To investigate the feasibility and accuracy of combining a personalized finite element analysis with 3D-printed navigation template on treatment femoral neck fracture (FNF) cannulated screw. A total 60 patients as unstable FNT were evolved randomly divided into two groups. The subjects in study group examined using according to three-dimensional CT hip joint before operation then underwent femu...

We here present an 11-year-old patient with bilateral Hawkins type 3 talus neck fractures resulting from a fall height. When the was brought to Emergency Department, ankles were edematous and there subtalar dislocation. The taluses on both sides entered anteromedial anterolateral incisions, after open reduction, fixed one cannulated screw anterior posterior side. No additional edema developed. ...

The compression produced by and the resistance to pullout of the 6.5 mm cannulated Herbert screw were compared with those of ASIF headed screws. The latter were tested with and without washers and in the following sizes: 4.5 mm cortical, 6.5 mm cancellous with a 16 mm threaded segment, and 6.5 mm cancellous with a 32 mm threaded segment. Polyurethane foam was used as a substitute for cancellous...

INTRODUCTION Although elbow fractures have a high incidence in the pediatric population, fractures of the capitellum are almost exclusively observed in individuals older than 12 years of age. Due to their rarity in children, reports with large numbers of cases are lacking in the literature and the surgical treatment options are poorly defined. CASE PRESENTATION We present the case of an 11-ye...

INTRODUCTION Osteoblastoma is a rare (incidence <1%) benign locally aggressive osteoblastic lesion of bone with rare malignant transformation. Benign osteoblastoma is the term used by Jaffe to denote an uncommon neoplasm of bone characterized by vascular osteoid and bone forming matrix rich in osteoblasts. CASE REPORT Here we report a case of osteoblastoma of talus in eighteen year old male p...

BACKGROUND Attritional bone loss in patients with recurrent anterior instability has successfully been treated with a bone block procedure such as the Latarjet. It has not been previously demonstrated whether cortical or cancellous screws are superior when used for this procedure. PURPOSE To assess the strength of stainless steel cortical screws versus stainless steel cannulated cancellous sc...

A 30-year-old patient sustained the fracture in a motorcycle accident. A triplane-type of fracture of the distal femur was confirmed by CT scan. The trochlear fragment was reduced anatomically and was stabilized with 6.5mm cannulated screws. Once reconstruction of the coronal plane fracture was performed, the split lateral condylar fragment was fixed with a cannulated screw to the medial fragme...
