Design Rationale

Competitor 4-leg staple designs possess a flat bridge that doesn't generate compression, thus relying on the recovery of the legs alone for compression. The narrower legs also create stress concentrations at the weakest points of the staple under bending conditions, increasing the likelihood for implant failure once the patient begins weight-bearing. Peer-reviewed studies report these competitor staples breaking in up to 11% of patients.

In contrast, the DynaClip Delta's 4-leg design features a broad, low-profile bridge that distributes stresses across the bridge away from the legs (see image to right), and allows for compression to be generated through the bridge.
