New Allograft Talocalcaneal Ligament Introduced

Arthrosurface, Inc. recently introduced a new allograft talocalcaneal ligament for use in adult and teen patients who suffer from talocalcaneal instability, peritalar subluxation and other injuries that result in foot and ankle instability. The new allograft is brand named SpiralUp TCL Allograft System.

A healthy talocalcaneal ligament is essential to foot function by providing a layer of strong and flexible connective tissue. But when the doctor needs a replacement talocalcaneal ligament, there is now an allograft to meet that need—the SpiralUp TCL Allograft.

“The foot is the foundation of the body. When it or the gait cycle is compromised, an imbalance can be created throughout the body leading to strain and excessive wear of joints,” said Steve Ek company CEO in a statement.

“The SpiralUp TCL Allograft System represents yet another early intervention product in our portfolio that is designed to address the root cause of these types of problems and mitigate other cumulative effects throughout the musculoskeletal chain.”

Harold Schoenhaus, DPM, FACFAS, professor of The Temple University School of Podiatric Medicine, told OTW that patients who have ligamentous laxity, compensatory abnormal function of the subtalar and midtarsal joint, patients who toe-in, and those who have a tight Achilles are more prone to talocalcaneal instability and peritalar subluxation. Patients with congenital calcaneal valgus, knock-knee, posterior tibial dysfunction and those who have traumatic subluxation of the subtalar joint are all also more prone to talocalcaneal instability and peritalar subluxation.

On what makes the SpiralUp TCL Allograft System stand out from current standard of care, he said, “The biggest difference is that there is currently no procedure available that re-establishes the ligamentous integrity of the subtalar joint. The SpiralUp TCL Allograft is now the only system available that does this.”

“The relocation of subtalar instability requires ligamentous integrity to maintain the normal anatomic alignment of the talus to the calcaneus. By maintaining the subtalar stability, the midtarsal joint, primarily the talonavicular, relocation provides stability within the arch. Other procedures have attempted to block the motion between the talus and calcaneus which does not address the ligamentous instability. The SpiralUp TCL Allograft addresses all of these issues.”

Schoenhaus added, “Talocalcaneal instability and peritalar subluxation are progressive conditions with far-reaching symptoms and a vast patient population. After treating patients for over 45 years with these types of problems and symptoms, I envision the SpiralUp TCL Allograft System could be the most effective solution to alleviating these problems. It is intended to stabilize the subtalar and midtarsal joints while simultaneously addressing conditions such as arch, leg, knee and lower back discomfort.”
