زیردیفرانسیل و آنالیز تقریبی روی فضاهای باناخ در این رساله با مطالعه ی دقیق مقاله proximal analysis in reflexive smooth banach spaces یک مخروط نرمال تقریبی در فضاهای باناخ بازتابی و هموار برحسب عملگر تصویر تعمیم یافته معرفی و مطالعه می کنیم. همچنین دو نوع جدید از زیر دیفرانسیل های تعمیم یافته در فضاهای باناخ بازتابی و هموار
Background: Peripheral nerve injury is one of the most challenging of modern surgical problem. Recent advances in understanding the physiological and molecular pathways demonstrated the important role of growth factors in peripheral nerve regeneration. Platelet-rich plasma (PRP) is a biological product that has many growth factors. The aim of this study was to investigate the effect of PRP in t...
Non:::union::: of femoral neck fracture in young patients is still a big problem, specially in developing countries. Between 1980 and 1998 we performed 27 cases of valgusizing osteotomy to fix non:::union::: of femoral neck fracture on patient of 17 to 74 years old with an average of 45 years. Majority of the patients had displaced fracture of femoral neck and had under gone surgery but most we...
BACKGROUND The purpose of our retrospective study was to evaluate the preliminary result of distraction osteogenesis in patient with tibial shortening after initial union of Congenital Pseudarthrosis of the Tibia (CPT). METHODS All the CPT cases with tibial shortening after initial union managed by proximal tibial lengthening using Ilizarov technique were identified. All the patient charts an...
Introduction: Proximal humerus fractures are 2nd most common of upper limb and 3rd overall. which were stable minimally displaced treated conservatively, unstable (3 part, 4 part) with ORIF Plate osteosynthesis. PO allows early mobilization fracture construct. Stability is contributed by the fixed angle construct prosthesis. This a prospective study aimed at knowing functional outcome in proxim...
Introduction: Bone graft is harvested from bone and used to stimulate bone healing due to its properties. The aims of the study were to compare the quantity of graft harvested from proximal tibia and iliac crest, and the complications at these donor sites. Materials and Methods: This was a prospective study carried out on all consecutive patients who had orthopaedic procedures that required bon...
OBJECTIVE To evaluate the clinical and radiographic results from patients who underwent femoral reconstruction secondary to loosening of total hip arthroplasty, using circumferential proximal femoral allografts and cemented implants. METHODS A retrospective study was conducted on 32 patients (33 hips) who underwent femoral reconstruction secondary to loosening of total hip arthroplasty, using...
introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...
BACKGROUND Temporary vessel occlusion of the parent artery is an essential technique for aneurysm surgery. Our aim was to clarify the safe time for temporary occlusion for aneurysm surgery, that is the "safe time duration" (STD), in which brain tissue exposed to ischemia will almost never fall into even the ischemic penumbra during temporary occlusion of the middle cerebral artery (MCA), and ev...
BACKGROUND The anatomical axis of the femur is crucial for determining the correct alignment in corrective osteotomies of the knee, total knee arthroplasty (TKA), and retrograde and antegrade femoral intramedullary nailing (IMN). The aim of this study was to propose the concept of different anatomical axes for the proximal and distal parts of the femur; compare these axes in normally aligned su...
