Method for the diagnosis of degenerative-dystrophic changes of the articular cartilage

 

(57) Abstract:

The invention relates to medicine, namely to traumatology and orthopedics, and can be used to diagnose areas of articular cartilage affected degenerative-dystrophic process. The method includes access to the articular cartilage via standard protocols for arthroscopy and visual inspection. Through arthroscopic cannula into the joint probe is introduced from the inlet of the laser beam with the fiber connected to a laser light source, and perceives the reflected beam with the fiber connected to a recording device. Irradiated articular cartilage laser beam with a wavelength of 0.63 and radiation power of 10 mW. According to the testimony of the device receiving the reflected laser beam, make a diagnosis of degenerative-dystrophic changes of articular cartilage: when the degree of dispersion of the laser beam g0,3 diagnose the norm, and if g<0,3 - degenerative-dystrophic process in articular cartilage. The method allows to objectively determine degenerative-dystrophic changes in the thickness of cartilage in the absence of external signs of defeat.

The invention relates to medicine, namely to traumatology and orthopedics, and can be COI CLASS="ptx2">Known methods of diagnostics of deforming arthrosis of large joints by clinical, laboratory and radiological signs.

A known method for the diagnosis of intra-articular injuries of the knee joint (1). The disadvantage of this method is the technical difficulty, the subjectivity of the results of the inspection.

There is a method of visual diagnostics of cartilage during arthroscopy, including access to the articular cartilage via standard protocols for arthroscopy and visual inspection (2).

The disadvantages of this method include its subjectivity, the inability to assess the state of deep structures of the cartilage, and that visual inspection is visible only significant destruction of cartilage, low diagnostic accuracy.

The purpose of the invention to provide opportunities to increase the accuracy and objectivity of the assessment of the deep structures of articular cartilage in the early stages.

This objective is achieved in that after arthroscopic cannula into the joint probe is introduced from the inlet of the laser beam with the fiber connected to a laser light source, and perceives the reflected beam with the fiber connected to the recording PR is, openimageio reflected laser beam, make a diagnosis of degenerative-dystrophic changes of articular cartilage: when the degree of dispersion of the laser beam g0,3 diagnose the norm, and if g<0,3 - degenerative-dystrophic process in articular cartilage.

The method is implemented as follows.

Preparation of the patient is conducted according to conventional methods. The patient perform arthroscopy, visually determine the condition of the articular cartilage. Through standard accesses alternately in the joint cavity enter arthroscopic cannula. Through the cannula into the joint injected with the probe placed in it two optical fibers. The probe down to the investigated area of the cartilage. The fiber that is connected to the source of laser radiation, miss beam intensity W=10 mW and wavelength =0.63 Ám. Passing and changing in the cartilage, the beam is reflected from the underlying bone. The reflected laser beam is perceived by the fiber connected with the registering device that registers the degree of scatter of the laser beam (g). For normal cartilage is characterized by the scattering g=0,35±0,05. In the cartilage of the affected degenerative-dystrophic process, there is a decrease in transparency, so that the dispersion becomes lower than that cool the s weak registers a reduction in the transparency of cartilage to laser beam g=0.3 to 0.25 in, dystrophic changes in the average degree of g=from 0.25 to 0.2. The lack of transparency below g=0.2 is typical for large-scale destruction of cartilage.

Thus, objectively determine degenerative-dystrophic changes in the thickness of cartilage in the absence of external signs of defeat.

Clinical example. Patient K., 37 years old, medical history, No. 2416, was admitted to hospital in Samara regional clinical hospital named after M. I. Kalinin with chronic rupture of the internal meniscus of the left knee. After the examination the patient underwent arthroscopy of the left knee revealed a patchwork gap internal meniscus, the last resected. The research condyles of the femur by the present method. Identified areas of reducing transparency of the cartilage, which indicates the beginning of the destructive and degenerative processes, despite the normal appearance of the cartilage surface by visual inspection. An appropriate treatment. The patient was discharged in satisfactory condition, and recommendations.

Thus, the proposed method allows us to objectively assess the Oia in practical health care.

SUBSTANCE: one should perform lovage in three stages:during the 1st stage one should carry out lovage of tracheoalveolar tree for 3-4 min with 60-80 ml 0.08%-sodium hypochlorite solution, at the 2nd stage one should introduce 5-7 ml 10%-fluimucyl solution into tracheobronchial tree for 4-6 min, and at the 3d stage one should perform lovage of tracheobronchial tree for 3-4 min with 60-80 ml 0.11%-sodium hypochlorite solution. The present innovation favors secreta release of decreased viscosity into large bronchi that simplifies its evacuation and this, in its turn, simplifies the access of antiphlogistic and antibacterial preparations towards tracheobronchial tree's mucosa that leads to interrupting inflammatory process in more shortened terms.

EFFECT: more prolonged period of remission.
