[Long-term results following acetabuloplasty using cortico-spongiosa banked chips in hip dysplasia and dislocation].

Analysed are altogether 119 acetabuloplasties correcting acetabular fossae using corticospongiose bankchips. The operations of the years from 1975-1983 have been used for this analysis. Examined are by clinical progress and serial roentgenography the compatibility, the resistance to mechanical stress as well as building in and transformation of the corticospongiose bankchips. Finally is determined the progress of the socket by using the socket-roof- and centre-corner-angle postoperative on an average of 10 years.
