Scapular notching is thought to have an adverse effect on the outcome of reverse total shoulder arthroplasty (RTSA). However, the matter is still controversial. The aim of this study was to determine the clinical impact of scapular notching on outcomes after RTSA. Three electronic databases (PubMed, Cochrane Database, and EMBASE) were searched for studies which evaluated the influence of scapular notching on clinical outcome after RTSA. The quality of each study was assessed. Functional outcome scores (the Constant-Murley scores (CMS), and the American Shoulder and Elbow Surgeons (ASES) scores), and postoperative range of movement (forward flexion (FF), abduction, and external rotation (ER)) were extracted and subjected to meta-analysis. Effect sizes were expressed as weighted mean differences (WMD).Aims
Methods
The purposes of this study are as follows; 1) to compare postoperative blood loss between general anesthesia(GA) and spinal anesthesia(SA) and 2) to analyze the affecting factors of postoperative blood loss through the subgroup analysis. A retrospective analysis was made on the clinical data of 122 patients with osteoarthritis undergoing primary TKA between January 2012 and December 2013. According to different anesthetic method, the patients were divided into the General Anesthesia group (73 cases) and the Spinal Anesthesia group (49 cases). Each group was divided subgroup as age, BMI, Preoperative blood pressure, Surgery time, Torniquet time, INR. The total blood loss, Post Operation 1 day blood loss, hidden blood loss, and the percentage of hidden blood loss were compared between 2 groups. For the analysis of postoperative blood loss, each group was compared postoperative blood loss using hemovac drainage per day and total blood loss. In preoperative blood pressure, Higher than 140 mmHg in systolic blood pressure and higher than 90 mmHg in diastolic blood pressure were employed as a cut-off value to group the well-controlled hypertension group(n=42) and uncontrolled hypertension group(n=29)Purpose
METHODS
Antibiotic-loaded cement has been used over decades as a local antibiotic delivery for the treatment of bone and joint infections. However, there were some disadvantages such as unpredictable elution, insufficient local concentration and reduced mechanical strength. We developed hydrophilized bone cement and investigated whether it can improve consistent antibiotic release for extended periods to be effective in eradicating joint infection without any changes of mechanical strength. The experiments consists of preparation of the hydrophilized, vancomycin-loaded bone cement, In vitro test including drug release behavior, mechanical properties by compression test, cytotoxicity, antibacterial effect and animal study. In animal study, Antibiotic cement rod was implanted in the femur of rat osteomyelitis model. Sign of infections were assessed by gross observation, Micro CT and blood analysis at indicated period.Background
Methods
The proximal femur fracture in children is rare. Furthermore osteoporotic fracture associated with bone tumor make it difficult to decide the proper management method. The treatment plan should include both the treatment of the fracture and management of the condition responsible for the fracture. However, the reported literatures are rare and vary. We identified the results of treatment associated with pathologic fracture of proximal femur in children.Introduction
