Tendon rupture after local steroid injection.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Rheumatology

Background:

• Corticosteroid injections are frequently used for localized inflammation.
• Depot steroids provide sustained release, but potential complications require investigation.

Observation:

• A case series of 13 patients experiencing 15 tendon ruptures following corticosteroid injections.
• Ruptures occurred in Achilles, supraspinatus, biceps (long head), and anterior tibial tendons.
• Triamcinolone hexacetonide was the most common steroid used, often mixed with local anesthetics.

Findings:

• Tendon ruptures are a significant complication of depository steroid injections.
• Eight of the 13 patients required surgical repair for their ruptured tendons.
• Older patients with biceps tendon ruptures were less likely to undergo surgery.

Implications:

• Clinicians should carefully consider the risks of tendon rupture when prescribing depository steroid injections.
• Developing preventative strategies for steroid-induced tendon injuries is crucial.
• Further research is needed to elucidate the mechanisms and optimize treatment for this complication.
