A 36-year-old Thai woman fell from her motorcycle and injured her right wrist. Radiographs showed a comminuted intra-articular fracture of the base of the first metacarpal bone, known as a Rolando fracture. The fracture was treated with application of a thumb spica cast initially, followed by open reduction internal fixation using a miniplate to surgically repair the fracture fragments. Rolando fractures involve comminution of the base of the first metacarpal and typically result in worse prognosis and higher risk of post-traumatic osteoarthritis compared to other thumb metacarpal fractures like Bennett fractures.
