Stryker Corporation (Stryker), incorporated in 1946, is a medical technology company with a range of products in orthopaedics and a presence in other medical specialties. The Company’s products include implants used in joint replacement, trauma, craniomaxillofacial and spinal surgeries; biologics; surgical, neurologic, ear, nose and throat and interventional pain equipment; endoscopic, surgical navigation, communications and digital imaging systems; as well as patient handling and emergency medical equipment. The Company operates in two business segments: Orthopaedic Implants and MedSurg Equipment. The Orthopaedic Implants segment sells orthopaedic reconstructive (hip, knee and shoulder), trauma, craniomaxillofacial and spinal implant systems; bone cement; and the bone growth factor OP-1. The MedSurg Equipment segment sells surgical equipment; surgical navigation systems; endoscopic, communications and digital imaging systems; as well as patient handling and emergency medical equipment.
Orthopaedic Implants are designed and manufactured by Stryker Orthopaedics, Stryker Osteosynthesis, Stryker Spine and Stryker Biotech and consist of such products as implants used in joint replacement, trauma, craniomaxillofacial and spinal surgeries; bone cement; and the bone growth factor OP-1. Artificial joints are made of cobalt chromium, titanium alloys, ceramics or ultrahigh molecular weight polyethylene and are implanted in patients whose natural joints have been damaged by arthritis, osteoporosis, other diseases or injury. The Company’s OP-1 bone growth factor induces the formation of new bone when implanted into bone, is composed of recombinant human OP-1 and a bioresorbable collagen matrix.
The Company’s reconstructive implants are suited to minimally invasive surgery (MIS) procedures that are intended to reduce soft-tissue damage and pain while hastening return to function. The Company supports surgeons with technology, procedural development and specialized instrumentation as they develop MIS techniques. The Company’s surgical navigation systems are used in MIS procedures to improve the accuracy of measurements and to position the implant. The Company’s Triathlon Total Knee Minimally Invasive Instrumentation is designed to complement the invasive total knee procedure pioneered by an orthopaedic surgeon. The Triathlon Partial Knee Resurfacing (PKR) unicompartmental knee system and the Avon Patellofemoral Joint are resurfacing, bone-conserving designs that are used to treat disease isolated to one compartment of the knee.
Stryker’s product portfolio includes products, such as OP-1, a recombinant version of a signaling protein with multiple tissue regeneration properties and TissueMend, a single-layer acellular collagen matrix. It also includes HydroSet, a bone substitute technology; BoneSource BVF, an osteoconductive bone substitute with biocompatibility and mechanical stability, and BoneSave, a granules-based alternative to bone grafting.
Through Stryker Orthopaedics, the Company offers a range of hip implant systems for the global reconstructive market including primary (or first-time) and revision (to repair or improve a previous replacement) hip systems, as well as hip systems. During the year ended December 31, 2007, the Company began selling the Cormet Hip Resurfacing System in the United States pursuant to a 10-year marketing and distribution agreement with Corin Group PLC. These products represent a less invasive, joint preserving hip resurfacing option for younger patients with the potential for improved stability and range of motion. In hip resurfacing procedures, very little bone is removed from the femoral head, the femoral neck is preserved and the femoral canal is spared.
The Company offers a system of cementless stems, cemented stems and acetabular cups for each of its primary hip implant technologies, including ABG, Partnership, Secur-Fit, Omnifit, Accolade, Exeter and Trident hip systems. These systems, along with associated surgical instrumentation, are designed to provide personalized solutions based on the patient’s anatomy while streamlining the implant procedure to improve surgical efficiencies. Each of these systems includes a portfolio of primary stem options based on multiple fixation philosophies, including anatomic, fit/fill, taper wedge and double-tapered designs. In addition, acetabular systems, including the Trident and ABG Acetabular systems provide a range of options for achieving initial and long term fixation. During the year ended December 31, 2008 the Company introduced the Tritanium Primary acetabular system. This system provides an advanced fixation technology offering a pure titanium matrix designed to improve bone ingrowth. Stryker has also introduced the X3 polyethylene. X3 polyethylene is the Company’s crosslinked polyethylene, which features a level of strength and wears reduction in both hip and knee replacements.
The Company offers a number of products designed to meet the needs of revision hip procedures, including Restoration, Restoration Modular, Trident Tritanium Revision, and Dall-Miles each of which provides surgeons with the options necessary to address revision surgery challenges. The Restoration Modular Revision Hip System offers surgeons performing revision surgeries flexibility in treating complex hip stem revisions and restoring patient biomechanics. The Restoration Modular Revision Hip System also takes advantage of Stryker’s clinical history with hydroxylapatite (HA), a naturally occurring calcium phosphate material that demonstrates a high level of biocompatibility due to its resemblance to bone, by incorporating PureFix HA coating on many components. The Restoration Modular Revision Hip System improves the Company’s existing Restoration HA and Restoration plasma spray (PS) monolithic revision systems. The Restoration System is complemented by the Trident Tritanium Acetabular Cup, a biologically inspired, commercially pure titanium ingrowth surface designed to provide solid initial fixation and promote bone ingrowth. Coupled with the availability of the Dall-Miles System for trochanteric reattachment and cerclage fixation, Stryker’s revision portfolio offers solutions to address challenges encountered in revision surgery.
The Company’s CentPillar Hip System offers a range of motion and an invasive technique preferred by Japanese surgeons for their patients. In 2007 the Company introduced CentPillar TMZF to the Japanese market.
