Topology-Optimized Splints vs Casts for Distal Radius Fractures: A Randomized Clinical Trial.

Article Synopsis
  • There is currently no evidence supporting the use of topology-optimized splints in treating distal radius fractures, which prompted a study to evaluate their effectiveness compared to traditional casts.
  • A randomized clinical trial involving 110 participants aimed to compare the outcomes of topology-optimized splint immobilization and cast immobilization over a 12-week period, including a 6-week treatment phase.
  • Results showed that at 6 weeks, the splint group had a statistically significant better mean Gartland-Werley wrist score compared to the cast group, but by 12 weeks, no significant differences were noted between the two groups.

Three-dimensional (3D) printed splints must be lightweight and adequately ventilated to maximize the patient's convenience while maintaining requisite strength. The ensuing loss of strength has a substantial impact on the transformation of a solid splint model into a perforated or porous model. Thus, two methods for making perforations-standard approach and topological optimization-are investigated in this study.
