Patent number: 11147691Abstract: A method of performing joint arthroplasty includes accessing a surface on a bone and supporting a stop with the accessed surface. The method includes positioning an instrument at least partially within the stop, the instrument having a body and a punch, the punch including a portion thereof having a shape similar to a shape of a stem of an implant, and rotating the stop with respect to the accessed surface based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the accessed surface at a first orientation. The method further includes moving the body axially with respect to the stop to form a cavity in the bone with the punch at the first rotational orientation, the formed cavity having a shape similar to the stem of the implant, and implanting the stem of the implant into the cavity.Type: GrantFiled: November 19, 2019Date of Patent: October 19, 2021Assignee: DePuy Synthes Products, Inc.Inventors: Jack F.

Publication number: 20200113511Abstract: The disclosure is directed to a system and methods for dynamic diagnosis of musculoskeletal conditions. The methods include monitoring at least one body part of a subject with at least one sensor, the at least one sensor configured to detect motions of the at least one body part of the subject, the at least one sensor comprising a Micro Electro Mechanical System (MEMS) sensor. The at least one sensor transmits kinematic data to a signature-comparing device. The methods include obtaining composite signatures of the subject based on the kinematic data, the composite signatures comprising at least one motion signature. The methods also include comparing the composite signatures of the subject to a normal composite signature to determine whether a difference between the composite signatures of the subject and the normal composite signatures is larger than a pre-determined threshold.Type: ApplicationFiled: October 11, 2019Publication date: April 16, 2020Inventors: Lanny Leo Johnson, Gerald R.
