UCL and RCL Tears of the Thumb

Arthrex has developed the Thumb Metacarpophalangeal (MCP) Joint Ulnar Collateral Ligament (UCL) Repair using either a 2.5 mm PushLock® Knotless Suture Anchor, a Micro/Mini BioComposite SutureTak®, a Micro/Mini FT Corkscrew® or FASTak™ anchors. Reconstruction of a chronic tear is achieved by utilizing two 3 mm x 8 mm Bio-Tenodesis™ Screw.

2.5 mm PushLock® Thumb Collateral Ligament Repair
Using #2-0 or #0 suture the torn ulnar collateral ligament of the thumb is sutured. The 2.5 mm PushLock® uses a PEEK eyelet to place the sutures at the bottom of a drill hole, allowing the surgeon to tension precisely by hand and lock the sutures in place by impacting the tak portion of the anchor. Both the high strength radiolucent PEEK and the absorbable PLLA 2.5 mm PushLock optimize tissue tension and fixation without knot tying. The final repair is tensioned to the surgeon's preference and remains completely knotless allowing for less irritation with minimal overlying soft tissue.

For more information on this surgical technique, please see the resources section.
Corkscrew® Thumb Collateral Ligament Repair
A K-wire pre-drill is used to create a bone socket for the anchor. The anchor is screwed into the bone socket until the anchor is fully seated. The anchor handle is removed exposing two FiberWire sutures and diamond point needles. The needles are advanced through the soft tissue to accomplish the desired stitch. Once completed the needles are removed and the sutures are tied using the surgeons preferred sliding or static knot.
DX SwiveLock® SL Anchor Thumb Collateral Ligament Reconstruction
Ulnar collateral ligament (UCL) tears of the thumb are common injuries. When the tear results in pain and instability, surgical repair offers a predictably successful outcome. Augmenting the reconstruction with SutureTape to create an InternalBrace™ ligament augmentation results in a strong construct that allows for early motion and limited postoperative immobilization.1
SutureTak® Thumb Collateral Ligament Repair
Utilizing a drill or punch, a bone socket is created for the anchor. The drill or punch is removed and the implant is inserted through into the bone socket. The anchor is gently impacted until it is fully seated. The anchor handle is removed exposing the 2 FiberWire sutures and tapered needles. The needles are advanced through the soft tissue to accomplish the desired stitch. Once the sutures are passed, the needles are removed and the sutures are tied using the surgeon's preferred sliding or static knot.
Thumb Collateral Ligament Reconstruction With Tenodesis Screws and InternalBrace™ Ligament Augmentation
InternalBrace™ ligament augmentation used with tenodesis screws or SwiveLock® anchors allows earlier joint motion and faster return to activity.1 The 2.5 mm × 6 mm and 3 mm × 8 mm tenodesis screws can be used in conjunction with SutureTape to reconstruct and augment the thumb UCL ligament.
