Evaluation of the comparative strength of long head biceps tenodesis

This article discusses the important anatomical features of long head of the biceps tendon, gives examples of the main surgical pathologies and possible options for surgical treatment. A comparative evaluation of the strength of tendon fixation by using a dynamometer in different parts of the proximal humerus with the interference screw with standard technique in the tunnels of different diameters, as well as using a suture anchor with a double lasso loop suture was made. As a result of the comparative testing, it was found that the strength characteristics of the fixation performed using an interference screw and a suture anchor are comparable and provide a sufficiently high fixation strength of the tendon. As a result, indications for the use of one or another type of fixation in patients of different age groups with the presence or absence of pathology of the accompanying structures of the shoulder joint have been determined. It has been established that for patients without concomitant injury of the elements of the rotator cuff, as well as to the category of people whose load does not imply an overhead intension, it is sufficient to use the method of fixing the tendon with an interference screw. In other cases, the use of suture anchor is recommended. There are indications of possible complications when using one of these methods of fixation and ways for their prevention.
