Sequential rupture of extensor tendons after a Colles fracture

Area of Science:

• Orthopedic Surgery
• Hand Tendon Injuries
• Traumatic Orthopedics

Background:

• Colles fractures are common wrist injuries that can lead to complications.
• Tendon ruptures, though less common, can occur after fractures.
• Understanding the mechanisms of tendon failure is crucial for patient outcomes.

Observation:

• A patient experienced extensor pollicis longus tendon rupture 6 weeks post-Colles fracture.
• Successful treatment involved a tendon transfer procedure.
• Subsequently, spontaneous rupture of the extensor digitorum communis tendon to the long finger occurred 10 months after the initial injury.

Findings:

• The initial extensor pollicis longus tendon rupture was successfully managed with tendon transfer.
• A delayed, spontaneous rupture of a different extensor tendon (extensor digitorum communis) was observed.
• The underlying etiology for both tendon ruptures could not be definitively identified.

Implications:

• This case highlights the potential for delayed and spontaneous tendon ruptures following wrist fractures.
• Further investigation may be needed to elucidate the biomechanical or biological factors contributing to such ruptures.
• This underscores the importance of vigilant monitoring for tendon complications after Colles fractures.
