The primary purpose of this meta-analysis was to determine whether statin usage could reduce the risk of glucocorticoid-related osteonecrosis in animal models. A systematic literature search up to May 2015 was carried out using the PubMed, Ovid, EBM reviews, ISI Web of Science, EBSCO, CBM, CNKI databases with the term and boolean operators: statins and osteonecrosis in all fields. Risk ratio (RR), as the risk estimate of specific outcome, was calculated along with 95% confidence intervals (CI). The methodological quality of individual studies was assessed using a quantitative tool based on the updated Stroke Therapy Academic Industry Roundtable (STAIR) recommendations.Objectives
Methods
Pathological fractures in children can occur
as a result of a variety of conditions, ranging from metabolic diseases and
infection to tumours. Fractures through benign and malignant bone
tumours should be recognised and managed appropriately by the treating
orthopaedic surgeon. The most common benign bone tumours that cause pathological
fractures in children are unicameral bone cysts, aneurysmal bone
cysts, non-ossifying fibromas and fibrous dysplasia. Although pathological
fractures through a primary bone malignancy are rare, these should
be recognised quickly in order to achieve better outcomes. A thorough
history, physical examination and review of plain radiographs are
crucial to determine the cause and guide treatment. In most benign
cases the fracture will heal and the lesion can be addressed at
the time of the fracture, or after the fracture is healed. A step-wise
and multidisciplinary approach is necessary in caring for paediatric
patients with malignancies. Pathological fractures do not have to
be treated by amputation; these fractures can heal and limb salvage
can be performed when indicated.
To employ a simple and fast method to evaluate those patients with neurological deficits and misplaced screws in relatively safe lumbosacral spine, and to determine if it is necessary to undertake revision surgery. A total of 316 patients were treated by fixation of lumbar and lumbosacral transpedicle screws at our institution from January 2011 to December 2012. We designed the criteria for post-operative revision scores of pedicle screw malpositioning (PRSPSM) in the lumbosacral canal. We recommend the revision of the misplaced pedicle screw in patients with PRSPSM = 5′ as early as possible. However, patients with PRSPSM < 5′ need to follow the next consecutive assessment procedures. A total of 15 patients were included according to at least three-stage follow-up.Objectives
Methods
To investigate the appropriate dose and interval for the administration
of triamcinolone acetonide (TA) in treating tendinopathy to avoid
adverse effects such as tendon degeneration and rupture. Human rotator cuff-derived cells were cultured using three media:
regular medium (control), regular medium with 0.1 mg/mL of TA (low
TA group), and with 1.0 mg/mL of TA (high TA group). The cell morphology,
apoptosis, and viability were assessed at designated time points.Objectives
