Patient-Matched Primary Reversed

2021: Start of implantation in endoprosthesis of shoulder joint

On January 20, 2022, Stryker announced that its Patient-Matched Primary Reversed glenoid was first used in shoulder prosthetics. The company develops custom implants with Blueprint 3D planning software.

Stryker developed its primary reversible glenoid, and also released a limited number of Patient-Matched Primary Reversed to the market. The Blueprint program from Stryker allows the surgeon to virtually position and perform the creation of a patient-friendly implant. After completion of work, Blueprint generates an order for the manufacture of a glenoid support plate and instruments for a particular patient, after which the surgeon receives sterile devices and implants the support plate using a non-boring technique that preserves bone.

Our relentless pursuit of innovation in shoulder endoprosthesis continues. With Blueprint 3D Planning software and the market-leading Tornier Perform anatomical and reversible glenoids, the Tornier Perform shoulder leg offers clinical solutions for both the simplest and most complex cases. The device will provide our customers with autonomy that is not anywhere else on the market, "said Tim Lanier, Stryker's vice president and CEO of upper limbs.

According to the company's press release, the glenoid, selected for the patient, gives surgeons the opportunity to adjust the implant to the shape of their native glenoid, unique to the anatomy of each patient. The system of glenoids selected for the patient improves the effectiveness of the operating room, requiring fewer surgical steps and without scanning the glenoid bone. The document notes that Dr. Jay Keener of St. Louis, USA completed the first implant on January 13, 2022. It will be discussed in a presentation at the 2022 Advanced Shoulder Arthroplasty meeting on January 21, 2022 in Snowberd, USA.

The glenoid cavity, also called the "rosettes," is located on the lateral corner of the scapula, directed to the sides and forward and joins with the head of the humerus. The surface of the cavity is covered with cartilage in a fresh state, and its edges, slightly raised, attach to the fibrous cartilage structure, the glenoid lip, which deepens the cavity. This cartilage is very prone to rupture. In rupture, this is most often known as SLAP lesion, which is usually caused by repeated shoulder movements. Damage to the tissues surrounding the shoulder cavity can be caused by acute trauma or repeated movements of the shoulder.^[1]
