group, who underwent TLIF...

Although spondylolisthesis was traditionally treated with posterior lumbar interbody fusion (PLIF), minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) was recently proposed as an alternative treatment for spondylolisthesis. However, no studies have focused on the comparison of these 2 techniques' outcome on spondylolisthesis.The operative reports and perioperative data of patients who underwent single-level primary open PLIF (n = 29) and MIS-TLIF (n = 26) for I/II spondylolisthesis were retrospectively evaluated...

STUDY DESIGN: Multi-center retrospective study. OBJECTIVE: To validate and improve the predictive model for proximal junctional failure (PJF) with or without the bone mineral density (BMD) score. SUMMARY OF BACKGROUND DATA: PJF is a serious complication of surgery for adult spinal deformity (ADS). A predictive model for PJF was recently reported that has good accuracy, but does not include BMD, a known PJF risk factor, as a variable. METHODS: We included 145 surgically treated ASD patients who were older than 50 at the time of surgery and had been followed up for at least 2 years...

BACKGROUNDS: A variety of improved surgical methods were adopted in the transforaminal lumbar interbody fusion. A mechanical stability provides an ideal environment for the formation of a fusion mass and is the basis of their good outcomes. The object of this study is to evaluate the initial similarities and differences of four commonly-used posterior surgical procedures biomechanically. METHODS: Biomechanical testing was performed at L3-4 motion segment in 6 fresh-frozen human cadaveric lumbar spines (L2-L5), including the following sequentially tested configurations: 1) intact motion segment; 2) bilateral pedicle screw fixation; 3) unilateral pedicle screw fixation; 4) unilateral pedicle screw plus contralateral translaminar facet joint screw fixation according to the Magerl technique; and 5) bilateral pedicle screw fixation with bilateral facetectomies...

STUDY DESIGN: Cost-effectiveness analysis. OBJECTIVE: To evaluate the cost-effectiveness of intradiscal electrothermal therapy (IDET) relative to circumferential lumbar fusion with femoral ring allograft (FRA) in UK. SUMMARY OF BACKGROUND DATA: Circumferential lumbar fusion is an established treatment for discogenic low back pain. However, IDET could be a cost-effective treatment alternative as it can be carried out as a day case. METHODS: Patient-level data were available for patients with discogenic low back pain treated with FRA (n=37) in a randomized trial of FRA vs titanium cage, and for patients recruited to a separate study evaluating the use of IDET (n=85)...
