SummaryCemented total hip replacement (cTHR) is commonly performed to treat intractable coxofemoral pain in dogs. While owners generally perceive a good outcome after the procedure, the longevity of the implant may be limited by complications such as infection and aseptic loosening. The objective of this retrospective study was to identify the prevalence of complications and radiographic changes following cTHR, and to identify factors that may predispose to a need for revision surgery. Medical records and radiographs from 97 dogs that underwent cTHR were evaluated for signalment, preoperative degree of osteoarthritis, technical errors, intra-operative culture results, and the post-operative radiographic appearance of the implant. The complications occurring in the intra-operative and short-term (<eight week) periods, and the radiographic appearance of the implant in the long-term (>eight week) time period were recorded. Mean (±SD) follow-up time was 1.1 ± 1.6 years (range: 0–7.7 years). Seven dogs had a short-term complication and a revision surgery was performed in eleven dogs. Osseous or cement changes were radiographically detectable in the majority of cTHR. Eccentric positioning of the femoral stem and the presence of radiolucent lines at the femoral cement-bone interface were positively associated with the occurrence of revision surgery. The clinical significance of the periprosthetic radiographic changes is unclear and further investigation is warranted.

Abstract Background When approaching a joint replacement procedure, pre-surgical planning is essential to predict an accurate estimation of implant size and position. There are currently two methods to achieve it, analog and digital. The present study aims to demonstrate how the hybrid technique is accurate and precise for pre-surgical planning in a non-cemented total hip replacement. Methods Concordance-type study is used against a gold standard, as well as inter- and intra-observer consistency evaluation of two orthopedic surgeons and two orthopedic surgery residents. Accuracy was calculated with the intra-class correlation coefficient (ICC). Afterwards, the same calculation was done considering a margin of error with one size more and one less. Results Thirty-eight patients were included in the study: 19 women and 19 men. Twenty-two prostheses (57.89%) were right-sided and 16 were left (42.11%). Twelve prostheses (31.57%) were Stryker and 26 Johnson & Johnson (68.43%). Acetabular cup correlation compared with the gold standard was moderate: ICC reported 0.45 (95% CI, 0.15–0.76). When adjusted by ± 1 size, ICC was 0.48 (95% CI, 0.18–0.79). On the other hand, results from the femoral stem reported ICC 0.85 (95% CI, 0.07–0.98). When adjusted by ± 1 size, ICC was 0.86 (95% CI, 0.06–0.99). Conclusions Hybrid templating is a reliable substitute for analog or digital planning. It is quick, inexpensive, accurate, and better results are observed in the femoral component regardless the level of expertise of the evaluator. Level of evidence Grade IV

Stem Failure

Introduction. Incidence of Exeter stem fracture is extremely uncommon. Pubic rami insufficiency fractures following arthroplasty are also rare. To our knowledge no cases of spontaneous stem failure with previous insufficiency fractures have yet been reported.Case Presentation. This report describes a case of spontaneous fracture through a cemented Exeter stem in a 66-year-old patient who had previously undergone a hybrid total hip replacement and was found to have bifocal pubic rami insufficiency fractures. The patient presented 18-year postprimary surgery with spontaneous fracture of the middle third of the cemented femoral stem and adjacent proximal femur.Conclusion. This report demonstrates a unique case of Exeter stem fracture with previous pelvic insufficiency fractures. The case adds to the rare occurrences of Exeter stem failure in the literature and highlights the risk of potential insufficiency fractures in patients undergoing total hip replacement.

