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.

Abstract Background: Residual hip dysplasia is one of the factors contributing to early hip joint osteoarthritis. The main problems caused by residual dysplasia are pain and instability of the hip joint caused by the lack of sufficient bony covering of the femoral head. The aim of this work was to radiologically assess the configuration change of a dysplastic hip joint after surgical treatment using the Bernese periacetabular osteotomy procedure.Methods: We assessed the radiological parameters of patients with hip dysplasia treated by Bernense periacetabular osteotomy by performing a digital antero-posterior pelvis X-ray: central edge angle and femoral head coverage, medialization, distalization and ilio-ischial angle parameters. For normally distributed parameters, we used Student’s t-test; for parameters without a normal distribution, we used the Wilcoxon signed-rank test. Correlations were assessed according to a normal distribution using the Pearson and Spearman method.Results: For all parameters, we observed statistically significant differences in the measurements of dysplastic hip joints before and after the surgery. We also observed a statistically significant difference between the structure of dysplastic hip joints prior to the surgery and healthy hip joints from the control group based on all radiological parameters. The resulting medialization was 2.68 mm, distalization was 3.65 mm, and the ilio-ischial angle was changed by 2.62°. There was also an improvement in the femoral head bony covering: CEA by 17.61° and FHC by 16.46%.Conclusions: Based on all the radiological parameters, we presented the difference between healthy and dysplastic hip joints. Learning the parameter values that are used to describe dysplastic hip joints will allow us to improve the imaging of the condition and will also allow for better planning and proper qualification of patients for surgical treatment of hip joint dysplasia.Trial registration: Consent of the bioethics commission Medical Centre of Postgraduate Education 83/PB/2015 18.11.2015 Warsaw

Background: Hip dysplasia (HD) is the most common non-traumatic orthopedic disease in large breed dogs. Treatment is chosen according to the severity of the condition, the age of the dog and the involvement of osteoarthritis (OA). For puppies up to 20-weeks-old, surgical treatment by the juvenile pubic symphysiodesis (JPS) technique can be performed. This procedure promotes the ventrolateral rotation of the acetabulum over the femoral head, which improves hip joint congruence and stability. The objective of this study is to report the case of a young dog with HD treated with JPS and pectineus myectomy. Clinical and radiographic outcomes were assessed for up to one year after surgery.Case: A 17-week-old Saint Bernard puppy was attended at the University Veterinary Hospital showing abnormal weight bearing and lameness in pelvic limbs, without history of previous trauma. On orthopedic examination, there was a marked hypotrophy of the pelvic limb muscles, severe pain and laxity in the hip joints, and positive feature in the Ortolani test. The hip joint subluxation angle (SA) and reduction angle (RA) were measured. A radiographic study was carried out to evaluate the hip joints and measure the Norberg angle (NA), distraction index (DI), acetabular angle (AA) and dorsal acetabular rim angle (DARA). The 20-week-old dog underwent surgical treatment by JPS technique. A ventral surgical approach to the pubis was performed and the pubic symphysis was cauterized with electrocautery. Partial pectineus myectomy technique was also performed. Drug therapy and restriction of physical activities were indicated in the early postoperative. The dog was evaluated by clinical and radiographic examinations at 4 months and 1 year after the surgical procedure. In the reassessment after 4 months of surgical treatment, the patient showed improvement in clinical signs, with mild lameness and absence of painful sensitivity in the movement of the hip joints. Radiographically, hip joint incongruity was observed, but with progressive improvement in the values of the measured variables. In the clinical examination 1 year after the procedure, the dog showed satisfactory weight bearing with slight lameness in pelvic limbs in the running gait. There was improvement in the thigh muscles and no painful signs were observed in the hip joints, but a positive result was detected in the Ortolani test. In the radiographic examination, bilateral articular incongruity was still observed, however, there was a mild improvement in the coverage of the acetabulum over the femoral head. The measured angles and indices showed favorable results regarding the recovery of hip joint stability and proper development.Discussion: Studies evaluating the JPS technique for the treatment of HD have shown to be a relatively simple and effective procedure, which allows altering the acetabular coverage, reducing the development of HD and the progression of OA. The need for an early diagnosis of this condition is essential, so that the JPS technique can be used in young dogs and offer effective results. In the present report, in the late postoperative period, the dog showed improvement in clinical signs, with favorable weight bearing and ambulation in pelvic limbs, recovery of limb muscles, absence of pain in the hip joints and decrease in RA and SA. Radiographically, the reduction in joint subluxation, improvement in acetabular coverage over femoral heads, increase in NA and AA, reduction in DI and DARA are evidence of the favorable outcome of ventrolateral rotation of the acetabulum after surgical treatment. The surgical technique used was effective, which enabled the dog to recover the functional use of the pelvic limbs and improve the quality of life.Keywords: hip dysplasia, juvenile pubic symphysiodesis, hip joint, osteoarthritis, dog.Título: Sinfisiodese púbica juvenil associada à miectomia do pectíneopara tratamento de displasia coxofemoral em cãoDescritores: displasia coxofemoral, sinfisiodese púbica juvenil, coxofemoral, osteoartrite.

