The Anser Clavicle Pin is a unique technology dedicated specifically to the surgical management of mid-shaft clavicle fractures. Historically treated non-operatively, many studies in the last decades report superior outcomes when managed surgically. An increase of 705% of clavicle fracture surgeries in a 12-year time period has been described. Clavicle fractures are one of the most commonly fractured bones in the human body with an incidence of 60 per 100,000 person years. This means almost 650,000 clavicle fractures occur yearly in the US and EU alone. The majority (75-80%) of these fractures occur at the middle third of the clavicle.
Currently, the most common surgical treatment of the mid-shaft clavicle fracture is by means of plates and screws. Disadvantages of this option include large incisions, infection, hardware failure, sensory nerve damage and hardware irritation requiring removal during a second surgery. Intramedullary (IM) devices are devices placed inside the bone, and are also used in the management of clavicle fractures. These too have their specific array of disadvantages such as hardware prominence, protrusion, telescoping, migration, wound breakdown and an almost 100% need for removal during a secondary intervention.
Rigid and bulky intramedullary systems such as the Sonoma Crx, Rockwood Pin, Hagie Pin and Knowles Pin are no longer used or available. Acumed’s portfolio includes the Dual-Trak Clavicle screw which can only be used for a very specific subset of clavicle fractures. The Titanium Elastic Nail (Synthes/Stryker), is a non-clavicle specific device which is used and subject to the before-mentioned complications. All of these disadvantages lead to decreased outcomes for the patient and increased healthcare costs and societal burden.
The Anser Clavicle Pin has the potential to disrupt the current market and become the most used device in the near future. Its design allows for an intramedullary re-alignment of the fractured clavicle. The Anser Clavicle Pin is flexible so it can follow the s-shaped intramedullary canal and rigid enough to withstand the forces across the clavicle and keep it at length. It is anchored on both sides of the fracture aiming to maintain the reduction and preventing implant migration and secondary shortening. To prevent loss of fixation and by aiming for secondary bone healing the technology allows for rotational freedom of the fracture elements within its design.
The surgical technique is minimally invasive, partially cannulated and targets great cosmetic and patient satisfaction with a minimum risk of complications. There is minimal hardware prominence, which helps to reduce the need for removal of hardware.