Cementless Total Hip Replacement

SummaryA two-year-old, 44 kg dog with a right Helica cementless total hip replacement (THR) was radiographically diagnosed with implant loosening eight months after the index total hip replacement procedure. Subsequent synoviocentesis and synovial fluid culture revealed a methicillin-resistant coagulase-negative Staphylococcus spp infection of the right THR. A one-stage revision using a hybrid BFX cementless acetabular cup and CFX cemented femoral stem was performed. Vancomycin and micro-silver antimicrobial powder impregnated cement were used in the revision. At re-evaluation 27 months following the revision procedure, the patient did not exhibit any signs of lameness. Radiographic images confirmed stable implants, with bone ingrowth into the cup and no signs of implant loosening. Our report demonstrates the success of a one-stage THR revision when faced with a multi-drug resistant periprosthetic infection, when combined with the use of micro-silver antimicrobial powder and culture-based antibiotic impregnated cement therapy.

Implant Alignment

Background: Optimal implant alignment is important for total hip replacement (THR) longevity. Femoral stem anteversion is influenced by the native femoral anteversion. Knowing a patient’s femoral morphology is therefore important when planning optimal THR alignment. We investigated variation in femoral anteversion across a patient population requiring THR. Methods: Preoperatively, native femoral neck anteversion was measured from 3-dimensional CT reconstructions in 1215 patients. Results: The median femoral anteversion was 14.4° (−27.1–54.5°, IQR 7.4–20.9°). There were significant gender differences (males 12.7°, females 16.0°; p < 0.0001). Femoral anteversion in males decreased significantly with increasing age. 14% of patients had extreme anteversion (<0° or >30°). Conclusions: This is the largest series investigating native femoral anteversion in a THR population. Patient variation was large and was similar to published findings of a non-THR population. Gender and age-related differences were observed. Native femoral anteversion is patient-specific and should be considered when planning THR.

Abstract Objective The aim of this study was to assess the short-term clinical outcome in dogs following a hip hemi-arthroplasty for the treatment of primary pathological disorders of the hip and as a salvage procedure following failure of the cup component of a total hip replacement. Materials and Methods Medical records of dogs that had a unilateral hip hemi-arthroplasty performed between 2015 and 2020 were reviewed. Data collected included follow-up orthopaedic examinations performed at 0, 2, 8 and 52 weeks postoperatively, pelvic radiography at 0, 8 and 52 weeks postoperatively and an owner questionnaire (Helsinki chronic pain index [HCPI]). Results Eleven unilateral hip hemi-arthroplasty procedures were identified. The median age at time of surgery was 3.6 years (8 months–10 years) and the median follow-up time was 13 months (range: 2 months–3 years). The HCPI for all dogs at follow-up was median 8 ± 7.30 (range: 5–25). Total HCPI was < 12 for 7/10 dogs and ≥ 12 for 3 dogs. Pelvic radiographs at 1 year confirmed osteointergration of the femoral stem implant and no evidence of implant subsidence or progression of osteoarthritis. However, there was some evidence of mild lucency of the acetabular bed around the prosthetic femoral head and mild peri-acetabular sclerosis in four cases. Conclusion Hip hemi-arthroplasty provides a clinically acceptable treatment for disabling disease of the coxofemoral joint with 10/11 patients achieving acceptable short-term clinical function. Long-term assessment of the hip hemi-arthroplasty and comparison with total hip replacement is indicated.

This cohort, retrospective study, in the Jávorszky Ödön Hospital, Vác, Hungary, involved 109 patients after total hip replacement. Methods: The applied questionnaires included the EQ-5D health-related quality of life scores, the Western Ontario and McMaster Universities Ostoearthritis Index (WOMAC) scores, the preoperative and the postoperative 5th year health characteristics. The severity of co-morbidities was graded in respect of clinical signs and pharmacological treatment. Results: The WOMAC values significantly improved in the examination period. However – in spite of the changes in EQ-5D –, it had no influence on adherence of feeling sick after total hip replacement. Among the co-morbidities, the cardiovascular diseases had a distinguished role because their prevalence and deterioration showed a close relationship with the subjective health-feeling of the patients. Conclusion: According to our study, we have to consider that in case of significant hypertension, ischemic heart diseases or chronic heart failure even the successful surgery will not improve the general sick-feeling of the patients.
