Stress fractures of the tarsal navicular do not heal predictably with conservative treatment, so we recommend operation if the fracture remains symptomatic, and radiographs show wide separation of a complete fracture, extension of an incomplete fracture, delayed healing, or a medullary cyst. An autologous bone graft is inserted after en-bloc resection of the fracture surfaces. It is important t...

We tested the hypothesis that children who sustain a supracondylar fracture have a greater range of elbow hyperextension than those with a fracture of the distal radius. Three observers made 358 measurements in 183 children (114 boys and 69 girls). There were 119 fractures of the distal radius and 64 supracondylar fractures. Initially, the group with a supracondylar fracture appeared to have ex...

BACKGROUND Patients suffering from polytrauma often present with altered mental status and have varying levels of examinability. This makes evaluation difficult. Physicians are often required to rely on advanced imaging techniques to make prompt and accurate diagnoses. Occasionally, injury detection on advanced imaging studies can be challenging given the subtle findings associated with certain...

From an anatomical study and clinical review of fractures of the lateral humeral condyle in children, the following conclusions are drawn. The mechanism of injury is a violent varus force with the elbow in extension, the condyle being avulsed by the lateral ligament and the extensor muscles. If the fracture is incomplete, with an intact hinge of pre-osseous cartilage medially, the fragment will...

It is unclear whether there is a limit to the amount of distal bone required to support fixation of supracondylar periprosthetic femoral fractures. This retrospective multicentre study evaluated lateral locked plating of periprosthetic supracondylar femoral fractures and compared the results according to extension of the fracture distal with the proximal border of the femoral prosthetic compone...

Anterior to posterior (AP) pinning is the recommended sagittal pin configuration in divergent lateral entry coronal of pediatrics supracondylar fractures. However, there was still a lack evidence regarding alternative pins configurations. We aimed compare construct stiffness configurations by using synthetic bone models. Sixty pediatric humeri were osteotomized create fracture. After fracture r...

Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...

This chapter surveys mathematical methods and principal results in the mechanics of fracture. Primary emphasis is placed on the analysis of crack extension as treated through methods of conti~uum mechanics. Section II begins 191

BACKGROUND Various treatments of giant cell tumor of bone (GCTB) included in curettages and resections and with adjuvant are exerted, but the best treatment is controversial. The aim of the study was the identification of individual risk factors after various treatments in GCTB. METHODS A total of 179 patients treated for GCTB between 1998 and 2010 were concluded in the retrospective study. A...

This is a retrospective study reviewing 19 patients with mallet treated by extension block pinning method between 2013-2016. By Wehbe and Schneider and Doyle’s classification 13 cases of type IIB, 4 of IIC and 1 case each of IB and IC.15 were treated acutely and 4 subacutely and followed up for a mean period of 20.13 weeks. We obtained 11 excellent results, 4 good result and 4 fair outcomes by ...
