RESUMO
INTRODUCTION: The incidence of periprosthetic joint infection (PJI) in hip surgeries has significantly decreased thanks to intravenous antibiotic prophylaxis. However, in patients colonized with methicillin-resistant Staphylococcus aureus (MRSA) or those at risk of colonization, it is necessary to include vancomycin in the prophylaxis. Intraosseous (IO) administration of vancomycin could enhance its effectiveness in total hip arthroplasty (THA). MATERIALS AND METHODS: A retrospective study was conducted between March and December 2023 involving 53 patients scheduled for primary THA with colonization risk factors. The median age of the patients was 67 years (range 61 to 75), and all received treatment with intraosseous vancomycin (500 mg). Detailed records and documentation of complications during hospitalization and the first three months post-surgery were maintained. As a secondary outcome measure, the incidence of PJI was explored. RESULTS: We administered 500 mg of intraosseous vancomycin, injected into the greater trochanter, along with standard intravenous (IV) prophylaxis. The incidence of complications was 1.64%. The periprosthetic joint infection rate at 90 days was 0%. CONCLUSIONS: Intraosseous administration of low-dose vancomycin in total hip arthroplasty for patients at risk of MRSA colonization, combined with standard IV prophylaxis, was shown to be safe and did not present significant adverse effects. Furthermore, this strategy eliminates the logistical challenges associated with timely vancomycin administration. LEVEL OF EVIDENCE IV: Case Series.
RESUMO
OBJECTIVE: To analyze the clinical, quality of life, and healthcare quality outcomes obtained in a series of patients undergoing total hip arthroplasty (THA), who were empowered and monitored using the AVIP application. These results will be compared with a control group followed through a standard protocol. MATERIAL AND METHOD: Randomized clinical trial with parallel groups involving patients with an indication for THA. Clinical variables were measured and compared using the WOMAC and mHHS, pain assessed by the VAS, quality of life with the SF-12 test. Walking capabilities were analyzed using the Functional Gait Assessment Scale, along with satisfaction levels assessed through the SUCE questionnaire, and perceived anxiety levels related to the process. RESULTS: A total of 68 patients were evaluated, with 31 patients in the AVIP group and 33 in the Control group completing the follow-up. Both groups demonstrated improvement in clinical outcomes based on the WOMAC and mHHS hip tests, a reduction in perceived pain, and an enhancement in quality of life according to the SF-12 test. Patients in the AVIP study group exhibited non-inferiority in clinical outcomes and satisfaction compared to the control group, as well as lower anxiety levels and improved walking capabilities after the first month of follow-up. Notably, 82.25% of the follow-up visits for this group were conducted remotely. CONCLUSION: The implementation of a mHealth application like AVIP can be safely offered to selected patients undergoing hip arthroplasty, enabling effective monitoring and providing continuous information and training.
