Abstract:

The tenoscopic examination of the podotrocheal bursa has been published several years ago, however these examinations and therapeutic interventions has been performed in general anaesthesia with a normal sized arthroscope with a diameter of 5 millimetres. During our research we examined the feasibility of a novel needle-bursoscopic technique that can be carried out in standing position, with local anaesthesia on sedated horses.

In our study we examined nine horses with healthy podotrochlear bursa on both front limbs (n=18). We performed a diagnostic bursoscopy of the podotrochlear bursa in standing position with sedation and local anaesthesia. The exploration of the podotrochlear bursa was from transthecal approach through the digital flexor tendon sheath or direct approach and from the medial or the lateral side after filling up the bursa with anaesthetic solution. After a two month follow-up period the horses were euthanized. Dissection of the limbs was performed to examine the nature and position of the iatrogenic damages.

On the first four days after the procedure the horses developed 0-3/5 lameness but they went sound on the 14th day. The bursoscopy was feasible in 16 cases where we could examine the anatomical structures in the podotrochlear bursa. During the bursoscopy fibrillation of the fibrous cartilage on the flexor surface of the navicular bone and the dorsal surface of the deep digital flexor tendon was visible. The post mortem macroscopic examination showed overgrowth of the synovial membrane and adhesion between the deep digital flexor tendon and the flexor surface of the navicular bone.

According to our research we can say that the needle-bursoscopy in standing position is feasible and the anatomical structures in the bursa can be identified, however the technique needs further evaluation because of the bursoscopic findings and the postoperative lameness.
