From the Guidelines
The treatment for a nondisplaced fracture of the distal tubercle of the scaphoid bone typically involves simple immobilization, as this type of fracture is usually small, nonarticular, or minimally displaced. This approach is supported by the American College of Foot and Ankle Surgeons, as noted in a study published in the American Family Physician in 2002 1. The immobilization method can include a short arm thumb spica cast or a removable thumb spica splint for 4-6 weeks, allowing the fracture to heal while minimizing movement at the fracture site.
Key considerations for managing this type of fracture include:
- Immobilization to prevent further injury and promote healing
- Regular follow-up with radiographs at 2-3 week intervals to ensure proper healing
- Pain management using acetaminophen or NSAIDs like ibuprofen for the first 1-2 weeks
- Transition to a removable splint after 2-3 weeks if pain is decreasing, to allow for comfort while still protecting the fracture site during activities
- Initiation of physical therapy focusing on range of motion and strengthening exercises after immobilization is discontinued to restore function
It's crucial to note that surgery is rarely needed for nondisplaced distal tubercle scaphoid fractures, unless complications such as significant displacement, delayed union, or persistent symptoms after conservative treatment arise. The excellent blood supply to the distal part of the scaphoid bone contributes to the generally good prognosis for these fractures, with lower rates of nonunion and complications compared to more proximal scaphoid fractures. Therefore, conservative management with immobilization and supportive care is the preferred initial treatment approach for nondisplaced fractures of the distal tubercle of the scaphoid bone, as supported by the available evidence 1.
From the Research
Treatment Options for Nondisplaced Fracture of the Distal Tubercle of the Scaphoid Bone
- Nonsurgical treatment with cast immobilization is recommended for stable, nondisplaced fractures of the scaphoid bone 2, 3, 4, 5
- A short arm-thumb spica cast is a common type of cast used for immobilization 2
- Percutaneous screw fixation is an alternative treatment option for nondisplaced or minimally displaced scaphoid fractures 2, 6
- Operative fixation of nondisplaced fractures may be considered in patients who prefer to avoid prolonged cast immobilization 3, 6
- Conservative treatment with cast immobilization can be effective in achieving union rates similar to those attained with operative intervention for nondisplaced scaphoid fractures 4
Duration of Cast Immobilization
- A restricted period of cast immobilization, typically 6 weeks, is usually adequate for the treatment of non-displaced scaphoid fractures 5
- Some cases may require a longer period of cast immobilization, up to 8-12 weeks 5
