2 Arthroscopic Shoulder Instability Repair Using the Curved Guide and Anchor Delivery System As described by: Roy Majors, MD OrthoCarolina, Charlotte, North Carolina Arthroscopic capsulorrhaphy, labral repairs, and SLAP repairs are some of the most demanding procedures facing the surgeon. Anchor placement is possibly the most important part of the procedure. Improper anchor placement can lead to anchor pull-out, joint damage, or non-anatomic tissue repair. Currently available straight anchor guides can make it difficult for the surgeon to accurately place anchors. Smith & Nephew has developed a curved guide and anchor delivery system that gives the surgeon the tools necessary to consistently place anchors with an optimized trajectory in various positions on the glenoid rim 1. This system allows for the delivery of Smith & Nephew s current BIORAPTOR 2.3 PK or OSTEORAPTOR 2.3 PLLA/HA Suture Anchors which have been successfully used in thousands of cases.

3 INSTRUMENTATION The curved guides are reusable, stainless steel, cannulated, curved shafts with ergonomic handles designed to aid in alignment and improved anchor placement during drilling and anchor insertion. Insertion of the curved guides is aided by the flexible obturator a reusable, stainless steel, pliable shaft with a blunt tip and handle which has been designed to occlude soft tissue during insertion. The flexible drill used with the curved guides is made of stainless steel and includes a fluted bit designed to optimally create the required pilot hole. These instruments are designed for use only with the Smith & Nephew BIORAPTOR Curved 2.3 PK and OSTEORAPTOR Curved 2.3 PLLA/HA Suture Anchors, preloaded on flexible inserters with high-strength ULTRABRAID Suture. fishmouth tip crown tip PATIENT PREPARATION AND PORTAL PLACEMENT The surgeon can easily use the curved guide and anchor delivery system in both the beach chair and lateral decubitus positions. 1. Drape the shoulder so that the surgeon has unrestricted access to the shoulder. 2. Establish a standard posterior portal at the soft spot. Typically, the posterior portal is used for arthroscopic visualization. 3. Establish the anterior-superior portal (for the non-operative cannula) in the rotator cuff interval. 4. Establish the anterior-inferior portal (for the operative cannula) as close to the superior edge of the subscapularis tendon as possible. SHOULDER TECHNIQUE GUIDE Rev. A 3

4 STEP 1 STEP 3 PREPARATION OF THE TISSUE Prepare tissue in the manner to which the surgeon is accustomed. Ensure the capsulolabral structures are well-mobilized to allow for an anatomic repair or adequate advancement of tissue, if needed. Debride all soft tissue from the glenoid neck at the rim level and below using the Smith & Nephew INCISOR Blade, 4.5 mm, concave, curved. If needed, use the Smith & Nephew 4.5 mm Shielded Burr to roughen the bone to promote tissue healing. STEP 2 DRILLING THE HOLE Maintain firm pressure on the curved guide in both a forward and rotational direction. Place the flexible drill bit into the curved guide. Begin running the drill as the drill bit passes down the curved guide to decrease any resistance of the drill bit passing around the bend of the guide. When the drill tip engages bone, the auger design pulls the tip forward until it is fully seated. While removing the drill bit, continue to run the drill in forward mode to decrease resistance of the drill bit against the guide bend as it exits. It is best to perform insertion/drilling/extraction in a single motion, maintaining firm pressure on the curved guide in both a forward and rotational direction with the drill constantly running in forward mode. Note: Guide alignment change while drilling may cause drill bit breakage. Maintaining guide alignment throughout drilling is required to ensure drill bit integrity. STEP 4 INTRODUCTION AND POSITIONING OF THE GUIDE ON THE GLENOID Place the curved guide through the anterior-inferior 8.0 mm x 72 mm CLEAR-TRAC Flexible Cannula for anchor placement (operative cannula). Ensure that the curved guide moves freely in the cannula. Turn the guide so that its curve matches the curve of the humeral head. Move the curved guide tip to the desired position on the glenoid rim. Place the tip of the curved guide (convex side) on the glenoid face side of the rim. Rotate the curved guide onto the face of the glenoid to the desired position by turning the handle of the curved guide. Maintain gentle forward pressure on the curved guide to prevent it from slipping off the glenoid. Once the tip of the curved guide is on the glenoid face, rotate the tip to create a perpendicular angle to the glenoid face. INSERTING THE ANCHOR Align and place the inserter into the curved guide, maintaining pressure in both a forward and rotational direction. Ensure that the V on the anchor inserter handle aligns with the laser marks on the guide before tapping the anchor into the bone. Begin to gently tap the anchor handle to decrease any resistance of the anchor as it passes down the curved guide. Once the anchor engages in bone, continue to tap the handle of the inserter until it is completely seated on the top of the curved guide. 4 SHOULDER TECHNIQUE GUIDE Rev. A

5 STEP 5 RELEASING THE ANCHOR Once the anchor is completely inserted, release the sutures from the handle by pulling back the lime green, spring-loaded collar. Draw the handle back from the top of the curved guide. Tip: A gentle, back-and-forth twisting motion can be helpful in removing the anchor inserter from the curved guide. Using an ELITE PREMIUM Suture Loop Vertical Grasper down the non-operative cannula, reach through the monofilament loop, grasp a limb of ULTRABRAID Suture and pull it through the loop and out of the non-operative cannula. STEP 6 Remove the suture shuttle from the operative cannula with the suture limb passed through the loop. PASSING THE SUTURE THROUGH THE LABRUM Insert the ACCU-PASS Suture Shuttle down the operative cannula and through the labrum and capsule to be reattached/shifted. Both limbs of suture are now in the operative cannula. Advance the monofilament loop into the joint space by rolling both of the side wheels of the suture shuttle in a downward motion (do not remove the suture shuttle at this point).

6 STEP 7 TIE THE KNOTS Using desired knot-tying technique, tie the limbs of ULTRABRAID Suture. STEP 8 CUT THE SUTURE LIMBS Using the Smith & Nephew suture cutter, cut the suture limbs to the desired length. STEP 9 FINAL REPAIR Repeat steps 1 8, as necessary, in order to complete the repair. 6 SHOULDER TECHNIQUE GUIDE Rev. A

7 TECHNIQUE PEARLS 1. When drilling, ensure the drill guide is secure on the bone to avoid inadvertent slippage of the drill. 2. Use a CLEAR-TRAC COMPLETE Threaded Cannula with a minimum diameter of 8.5 mm or an 8.0 mm x 72 mm CLEAR-TRAC FLEXIBLE Threaded Cannula with the curved delivery system. POSTOPERATIVE CARE* Use an arm sling for two to four weeks. Begin protected range of motion keeping elbow in front of the plain of the chest. Avoid shoulder extension or excessive external rotation for the first six weeks. Lifting, pushing, and pulling should be limited during the first six weeks. * The views and opinions expressed for postoperative care are solely those of the surgeon(s) and do not reflect the views of Smith & Nephew, Inc.
