MedShape Inc., Atlanta, announces the full commercial launch of the DynaClip bone fixation system, which is based on superelastic Nitinol technology. The DynaClip represents the next generation in bone stapling by providing both dynamic compression and reliable durability to withstand the demanding loading conditions in the foot and ankle. The system is also provided sterile with consolidated all-disposable instrumentation to improve efficiency during surgery.
Nitinol staples have become an attractive surgical offering for foot and ankle surgeons due to their ease of use and ability to continuously apply compression across the fusion site post-surgery. However, current staple designs have either a thin wire shape or a wide bridge with narrow legs that create stress concentrations at the weakest points of the staple. These localized stresses increase the likelihood for implant failure once the patient begins weight-bearing.
To address these limitations, the DynaClip’s patented design features a broad bridge with a continuous low-profile and thickened legs that evenly distribute stresses across the bridge and away from the implant corners. These features provide higher bending strength and the ability to resist breaking longer under cyclic fatigue compared with competitor staples.
The DynaClip staple also comes pre-loaded on a disposable inserter that includes a built-in tamp and features a “Quick-Slide Release” mechanism for a fast, simple delivery method. In the event the surgeon is not satisfied with the position in bone, the DynaClip can be removed and re-positioned using a Re-load Tool. The DynaClip is provided in nine different sizes, including multiple leg lengths, in order to accommodate all patient anatomy in the forefoot, midfoot, and hindfoot while still maximizing dynamic compression.
The DynaClip represents MedShape’s second product offering to feature the company’s superelastic Nitinol technology. In 2013, the company launched the DynaNail TTC Fusion System, the only hindfoot intramedullary nailing system that can maintain post-operative compression and provide immediate dynamization, thus revolutionizing how surgeons could treat challenging patient populations with severe hindfoot deformities and arthritis.
