“…The most commonly reported cause of TMJ‐OA in horses and humans is trauma (He et al., 2013; Wammerdam et al., 1997). Similarly, subchondral bone cysts can be the result of developmental anomalies or trauma to the subchondral bone plate immediately underlying the articular cartilage (Jackson & Fürst, 2019). The aetiology of cyst formation in the mandibular condyles of the horse presented in this case report is unknown, especially as there was no history of trauma.…”

“…Arthroscopy has become the most specific and sensitive method of evaluating equine joints (McIlwraith et al., 2015). The management of subchondral bone cysts has resulted in many different treatment modalities over time, with the most recent being trans‐cystic screw placement (Jackson & Fürst, 2019). The progression of OA may be moderated by addressing the underlying cause, but cessation of the disease process rarely occurs.…”

“…The presence of cysts within the articular cartilage of other equine joints, notably the stifle, fetlock and distal interphalangeal joint, has been associated with osteoarthritis (OA) and lameness (Jackson & F€ urst, 2019). In contrast to this, OA of the TMJ (TMJ-OA), other than that which develops secondary to sepsis, is rarely reported (Smyth et al, 2017;Stadtb€ aumer & Boening, 2002).…”

Summary A horse was presented with a history of unpredictable behaviour under saddle to the point that the owner deemed the horse dangerous to ride. In addition, at rest the horse frequently protruded his tongue and during mastication a “clunking” sound could be heard. Radiographic examination at a previous clinic had revealed a normal left temporomandibular joint (TMJ) and a radiopaque mass in the right TMJ. However, despite arthroscopic surgery of the abnormal joint, the clinical signs had not resolved. Diagnostic investigation at the referral clinic revealed that TMJ analgaesia altered both a baseline hindlimb lameness and a behavioural component to the movement of the horse. Computed tomography (CT) illustrated the presence of bone cysts within the mandibular condyles and marginal osteophytosis of the discomandibular joints consistent with osteoarthritis. Arthroscopic examination, debridement of the affected joints and post‐operative intra‐articular injection of autologous protein solution resulted in temporary resolution of both the behavioural changes and the “clunking” sound. Ultimately, the horse was euthanised for continued dangerous behaviour, which treatment had failed to resolve in the longer term. In conclusion, the presence of cysts in the mandibular condyle and osteoarthritis can be a cause of abnormal behaviour, which may render a horse dangerous to ride. The case report illustrates the complex interaction between the TMJ, behaviour and movement.

“…Die postoperative Behandlung und Rekonvaleszenzzeit nach einer arthroskopischen oder transkortikalen Behandlung der SCL, inkl. der transzystären Schraube, entsprechen in etwa denen anderer arthroskopischer Therapien und können dem Schweregrad der Läsion angepasst werden 29 . Die Pferde sollten für einige Tage Schmerzmittel und 2 – 4 Wochen Boxenruhe erhalten.…”

“…Eine intraartikuläre Anästhesie kann die klinische Bedeutung der SCL bestätigen [6,27], jedoch auch variable und unvollständige Ergebnisse liefern [28]. Sie ist oft positiv, wenn eine Verbindung ins Gelenk besteht [29]. Negative Ergebnisse der intraartikulären Anästhesie sind dagegen am ehesten mit einer inkompletten Absorption des Lokalanästhetikums in den subchondralen Knochen zu erklären [27].…”
