Injury of the brachial artery accompanying simple closed elbow dislocation: a case report.

Background: Elbow dislocation is the second common dislocation in adults, after the shoulder. The anatomical proximity to the joint of the brachial artery could lead to concomitant vascular injuries, even if their occurrence remains very rare.

Method: It is reported the case of a right-hand-dominant  42-year-old man who sustained a simple closed  posterior elbow dislocation of  his left elbow, associated to a complete brachial artery rupture.

Patient specific instrumentation in total knee arthroplasty.

Background And Aim Of The Work: The international literature and analysis of the prosthetic registers highlight a significant relationship between the alignment of the components and the survival of prosthetic implants of the knee. The patient specific instrumentation (PSI) technology exploits the data obtained with the MRN for the production of cutting blocks (CB) useful to a TKA. Revisiting the recent international literature, comparing the results of the conventional method and PSI, numerous studies confirm a statistically significant difference of inliers (± 3 degrees) for HKA.
