Abstract

Objectives
Conservative treatment for distal radius fractures typically involves closed reduction and immobilization with a plaster cast. However, no consensus exists regarding the best method and duration for immobilization. This study investigated the functional outcomes associated with different plaster cast application techniques in the treatment of stable distal radius fractures.
Methods
A systematic search was performed in accordance with PRISMA guidelines for studies in the last 5 years. The inclusion criteria were randomized controlled trials that investigated non-operative treatments for distal radius fractures. We excluded studies with short-term follow-up (less than 3 months), ongoing trials, those that did not directly address fractures, and studies involving the use of sugar-tong splints or non-circular immobilization. The outcomes evaluated included subjective measures (Disabilities of the Arm, Shoulder and Hand score; Patient-Rated Wrist Evaluation score; Mayo Wrist Score; and visual analog scale) and objective outcomes (complication rate and radiological parameters).
Results
We included seven articles from 2017 to 2022. These studies reported a total of 542 fractures, predominantly in women, with a mean age of over 50 years. Both short and long arm casts demonstrated similar functional and radiological outcomes. A longer immobilization period (>3 weeks) should be considered to prevent re-displacement.
Conclusion
In stable fractures treated conservatively, the use of both short and long arm casts resulted in comparable functional outcomes in older patients. Immobilization for at least 3 weeks is recommended, as it provided similar clinical and radiological outcomes compared to longer periods of immobilization (level of evidence: 2A).
