CPT4 code
Name of the Procedure:
Radiologic Examination, Ankle, Arthrography, Radiological Supervision and Interpretation
- Common Name(s): Ankle Arthrography
- Technical/Medi Terms: Radiologic Ankle Arthrography
Summary
Ankle arthrography is an imaging procedure where a contrast dye is injected into the ankle joint to enhance the visibility of the structures within, such as ligaments, cartilage, and the joint capsule, during X-ray or fluoroscopy. A radiologist supervises and interprets the images for diagnostic purposes.
Purpose
The procedure is used to diagnose and evaluate issues within the ankle joint, such as ligament tears, cartilage damage, or unexplained pain and swelling. The goal is to obtain clear images of the internal structures of the ankle to guide treatment decisions.
Indications
- Persistent ankle pain and swelling with unclear cause
- Suspected tears in ligaments or cartilage
- Evaluation of joint abnormalities detected in other imaging studies
- Preoperative assessment before joint surgery
Preparation
- Patients may be advised to avoid eating or drinking for a few hours before the procedure.
- Inform the doctor of any medications currently being taken.
- Removal of metal objects around the ankle area.
Procedure Description
- The patient is positioned on an X-ray table.
- The ankle is cleaned and prepped for injection.
- A local anesthetic is applied to numb the area.
- A contrast dye is injected into the ankle joint using a fine needle.
- X-ray or fluoroscopic images are taken from various angles while the radiologist supervises.
- The images are reviewed and interpreted to diagnose any abnormalities.
Duration
The procedure typically takes about 30 to 60 minutes.
Setting
Ankle arthrography is performed in a hospital's radiology department, outpatient clinic, or a specialized imaging center.
Personnel
- Radiologist
- Radiologic Technologist
- Nurse or Medical Assistant
Risks and Complications
- Pain or discomfort at the injection site
- Allergic reaction to the contrast dye
- Bleeding or infection at the injection site
- Temporary increase in joint pain following the procedure
Benefits
- Detailed images of the joint structures
- Precise diagnosis of joint problems
- Informed decision-making for subsequent treatments or surgeries
- Immediate interpretation by a specialized radiologist
Recovery
- Patients can usually go home shortly after the procedure.
- Ice packs and over-the-counter pain relievers can help manage any discomfort.
- Avoid strenuous activity for 24-48 hours post-procedure.
- Follow-up appointments may be scheduled to discuss the results and next steps.
Alternatives
- MRI or CT scans, which provide detailed imaging without the need for contrast injection.
- Ultrasound, which can image soft tissues without radiation exposure.
- Pros and cons should be discussed with the doctor, as some alternatives might not provide as detailed a view of the joint structures.
Patient Experience
- Mild discomfort or pressure during the dye injection.
- Possible soreness or bruising at the injection site afterward.
- Radiologist and medical staff will ensure comfort and manage any pain during the procedure.
