Diagnostic ultrasound of the wrist and hand Moving forward in our ultrasound series after the shoulder and elbow, the wrist and hand diagnostic scan will be covered in this week’s post. The superficial nature of the complex, small anatomical structures of the hand and wrist lend themselves well to ultrasound (US) evaluation. Ultrasound allows confirmation of the diagnosis and can distinguish solid from cystic lesions.
It allows the operator to determine the anatomical relationships of the mass and thus avoid critical structures, such as blood vessels and major nerves. US guidance can also help the operator to avoid biopsy of necrotic or atypical areas within the lesion. By optimising the needle position US guidance therefore increases the chances of a successful outcome.
Case Vignette You are performing a diagnostic ultrasound of a wrist to evaluate for carpal tunnel syndrome. What is the most radial tendon located in the carpal tunnel? A) Flexor carpi radialis B) Flexor pollicis longus C) Flexor digitorum profundus D) Flexor digitorum superficialis The patient and sonographer should be seated opposite or 90 degrees to each other, with the patient’s hands resting on the examination table.
Supporting the area with a rolled towel may help expose the areas of interest. Higher frequency transducers should be used if available with either hockey stick or linear probes. In the hand and wrist, focused examinations targeted to answer the clinical question are usually performed.
This includes scanning the relevant structures in at least two orthogonal planes, with dynamic and Doppler assessment. When in doubt, comparison can be made with the contralateral side. Dorsal wrist ultrasound positioning.
If you are experiencing symptoms that may be related to diagnostic wrist and hand ultrasound, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
