Instrumentation and technique for sizing a bone reconstruction graft
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.
1. 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 plurality of cutting blocks include a first cutting block having a first slot configured to make a vertical cut in said bone graft and a second slot configured to make an angled cut in said bone graft.
2. The surgical instrumentation set as recited in claim 1 , wherein said bone graft is a distal tibia allograft.
3. The surgical instrumentation set as recited in claim 1 , wherein said graft workstation includes a first graft holding post and a second graft holding post.
4. The surgical instrumentation set as recited in claim 3 , wherein said first graft holding post and said second graft holding post are slidable within a first slot of a base plate of said graft workstation and said cutting jig is slidable within a second slot of said base plate.
5. The surgical instrumentation set as recited in claim 3 , wherein said first graft holding post includes a spiked post configured to receive said bone block.
6. The surgical instrumentation set as recited in claim 1 , wherein said plurality of cutting blocks include a second cutting block configured to make a horizontal cut in said bone graft.
7. The surgical instrumentation set as recited in claim 6 , wherein said plurality of cutting blocks include a third cutting block configured to make additional vertical cuts in said bone graft.
8. 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 configured to retrieve said bone graft from said bone block.
9. 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; and
a parallel pin guide, a guide wire, and a drill configured to aid in preparing said bone graft.
