Acetabular reconstruction using the Kerboull reinforcement device and allograft

Invented by Marcel Kerboull in 1975 to deal with transverse acetabular fractures secondary to failed metal-on-metal total hip arthroplasty, this device continues to be used successfully, primarily in France and Japan, where articles are frequently published describing long-term results that demonstrate the efficacy of the implant when it is combined with allograft.

Introduction

Invented by Marcel Kerboull in 1975 to deal with transverse acetabular fractures secondary to failed metal-on-metal total hip arthroplasty (Fig. 1), this device continues to be used successfully, primarily in France and Japan, where articles are frequently published describing long-term results that demonstrate the efficacy of the implant when it is combined with allograft.(1,2,3)

Mainly used for revision total hip arthroplasty where loosening of the implant has resulted in bone loss, the device can also be used in primary replacements to reinforce weakened or destroyed bone, as well as when the native anatomy has been affected by a fracture of the acetabulum or acetabular salvage procedures such as a Chiari osteotomy.

Even though the surgical technique has been published4 and is often discussed at conferences, we thought it appropriate to describe it anew because the majority of early failures are caused by the surgeon either misunderstanding or failing to follow the technique.

 

Mechanical principles

This semi-rigid device is used to reinforce the graft during partial or total osseointegration but, thanks to its shape and perfect positioning, it can also be helpful...
