The elbow is the second most commonly dislocated joint in adults. Simple lateral dislocation of the elbow joint is a rare traumatic injury, and successful closed reduction is difficult and even rarer. Our proposition is to report this rare case of traumatic simple lateral dislocation treated with closed reduction under sedation emphasizing the use of this simple technique initially in order to avoid possible complications with general anesthesia and surgery.

Avascular necrosis (osteonecrosis) is a disease that results from the temporary or permanent loss of blood supply to the bone. Synchrotron FT-IR microspectroscopy has been used to study the changes in mineral and matrix content of necrotic bone. FT-IR spectroscopic analysis revealed that in necrotic bone the relative mineral/matrix ratio decreased. Spectroscopic differences were observed between normal and necrotic bones. The noticeable differences may have important implications for analyzing and evaluating death bone.
