“…Pelvic osteotomies aim to increase femoral head‐dorsal acetabular coverage to improve joint congruency in dogs affected by hip dysplasia 3–6 . The acetabular rotation is fixed using a preangled plate 1,3–7 . The double pelvic osteotomy (DPO) may be considered an evolution of the triple pelvic osteotomy (TPO) in which a pubic ostectomy and an ilial osteotomy are performed, leaving the ischium intact 4–7 .…”

“…Double pelvic osteotomy had therefore been exclusively performed in young dogs ranging from 4.5 to 9 months of age 4 . Age is generally used as a selection criterion for pelvic osteotomies for assessing whether the dog already has secondary osteoarthritis 5 . However, we contend that osteoarthritic changes should be assessed regardless of the dog's age.…”

Objective To report the short‐term outcome of double pelvic osteotomy (DPO) in dogs with canine hip dysplasia ≥10 months of age. Study design Case series. Animals or sample population Eleven hips in eight dogs aged between 10 to 28 months. Methods Dogs clinically affected by hip dysplasia with a hip reduction angle <40°, subluxation angle <25°, dorsal acetabular rim angle between 7.5–25°, and minimal osteoarthritic changes were considered as candidates for DPO. The clinical outcome was subjectively assessed using a lameness score and pain scale upon hip extension. Norberg angle, percentage of the area of the femoral head coverage, percentage of linear femoral head coverage, pelvic width dimensions were measured on pre and postoperative radiographs. Results At the 8‐week follow‐up examination, all the dogs had no lameness with no pain upon hip extension. Median Norberg angle increased by 21.8% (p < .01), median percentage of the area of the femoral head coverage increased by 66.7% (p < .01) and percentage of linear femoral head coverage increased by 162.5% (p < .01) 1 year after DPO. No changes to pelvic canal width after DPO were detected. Conclusion Double pelvic osteotomy improved joint congruity and clinical signs in dogs affected by hip dysplasia without osteoarthritis that were ≥10 months of age. Clinical significance (or impact) Double pelvic osteotomy may be a treatment option for dogs with hip dysplasia ≥10 months of age. A large study assessing long‐term outcomes is indicated.

“…It showed that DPO significantly reduced the progression of radiographically confirmed coxofemoral osteoarthritis; however, the radiographic changes were not correlated with the clinical outcome. 31 Plates designed specifically for DPO have been commercially available since 2008 and were developed to reduce the incidence of complications seen when triple pelvic osteotomy plates were used for DPO. The main difference between triple pelvic osteotomy and DPO plates is the pattern of fixation of the cranial and caudal parts of the plate or the number of screws in the caudal part (4 instead of 3).…”

Objective The aim of this clinical retrospective study was to describe the postoperative complications and associated factors of double pelvic osteotomy (DPO) using DPO plates. Materials and Methods Medical records were searched for dogs that underwent unilateral or bilateral DPO using DPO plates from February 2009 to October 2018 and were re-evaluated for a minimum of 1 to 2 months postoperatively. A variety of commercially available, specific DPO plates were used. Complications were determined during the immediate postoperative period and at the time of the clinical and radiographic re-evaluations done 1 and/or 2 months postoperatively. Results A total of 458 DPO (226 right, 232 left) performed in 305 dogs satisfied the inclusion criteria. Double pelvic osteotomy plates from eight different manufacturers were used: Fixin (n = 160), Kyon (n = 154), New Generation Device (n = 63), Hofmann (n = 61), Veterinary Instrumentation (n = 12), DePuy Synthes (n = 4), Porte (n = 3) and Koenigsee (n = 1). Mean age of the dogs was 6.2 months (range: 5–8 months), and the body weight ranged from 10 to 47 kg. Overall, a total of 42 complications occurred in 38 DPO (8.2%). Complications included greenstick fracture of the ischium in 14 DPO (3%), isolated screw loosening in 13 DPO involving 16 of a total of 2,947 screws (0.5%), isolated screw breakage in 4 DPO involving 5 of 2,947 screws (0.1%), incomplete ilium fracture in 3 DPO (0.6%), partial caudal plate avulsion in 3 DPO (0.6%), iatrogenic sciatic neuropraxia in two DPO (0.4%), suspected surgical site infection (SSI) in 1 DPO (0.2%) and persistent pain and lameness caused by the implant in 2 DPO (0.4%). The case of suspected SSI and the two cases of persistent pain were classified as major complications (3 DPO, 0.6%), requiring medical and surgical intervention, respectively, whereas other 39 complications in 35 DPO were classified as minor, not requiring treatment (7.6%). Conclusion Double pelvic osteotomy using DPO plates appears to be a safe surgical option for the treatment of hip dysplasia in growing dogs; no catastrophic complications were reported and the incidence of complications (0.6% major complications and 7.6% minor complications) was low. This study showed that DPO using DPO plates and proper technique was safe in 92% of cases. The only two factors found to be significantly associated with the development of complications after DPO were the laterality (left-sided or right-sided) and body weight.

Objective The aim of this study was to assess the kinetic and radiographic outcome of unilateral double pelvic osteotomy (DPO) using a temporospatial pressure walkway, preoperative and postoperative radiographs. Study Design Retrospective case series of six dogs that underwent unilateral DPO for canine hip dysplasia. The untreated limb was unfit for DPO due to radiographic evidence of osteoarthritis and was therefore managed non-surgically. Preoperative and postoperative radiographs and kinetic data were compared between untreated and DPO-treated hips using a Wilcoxon signed-rank test. Results There was no significant difference in British Veterinary Association Hip Dysplasia Scheme (BVA-HD) scores between untreated and DPO-treated hips preoperatively (p-value = 0.09) and postoperatively (p-value = 0.06). The median postoperative GAIT4 Dog Lameness Score was lower in untreated hips than DPO-treated hips but was not statistically different (p-value = 0.18). Conclusions All dogs in this case series achieved a total pressure index and GAIT4 Dog Lameness Score on the DPO-treated hip comparable to normal limbs. All untreated hips in this series had increased BVA-HD scores at follow-up, whereas all DPO-treated hips had reduced BVA-HD scores. This difference was not significant and warrants further studies. We conclude total pressure index may be preserved in hips treated with unilateral DPO, while the contralateral hip is managed non-surgically.
