Arthroscopic devices, systems, and methods of use
View Patent ↗Arthroscopic devices adapted for minimally invasive procedures, such as bone augmentations and reconstructive surgery, are provided. The arthroscopic devices include a drill guide adapted for efficiently and accurately positioning pilot holes and surgical instrumentation relative to the bone; a surgical cable, such as an elastomeric surgical cable, adapted for applying a compressive force across the bone fragments after the surgical repair to promote healing; and a tensioner and crimping device for applying tension to the surgical cable and securing the surgical cable in place. A surgical procedure is also disclosed where a cerclage is applied arthroscopically by passing a member such as an elastomeric ribbon through the glenoid and a bone graft, where the member is tensioned and fixed into place to hold the bone graft in firm contact with the glenoid to facilitate healing.
1 . A method of performing an arthroscopic bone augmentation surgery, comprising:
drilling a pilot hole into a bone in need of augmentation surgery, wherein the drilling is performed from a first side to a second side;
passing a first end of a surgical cable through the pilot hole from the first side to the second side and into a graft;
securing a first crimping member to the first end of the surgical cable on the first side, wherein the first crimping member is secured to an outer surface of the bone;
passing a second end of the surgical cable through a tensioning and crimping device and into engagement with a tensioning mechanism;
tensioning the surgical cable using the tensioning mechanism to a setting sufficient to apply a compressive force to the bone and the graft;
while maintaining the compressive force, actuating movement of a securing member carried within the tensioning and crimping device toward a second crimping member positioned at a distal end of the tensioning and crimping device;
engaging the securing member with the second crimping member, wherein the securing member comprises a plurality of barbs configured to engage with a plurality of corresponding grooves on the second crimping member; and
releasing the securing member from the tensioning and crimping device upon engagement with the second crimping member on the second side to preserve the applied compressive force, wherein the second crimping member and engaged securing member are secured to an outer surface of the graft.
2 . The method of claim 1 , wherein the first side is a posterior side and the second side is an anterior side.
3 . The method of claim 1 , wherein the step of tensioning further comprises tensioning the surgical cable to about 400 N to 800 N to provide a continuous active compressive force across the bone and the graft.
4 . The method of claim 1 , wherein the bone in need of augmentation surgery is a glenoid.
5 . The method of claim 1 , further comprising creating a posterior portal for insertion of a posterior cannula and an anterior portal for insertion of an anterior cannula.
6 . The method of claim 1 , wherein the first end of the surgical cable is passed through the pilot hole without forming a loop.
7 . The method of claim 1 , wherein the drilling step comprises drilling a single pilot hole into the bone in need of augmentation surgery.
8 . The method of claim 1 , wherein the first crimping member sits flush against the outer surface of the bone and the second crimping member sits flush against the outer surface of the graft.
9 . The method of claim 1 , wherein the second crimping member and engaged securing member sit flush against the outer surface of the graft.
