“…Numerous studies have demonstrated the safety and efficacy of nitinol compression staples used for in TMT fusion procedures. 3,9,14,15,21,23 TMT fusions performed using nitinol compression staples have fusion rates near 90%, which is comparable to the reported values for conventional fixation. 18 The fusion rate in this study, 89.7% is in agreement with the current available evidence.…”

“…It is reported that compression staples generate a significantly greater compression force across a stimulated osteotomy compared to mechanical staples, and resist permanent deformation, fully recovering their shape following loading.

Background: Tarsometatarsal (TMT) arthrodesis is commonly performed in the management of midfoot arthritis, trauma, or deformity. The purpose of this study was to collect aggregate data (demographic, surgical, and perioperative outcomes) on patients who previously had a TMT fusion with BME compression staples. Methods: Sixty-six patients underwent TMT fusion with BME compression staples. Outcomes included demographics, surgical information, the Veterans Rand VR-12 Health Survey, Foot and Ankle Ability Measure (FAAM), visual analog scale (VAS), Revised-Foot Function Index (FFI-R), Ankle Osteoarthritis Scale (AOS), patient satisfaction survey scores, radiographic fusion rate, level of pain reduction, and complications. Sixty-six patients (68 feet) were analyzed (59 females) with an average age of 64 years (range, 18-83). The mean latest follow-up was 35.9 (range, 6-56.6 months). Results: The average surgical time was 38.1±14.3 minutes (range, 11-75). All outcomes improved significantly ( P < .001) from preoperative to latest follow-up except for the VR-12 Mental and Physical score. The average time to fusion determined by radiographs was 8.4 weeks (range, 6.1-46.1 weeks). Wound complications were not seen. Indications for subsequent surgeries (26.5%, 18/68 feet) in this current study included pain (n = 14), broken staples, and nonunion (n = 3). Conclusions: The fusion rate in this study, 89.7%, was similar to values reported in the literature. The patient satisfaction score of 81.9 at latest follow-up is consistent with patient satisfaction for other methods of fusion. Level of Evidence: Level IV, retrospective case series.

“…Composed of nearly equal atomic percentages of nickel and titanium, nitinol is a biologically safe metal alloy first developed by Naval scientists in 1959. [1][2][3] Nitinol stands for Nickel Titanium Naval Ordinance Laboratory and was discovered by William J. Buehler and Frederick Wang while trying to improve a missile nose cone. Nitinol's 2 unique properties of shape memory and super elasticity make it well suited to multiple applications, including orthopedic implants.…”

“…Peer-reviewed clinical research of nitinol-based implants in foot and ankle surgery suggests early promising results with potentially faster and higher rates of bony union. 2,[6][7][8] While nitinol staples have emerged as the most commonly used nitinol-based implant in foot and ankle surgery, 2,8,9 non −nitinol-based screw and screw-plate combinations remain the most commonly used implants overall. Most commercially available implant systems are manufactured with stainless steel or titanium which lack inherent compressive properties.…”

Fracture fixation and joint arthrodesis are among the most common procedures in foot and ankle surgery. Successful outcomes rely on union between bony interfaces. With a thin and relatively delicate soft tissue envelope, the foot and ankle require implants and techniques that generate compression to achieve bony union while respecting local soft tissue anatomy. Recently, orthopedic implants comprised of nitinol metal have been demonstrated to have a unique advantage in achieving compression through the alloy's unique inherent properties of shape memory and super elasticity. Nitinol implants offer the surgeon a tool to apply dynamic compression in fracture fixation and joint arthrodesis that adapts and persists after the patient leaves the operating room. Here we discuss the indications and use of a novel nitinol screw in foot and ankle surgery. Level of Evidence: Diagnostic Level IV. See Instructions for Authors for a complete description of levels of evidence.
