[ESKA (CUT) endoprosthesis].

The ESKA femoral neck endoprosthesis (CUT) is a mini endoprosthesis anchored in the metaphysis for surgical management of young arthrosis patients with good bone quality. The necessary surgical intervention can be considered minimally invasive and adequate because only the affected femoral head is removed. The preserved femoral neck is used for fixation of the endoprosthesis to obtain proximal physiological force transmission and avoid stress shielding.

Epiphysiolysis of the hip: relationship between etiopathogenesis and hormone status.

The authors present a review of the literature on the etiology of epiphysiolysis of the hip and an original study on the hormone status of these patients. By examining eleven values including hormones, vector proteins, and hormonal transport, the authors related the data obtained to the anagraphical age of the patient, to his or her skeletal age, to the development of sexual features, and to the radiologic evidence of pathology. In light of the results obtained, despite the fact that the study only included 23 patients, the modified equilibrium between SHBG and Somatomedin C, would seem to lead to an accelerated turnover in the growth plate.
