Publication number: 20190150946Abstract: A surgical instrument for making femoral resections for seating a femoral implant on a distal femur, the instrument configured for orientation relative to an intramedullary rod. The instrument includes a medial distal cut guide having a cut guide portion, the cut guide portion having a cut slot therein for use in resecting a medial distal condyle of the femur. A medial distal cut paddle supports the medial distal cut guide. The medial distal cut paddle is configured to mount on the intramedullary rod to orient the medial distal cut slot substantially along an anterior-medial slope of the medial distal condyle when the medial distal cut paddle is mounted on the intramedullary rod to thereby define an anterior-medial approach for making a medial distal resection of the medial distal condyle.Type: ApplicationFiled: October 9, 2018Publication date: May 23, 2019Inventors: David R.

Patent number: 9220520Abstract: An anti-backout stylus comprising a stylus and a locking stylus holder. The locking stylus holder engages the stylus at a series of discrete positions during insertion of the stylus into the holder. The locking stylus holder prevents inadvertent backing out of the stylus by preventing the stylus from being withdrawn to a previous one of the discrete positions. The locking stylus holder can preferably be selectively disengaged from the stylus to allow for selective withdrawal of the stylus. Each engagement of one of the discrete positions by the locking stylus holder preferably indicates a femoral size. The discrete positions are preferably defined by detents formed on the stylus and a stop member on the locking stylus holder. The locking stylus holder can be provided on an anterior rough cut guide, with the anterior rough cut guide preferably mountable on an intramedullary rod.Type: GrantFiled: March 4, 2015Date of Patent: December 29, 2015Assignee: MicroPort Orthopedics Holdings, Inc.Inventors: David R.
