LRTI Procedure Using the Arthrex Tenodesis Screw for Thumb Basilar Arthritis

This cadaveric surgical video will demonstrate the Arthrex CMC implant system using the four by ten tenodesis screw for ligament reconstruction at the base of the thumb. This procedure clinically is performed under regional anesthesia and tourniquet control. A 3 to 4 centimeter longitudinal incision is made over the dorsal midline of the thumb, centered on the trapezium. Blunt dissection is used to identify and preserve branches of the dorsal sensory radial nerve, as well as the radial artery. The first dorsal compartment tendon sheath over the length of the incision is incised and tendons retracted. A longitudinal capsulotomy is then made in the locations of the CMC and scaphoid. Trapezium trapezoid joints are confirmed. The Arthrex CMC removal tool, which aids in manipulation of the trapezium, is shown here. The trapezium is then subperiosteal dissected of all soft tissue attachments and excised. A rongeur or osteotomy can also be used depending upon surgeon preference. Care is taken to taken to preserve the CRx tendon modally. The trapezius base is then examined and any remaining bone fragments or osteophytes are removed. The CRx tendon is located and removed. In this cadaver specimen, the entire FCR is harvested. However, a 4 to 5 centimeter graft can be harvested by applying tension distally and transecting. The most proximal aspect of the FCR near the scaphoid trapezium trapezoid joint. This eliminates the need for a second incision to harvest the FCR. The tendon graft should measure approximately four millimeters across for ideal fixation with the four millimeters tenodesis screw. Trim the tendon graft to appropriate size if needed. The LRT kit comes with all the instrumentation and implants needed to complete the procedure. A guide pin. A four millimeters cannulated drill. A QuickPass tendon shuttle which simplifies tendon passage. And a four by ten tenodesis screw with driver. Two-o suture with needle and a flexible nitinol loop are also included as alternative tendon passing options. The guidewire is introduced into the base of the first metacarpal, starting in the midline dorsally one centimeter distal to the articular margin, angling obliquely in a volar and proximal direction to exit the palmar cortex just distal to the articular margin in the area of the volar oblique ligament. Insertion. The four millimeter cannulated drill is then passed over the guidewire. The QuickPass tendon shuttle mesh end can be inverted to allow for easy insertion of the tendon graft, as shown. The tendon shuttle is then used to pass the tendon through the drill tunnel. While applying enough traction to the FCR to take the slack out of the tendon. Manual pressure is applied to the first metacarpal base toward the second metacarpal base, and the four by ten millimeter tenodesis screw is inserted into the drill hole for an interference fit. Burying the screw within the metacarpal. Any remaining CRx tendon can be placed into the trapezius space. Or the tendon can be cut flush at the base of the metacarpal. Final construct shows resistance to subluxation.
