Single-Injection Viscosupplementation

Genzyme Corporation announced on February 26, 2009, that the US Food and Drug Administration has granted marketing approval for Synvisc-One™ (hylan G-F 20), a product intended for the relief of pain associated with osteoarthritis of the knee. Synvisc-One is the only single-injection viscosupplement approved for the treatment of OA knee pain in the United States.

Synvisc-One is administered through a single intra-articular injection. It is an alternative treatment regimen to Genzyme’s Synvisc® (hylan G-F 20), a 3-injection viscosupplement approved in the United States in 1997 and in use worldwide for more than 16 years. Synvisc-One contains the same material and total treatment volume as Synvisc but provides the 6 mL of hylan G-F 20 in a single injection.

Synvisc-One is also approved in the European Union and a number of Asian and Latin American countries. Nearly 10,000 patients have been treated with Synvisc-One since it was first approved last year. Full prescribing information is available at www. synvisc-one.com .

Biotherapeutic Thermogels

BioSyntech, Inc., a biotechnology company developing biotherapeutic thermogels for regenerative medicine, announced that it will conduct an interim analysis of the available clinical data from 40 subjects who have completed their 12-month follow-up in the 80-subject trial for its cartilage repair device, BST-CarGel®. The company expects to have the results from this analysis available in the second quarter of 2009.

The ongoing, randomized BST-CarGel® pivotal trial compares the treatment of cartilage lesions using BST-CarGel® applied following microfracture to treatment with microfracture alone as a control. The trial enrolled 80 subjects aged 18 to 55 years with focal cartilage lesions less than 10 cm2 located on the femoral condyles of the knee. Subjects were further stratified by their lesion type, either acute (ie, traumatic) or chronic (ie, degenerative). The primary endpoint for this trial is cartilage repair at 12 months, defined by the quantity and quality of the repaired tissue as measured with quantitative magnetic resonance imaging. Secondary endpoints are safety and knee-related pain, stiffness, and function as measured using the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index questionnaire.

BioSyntech’s platform technology is a family of hydrogels called BST-Gel®, some of which are liquid at low temperature and solid at human body temperature. The company notes that these gels can be injected or applied to a specific local site and offer beneficial properties for the local repair of damaged tissue such as cartilage, bone, and chronic wounds and provide the benefit of avoiding invasive surgery.

Adult Stem Cell–Based Allograft

Orthofix International N.V. announces that the expected launch of Trinity® Evolution™ the next-generation adult stem cell–based allograft developed in collaboration with the Musculoskeletal Transplant Foundation (MTF), has been accelerated to May 1, 2009, two months ahead of schedule.

Trinity Evolution is an adult stem cell–based bone growth matrix designed to advance the surgical use of allografts by providing characteristics similar to an autograft used in spinal and orthopedic surgeries.

Acetabular Cup System Metal Liner Option

Smith & Nephew, Inc., Orthopaedic Reconstruction & Trauma, announced the introduction of a metal liner option for its R3 Acetabular System, an advanced multi-bearing acetabular cup system used in hip replacement and resurfacing procedures.

The metal liner was recently approved by the US Food and Drug Administration (FDA) for use with the Birmingham Hip™ Resurfacing (BHR™) System. Since March 2008, the R3 system has been fitted with cross-linked polyethylene (XLPE) liners for use in total hip replacement cases, and Smith & Nephew has received FDA approval of its ceramic liner option. The company notes that it is the only acetabular system available to surgeons that accommodates the major advanced bearing options, including metal-on-metal, ceramic-on-ceramic, cobalt chrome–on–cross-linked polyethylene (XLPE), and the company’s Oxinium™ Oxidized Zirconium–on–XLPE.

