Stress fractures of the tibia secondary to tibial deformities from osteoarthritis are rare, and may be difficult to manage. We treated two patients with stress fractures of the proximal tibial diaphyses over a period of two years. Both patients had osteoarthritis of the knee; one with genu valgus deformity and the other, genu varus deformity. The former patient also had a distal tibial fracture...

Background and purpose - Bone fragility is determined by bone mass, bone architecture, and the material properties of bone. Microindentation has been introduced as a measurement method that reflects bone material properties. The pathogenesis of underlying stress fractures, in particular the role of impaired bone material properties, is still poorly understood. Based on the hypothesis that impai...

Stress fractures of the third metacarpal bone (McIII) are a common cause of lameness in Thoroughbred racehorses. The most commonly described location is the mid-dorsolateral cortex (Copelan 1979; Richardson 1984, 1999; Stashak 1987; Stover et al. 1988; Cervantes et al. 1992; Pilsworth and Shepherd 1997; Stover 1998; Sullins 1998), but they also occur distally and proximally in the dorsal cortex...

Seven patients with stress fractures of the femoral neck were treated at the Military Hospital of Thessaloniki, Greece between 1972 and 1976. Their average age was 22 years. Stress fractures of the femoral neck are not as common as stress fractures of the metatarsals or tibia and other bones. Intense muscular activity was the main cause of these stress fractures which were only classed as such ...

INTRODUCTION Hamulus fractures are uncommon injuries constituting 2-4% of carpal fractures and are usually reported in athletes. Stress fractures of hamulus are even rarer and very few cases have been reported till date. In this case report, we present the first documented case of stress fracture of hamulus in a cricket batsman and review the existing literature on hamulus fractures, both acute...

Background: Presentation of proximal tibia stress fracture is not infrequent among elderly patients due to their poorbone stock. Optimal management of patients with severe gonarthrosis of the knee and concurrent tibial stress fracture isnot known yet. In this study we report the outcome of primary total knee arthroplasty (TKA) using stemmed componentsin elderly patients.Methods: Between 2009 an...

most of the earth's crust contains fluids, and fractures are common throughout the upper part. they exist at a wide range of scales from micro-fractures within grains to major faults and shear zones that traverse the crust. in this paper, the stress-dependent permeability in fractured rock masses have been investigated considering the effects of nonlinear normal deformation and shear dilation o...

The image logs interpretation from two wells in a fold hosting a west Iranian oil field located in the Dezful Embayment, SW Iran reveal the occurrence of two major systems of natural fractures. In the central part of the fold, the fold-related fractures include two sets of fractures trending N53°E and N34°E. In the eastern and also curved part of the fold, the strike of open fractures varies fr...

Navicular stress fractures in athletes are notoriously difficult to diagnose, resulting in an average delay in diagnosis of 4 months after the onset of symptoms. There are various reasons for this delay. Navicular stress fractures are characterised by an unspecific symptomatology combined with a paucity of physical findings. Furthermore there is difficulty in visualising stress fractures on pla...
