Ultrasound-guided arthrocentesis and intra-articular injections of the radiocarpal and tarsocrural joints in the dog

For arthrocentesis, ultrasound guidance can maximize joint fluid volume acquisition for diagnostic purposes while avoiding blood contamination. For joint injections, ultrasound will help ensure intra-articular delivery of the injectate, particularly when synovial fluid aspirate feedback is inhibited (dry joint or obstructive synovial proliferation). Imaging guidance can help reduce iatrogenic tissue damage and procedure time.
