Design of a loading system for cyclic test on sutured organs

The design of loading systems to test biologic samples is often challenging, due to shape variability and non-conventional loading set-ups. In addition to this, large economic investments would not be justified since the loading set up is usually designed for one single or for a limited range of applications. The object of this work is the development of a loading set-up finalised to on-site testing of sutures whose main function is applying a localised tensile load. The main challenges of this design process can be so summarized: Applying cyclic tensile loads on the suture wire, mimicking the physiologic condition where both suture anchorage points have a certain compliance; Designing a loading system as versatile as possible, in order to be able to accommodate organs with different geometries and sizes; Keeping low both the complexity and costs of realization. All these considerations and the design calculi are here reported in detail, discussing the novelty of the system, and its main advantages.

“…Thirty-nine horses, euthanized for reasons unrelated to the study, were used for the second part of the study. 12,13,[21][22][23][24][25][26][27] Owners gave permission for their animals to be used in research studies after euthanasia. Just after euthanasia, headneck segments were removed at the level of the fourth to sixth cervical vertebra and deep frozen at −20 C. They were thawed at room temperature 48-72 hours before the implantation procedure.…”

“…The prosthesis replaces the dysfunctional cricoarytenoideus dorsalis muscle and attaches the arytenoid to the cricoid cartilage resulting in a permanent abduction of the arytenoid cartilage. The prosthesis may consist of non-absorbable sutures alone or in combination with metallic anchoring materials, based on the surgeons preference (Brandenberger et al, 2017;Lechartier et al, 2015;Schumacher et al, 2000). Once the prosthesis is in place, it is tightened under endoscopic control, in a way that an ideal abduction of the arytenoid is achieved.…”

“…This complication is more often seen in grade III horses, due to the continuous movement made by the not fully paralyzed arytenoid. Up to 20% of these cases present loss of abduction (Brandenberger et al, 2017;Dixon et al, 2003a;Lechartier et al, 2015). To try and avoid this, some surgeons curette or inject the cricoarytenoid joint with polymethylmethacrylate to induce ankyloses, which may result in a better stabilization of the arytenoid position (Barnett et al, 2013a;Leutton and Lumsden, 2015;Parente et al, 2011).…”

Laryngeal hemiplegia is a progressive upper airway dysfunction in the horse. It is not only seen in thoroughbred racehorses but also in warmblood horses, draft horses and in ponies. The condition is most frequently seen on the left side. The left laryngeal recurrent nerve gradually loses function and the function of the left cricoarythenoideus dorsalis muscle is compromised. This condition is most often idiopathic. It possibly leads to exercise intolerance but a respiratory noise is often the primary complaint of the owner. Right sided laryngeal hemiplegia is almost always related to other pathologies causing the nerve to malfunction. The diagnosis is not always easy because of the restricted availability of endoscopy in the field. A better understanding of laryngeal ultrasound examination might offer a new possibility in diagnosing laryngeal hemiplegia. If abnormal inspiratory sound is the only problem, laser treatment alone can be satisfactory. If the horse shows clear signs of exercise intolerance, further treatment is needed. If correctly executed, the outcome of laryngoplasty is good. Other techniques, like nerve grafting and pacemakers, are being explored and might even be regarded as better alternative treatments in the future, as these are more physiologic compared to laryngoplasty. In sporthorses presented with idiopathic laryngeal neuropathy without postoperative complications, the prognosis is good.

Ex vivo biomechanical stability of 5 cricoid‐suture constructs for equine laryngoplasty

Abstract: Loss of abduction after equine laryngoplasty may be reduced and pullout forces increased by applying a MB construct in the cricoid cartilage. In vivo testing is required to verify these results.
