“…Nos primeiros 21 dias após sutura, recomenda-se associar imobilização externa, pois sua estrutura com fibras orientadas em sentido longitudinal não sustenta adequadamente os pontos de síntese (Raiser, 2001 A constante preocupação em tentar minimizar os danos decorrentes das injúrias tendíneas tem levado ao desenvolvimento de inúmeras pesquisas com o intuito de encontrar um material adequado à cicatrização tendínea, com resistência suficiente, sem alterar seu comprimento e a fim de manter a capacidade de deslizamento, principalmente em situações em que há perda de substância, com consequente não união das extremidades tendíneas. A ruptura do tendão calcâneo, que figura como uma das mais frequentes injúrias tendíneas observadas no cão, geralmente apresenta esse tipo de problema (Costa Neto, 1999).…”

RESUMOCom este trabalho objetivou-se avaliar o processo de cicatrização do tendão em coelhos, utilizando-se no grupo tratamento o filme de quitosana, por meio de uma análise clínico-cirúrgica e histológica. Foram utilizados 12 coelhos adultos, separados em grupo controle (GC) e grupo tratamento (GT), nos quais se realizou uma secção parcial do tendão gastrocnêmio de ambos os membros pélvicos. A avaliação clínica baseou-se na presença de reação inflamatória, infecção, dor e deiscência da sutura. Para a avaliação histológica, foi realizado um estudo comparativo do processo cicatricial por meio do tipo de células, da quantidade de tecido conjuntivo e da organização das fibras colágenas entre os grupos e os momentos. Nas feridas cirúrgicas, não foram observadas secreção, dor ou deiscência. Na histologia comparativa entre os grupos, o GC apresentou melhor processo cicatricial em relação ao GT, aos 60 dias. Aos 90 dias, no GT a cicatrização já esboça recuperação do tendão, com reorganização da celularidade e das fibras colágenas no tecido conjuntivo denso modelado. Concluiu-se que a quitosana estimula rápido crescimento celular, mas de forma desorganizada, e que a cicatrização completa só ocorre após 90 dias da sua implantação no tecido. A quitosana é um polímero natural derivado do processo de desacetilação da quitina, que é assumido como o segundo polissacarídeo mais abundante da natureza, atrás apenas da celulose http://dx

“…In this report, besides the modified Kessler standard suture technique, a stainless steel neutral orthopedical plaque was included and fixed by separated single sutures encompassing the tendinous tunic and about a half of the tendon in thickness and proportioned temporary local joint movements restrictions throughout external skeletal fixation, with central threaded pins and polymethylmethacrylate. Other techniques for the tendinous suture tension reduction and for the tibiotarsal joint temporary immobilization, were already successfully used on repairing the common calcaneal tendon (COSTA NETO et al, 1999;RAISER, 2001). The glycerin preserved bovine peritoneum sutured to the common calcaneal tendon was successfully used for repairing common calcaneal tendinous injuries of dogs with minimal inflammatory reaction, being incorporated to the scar tissue and serving as a foundation for a new tissue development, thus restoring the tendon structure (COSTA NETO et al, 1999).…”

The common calcaneal tendon is one of the most injured tendons in dogs. Regardless the cause, if untreated, the injury may increase permanently compromising the injured limb function. This is a case reported in a seven years old, male, 31.5 Kg, very hecticbehavior, Labrador dog. The dog had been suffered a cut by walking on a wasteland. At the clinical examination, he presented claudication, knee hyperextension and tarsal hyperflexion. At the common calcaneal tendon palpation, a loss of continuity was realized characterizing a rupture. The injury was surgically treated by approximating the tendon ́s stumps. Aiming to reduce the tension over the tendon, a plaque was sutured in the tendon caudal surface and the tarsocrural joint was temporarily immobilized. The calcaneal tenorrhaphy with modified Kessler suture associated to an orthopedical plaque and external skeletal fixative showed to be efficient to promote a dog ́s common calcaneal tendon early repairing. The healing occurred by first intention and the injured limb had a deambulatory restoration even in the first postoperative week. Such conducts have also to be considered in calcaneal tenorrhaphies in active, heavy and/or uncooperative patients.

“…A sutura utilizada para a tenorrafia patelar, bem como o tipo de fio, seguiu as recomendações de Raiser [15]. Do mesmo modo que em outro estudo [11], optou -se por uma sutura de reforço, tipo Wolff, garantindo uma adequada aposição das fibras e evitando a tensão exercida pelo músculo quadríceps.…”

Background: In cases of patellar tendon ruptures, there is a need for primary repair by sutures aiming to restore the extensor mechanism of the knee and prevent degenerative sequelae. Even though the need for temporary immobilization of the joint reconstruction surgeries involving tendons and ligaments, seeks to avoid or minimize the undesirable effects of disuse without any interference at the surgical site. Thus, the objective of this research was to propose a model of joint immobilization adjustable in dogs undergoing patellar tenorrhaphy to allow, in the immediate postoperative period, the achievement of physical therapy modalities without interfering with the healing of the involved structures.Materials, Methods & Results: The dogs were randomly divided into two groups called fixed immobilization or GF (6 dogs) and adjustable or GA (5 dogs) immobilization. Once on plane and restrained in dorsal decubitus, lateral incision was performed on the right knee in dogs GF and GA for total section of the patellar tendon at its insertion 10 mm at the tibial crest. Immediately, it was made with tenorrhaphy modified Kessler suture pattern using monofilament nylon wire nº 1, followed by a Wolff point involving modified Kessler suture with the same type of wire. In both groups, the joint was immobilized femorotibiopatelar percutaneous external fixation biplanar at an angle of 110° for 30 days. The groups differed by the material used to connect the percutaneous pins, being employed in the GF acrylic resin, and in GA dogs was made adjustable apparatus which consisted of two stainless steel plates with rounded ends with three equally spaced holes 2.5 mm between them in the central part of the plate and the edge of 6mm, which is joined with the other plate by a nut and bolt and allowing to adjust the desired angle of the device. Were utilized four Steinmann pins 2.5 mm, two in the femur and two tibia, introduced perpendicularly to the bone. The assembled apparatus was encased in percutaneous pins and stuck with stainless steel nuts and lock washers causing immobilization of the knee joint, however adjustable in the period of application of physiotherapy protocol. The results demonstrated a reduction in measures in the period of 30 days, indicating that there was muscle atrophy. At 60 days post-operative values demonstrating increased muscle mass gain probably the bearing of the affected limb to the ground. In this study, was possible to observe that the values at 60 days did not return to the same found preoperatively, and the dogs GF and GA were on average 92.19% of the initial values. As for gait analysis, all dogs GF and GA were grade 5, 1 and 3 of lameness in the preoperative period and after 30 and 60 days after surgery, respectively.Discussion: The joint immobilization in dogs submitted to tenorrhaphy is required, however, the member cannot be used properly, which can lead to sequelae such as muscle atrophy from disuse and especially joint blockage. Currently in human medicine assisted rehabilitation in the immediate post-operative recovery involving the reconstruction of tendons and ligaments, without the need for joint immobilization is required, because patients are instructed to restrict the movements postoperatively. In veterinary medicine, however, it becomes risky this type of conduct, especially the lack of control the movements made by animals, arousing interest in this research to propose joint that could be undone each day to allow implementation of a method of immobilization physiotherapy and at the end of the session, the joint was immobilized again. According to the results, we can conclude that the temporary immobilization with adjustable articulating fixator in dogs submitted to patellar tenorrhaphy allows the use of a physical therapy protocol during the period of immobilization, without interfering with the healing of tendon anastomosis.
