Laboratory Studies
- Costochondritis has no confirmatory or diagnostic laboratory tests.
Imaging Studies
- Imaging studies are unnecessary to confirm a diagnosis of costochondritis.
- Chest radiography may exclude other possible causes of chest pain but offer no diagnostic value to costochondritis assessment. In the absence of confounding physical findings, the diagnostic yield of a chest radiograph is less than 2%.
- In the unusual circumstance that imaging is required, CT scanning is probably the best choice because it can demonstrate swelling of the costal cartilage. Ultrasonography may also demonstrate swelling but is less useful. Bone scanning may demonstrate uptake at the area of concern; however, increased uptake at costochondral junctions that do not produce symptoms may also be present, making this modality less useful.
Procedures
- Costochondral joint injection is indicated for patients with severe pain for whom oral analgesics are either ineffective or contraindicated. Costochondral joint injection may have a role in treating refractory cases of costochondritis. Using a 22-gauge needle, inject 2% lidocaine or a combination of corticosteroid and lidocaine. A total volume ranging from 1-3 mL may be injected depending on patient size.
- Contraindications include an uncooperative patient, known hypersensitivity to the injectant, unclear diagnosis, or unstable cardiopulmonary disease. Use caution in patients with a severe coagulopathy. Complications include bleeding, infection, and pneumothorax.
- Manipulation using a high velocity, low amplitude technique has been described to produce relief in costochondritis, but no larger studies have been done to confirm this.
