“…In clinical practice a computer tomography (CT) scan is often used for evaluating EBI in cases to be surgically treated. 15 A 3D CT study by Lim et al . showed osteophytes predominating in the humeroulnar compartment, specifically in the anterior coronoid area (in 95%) and posteromedial compartment (in 86%).…”

Background Identifying the location and scale of radiographic changes in elbow bony impingement (EBI) is critical in formulating an appropriate diagnosis and treatment plan for such patients. The purpose of present study was to evaluate the intra-rater and inter-rater reliability of the new radiographic parameters, Anterior Impingement angle (AIa) and Posterior Impingement angle (PIa), for EBI. In addition, to determine if there was a relationship between radiographic parameters and clinical evaluation. Patients and methods Three raters of different levels of training evaluated the radiographs of 60 patients (30 in EBI group and 30 in normal group) twice, at least 2 weeks apart. Intra-rater and inter-rater reliabilities were calculated by Intraclass Correlation Coefficients (ICC) with 95% confidence intervals. Correlation between radiographic parameters and clinical evaluation was calculated by Pearson correlation coefficient. Results In both groups, intra-rater and inter-rater reliabilities were substantial. There were no significant differences in reliability between upper-hand expert surgeons and resident for either measurement. Good correlation was observed between impingement arcs and range of motion values. Conclusions Both AIa and PIa measurements demonstrated substantial intra-rater and inter-rater reliability for normal radiographs and in EBI patients. Good reliability, for either expert surgeons or residents in training, and good correlation between radiographic measurements and manual testing, appoints this method may be easily and reliably used in every day practice.

“…Juxta-and intra-articular osteoid osteomas are rare, but can occur in the olecranon fossa, the nidus located subchondrally creating a crater-like imprint at the bottom of the fossa [42]. A less convincing cause may be a posteromedial olecranon impingement, which is a common injury encountered in the throwing elbow, and is commonly associated with osteoarthritic changes including the possible presence of loose bodies and chronic stress fracture at the olecranon process [43,44]. However, there is no sign of any abnormal contact of the medial olecranon with the medial wall of the olecranon fossa in Cussac L3-088.…”

New Biological Data on a Gravettian Humerus from the Cussac Cave (Dordogne, France)

This article reports on a complete left human humerus from the Cussac Cave (Dordogne, France), dating to the Gravettian, or Mid-Upper Palaeolithic. This humerus is characterised by a very marked retroversion, significant intracortical porosity, an unusual morphology and orientation of the medial epicondyle, and a marked depression at the bottom of the olecranon fossa. These morphological features could be related to mechanical stimuli, but this is just an assumption given the absence of control data for many factors (e.g. age-at-death, sex, body mass, degree of asymmetry). Nevertheless, the description of this new discovery contributes significantly to our understanding of the range of variation of known Late Pleistocene skeletal morphology.
