From the Research

Treatment Options for Non-Displaced Radial Styloid Fracture

  • The use of a thumb spica splint for a non-displaced radial styloid fracture is not directly addressed in the provided studies, but we can look at the treatment options for similar fractures.
  • For non-displaced scaphoid fractures, studies suggest that a short arm cast or a short arm thumb spica cast can be used for immobilization 1.
  • However, one study found that wrist immobilization is crucial for non-displaced scaphoid waist fractures, and short arm casting was just as effective as thumb spica casting in preventing fracture displacement 1.
  • For non-displaced distal radial fractures, a study found that a shorter period of immobilization (3 weeks) can lead to better functional outcomes compared to a longer period of immobilization (5 weeks) 2.
  • Another study reviewed the use of upper-extremity orthoses and casts after injuries to the wrist and hand, and found that removable orthoses can be an effective treatment method for many common upper-extremity injuries, including non-displaced scaphoid fractures 3.

Immobilization Protocols

  • Immobilization protocols for non-displaced fractures have included the elbow, wrist, and thumb, but the effectiveness of thumb immobilization in preventing motion at the fracture site is not clear 1.
  • One study found that immobilization of the thumb does not make a significant difference in preventing motion at the scaphoid fracture site 1.
  • However, another study suggested that initial immobilization in a non-removable short-arm thumb spica cast may be recommended for non-displaced scaphoid fractures 3.

Alternative Treatment Options

  • Alternative treatment options for radial styloid fractures include magnesium bioabsorbable screw fixation, which may eliminate the need for implant removal due to symptomatic hardware 4.
  • However, this treatment option is not directly related to the use of a thumb spica splint, and more research is needed to determine its effectiveness for non-displaced radial styloid fractures.
