Synoviocoeles associated with the tarsal sheath: description of the lesion and treatment in 15 horses.

This study aims to provide a detailed description of a certain condition affecting horses, known as ‘synoviocoeles’ related to the tarsal sheath, along with a suggested method for its treatment. The researchers retrospectively evaluated case records and diagnostic images of 15 horses suffering from synoviocoeles, identified the anomaly, and treated it. It was found that enlarging the defect in the tarsal sheath wall through endoscopy, offered positive clinical results in two-thirds of the horses.

Study Description and Objective

• The main objective was to provide a description of the clinical, ultrasonographic and endoscopic features related to a defect in the wall of the tarsal sheath, and define the resulting cavity. This is in line with an attempt to better define and classify ‘false thoroughpins’, which may be caused by such defects and can be treated by removing them.

Methods

• The researchers retrospectively reviewed case records and diagnostic images of horses affected by synoviocoeles associated with the tarsal sheath. Information regarding follow-ups was also collected and evaluated.

Results and Conclusions

• Of the 15 horses diagnosed with synoviocoeles, all were managed similarly and 10 had a clinical resolution and were able to return to work.
• The researchers concluded that the previously used terminology for describling lesions involving the tarsal sheath does not accurately describe the condition and they propose the use of the term ‘synoviocoele’.
• It was also found that enlarging the sheath wall defect through endoscopy led to positive clinical results in 10 out of 15 affected horses.
• Therefore, in clinical practice, it’s advised to include ‘synoviocoele’ in the list of differential diagnoses for fluid-filled cavities associated with the tarsal sheath. Clinicians are also advised to contemplate endoscopic surgery as a viable treatment method.
