STUDY DESIGN A biomechanical finite element modeling study of the human lumbar spine. OBJECTIVE To evaluate the effects of a transforaminal interbody device's footprint on lumbar spine biomechanics to further examine the potential subtle biomechanical differences not captured in previous studies. SUMMARY OF BACKGROUND DATA In recent years, the evolution of interbody fusion devices has provi...

Lumbar fusion is commonly performed to alleviate chronic low back and leg pain secondary to disc degeneration, spondylolisthesis with or without concomitant lumbar spinal stenosis, or chronic lumbar instability. However, the risk of iatrogenic injury during traditional anterior, posterior, and transforaminal open fusion surgery is significant. The axial lumbar interbody fusion (AxiaLIF) system ...

A novel cortical bone trajectory (CBT) screw technique provides an alternative fixation technique for lumbar spine. Trajectory of CBT screw creates a caudo-cephalad path in sagittal plane and a medio-lateral path in axial plane, and engages cortical bone in the pedicle. The theoretical advantage is that it provides enhanced screw grip and interface strength. Midline lumbar fusion (MIDLF) is com...

BACKGROUND Minimum clinical important difference (MCID) has been adopted as the smallest improvement in patient-reported outcome needed to achieve a level of improvement thought to be meaningful to patients. OBJECTIVE To use a common MCID calculation method with a cost-utility threshold anchor to introduce the concept of minimum cost-effective difference (MCED). METHODS Forty-five patients ...

Study Design Prospective, cohort, non-inferiority study. Purpose This study evaluated the clinical and radiological outcomes of interbody fusion using a combination of demineralized bone matrix (DBM) and hydroxyapatite (HA). Overview of Literature The use of autografts remains a gold standard in lumbar interbody fusion, but the limited availability and donor site morbidity encourages the us...

Objective: To describe the presentation spectrum of postoperative spondylodiscitis (POS<i>e</i>) following transforaminal endoscopic lumbar discectomy and to report outcomes interbody fusion (TLIF).Methods: This study analyzed all patients with classic features POS<i>e</i> who underwent index surgery elsewhere presented us. They had not responded conservative care for 3 ...

Introduction: Oblique lateral lumbar interbody fusion (OLIF) and transforaminal (TLIF) are two commonly used procedures for the treatment of degenerative diseases, but efficacy is not clear. Materials Methods: PubMed, Embase, Cochrane Library databases were searched controlled studies OLIF TLIF in diseases. Include all articles published before Oct 2022. Two researchers conducted quality evalua...

Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) is performed via tubular dilators thereby preserving the integrity of the paraspinal musculature. The decreased soft tissue disruption in the MIS technique has been associated with significantly decreased blood loss, shorter length of hospitalization, and an expedited return to work while maintaining comparable arthrodesis rat...

STUDY DESIGN Retrospective case series. OBJECTIVE To describe a modified technique for mini-open transforaminal lumbar interbody fusion (TLIF) that improves visualization for decompression, fusion, and freehand pedicle screw insertion. Accuracy of freehand pedicle screw placement with this technique was assessed. SUMMARY OF BACKGROUND DATA Mini-open TLIF is a minimally invasive technique th...
