Non-Union in the Upper Extremities

Non-Union Treatment in the Shoulder, Arm, Wrist, and Fingers: A Multicentre Retrospective Study Comparing Conventional Treatment with the Human Allogeneic Cortical Bone Screw (Shark Screw®).

What it’s about:
This multicentre, retrospective study compared conventional non-union treatment using metal hardware (n=11) with the human allogeneic cortical bone screw - Shark Screw® (n= 30)

Key Findings
Union rate: 96.7% with Shark Screw® vs. 72.7% with conventional treatment
Time to union: 10.8 weeks with Shark Screw® vs. 39 weeks conventional
Return to work: 11 weeks with Shark Screw® vs. 25 weeks conventional
Complication rate: 3.4% with Shark Screw® vs. 36% conventional
Hardware removal: 0% with Shark Screw® vs 64% conventional

Why it matters
The study shows that Shark Screw® offers not only strong mechanical stability but also true biological integration resulting in faster healing, fewer complications, and no need for hardware removal.

This research further validates Shark Screw® as a reliable option for non-union treatment in the shoulder, arm, wrist, and fingers.
