Background: The purpose of our study was to evaluate inter-observer reliability of the Three-Column classifications with conventional Schatzker and AO/OTA of Tibial Plateau Fractures.
Methods: 50 cases involving all kinds of the fracture patterns were collected from 278 consecutive patients with tibial plateau fractures who were internal fixed in department of Orthopedics and Trauma III in Shanghai Sixth People's Hospital. The series were arranged randomly, numbered 1 to 50. Four observers were chosen to classify these cases. Before the research, a classification training session was held to each observer. They were given as much time as they required evaluating the radiographs accurately and independently. The classification choices made at the first viewing were not available during the second viewing. The observers were not provided with any feedback after the first viewing. The kappa statistic was used to analyze the inter-observer reliability of the three fracture classification made by the four observers.
Results: The mean kappa values for inter-observer reliability regarding Schatzker classification was 0.567 (range: 0.513-0.589), representing "moderate agreement". The mean kappa values for inter-observer reliability regarding AO/ASIF classification systems was 0.623 (range: 0.510-0.710) representing "substantial agreement". The mean kappa values for inter-observer reliability regarding Three-Column classification systems was 0.766 (range: 0.706-0.890), representing "substantial agreement".
Conclusion: Three-Column classification, which is dependent on the understanding of the fractures using CT scans as well as the 3D reconstruction can identity the posterior column fracture or fragment. It showed "substantial agreement" in the assessment of inter-observer reliability, higher than the conventional Schatzker and AO/OTA classifications. We finally conclude that Three-Column classification provides a higher agreement among different surgeons and could be popularized and widely practiced in other clinical centers.

Derby Fertility Unit, Royal Derby Hospital, University Hospital of Derby and Burton, Derby DE22 3NE, UK.
: The aim of this study is to assess the inter- and intra-observer reproducibility of the identification of direct and indirect ultrasonographic features of adenomyosis as defined by the revised Morphological Uterus Sonographic Assessment (MUSA) consensus (2022). : A cohort of 74 women, aged 18 to 45, were recruited from the recurrent miscarriage and general gynaecology clinic at a university-based fertility centre. All the participants underwent 2D and 3D transvaginal Ultrasound scan (TVS) examination in the late follicular and early luteal phase.

Department of Ophthalmology, University Hospital Tübingen, Germany.
Purpose: The study aimed to assess the reliability of tele-education in training a Malawian ophthalmology resident to interpret optical coherence tomography (OCT) images of patients with macular conditions.
Methods: This was a retrospective analysis of 1000 macula-centered OCT image series from 1000 eyes of 1000 consecutive patients from Malawi, which involved initial interpretation by a German retina specialist (observer 1) (T). Observer 1 then trained a Malawian resident (observer 2) via email, and observer 2 independently interpreted images at T, followed by face-to-face training in Malawi and reinterpretation at T and T (3-month intervals).

Background: The Oxford Shoulder Score (OSS) is a well-established and extensively utilized shoulder score translated into Western and Asian languages for use in respective countries. Our study aimed to translate, cross-culturally adapt, and psychometrically validate the OSS in the Tamil language community.
Methods: The translation and cross-cultural adaptation were conducted according to previously established standards.
Displaced cortical vein sign on CT in infants: a reliable predictor to distinguish low-attenuation subdural collections from benign enlargement of subarachnoid spaces.

Differentiating benign enlargement of subarachnoid spaces (BESS) from low-attenuation subdural collections on CT imaging of infants can be challenging. This distinction is crucial in infants, as subdural collections may raise the concern for abusive head trauma (AHT). To evaluate the utilization of the displaced cortical vein sign on CT as a predictor of pathological subdural collections confirmed by MRI and to assess the reproducibility of this finding among radiologists with different levels of clinical experience.

Background: The influence of advanced imaging modalities on the reliability of 2018 AO/OTA classification and detection of features contributing to fracture instability have not been adequately studied in the literature.
Methods: This prospective study was conducted to assess the reliability of 2018 AO/OTA classification for trochanteric femoral fractures, and features of instability in 50 patients using radiographs, multiplanar reformats (MPR), and 3D-reconstruction with fracture segmentation (3DR-FS) by 3 observers on 2 occasions at an interval of 4 weeks.
Results: Mean inter-observer reliabilities on radiographs, MPR, 3DR-FS were 0.
