Objective. To compare the surgical site infection (SSI) rate after primary total hip arthroplasty with the SSI rate after revision total hip arthroplasty. Design. Retrospective cohort study. Setting. Mayo Clinic in Rochester, Minnesota, a referral orthopedic center. Patients. All patients undergoing primary total hip arthroplasty or revision total hip arthroplasty during the period from January 1, 2002, through December 31, 2006. Methods. We obtained data on total hip arthroplasties from a prospectively maintained institutional surgical database. We reviewed data on SSIs collected prospectively as part of routine infection control surveillance, using the criteria of the Centers for Disease Control and Prevention for the definition of an SSI. We used logistic regression analyses to evaluate differences between the SSI rate after primary total hip arthroplasty and the SSI rate after revision total hip arthroplasty. Results. A total of 5,696 total hip arthroplasties (with type 1 wound classification) were analyzed, of which 1,381 (24%) were revisions. A total of 61 SSIs occurred, resulting in an overall SSI rate of 1.1% for all total hip arthroplasties. When stratified by the National Nosocomial Infection Surveillance (NNIS) risk index, SSI rates were 0.5%, 1.2%, and 1.6% in risk categories 0, 1, and 2, respectively. After controlling for the NNIS risk index, the risk of SSI after revision total hip arthroplasty was twice as high as that after primary total hip arthroplasty (odds ratio, 2.2 [95% confidence interval, 1.3-3.7]). In the analysis restricted to the development of deep incisional or organ space infections, the risk of SSI after revision total hip arthroplasty was nearly 4 times that after primary total hip arthroplasty (odds ratio, 3.9 [95% confidence interval, 2.0-7.6]). Conclusion. Including revision surgeries in the calculation of SSI rates can result in higher infection rates for institutions that perform a larger number of revisions. Taking NNIS risk indices into account does not eliminate this effect. Differences between primary and revision surgeries should be considered in national standards for the reporting of SSIs.

Total hip arthroplasty is most common reconstructive hip procedure in adults. In this surgery we replace some parts of the upper femur and acetabulum with biocompatible materials. The main goal of this surgery is to eliminate pain and regain full extent of joint motion, maintaining hip stability. Surgical technique, biomaterials, design of the prosthesis and fixation techniques have evolved with time adjusting to each other. After total hip arthroplasty patients? quality of life should be improved. There are many various postoperative complications. Some of them are fatal, and some are minor, which may become manifested years after surgery. Each next surgical procedure following previous hip surgery is associated with considerably lower chances to be successful. Therefore, in primary total hip arthroplasty, preoperative evaluation and preparation of patients are essential. Every orthopaedic surgeon needs to improve already adopted surgical skills applying them with precision and without compromise, with the main goal to achieve long-term durability of the selected implant. The number of total hip arthroplasties will also increase in future, and newer and higher quality materials will be used.

Background and Aims: Dislocation is one of the most common reasons for revision surgery after primary total hip arthroplasty. Both patient related and surgical factors may influence the risk of dislocation. In this study, we evaluated risk factors for dislocation revision after total hip arthroplasty based on revised data contents of the Finnish Arthroplasty Register. Materials and Methods: We analyzed 33,337 primary total hip arthroplasties performed between May 2014 and January 2018 in Finland. Cox proportional hazards regression was used to estimate hazard ratios with 95% confidence intervals for first dislocation revision using 18 potential risk factors as covariates, such as age, sex, diagnosis, hospital volume, surgical approach, head size, body mass index, American Society of Anesthesiology class, and fixation method. Results: During the study period, there were 264 first-time revisions for dislocation after primary total hip arthroplasty. The hazard ratio for dislocation revision was 3.1 (confidence interval 1.7–5.5) for posterior compared to anterolateral approach, 3.0 (confidence interval 1.9–4.7) for total hip arthroplasties performed for femoral neck fracture compared to total hip arthroplasties performed for osteoarthritis, 2.0 (confidence interval 1.0–3.9) for American Society of Anesthesiology class III–IV compared to American Society of Anesthesiology class I, and 0.5 (0.4–0.7) for 36-mm femoral head size compared to 32-mm head size. Conclusion: Special attention should be paid to patients with fracture diagnoses and American Society of Anesthesiology class III–IV. Anterolateral approach and 36-mm femoral heads decrease dislocation revision risk and should be considered for high-risk patients.

