STUDY DESIGN A prospective clinical trial was conducted. OBJECTIVES To compare the results of fusion versus nonfusion for surgically treated burst fractures of the thoracolumbar and lumbar spine. SUMMARY OF BACKGROUND DATA The operative results of surgically treated burst fractures with short segmental fixation have been well documented. There is no(More)
Bone marrow mesenchymal stem cells (MSCs) have the capacity for renewal and the potential to differentiate into multiple lineages of mesenchymal tissues. In the laboratory, MSCs have the tendency to adhere to culture dish plastic and are characterized by fibroblastic morphology, but possess no specific markers to select them. To isolate and purify MSCs from(More)
PURPOSE The purpose of this study was to compare the clinical and imaging outcomes of single-row and double-row suture anchor fixation in arthroscopic rotator cuff repair with emphasis on analysis of the effect of various tear size on repair integrity. METHODS Fifty-three patents were randomized to either single-row or double-row rotator cuff repair at(More)
OBJECTIVES To evaluate the therapeutic effect of extracorporeal shock wave therapy (ESWT) in shoulders with chronic calcific tendinitis, to compare the functional outcomes of ESWT and transcutaneous electric nerve stimulation (TENS) therapy, and to investigate which types of calcium deposit effectively respond to ESWT. DESIGN Randomized controlled trial.(More)
Size-sieved stem (SS) cells isolated from human bone marrow and propagated in vitro are a population of cells with consistent marker typing, and can form bone, fat, and cartilage. In this experiment, we demonstrated that SS cells could be induced to differentiate into neural cells under experimental cell culture conditions. Five hours after exposure to(More)
BACKGROUND Osteoarthritis and osteoporosis are the two most common musculoskeletal diseases found in the aged population. It is of interest to measure and study the material properties of the femoral head and neck of these two groups, and hopefully to offer explanation of the observed phenomenon that most patients suffer from one of the two disorders, not(More)
Mesenchymal stem cells (MSCs) have the capacity for self-renewal and can form bone, fat, and cartilage. Alginate forms a viscous solution when dissolved in 0.9% saline and gels on contact with divalent cations. The viability and phenotype maintenance of chondrocytes in alginate beads have been well documented. However, little is known about the effect of(More)
STUDY DESIGN A single-institution, single-surgeon retrospective review. OBJECTIVE To evaluate the clinical results of long posterior instrumentation with short posterior or posterolateral fusion for pyogenic spondylodiscitis of the thoracic and lumbar spine retrospectively. SUMMARY OF BACKGROUND DATA There are controversies concerning the optimal(More)
Bone marrow-derived human mesenchymal stem cells (hMSCs) give rise to adipocytes in response to a medium containing dexamethasone, isobutylmethylxanthine, and insulin. A cDNA microarray was applied to analyze the gene expression profiles between the cells at day 0 and at day 3 of incubation in the adipogenic medium, when the cells began to express(More)
BACKGROUND Shoulder joint laxity over anteroinferior and posteroinferior labral–capsular structure inpatients with traumatic anterior glenohumeral instability was reported in the previous literature. The purpose of this study was to report our experience in arthroscopic treatment of traumatic anterior–inferior shoulder instability by Bankart lesion(More)
