Guiding Musculoskeletal Procedures

A method comprising:

• providing a syringe device having a single needle, a first syringe comprising saline with microbubbles, a second syringe configured to aspirate fluid from a treatment site of a patient, and a connector coupling the single needle to the first syringe and to the second syringe;
• guiding the single needle to the treatment site;
• injecting, with the first syringe, a quantity of saline with microbubbles;
• confirming a desired position of the single needle, with ultrasound imaging, by identifying the microbubbles in the quantity of saline relative to a tip of the single needle and further relative to one or more anatomical landmarks visible with the ultrasound imaging;
• and
• aspirating, with the second syringe, fluid from the treatment site.

A method comprising:

• providing a syringe device having a single needle, a first syringe comprising saline with microbubbles and having a first-syringe plunger, a second syringe having a second-syringe plunger that is independently operable relative to the first-syringe plunger, and a connector coupling the single needle to the first syringe and to the second syringe;
• guiding the single needle to a treatment site of a patient;
• injecting, with the first syringe, a quantity of saline with microbubbles;
• confirming a desired position of the single needle, with ultrasound imaging, by identifying the microbubbles in the quantity of saline relative to a tip of the single needle and further relative to one or more anatomical landmarks visible with the ultrasound imaging;
• and
• with the second syringe, injecting a therapeutic compound at the treatment site or aspirating fluid from the treatment site.