Background: There are currently a lack of investigations that characterised narcotic utilisation following revision total hip arthroplasty (THA). We sought to determine if immediate post-surgical opioid use was different between revision THA and primary THA. Methods: A single institution total joint arthroplasty database was used to identify adult patients who underwent revision THA or primary THA from 2016 to 2019. Morphine milligram equivalents (MME) were calculated for different time periods. Results: 6977 patients were identified, 89.72% primary THA and 10.28% revision THA. Aggregate opioid consumption was higher for revision THA patients (317.40 MME vs. 93.01 MME), as was opioid consumption in the first 24 hour and second 24-hour periods. Visual analogue pain (VAS) scores were significantly higher in the 0–12 hour postoperative and the 12–24 hours postoperative periods in the revision THA group. Conclusions: Patients undergoing revision THA had significantly higher narcotic utilisation than those undergoing primary THA, particularly in the first 24 hours postoperatively.

INTRODUCTION The aim of this study was to determine the incidence and outcome of dislocation after total hip arthroplasty at our unit. PATIENTS AND METHODS In total, 1727 primary total joint arthroplasties and 305 revision total hip arthroplasties were performed between 1993 and 1996 at our unit. We followed up 1567 (91%) of the primary hip arthroplasties and 284 (93%) of the revision hip arthroplasties at 8–11 years after surgery. Patients were traced by postal questionnaire, telephone interview or examination of case notes of the deceased. RESULTS The dislocation rates by approach were 23 out of 555 (4.1%) for the posterior approach, 0 out of 120 (0%) for the Omega approach and 30 out of 892 (3.4%) for the modified Hardinge approach. Of dislocations after primary total hip arthroplasty, 58.5% were recurrent. The mean number of dislocations per patient was 2.81. Overall, 8.1% of revision total hip arthroplasties dislocated. 70% of these became recurrent. The mean number of dislocations per patient was 2.87. The vast majority of dislocations occurred within 2 months of surgery. DISCUSSION To our knowledge, this is the largest multisurgeon audit of dislocation after total hip arthroplasty published in the UK. The follow-up of 8–11 years is longer than most comparable studies. The results of this study can be used to inform patients as to the risk and outcome of dislocation, as well as to the risk of further dislocation.

