Arthrographie

CT
Arthrografie oberes Sprunggelenk: Injektion von Kontrastmittel (ca. 3 bis 4 ml 1 / 1 mit NaCl verdünnt) über einen ventralen Zugang lateral der Sehne des M. tibialis anterior auf Höhe des Sprunggelenkspaltes. Der Knorpeldefekt an der medialen Talusschulter demarkiert sich gut.


Arthro-CT
(wegen störendem Metall in Patella nach Fraktur kein MRT) mit drittgradiger Chondromalazie retropatellar und femoral

Arthrografie
und CT-Arthrografie Ellenbogen mit Radiusköpfchenfraktur und Abscherung eines chondralen Flakes am Capitulum humeri: Die Injektion erfolgte von dorsal (ca. 4 ml). Der Knorpelüberzug ist gegen das röntgendichte Kontrastmittel gut abgrenzbar.

KM-Injektion
für CT-Arthrographie Kniegelenk: Unter sterilen Kautelen wird über einen Zugang von lateral am kranialen Rand der Patella nach retropatellar eingestochen. Das Zielvolumen beträgt beim Kniegelenk ca. 40 ml, wobei ein evtl. bestehender Gelenkerguss berücksichtigt werden muss. Wenn kein Gelenkerguss vorhanden ist, kann das Kontrastmittel mit NaCl (ca. 3 zu 1) verdünnt werden.

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Intra-articular injection in a right hip joint under fluoroscopic guidance. Puncture site (white arrow) is at the superior part of the anatomical neck of the femur but the middle part could have been chosen (white arrowhead)

An arthrogram (or arthrography) is a commonly performed procedure in musculoskeletal radiology, which can refer to both an injection into a joint, and cross-sectional imaging after a joint is injected.
Indications
Arthrograms are performed for a variety of indications including:
- labral tear after shoulder dislocation
- hip labral tears
- partial-thickness tendon tears
- partial-thickness ligament tears
- hand ligament tears
- retear of repaired tendon
- retear of repaired meniscus
- pain relief
- surgical planning
Arthrogram injections
Three main categories of injections are performed:
- MR arthrogram
- a detailed assessment of intra-articular structures
- provides excellent soft-tissue contrast and edema patterns
- in older patients may not be necessary as labral tears and arthropathy are common
- CT arthrogram
- can give a detailed assessment of intra-articular structures
- an alternative in those who can not have an MRI
- involves radiation and soft tissue contrast less than MRI
- anesthetic arthrogram
- performed for therapeutic and/or diagnostic reasons
- provide image-guided intra-articular injections
- excess use of corticosteroid and local anesthetics could cause chondral loss
