Resection of the common digital extensor tendon in a gelding.

This research paper presents the case of a four-year-old gelding (male horse) suffering from chronic infectious inflammation of the common digital extensor tendon and its surrounding protective sheath. To treat the condition, the affected part of the tendon was surgically removed and the synovial lining of the sheath was ablated. Following the procedure, the horse was able to regain normal limb function.

Background and Clinical Examination

• The study was conducted on a four-year-old male horse (a gelding) that was presented with persistent lameness or difficulty in moving due to an infection of the common digital extensor tendon and its sheath.
• Earlier attempts to treat the infection through open surgical lavage, a procedure which cleanses the wound with a therapeutic fluid, were unsuccessful as the infection recurred after three months.

Diagnosis

• The diagnosis of chronic septic tenosynovitis and tendonitis, which refers to long-term, infectious inflammation of the tendon and the lining of the tendon sheath, was determined and confirmed through a range of tests. These included physical examination, ultrasonography (an imaging technique that uses high-frequency sound waves), cytological (cell-level) analysis, and histological (tissue-level) analysis.

Treatment

• In order to treat the condition, a surgery was performed under general anesthesia in which the entire intrathecal component (the part located within a sheath) of the common digital extensor tendon was removed or resected.
• Furthermore, the synovial lining of the sheath was ablated, which means it was surgically removed or destroyed to prevent the recurrence of the infection.

Postoperative Outcome

• Following the surgical procedures, the horse was able to recover and regain good limb function.
• The successful postoperative outcome was marked by the horse becoming sound, signifying the absence of lameness or difficulty in moving after the treatment.
