condylar dislocation is not an uncommon condition and occurs when the condyles are displaced anterior to the articular eminence and are unable to reduce back into the glenoid fossa. long-standing dislocations are difficult to treat with the conservative methods and usually need surgical intervention. in this paper, a long-standing dislocation treated by bilateral extra-oral ramus osteotomy is d...

The goal of this study was to evaluate the accuracy of the lesser trochanter for entry of lag screw placement in the fixation of hip fractures. Radiographs of the pelvis with both hips in 50 Chinese patients were analyzed to determine the accuracy of using the lesser trochanter as a reference landmark for inserting lag screws. The femoral neck was divided into 4 parts, and the second distal par...

The purpose of this study is to quantify the lesser trochanteric version and determine the angle and the relationship between lesser trochanter and femoral neck version. Investigate the influence of the lesser trochanter version in the width of ischiofemoral space. Two hundred and fifty asymptomatic hips were evaluated with axial magnetic resonance image. The lesser trochanter version was calcu...

A new species Xerobion ulytavicum Kadyrbekov sp. n. from host plant Galatella biflora is described Karaganda region (Kazakhstan). New differs the most similar X. caspicae Bozhko, 1963 by shape of ultimate rostral segment, ratio length siphunculi and cauda (0.4–0.75 vs 0.7–1.0, respectively), proportion frontal setae to diameter third antennal segment at base (1.0–1.2 0.7–1.0) a hair on trochant...

o bjectives: the aim of this study was to investigate the displacement and stress distri- bution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. materials and methods: three-dimensional (3d) finite element model of a maxilla was constructed and an expansion force of 100 n was applied to the left and right molars and pr...

BACKGROUND Legg-Calve´-Perthes disease is a juvenile idiopathic osteonecrosis in which the blood supply of femoral head is not sufficient and the bone dies provisionally. The aim of this study is to evaluate outcome of Femoral osteotomy in children with LCPD in our University Hospital. METHODS In a descriptive analytic study, between 2008 and 2013, patients with the diagnosis of Legg-Calve'-P...

Cemented Bipolar arthroplasty is an established method for treatment of comminuted Intertrochanteric fractures. Reconstruction of greater trochanter is an essential technical step to avoid complications like abductor lurch gait. We here describe a technique of reconstruction and fixation of greater trochanter using cancellous screws with wide washers made of reconstruction plate and tension ban...

We report the case of a 40-year-old patient hospitalized for inflammatory pain involving the superior external part of the right thigh; which has been evolving for 8 months, without alteration of the general condition or fever. On physical examination, pain was elicited by applying direct pressure over right greater trochanter without signs of local inflammation. Laboratory tests did not show a...

Background. Selection of entry point for nail insertion is controversial and lack firm anatomical basis. The study is done to analyze the proximal anthropometry of femur and measure the Trochanter-Shaft Angle to find its relation and significance in selection of entry point for antegrade uniplanar femoral nail. Materials and Methods. Study involves the measurement of trochanter-shaft angle and ...

OBJECTIVE To analyze the natural exit of the wire guides in major trochanter through retrograde femoral approach, in cadaver specimens. MATERIAL AND METHOD 100 femurs had been perforated between the femoral condyles, at 1.2 cm of the intercondylar region. A 3-mm straight wire guide was introduced, through retrograde approach, until the proximal extremity of femur was reached. Femurs were asse...
