Abstract
This disclosure details surgical instrumentation and related techniques for performing bone reconstruction surgeries. The surgical instrumentation may be used to size and shape a graft, such as an allograft. The appropriately sized and shaped graft is subsequently used to reconstruct damaged bone. A surgical instrumentation set is used to prepare the graft. The surgical instrumentation set includes a graft workstation, a plurality of sizing blocks and a plurality of cutting blocks.
Claims18
A surgical instrumentation set, comprising:
- a graft workstation configured to receive a bone block, said graft workstation including a cutting jig movable relative to said bone block;
- a plurality of sizing blocks configured to estimate a size of a bone graft to be harvested from said bone block;
- and
- a plurality of cutting blocks interchangeably connectable to said cutting jig and each configured to guide at least one cut in said bone block to form said bone graft,
- wherein said surgical instrumentation set is provided as part of a kit for performing a bone reconstruction surgery,
- wherein said kit includes said graft workstation, said plurality of sizing blocks, said plurality of cutting blocks, and one or more guide wires, drills, guide pins, and drill guides.
A surgical instrumentation set, comprising:
- a graft workstation configured to receive a bone block, said graft workstation including a cutting jig movable relative to said bone block;
- a plurality of sizing blocks configured to estimate a size of a bone graft to be harvested from said bone block;
- a plurality of cutting blocks interchangeably connectable to said cutting jig and each configured to guide at least one cut in said bone block to form said bone graft;
- and
- a parallel drill guide without prongs and a parallel drill guide with prongs that are each configured to retrieve said bone graft from said bone block.
A surgical instrumentation set, comprising:
- a graft workstation configured to receive a bone block, said graft workstation including a cutting jig movable relative to said bone block;
- a plurality of sizing blocks configured to estimate a size of a bone graft to be harvested from said bone block;
- a plurality of cutting blocks interchangeably connectable to said cutting jig and each configured to guide at least one cut in said bone block to form said bone graft;
- and
- a cutter guide configured to be inserted into a slot of at least one of said plurality of cutting blocks.
A surgical method that employs a surgical instrumentation set comprising a graft workstation configured to receive a bone block, the graft workstation including a cutting jig movable relative to the bone block, a plurality of sizing blocks configured to estimate a size of a bone graft to be harvested from the bone block, and a plurality of cutting blocks interchangeably connectable to the cutting jig and each configured to guide at least one cut in the bone block to form the bone graft, wherein the surgical method comprises:
- securing the bone block to the graft workstation, the bone block comprised of a distal tibia allograft;
- intraoperatively estimating an amount of bone loss of a bone using at least one of the plurality of sizing blocks;
- preparing the bone graft to a size and shape that corresponds to the at least one of the plurality of sizing blocks;
- selecting a first cutting block of the plurality of cutting blocks that corresponds to a size of the sizing block;
- connecting the first cutting block to the cutting jig of the graft workstation;
- and
- making a first cut in the bone block using the first cutting block,
- wherein making the first cut includes guiding a saw through a slot of the first cutting block.
A surgical method that employs a surgical instrumentation set comprising a graft workstation configured to receive a bone block, the graft workstation including a cutting jig movable relative to the bone block, a plurality of sizing blocks configured to estimate a size of a bone graft to be harvested from the bone block, and a plurality of cutting blocks interchangeably connectable to the cutting jig and each configured to guide at least one cut in the bone block to form the bone graft, wherein the surgical method comprises:
- securing the bone block to the graft workstation, the bone block comprised of a distal tibia allograft;
- intraoperatively estimating an amount of bone loss of a bone using at least one of the plurality of sizing blocks;
- and
- preparing the bone graft to a size and shape that corresponds to the at least one of the plurality of sizing blocks;
- forming holes in the bone graft;
- and
- fixating the bone graft to the bone by inserting fasteners through the holes and into the bone.
