THE MITEK MINI G2 SUTURE ANCHOR - BIOMECHANICAL ANALYSIS OF USE IN THE HAND

We inserted 36 Mitek Mini G2 suture anchors (Mitek Surgical Products, Westwood, MA) into various sites of 14 fresh cadaver hands. A single-s trand O-Ethibond suture (Ethicon, Sommerville, NJ) was threaded throug h each anchor, inserted into bone, and loaded to failure. In all cases , either the anchor pulled out (11 of 36) or the suture broke (25 of 3 6). No anchors fractured. We also measured the breaking strength of si x types of suture material (without anchors) commonly used by hand sur geons; all failed at much lower loads than those generated in our anch or pullout model. We conclude that the Mitek Mini G2 suture anchor pos sesses sufficient pullout strength for tendon and ligament fixation in the hand, including the distal phalanx.
