Equine articular synovial cysts: 16 cases.

This research article examines the clinical findings, diagnosis, treatments, and outcomes relating to horses diagnosed with articular synovial cysts.

Article Breakdown

The paper is a retrospective case study that explores instances where horses developed articular synovial cysts and how these cases were treated. The study spanned over two decades, from 1988 to 2009, and was conducted at two different veterinary teaching hospitals.

Clinical Findings and Diagnosis

• The study examined 16 horses that were diagnosed with articular synovial cysts.
• Most horses (9 out of 16) were referred for treatment because of lameness, a difficulty or reluctance to move that is typically associated with these cysts.
• Diagnosis was carried out using palpation and various imaging studies, which included radiography, ultrasonography and/or arthrography. These techniques helped in identifying the cysts.

Treatment and Outcomes

• Out of the 16 horses, the cyst was excised, or surgically removed, in 8 horses.
• The study had outcome data for 6 horses: 4 had their cysts surgically removed, while 2 underwent conservative treatment.
• Lameness was resolved in 3 of the horses that underwent surgery. The fourth horse, which also had surgery, unfortunately died due to unrelated causes.
• The 2 horses that received conservative treatment performed satisfactorily for the remainder of their careers. This suggests that even without surgical intervention, studying the condition and finding appropriate treatments can still help horses lead healthy lives.

Conclusions

• The researchers concluded that equine articular synovial cysts, though rare, can cause lameness in horses.
• All of the cysts studied had a synovial lining, a layer of soft tissue that lubricates and protects joints.
• Surgical excision can successfully resolve lameness and allow affected horses to return to work. This highlights the importance of early detection and intervention in managing this condition.
