RESUMO
To evaluate the feasibility of performing needle arthroscopy of the scapulohumeral joint and bicipital bursa in standing horses by using the thoracic limbs of euthanized horses. To that purpose, this experimental study was designed. Ten thoracic limbs, five left and five right from euthanized horses were retained in an upright position to simulate a standing horse. The craniolateral and lateral scapulohumeral arthroscopic portals were used to access the articular structures. A third (caudal) portal was also identified and described. The degree of difficulty in accessing the articular space and the optic maneuverability within the joint were compared between portals. The needle arthroscopy image lacks in quality, but the procedure was considered useful as a diagnostic aid for examination of the scapulohumeral joint of horses. Needle arthroscopy of the bicipital bursa was not possible. Needle arthroscopy has a great diagnostic potential for lesions in the scapulohumeral joint of horses. A new access (caudal) to the scapulohumeral joint of horses has been identified.
