Oxytocin-induced tenosynovitis and extensor digitorum tendon rupture

Area of Science:

• Orthopedic Surgery
• Musculoskeletal Disorders
• Pharmacology

Background:

• Oxytocin is a commonly used medication in obstetrics and gynecology.
• Aseptic tenosynovitis is a non-infectious inflammation of the tendon sheath.
• Tendon rupture is a serious condition requiring surgical intervention.

Observation:

• A rare case of aseptic tenosynovitis occurred following an oxytocin injection near a tendon.
• The inflammation was localized to the vicinity of the extensor digitorum communis tendon.
• The patient experienced a spontaneous rupture of the extensor digitorum communis tendon.

Findings:

• Oxytocin injection can trigger aseptic tenosynovitis as a rare adverse event.
• Aseptic tenosynovitis in close proximity to a tendon can lead to spontaneous tendon rupture.
• This case highlights a potential iatrogenic cause of extensor digitorum communis tendon rupture.

Implications:

• Clinicians should be aware of the potential for aseptic tenosynovitis from oxytocin injections.
• Early recognition and management of oxytocin-induced tenosynovitis may prevent tendon rupture.
• Further investigation into the mechanism of oxytocin-related tendon injury is warranted.
