After spinal cord injury (SCI), the absence of an adequate blood supply to injured tissues has been hypothesized to contribute to the lack of regeneration. In this study, blood vessel changes were examined in 28 adult female Fischer 344 rats at 1, 3, 7, 14, 28, and 60 days after a 12.5 g x cm NYU impactor injury at the T9 vertebral level. Laminin, collagen(More)
STUDY DESIGN A retrospective review. OBJECTIVE To characterize the risk factors for the development of major complications in 3-column osteotomies and determine whether the presence of a major complication affects ultimate clinical outcomes. SUMMARY OF BACKGROUND DATA Three-column spinal osteotomies, including pedicle subtraction osteotomy (PSO) and(More)
STUDY DESIGN Retrospective clinicoradiographic analysis. OBJECTIVE To compare the upper thoracic (UT) and lower thoracic (LT) spines as the upper instrumented vertebra in primary fusions to the sacrum for adult scoliosis. SUMMARY OF BACKGROUND DATA The optimal level at which a fusion to the sacrum is terminated proximally for adult scoliosis remains(More)
STUDY DESIGN Retrospective radiographic and clinical study. OBJECTIVE To examine the long-term outcome of selective thoracic fusion (STF) performed for lumbar "C" modifier curves in adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA The efficacy of STF in lumbar "C" false double major curves is controversial. We examined the 5- to 24-year(More)
Femoral component revisions with extensively coated stems have shown promising clinical results, although concerns over stress shielding still exist. We retrospectively reviewed 59 patients undergoing femoral component revision with an extensively hydroxyapatite (HA)-coated stem. The average length of follow-up was 3.3 years (range, 2-5 years). The average(More)
Bicondylar tibial plateau fractures can be difficult to treat due to the extent of articular cartilage, metaphyseal bone, and soft tissue injury. The purpose of this study was to compare the outcomes of open reduction and locked plating vs fine-wire external fixation of 58 consecutive bicondylar tibial plateau fractures at a level I trauma center. All(More)
STUDY DESIGN Retrospective review. OBJECTIVE To determine the incremental cost-effectiveness of cell saver for single-level posterior lumbar decompression and fusion (PLDF). SUMMARY OF BACKGROUND DATA Intraoperative cell salvage is used during surgery to reduce the need for perioperative allogeneic blood transfusion. Although the use of cell saver may(More)
STUDY DESIGN Longitudinal cohort. OBJECTIVE To establish minimum clinically important difference (MCID) threshold values for Scoliosis Research Society-22R (SRS-22R) domains in patients with adult spinal deformity undergoing surgical correction. SUMMARY OF BACKGROUND DATA The SRS-22R has been shown to be reliable, valid and responsive to change in(More)
BACKGROUND Ossification of the anterior longitudinal ligament and the anulus adjacent to an anterior cervical arthrodesis has been termed adjacent-level ossification development. Initial studies suggested an association with the placement of plates <5 mm from an adjacent disc space. A follow-up study demonstrated that this ossification rarely occurs in(More)
STUDY DESIGN Multicenter retrospective analysis of prospectively collected data. OBJECTIVE Evaluate radiographical and clinical characteristics of patients undergoing a selective thoracic fusion (STF) for Lenke 1C curves. SUMMARY OF BACKGROUND DATA STF of adolescent idiopathic scoliosis has been advocated for the so-called "false double major" curve(More)
