Article
Sternoclavicular joint injection (technique)
Sternoclavicular joint (SCJ) injections under image guidance ensure precise delivery of an injectate into the joint and, importantly, that the needle is under direct visualization.
Indications
pain
arthropathy, e.g. osteoarthritis
diagnostic injection
Contraindications
Absolute
anaphylaxi...

Epidural blood patch
Epidural blood patches are a treatment option for patients with craniospinal hypotension or post-dural puncture headaches in which small volumes of autologous blood are injected into a patient's epidural space to stop cerebrospinal fluid leak. The procedure can be done blind or under imaging (fl...
Article
Hip joint injection (technique)
Hip joint injections can be performed with a variety of image guidance, including fluoroscopy and ultrasound, which are used to administer MRI arthrogram injectate, or a steroid containing anesthetic arthrogram injectate.
Indications
MRI: labral injury
anesthetic
pain/arthropathy, e.g. ost...

Sacroiliac joint injection
Sacroiliac joint injections can be performed using a posterior approach into the sacroiliac (SI) joint under fluoroscopic or CT guidance. It is often performed bilaterally.
Indications
diagnostic: relief of pain after injection of local anesthetic
therapeutic: to relieve pain from degene...
Article
MR arthrogram solution
MR arthrogram solution is a gadolinium-containing mixture injected into a joint for MR arthrography.
Terminology
Fluoroscopy, ultrasound or CT guidance can be used to cannulate a joint, which is then injected with the MR arthrogram solution. MR arthrogram solutions differ in different instit...

Rotator cuff calcific tendinitis barbotage
Rotator cuff calcific tendonitis can be treated with various techniques including ultrasound-guided barbotage, which is also known as ultrasound-guided needling and lavage. It is often performed in conjunction with a subacromial bursal injection. Alternative treatments include extracorporeal sho...
Article
Pudendal nerve block (technique)
Pudendal nerve blocks are performed on those with suspected or proven pudendal neuralgia. Using CT will ensure accurate needle placement, which aims for a perineural pudendal nerve injection in the pudendal canal, also known as Alcock's canal.
Indications
pudendal neuralgia
diagnostic
Contr...
Article
Acromioclavicular joint injection (technique)
Acromioclavicular joint (ACJ) injections under image guidance ensure precise delivery of an injectate into the joint. Ultrasound allows for real-time visualization of the needle and administration of the injectate. Fluoroscopy is an alternative method of image guidance.
Indications
pain: a...
Article
Symphyseal cleft injection
Symphyseal cleft injections (symphysography) are performed as both diagnostic and therapeutic measures for patients with (suspected) osteitis pubis, usually under CT or fluoroscopy.
Indications
suspected or confirmed osteitis pubis

Glenohumeral arthrography
Glenohumeral (shoulder) arthrography is an imaging technique used to evaluate the glenohumeral joint to evaluate the joint components. A glenohumeral joint injection is usually performed under fluoroscopic guidance although ultrasound and CT can be also be used. An alternative to direct arthrogr...
Article
Greater trochanteric bursa injection (technique)
Greater femoral trochanteric bursa injections under ultrasound guidance ensure the injectate is accurately given into the bursa. The greater trochanteric bursa is the largest of the bursae surrounding the proximal femur, with the others including the subgluteus minimus and subgluteus medius burs...
Article
Gluteus minimus/medius calcific tendinopathy barbotage (technique)
Gluteus minimus/medius calcific tendinopathy barbotage is a procedure performed under ultrasound guidance with the aim of reducing the bulk of tendon calcification, in a similar fashion to that performed for rotator cuff calcific tendinopathy.
Indications
gluteus minimus/medius tendon calcifi...

Angioleiomyoma
Angioleiomyomas, also known as angiomyomas or vascular leiomyomas, are benign pericytic or perivascular soft tissue tumors.
Epidemiology
Angioleimyomas are rare and have been observed in a wide age range with a peak in the 4th to 6th decades of life. Generally, women are more commonly affect...

Ulnar nerve block (ultrasound-guided)
Ulnar nerve blocks are an approach for delivering anesthesia to the ulnar nerve territory either as a standalone blockade or combined with brachial plexus, radial or median nerve block.
Indications
burns involving tissue in the ulnar nerve territory
rescue analgesia for failed brachial plexus...
Article
Radial nerve block (ultrasound-guided)
Radial nerve blocks are a procedure for delivering anesthesia to the radial nerve territory either as a standalone blockade or in conjunction with a brachial plexus, ulnar or median nerve block.

forearm and hand surgical ...
Article
Arthrogram (CT)
A CT arthrogram is a CT performed after a joint is injected with a solution containing iodinated contrast. They are not commonly abbreviated as CTA, which will be confused with CT angiography. An arthrogram also refers to the procedure of injecting a joint.

Arthrocentesis
Arthrocentesis or joint aspiration is an interventional procedure done for the collection of synovial fluid.
History
The existence of liquid inside joints was first mentioned in the Corpus Hippocraticum, later in the 16th century, Paracelsus coined the name “synovia” for synovial fluid.
Indic...
