correction of metatarsus primus varus associated with hallux valgus deformity using the Arthrex mini tightrope a report of 44 cases
Foot and Ankle Specialist, 2011Co-Authors: Stephen Kayiaros, Brad D Blankenhorn, Jordan Dehaven, Hans Van Lancker, Peter Sardella, James T Pascalides, Christopher W DigiovanniAbstract:Metatarsus primus varus must be addressed during correction of moderate to severe hallux valgus deformity. As an alternative to proximal osteotomy or first tarsometatarsal fusion for hallux valgus correction, this study presents a series of patients treated using the Arthrex Mini TightRope. A total of 36 patients (44 operations) with hallux valgus and metatarsus primus varus underwent correction using the Arthrex Mini TightRope. Assessment included measurement of radiographic parameters, the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot outcomes score, and the SF-12. The average hallux valgus angle improved from 32.2° to 15.2° (P < .0001). The average first intermetatarsal angle improved from 14.6° to 8.2° (P < .0001). The average distal metatarsal articular angle improved from 17.0° to 9.6° (P < .0001). The average AOFAS midfoot outcomes scores improved from 45.44 to 84.72 (P < .0001). Postoperative SF-12 physical and mental scores averaged 52.99 and 56.63. Only one patient had recurrence of deformity. Correcting metatarsus primus varus in association with hallux valgus deformity using the Arthrex Mini TightRope should be considered a treatment option. This technique is less invasive and seems capable of maintaining correction while allowing for early weight bearing and avoiding the need for a proximal first metatarsal osteotomy or Lapidus procedure.

clinical and radiologic outcomes following total shoulder arthroplasty using Arthrex eclipse stemless humeral component with minimum 2 years follow up
Journal of Shoulder and Elbow Surgery, 2018Co-Authors: Sian Gallacher, Huw Williams, Andrew King, Jeff Kitson, Christopher D Smith, William ThomasAbstract:Background Stemless humeral components benefit from less morbidity, better reproduction of the humeral anatomy, ease of revision, and fewer stem-related complications. Encouraging results are available up to 9 years after surgery from the designer's series. This is an independent study of 100 consecutive Eclipse stemless prostheses for osteoarthritis with a minimum 2-year follow-up (range, 2-6 years). Methods We included only total shoulder arthroplasties performed for osteoarthritis. The primary outcome was the Oxford Shoulder Score (OSS) after 2 years. Secondary outcome measures were change in shoulder range of movement and radiographic analysis of prosthesis size and position. Results The mean OSS at 2 years was 38 of 48, with a mean improvement of +19 points (range, +17 to +22 points; P Conclusion The functional and radiographic outcomes of Eclipse total shoulder replacement are excellent. We were able to accurately reproduce the native anatomy in the majority of cases, with no implant loosening, at 2 to 6 years' follow-up.

Pectoralis major tendon repair: a biomechanical study of suture button versus transosseous suture techniques
Knee Surgery Sports Traumatology Arthroscopy, 2015Co-Authors: William Thomas, Sabina Gheduzzi, Iain PackhamAbstract:Purpose Pectoralis major tendon avulsion injury benefits from surgical repair. The technique used and speed of rehabilitation in this demanding population remains subject to debate. We performed a biomechanical study comparing suture button (Pec Button™, Arthrex, Naples, FL) with a transosseous suture technique (FibreWire, Arthrex, Naples, FL). Methods Freshly slaughtered porcine humeri were prepared to model a single transosseous suture or suture button repair. A static, tensile load to failure experiment and a cyclic, tensile load experiment to model standard (10,000 cycles) and accelerated rehabilitation (20,000 cycles) philosophies were tested. The mode of failure, yield and ultimate failure load, extension (clinical failure >10 mm) and the resistance to cyclic loading was measured. Results The mode of failure was suture fracture in all the static load experiments with 10/11 occurring as the suture passed through the button and 7/11 as the suture passed through the bone tunnels. There was a significant difference in yield load, favouring transosseous suture [ p = 0.009, suture button (SB) 673.0 N (647.2–691.7 N), transosseous suture (TOS) 855.0 N (750.0–891.4 N)] and median extension, favouring suture button [ p = 0.009, SB 8.8 mm (5.0–12.4 mm), TOS 15.2 mm (13.2–17.1 mm)]. 2/3 transosseous suture and 0/3 suture buttons failed before completing 20,000 cycles. The difference in mean number of cycles completed was non-significant. The difference in mean extension was 5.1 mm (SB 6.7 mm, TOS 11.7 mm). Conclusions Both techniques show advantages. The difference in extension is likely to be more clinically relevant than load tolerated at failure, which is well above physiological levels. The findings do not support an accelerated rehabilitation model.

