Background: An osteological study of femur provides useful data to understand various diseases of femur and serves as a guide for the treatment of various pathological conditions of it. Aim: The purpose of this study is to determine the various parameters of femur among south Indian population and to compare them with the data available worldwide. Materials and Methods: A total of 158 adult fem...

Reverse shoulder arthroplasty may be performed using components that medialize or lateralize the center of rotation. The purpose of this prospective study was to directly compare 2 reverse shoulder arthroplasty designs. Two treatment groups and 1 control group were identified. Group I comprised 9 patients using a medialized Grammont-style (GRM) prosthesis with a neck-shaft angle of 155°. Group ...

The aim of this study was to investigate the long-term clinical outcomes of valgus osteotomy combined with intramedullary nail for the treatment of shepherd’s crook deformity of polyostotic fibrous dysplasia. We reviewed the clinical data of 22 patients with polyostotic fibrous dysplasia that was treated at our department between January 1995 and January 2010. All 22 of the patients (23 femurs)...

A typical passive magnetic bearing has been modeled and analyzed for its performance characteristics. The magnetic bearing studied in this work comprised of a Shaft, inner magnets sleeved over the shaft, and outer magnetic rings. A detailed analysis has been perform on the force exerted by a permanent magnet on the shaft nurture to restore the shaft to its equilibrium position when an eccentric...

The results of the simulation used a propeller disk actuator method that models effect without modeling real propeller. Direct optimization will be calculated using CFD each variation clearance configuration indicating amount propulsion efficiency produced is very dependent on most optimal occurs at distance 0.738 m from steering shaft with Dprop = 0.88, KT 0.22, KQ 0.028, and J 0.40 besides ha...

The aim of this study was to assess the influence of bone mineral density and hip geometry on the fragility fracture of femoral neck and trochanteric region. There were 95 menopausal females of age ≥ 50 years with fragility fracture of hip, including 55 cases of femoral neck fracture and 40 cases of trochanteric fracture. Another 63 non-fractured females with normal bone mineral density (BMD) w...

OBJECTIVE To ascertain the geometry of the femur in the Brazilian population by means of a radiographic study and to correlate the values with regard to sex and right/left side. METHODS Five hundred anteroposterior radiographs of the pelvis of skeletally mature patients (250 of each sex) who did not present any osteoarthrosis, fractures or tumoral or infectious lesions were analyzed. The leng...

In view of the torsional vibration problem main drive system F5 rolling mill in a steel plant, two sets torque monitoring sensors were installed on cross universal joint shaft site. Through online monitoring, it is found that frequency twice rotational system, and amplitude upper greater than lower shaft. Considering influence inclination angle shaft, transmission can be simplified as multi-bod...

In order to improve the heat transfer between high-temperature sinter and cooling gas in a vertical shaft cooler, new furnace type with variable-diameter structure was proposed, influence of on gas–solid vertical-shaft cooler studied by CFD-DEM coupling method current work. The results show that can increase quantity low-temperature as well outlet temperature, uniformity temperature along width...
