Injuries to the scapholunate interosseous ligament (SLIL) are the most common cause of carpal instability. A SLIL injury typically follows a fall on an outstretched hand, with the wrist in hyperextension, ulnar deviation and intercarpal supination. We hypothesize that repetitive axial loading on the wrist in hyperextension, during the reception and digging motions of volleyball, can lead to functional overloading of the SLIL. To identify patients and to determine the clinical history and surgical treatment performed, we analyzed hospital records, X-rays, electronic databases containing all the operations performed, and image files (including before and after surgery and follow-up)...

Rod Whiteley, Marc Oceguera
OBJECTIVES: Clinicians commonly interpret the findings of shoulder rotational ranges of motion using various approaches: an apparent reduction in dominant arm internal rotation ("GIRD"), a difference in total rotational range of motion-i.e. differences in the sum of internal and external rotational range (TRROM), and a combination of rotational ROM and torsional difference ("GIRD-torsion"). We have noticed that these approaches are being considered to provide equivalent estimates of shoulder rotational range...

PURPOSE: Exercise exerts various effects on the immune system, and evidence is emerging on its anti-inflammatory effects; the mechanisms on the basis of these modifications are poorly understood. Mitochondrial DNA (mtDNA) released from damaged cells acts as a molecule containing the so-called damage-associated molecular patterns and can trigger sterile inflammation. Indeed, high plasma levels of mtDNA are associated to several inflammatory conditions and physiological aging and longevity...
