Variable threaded pitch Cannulated Comes with a profile drill Are tapered on the outer diameter Headless design Answer: Are tapered on the outer diameter Q: True or False: a 3.5 mini compression FT screws schieves a statically significant higher maximum push-out when compared to an acumed acutrak 2 mini screw and a synthes 3.0mm Hebert screw. This may lead to a better long term stability and less likely screw backout/ Answer: false Q: When using a 3.5 mm DX SwiveLock® SL anchor in the metacarpal head for reconstruction of the thumb UCL using SutureTape and a palmaris longus autograft what size drill should be used? 3.2 mm 3.0 mm 3.5 mm 3.7 mm Answer: 3.5 mm Q: Before placing the second SwiveLock® anchor for a thumb UCL IB repair, the thumb should be placed in: Neutral 60 degrees of extension 30 degrees of flexion 60 degrees of flexion Answer: 30 degrees of flexion Q: What size graft should be used for a thumb UCL reconstruction when using the 3.5 DX SwiveLock® SL anchor? 4 mm 2 mm 5 mm 3.5 mm Answer: 2 mm Q: True or False: When small bone is encountered on the proximal phalanx when performing a thumb UCL repair, a Mini PushLock® anchor may be substituted for a 3.5 SwiveLock® anchor. Answer: True Q: The anchor position in the base of the proximal phalanx for a thumb UCL repair/reconstruction should be placed? Slightly more volar than midline Slightly more dorsal than midline Central On the articular surface Answer: Slightly more volar than midline Q: Which of the following statements regarding the thumb is CORRECT? In MCP flexion the proper UCL resists valgus force In MCP flexion the proper UCL resists varus force In MCP extension the accessory UCL resists varus force In MCP flexion the accessory UCL resists valgus force Answer: In MCP flexion the proper UCL resists valgus force Q: What is the length of the anchor body and fork-tipped eyelet in the 3.5 mm DX SwiveLock® SL anchor? 4 mm 4.5 mm 4 inches 8.5 mm Answer: 8.5 mm Q: True or False: Use of fluoroscopy should be recommended when placing the 3.2mm spade-tip pin in the calcaneus for an FHL tendon transfer.
