“…One of the "game changers" in the techniques used to perform pelvic osteotomies was the implementation of locking screw systems for traditional pelvic plates. Recent studies have shown a tremendous decrease in screw related complication to 0.5% (34). Locking technology reduces the need for precise plate contouring because the locking screws do not rely on friction between the plate and the underlying bone and this may significantly reduce the incidence of screw loosening.…”

Canine Hip Dysplasia (CHD) is considered to be one of the most common orthopaedic diseases and it consists of coxofemoral joint incongruence leading to femoral head subluxation and osteoarthritic changes. The affected dogs tend to present progressive pain and mobility issues. The widely used CHD managing strategies, among others, include pelvic osteotomy techniques. In recent years, great efforts have been made to improve the surgical procedure and reduce the rate of complications, which seems to be a possibility due to the introduction of constructional changes in modern TPO/DPO plates.

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 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.

Comparison of Rotation Force to Maintain Acetabular Ventroversion after Double Pelvic Osteotomy and 2.5 Pelvic Osteotomy in a Canine Cadaveric Model

Abstract: Dorsal cortex osteotomy of the ischium decreases the acetabular segment rotation force. Decreased force may facilitate acetabular rotation during DPO procedure.
