Abstract
Modular acetabular reconstruction apparatus includes a generally cup-shaped portion adapted for fixation within a human pelvis and one or malleable extension arms adjustable in multiple dimensions. Each arm preferably includes one or more apertured sections spaced apart from one another by a necked-down section enabling each arm to be manipulated in three dimensions for intimate physical conformity with surrounding bone. The back surface of the generally cup-shaped portion may be adapted for a cemented or a non-cemented interface within a human pelvis; as such, the back surface may be adapted for porous bone in-growth. According to a disclosed method, the step of bending each arm in multiple dimensions may be carried out a part of a trial joint reduction. Various bending tools and techniques are also set forth.
Claims7
Modular acetabular reconstruction apparatus, comprising:
- a generally cup-shaped portion having a peripheral rim and a back surface, wherein at least a portion of the back surface includes porous bone in-growth material facilitating cementless fixation relative to a human pelvis;
- one or more malleable extension arms connected to the peripheral rim of the cup-shaped portion facilitating fixation of the apparatus to surrounding bone;
- two adjacent malleable extension arms adapted for overlying contact with the bone surrounding the acetabulum;
- and
- an apertured bridge element between the two arms.
