Modified Technique for Medial Patellar Desmotomy in Donkey

In our study, the modified technique of medial patellar desmotomy in donkey was performed on 10 apparently adult healthy alive donkeys of both sexes in addition other, two cadavers. In concern to the upward fixation of patella in donkeys as native animals in Upper Egypt which recorded high incidence of the disease more than found in northern areas. Medial patellar desmotomy is the preferable surgical procedure of choice for treating such problem. Contrary to the standard technique of treatment, the study aimed to introduce a modified easier, less expensive and field applicable desmotomy method. our study give a full detailed applied anatomical description of the patellar ligaments specially the medial one as well as its boundaries; osseous and muscular attachments as well as the extension of the joint capsule. The medial patellar ligament was the longest and the weakest among others on the other hand the middle one was the shortest and of considerable thickness. The best and ideal side for desmotomy was determined in order to avoid massive drawbacks as piercing the joint capsule or even cutting the tendon of the sartorius muscle. Generally nearly similar anatomical results were observed with the most of authors and the donkey was an ideal animal in equine experiment and the study allow the anatomists for further comparative anatomical researches.
