Case Series Study

SummaryA retrospective case series study was done to determine the long-term outcome of operations upon dogs treated for canine hip dysplasia by means of a triple pelvic osteotomy (TPO). Twentyfour dogs with bilateral hip dysplasia, that received a unilateral TPO between January 1988 and June 1995, were re-examined at the Ontario Veterinary College. The assessment included physical, orthopedic and lameness examinations, standard blood work, pelvic radiographs and force plate gait analysis. They were compared to bilaterally dysplastic dogs that had not been treated, and also to normal dogs. Force plate data analysis demonstrated a significant increase in peak vertical force (PVF) and mean vertical force over stance (MVF) in the limb that underwent surgical correction by means of a TPO, when compared to the unoperated hip. It was determined that performing a unilateral TPO on a young dysplastic dog resulted in greater forces and weight bearing being projected through the TPO corrected limb when compared to the unoperated limb.Dogs with bilateral hip dysplasia treated with a unilateral triple pelvic osteotomy (TPO) were assessed by force plate gait analysis, radiographs and orthopedic examination. There was a significant increase in hip Norberg angles over time, although degenerative changes did progress. Limbs that had been operated upon had significantly greater peak and mean ground reaction forces than limbs that had not received an operation.

A Prospective Study

SummaryA few investigations in the 1960’s were performed to document the effect of exogenous oestrogens on development of hip dysplasia. These projects concluded that oestrogen administration caused a significant increase in hip dysplasia. Additionally, the Orthopaedic Foundation for Animals (OFA) has recommended that bitches should not have hip evaluation for certification during oestrus, due to the possibility of increased coxofemoral joint laxity. The purpose of this project was to determine if physiological fluctuations of oestrogen and progesterone throughout the oestrus cycle significantly affected coxofemoral joint laxity. Nine bitches were evaluated through a single oestrus cycle. Although significant fluctuations of oestrogen and progesterone occurred throughout the phases of the oestrus cycle, neither statistically nor clinically significant changes in coxofemoral joint laxity were documented.A prospective study documented the effect of fluctuations of hormone levels throughout the oestrus cycle on coxofemoral joint laxity in nine dogs. Although oestrogen and progesterone levels changed significantly throughout the oestrus cycle, neither statistically nor clinically significant changes in hip laxity were observed.

Canine Hip Dysplasia

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.
