Burch-Schneider Reinforcement Cage
The Burch-Schneider Cage made of pure titanium (Protasul-Ti) is rough-blasted on the side facing bone.
It consists of a central shell with a proximal flange for fixation to the ilium and a distal nose for stabilization in or on the ischium.
The shell (which comes in 44, 50, 56 and 62 mm sizes) is hemispherical, open at the tip of the cup, and displays a rough, sieve-like surface pattern.
In the curvature for the acetabular roof here are preformed anchorage holes for screw fixation to the iliosacral joint. The proximal flange is angled 22°
posteriorly with respect to the middle of the shell (or the nose). Models for left and right are correspondingly designed.
In addition, the shell flange and nose are both bent medially, and the proximal flange is also curved posteriorly.
