“…Numerous studies have demonstrated the safety and efficacy of the use of nitinol compression staples in TMT fusion 3,9,13,14,16,23 and generally have fusion rates near 90%, comparable to literature rated for conventional fixation. 19 Although some clinical data exist regarding union rate using BME ELITE compression staples in TMT fusion, the data lack objective preoperative and postoperative data and analysis.…”

“…1,9,22 This feature of recovering a prior shape, enables the specific staple used in this series to be implanted after reduction and alignment of the fusion site with the expectation that the staple would begin to impart compression at the intended fusion site after it was released from its “inserter.” 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. 1 -3,5,9,14…”

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.

“…These have been used extensively in foot surgery as a reproducible way of achieving good arthrodesis with good results. [16][17][18] Spinal surgeons have also used heat sensitive titanium nickel alloy staples in an experimental treatment of scoliosis. 19 The use of these devices in the wrist has been described in a report that looked retrospectively at the outcomes of scaphoid waist fixation with memory staples.…”

Radioscapholunate Arthrodesis — A Prospective Study

et al. 2009

The purpose of this prospective study was to evaluate pain levels, range of motion, patient activity and satisfaction after radioscapholunate (RSL) arthrodesis. This was in association with distal scaphoid excision and complete resection of the triquetrum. The non-union rate for radioscapholunate arthrodesis was examined and the results compared with previous studies. Twenty-three patients (14 males and nine females) with an average age of 47 (range 26-73) years underwent RSL fusion for post-traumatic osteoarthritis, rheumatoid arthritis and Kienböck's disease of the lunate with a mean follow-up of 32 (range 13-70) months. The absolute prerequisite for any of these groups of patients was a functional midcarpal joint which was assessed pre-operatively with radiographs and intra-operatively prior to RSL fusion. The average flexion to extension motion changed from 66 degrees to 57 degrees . The ulnoradial range of motion also increased to 43 degrees from a pre-operative value of 22 degrees . The patients visual analogue pain scores reduced from an average of 64 to 28 (p = 0.01). Nineteen patients had no restriction in activity and all but one was satisfied with the outcome. All patients remained in full time employment with ten returning to some form of sport. RSL fusion with excision of the distal pole of the scaphoid and the entire triquetrum led to minimal reduction in the flexion-extension arc of motion and an increase in the ulnoradial arc. There was also good pain relief and maintenance of a patient's function. Memory staples are also an effective method of securing fusion in the wrist obtaining similar results to that seen in forefoot surgery.

“…The shape memory effect relates to the fact that the alloy reverts to its original shape after heating above a specific temperature; superelasticity is a phenomenon by which the stress value remains nearly constant up to a certain point of wire deformation. 1,2) These properties can be put to excellent use in various biomedical applications, [3][4][5][6][7] such as catheter guide wires, stents, orthodontic wires, and orthopedic implants for osteosynthesis.…”

<I>In Vitro</I> Biocompatibility of Ni-Free Ti-Based Shape Memory Alloys for Biomedical Applications

et al. 2010

This study was undertaken to evaluate the in vitro biocompatibility of newly developed Ni-free Ti-based shape memory alloys (SMAs) in comparison to that of commercial pure titanium (cpTi). This study compared Ti-24 mol%Nb-3 mol%Al (Ti-Nb-Al) and Ti-7 mol%Cr-3 mol%Sn (Ti-Cr-Sn) to cpTi from a cell-compatibility perspective. In all, 63 samples (21 samples for each group) were prepared, which were machined into 10-mm-diameter, 0.15-mm-thick, mirror-polished disks. Their surface morphology was evaluated using scanning electron microscopy (SEM). The chemical composition of the sample surface was determined using an energy dispersive X-ray analyzer (EDX). Sample surface roughness was measured using a non-contact 3D profiler. After sample surface observations, the cell proliferation and viability of African green monkey kidney fibroblast cell line COS7 in direct contact with these new alloys were evaluated by DNA quantification, by live cell imaging using CelLuminate Red fluorescent cell stain as a new method, and by cytoskeletal observations by immunofluorescent actin labelling. Cell proliferation was examined after 1, 3, and 5 days of culture. Results were the following. (i) Each sample showed high purity and a very smooth surface, showing no morphological differences among groups. (ii) The COS7 cells took in sufficient CelLuminate Red to visualize the cells using epifluorescent microscopy, and (iii) cell proliferation with Ti-Cr-Sn was lower than with either cpTi or Ti-Nb-Al. These results suggest that Ti-Nb-Al alloy showed biocompatibility as high as that of cpTi and that it is more suitable for biomedical applications.
