The new Mpower™ system merges large bone power with the size and design of a small bone handpiece, to create the most versatile system on the market today. Mpower handpieces generate more than 140 in./lbs. of torque and can be used in the most demanding large bone surgery, such as a total hip arthroplasty. But these handpieces also produce up to 1,500 rpm and are just as suitable for delicate hand and foot surgery.
