INTRODUCTION: Modular neck total hip arthroplasty (THA) devices afford the surgeon increased intra-operative flexibility in terms of the degree of head version and offset, as well as allowing more controlled stem positioning. Strains on the outer cortical bone surface have been shown to be strongly dependent on the orientation of a THA. These strains can be a potential cause for mechanical fail...

im: This study was performed to examine morphometric and morphological characteristics of the fovea for ligament head femur (FLHOF) on dry determine its location types.
 Material Method: FLHOF analyzed morphometrically morphologically 57 adult femora (27 right; 30 left) their digital images. Dimensions surface area were measured using a caliper bone ImageJ software images.
 Results: T...

Posterior hip dislocation with greater trochanter fracture is an uncommon injury pattern in the acute trauma patient. Frequently associated includes a combination of posterior wall acetabulum, head femur fracture, intertrochanteric and even most severe type combined acetabular fracture. We report 42-year-old man post traumatic bilateral injuries irreducible isolated trochanteric successfully ma...

The current study was conducted to investigate the effects of dietary iron-loaded chitooligosacharide nanoparticles (Fe-CNP) on occurrence of bacterial chondronecrosis with osteomyelitis (BCO) in broiler chickens. Four hundred eighty day-old chicks (Ross 308) were assigned to four treatments with six replicates of 20 birds. All chicks were reared on wire flooring system up to 42 days of age. Th...

This review considers methods used to quantify lag screw placement within the femoral head following proximal femoral fracture. Implants used for fixation of femoral neck fractures can lead to unwanted outcomes in some patients. Cutting out of the screw within the femoral head has been shown to be the commonest cause of failure and is related to lag screw placement within the femur. Until now, ...

Method: This study is further analysis of data in a case report of a dichorionic-dizygotic twin pregnancy in which one twin (Twin-A) presented three months postnatally with seizure. The other twin (Twin-B) developed normally and so became a control. The twins showed similar head growth up to 24 weeks but subsequently the rate of head growth of Twin-A exceeded that of Twin-B. Later, from 29 week...

This paper discusses the design of a navigation system developed to assist surgeons in the procedures of Hip Resurfacing prosthesis surgeries. In conventional surgery, mechanical jigs are used to obtain a correct alignment for the metal prosthesis, however it is a very time consuming process. In order to solve this problem emerges a new robotic system, named HipRob. The system is composed by a ...

Extensive osseous adaptations of the lumbar spine, pelvis, hip and femur characterize the emergence of the human bipedal gait with its 'double extension' of the lumbar spine and hip. To accommodate lumbar lordosis, the pelvis was 'compacted', becoming wider and shorter, as compared with the non-human apes. The hip joint acquired a much more extended position, which can be seen in a broader evol...

We studied the morphological changes in the proximal femur in 42 patients (42 hips) who had had varus derotation osteotomy of the upper femur for residual acetabular dysplasia and congenital subluxation of the hip and who did not show deformity of the head of the femur. In 19 patients the alignment of the whole leg was examined. The femoral neck-shaft angle (FNSA) at the final examination was u...

We have observed damage to the labrum as a result of repetitive acetabular impingement in non-dysplastic hips, in which the femoral neck appears to abut against the acetabular labrum and a non-spherical femoral head to press against the labrum and adjacent cartilage. In both mechanisms anatomical variations of the proximal femur may be a factor. We have measured the orientation of the femoral n...
