Abstract

FIELD: medicine.

SUBSTANCE: invention relates to veterinary, in particular, to method of introducing medications into knee joint cavity in dogs. Method of introducing medications into knee joint cavity in dogs includes performing injection, with medication being introduced into cavity of bursitus praepatellaris, after which flexion-extension motions in knee joint with rhythm 5-10 movements per minute are performed for 1-2 minutes.

Description

The invention relates to the field of veterinary medicine and can be used in the treatment and diagnosis of pathology of the knee joint in dogs.

There is a method of introducing drugs for therapeutic and diagnostic purposes into the cavity of the knee joint by puncture with an injection needle, which is inserted at right angles to the medial edge of the ligament of the patella in the region located in the middle of the distance between the distal edge of the patella and tibial roughness (Shebitz X., Brass V. Operative Surgery of Dogs and Cats. M: Aquarium print, 2005. S. 62).

However, with this method, damage to the articular cartilage, subchondral bone and ligamentous apparatus of the knee joint is not excluded.

A known method of introducing drugs into the knee joint using an arthroscope (RF Patent No. 2359631, publ. June 27, 2009).

However, this method also does not exclude damage to the joint formations.

The objective of the invention is to reduce the morbidity of the performed manipulations and the prevention of iatrogenic complications.

This problem is solved by the fact that in the method of introducing pharmacological preparations into the cavity of the knee joint in dogs by injection, the drug is injected into the cavity of the prepatellar bursa, after which the flexion-extensor movements in the knee joint with a rhythm of 5-10 movements in a minute.

The method is illustrated by a description, an example of practical use and illustrative material, which shows:

figure 1 - x-ray of the knee in lateral projection after the introduction of radiopaque substances into the cavity of the prepatellar bursa;

figure 2 - x-ray of the knee in lateral projection after complete diffusion of the radiopaque substance from the cavity of the prepatellar bursa into the cavity of the knee joint.

The method is as follows.

The dog is laid on its side so that the affected joint is on top. The pelvic limb is unbent, grasping the kneecap with the thumb and forefinger, palpating the place of fixation of the quadriceps femoris tendon to the patella, and shifting the tendon by 2–3 mm in the medial direction. From the lateral surface in the caudaventral direction at an angle of 45 ° to the transverse plane, an injection needle punctures the cavity of the prepatellar bursa and introduces the drug in the required volume.

After that, within 1-2 minutes, flexion-extensor movements in the knee joint are performed with a rhythm of 15-20 movements per minute, which leads to the diffusion of the drug from the cavity of the prepatellar bursa into the cavity of the knee joint.

The practical use of the method is illustrated by the following observation.

Dog, Central Asian Shepherd Dog, male, 7 months old. To diagnose the condition of the left knee joint, a radiopaque substance was introduced into its cavity.

For this, the animal was fixed on the right side. The left pelvic limb was straightened, by palpation, the place of fixation of the tendon of the quadriceps femoris to the patella was determined and it was displaced by 2-3 mm in the medial direction. From the lateral surface in the caudaventral direction at an angle of 45 ° to the transverse plane, an injection needle punctured the cavity of the prepatellar bursa into which 1 Omnipack was introduced (Fig. 1). After that, passive flexion-extensor movements in the dog’s knee joint with a rhythm of 10 movements per minute were performed for 1 minute. On the performed x-ray diffusion of the radiopaque substance was noted from the cavity of the prepatellar bursa into the cavity of the knee joint (figure 2), which made it possible to diagnose its condition.

Practical use of the method showed that its use reduces the morbidity of the performed manipulations with the introduction of drugs into the cavity of the knee joint and prevents iatrogenic complications.
