Why Ultrasound Navigation is Needed

Problem of Blind Injections

Even an experienced physician without visualization hits the target in 60-80% of cases for large joints (knee, shoulder) and 50-70% for small joints (ankle, wrist). This means up to 40% of the drug is injected in the wrong place.

Problem of Standard Ultrasound

With standard ultrasound guidance, the physician holds the probe in one hand and the syringe with needle in the other. It is difficult to stabilize both instruments simultaneously, especially for deep injections. Hand tremor leads to loss of needle visualization.

Solution: Sono Control Arm

The mechanical stabilizer fixes the ultrasound probe in the optimal position. The integrated needle guide ensures a stable trajectory. The physician sees the needle and target structure simultaneously on the screen in real time.

How Sono Control Arm Works

1. Scanning

High-frequency ultrasound probe (12-18 MHz) visualizes the joint, tendon, or ligament. The area of damage is identified: cartilage defect, tendon thickening, effusion, synovitis. Needle trajectory is planned.

2. Fixation

Sono Control Arm fixes the probe in the optimal position. The needle guide is set at the required angle. The probe remains stationary - visualization is stable.

3. Injection

The needle advances along the guide. The physician sees the needle tip relative to the target structure in real time. Upon reaching the target - injection of CGF and Lipogems®. Drug distribution is visualized on the screen.

4. Control

After injection - follow-up scanning. The drug appears as an echogenic zone in the correct location. Doppler confirms no vessel damage. Result documentation.

Advantages

No X-ray

Ultrasound only - zero radiation. Can be repeated unlimited times. Safe for patient and staff. Ideal for follow-up procedures.

Real Time

Real-time visualization of needle movement. Soft tissues visible: tendons, ligaments, nerves, vessels, synovial membrane. Dynamic assessment of drug distribution.

Stability

Mechanical fixation eliminates hand tremor. Needle follows the planned trajectory precisely. Especially important for deep injections and small target structures.

Soft Tissue Visualization

Ultrasound surpasses X-ray in visualizing tendons, ligaments, muscles, nerves, synovial membrane. Doppler shows blood flow and neovascularization.

Applications

Joints

Knee, shoulder, ankle, elbow, wrist. Intra-articular CGF + Lipogems® for osteoarthritis, synovitis, chondral defects. Accuracy of joint space targeting: over 98%.

Tendons

Rotator cuff, Achilles tendon, patellar ligament, elbow tendons (epicondylitis). Peritendinous or intratendinous injection. Ultrasound visualization of degeneration zone.

Ligaments

Collateral ligaments of the knee, cruciate ligaments (periarticular), ankle ligaments. Ultrasound visualizes partial tears and areas of inflammation.

Fascia

Plantar fascia (plantar fasciitis). Fascia thickening greater than 4 mm is visible on ultrasound. CGF injection precisely into the degeneration zone at the medial tuberosity of the calcaneus.

Sono Control Arm vs Cyber Navi Hand

Parameter	Sono Control Arm	Cyber Navi Hand
Visualization	Ultrasound (real-time)	X-ray + robotization
Radiation	None	Minimal
Soft tissues	Excellent	Limited
Bony structures	Superficial	Excellent (deep)
Main application	Joints, tendons, fascia	Spine, Hip Joint
Depth	Up to 6-8 cm	Any

In the MIBRAR method, both systems are used depending on the location: Sono Control Arm for joints and tendons, Cyber Navi Hand for the spine.

Precision without radiation

Sono Control Arm - every cell reaches the right place.

Questions

What is Sono Control Arm?

Ultrasound navigation system with mechanical stabilizer for precise injection of medications into joints and tendons. Real-time visualization without X-ray.

How does it differ from regular ultrasound?

The mechanical stabilizer fixes the transducer and needle guide. Eliminates tremor, ensures stable visualization. Injection accuracy over 98%.

Is it painful?

No. The procedure is performed under local anesthesia. Ultrasound allows visualization of nerves and avoidance of them. Most patients describe the sensation as minimal discomfort.

When to use Sono Control Arm and when Cyber Navi Hand?

Sono Control Arm: joints, tendons, fascia, superficial structures. Cyber Navi Hand: spine, hip joint, deep structures. The choice depends on the location.
