10 Reasons Good Posture Matters More than You Think

There is more to good posture than how you look in the mirror. Your body is a biomechanical system of levers, much like a machine. In order for all your parts to move efficiently, without friction, they must be perfectly tuned and aligned. When one or more joints are misaligned, they impact the entire organism, […]

Advanced Therapy for Proximal Hamstring Tendinopathy

Proximal Hamstring Tendinopathy (PHT), sometimes called high hamstring tendinopathy, is a condition involving the upper hamstrings where they attach to the ischial tuberosity – aka sitbones – at the base of the pelvis. PHT is a common sports injury associated with repetitive overuse, but it can also affect sedentary non-athletes, often from excessive sitting or […]

Getting to the Bottom of Tailbone Pain (Coccydynia)

Tailbone pain, clinically called coccydynia, describes pain and discomfort surrounding your coccyx – the small triangular bone at the base of your spinal column. Acute pain can arise after a fall on your bottom, often involving a coccyx bruise or fracture, or it can develop gradually from certain conditions and activities. We answer your questions […]

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
