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.

Chiari Pelvic Osteotomy

Introduction: The Chiari pelvic osteotomy (CPO) has been recommended as a salvage procedure to improve head coverage in case of hip joint incongruence in paediatric hip disease. In this study, we aimed to assess the long-term results of CPO for severe Legg-Calvé-Perthes disease (LCPD). Methods: A total of 39 patients who underwent a CPO at our department between 1995 and 2010 were prospectively followed both radiologically (Stulberg classification) and clinically (Harris Hip Score [HHS], conversion into total hip arthroplasty). In this study, we retrospectively reviewed the cases of 12 hips (12 patients, 3 girls, 8 left hips) treated by CPO for severe LCPD (Catterall grade 3 or 4) with hip joint incongruence. Mean follow-up was 14.0 (range 7.6–21.3) years. Results: Mean age at surgery was 10.2 (range 8.2–17.8) years. Additional femoral osteotomy was performed in 8 patients. A good radiological result (Stulberg I or II) was achieved in 2 patients, a fair result (Stulberg III) in 4 patients, and a poor outcome (Stulberg IV or V) in 6 patients. Mean postoperative HHS averaged 93 (range 65–100) points. An excellent functional outcome (HHS 90–100 points) was achieved in 9 patients. No patient underwent total hip arthroplasty during follow-up. Postoperative limb-length discrepancy was found in 3 patients. Conclusions: CPO for severe LCPD with hip joint incongruence resulted in good long-term clinical outcome in about ⅔ of our patients after a mean of 14 years. Our results suggest that CPO can still be considered as a salvage joint-conserving procedure in this selected group of younger patients.

SummaryThe efficiency of conservative treatment, excision arthroplasty of the femoral head and neck and triple pelvic osteotomy for the treatment of hip dysplasia in the immature dog were compared using locomotor, physical and radiographic examinations and owner’s evaluation. Cases selected for this study were dogs diagnosed with bilateral hip dysplasia, initially admitted with clinical signs (lameness, pain), immature at the beginning of the treatment (less than 12 months of age), with both hips subjected to the same treatment (conservative treatment, excision arthroplasty of the femoral head and neck or triple pelvic osteotomy). These dogs never showed any musculoskeletal problems other than hip dysplasia and the surgical treatment had been completed at least 20 months prior to re-evaluation time. Fourteen hips were re-evaluated in the conservative group, 16 in the triple pelvic osteotomy group and ten in the excision arthroplasty group. Locomotor, physical and owner’s evaluations demonstrated the superiority of the triple pelvic osteotomy. These evaluations also showed that excision arthroplasty was more efficient than conservative treatment. Radiographic examination demonstrated the obvious superiority of the triple pelvic osteotomy over conservative treatment.Locomotor, physical and owner’s evaluations demonstrated the superiority of the triple pelvic osteotomy over conservative treatment and excision arthroplasty for the treatment of hip dysplasia in the immature dog.

Chiari Pelvic Osteotomy

Background: The modern indications for Chiari pelvic osteotomy (CPO) have narrowed and the number of such operations performed has diminished markedly. So far published long-term experience with CPO indicate the fact that in selected patients satisfactory functional results can be achieved. The aim of this study was to investigate the parameters which influence CPO survival and its conversion into total hip arthroplasty (THA). Methods: This is a single-centre retrospective case-series study. In the period from 1976 to 2012, it included 172 CPO in 158 patients. Of those, in 43 patients (48 hips) the follow-up was discontinued, leaving 115 patients (124 hips) for final analyses. The median age at the time of the surgery was 34 years, and the mean duration of the follow-up was 19 years. Results: In 115 patients (124 CPO) included in the study, a total of 51 THA was performed in 49 patients. The median period between CPO and THA was 14 years. Conclusion: Supporting our results, we suggest that CPO should still be indicated in a selected group of younger patients even with advanced stage of hip osteoarthritis who prefer a joint-conserving procedure and consent to a predicted less optimal outcome.

Chiari Pelvic Osteotomy

Chiari pelvic osteotomy is a surgical procedure having been performed for almost sixty years in patients with the insuffcient coverage of the femoral head. It is most frequently used in young patients with dysplastic acetabular sockets as a part of developmental hip dysplasia. Even though performance of the Chiari osteotomy is associated with positive therapeutical results, above all, its main goal is to delay inevitable degenerative changes. Original surgical technique has been modified and improved over time. Nevertheless, the basic idea has remained unchanged - increasing of the femoral head coverage by medial displacement of the distal part of the pelvis along with capsular interpositioning. Given the complexity of operation, the complication percentage is rather low. Chiari pelvic osteotomy has lost its actuality and importance during this past six decades. The role of Chiari pelvic osteotomy has been considerably taken over by other more efficient and more lasting surgical procedures. Nonetheless, Chiari pelvic osteotomy is still present in modern orthopedic practice, above all as ?salvage? osteotomy.

SummaryTriple pelvic osteotomy (TPO) was used in the treatment for traumatic coxofemoral luxations in four adult, large breed dogs with hip dysplasia. Initial closed reductions failed in three and one dog had an initial closed reduction and subsequent open reduction of the coxofemoral luxation that failed. Hip dysplasia was thought to be a prominent factor contributing to the reluxation. TPO successfully maintained reduction of the coxofemoral luxation in all of the dogs. An increase in dorsal acetabular coverage of the femoral head following TPO was demonstrated by an increased Norberg angle. The improved congruency was thought to maintain reduction of the femoral head in the acetabulum and decrease stresses on the joint capsule, allowing healing to occur. Long-term (median: 343, mean ± SD: 406 ± 226 days follow-up) function of the affected limb was comparable to the contralateral limb. Three of the four dogs did not have radiographic progression of coxofemoral degenerative joint disease of the affected joint and differences in the progression of degenerative joint disease were not evident between the affected and the contralateral coxofemoral joint. A decrease in abduction and external rotation and an increase in internal rotation following TPO was noted in the affected coxofemoral joint. Our results establish the utility of this procedure in dysplastic dogs with traumatic coxofemoral luxations.Triple pelvic osteotomy used in the treatment for traumatic coxofemoral luxation in four adult, large breed dogs with hip dysplasia successfully maintained reduction and resulted in satisfactory limb function in all patients.
