In 35 body weight Great Dane a teflon texture was used as a prosthesis of the origo of the long digital extensor tendon. By the lateral parapatellar incision the stifle joint was opened. Translocated to the intermeniscal ligament avulsed tendon was uncovered and 2.5 mm in diameter hole in the osseous end of the tendon was bored. Through this hole a teflon texture was passed and the margines were sutured to itself, close holding the osseous end of the tendon. The teflon was threaded through the tunnel drilled from the point of the natural origo to the central area of the lateral condyle. The teflon band was knoted under the tension and the button was seated at the exit of the tunnel on the lateral surface of the condyle. The joint and soft tissues were sutured by interrupted sutures (dexon 3/0) and skin by continuous Halsted suture of 3/0 polyamid. Debecilline at a dose of 1.2 million iu was administered intramuscularly. Healing was rapid and in the course of one year any lameness and other disturbances were not observed.
The surgical correction of the iatrogenic quadriceps muscle contracture and the corrective insertiotomy of the semitendinosus muscle performed as a second stage surgery was described as two separate cases. In the first case (boxer, eight month old) using a long parapatellar approache the vestus lateralis muscle was uncovered and dissected longitudinally to the point 10 cm above the patella. Adherent to the femur vestus intermedius muscle eas divided as far to the hip as possible. The U-shaped flap of the muscle rectus femoris at its insertion was created to make the muscle longer. Additionally, the bilateral capsulotomy and desmotomy of the femoro-patellar ligaments associated with the dissection of the proximal femoro-patellar pouch were made. The Robert-Jones bandage in 90° of flexion stifle was applied for 7 days. The normal gait recurred after one month from the operation. In second case (fox-terrier, 6 months old) at one month after surgical correction of the IV° patellar luxation, the last sign of disease, which was the contracture of the semitendinosus muscle was definitivelly overcame through its insertiotomy. The long time follow-up was good in both cases.
В боковом предлежании собаки кожу и фасцию прорезывают, начиная от 1/2 лопатки до 1/2 плеча, минуя спереди плечевой сустав. Плечевую мышцу разделяют вдоль волокон, а находящиюся глубже подостную мыцу отклоняют вниз и назад. Пролегающий над сумкой надлопаточный нерв отодвигают, а суставную сумку прорезывают вдоль суставной щели. Закрывают сустав непрерывным швом из дексона 3/0 и перемизия дельтовидной мышцы узловыми швoми (дексон 3 0). Фaсuю и подкожную ткань приближают отдельными ярусами непрерывных швов (дексон 3/0), а кожу — внутрикожным швом Гольстеда (полиамид 0). После операции — движение на поводке 14 дней. Удаление кожного шва через 10 дней. Оперировали этой техникой 14 собак весом 25—60 кг и все перестали хромать на следующий день после операции. Отдаленные результаты (до 2,5 года) очень хороши.
A throughpatellar arthrotomy was performed in four horses, three experimental and one clinical case. The pur­pose of the studies was to asses the possibility of dividing the patella and the quality of healing process occurring. The patella was divided along the axis of the middle patellar ligament and later stabilised with an orthopaedic Wire (1 case) or cancellous screws (3 cases). Two horses (50',/o) had a local postoperative complication which necessited a humane destruction while two horses (50°/o) re- tourned to normal life. According to the author from a mechanical point of view the most advantageous approach would be to incise the stifle along the axis of the static and dynamic forces acting from the quadriceps muscle. This approach should enable the widest access to the femoro-patellar joint and sucessful healing. The effi­cacy was 100"Vo in all cases which were fixed with can­cellous screws. The reported approach is more advana- geous than cranio-lateral and lateral tecause provide adequate exposure of the whole articular surface of the trochlea and of the patella. The signs of the secondary degenerative joint disease were not found histologically in both operated with good result horses.
