Method and apparatus for reconstructing a hip joint, including the provision and use of a novel arthroscopic debridement template for assisting in the treatment of cam-type femoroacetabular impingement
View Patent ↗Apparatus for use in debriding a bone, said apparatus comprising: an arthroscopic debridement template comprising a body reconfigurable between (i) a first configuration having a first profile and comprising an arc matching the desired curvature of the bone after debridement, and (ii) a second configuration having a second profile, wherein said second profile is smaller than said first profile.
1. A method for debriding a bone, said method comprising:
providing an apparatus comprising:
an arthroscopic debridement template comprising at least two markers for disposition within the bone, wherein said at least two markers each comprise a body discernable from bone;
identifying a bony protrusion on a bone to be debrided;
implanting said at least two markers within the bone that is to be debrided, wherein said at least two markers are implanted at locations which demarcate at least one of (i) the perimeter of the bony protrusion which is to be removed from the bone to be debrided, and (ii) the depth of the amount of the bony protrusion which is to be removed from the bone to be debrided; and
debriding the bony protrusion using said arthroscopic debridement template for guidance.
2. A method according to claim 1 wherein said at least two markers each comprise a rod.
3. A method according to claim 1 wherein said at least two markers are each formed out of a radiopaque material.
4. A method according to claim 1 wherein at least one of the at least two markers comprises a biocompatible material.
5. A method according to claim 1 wherein implanting said at least two markers comprises driving said at least two markers directly into the bone.
6. A method according to claim 1 wherein implanting said at least two markers comprises drilling at least two holes into the bone and inserting said at least two markers into the holes.
7. A method according to claim 1 wherein at least one of the at least two markers comprises surface features for enhancing engagement with the bone.
8. A method according to claim 1 wherein at least one of the at least two markers comprises plastic.
9. A method according to claim 1 wherein at least one of the at least two markers comprises stainless steel.
10. A method according to claim 1 wherein the bony protrusion is on an outer surface of the bone, wherein the at least two markers are implanted into the outer surface of the bone in a first direction, and further wherein the bony protrusion is debrided by approaching the bony protrusion from the first direction.
