Joint Congruence

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.

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.

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.

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.

Objective The purpose of this study was to investigate mobility performance in dogs suffering from hip osteoarthritis secondary to hip dysplasia using kinesiology. Materials and Methods Twenty dogs with a radiographical diagnosis of bilateral hip dysplasia and hip osteoarthritis and 20 healthy dogs were submitted to kinetic and kinematic analysis while climbing upstairs, walking down a slope, sitting down, standing up, and walking. Dogs were also scored by two blind examiners using a visual analog scale (VAS). Results Dysplastic dogs had lower peak vertical force (4% of body weight on average), increased symmetry index (12.6% difference on average) and reduced maximum hip joint extension angle and range of motion (ROM) in all tests. Mean hip joint range of motion difference was 11, 20, 25.4 and 25.2 degrees (walking, climbing upstairs, walking down a slope, sitting down and standing up exercise respectively). The VAS scores varied widely between examiners; still, healthy and dysplastic dog mobility differed across all physical test tasks. Conclusion and Clinical Relevance Gait changes were observed in all physical tasks performed by dysplastic dogs with hip osteoarthritis, particularly in those requiring higher levels of effort. Comprehensive, quantitative assessment of dogs suffering from hip osteoarthritis across a range of physical activities is recommended.

SummaryThe aim of this study was to evaluate the feasibility of the double pelvic osteotomy (DPO) (osteotomy of the ilium and pubis) to treat clinical cases of hip dyplasia in young dogs instead of performing a triple pelvic osteotomy (TPO) (osteotomy of the ilium, pubis, and ischium). Candidates for DPO were 4.5- to nine-month-old dogs with coxofemoral joint subluxation and laxity, indicative of susceptibility to future development of severe hip dysplasia. The angle of reduction (AR) and angle of subluxation (AS) with Ortolani's sign, Norberg angle (NA), percentage of femoral head (PC) covered by the acetabulum, and the pelvic diameters and their relationships were measured clinically and radiographically before and after surgery. The surgical technique was similar to the TPO technique, but excluded ischiatic osteotomy. A DPO was carried out in 53 joints of 34 dogs AR and AS values immediately postoperatively and at the oneand two-month follow-up examinations were significantly lower than the preoperative values (p <0.01). The complications en-countered were mainly represented by implant failure (3.5%), partial plate pull-out (9.4%), and incomplete fracture of the ischial table (7.5%). Changes in PC and NA values obtained immediately after surgery and at the first and second follow-up examinations were significantly greater (p <0.01 both) than values obtained before surgery. Sufficient acetabular ventroversion was achieved to counteract joint subluxation and the modifications of AR and AS. The NA and PC direct postoperative values reflected a significant improvement in the dorsal acetabular coverage. Clinical relevance: Restoration of normal joint congruity (PC from 50 to 72%) and maintenance of the pelvic geometry without pelvic narrowing were the most intriguing features of DPO. The complications observed were greatly reduced when using dedicated DPO plates. Based on our experience, the morbidity after unilateral and bilateral DPO was lower than after TPO because elimination of the ischiatic osteotomy allowed for increased stability of the pelvis. The surgical technique of DPO was a little more demanding than TPO because of the difficulty in handling and rotating the acetabular iliac segment, but this difficulty was offset by elimination of ischial osteotomy.

Abstract Introduction: Degenerative changes are one of the most often appearing causes of the affliction located in the locomotor system where the hip joint is one of the most common locations. One can observe such symptoms as: limited movement, pain and muscle weakness. One of the therapy methods that are aimed at improving movement and reducing the affliction are techniques used in manual therapy (e.g. mobilization). The Kaltenborn-Evjenth method has been applied in physiotherapy practice for many years. The aim of the research was to assess the effectiveness of mobilization techniques directed at the synovial capsule (manual therapy) while treating degenerative changes of the hip joint. In literature no report that refers precisely to the subject mentioned above was found. Being assessed was the influence of therapy on the range of the joints movement and the level of pain. Material and methods: A group of 20 people with degenerative changes of the hip joint were examined (16 women and 4 men, average age - 65 years). Measurements of the hip joint range movement were performed (the flexion, extension, abduction, adduction and rotation) and the assessment of the level of felt pain (VAS) before and after the therapy. The therapy using mobilization techniques taken from the Kaltenborn-Evjenth concept was conducted in a series of 6 therapy sessions lasting 2 weeks. Results: In all comparisons of the range of motion in the hip joint an increasing was stated (p < 0.001) after the therapy. In the case of pain level a decreasing was observed (p < 0.001) after the therapy. Conclusions: It seems right to use manual therapy techniques in physiotherapy proceedings in the course of the degenerative disease of the hip joint, aimed on for e.g. the synovial capsule.

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.
