Image-guided surgery is an effective tool for the achievement of correct screw placement in C1-C2 transarticular screw fixation procedures. The procedure remains technically demanding.

FiberWire is a popular suture in flexor tendon repair that allows for early mobilization, but its poor knot-holding properties have raised concerns over the potential effects on tendon healing and strength. We examined how the number of knot throws affects the 2 mm gap force, ultimate tensile strength, and mode of failure in a four-strand cruciate locked tendon repair in porcine flexor tendons in order to elucidate the optimal number of suture throws. There was no effect on the 2 mm gap force with increasing knot throws, but there was a significant increase in ultimate tensile strength. A minimum of six-knot throws prevents unravelling, whereas five out of 10 of repairs unravelled with less than six throws.
