SummaryTreatment of canine hip dysplasia (CHD) via triple pelvic osteotomy (TPO) is widely accepted as the treatment that best preserves the existing hip joint. TPO, however, has several important disadvantages. In an effort to avoid some of the difficulties associated with TPO an alternative method of creating acetabular ventroversion (AW) was sought. The purpose of this study was to explore the effects of placement of a wedge in the sacroiliac (SI) joint on A W and to compare this to the effect of TPO on A W . On one hemipelvis a 30° pelvic osteotomy plate was used for TPO. The contralateral hemipelvis had a 28° SI wedge inserted into the SI joint. Pre- and postsurgical radiographs of each pelvis were taken and the angular measurements were recorded. On average, the 28° SI wedge resulted in 20.9° of A W, the 30° canine pelvic osteotomy plate resulted in 24.9° A W . Significant differences were not found (p >0.05) between the two techniques. Sacroiliac wedge rotation effectively creates A W and has several theoretical advantages when compared to TPO. The in vivo effects of sacroiliac wedge rotation should be studied in order to evaluate the clinical effect of the technique.Sacroiliac wedge rotation was tested as an alternative method to increase the angle of acetabular ventroversion. This technique effectively rotated the acetabulum and has several theoretical advantages when compared to triple pelvic osteotomy.

SummaryTriple pelvic osteotomy (TPO), as a treatment for canine hip dysplasia, was evaluated radiographically in 38 cases. Several parameters on radio-graphs of the pelvis, taken pre- and postoperatively, as well as six weeks and three months after the operation, were measured and compared. The results were also compared between iliac osteotomy fixation with the canine pelvic osteotomy plate (CPOP, n = 16) and the twisted dynamic compression plate (DCP, n = 22). Acetabular support (from 0.21 to 0.89), Norberg angle (from 77.6° to 111.8°) and hip joint congruence improved significantly after TPO. Dorsal pelvic width did not change, whereas, due to rotation, ventral pelvic width decreased to 80% of its pre-operative value. Osteophyte formation was judged to be moderate three months after the operation. Comparison of the two plating methods showed significant postoperative advantages for the CPO P group in terms of a higher Norberg angle and a better congruence. There was some loosening of 33% of the screws in both groups, but this did not interfere with the aim of the TP O procedure.The effect of triple pelvic osteotomy, as a treatment for canine hip dysplasia, was investigated retrospectively by means of radiographs. Acetabular support, the Norberg angle, and hip joint congruence improved significantly after the operation. Iliac osteotomy fixation, with the canine pelvic osteotomy plate, displayed advantages over the twisted dynamic compression plate. Screw loosening occurred frequently but without any major consequences.

Mean Time

Triple pelvic osteotomy (TPO) is a prophylactic surgical procedure performed on dogs with canine hip dysplasia. The procedure is indicated in skeletally immature dogs without secondary osteoarthritis (OA). It has been suggested that 60° of rotation is excessive and is associated with poor outcome. The objective of the study was to assess the medium term outcome in dogs having undergone triple pelvic osteotomy (TPO) using 60° dedicated plates. Nine TPOs were performed in seven dogs with hip dysplasia. Eight of nine hips had 72–100% osseous union at the time of revisit. The mean time to final radiographic recheck was 200 days (range, 185–229 days). The mean time to follow-up was 11.5 months (range 11–12 months). All 7 dogs had regained full function and did not require supplemental analgesia. Pelvic canal narrowing was noted in the two dogs with bilateral surgeries, but no clinical consequences were noted according to owner's statement.If more than 40 degrees reduction angles at Ortolani test, 60° of rotation of the acetabulum can be used successfully in dogs with hip dysplasia. At the time of mid-term follow-up, all dogs in this case series had full function.

SummaryFifteen dogs undergoing triple pelvic osteotomy (TPO) for bilateral hip dysplasia were evaluated prospectively. Ten dogs were treated bilaterally, five dogs were treated unilaterally. Hip joint palpation, radiography and goniometry were performed before surgery and at 5, 10, 15, and 28 weeks after surgery.Joint congruence was significantly improved palpably and radiographically in treated hips while congruence deteriorated in untreated hips. Improvement in congruence was minimal after the five week evaluation. Goniometric measurements were variable but range of motion was generally not decreased after TPO.

Background. Transposition of the acetabulum after pelvic osteotomy is the most effective surgical method to treat dysplastic hip joint disorders in patients of different ages. According to Salter, iliac osteotomy of the pelvis is the main surgical method used to correct dysplastic acetabulum in 7- and 8-year-old children. In older patients, the pubic symphysis and pelvic ligaments become more rigid, which significantly limits the degree of rotation of the acetabulum. In these cases, a triple pelvic osteotomy is performed to enhance the mobility of the acetabular fragment. This pubic bone osteotomy is performed near the femoral neurovascular bundle, which may be damaged during the procedure.Aim. To describe a technique for transposition of the acetabulum after iliac and ischial osteotomy of the pelvis, which was developed to reduce trauma, prevent vascular complications, and increase postoperative stability of the pelvic ring.Materials and methods. A method developed by the authors for transposition of the acetabulum after iliac and sciatic pelvic osteotomy is described in detail. The surgical method was performed 99 times on 89 children with dysplastic hip joint disorders, and the results are presented.Conclusion. Transposition of the acetabulum after iliac and ischial pelvic osteotomy is an effective treatment for dysplastic instability of the acetabulum in children aged 9–16 years. The procedure is indicated when it is necessary to rotate the acetabular fragment by more than 25°, and there is no need for hip medialization.

Summary Objectives: This study examines the relationship between the morphology of the lumbosacral transitional vertebra (LTV) and asymmetrical development of the hip joints in dogs. Methods: A total of 4000 dogs which had been consecutively scored for canine hip dysplasia were checked for the presence of a LTV. A LTV was noted in 138 dogs and classified depending on the morphology of the transverse processes and the degree of contact with the ilium. Results: In dogs with an asymmetrical LTV, the hip joint was significantly more predis-posed to subluxation and malformation on the side of the intermediate or sacral-like transverse process (p <0.01), on the side of the elevated pelvis (p <0.01), or when an asymmetrical LTV resulted in pelvic rotation on its long axis (p <0.01), whereas hip joint conformation was less affected on the side featuring a free transverse process (p <0.01). Clinical significance: The results support our hypothesis that an asymmetrical LTV favours pelvic rotation over its long axis, resulting in inadequate femoral head coverage by the acetabulum on one side. Inadequate coverage of the femoral head favours subluxation, malformation of the hip joint, and secondary osteoarthritis. Asymmetrical hip conformation may therefore be the sequela of a LTV and mask or aggravate genetically induced canine hip dysplasia.
