DynaClip Delta
DynaClip Delta™
Biomechanical Performance Driven Staple System for 1st MTP Fusion
Specifically designed for 1st MTP fusion, the DynaClip Delta™ Bone Fixation System demonstrates exceptional biomechanical performance. Its unique 4-leg, triangular configuration offers enhanced compression and rotational stability, rendering it the viable choice for robust NiTiNOL staples in 1st MTP fusion procedures.

Features & Benefits
Enhanced Durability: DynaClip Delta's design places stress across the bridge, away from the legs, improving resistance to failure post-surgery.
Maximized Compression: Increased bridge curvature allows for compression generation through bridge, not just the legs.
Low-Profile: Tapered, low-profile bridge designed to minimize prominence and patient irritation.
Design Rationale
Competitor four-legged bone staples feature a flat bridge that fails to generate compression, leaving compression solely reliant on the legs' recovery. The narrower legs exacerbate stress concentrations at the staple's weakest junctures when subjected to bending forces, heightening the risk of implant failure once the patient initiates weight-bearing activities. Peer-reviewed studies have documented instances of these competitor staples breaking in as many as 11% of patients. 1
In contrast, the DynaClip Delta™ Bone Fixation System demonstrated 4x less permanent plantar gapping than a plate with a crossing screw construct.2 The unique 4-leg staple design places stresses across the bridge, away from the legs, improving resistance to failure post 1st MTP fusion when patients initiate weight-bearing.
