New study shows Integrum’s OPRA™ Implant System to be safe and durable method to treat thumb amputees

Integrum, a leading provider of innovative solutions for bone anchored prosthetics, is pleased to announce that the Journal of the American Academy of Orthopaedic Surgeons (JAAOS) has published details of a study featuring Integrum’s OPRA™ implant system to enable osseointegrated thumb reconstruction. The study results, published in the January 2019 issue, indicate that the OPRA™ Implant System is a safe and durable method to treat patients with thumb amputations.

The retrospective single center study, based on preoperative and postoperative data collected from 13 thumb amputees, concludes that the “treatment of thumb amputees using bone-anchored percutaneous prostheses with the osseointegration technique seems to be a safe, durable method with excellent short- and medium-long follow-up results. Using the latest design (after 2005), there is a 100% cumulative success rate, up to 10 years of follow-up. Although the patient population is limited, the osseointegrated reconstruction of thumbs is shown to offer a valuable psychological, functional, and rehabilitative potential in daily life activities for patients.”