In this study, triple pelvic osteotomy (TPO) was carried out in a total of 22 dysplastic dogs, of which 9 were treated bilaterally and 13 unilaterally, and the position of the acetabulum was changed in a total of 31 hip joints using a special plate. It was established that, of the treated hip joints, 16 had severe, 12 medium and 3 mild dysplasia, the Norberg angle was between 70&ndash;92&deg; and that the covering rate of the acetabulum over the femoral head changed between 5&ndash;42&deg;. In the radiographs taken immediately after the operation, the covering rate of the acetabulum over the femoral head was determined to be very good in 25 hip joints (75% and over) and good in 6 joints (60&ndash;75%). In 5 cases, some of the screws holding the plate in place were seen to loosen in radiographs. However, this did not have any effect on the angle given to the acetabulum. In radiographs obtained 6&ndash;48 months later, degenerative joint disease was not encountered in 29 cases, with the exception of 2 cases. It was concluded that hip dysplasia, which is a hereditary disease, can be treated reasonably successfully in young dogs with TPO carried out before degenerative changes begin to occur in the joint.

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.

Destructive Arthropathy

Purpose. To assess the vascularity of the femoral head and determine how it is related to the destruction of the arthritic hip joint. The process of destructive arthropathy in arthritic hip joints is variable. Some patients with osteoarthritis of the hip have rapidly progressive destructive changes resulting in the disappearance of the femoral head. Method. Six femoral heads from patients diagnosed with rapidly destructive arthropathy and 6 femoral heads from patients with secondary osteoarthritis caused by acetabular dysplasia were analysed to reveal the association between blood capillaries and osteoclasts. The von Willebrand Factor immunostaining and counterstaining with Mayer's haematoxylin were used to label the microvessels and osteoclasts in formalin-fixed, paraffin-embedded specimens of femoral heads. The numbers of immunostained microvessels and osteoclasts in selected regions were counted. Result. The microvascular density of the bone surfaces of rapidly progressive arthritic hips was hypervascular. Osteoclasts were also found in increased numbers on the bone surfaces of rapidly progressive arthritic hips. The higher microvascular density coincided with extensive bone destruction and with the increased osteoclast count. Conclusion. These findings suggested that hypervascularity of the granulation in the femoral head may be associated with bone and joint destruction.

Ventrodorsal pelvic radiographs were made of 32 adult dogs under general anaesthesia. The hip joints were evaluated according to the severity of osteoarthritic changes graded as 0, 1, 2 or 3. The dogs were euthanased, the hip joints opened and the ligamentum capitis femoris dissected out in toto. The volume of each ligament was determined using a water displacement technique and the mean volume compared to the four radiographic grades of osteoarthritis. There was an inverse correlation (r = -0.75) between the mean volume of the ligamentum capitis femoris and the increasing severity of osteoarthritis as assessed by radiography. The results confirmed the crucial role of radiography in the clinical evaluation of hip dysplasia and osteoarthritis in the adult dog. Assessment of the volume of the ligamentum capitis femoris revealed that it is an important tool for research in canine hip dysplasia and osteoarthritis.

The increase in the number of patients with hip pathologies among children of different ages makes the diagnosis and treatment of these diseases one of the most actually existing problems in modern orthopedics. The aim of the work was to determine the features of the lipid peroxidation system - antioxidant protection and hemogram indices in children with various forms of hip joint pathology. The results of a preoperative examination of 47 patients aged 6-15 years (average age 10.3 years) who were treated at the clinic “FSBI NICC“ TO ”named after academician G. A. Ilizarova, Ministry of Health of the Russian Federation. There were 25 boys and 20 girls. Given nosology, patients were divided into five groups. The diagnosis was established on the basis of a clinical and radiological examination. Group I consisted of 8 male patients with stage II Perthes disease (mean age 8.75 + 1.63). Group II includes 16 patients (8 boys, 7 girls) with stage III Perthes disease. (average age 11.80 + 0.89). Group III included 12 patients (6 boys, 6 girls) with aseptic necrosis of the femoral head (average age 14.7 + 2.35). Group IV consisted of 4 patients (1 boy, 3 girls) with epiphyseal dysplasia. (average age 10.25 + 1.36). Group V includes 7 patients with hip dysplasia complicated by aseptic necrosis of the femoral head (mean age 8.33 + 2.11). The norm is the data that was obtained after examining 10 healthy male adolescents (age 13-14) and 5 female adolescents (age 8-14 years). Changes in lipid peroxidation rates and antioxidant activity are unidirectional in different forms of pathology of the hip joints in children, and the content of peroxidation products reliably correlates with hemogram values in stage II osteochondropathy and complicated hip dysplasia. In the complex of diagnostic measures for children with dystrophic lesions of the hip joint, to clarify the nature and stage of the pathological process, as additional criteria, hemogram indicators and lipid peroxidation systems - antioxidant protection can be used.

SummaryThe prevalence of rotation of the pelvis along its length axis was noted, as was the number of rotations towards the right or left hand side of the dog, on 7,012 conventional hip extended radiographs, which were sent for official screening. 29.8% of the radiographs showed a rotation the pelvis. The rotation was statistically more frequent towards the left hand side of the dog. The number of rejected radiographs for too important pelvis rotation was only 5.2%. The consequences of the pelvis rotation on the Norberg-Olsson angle, on the dorsal femoral head coverage, and in the aspect of cranial acetabular edge have to be taken into account when scoring the dog for hip dysplasia.

Simultaneous bilateral femoral head and neck ostectomy (FHO) was performed on 15 dogs for severe bilateral hip dysplasia. A follow-up survey was performed 6 to 48 months after surgery to assess the postoperative recovery and activity levels of the operated dogs. All dogs had normal activity levels and were pain free according to their owners. Owner satisfaction regarding the outcome of the surgery was high. Simultaneous bilateral FHO was a viable surgical option for the treatment of painful bilateral hip disease in dogs, especially when other surgical options were not indicated or were cost prohibitive.

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.
