Recently, focusing onShoulder Arthroplasty SolutionsMedical Device CompanyShoulder InnovationsAnnouncementCompleted $40 million (approximately RMB 290 million)The E-round financing,The funds will mainly be used to advance the commercialization of its InSet total shoulder and reverse shoulder replacement systems, support corporate activities, and develop new products.

This round of financing was led by the American venture capital firm US Venture Partners, with participation from existing investors Gilde Healthcare Partners, Aperture Venture Partners, Gilmartin Capital, Sectoral Asset Management, and Arboretum Ventures.

# Research and Development Background

In traditional total shoulder arthroplasty, the glenoid is typically placed at the top of the bone surface, where it is prone to stress from the patient's arm-lifting or arm-swinging movements. This can cause the humerus to move up and down, rotate, and slide back and forth due to reactive forces, eventually leading to glenoid loosening. This affects limb mobility and may even worsen the patient’s condition—a phenomenon known as the "rocking horse" effect.To address this major issue leading to the failure of shoulder arthroplasty, Shoulder Innovations has developed an embedded glenoid fixation technology.

The founder of the company, Dr. Stephen Gunther, comes from a family of medical professionals. After obtaining his medical degree at Dartmouth Medical School, he was exposed to engineering labs and polyethylene research while teaching at the University of California, San Francisco, which led him to focus on the study of joint replacement surgery.After discovering the issue of glenoid instability in shoulder arthroplasty, he proposed the InSet glenoid solution with innovative thinking.

Most of the company's team members have experience and background related to orthopedics. Robert Ball, CEO and Executive Chairman, previously served as the Global Vice President of R&D at Tornier NV, driving the market development of medical device technology. Vice President Don Running has also held senior executive positions at several orthopedic companies, including Johnson & Johnson. Additionally, the clinical team includes professors, directors, and surgeons from various university medical schools, providing professional support for product development.

# Core Products

InSet™ TSA Series

Glenoid loosening remains a leading cause of total shoulder arthroplasty (TSA) failure.Traditional glenoid designs are typically placed only on the bone surface, which may lead to instability and gradually loosen over time.

InSet™ Glenoid is specifically designed to address this challenge, focusing on mechanical stability and long-term durability.A glenoid implant with a longer lifespan and better performance in a broader patient population.

InSet™ Glenoid：Designed to be embedded within the hardened bone edge, providing five implant diameter sizes and two thicknesses to accommodate various glenoid sizes.
InSet™ PLUS Augmented Glenoid：Designed to correct defects in the joint surface, available in 5-degree or 10-degree options. The flat back design ensures 100% posterior coverage. Utilizing standard surgical techniques, it allows for correction after reaming without additional preparation, reducing the risk of lift-off and migration.

InSet™ Glenoid adopts an innovative design that places the implant within a pocket of hardened bone, a technique that has been proven to significantly reduce mechanical stress at the bone-implant interface.

Finite Element Analysis (FEA) shows that the "teeter-totter" stress (considered one of the main factors leading to implant loosening) is reduced by 87%.

InSet™ Reverse Shoulder Arthroplasty

The InSet™ Reverse System offers an innovative solution for managing complex shoulder conditions while preserving biomechanical integrity. The system optimizes rotational capability through its lateralized glenoid and humeral construct, helping surgeons maximize the use of the patient’s remaining native anatomy to position the greater tuberosity, thereby maximizing postoperative function.

Titanium Alloy Humerus Stem: Designed to be Flatter or More Compact, without creating a noticeable bulge at the shoulder, reducing postoperative discomfort while avoiding unnecessary pressure or abrasion on the surrounding soft tissues (such as the rotator cuff).
Remove the neck structure,This can reduce the amount of bone resection around the humeral head.Better preservation of the humeral head bone provides a better foundation for postoperative shoulder joint stability and functional recovery.
InSet 95：Using twoDesign of Fin-like Structure, better control of the rotational stability of the implant during the surgical procedure, ensuring it remains in the appropriate position after implantation and reducing issues such as displacement caused by rotational instability. The suture hole is designed with a notch to better accommodate the fixation method of the suture, providing a more stable suturing effect.

ProVoyance™ Shoulder Arthroplasty Planning Software

ProVoyance™ Shoulder Arthroplasty Planning Software offers extensive customization options, providing detailed preoperative insights and a user-friendly planning environment that surgeons can adjust according to their individual preferences and needs.

The core technology of ProVoyance Shoulder is a cutting-edge artificial intelligence/machine learning (AI/ML) technology capable of generating more refined and accurate 3D bone models from CT images, better reflecting the true anatomical structure of the shoulder bones.

The process from CT imaging to 3D bone reconstruction can be highly automated, reducing the steps and time required for manual intervention and improving work efficiency. Doctors can more intuitively understand the relationship between the lesion site and the surrounding bones, allowing for the development of more precise treatment plans.

# Multiple Financings

Since its establishment, Shoulder Innovations has attracted significant attention from investors with its innovative technology in the field of shoulder arthroplasty and has successfully completed multiple rounds of financing, providing solid financial support for the company's continued development.

In 2017, the company completed$1.6 millionSeries A Equity Financing.This round of financing was led by Michigan Angel Fund, with active participation from Wakestream Ventures, Genesis Innovation Group, and cultivate (MD) among other institutions. The funds will be mainly used to accelerate the development process of new products and expand the inventory of InSet Glenoid technology, laying a foundation for the company's subsequent development.

Subsequently,The company has gained approximately$2.5 millionAdditional A-round Financing, further consolidating its position in the market.

In November 2020, Shoulder Innovations announced the completion of$21.6 millionEquity financing.This round of financing was led by US Venture Partners and Lightstone Ventures, with participation from Alumni Venture Partners, Wakestream Ventures and other institutions. The injection of funds provides strong momentum for the company's continued growth and commercialization efforts, helping SHOULDER INNOVATIONS, INC. to continuously expand its market share in the shoulder joint replacement field.

In March 2023, the company reached an important development milestone and announced the completion of an oversubscribed funding round.$42 millionD round of financing.This financing was led by Gilde Healthcare Partners, a professional transatlantic healthcare investor. Existing investors US Venture Partners, Lightstone Ventures, and cultivate (MD) Accelerator Capital fund continued their support, while new investors Gilmartin Capital and Aperture Venture Partners also joined. The additional subscription not only provided the company with sufficient funds but also enabled Shoulder Innovations to accelerate the expansion of its commercial and distribution operations, better maintain and optimize its product platform, and further enhance its competitiveness in the industry.

In August 2023, Shoulder Innovations announced a successful partnership with Trinity Capital, securing$45 millionDebt financing.This injection of funds provides strong support for the company's further development in the field of shoulder joint replacement implants, enabling it to maintain its leading position in technological innovation and market expansion.
