Abstract
An orthopaedic implant is provided for the treatment of avascular necrosis of the bone. The orthopaedic implant includes a hollow support structure and a synthetic vascular graft. The support structure defines a passageway and includes a proximal opening and a distal opening. The synthetic vascular graft is received, at least in part, within the passageway such that a proximal end portion of the synthetic vascular graft is received through the proximal opening of the support structure and a distal end portion of the synthetic vascular graft is received through the distal opening of the support structure.

An orthopaedic implant for the treatment of avascular necrosis of the bone, the orthopaedic implant comprising:
- a hollow support structure defining a passageway and having a proximal opening and a distal opening, and
- a synthetic vascular graft received, at least in part, within the passageway of the hollow support structure such that a proximal end portion of the synthetic vascular graft is received through the proximal opening of the hollow support structure and a distal end portion of the synthetic vascular graft is received through the distal opening of the hollow support structure.
An orthopaedic implant for the treatment of avascular necrosis of the bone, the orthopaedic implant comprising:
- a fenestrated hollow support structure defining a passageway and having a proximal opening and a plurality of distal openings,
- a synthetic vascular graft received, at least in part, within the passageway of the hollow support structure such that a proximal end portion of the synthetic vascular graft is received through the proximal opening of the hollow support structure and a trifurcated, distal end portion of the synthetic vascular graft is received through distal openings of the hollow support structure.
A method of vascularizing a necrotic portion of a bone comprises the steps of:
- inserting a synthetic vascular graft into a passageway of a hollow support structure,
- implanting the hollow support structure and the synthetic vascular graft into a predrilled channel of the bone, and
- suturing the synthetic vascular graft to a vein and artery of the bone.
