A combined open and percutaneous operative technique has been devised for repair of tendo Achillis. This minimises postoperative scarring. We compared the long-term results 12 patients treated by this method with 10 who had undergone an repair. The gave significantly better relief symptoms during everyday activities (p < 0.05), single-limb hopping 0.02) a greater chance returning to sport 0.01). There were no significant differences between two treatments as regards active range ankle...
Abstract The bone morphogenetic protein (BMP) family consists of a large number members and has diverse biological activities during development. Various tissues express pleural BMP members, which seem to cooperatively regulate developmental events. Here, multiple signals were inactivated in chondrocytes clarify the function BMPs skeletogenesis. To obtain tissue-specific inactivation, Noggin gene (Nog) was overexpressed cartilage under control α2(XI) collagen (Col11a2) promoter/enhancer...
Direct repair of a defect in the pars interarticularis was performed with use bone-grafting and internal fixation pedicle screw, rod, laminar hook order to achieve higher prevalence osseous union than that achieved commonly used procedures. The configuration head which is designed allow it connect rod at necessary angle, simplified placement rod. procedure sixteen patients who had bilateral or without grade-I II spondylolisthesis, failure non-operative treatment, temporary relief pain after...
Background: Opening-wedge high tibial osteotomy by hemicallotasis for osteoarthritis in the medial compartment of knee requires external fixation a long time, until callus maturation is complete. The aim this study was to determine if low-intensity pulsed ultrasound would accelerate when applied after distraction limbs treated with opening-wedge hemicallotasis. Methods: Twenty-one patients symmetric grades and similar degrees varus deformity two knees underwent bilateral one-stage After...
The systemic arterial pressure has been used as a guide for determining the susceptibility to surgical bleeding during controlled hypotensive anaesthesia. Arterial hypotension is not, however, necessarily accompanied by venous or intraosseous hypotension. main source of posterior spinal surgery bone and rather than arterial. intraoperative blood loss, (IOP) within first thoracic vertebral body, were measured in 27 patients cervical laminoplasty spondylotic myelopathy. loss correlated...
This study consisted of a comparison intraoperative blood loss during posterior spins surgery under normotensive general anesthesia with and without epidural blockade, hemodynamic after injection.To determine the effect blockade in reducing intraosseous pressure vertebral body.Epidural is effective surgical bleeding. has been thought to be due systemic arterial hypotension. There was no report on its venous or pressure.In achieved by preincisional caudal injection 20 ml 0.25% bupivacaine...
In posterior decompression for lumbar spinal stenosis, preservation of the elements appears to provide patients with long-term favorable outcomes. To confirm this assumption, we evaluated impact spinous process integrity, i.e., osseous continuity between and lamina, on short outcomes.As a model study retrospectively reviewed cases forty-eight who underwent open-door laminoplasty using process-splitting approach without disrupting attachment sites multifidus muscle. those patients,...
FAT embolism syndrome is a fatal complication after total hip arthroplasty. But its pathophysiology not exactly clear.1We report case of hemodynamic collapse fulminant fat embolism, which was supported effectively with percutaneous cardiopulmonary support (PCPS). In addition, we histopathologic analysis fatty embolisms that were captured by the artificial lung PCPS.A 76-yr-old-man right femoral neck fracture scheduled to undergo bipolar arthroplasty during general anesthesia. The patient has...
Study Design. A retrospective study. Objective. The aim of this study was to confirm that decompression for lumbar spinal stenosis (LSS) relieves low back pain (LBP) as adequately it leg and identify predictors inadequate LBP relief. Summary Background Data. Although LSS is generally thought yield worse results than pain, some studies have reported similar improvements in scores between pain. To treat or take measures prevent relief, reliable relief should be identified. Methods. We...

To maximize the benefits of posterior decompression for severe multilevel lumbar spinal stenosis, we refined expansive laminoplasty technique using a spinous process-splitting approach. This study tests hypothesis that surgical benefit adequate with element preservation is maintained in long term, over 8 years follow-up.Fifty-eight patients were followed up yearly years. Eight having nonlumbar spine surgery or Parkinson disease excluded. The noninferiority 8-year versus peak-year outcomes...
