The radiocarpal joint is a synovial articulation between the distal radius and the proximal carpal row (scaphoid, lunate, and triquetrum).
The radiocarpal joint is a synovial articulation between the distal radius and the proximal carpal row (scaphoid, lunate, and triquetrum). Ultrasound-guided injections into the radiocarpal joint are performed for arthritis, synovitis, and for diagnostic purposes. Providers will position the patient with their wrist pronated in front of them and resting on a chuck or pillow with the wrist in slight flexion.
Position and guidance of radiocarpal injection Providers can use either a hockey stick or linear transducer. The probe will be placed longitudinally across the radioscaphoid joint. The best way to find the joint is to find Lister’s tubercle and then rotate the probe 90 degrees until the radiocarpal joint is seen in long axis.
Lister’s tubercle on ultrasound The ultrasound screen will show the distal radial epiphysis and the first carpal row. This location will allow the needle to pass between the second and third extensor compartment. Ultrasound image of radiocarpal joint Then, using a 25 or 27 gauge 1.5-2inch needle, it should be guided in plane from distal to proximal into the radiocarpal joint.
Typical volume injected into the radiocarpal joint is 1mL. Wrist arthritis is commonly seen as a source of wrist pain. These patients are candidates for a radiocarpal joint injection, which has been discussed in the post above.

If you are experiencing symptoms that may be related to ultrasound guided radiocarpal injection technique, 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.
