Is synthesis always the right indication for stable intertrochanteric fractures? A case report
Fumero S., Castoldi F., Rossi M. C., Dettoni F.
A case is reported of an intertrochanteric fracture treated with DHS sliding screw in which dislocation of synthesis device and, as a consequence of its removal, a new fracture at the site of cefalic lag and plate screws occurred. Causes of synthesis failure and of second fracture and their possible reasons have been analysed: poor bone quality, errors in surgical technique, bone weakening due to cortical and lag screws, cancellous degeneration of femoral cortical bone, presence of unrecognized small fractures, altered geometry and biomechanics of the hip, lack of patient in collaboration.
