Introduction: The World Health Organization announced the COVID-19 outbreak as a global pandemic on March 11, 2020. Despite the fact that orthopaedic departments are not considered first-line department in the war against pandemic, the pandemic has had a big effect on orthopaedic services. A few studies have found the pandemic effect on the orthopaedics field, but none have found the effect of a one-year pandemic, especially in Indonesia. This study aimed to know the effect of one-year COVID-19 on trauma of lower extremity at Orthopaedic Service in Prof Soeharso Top Referral Orthopaedic Hospital, Indonesia Materials and methods: It is a cross-sectional study. The study compared the population group during one year of the COVID-19 pandemic in Indonesia to the same period one year before. This study was conducted in Prof. Dr. R. Soeharso Orthopaedic Hospital, Surakarta, Indonesia from March 2019-February 2021. The subjects were patients of lower extremity trauma both surgical procedure and outpatient visit. Patients recorded on other orthopaedic service support installations like radiology, laboratory, or physiotherapy were excluded. Results: There was a significant reduction (54.9%) in total trauma of lower extremities patients in Prof Dr R Soeharso Orthopaedic Hospital, Surakarta, from 2146 (pre-COVID-19)to 968 (during COVID-19) in the March 2019-February2021 period. There was also a significant reduction (90.9%)in total cases outpatient visit in pre-COVID-19 compared toduring COVID-19 (p<0.05) and surgical procedures (39%)in pre-COVID-19 compare to the COVID-19 period(p<0.05). Conclusion: There was a significant reduction on trauma oflower extremities patients both outpatient visits and surgicalprocedures during pandemic COVID-19 than before the COVID-19 occurred.

Introduction: Periprosthetic joint infection (PJI) of the hip due to methicillin-resistant bacteria is difficult to treat and remain a challenge for arthroplasty surgeon. Material and Methods: Retrospective review was done to the patients who received two-stage revisions with an antibiotic loaded cement-spacer for PJI of the hip between January 2010 to May 2015. We found 65 patients (65 hips) with positive culture findings. Eight patients were lost to follow-up and excluded from the study. Among the rest of the 57 patients, methicillin-resistant infection (MR Group) was found in 28 cases. We also evaluate the 29 other cases that caused by the other pathogen as control group. We compared all of the relevant medical records and the treatment outcomes between the two groups. Results:The mean of follow-up period was 33.7 months in the methicillin-resistant group and 28.4 months in the control group (p = 0.27). The causal pathogens in the methicillinresistant group were: Methicillin-resistant Staphylococcus aureus (MRSA) in 10 cases, Methicillin-resistant Staphylococcus epidermidis (MRSE) in 16 cases and Methicillin-resistant coagulase-negative Staphylococcus (MRCNS) in two cases. The reimplantation rate was 92.8% and 89.6% in the methicillin-resistant and control group, respectively (p= 0.66). The rates of recurrent infection after reimplantation were 23.1% (6/26) in the methicillin-resistant group and 7.6% (2/26) in the control group (p= 0.12). The overall infection control rate was 71.4% (20/28) and 89.6% (26/29) in the methicillin-resistant and control group, respectively (p = 0.08). Both groups showed comparable baseline data on mean age, BMI, gender distribution, preoperative ESR/CRP/WBC and comorbidities. Conclusions: Two-stage revision procedure resulted in low infection control rate and high infection recurrency rate for the treatment of methicillin-resistant periprosthetic joint infection (PJI) of the hip. Development of the treatment strategy is needed to improve the outcome of methicillin resistant periprosthetic joint infection (PJI) of the hip.

Hip geometry abnormalities found in patients with hereditary multiple exostoses (HME) could promote premature hip joint degeneration which needs treatment. We report the case of a 45-year old male with right hip arthrosis who underwent two-incision minimally invasive (MIS-2) total hip arthroplasty (THA), with satisfactory outcome. This technique could be an alternative approach for performing THA in patients with hereditary multiple exostoses.
