The purpose of this study was to compare latissimus dorsi tendon transfer (LDTT) and arthroscopic superior capsular reconstruction (SCR) to determine if one is superior to the other regarding improvement in range of motion (ROM) or patient-reported outcomes (PROs). A multicenter, retrospective cohort study was conducted on 43 patients with an irreparable, posterosuperior rotator cuff tear who underwent either LDTT or SCR. Preoperative and postoperative forward flexion and external rotation, as well as PROs including ASES, VAS, and SSV, were assessed. Student t-test and chi-square statistical analyses were performed. 16 LDTT, at mean follow-up of 18 months, and 27 SCR, at mean follow-up 15 months, were studied. Mean active forward flexion significantly improved from 85.2° to 137.6° in the SCR cohort ( ). SCR patients demonstrated a significantly greater increase in forward flexion as compared to LDTT patients (52.4° vs 14.1°, ). Mean active external rotation amongst the LDTT group significantly improved from 41.7° to 61.5° ( ). LDTT demonstrated significantly greater improvement in external rotation as compared to SCR (19.4° vs 0.8°, ). There were no significant differences in reported ASES, VAS, or SSV scores. This study demonstrates successful clinical and patient-reported outcomes with both LDTT and SCR for irreparable, posterosuperior rotator cuff tears, with greater improvement in forward flexion with SCR and greater improvement in external rotation with LDTT. This study demonstrates successful clinical and patient-reported outcomes with both LDTT and SCR for irreparable, posterosuperior rotator cuff tears, with greater improvement in forward flexion with SCR and greater improvement in external rotation with LDTT.Consistent diagnosis of periprosthetic infection in total joint arthroplasty continues to elude the orthopedic surgeon because no gold standard test exists. Therefore clinicians must rely on a combination of tests to help aid the diagnosis. The expanding role of biomarkers has shown promising results to more accurately diagnose an infection when combined with clinical suspicion and bacterial culture testing. This paper reviews the diagnostic capabilities of the most current serum and synovial biomarkers as well as next generation sequencing in the setting of periprosthetic joint infection. Future research and high-powered studies will be necessary to determine sensitivity and specificity of each biomarker.The distal radioulnar joint (DRUJ) prostheses have been available for many years and despite their superior outcomes compared to conventional DRUJ reconstructions in both short and long-term follow-ups, they have not become as popular as common hip and knee prostheses. In the current review article, at the first step, we discussed the applied anatomy and biomechanics of the DRUJ, and secondly, we classified DRUJ prostheses according to available literature, and reviewed different types of prostheses with their outcomes. Finally we proposed simple guidelines to help the surgeon to choose the appropriate DRUJ prosthesis.Total knee replacement (TKR) is a growing attractive treatment for a degenerative knee disease. However, there remain some certain devastating complications to be discussed with patients preoperatively, including limb amputation. This systematic review aimed to determine the rate of amputation following TKR. In this study, the literature was searched up to 2019. The papers were included in which knee amputation was reported following TKR. The primary search concluded the articles from EMBASE, SCOPUS, PubMed, Web of Science, MEDLINE, OvidSP, CINAHL, EBSCO, Web of Science™, and CENTRAL. After screening and excluding case reports, 40 papers were included in the present study. The present review showed that amputation is a real end result of knee replacements either in primary or revision knee arthroplasties, which needs to be discussed with patients for their decision-making. Prevalence of amputation in terms of failure or complications after TKR procedures was estimated between 0.1-10% in different studies , with 5.1% amputation rate in infected TKR and 0.025% amputation rate in primary TKR as a result of infection in our review. Deep infection was the main cause of amputation. Vascular complications and fractures associated with bone loss and compartment syndrome were other reasons for amputation. Given the possible coexistence of infection by the SARS-CoV-2 with other seasonal infections, the aim is to identify differential symptoms. The role of children in intrafamily contagion and the sensitivity of reverse transcriptase polymerase chain reaction (RT-PCR) in an area with low community transmission has been studied. Cross-sectional observational study. Patients between 0-15 years studied by RT-PCR technique due to clinical suspicion of infection by SARS-CoV-2 virus in the months of March-May 2020. Survey on symptoms and contacts. Determination of Anti-SARS-CoV-2 antibodies at least 21 days after the RT-PCR test. 126 patients were included, 33 with confirmed infection and age mean 8.4 years (95% CI 6.8-10.5) higher than not infected. Fever was the most common and with greater sensitivity. The differences found were a greater frequency of anosmia ( =.029) and headache ( =.009) among children infected with a specificity of 96.7% and 81.5% respectively. There were no differences in the duration of the symptoms. 81.8% of those infected were probably infected in the nucleus 85.2% by a parent who worked outside the home. The sensitivity of RT-PCR was 70.9% and its negative predictive value 91.1%. The clinical picture is nonspecific and the symptoms more specific difficult to detect in younger children. Children had a reduced role in the intrafamily transmission. https://www.selleckchem.com/products/bos172722.html The sensitivity of RT-PCR could be related to a less contagiousness in children after one week of infection.
