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)
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)
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)
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)
INTRODUCTION It was hypothesized that multiple injections of cryopreserved bone marrow (BM) would promote fracture healing. MATERIALS AND METHODS Experiments were performed to select a method for freezing BM nucleated cells based on the recovery rate, and to investigate the effects of frozen BM nucleated cells on fracture healing in a rabbit fracture(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)
The self-healing potential of each tissue belongs to endogenous stem cells residing in the tissue; however, there are currently no reports mentioned for the isolation of human rotator cuff-derived mesenchymal stem cells (RC-MSCs) since. To isolate RC-MSCs, minced rotator cuff samples were first digested with enzymes and the single cell suspensions were(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)
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 Bone marrow-derived mesenchymal stem cells (MSCs) from humans cultured under hypoxic conditions increase bone healing capacity. HYPOTHESIS Rat MSCs cultured under hypoxic conditions increase the tendon healing potential after transplantation into injured Achilles tendons. STUDY DESIGN Controlled laboratory study.
