Abstract
A patella fracture fixation system includes a peripheral rim bone plate that is configured to be implanted along a parapatellar lateral approach. The bone plate can configured to minimize disruption of blood supply to the patella. The bone plate can be augmented with a Krackow suture pattern to assist in stabilization of a comminuted inferior pole.
Claims15
A method of treating a fractured patella, the method comprising the steps of:
- creating a longitudinal skin incision along a lateral border of the patella;
- inserting a bone plate through the incision and around at least a portion of the patella, such that 1) first and second parallel rows of bone fixation holes of a base of the bone plate face a lateral portion of a circumferential rim of the patella, an inferior pole of the patella, and a superior pole of the patella, and 2) an outer portion of the bone plate that extends from the base faces an anterior surface of the patella;
- driving a lateral fixation element through the bone plate into the circumferential rim substantially along a medial direction;
- driving second fixation elements through the bone plate and into respective ones of the inferior pole and the superior pole;
- and
- driving an anterior fixation element through the outer portion and into the anterior surface of the patella.
