Musculoskeletal Ultrasound


It would be nice if athletic injuries were simple, clean and easy to diagnose. However, most athletic injuries occur during play, involving large force loads at high velocities, often resulting in complex injuries to multiple structures.

Traditionally, X-Ray and MRI have been used to assess and diagnose sports injuries. However, those methods have several limitations, and results can take hours or even days while the images are read and interpreted. Meanwhile, athletes and coaches are left guessing about the extent and severity of an injury, and treatment is delayed.

Advantages of Ultrasound Imaging

Musculoskeletal Ultrasound (MSUS) delivers high frequency sound waves to the injured area, which bounce back as images that can be viewed on a computer monitor. Soft tissue damage precedes hard tissue changes, and MSUS is all about soft tissues. MSUS provides pictures of muscles, tendons, ligaments, joints, internal organs, neural bodies and blood vessels in real time. Moreover, MSUS can detect stress fractures to bones earlier than X-ray or MRI.

Unlike X-ray or MRI, MSUS equipment is lightweight and portable, enabling accurate diagnosis to be done within minutes after the injury occurs. Moreover, the images can be viewed in real time by both clinician and patient, enabling the patient to participate in the diagnostic process.


Advantages of MSUS over X-Ray, CT and MRI include:

Ultrasound is safe and can be used on anyone. Because X-ray and CT scan emit radiation, the amount of exposure per year is limited, and those methods cannot be used on pregnant females, and in certain other cases. MRI does not emit radiation, and it can provide details of soft tissues, but because it uses large magnets, it cannot be used on patients with metal implants or pacemakers, during pregnancy, or in other less common cases. Because of its safety, MSUS can be used repeatedly over a short period of time.

A high-end MSUS transducer can provide more details than other imaging methods, providing a clearer view of abnormalities like tendon tears. MSUS’s higher resolution makes it more effective for detecting small calcifications and tiny foreign bodies.

MSUS provides an extended field of view. Due to the elastic nature of soft tissue, sonoelastography can assess the response of tissue to stress (pressure), to visualize stiffness that can indicate tissue damage or pathology. Elastography can be used to predict recovery time following treatment, and to help assess a patient’s readiness to return to activity, based on a normal tendon elastogram. Doppler imaging can detect inflammatory changes earlier than blood work or MRI.

Dynamic real time MSUS imaging is interactive, enabling the examination to be directed to the exact location of a patient’s pain or discomfort. During interactive examination, the patient is able to produce movements that cause pain, giving the examiner greater insight into the nature and location of injury. Movement can reveal joint abnormalities and impaired movement in tendons, bursa, muscles and joints.

MSUS is more comfortable for the patient, who is not subjected to prolonged immobilization in a claustrophobic tunnel as with MRI.

The patient is able to provide valuable feedback during MSUS in response to palpation and movement. When a painful area is detected, associated abnormalities can often be seen on the monitor, confirming diagnosis. The patient’s feedback can provide vital information that may reveal tendon or joint subluxation, or ligament incompetence.

Rapid results: Since MSUS diagnosis is performed in real time, both patient and clinician can receive immediate results and begin to devise a treatment strategy in the same session.

Ultrasound waves provide high resolution images of tendon tissue, which is hyperechoic, making MSUS the method of choice for distinguishing between partial- and full-thickness tendon tears. It is also useful for depicting tendon subluxation and calcific tendonitis, and for evaluating tendons of the feet and ankles.

Guided aspirations: Ultrasound provides a useful tool for performing accurate real-time guided injections or aspirations.

Blood flow: MSUS can detect changes in blood flow that can help the clinician pinpoint an injured area.

Bilateral imaging: With MSUS, the clinician can quickly and easily view images of both sides of the body during the same session, to compare the patient’s injured structures to bilateral “normal” structures.

MSUS allows for a dynamic view of the entire length of a structure. The transducer can follow the entire pathway of a nerve to identify the specific point at which it is compressed. It can follow a long muscle like a hamstring from origin to insertion to pinpoint the precise location and nature of an injury.

MSUS can detect the presence and behavior of cystic masses.

Both MRI and MSUS provide superior imaging over X-ray, and they are similar in sensitivity and specificity. However, in addition to the advantages listed above, the cost of MSUS is a small fraction of MRI, and the equipment requires very little space compared to MRI.


Ultrasound Imaging for Diagnosis and Treatment of Athletic Injuries

For athletes, early and accurate diagnosis and treatment means sooner return to play. Not only does MSUS allow for diagnosis within minutes of injury, but it provides an important tool for assessing the progress of rehabilitation, and for determining whether an athletic injury has healed sufficiently for the athlete to safely return to play.

Dr. Lev Kalika, founder of NYCSPT, has personally studied with some of the world’s most prestigious experts in diagnostic ultrasonography, including Carlo Martinolli MD,PhD , Alexander Kinzersky MD PhD , Thomas Clark DC, RMSK, Anna Vovchenko MD, and Rostislav Bubnov MD, PhD. Over the past seven years, Dr. Kaika has attended MUSOC, EFSUMB, AIUM and Gulfcoast Ultrasound Institute. He is an active member of the American Institute of Ultrasound in Medicine (AIUM), and is currently developing his own unique approach to Dynamic Functional Ultrasonography. Dr. Kalika is also in process of organizing a post graduate education school for physiotherapists, sports medicine physicians and chiropractors.

Dr. Kalika’s services are frequently sought out by elite athletes for rehabilitation and performance enhancement.
