Since the recent publication of studies of the vascular pattern of the proximal femoral epiphysis in man by Tucker (1949), Trueta and Harrison (1953), Judet, Judet, Lagrange and Dunoyer (1955), and Trueta (1957) there has been a renewed interest in the mechanism of capital necrosis after fractures of the femoral neck. The literature on the subject is so extensive that no effort will be made her...

Computerised tomography is useful in the diagnosis of abnormalities of the hip in children, particularly in assessing the size and shape of the acetabulum, the position and congruity of the femoral head relative to the acetabulum, and the degree of femoral anteversion or retroversion. It is most useful when limited hip movement and previous operations preclude adequate clinical examination and ...

The nuclide bone-scan will reliably diagnose Perthes' disease with a sensitivity of 0.98 and a specificity of 0.95. The comparable figures for radiographic sensitivity and specificity are respectively 0.92 and 0.78. In addition, it is possible on the scan to recognise the onset of revascularisation of the femoral capital epiphysis some months before there are radiographic signs of new bone form...

PURPOSE To biomechanically evaluate single screw and varying 2 screw fixations for an unstable slipped capital femoral epiphysis (SCFE) model using physiologically relevant loading. STUDY DESIGN In vitro biomechanical study. METHODS Twenty-four immature porcine proximal femurs were prepared to simulate a mild-to-moderate unstable SCFE. The femurs were randomized into 4 fixation groups: sing...

UNLABELLED To analyze anatomical variations of the proximal end of femur that could cause a femoroacetabular impact. METHODS 199 skeletically mature anatomical specimens of femurs were used. The femurs were measured in order to determine the anteversion angle of the femoral neck, neckshaft angle, sphericity of the femoral head at anteroposterior and superoinferior, angle between epiphysis and...

In this work, MacConaill's classification that the articular surface of the femoral head is better represented by ovoidal shapes rather than purely spherical shapes is computationally tested. To test MacConaill's classification, a surface fitting framework was developed to fit spheres, ellipsoids, superellipsoids, ovoids, and superovoids to computed tomography (CT) data of the femoral proximal ...

OBJECTIVE This study aimed to evaluate the clinical and radiographic outcomes, as well as the complications of arthroscopic subcapital realignment osteotomy in chronic and stable slipped capital femoral epiphysis (SCFE). As indicated by the literature review, this is the first time this type of arthroscopic osteotomy was described. METHODS Between June 2012 and December 2014, seven patients w...
