BACKGROUND Bioabsorbable interference screw fixation has superior biomechanical properties compared to suture anchor fixation for biceps tenodesis. However, it is unknown whether fixation technique influences clinical results. HYPOTHESIS We hypothesize that subpectoral interference screw fixation offers relevant clinical advantages over suture anchor fixation for biceps tenodesis. STUDY DES...

Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...

BACKGROUND During the early postoperative period, the fixation of a hamstring graft to the bone tunnel is the primary factor in limiting rehabilitation. HYPOTHESIS The initial fixation strength of a double cross pin fixation technique is comparable with the biodegradable interference screw fixation technique. STUDY DESIGN Experimental laboratory study. METHODS The authors examined the ini...

INTRODUCTION: Bone conserving designs, such as hip resurfacings, are an alternative treatment option to conventional total hip arthroplasty (THA) in young, active patients. Previous studies have shown that medullary fixation can result in significant proximal bone resorption through stress shielding [1,2], while it has been suggested that hip resurfacing arthroplasty will load the proximal femo...

OBJECTIVE To review the clinical performance of the anatomic medullary locking (AML) femoral stem in total hip arthroplasty. DESIGN A clinical and radiographic review. SETTING A tertiary lower limb joint replacement centre. PATIENTS Two hundred and twenty-one patients with noninflammatory gonarthrosis. INTERVENTIONS Two hundred and twenty-seven primary total hip arthroplasties with the ...

BACKGROUND Fixation of an anterior cruciate ligament graft at the joint line with an interference screw restores anterior laxity better than low-stiffness distal fixation with double staples and sutures tied to a post at implantation in porcine bone. HYPOTHESIS Fixation of an anterior cruciate ligament graft with a high-stiffness distal fixation device restores anterior laxity and knee stiffn...

With today’s aging population, musculoskeletal diseases such as osteoporosis, degenerative arthritis, and degenerative spine disease, are on the rise, and these conditions are associated with increased fracture risk. Intertrochanteric fractures in elderly patients often involve severe displacement or comminution with poor bone quality. Accordingly, various treatment methods for hip fracture hav...

BACKGROUND Despite increasing attention on fixation of a soft tissue anterior cruciate ligament graft in the tibia, there have been no studies on the use of a bone dowel as a joint line fixation device for promoting fixation properties, especially stiffness at the time of implantation. PURPOSE To determine whether compacting a bone dowel into the tibial tunnel improves fixation stiffness, yie...

mumps is an acute contagious viral disease that usually manifests as inflam¬mation of the parotid glands. the disease may be associated with symptoms such as parotitis, orchitis and meningoencephalitis. 85% of cases occur in children under 15 years of age. the disease is rare below two years but increases with age, reaching a maximum at 5 to 9 years. some studies in iran showed that the highest...
