Ascension Orthopedics, Inc. announces FDA approval to market the TITAN™ Modular Total Shoulder System. This system redefines modularity by providing multiple surgical solutions for shoulder arthroplasty with one implant system. The TITAN Modular Total Shoulder System offers a bone-preserving option for patients needing total or hemi shoulder arthroplasty. The modularity of the system allows the surgeon to independently select distal stems and proximal bodies that best match the patient’s anatomy and bone quality.

Cayenne Medical Inc. has received FDA clearance for the iFix(TM) Interference Screw System for use in bone-tendon-bone ACL reconstruction procedures. These are the first FDA approved screws to hit the market that are made from polyetheretherketone (PEEK) plastic, which is radiolucent and highly biocompatible and has superior biomechanical strength. PEEK is a completely bio-inert material and, hence, screws made from this material do not result in foreign body reactions in patients.

Biomedical engineering researchers at the Queensland University of Technology (QUT) are working on developing a computer modeling program that would allow surgeons to simulate scoliosis surgery. This would enable surgeons to determine the most effective procedure before entering the operation theater. Professor Clayton Adam, a member of QUT’s Institute of Health and Biomedical Innovation (IHBI), said, “Spine surgery is one of the most complicated and painstaking operations because surgeons cannot afford to damage the delicate spinal cord.”

Glucosamine sulfate, a dietary supplement, is not more effective than a placebo in relieving pain for patients of osteoarthritis of the hip, according to a study led by Rianna Rozendaal and published in the Annals of Internal Medicine. The randomized two-year study was conducted on 222 people suffering from mild to moderate osteoarthritis of the hip, with half the group partaking 1,500 milligrams of glucosamine daily and the other half taking a placebo. The researchers concluded that the rate of improvement was insignificant between patients receiving glucosamine sulfate and those receiving the placebo. Critics said, however, that the study may have produced different results if it had been conducted for an additional year or if patients with more severe osteoarthritis had been studied.

Medtronic Inc. has received FDA approval for RestoreULTRA, an implantable neurostimulation system device for the treatment of chronic, troublesome pain in the back and leg. Patients can adjust the stimulations produced by the rechargeable device according to fluctuations in pain through a remote control, apart from directing the stimulations at a specific point in the spinal cord. The company plans to make the device available in the U.S. by the end of February.

Despite the past few years’ product recalls and safety controversies, The Freedonia Group, Inc. estimates the demand for implantable devices will increase 9.3% annually in the US. Sales will reach $43.6 billion in 2011.

Driving the increased demand are shortcomings in existing drug therapies. In their place is a resurgence of cardiac and orthopedic implants; estimated to grow in demand at 9% and 8.8%, respectively. Cardiac implants represent the top seller of implantable medical devices, due to the prevalence of heart disease in the United States, and the extremely life-threatening nature of the disease itself.

Voluven, an intravenous synthetic starch solution, has received FDA approval for use in surgery as a blood volume expander. Blood volume expanders are used to quickly restore some of the blood volume lost during surgery so that remaining red blood cells can continue to deliver oxygen to the body’s tissues. Voluven is manufactured by Fresenius Kabi, a German company.
