However, some hospitals lack specialized USO plates, or patients decline them due to high costs. The freehand technique for USO lacks precision; therefore, we utilized 3D-printed guide plates to assist in performing USO and fixation with standard ulnar locking plates.<\/jats:p>\n                  <jats:p>A retrospective case series of 87 patients was conducted using 3D-printed guide plates to achieve precise USO and fixation with standard ulnar locking plates. Primary outcomes included the patient-rated wrist evaluation (PRWE), disabilities of the arm, shoulder, and hand (DASH) questionnaire, and a custom patient satisfaction survey. Secondary outcomes included implant removal due to irritation and other complications.<\/jats:p>\n                  <jats:p>The mean postoperative functional scores were 26 (standard deviation [SD]: 30) for PRWE and 21 (SD: 26) for DASH.
