Peesruptuur na injectie van corticosteroïden in ganglioncyste

Background

Although corticosteroid injections are frequently used in practice to treat tendinopathies, there are many adverse effects.

Case description

A 62-year-old woman received an aspiration and corticosteroid injection of a ganglion on the volar side of the left wrist. A few weeks later, she presented with severe pain and loss of function of the left wrist. On physical examination, here was a notable swelling with hematoma formation, along the course of the flexor carpi radialis. An MRI confirmed complete rupture of the flexor carpi radialis (FCR) tendon. She was treated non operatively with analgesics and a protective brace. During final check-up minimal loss of function was seen.

Conclusion

Cautiousness and judicious restraint are imperative when considering corticosteroid infiltrations targeting a volar ganglion at the level of the FCR. Aspiration combined with corticosteroid infiltration is not recommended for patients exhibiting (subclinical) STT-/CMC-1 osteoarthritis, as it may cause FCR tendon ruptures.
