Which splint is commonly used to immobilize a Rolondos fracture?

• A. Thumb Spica Splint
• B. Sugar Tong Splint
• C. Short Arm Cast
• D. Ulnar Gutter Splint

Answer: (A)

Immobilizing the base of the first metacarpal requires locking the thumb and its carpometacarpal joint to prevent movement that could disrupt the fracture surface. A Rolando fracture is a comminuted intra-articular fracture at this location, so providing rigid stabilization across the thumb’s base is essential. The thumb spica splint does just that: it encases the thumb and immobilizes the CMC joint, protecting the fracture during healing and reducing pain. Other splints focus on different areas: a sugar tong splint and a short arm cast primarily immobilize the wrist and forearm, not the base of the thumb; an ulnar gutter splint targets the fourth and fifth digits. These don’t adequately stabilize the first metacarpal base, making them less suitable for a Rolando fracture. If the fracture is displaced or unstable, surgical management may be considered, but initial care is typically immobilization with a thumb spica splint.
