Publication number: 20210401584Abstract: Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.Type: ApplicationFiled: October 1, 2019Publication date: December 30, 2021Applicant: Howmedia Osteonics Corp.Inventors: Shawn M. GARGAC, Austin Wyatt MUTCHLER, David R. STUMP, Alexander Paul WOLFE

Patent number: 10617405Abstract: Embodiments of the invention describe methods of implanting and setting an adjustable suture structure capable of maximizing and controlling the available range of motion in a defective joint. The adjustable suture structure can augment a joint repair following surgery or be used as a standalone construct. One embodiment involves completion of a standard ligament repair, followed by the implant of anchors to secure sutures between bone locations proximal to the native origin of the repaired ligaments. Each of the sutures is implanted with at least some slack. Once the sutures are secured, the first suture is alternatively tensioned and moved through a range of motion, followed by the same process in a second suture. The steps are performed iteratively until the range of motion is controlled or limited sufficiently to protect the repaired ligaments.Type: GrantFiled: January 27, 2017Date of Patent: April 14, 2020Assignee: Howmedia Osteonics Corp.Inventor: Ryan J.

Patent number: 9132209Abstract: A method for producing a wear resistant polyethylene medical implant includes forming a medical implant, such as an orthopedic implant, made at least partially of ultra high molecular weight polyethylene (UHMWPE). The polyethylene may be irradiated with gamma ray or e-beam radiation to form free radicals and then crosslinked to eliminate free radicals prior to exposure to oxygen. The so treated bearing surface of the crosslinked polyethylene is then coated with a photoinitiator. Thereafter the bearing material is photocrosslinked with ultra-violet (UV) radiation. The photocrosslinking process can also be applied to non-crosslink UHMWPE.Type: GrantFiled: May 7, 2010Date of Patent: September 15, 2015Assignee: Howmedia Osteonics Corp.Inventors: Shulin He, Zongtao Zhang, Keenan Michael Hanson, Shi-Shen Yau

Patent number: 8232327Abstract: Compositions and methods of their use to adhere a variety of materials together are disclosed herein. The compositions include at least tetra calcium phosphate, an effective amount of a compound that is structurally similar to phosphoserine, and can be mixed with an aqueous solution. The compositions provide adhesive and cohesive strength in both wet and dry environments and exhibit significant bond strength upon curing.Type: GrantFiled: November 12, 2009Date of Patent: July 31, 2012Assignee: Howmedia Osteonics CorpInventors: Venkat R. Garigapati, Brian J. Hess, Jon Ahola

Patent number: 7686533Abstract: A universal coupler for coupling multiple orthopedic instruments is disclosed. The universal coupler includes a body having a boss and an internal bore, a locking shaft having a first portion and a second portion, a trigger including a trigger bore, and a connection portion. The trigger is operable between a first position and a second position, where in the first position the first portion and boss are misaligned and in the second position the first portion and the boss are aligned.Type: GrantFiled: October 22, 2004Date of Patent: March 30, 2010Assignee: Howmedia Osteonics Corp.Inventor: Carlos E. Collazo

Patent number: 7678115Abstract: A method of preparing a knee joint for receiving a unicondylar knee implant includes preparing a first seating surface at a proximal end of a tibia, and providing a combination bur template and spacer block, the bur template having an upper end, a lower end and a curved surface extending between the upper and lower ends thereof that is adapted to conform to a femoral condyle of a femur and the spacer block extending from the lower end of the bur template and having top and bottom surfaces. The method includes flexing the knee joint so that the prepared first seating surface at the proximal end of the tibia opposes a posterior region of the femoral condyle and inserting the combination bur template and spacer block into the knee joint so that the top surface of the spacer block engages the posterior region of the femoral condyle and the bottom surface of the spacer block engages the first seating surface at the proximal end of the tibia.Type: GrantFiled: June 21, 2006Date of Patent: March 16, 2010Assignee: Howmedia Osteonics Corp.Inventors: Jerry D'Alessio, II, Carlos E. Collazo

Patent number: 7338499Abstract: Apparatus and method for interoperatively determining, during a trialing procedure conducted in connection with total hip arthroplasty at an implant site, a femoral neck length required in a femoral component to be engaged with an acetabular component of the prosthetic hip joint to be implanted at the implant site for establishing forces appropriate for proper articular engagement of the femoral component with the acetabular component, by moving a trial femoral head component and a trial femoral stem component relative to one another, while the trial femoral head component is engaged with an acetabular trial, to determine a measured distance corresponding to a trial distance between the trial femoral head component and the trial femoral stem component at which trial distance selected tensile forces are established in soft tissue at the implant site urging the trial femoral head component and the trial femoral stem component toward one another, the selected tensile forces corresponding to the forces appropriatType: GrantFiled: September 13, 2004Date of Patent: March 4, 2008Assignee: Howmedia Osteonics Corp.Inventors: John D. Kuczynski, John R. Simpson

Publication number: 20060200165Abstract: An acetabular shell or cup removal instrument is disclosed. The instrument includes a first end capable of being received within an acetabular cup and a cutting element pivotally attached. Cutting motion is provided to the instrument by a powered handpiece, so that the cutting element is capable of cutting a bone surface adjacent to an outer surface of the acetabular cup when the first end is within the acetabular cup.Type: ApplicationFiled: March 1, 2005Publication date: September 7, 2006Applicant: Howmedia Osteonics Corp.Inventor: Peter Tulkis