Smith & Nephew emphasizes that the multi-bearing cup, in addition to providing intraoperative flexibility for surgeons, provides solutions designed to reduce wear and the subsequent need for revision surgery. Its range of inserts accommodates larger head sizes and is optimized to help the R3 system achieve joint stability and a greater range of motion. By utilizing disposable trial liners and a single set of instruments for all bearings, the R3 Acetabular System aims to give surgeons simplicity in the operating room and confidence in a stable, multi-bearing system.

In tests, the R3 Acetabular System’s proprietary Stiktite™ porous coating demonstrated a higher coefficient of friction than trabecular metal on both cancellous and cortical bone, indicating the potential for superior scratch-fit feel and initial fixation. Additionally, Smith & Nephew notes that the R3 system is enhanced by a proprietary hard-bearing alignment guide—a thin plastic shield resembling a disposable coffee cup lid that enables surgeons to simply and accurately place a ceramic or metal liner into the shell during surgery. This technique is intended to reduce the risk of improper seating and malalignment.

Bioabsorbable Labral Tear Solution

Smith & Nephew’s Endoscopy Division has announced the launch of the Osteoraptor™ Anchor for repair in the hip and shoulder. During 2009, surgeons will perform an estimated 15,000 labral repair procedures in the hip joint and an estimated 185,000 procedures for the shoulder. Smith & Nephew Endoscopy Division notes that the new Osteoraptor Anchor is the first hip anchor to use polylactic acid hydroxyapatite (PLLA-HA) and that the key ingredient, hydroxyapatite (HA), is a mineral found naturally in bone. Studies have shown that the presence of HA increases the anchor’s strength and introduces chemicals that promote the formation of a strong bond between the anchor and the bone surface.1

The anchor is available in 2.3-mm and 2.9-mm sizes. The company notes that the Osteoraptor 2.3-mm Anchor for use in the hip is the smallest bio-absorbable hip anchor on the market. Typically, surgeons use multiple anchors to repair labral tears. The anchors’ size gives the surgeon the ability to place them more precisely within the tight confines of the joint space.

Based on surgeon feedback, the Osteoraptor Anchor system incorporates many features of the previously released Bioraptor™Anchor line—including the implant rib design and the instrumentation used to deliver the implant. Because they are molded from bioabsorbable PLLA-HA, the anchor is invisible on radiographs and does not distort images captured using magnetic resonance imaging.

Cream For Pain Relief

RZN Nutraceuticals has developed a medicated and clinically tested analgesic Arthri-Zen Relief Cream®. The company notes that a recent randomized, blinded study recruited 83 adults with physician-diagnosed arthritis, all of whom had had a history of daily arthritis pain for a minimum of 6 months. For 10 days, study subjects applied Arthri-Zen Relief Cream® to joint “hot spots” 3 times a day. They were evaluated by a clinician on the 1st day and again on the 10th day for conditions such as arthritis, inflammation, swelling, joint stiffness, muscle pain, and range of motion. Throughout the study, participants also kept daily pain diaries.

Overall, 63% of study subjects got relief from swelling, 93.8% experienced an increase in range of motion, 94.1% got relief from arthritis and inflammation, and a full 100% had relief from muscle pain and joint stiffness. All of the results were statistically significant.

RZN Nutraceuticals points out also that after 5 minutes, more than 25% of participants experienced 90%-100% relief from their pain. Another 41.3% got 70%-89% relief. And another 22.5% had 50%-69% relief. Arthri-Zen Relief Cream® provided relief from arthritis aches and pains for up to 8 hours.
Arthri-Zen Relief Cream® contains the OTC pain-relieving ingredient menthol, as well as RZN Nutraceuticals’ herbal formula including extracts of juniper, goldenrod, dandelion, meadowsweet, and willow bark. The ingredients are delivered in a base with moisturizing conditioners such as aloe, shea butter, avocado, and grape seed oil.

Arthri-Zen Relief Cream® is intended for use by those with arthritis and also by athletes to relieve the pain of backaches, sprains, bruises, strains, and stiffness. Currently, Arthri-Zen Relief Cream® is only available direct through the company’s Web site or by phone.
