Epiphyseal distraction and centrally located bone bar: an experimental study in the rabbit.

The purpose of this study was to analyze the force required for an epiphysiolysis in vitro in the distal femoral growth plate of rabbits with different sized central physeal bone bars. The bars were operatively induced by drilling through the physis. An epiphyseal distraction was then performed, and the response was evaluated. Forty rabbits (67 femurs) divided into five groups were used for experimentation. Group A had not been operated on and manifested no physeal bone bridge. Groups B, C, D, and E manifested some bone bridges obtained surgically by drills 2, 2.5, 3.5, and 4.5 mm in diameter, respectively. The average force required to obtain an epiphysiolysis is not statistically significant in the different groups. However, we noted that the epiphysiolysis differed depending on the diameter of the surgically performed bridge. Group E was Salter-Harris type II fractures, whereas groups A, B, and C were type I fractures. Group D comprised both types.

Is the Cotrel-Dubousset really universal in the surgical treatment of idiopathic scoliosis?

We reviewed the results of 22 cases of Cotrel-Dubousset (C-D) instrumentation, 16 cases of anterior approach, and 200 cases of posterior approach by Harrington instrumentation and modifications of Harrington procedure. Posterior spinal fusion and instrumentation by C-D gives better correction and stabilization in thoracic and balanced double major curves. We no longer use the Harrington procedure and its modification. In lumbar and short thoracolumbar curves, VDS is still preferred. In some double major curves combined procedures, VDS and C-D are used to obtain more correction with a shorter fusion area.

New procedure to remove a centrally located bone bar.

A centrally located bone bar of the lower tibia was removed after epiphyseolysis with an Ilizarov device. The bone bridge attached to the metaphysis was easy to remove, and methylmethacrylate was used as an interpositional material. Varus deformity was corrected at the level of the epiphyseolysis. At the 2-year follow-up, there was evidence of further growth and correction of the varus was maintained.

Bone lesions in histiocytosis X.

Sixty-two patients with histiocytosis X were followed for an average of 5 years. The patients were classified into three groups: general visceral types (14 cases), multiple eosinophilic granulomas (nine cases), and solitary eosinophilic granulomas (39 cases). One hundred bony lesions were noted in 60 of the 62 patients. The bone lesions showed progressive improvement in single and multiple eosinophilic granulomas independent of treatment type. After biopsy, patients received no treatment unless there was a dangerous extension into the soft tissues because of its site, i.e., in the skull. In the general visceral types, chemotherapy was effective in visceral sites and in extensions of the tumor outside the bone but did not alter the natural history of the bony lesion.

Acetabular anteversion in children.

Acetabular anteversion analysis was performed in 143 normal children, who ranged in age from 1 to 15 years. The mean anteversion value, which remained constant during growth, was 13 degrees.

[Autonomy of the nursing profession: state of the art].

This article points out the foundation elements of the nursing education, the way covered till now, the status of the art and what has to be achieved in order to attain Nursing Degree objectives. The different aspects concerning the curricula organization and the model of care are examined. The request of getting nursing teaching and nursing chairs for nurses are an aim not yet met, but they are the basis objectives of the professional engagement. Another important subject concerns the leadership that will allow nurses to be administrators and managers in every respect, also from a juridical point of view, and to express their professionality in a really autonomous way.
