This allows placement of screws on the outside of the acetabulum away from the surface which is to be reamed. The graft is stressed by the implant superiorly so that incorporation can occur. The graft trabeculae are also oriented in a vertical direction to permit maximum strength of the graft (Figs. 7). Type2C Where there is protrusio defect, we prefer to use cancellous chips because incorporation is faster. The support and stability of the acetabular component are achieved by rim support. The protrusio portion of the acetabulum which has been grafted should not be relied upon for any significant support.
On occasions in the autograft situation, it may be better to use a good allograft than an osteoporotic autograft femoral head with a dysplastic hip. Cancellous surfaces should only be exposed to the cup and not to the soft granulation tissue. In our opinion, it is essential for good internal fixation that some form of plate or ring from host bone to host bone should be used with the screws in an oblique to vertical direction. G. Paprosky A systematic approach has been developed in the new field of reconstructive surgery.
Despite the application problems, these reported results in 64 patients at one year (16% failure rate) are encouraging. The ceramic/collagen/marrow graft is inserted in a paste-like consistency around the outer fracture margins and into the fracture itself, simulating the spontaneous callus formation around the fracture (Kocialkowski and Wallace 1991, 1992). The advantages of artificial graft substitutes are an increase of graft surface and contact area, and healing may take place simultaneously over the whole graft area.
