STUDY DESIGN A retrospective clinical cohort study at a single spine center of patients with degenerative scoliosis and radiculopathy severe enough to require surgery. OBJECTIVE To evaluate the functional outcomes of 3 surgeries for degenerative scoliosis with radiculopathy; decompression alone, decompression and limited fusion, and decompression and full(More)
STUDY DESIGN A prospective, nonblinded, multicenter study of outcomes in patients undergoing single-level anterior lumbar discectomy and interbody fusion with InFUSE Bone Graft. OBJECTIVE To determine the safety and effectiveness of InFUSE Bone Graft applied to an absorbable collagen sponge in anterior lumbar interbody fusion with threaded cortical(More)
STUDY DESIGN This study prospectively evaluated the health related quality of life (HRQOL) of 73 adults presenting with scoliosis at a single institution, as related to their spinal (C7 plumbline) and global (gravity line) balance. OBJECTIVE To assess the influence of sagittal and coronal balance on HRQOL in adult scoliosis. SUMMARY OF BACKGROUND DATA(More)
OBJECTIVE Vacuum-assisted wound closure (VAC) exposes the wound bed to negative pressure, resulting in removal of edema fluid, improvement of blood supply, and stimulation of cellular proliferation of reparative granulation tissue. It has been used to treat open wounds in the extremities, open sternal wounds, pressure ulcers, and abdominal wall wounds. This(More)
Abundant data are available for direct anterior/posterior spine fusion (APF) and some for transforaminal lumbar interbody fusion (TLIF), but only few studies from one institution compares the two techniques. One-hundred and thirty-three patients were retrospectively analyzed, 68 having APF and 65 having TLIF. All patients had symptomatic disc degeneration(More)
Double-level noncontiguous spinal injury is a more common occurrence than generally appreciated. A large number of these patients have neurological injury. Because these injuries occur in patients who meet the criteria for categorization as multiple trauma patients, we feel that a complete radiographic survey of the spine must be accomplished in the(More)
BACKGROUND Anterior interbody fusion has previously been demonstrated to increase neuroforaminal height in a cadaveric model using cages. No prior study has prospectively assessed the relative change in magnetic resonance imaging (MRI) demonstrated neuroforaminal dimensions at the index and supradjacent levels, after anterior interbody fusion with a(More)
The effectiveness of Cotrel-Dubousset (CD) instrumentation in long fusions to the sacrum for adult spinal deformity was evaluated in 27 consecutive patients. The CD system provided acceptable correction of kyphosis and scoliosis while restoring or maintaining lumbar lordosis. However, the standard CD pelvic fixation using sacral pedicle and alar screws was(More)
Long levels of spinal instrumentation and fusion are common in surgery for spinal deformity. The effect on the remaining mobile segments is not well understood. The changes in lumbar facet loading and lumbosacral motion were evaluated as the number of immobilized levels increased. Four fresh canine cadaveric spines from T6 to sacrum were used. Lumbosacral(More)
STUDY DESIGN A population-based case-control study, we identified adolescents with and without scoliosis in Minnesota who were 12 through 18 years of age. Matched control subjects were randomly selected from school children who did not have scoliosis or any other condition. Information on scoliosis was obtained by a self-administered questionnaire, the(More)
