Abstract
Corrective osteotomy for a malunited distal radial fracture (DRF) can be challenging. Three-dimensional printing techniques can be used to produce patient specific implants (PSIs). Theoretically, this technique improves accuracy of reconstruction and therefore patient-related outcomes. The aim of this retrospective cohort study was to compare pre- and postoperative patient-rated functional and radiological outcomes following corrective osteotomy of 47 malunited DRFs with PSIs. The primary outcome was the difference in Patient-Rated Wrist Hand Evaluation score (PRWHE). The median PRWHE improved from 68 (IQR: 60 to 77) to 17 (IQR: 7 to 30) after a median follow-up of 15 months in 32 patients. The mean preoperative dorsal tilt of -15° (SD: -8), improved to 7° (SD: 7) palmar tilt postoperatively in 46 patients. Preoperatively, 28 patients exhibited radiocarpal malalignment, which decreased to five postoperatively. Corrective osteotomy of a malunited DRF with a PSI can lead to improved PRWHE, range of motion and radiological outcomes.Level of evidence: IV.
