Ultrasound-Guided Regenerative and Orthobiologic Therapy for Hypermobile Ehlers-Danlos Syndrome

Your ability to perform physical tasks and activities depends on a biomechanical lever system, where muscle pulls against bone at the joints to generate rotational torque that produces movement. The architecture of a particular joint dictates its range of motion, supported by tough inelastic ligaments that attach bone to bone, and by biotensegrity – a […]

Fascial Dysregulation in Joint Hypermobility Disorders

Hypermobility spectrum disorders (HSDs) include a range of complex multisystem connective tissue disorders that affect joint stability. People with hypermobile joints are prone to pain, loss of balance, and increased risk of injury. Ligament laxity is often blamed for joint hypermobility, but new research is shining the spotlight on fascia’s role in joint instability.

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.
