Thirty‐six dogs undergoing 49 pelvic osteotomies (POs) stabilised either by manually twisted dynamic compression plates (DCPS; n= 29) or canine pelvic osteotomy plates (CPOPS; n = 20) were retrospectively reviewed. Postoperative radiographs were available for all POs and 36 had additional radiographic follow‐up. Pelvic osteotomies with CPOPs were more likely to have three screws placed in the sacrum while DCPs were associated with none, one or two screws in the sacrum. There was no difference in the postoperative sagittal alignment of the acetabular segments for POs with DCPs or CPOPs. Screw loosening was the most common complication (n = 13/36, 36 per cent), usually involving screws in the ilial segment. On follow‐up radiographs, medial displacement of the acetabular segment was most frequently associated with screw loosening and plate bending. Medial displacement of the acetabular segment caused apparent pelvic narrowing on radiographs, more pronounced in dogs with bilateral POs, but clinical problems were not reported.
