Diagnostics

In what cases do they perform and what does ultrasound of joints show?

uzi knee joint An examination of anatomical structures using ultrasound has long been used in medical practice around the world.

This examination is based on the reflecting properties of sound, namely ultrasound.

To date, to observe the full clinical picture of any disease is almost impossible without ultrasound.

This method is completely painless, highly informative and not invasive.

The study is carried out using a special device that emits ultrasonic waves of a certain frequency that are not perceived by human hearing organs.

With the help of reflective properties of high-frequency sound waves, a specialist can obtain an image of the organ or tissue being examined on a computer monitor.

When the boundaries of media of different densities pass, the ultrasonic signal is divided: some of it continues to spread to the tissues of the new medium, and the other part is reflected from it.

The speed of reflection and propagation depends on the frequency of the signal applied to the organs of the signal. Reflection will be more intense if the difference in tissue density is greater.

The essence of the

method Ultrasound examination of the joints is a modern diagnostic method. joint diagnostics

The special scanner of the ultrasound machine fixes the interaction of ultrasonic waves with the tissues of the joints and sends a signal to the monitor.

Immediately on the monitor a complete clinical picture is displayed. The joint consists of cartilage, ligaments, tendons and fluids, all of which have different densities. Look at the screen they will be as different structure, and displayed in different colors.

In order for ultrasonic waves to propagate well around the joint tissues, it is necessary to exclude the possibility of forming an air gap between the tissue and the scanner being examined. Special gels are used for this.

Advantages of ultrasound investigation

One of the most common and many advantages over such methods of examination as radiography and arthroscopy is the ultrasound examination of the joints.

Its advantages include:

  • research speed;
  • painless;
  • security;
  • cost;
  • no contraindications;
  • no need for special preparation for examination;
  • obtaining the result at the time of the study;
  • accuracy of the definition of joint pathology;
  • possibility of multiple examination without harm to the body;
  • thanks to the method, it is possible to detect joint defects in real time.

For arthroscopic manipulation and tissue taking on a puncture, the ultrasound machine is an indispensable assistant. The surgeon during the operation sees his actions, which helps him to conduct the procedure safely.

What joint problems reveal ultrasound

Using ultrasound diagnostics, doctors can detect changes not only in bone structures, but also in soft tissues of the entire musculoskeletal system: ligaments, tendons, muscles and synovial bags.

One of the main methods for injuries

Trauma of tendons and ligaments is possible with excessive load on them or with awkward movements.

Ultrasound with trauma Using an ultrasound examination of the joints, it is possible to detect injuries to its tendons or ligaments. For example, an ultrasound of the knee joint shows a rupture of the patellar ligament, trauma to the outer or lateral ligaments.

The US of the hip joint shows tears or lesions of the quadriceps femoris.

On the monitor, ligament ruptures appear as hypoechoic areas between damaged tissues. Often, in damaged areas, hematomas are found.

Pathologies in the joints

Any pathology of the meniscus, including their dystrophic changes and postoperative conditions, manifests itself in ultrasound imaging as a violation of the lines of their contours and formation of hypoechoic gaps.

Also on the pictures can be found edema, the displacement of tissues and ligaments. The heterogeneity of the structure is a sign of degenerative changes.

Degenerative processes

Such degenerative processes in bone tissues, like alcinification, are manifested during the examination in the form of detection of hyperechoic formations and multiple ossification.

With arthrosis, such degenerative changes as the narrowing of the gap between the joints, the unevenness of the surfaces of the joints are possible.

Detection of the

cyst. During examination of the joints, tumors and other tumors can be found. They are visualized in the form of cavities filled with liquid.

Inflammatory processes in the joints

The occurrence of an inflammatory process in the joint can be evidenced by the discovery in it during the study of free fluid.

With the help of ultrasound, inflammation of synovial membranes, rheumatic manifestations, hyperplasia and sarcoma can be detected.

Tendinitis manifests itself in the form of reduced echinality of the affected tendon.

What joints investigate

Using ultrasound can be examined:

  • knee joints and ankle;
  • hip joints;
  • shoulder joints, elbows, wrist bands.

Knee and ankle examination

The knee and ankle ultrasound is performed for the purpose of revealing the pathology of connective tissue, as well as for diagnosing after the Uzi knee trauma.

With the help of ultrasound, tissue diseases can be detected even before the inflammatory process begins.

This type of study is also used to determine the cause of pain in the knee area.

Indications for examination:

  • bruises;
  • trauma to menisci or ligaments;
  • suspicion of the occurrence of neoplasms( cysts, tumors);
  • suspected of the occurrence of an inflammatory process of an infectious or degenerative nature.
The study allows to assess the condition of not only soft tissues, but also their connecting elements, vessels and nerve endings.

