Summary
Mallet thumb injuries, though uncommon, can cause significant difficulty. Non-operative treatment for acute closed mallet thumb injuries yields satisfactory outcomes, restoring full range of motion.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- Mallet thumb injuries, specifically avulsion injuries of the extensor pollicis longus, are infrequent but can lead to considerable functional impairment.
- These injuries typically result from hyperflexion trauma to the thumb.
Observation:
- A case study involved a 55-year-old male with a closed hyperflexion thumb injury presenting with pain and inability to actively extend the thumb.
- Clinical assessment and radiographic imaging confirmed a soft-tissue mallet injury.
Findings:
- The patient underwent non-operative management, involving immobilization of the thumb's interphalangeal joint.
- Successful treatment resulted in the patient regaining a full range of motion in the affected thumb.
Implications:
- Non-operative management is a viable and effective treatment strategy for acute, closed mallet thumb injuries.
- Prompt non-operative intervention in acute cases can lead to favorable functional recovery and satisfactory patient outcomes.
