Endoscopic surgery

REASONS FOR PERFORMING STUDY: The overall rate of sepsis following endoscopic surgery of synovial structures has not previously been documented. Clinical observation has led to the conjecture that tendon sheaths, in particular the carpal flexor tendon sheath, are more prone to post operative synovial sepsis than other synovial structures.

OBJECTIVES: To document and investigate the rate of post operative synovial sepsis following elective endoscopic surgery.

STUDY DESIGN: Retrospective case series.

OBJECTIVE: Report long-term clinical and radiological follow-up in horses after removal of large extensor process fragments occupying >25% of the joint surface of the distal interphalangeal joint (DIJ).

STUDY DESIGN: Retrospective case series.

ANIMALS: Friesian horses (n=18) that underwent arthroscopic removal of a large extensor process fragment.

OBJECTIVE: To describe an alternative technique and resulting outcomes for arthroscopic removal of osteochondral (OC) fragments from the proximal intertarsal joint (PIJ) using a direct approach without resection of the membrane between the tarsocrural joint (TCJ) and the PIJ.

STUDY DESIGN: Retrospective case series.

ANIMALS: Client owned horses (n = 11) with Category 1 OC fragments in the PIJ.

OBJECTIVE: To describe an alternative technique and resulting outcomes for arthroscopic removal of osteochondral (OC) fragments from the proximal intertarsal joint (PIJ) using a direct approach without resection of the membrane between the tarsocrural joint (TCJ) and the PIJ.

STUDY DESIGN: Retrospective case series.

ANIMALS: Client owned horses (n = 11) with Category 1 OC fragments in the PIJ.

OBJECTIVE: To compare intra and postoperative clinical features of desmotomy of the accessory ligament of the superficial digital flexor tendon (ALSDFT) using the Saber radiofrequency (SaberRF) electrosurgical probe versus sharp transection with a tenotomy knife.

STUDY DESIGN: Randomized, controlled, blocked (horse) design.

ANIMALS: Adult horses (n = 6).

OBJECTIVE: To characterize discrete palmar carpal osteochondral fragmentation in horses and to document the effect of osteoarthritis and surgical removal of these fragments on functional outcome.

DESIGN: Retrospective case series.

ANIMALS: 25 horses.

Reasons for performing study To determine risk factors involved in survival to hospital discharge of cases of synovial sepsis. Objectives Investigate pre-, intra- and post operative factors involved in short-term survival of horses undergoing endoscopic treatment for synovial sepsis. Study design Retrospective case series. Methods Clinical data were obtained for horses (>6 months old) undergoing endoscopic surgery as part of management for synovial sepsis over a 7-year period in a single hospital population. Descriptive data were generated for pre-, intra- and post operative variables.

The aim of this study was to determine whether horses with a proximal palmar/plantar first phalangeal osteochondral fragment (POF) had comparable racing careers (prior to and following surgery) to horses without this fracture. A retrospective cohort study included 174 Swedish Standardbred trotters with osteochondral fragmentation in the palmar/plantar fetlock joint and 613 radiographically negative control horses presented for prepurchase examinations. Medical records and radiographs were examined for each horse.

Objective To describe an ultrasound assisted arthroscopic approach for removal of non-articular basilar sesamoid fragments in Thoroughbred yearlings. Animals Thoroughbred yearlings (n = 7). Methods Basilar sesamoid fragments identified during pre-sale radiographic examination were removed using a palmar/plantar arthroscopic approach to the fetlock joint and ultrasonographic guidance. Complete fragment removal was confirmed by ultrasonography and radiography.