Vieni autoriai pripažįsta cementinio, kiti – mechaninio tvirtinimo metodiką. Abiem atvejais vėlyvieji rezultatai yra panašūs. Kiekviena metodika tam tikru endoprotezuoto sąnario laikotarpiu išryškina jai būdingas problemas. Mūsų darbo tikslas – įvertinti vėlyvuosius mišraus ir mechaninio tvirtinimo klubo sąnario pirminio endoprotezavimo rezultatus po operacijos praėjus 5–10 metų. Ligoniai ir tyrimo metodai 1993–1998 metais VGPUL Ortopedijos, traumatologijos ir plastinės chirurgijos klinikoje buvo operuoti 36 ligoniai, kuriems buvo atliktos 39 pirminės klubo sąnario endoprotezavimo operacijos naudojant Bi-Metric mechaninio ir mišraus tvirtinimo endoprotezus (EP). Į tyrimą įtraukti 27 ligoniai (29 endoprotezai – 18 mechaninio ir 11 mišraus tvirtinimo), 2002–2003 metais atvykę pasitikrinti. Vidutinis pacientų su mechaninio tvirtinimo protezais stebėjimo laikas (mediana) siekė 7 metus, o su mišraus tvirtinimo – 5 metus. Visiems atvykusiems pacientams buvo atliktos ir įvertintos priekinės abiejų klubo sąnarių rentgenogramos, nustatyta klubo sąnario funkcija pagal Harris Hip Score skalę. Rezultatai 2002–2003 m. ištirta 29 (80%) iš 36 ligonių, operuotų 1993–1998 m. Rentgenologinių tyrimų rezultatai parodė, kad aplink mechaninio tvirtinimo komponentus linijinės demarkacijos nėra. Visi komponentai buvo stabilūs. Kaulas įaugo į mechaninio tvirtinimo komponentus 100% atvejų. Įvertintos osteolizinio proceso aplink gūžduobinį ir šlaunikaulinį komponentus ypatybės, polietileninio intarpo susidėvėjimo prognozės veiksniai atsižvelgiant į endoprotezo tipą, ektopinė osifikacijos įtaka vėlyviesiems klubo sąnario funkciniams rezultatams. Išvados Įvertinti pagal HHS skalę mechaninio ar mišraus tvirtinimo endoprotezavimo rezultatai po 5–10 metų yra geri ir labai geri. Lyginant rentgenologinius pokyčius aplink gūžduobinį ir šlaunikaulinį komponentus matyti, kad pokyčiai aplink mechaninio ir cementinio tvirtinimo šlaunikaulinius komponentus yra gerokai mažesni negu aplink gūžduobinius. Statistiškai patikimo skirtumo tarp polietileno intarpo susidėvėjimo ir panaudoto endoprotezo tipo nebuvo. Gūžduobinio ir šlaunikaulinio komponentų osteoliziniai procesai yra besimptomiai. Šie procesai ir 76% atvejų nustatyta ektopinė osifikacija neturi įtakos geriems ir labai geriems vėlyviesiems operuoto klubo sąnario funkciniams rezultatams. Prasminiai žodžiai: pirminis klubo sąnario endoprotezavimas, mechaninio tvirtinimo endoprotezai, mišraus tvirtinimo endoprotezai. Primary hybrid and cementless total hip arthroplasty. 5 to 10 year follow-up results Jaunius Kurtinaitis, Narūnas Porvaneckas, Manvylius Kocius, Rimvaldas Broga Background / objective The major issue of hip arthroplasty is the wearout or loosening of the acetabular component. Some authors prefer cemented and others cementless hip arthroplasty. In both cases the outcome is similiar. Each method in different periods has its own problems. The aim of the study was to evaluate the late outcome of primary cementless and hybrid total hip replacement 5–10 years after operation. Patients and methods There were 36 patients operated on and 39 operations of primary total hip arthroplasty performed using Bi-Metric hybrid and cementless endoprostheses in 1993–1998. The study included 27 patients (29 endoprostheses) who responded to invitation in 2002–2003. Anteroposterior radiographs of the hip joints were performed for the patients and the functional outcome was evaluated using the Harris Hip score scale. Results During 2002–2003 investigation was carried out on 29 (74%) of 36 hip arthroplasties performed in 1993–1998. Analysis of the data showed no radiolucency signs around the cementless fixation components. All of the components were stable. Bone ingrowth into the cementless prosthesis components was observed in 100% of cases. The osteolysis zones around the acetabular and femoral components were related to the wearout of polythene insertion, but it was asymptomatic. There was no reliable difference between polythene insertion wearout and the type of prosthesis. Ectopic ossification was observed in 76% of cases. Conclusions The study based on HHS score revealed good and very good results 5–10 years after operation. They were comparable with the findings in similar studies. Rentgenological features indicated that there were less alterations around the femoral component compared to the acetabular. Osteolysis around the femoral and acetabular components was asymptomatic and ectopic ossification found in 76% of cases did not interfere with the good functional results.

Background and Objectives: Femoral head and liner exchange is an established treatment for polyethylene wear but has had a more limited role in the treatment of other conditions including dislocation, because of concerns about an increased postoperative dislocation rate. Some authors have considered dislocation associated with polyethylene wear to be a contraindication for this procedure. Materials and Methods: Our retrospective review evaluated the outcome of head and liner exchange in a small consecutively operated heterogeneous cohort of 20 patients who presented with dislocation unrelated to trauma, component malposition or component loosening. Of this group, 12 had prior primary total hip arthroplasty, and 8 had prior revision total hip arthroplasty, and included 4 patients with prior revision for dislocation. Mean follow-up was 6 ± 3.5 years (range 1–145 months). Results: Kaplan–Meier analysis revealed a revision-free implant survival from any cause of 80% (confidence interval 95%:64.3–99.6%) at 5 years after head and liner exchange (index surgery). At final follow-up, 83.3% of patients (n = 10) with prior primary total hip arthroplasty and 62.5% of patients (n = 5) with prior revision total hip arthroplasty, had not required subsequent revision for any cause. None (0%) of the primary total hip arthroplasty group and 3 (38%) of the revision arthroplasty group had required revision for further dislocation. Of the eight revision arthroplasty patients, four had a prior revision for dislocation and three of these four patients required further revision for dislocation after index surgery. The fourth patient had no dislocation after index surgery. One additional patient who had prior revision surgery for femoral component fracture suffered dislocation after index surgery, but was successfully treated with closed reduction. Conclusions: In our study population, femoral head and liner exchange was an effective treatment option for patients with prior primary total hip arthroplasty and also for a highly select group of revision total arthroplasty patients with no prior history of dislocation. Femoral head and liner exchange does not appear to be a viable treatment option for patients who have had revision total arthroplasty after prior dislocations.