bioabsorbable fixation screw for proximal interphalangeal arthrodesis of lesser toe deformities
Foot & Ankle International, 2017Co-Authors: Jascha Armin Wendelstein, Reinhard Schuh, Peter Goger, Peter Bock, Hansjorg TrnkaAbstract:BACKGROUND: Although standard fixation of proximal interphalangeal (PIP) arthrodesis by K-wire is relatively inexpensive and well established, it does have some drawbacks, making newer fixation devices interesting. The aim of this study was to clinically and radiologically assess the operative correction of the lesser toe deformation in the form of a PIP arthrodesis using a bioabsorbable 2.7-mm fixation screw. METHODS: From January 2011 until October 2013, 34 patients underwent a PIP arthrodesis using the TRIM-IT (Arthrex) 2.7-mm fixation screw and were contacted for this retrospective cohort study. At an average of 3.3 years after the operation, 24 patients and 26 toes were evaluated clinically, radiologically, through pedobarography, and a patient-satisfaction survey. RESULTS: Using the PLLA screw for fixation, 84.6% showed bony union of the arthrodesis, and 84.6% were satisfied. Mean AOFAS score was 82.7 points and thus regarded as good. The mean VAS score was 1.3/10. Overall, 73.1% of the toes showed good alignment, and 7.7% had a painless recurrence of deformity and were still satisfied with the intervention. In addition, 34.6% had floating toes, but only 4.2% without Weil osteotomy or encroachment. Further, 3.8% were advised to undergo a revision because of severe misalignment. CONCLUSION: The 2.7-mm bioabsorbable fixation screw yielded results that were comparable to other fixation devices for PIP fusion fixation regarding success rate, revisions, and patient acceptance. LEVEL OF EVIDENCE: Level IV, retrospective case series.

comparison of brostrom technique suture anchor repair and tape augmentation for reconstruction of the anterior talofibular ligament
Knee Surgery Sports Traumatology Arthroscopy, 2016Co-Authors: Reinhard Schuh, Emir Benca, Madeleine Willegger, Lena Hirtler, Shahin Zandieh, Johannes Holinka, Reinhard WindhagerAbstract:Purpose Recently, tape augmentation for Brostrom repair has been introduced in order to improve the primary stability of the reconstructed anterior talofibular ligament (ATFL). The biomechanical effect of tape augmentation suture anchor (SA) repair is not known yet. The aim of the present study was to compare construct stability of the traditional Brostrom (TB) repair compared with a stand alone SA repair (SutureTak®, Arthrex) and SA repair combined with tape augmentation (InternalBrace®, Arthrex) internal brace (IB) of the ATFL.

biomechanical stability of tape augmentation for anterior talofibular ligament atfl repair compared to the native atfl
Knee Surgery Sports Traumatology Arthroscopy, 2016Co-Authors: Madeleine Willegger, Emir Benca, Lena Hirtler, Johannes Holinka, Reinhard Windhager, K Hradecky, Reinhard SchuhAbstract:Purpose Current methods of anterior talofibular ligament (ATFL) reconstruction fail to restore the stability of the native ATFL. Therefore, augmented anatomic ATFL reconstruction gained popularity in patients with attenuated tissue and additional stress on the lateral ankle ligament complex. The aim of the present study was to evaluate the biomechanical stability of the InternalBrace® (Arthrex Inc., Naples, FL, USA), a tape augmentation designed to augment the traditional Brostrom procedure.
