“…A study by Murakami et al showed that the level of constraint created by device affects the ground reaction force pattern (21). Additionally, Torres et al showed that the application of a stifle orthosis affected the kinematics for all joints and planes of motion at a walk and trot (22). This may specifically explain the noteworthy discrepancy between the improvement in TO with the device donned and without, as the tarsal devices induced a variable level of constraint based on the injury.…”

IntroductionThe use of orthoses and prostheses is expanding in veterinary medicine. However, research evaluating the efficacy and complications of these devices in veterinary patients is limited. The primary objective of this study was to prospectively determine the complications and outcomes associated with custom orthosis and prosthesis use in the canine patient.Materials and MethodsThis was a prospective, clinical trial that followed patients for 12 months following device fitting. Owner-perceived complications, clinical metrology instruments, and objective gait analysis were used as outcome measures at various time points. The patients were grouped into the following four major categories: Patients with a carpal orthosis, patients with a stifle orthosis, patients with a tarsal orthosis, and patients with a prosthetic device.ResultsForty-three patients were included in the study. Thirty-nine out of 43 patients (91%) experienced at least one complication, with 7/7 (100%) prosthesis patients experiencing at least one complication. At least one skin complication was reported for the following patient groups during the first 3 months of use: 8/14 (58%) stifle orthoses, 9/10 (90%) carpal orthoses, 6/10 (60%) tarsal orthoses, and 4/7 (58%) prostheses. Patient non-acceptance of the device was identified in 2/15 (14%) stifle orthoses, 1/10 (10%) tarsal orthoses, and 4/7 (55%) prostheses. One out of 15 (7%) stifle orthoses, 4/10 (40%) carpal orthoses, 4/10 (40%) tarsal orthoses, and 1/7 (15%) prostheses experienced mechanical device problems necessitating repair. The majority of patients with carpal and stifle orthoses showed improvement on objective gait analysis in percent body weight distribution of the affected limb between baseline and the most recent follow-up without the device donned: 83% (n = 6) of patients with carpal orthoses, 100% (n = 11) of patients with stifle orthoses. None of the patients with tarsal orthoses showed a similar improvement (0%; n = 4).Discussion and conclusionThree major complications associated with canine orthosis and prosthesis use were identified in this study as follows: Skin complications (abrasions, loss of hair, and sores), mechanical device problems, and patient non-acceptance of the device. Owners should be notified of these potential complications prior to pursuing orthoses or prostheses as a potential treatment option. Although clinical improvement was noted in the majority of patients with stifle and carpal pathology, given the lack of a control group, it is unknown how much of this improvement can be attributed to the orthoses.

“…Kinematic changes associated with joint disorders and treatments are commonly quantified with marker-based motion capture systems (Böddeker et al, 2012;Torres et al, 2017). For instance, with marker-based gait analysis, Böddeker et al (2012) found that, compared to the preoperative values, the stifle extension angle of cranial cruciate ligament-deficient dogs increased approximately 5 postoperatively throughout the gait cycle.…”

Background Soft tissue artifacts (STAs) are a source of error in marker-based gait analysis in dogs. While some studies have revealed the existence of STAs in the canine hindlimb, STAs and their influence on kinematic gait analysis remain unclear. Methods Thirteen healthy Taiwan dogs affixed with twenty skin markers on the thigh and crus were recruited. Soft tissue artifacts and their influence on the determination of segment poses and stifle angles were assessed by simultaneously measuring marker trajectories and kinematics of the underlying bones via a model-based fluoroscopic analysis method. Results Markers on the thigh showed higher STAs than those on the crus, with root-mean-square amplitudes up to 15.5 mm. None of the tested marker clusters were able to accurately reproduce the skeletal poses, in which the maximum root-mean-square deviations ranged from 3.4° to 8.1°. The use of markers resulted in overestimated stifle flexion during 40–60% of the gait cycle and underestimated stifle flexion during 80–90% of the gait cycle. Conclusions Considerable magnitudes and effects of STAs on the marker-based 3D gait analysis of dogs were demonstrated. The results indicate that the development of error-compensation techniques based on knowledge regarding STAs is warranted for more accurate gait analysis.

“…Bajo la luz de lo anterior, a nivel mundial, muchas Instituciones de Educación Superior y centros de investigación han desarrollado prototipos de interés, siguiendo metodologías del proceso de diseño, análogas entre sí, y que parten de la investigación de referentes que sirven para generar diversas alternativas de mecanismos, materiales y estética. En este sentido, países como España, Estados Unidos, Israel, Rusia y Suecia han direccionado esfuerzos para desarrollar dispositivos de inmovilización para animales, específicamente perros, como se muestra en varios trabajos, como por mencionar algunos, los de Antonana et al (2019); Popov et al (2019); Torres et al (2017); Wagoner et al (2018); Mesa (2020) y Pascual , todos direccionados a resolver el problema de movilidad y marcha del animal, utilizando como herramienta principal la manufactura aditiva (impresión 3D). A pesar de ello, muchos son equipos complejos con sensores electrónicos y con conectividad móvil, otros poseen componentes de electroestimulación para acelerar la recuperación del usuario y en otros casos, utilizan materiales especiales como la fibra de carbono.…”

En el mercado nacional no existen empresas ni proyectos académicos que trabajen en el desarrollo de órtesis de inmovilización para perros, solo se encuentran productos comerciales de importación con altos costos de adquisición y mantenimiento. En esta investigación se presenta una revisión sistemática de literatura que considera las órtesis caninas de inmovilización, haciendo singular enfoque en la impresión 3D. Se aplica el método de Torres-Carrión, planteando dos preguntas de investigación: a) ¿Qué tipo de tecnología utilizan las órtesis impresas en 3D de inmovilización para perros?, y b) ¿Cuáles son los métodos considerados en los estudios? La búsqueda en las bases de datos como Scopus y Google Scholar generaron diez y un artículo, respectivamente. Como resultados se destaca la utilización del escáner 3D para realizar digitalmente el levantamiento tridimensional del miembro afectado del animal y así procesar mediante paquetes computacionales el diseño, análisis del dispositivo para luego fabricarlo mediante la tecnología de impresión 3D. Concluyendo que no existen muchos estudios específicos sobre órtesis caninas impresas tridimensionalmente, abriendo una brecha para futuros estudios en este campo específico.
