Trauma Devices

This category includes to nails, screws, plates and other products surgically implanted in the fracture site. These products are used in surgery to treat femoral neck fractures, most often suffered by the elderly, and other fractures from auto-related and other accidents.

We have a leading domestic share in the trauma devices market, with their sales accounting for approximately 40% of overall sales (market size: approximately ¥45.0 billion). We provide trauma devices supplied by DePuy Orthopaedics Inc. (former DePuy Ace), one of the world’s foremost manufacturers in this field, operating under the umbrella of the Johnson & Johnson group. Our trauma devices are used in medical institutions nationwide. We provide various materials satisfying the needs of virtually any patients and applicable to any emergency surgery. We also pioneered the use of titanium alloy devices, which are light, strong and biocompatible, in the field of orthopedics on the Japanese market.

Joint Prostheses

This category includes to products, made from artificial materials, that replace natural joints and restore functions severely damaged or lost due to disease or injury. While leveraging its sales channel to orthopedic surgeons built over the years, Japan MDM has been trying to complete portfolio to meet their needs. Joint prostheses comprise the strategic product that Japan MDM seeks to gain a firmer foothold with in the orthopedic market. It is worth approximately ¥93.0 billion, nearly twice as large as that for trauma devices. Having grown steadily, joint prostheses now account for nearly 38% of Japan MDM's net sales. In 1994, Japan MDM confirmed its move into the field of joint prostheses with the acquisition of Ortho Development Corporation, a joint prosthesis manufacture in Salt Lake City, Utah. After establishing a development and manufacturing framework, Japan MDM launched Ortho Development Corporation Bipolar System, hip prosthesis in Japan in 1996. This milestone was followed by launch of the Balanced Knee System for knee prosthesis in 2001. In 2002, Ortho Development Corporation began the full-scale sale of joint prostheses in the U.S., a market with a scale that dwarfs that of Japan.

For joint replacements today, there is greater demand for different product sizes and variations to better match individual patient anatomy. Surgeons too have grown more explicit in what they expect from these products. Japan MDM, with the development and manufacturing framework firmly in place, has the powerful competitive edge to meet these challenges rapidly and in-depth, and to provide stable supply of joint prostheses over the long term.

Spinal Fixation Devices

Spinal fractures, osteoporosis and other diseases can cause spinal instability, which may lead to severe pain and other neurological symptoms. One treatment option is to fix this spinal instability directly through corrective surgery. Spinal fixation devices are essential for this procedure. While the market for these devices, at around ¥28.5 billion, is roughly a third of that for trauma devices, it is the fastest growing sector of the orthopedics field. Japan MDM has just started to sell these devices in 2000, so they still account for a mere 10% of net sales. That figure, however, is expected to increase as Ortho Development Corporation keeps development of new products, and Ortho Development Corporation's domestic sales framework is bolstered and the market continues to expand.

In November 2009, we concluded a joint sales agreement with Zimmer K.K. to further strengthen our product lineup and promote joint sales, thus expanding our market share at the same time.

Artificial Bone Fillers

Bioceramic bone paste, an artificial bone filler for the treatment of bone fractures, tumors and other defects, is prepared by mixing a powder and solidifying solution to form a paste or putty-like substance that is applied to bone fractures or other defects. The paste then solidifies inside the body and becomes hydroxyapatite (HAP), an inorganic structural element of bone. This process stimulates regeneration compatible with surrounding bones. The bone paste Japan MDM will offer will be supplied by NGK Spark Plug Co., Ltd. Looking ahead, the bone-filler market is expected to grow due to a higher incidence of osteoporosis in Japan's aging population. The introduction of bone paste will enhance Japan MDM's product offering in the orthopedic field and promises to create synergies with other products. Japan MDM plans to begin sales of bone paste in November 2005.
