Objective: Several lower limb tendinopathy treatment modalities involve identification of pathological paratendinous or intratendinous neovascularisation to target proposed co-location of painful neoneuralisation. The ability to reliably locate and assess the degree of neovascularity is therefore clinically important. The Modified Ohberg Score (MOS) is frequently used to determine degree of neovascularity, but reliability has yet to be established among Sport and Exercise Medicine (SEM) consultants...

Spontaneous bilateral quadriceps tendon rupture is a rare finding in emergency departments. Thus, the pathophysiology is not well understood. Imaging for improved speed of diagnosis is rarely considered. We present a case of non-traumatic spontaneous bilateral quadriceps tendon rupture and examine current literature on the pathophysiology and imaging guidelines on the topic. The patient is a 49-year-old male that presented to the emergency department with bilateral thigh pain. He had been seen earlier with similar pain, but now presents with increased difficulty ambulating...

This Institutional Review Board-approved pilot study attempted to detect the correlation between ultrasound shear wave elastographic measures and tendon loads. Five male fresh-frozen cadaveric Achilles tendons were loaded in 10-N increments from 0 to 60 N. Shear wave velocity measurements within each Achilles tendon were obtained at each load in longitudinal and transverse orientations. Shear wave velocity measurements were correlated with tendon tension on both longitudinal and transverse plane imaging and showed moderate and strong positive correlation coefficients, respectively...

Isolated avulsion fracture of the extensor carpi radialis longus (ECRL) tendon is a rare and poorly understood injury. We present a unique case of a 45-year-old male who fell on his flexed right hand. He presented with a subtle but extremely painful mass on the dorsum of his wrist. Ultrasound (U/S) imaging of the mass revealed an avulsed bone fragment attached to the ECRL tendon, confirming the clinical suspicion of an ECRL avulsion injury. Computed tomography and magnetic resonance imaging are well-documented imaging modalities to detect tendon avulsions...

Office-based ultrasonography has become increasingly available in many settings, and its use to guide joint and soft tissue injections has increased. Numerous studies have been conducted to evaluate the use of ultrasound-guided injections over traditional landmark-guided injections, with a rapid growth in the literature over the past few years. A comprehensive review of the literature was conducted to demonstrate increased accuracy of ultrasound-guided injections regardless of anatomic location. In the upper extremity, ultrasound-guided injections have been shown to provide superior benefit to landmark-guided injections at the glenohumeral joint, the subacromial space, the biceps tendon sheath, and the joints of the hand and wrist...

Rheumatod arthritis is a chronic systemic autoimmune disease, characterized by inflammation in joints and tendon sheaths, which frequently leads to permanent and serious disability due to joint destruction, but also tendon and ligament ruptures. Clinical management of rheumatoid arthritis has traditionally been supported by biochemical and radiographic findings. However, imaging modalities like ultrasound and magnetic resonance imaging (MRI) have improved the possibility for better management of rheumatoid arthritis patients, due to higher sensitivity and specificity for detecting ongoing inflammation, this thesis is focusing on tenosynovitis as recent studies have shown that inflammation in tendon sheaths, i...

The term Rehabilitative Ultrasound Imaging (RUSI) refers to the use of ultrasound imaging by physiothera-pists. Ultrasound is used by physiotherapists to evaluate the morphology of muscles and other associated soft tissues not only at rest but also for a dynamic assessment of those structures during physical activities and tasks. RUSI is most commonly utilized as part of a biofeedback mechanism, which shows good efficacy in lower back pain treatment. Several possibilities have been also described for clinically adapting this method in the rehabilitation of the shoulder and knee and postoperative improvement of tendons...

PURPOSE: To determine the accuracy of ultrasound-guided (UG) injections compared with anatomic landmark-guided (AL) injections in the first dorsal compartment (FDC) with the hypothesis that ultrasound guidance would increase the accuracy of injection. METHODS: We randomized 43 above-elbow cadaveric specimens to receive latex dye injections into the FDC via a UG or AL technique. If ultrasound imaging identified a septated FDC, the needle was redirected and a portion of the dye was injected around the extensor pollicis brevis (EPB) tendon...

We report our experience with 6 patients who had total knee replacements with lateral-sided knee pain, referred for ultrasound (US) assessment and US-guided injection. All cases showed an osteophyte within the popliteus sulcus of the lateral femoral condyle impinging on the adjacent tendon. Five of 6 patients reported improvement of symptoms immediately after US-guided injection of an anesthetic and a steroid. Ultrasound has a unique role in the imaging of knee replacements because of its real-time capabilities and absence of artifacts at the popliteus tendon origin...