Study of hip joints

During the examination, the joint structure is visualized, the cartilaginous tissue is examined, the presence and characteristics of the fluid are detected, neoplasms or defects are detected.

Ultrasonic diagnosis of the hip joint makes it possible to identify inflammatory processes, with the definition of its nature: rheumatic or other damage.

Indications:

  • tenderness;
  • impaired motor function;
  • deformation;
  • edema;

Suspected of the following pathologies:

  • arthrosis with tissue deformation;
  • inflammatory processes of the synovium;
  • necrosis.

With the help of this study, it is possible to diagnose tissues, muscles and ligaments, determine whether there are stretches of bruising or swelling.

Diagnosis of the shoulder and elbow joint

The ultrasound of the shoulder joint allows you to assess the condition of the muscles and ligaments of the shoulder joints, to detect the inflammatory processes that began in them or the degenerative changes in muscles, cartilage and tendons.

For what indications:

  • pain;
  • tendonosis( inflammation of the tendons);
  • suspected liquid formation;
  • tendon ruptures.

When diagnostics are assigned

Indications for diagnosis:

  • joint crunching while driving;
  • pain;
  • injury;
  • occurrence of edema;
  • suspected of having arthritis;
  • suspected of arthrosis;
  • dysplasia.
Contraindications: the presence of damage to the skin and open wounds.

Ultrasound of the hip joints in newborns

Ultrasound of the hip joints in newborns Newborn hip joint research is conducted with the aim of early detection and further correction of subluxations and pre-injuries during childbirth and dysplasia.

The examination should be performed prior to ossification of the tibia head, since the shadow formed as a result of its ossification interferes with visualization.

It is recommended that all babies be examined, a special need arises from the indications:

  • birth injuries;
  • incorrect presentation;
  • hereditary factor;
  • asymmetric creases on the legs;
  • asymmetric limbs.

Early diagnosis makes it possible to correct the situation with the help of conservative methods of treatment: massage, physiotherapy and orthopedic adaptations. In cases of late detection of pathology, one must resort to a surgical procedure.

Preparing for the

study No special training is required for this study. For babies it is recommended to conduct a test for a full stomach: feed an hour before the procedure. If the child has caught a cold, it is better to transfer the ultrasound.

Procedure of

The patient is placed on a couch, a special gel is applied to the site under study. In the study zone, the doctor conducts a special sensor and examines the image on the screen.

During the procedure, it may be necessary to study the joint from different points, you need to change the position.

The procedure takes from 15 to 20 minutes.

Answers to patients' questions

ultrasound joints in questions and answers.

Why does one joint hurts, and another is examined?

Sometimes an ultrasound doctor can prescribe a study not at all those joints that bother the patient.

The fact is that the diagnosis of such a disease as rheumatism, it is possible with ultrasound not at all joints.

With regard to the knee joint, even minor changes or the onset of inflammation will immediately be seen in the ultrasound picture.

Why is a healthy joint examined at the same time as a patient?

For a complete examination, it is necessary to check not only one joint. For example, for a knee or elbow joint, a paired study must be carried out.

Thus, it is possible to compare the condition of the ligaments, cartilage and tendons of the patient joint relatively healthy.

Why is it necessary to undergo several examinations?

For a more thorough study, some diseases should be observed in dynamics. This concerns the periods of exacerbations and remission of diseases. And for such a disease as osteoporosis, constant monitoring is necessary.

Is it safe to use ultrasound?

Ultrasonic waves do not exert an irradiating effect on the body, but, conversely, at certain frequencies produce a therapeutic effect.

Ultrasound is also used as a physiotherapeutic procedure, which has spasmolytic, analgesic, analgesic and resolving action.

Where it is possible to pass the examination

Ultrasound joints can be done in clinics in every city. ultrasound in the hospital

In Moscow, the cost of the study is:

  • clinic Miracle Doctor - 1,700 rubles;
  • CM clinic - 1800 rubles;
  • NIARmedik - 1900 rubles;
  • The Royal Clinic - 900 rubles.

In other cities of Russia such pricing:

  • in St. Petersburg price of ultrasound joints from 1500 to 1700 rubles;
  • in Kazan - from 550 to 1200 rubles;
  • in Yekaterinburg - 750 - 1100 rubles;
  • in Perm - 700 rubles;
  • in Ufa - 800 rubles. The

ultrasound is one of the leading methods of joint diagnostics that does not require special preparation, has no contraindications, allows to identify the disease at early stages, and is economically profitable.