RESUMO
Due to their low friction index, hip arthroplasties with metal-metal (M-M) friction torque have been an attractive option in young patients with high functional demand, currently they have suffered a decrease in their use due to the complications of some models and physiological reactions adverse reactions related to the elevation of metal ions in the blood. Our objective is to review the patients with M-M pair operated in our centre, correlating the ion level with the position of the acetabular component and with the size of the head. MATERIAL AND METHODS: Retrospective review of 166 M-M hip prostheses operated between 2002 and 2011. Sixty five ruled out for different causes (death, loss of follow-up, no current ion control, no radiography or others), leaving a sample of 101 patients to be analysed. Follow-up time, cup inclination angle, blood ion level, Harris Hip Score (HHS), and complications were recorded. RESULTS: One hundred and one patients (25 women and 76 men), 55 years of average age (between 26 and 70), of these 8 were surface prostheses and 93 total prostheses. The mean follow-up time was 10 years (between 5 and 17 years). The mean head diameter was 46.25 (between 38 and 56). The mean inclination of the butts was 45.7° (between 26° and 71°). The correlation force between the verticality of the cup and the increase in ions is moderate r=0.31 for Cr and slight r=0.25 for Co. The correlation force between head size and ion increase is weak and inverse r=-0.14 for Cr and r=0.1 for Co. Five patients (4.9%) required revision (2 [1%] due to increased ions with pseudotumor). The mean time to revision was 6.5 years in which the ions increased. The mean HHS was 94.01 (between 55.8 and 100). In the review of patients, we found 3 with a significant increase in ions who had not followed controls, all 3 had an HHS of 100. The angles of the acetabular components were 69°, 60° and 48° and the diameter of the head was 48.42 and 48mm, respectively. DISCUSSION AND CONCLUSIONS: M-M prostheses have been a valid option in patients with high functional demand. A bi-annual analytical follow-up is recommended, since in our case we have detected 3 patients with HHS 100 who presented unacceptable elevation of cobalt >20µm/l (according to SECCA) of the ions and 4 with very abnormal elevation of cobalt ≥10µm/l (according to SECCA), all of them with cup orientation angles >50°. With our review we can conclude that there is a moderate correlation between the verticality of the acetabular component and the increase in blood ions and that the follow-up of this patient with angles >50° is essential.
RESUMO
BACKGROUND: Postoperative pain after total hip arthroplasty can affect postoperative rehabilitation and delay hospital discharge. The objective of this study is to compare pericapsular nerves group (PENG) block with pericapsular infiltration (PAI) and plexus nerve block (PNB) for postoperative pain management, response to physical therapy, opioid consumption, and length of hospital stay after a primary total hip arthroplasty. METHODS: Randomized clinical trial of parallel and blinded groups was performed. Sixty patients who underwent elective THA between December 2018 and July 2020 were randomized into the different groups (PENG, PAI and PNB). The visual analog scale was used to assess pain; and motor function was measured with the Bromage scale. We also record opioid usage, length of hospital stay, and related medical complications. RESULTS: Pain level at discharge was similar in all groups. Hospital stay was 1 day shorter in the PENG group (p<0.001) and they also had lower opioid consumption (p=0.044). Optimal motor recovery was similar in the groups (p=0.678). Pain control when performing physical therapy was better in the PENG group (p<0.0001). CONCLUSIONS: PENG block is an effective and safe alternative for patients undergoing THA as it reduces opioid consumption and hospital stay compared to other analgesic methods.
RESUMO
BACKGROUND AND AIM: Different authors have demonstrated the usefulness of the histological analysis in the diagnosis of prosthetic joint infection; however, its clinical validity is still controversial. The aim of this article is to describe and analyse the clinical validity of histological analysis in the diagnosis of prosthetic infection in patients undergoing hip or knee prosthetic replacement. MATERIAL AND METHODS: We present a retrospective study including 133 hip and knee prosthetic replacements performed in our centre between 2008 and 2020. A descriptive, bivariate statistical analysis was performed and the clinical validity of the histological analysis was determined. OUTCOMES: The clinical validity of the intraoperative histology offered a sensitivity of 48%, a specificity of 91%, a positive predictive value of 55% and a negative predictive value of 88%. CONCLUSIONS: The determination of the clinical validity of histological analysis shows a high specificity. This analysis is an appropriate diagnostic tool for detecting healthy patients, with no infection.

