Introducing DIP Joint Fusion with Functional Flexion
ArrowPhix is ExsoMed’s arrow-shaped screw for functional variable angle DIP fusions.
Late stage arthritis in phalangeal joints presents a variety of challenges for physicians. Although current treatment methods provide suitable outcomes, there is likelihood of producing a straight, distal interphalangeal joint fusions. These outcomes are not optimal.
Research has shown that when a patient’s distal interphalangeal joint is fused in a functional position, finger dexterity and grip strength improve over that of a patient with a straight, strength fusion.1 Physicians can achieve angled fusions by using K-wire fixation, however, the immobilization protocol can lead to several complications and varied results. While the utilization of compression screws provides reliable, strong repairs, it does not offer the additional benefit of functional flexion.
To address this unmet need, ExsoMed introduces ArrowPhix, an arrow-shaped implant for variable angle phalangeal fusions.
The system is provided sterile, where the implants are provided with a disposable instrument kit containing all necessary instrumentation to perform the case.
Why Use ArrowPhix?
Functional Fusion – arrow-shaped screw allows for variable angle fusion of the distal interphalangeal joint in a functional position
Stable Fixation – secure compression across the joint creates stability during bone fusion
Less Traumatic – Percutaneous insertion method minimizes surrounding tissue damage upon installation and avoids device prominence on fingertip
Early, Active Mobilization – Designed to facilitate early, active mobilization post operative protocols for accelerated healing and earlier return to work
- Small diameter for small joint arthrodesis with maximum bone-on-bone contact
- Tapered design facilitates both a functional fusion angle and compression across the joint
- Self-tapping screws for easy insertion
Indications for Use
The ArrowPhix compression screw is indicated for use in the surgical fixation of small bones, bone fragments, and osteotomies. The devices are not indicated for soft tissue fixation.
