Fig. 1From: A comparison of EFECE systems with tension band wiring for patella fracture fixation in cadaversThe EFECE implant locking mechanism is applied with the help of balls in the cone-shaped gloves. In forward movement to compress the fractured fragments across the K-wire, the balls move back to the base of the cone and release the K-wire. When pulled back, the balls move to the narrow part of the cone and lock the K-wireBack to article page