Knee replacement surgery is a procedure intended to replace damaged articular bone surfaces in the knee joint often due to arthritis. The components used frequently are a femoral component, a tibial tray, a tibial bearing insert, and a patella bearing. Knee replacement surgeries also include primary procedures and revision procedures. Primary procedures tend to focus on the knee’s articular surfaces, whereas revision procedures can include simple replacement of one or more previously implanted devices, implantation of different devices to accommodate certain instabilities in the joint or larger reconstruction of the joint in severe cases.
The Company offers three knee implant systems: Triathlon, Scorpio, and Global Modular Replacement System (GMRS) systems. These implant systems were complemented in 2008 with the introduction of the Triathlon PKR unicompartmental knee system and the continued rollout of the Triathlon Total Stabilizer (TS) revision knee system and the Company’s X3 bearing technology for both Triathlon and Scorpio. The Triathlon PKR unicompartmental knee system was designed to resurface specific areas of the knee while leaving other healthy areas intact. It combines surgical instrumentation specifically designed for minimally invasive surgery with the single radius articular design and X3 advanced bearing material.
The Triathlon Knee System represents the Company’s evolutionary design that has been developed to more closely reproduce natural knee motion and is designed to provide mobility with stability through more than 150 degrees of flexion. The Triathlon Primary Knee system gives surgeons versatile instrumentation options that provide both accuracy and efficiency in a minimally-invasive approach, as well as options for treating varying degrees of instability in the knee. In 2007 the Company introduced the Triathlon condylar stabilizing (CS) version designed to provide extra stability where the posterior cruciate ligament is either weak or missing. The Triathlon cruciate-retaining (CR) version allows for retention of a functioning posterior cruciate ligament. The Triathlon posteriorly stabilized (PS) version provides a mechanical substitution for the posterior cruciate ligament, for an even greater degree of stability. The instrumentation for Triathlon is designed to improve operating room efficiency through a streamlined, integrated system providing options and flexibility to meet surgeons’ different preferences and multiple surgical techniques. In 2007, Stryker introduced the Precision instrument kit, specifically designed to improve surgical efficiencies through a sterile-packed disposable set of instruments, complimenting the existing Triathlon kits.
In 2007, the Company released the Triathlon TS revision knee system consisting of a comprehensive line of implants and instrumentation. Triathlon TS is designed to provide the surgeon options to deal with varying degrees of instability and bone loss in the knee, caused by either severe disease or revision of previous implants. It is also designed to provide the patient the ability to achieve the performance of a primary knee replacement in a revision application, again leveraging Stryker’s single radius design philosophy. Triathlon TS can be used with the X3 tibial insert, making it the only revision knee system on the market that offers cross-linked bearing material.
The Scorpio knee implant system is based on the Company’s design of a single articular radius based on the epicondylar axis of the knee. This approach addresses clinical issues, such as improved patient rehabilitation and mid-flexion stability, through the patella-femoral moment arm and a single anterior-posterior radius. The Scorpio system provides a range of options for the surgeon and patient in treatment of knee arthritis and stability. The Scorpio NRG provides an evolution in kinematic benefits, including increased rotational allowance and an articulating design enabling deeper flexion. In 2007, the Scorpio NRG with X3 advanced bearing technology was launched. This new version of the Scorpio NRG is designed to lower wear rates compared with standard inserts. The Scorpio System is supported by the X-Celerate instrumentation system, which was designed to provide intraoperative flexibility and precision, as well as an approach to total knee replacement surgery. Additionally, the Scorpio TS knee revision system provides surgeons the ability to address greater degrees of instability and bone loss in both primary and revision knee scenarios.
The GMRS knee implant system offers a solution for bone loss in oncology, trauma and revision surgery patients. GMRS has tibial and femoral components, including a total femur, and a modular rotating hinge knee. The system utilizes both titanium and cobalt chrome alloys for strength and lightness of weight, together with the superior flexibility of the hinge.
The Company markets other joint replacement products, principally shoulder and elbow implants and related instruments, under the Stryker brand name. The Solar Total Shoulder System was designed to address the common arthritic disorders affecting the shoulder, such as rheumatoid arthritis, osteoarthritis, posttraumatic arthritis and avascular necrosis. In cases of disease involving both the humeral head and the glenoid cavity with an intact rotator cuff, optimal pain relief and function may be achieved with total shoulder arthroplasty. In cases of cuff arthropathy, the Solar Bipolar, which incorporates the patented bipolar locking mechanism that is also used in the Company’s hip implants, was designed to fill the joint space and provide two articulating surfaces for better joint mechanics and pain relief. In 2007 the Company introduced the ReUnion Shoulder fracture system of implants and instrumentation. The ReUnion System utilizes a trial system to simplify the reconstruction of the shoulder during fracture surgery. The ReUnion’s body and fenestration enable the surgeon to use a range of suture techniques and improves healing. The Solar Total Elbow complements products offered for upper extremity procedures. The semiconstrained design and modular components address types of patient anatomy.
Simplex bone cement, a material used in cemented joint replacements, is used as bone cement in the world. The Company manufactures and provides several variations of Simplex bone cement to meet patient and clinical needs, including non-antibiotic and antibiotic versions.
Through Stryker Osteosynthesis, the Company develops, manufactures and markets its trauma extremities and deformities systems.
