Panel Discussion – Effective Treatment of Subchondral Bone Cysts (Recorded 29 September 2020)


Panelists:Elizabeth Santschi   DVM, DACVS – Kansas State University, USA
Bruce Bladon   BVM&S, CertEP, DESTS, DECVS, FRCVS – Donnington Grove Veterinary Group,
Ryland Edwards   DVM, PhD, DACVS, DACVSMR – Fairfield Equine, USA
Moderator:Anton Fürst, DECVS – University of Zurich, Switzerland


Over the past few years new information about subchondral bone cysts (SBC) has come to light. Increased use of CT and MRI diagnostics has revealed that SBC are common in the horse, occur in many different bones and locations and that trauma is an important aetiologic factor leading to development of SBC. Common treatment choices for SBC fall broadly into two categories: non-surgical (steroid injections) and surgical (drilling, screw placement or curettage ± packing). Dependent on the anatomic location and cause of SBCs, they might require different treatments.

As part of this panel discussion the following points will be debated by the panelists:

Pathophysiology & Diagnostics
•    Relevance of “dimple” lesions of the stifle & radiolucent indentations of the medial femoral condyle on pre-purchase radiographs
•    Subchondral Bone Cysts, subchondral cystic lesions or subchondral lucencies – Which terminology is most appropriate?
•    What’s the exact aetiogenesis of SBC: Genetic-OC, Trauma, others?
•    Are radiography and ultrasound sufficient to fully image SBCs or should we routinely use MRI or CT?
•    Should we treat sound horses with SBC detected on radiographs?
Treatment Options

•    Medication of bone cysts with cortisone – Effective long-term treatment or only short-term fix?
•    Should age, breed, type and level of work and type of lesion influence our treatment options (conservative vs. surgery
•    Best surgical therapy – Curetting, filling and/or screwing?  Should a screw always be placed or could drilling alone be enough?
•    Resorbable, stainless steel or titanium screws for the treatment of SBC – Which generates the best results?
•    Should stainless steel screws always be removed?
•    Does the location of the SBC influence the decision on treatment options?
•    When filling the cyst, which material is today considered the gold standard?
Prognosis / Long-Term Outcome
•    Long-term outcome comparison between conservative and surgical therapies
•    Pre-purchase exam of horses with SCBs that have been successfully treated with a screw…

    More Info

    Prof. Dr. Anton Fürst is a Diplomate of the European College of Veterinary Surgeons (ECVS) and the head of the Equine Hospital of the Vetsuisse Faculty, University of Zurich. This department offers an overall high caseload on clinical patients every year. The technical expertise and interests of Dr. Fürst cover all fields of equine surgery, and he has already performed several studies about kicking injuries, first aid and osteochondrosis in horses. Currently, his main research focuses on equine orthopaedics. In particular, he is interested in the treatment of subchondral cystic lesions (SCLs) in horses. Dr. Fürst strives for new treatment strategies to improve the healing of SCLs. Therefore he investigated the etiology and pathogenesis of SCLs and is developing new, biologically active filling materials to be injected in the cystic cavity after debridement. After in vitro characterization and proof of efficacy of new materials, the clinical caseload offers future opportunities for their clinical application.

"I find the panel discussions very helpful...areas of consensus and dissention are illuminated and the conversations make it more understandable as applied to individual cases or situations".
