Anterior Cruciate Ligament Prevalence, Epidemiology, and Definitions Injury to the anterior cruciate ligament (ACL) represents the most important ligament injury around the knee. It is relatively uncommon in the general population but is an important cause of injury in individuals…
Introduction Ultrasound machines with high-resolution probes are readily available in most radiology departments and are routinely used to assess both articular and periarticular disorders. They are also becoming commonplace in rheumatology departments, reflecting the important role they now play in…
Shoulder Intervention Subacromial Subdeltoid Bursa Injection Patient and Probe Position Ultrasound-guided injections provide more reliable and accurate needle placement which is particularly useful to assess the diagnostic response to local anaesthethic in patients with a poor response to a previous…
Introduction The superficial location of many musculoskeletal structures makes them readily amenable to injection therapy and many unguided injections are carried out in the office or ward setting. Large superficial structures are easily targeted, although success will vary with the…
Introduction Due to the superficial location of many of the structures that contribute to medial sided symptoms, ultrasound plays an important role in their assessment. Abnormalities of the medial tendons predominate, but disorders of the neurovascular structures, ligaments and even…
Tendons Tibialis Anterior Anatomy The tibialis anterior tendon is the strongest of the anterior ankle tendons. Its parent muscle arises from the upper two-thirds of the lateral aspect of the tibia. It has a high musculotendinous junction and a strong…
Introduction The most common symptoms leading to an ultrasound examination of the posterior ankle region are those associated with disorders of the Achilles tendon or the plantar aponeurosis (heel pain and/or swelling). In an acute setting, ultrasound is most often…
Introduction Ultrasound examination of the ankle and foot is one of the most common examinations in musculoskeletal ultrasound. The superficial location of most structures means that ultrasound plays an important role in the management of many patients with painful conditions…
Overview As with other larger joints, ultrasound is most useful when the patient's symptoms are localized to a relatively specific area. More diffuse symptoms suggest internal derangement due to meniscal, cruciate and cartilage injuries. These are diagnosed by MRI with…
Developmental Dysplasia of the Hip Developmental dysplasia of the hip (DDH) is a disorder where under development of the acetabulum leads to reduced femoral head coverage which, in turn, predisposes to acetabular labral abnormalities and early cartilage disease. If uncorrected,…