RESUMO
INTRODUCTION: Hip resurfacing arthroplastys are a valid alternative for the treatment of degenerative hip disorders in young adults. Poor results and adverse soft tissue effects have been reported with high levels of chromium and cobalt, limiting its indications. Objective is to analyze clinical and functional survival results of the Durom system 10 years after its implementation in a public hospital. The hypothesis is that better results and survival are obtained in patients selected according to FDA criteria. MATERIAL AND METHODS: Retrospective cohort study of 83 patients, 91 hips in 76 men and 7 women operated between 2005 and 2013 with Durom-type prostheses. Demographic study, diagnosis, BMI, radiological study, serum chromium cobalt levels, functional assessment according to MPD and HSS, complications and survival at 10 years of follow-up. A cohort of active men under 65 years of age and heads over 48mm is selected. RESULTS: Follow-up time of 121 months with a range from 84 to 176 months. With a mean age of 52.78 years, with 4 deaths and loss of follow-up of 3 cases. There are 12 complications that require reoperation (14.45%) with 2 chronic infections, 4 femoral neck fractures, 4 acetabular loosening and 2 cases of pseudotumors. With an overall survival of 85.4% (71-91.9) and 87.85% (85.5-91.1) in the absence of infection. No statistical relationship between complications and neck narrowing and the angles of inclination of the components. In selected patients, 69 men and 73 hips, we obtained an overall survival of 91.82% and excluding infection of 93.18% at 10 years. CONCLUSIONS: The indication of the Durom system in the treatment of degenerative processes in selected active young patients presents better results and survival at 10 years, although somewhat lower than other highly indicated veneering models.
RESUMO
MAIN AIM: To know the result of the Girdlestone resection arthroplasty in the treatment of the infected hip arthroplasty. SECONDARY AIMS: To analyze the effectiveness in the control of pain and infection, the functional outcome and to contrast factors correlated with the final result. PATIENTS AND METHODS: Case series with a total of 17 patients. The control of the infection was assessed according to the presence or absence of sinus, and the clinical status using EuroQol 5D scale, residual pain and limb length discrepancy. OUTCOMES: The most common infecting germ at the time of removal of the arthroplasty was Staphylococcus CN and one patient presented infection by Candida albicans. In 2 patients the draining sinus persisted. The residual dysmetria was 5.24cm. In the EQ-5D scale, the most affected dimensions were mobility, need for help for self-care and ability to carry out activities of daily life. 8 patients maintained, pain levels worse than 4 in the VAS. The variables of dysmetria were correlated inversely with health index (-0,54) and self-perceived general health status (-0,45). CONCLUSIONS: The Girdlestone resection arthroplasty is an alternative in the treatment of the infected hip arthroplasty. Patient perception is inversely corelated to residual dysmetria. The dysmetria is greater in women and in ages over 65 years.
RESUMO
OBJETIVES: 100 mcg intrathecal morphine (ITM) for hip arthroplasty provides adequate functional recovery and reduces associated complications but is not exempt from opioid-related adverse effects. We evaluate efficacy of a reduced dose of ITM (80 mcg) in terms of anesthetic quality, postoperative analgesia, complication rates and early recovery. METHODS: Case-control study. Patients under hip arthroplasty were treated on a specific protocol, using neuraxial anesthesia with hyperbaric bupivacaine 10.5-13.5 mg plus 80 mcg ITM versus controls with 100 mcg ITM. Demographic variables, intra and perioperative course were extracted from medical records. Pain severity and morphine associated complications were blindly assessed at regular intervals postoperatively. p < 0.01 were considered significant. RESULTS: 82 patients were analyzed. Mean age was 64.21 years, 62.20% women and 70.73% ASA-2. Main endoprosthesis indication was arthrosis (58.53%). No statistically significant differences in demographic and operative data were found between groups, including surgical time, ambulation time, length of stay, and patient satisfaction for pain management. Mean VAS for pain during first 24 hours was 0.24 for the low ITM group and 0.22 for control. Rescue intravenous morphine was the same between groups. Compared to 80 mcg ITM, 100 mcg showed trends for higher complication rates for respiratory depression (OR 2.58, CI 95% 0.45-14.54, p = 0.28), nausea without vomiting (OR 1.82, CI 95% 0.82-4.01, p = 0.13), urinary retention (OR 2.02, CI 95% 0.88-4.61, p = 0.09) and significantly higher rates of pruritus (OR 3.55, CI 95% 1.61-7.82, p < 0.01). CONCLUSIONS: 80 mcg ITM during spinal anesthesia for hip arthroplasty provided comparable postoperative analgesia and lower incidence of opioid-related adverse effects.
