STUDY DESIGN Biomechanical study using human cadaver spines. OBJECTIVE To assess the stabilizing effect of a supplemental anterior tension band (ATB, Synthes) plate on L5-S1 anterior lumbar interbody fusion (ALIF) using a femoral ring allograft (FRA) under physiologic compressive preloads, and to compare the results with the stability achieved using FRA(More)
Spinal fusion as a treatment for degenerative disc disease is controversial. Prior authors have identified various MRI findings as being pain generators, which might help guide patient selection for lumbar fusion procedures. These findings have included disc desiccation, disc contour, high-intensity zone annular disruption, the presence of Modic endplate(More)
BACKGROUND CONTEXT Acinic cell carcinoma is the fourth most common tumor of the parotid gland, and spinal metastases are thought to be exceedingly rare. Only two other reported presentations are found in the literature, both presumably secondary to incomplete surgical resections. PURPOSE To present the first known case of metastasis to the lumbar spine(More)
Clinicians use descriptive classification systems when treating patients with low back pain as an adjunct to surgical decision making. Magnetic resonance imaging (MRI) changes, including Modic changes, the presence of a high-intensity zone, and internal disk desiccation, are commonly used descriptors. The question remains whether different clinicians(More)
