X-Porous Tibial Tuberosity Advancement (TTA): A Next-Generation Solution in Canine Orthopedics

Cruciate ligament rupture is one of the most common orthopedic conditions in dogs, often resulting in pain, instability, and lameness. Among the surgical techniques available to treat this injury, Tibial Tuberosity Advancement (TTA) has become a leading method due to its biomechanical advantages and long-term success rates. At Ad Maiora, we’ve taken this concept further with the development of X-Porous Tibial Tuberosity Advancement (TTA)—an innovative solution that enhances both implant integration and surgical outcomes.

The X-Porous TTA system is designed to correct cranial cruciate ligament (CCL) deficiency by altering the dynamics of the stifle joint. Instead of replacing the ligament, the TTA technique shifts the patellar ligament to a more functional angle by advancing the tibial tuberosity. This mechanical change neutralizes the shear forces in the joint during weight-bearing, thereby restoring stability and improving mobility. What sets the X-Porous system apart is the unique porous titanium structure of the implant, engineered to encourage superior bone in-growth and long-term biological fixation.

Traditional TTA implants, while effective, often rely solely on mechanical stability and screw fixation. The X-Porous design introduces a next-generation material technology that not only stabilizes the tibial tuberosity but also integrates with the surrounding bone over time. The interconnected porous structure closely mimics cancellous bone, allowing osteoblasts to colonize the implant surface and create a stronger, more natural bond. This improves overall stability, reduces the risk of implant migration or loosening, and supports faster and more reliable healing.

The X-Porous Tibial Tuberosity Advancement (TTA) system by Ad Maiora is also designed with surgical efficiency in mind. With anatomically contoured implants, simplified instrumentation, and multiple size options, the system allows for precision in planning and execution. Surgeons can choose from a range of cage sizes and plates to suit the individual anatomy of each canine patient, whether for small breeds or large, active dogs. The modular design ensures optimal fit and reduces intraoperative adjustment time, contributing to smoother procedures and improved outcomes.

Beyond the mechanical and biological advantages, the use of porous implants aligns with the broader trend toward biologically friendly orthopedic solutions. In veterinary practice, where postoperative recovery and owner satisfaction are critical, offering a durable, integration-focused implant gives clinics a competitive edge and pet owners greater confidence in their dog's recovery process.

At Ad Maiora, we are proud to lead the way in veterinary orthopedic innovation. Our X-Porous TTA system reflects our commitment to combining advanced materials science with practical surgical design. By rethinking the way implants interact with the body, we’re helping veterinary professionals achieve better outcomes with fewer complications—and ultimately, giving dogs a quicker return to pain-free mobility.

Piastra di bloccaggio a croce piccola: Osteosintesi bloccata con placca di avanzamento Ad Maiora

In ortopedia veterinaria, una stabilizzazione efficace delle fratture è fondamentale per un recupero di successo. L'osteosintesi con placche, una tecnica chirurgica all'avanguardia, svolge un ruolo fondamentale nel raggiungimento di questo obiettivo. La chiave del suo successo risiede nell'uso di placche di bloccaggio, che offrono un maggiore supporto biomeccanico fissando con precisione i frammenti ossei e resistendo ai movimenti di rotazione. Questo metodo è particolarmente utile per trattare le fratture in aree che sopportano carichi significativi, come gli arti, e garantisce un allineamento corretto durante la guarigione.  La flessibilità delle placche di bloccaggio consente una personalizzazione ottimale per adattarsi ai singoli tipi di frattura, rendendo questa tecnica indispensabile per i veterinari che eseguono la stabilizzazione delle fratture. Ad Maiora fornisce la placca di bloccaggio CPS-100 con 13 fori accuratamente posizionati, un dispositivo all'avanguar...

When to Choose an External Fixator: Clinical Applications in Veterinary Surgery

Image
External fixation systems are essential in veterinary orthopedics, providing stability and support in treating complex fractures. These systems are particularly valuable in cases where internal fixation is not feasible due to infection risks, severe bone fragmentation, or the need for progressive alignment. However, not all external fixators are the same. The most advanced external fixation solutions are designed with specific features that make them particularly suitable for complex clinical scenarios in small and large animals. Indications for the Use of External Fixat i o n in Veterinary Surgery External fixation is often the optimal choice for managing open fractures, highly comminuted fractures, and fractures in high-risk areas, such as those near joints or the pelvis. These injuries are particularly prone to infections or may be too unstable for internal fixation. In such cases, external fixation provides a stable structure, preventing further damage to soft tissues and reducing...
