RESUMO

This study was carried out in order to evaluate the viability of a new arthroscopic approach of the palmar recess of the the interphalangeal joint in horses through the synovial sheath that involves the digital flexor tendon. The purposes of the study were to provide safety and efficiency during arthrocentesis, to allow effective visualization of the anatomical structures and provide means for the manipulation of arthroscopic instruments. Initially, 20 anatomic parts corresponding to the forelimbs of 10 horses were used. Sets numbers 1 through 5 formed Group I in wich a medial surgical approach was performed. Sets numbers 6 through 10 formed Group II, in which there was a lateral surgical approach. Later, the procedure in experimental animals was analyzed. This analysis was done using the proposed arthroscopic technique in 6 distal interphalangeal joints of the forelimbs of three horses (GIII). There was no previously disease diagnosed through physical and radiographic exams. The procedures in Group III were done under put general anesthesia in the lateral recumbence position and all the animals were under observation during six weeks. In the post-operative period a physical and contrasted radiographic exams were done to evaluate the recovery as well as the necessary healing time of the membrane between the digital sheath and distal interphalangeal joint. The technique responded positively to its objectives offering a new alternative to the approach of the palmar recess in the distal interphalangical joint in horses
