What is the difference between vertebroplasty and kyphoplasty? The key difference is that vertebroplasty is used to treat vertebral body compression fractures by directly instilling cement via a thin needle cannula into the fracture under high pressure, while kyphoplasty first uses a balloon catheter at the site of the fracture to actively restore the lost …

What is calcific tendinosis lavage? Calcific tendinosis lavage is a percutaneous method of treating symptomatic calcium hydroxyapatite deposition that is refractory to conservative treatment. This procedure is most commonly performed for the treatment of calcific tendinosis in the rotator cuff. After local anesthesia is achieved, an 18 G needle is advanced into the calcium deposit …
What is tendon fenestration, and how is it performed? Tendon fenestration is a percutaneous US-guided therapeutic option for the treatment of chronic tendinosis. US is used to target the area of tendinosis. Then, an in plane approach longitudinal to the tendon is used to gently pass a needle through the abnormal portion of the tendon …
What is platelet rich plasma injection, and why is it used? PRP injection is a developing therapy for the treatment of tendon injuries. PRP is defined as a platelet concentration higher than that of healthy whole blood (typically five times that of whole blood). Platelets initiate the clotting cascade, and it is thought that increasing …
What are the potential complications of Baker cyst aspiration? Aspiration of the semimembranosus-medial gastrocnemius bursa, or Baker cyst, is a frequently performed bursal aspiration under US guidance, with or without corticosteroid injection. The fluid collection lies between semimembranosus muscle and the medial head of the gastrocnemius muscle and may be simple or complicated. One potential …

What techniques can help to increase the conspicuity of a needle during a Ultrasound guided procedure? There are several very helpful techniques that may improve visualization of the needle during deep US-guided procedures where the needle angle is steep in order to reach the target. The first is the jiggle technique, during which the operator …
in plane and out of plane needle approaches in Ultrasound guided interventions “In plane” and “out of plane” are two basic approaches to freehand US-guided procedures, which refer to needle trajectory relative to the transducer and sound beam. With an in plane approach, the needle is directed under the long axis or parallel to the …
