Pediatric hip fractures and dislocations are rare in practice and are related to high-energy trauma. The incidence of postoperative avascular necrosis is increasing, especially in the case of transepiphyseal fractures. Surgery is the most common form of treatment, and its timing is important for prognosis of the fracture. Patients and their families should be informed about the possibility of a...

RESULTS During the eleven-year period 1957-1967, the case records of 495 patients with fracture of the femoral neck were available for study. There were 120 male and 376 female cases; one female patient had fractures of both femora at different times and therefore there were 496 fractures included in the series. The diagnosis was confirmed radiologically in all cases. Fig. 1 shows the age distr...

The miscible displacement process appears to be an increasingly feasible method for the extraction of oil from depleted reservoirs. How‌ever, there is a lack of fundamental understanding of how fracture geometrical characteristics impact the oil recovery efficiency in this type of enhanced oil recovery technique. In this work, a series of experimental tests were conducted whereby the n-Hept...

Trauma is often related to functional impairment, representing an important social, economic and health issue. This study intended to evaluate the functional independence of aged individuals with fractures, at admission, discharge and after one month from their regressing home. Furthermore, this study also intended to verify the relationship between functional independence and demographic and h...

INTRODUCTION: Hip fracture is the most serious complication of osteoporosis. In order to develop and target prevention strategies, it is essential to find those at increased risk of hip fracture. Decreased bone mineral density (BMD) in the proximal femur is associated with hip fracture risk, but majority of the fractures occur in patients without osteoporosis . Fracture risk is also affected by...

OBJECTIVE To investigate seasonal variations in the incidence of fall related fractures among people 65 years and older. POPULATION AND METHODS A prospective, population based cohort study was performed on people aged 65 years and older followed up from 1990 to 1997, a total of 459,904 person years. Cases were identified through a prospective registration system. RESULTS There were 10,992 (...

Based on the systematical observations of cores, thin sections, and scanning electron microscope (SEM) together with testing data characteristic parameters, this paper discussed characteristics controlling factors fractures, their control shale gas accumulation in Lower Cambrian Niutitang Formation black reservoir Well YX1 northern Guizhou Province. The results show that macro structural fractu...

It is a routine protocol to examine the soft tissues, cartilage and bone tissues of neck during post-mortem examinations performed in cases hanging-related deaths. Fractures hyoid thyroid cartilage, as well bleeding ecchymoses around first fracture are practically great importance establishing case live hanging. The styloid process thin at base skull that extends downward, medially, anteriorly ...

The aim of this study was to determine the prevalence of self- reported versus diagnosed stress fractures in female elite athletes and non-athletic controls. A random sample of Norwegian elite athletes from the national teams, aged 13-39 years (n = 186) and a random sample of non-athletic controls (n = 145) in the same age group participated in the study. The athletes represented a junior- or s...
