Publication number: 20210093332Abstract: A minimally invasive hip arthroplasty technique involves intramedullary insertion of an elongate femoral broach into a femur. The broach has a superior lateromedial transverse bore. A reaming rod is then located through the transverse bore and the neck of the femur. A cutting head is coupled to a distal end of the reaming rod via an incision. An orthogonal drive arm of an arthroplasty jig may also be inserted behind the cutting head to press the cutting head to ream the acetabulum while the reaming rod rotates the cutting head.Type: ApplicationFiled: December 21, 2018Publication date: April 1, 2021Inventor: Peter Walker

Publication number: 20200375615Abstract: There is provided herein and improved anterior cruciate ligament reconstruction technique which comprises drilling a guide wire straight through a tibial passage and then at an angle from an ACL insertion point straight through a femoral passage. A reamer is then attached to a proximal end of the guidewire. The reamer has a distal cutting head, a distal flexible shaft, a proximal cutting head and a proximal flexible shaft. The proximal cutting head has a greater diameter than that of the distal cutting head. The reamer is drilled to follow the guidewire until the distal cutting head passes through the femoral cortex. The reamer is then retrieved at a proximal end thereof, thereby having created a larger diameter medial passage portion and a smaller diameter lateral passage portion within the femoral passage in a single pass, thereafter being ready for insertion of a graft, including by endobutton fixation.Type: ApplicationFiled: February 14, 2019Publication date: December 3, 2020Inventor: Peter Walker

Publication number: 20200151726Abstract: Embodiments of the invention are directed to systems and methods for utilizing a cache to store historical transaction data. A predictive model may be trained to identify particular identifiers associated with historical data that is likely to be utilized on a particular date and/or within a particular time period. The historical data corresponding to these identifiers may be stored in a cache of the processing computer. Subsequently, an authorization request message may be received that includes an identifier. The processing computer may utilize the identifier to retrieve historical transaction data from the cache. The retrieved data may be utilized to perform any suitable operation. By predicting the data that will be needed to perform these operations, and preemptively store such data in a cache, the latency associated with subsequent processing may be reduced and the performance of the system as a whole improved.Type: ApplicationFiled: November 13, 2018Publication date: May 14, 2020Inventors: Hongqin Song, Yu GU, Dan WANG, Peter WALKER
