“…Permanent resolution of signs with the chance of a future racing career was considered possible with surgical removal of the large, osteochondrotic fragment identified within the left C4-C5 APJ and removal of this fragment resolved the neck pain and clinical signs of neck stiffness in the short term. An APJ OCD fragment has been previously reported as a source of neck pain in a single horse (Beck et al 2002). In the case presented here, in addition to the bone fragment, imaging and post-mortem examination revealed further OCD lesions affecting multiple APJs.…”

“…Pathology of the APJs can cause neck pain, abnormal head carriage and forelimb lameness (Ricardi and Dyson 1993;Van Biervliet 2007;Dyson 2011) and enlarged APJs can cause dorsolateral compression of the spinal cord, contributing to cervical spondylomyelopathy (Moore et al 1994). Osteochondrosis (OCD) of the APJs has been reported (Powers et al 1986;Stewart et al 1991;Trostle et al 1993) and has been confirmed in a small number of horses at postmortem examination (Beck et al 2002;Janes et al 2015).…”

Summary A yearling Thoroughbred colt was presented for investigation of neck stiffness and episodes of intermittent neck pain without neurological signs. Osteochondrosis (OCD) of the cervical articular process joints (APJs) was diagnosed with the aid of radiography and computed tomography. An articular osteochondral fragment of the left fourth caudal cervical articular process was removed arthroscopically following a cut down approach to the joint capsule of the affected APJ. Surgical removal resulted in resolution of clinical signs at 4 weeks. However, subsequently the horse was markedly ataxic 6 weeks post surgery after being found cast in its stable. Cervical stenotic myelopathy was considered the most likely cause based on clinical and radiographic signs and the horse was subjected to euthanasia due to a poor prognosis for racing. Post‐mortem examination identified atypical cartilage within several cervical APJs with histological changes consistent with OCD. This case report supports OCD of the APJs as a cause of neck pain and confirms the clinical practicality and short‐term effectiveness of arthroscopic fragment removal. Surgical treatment for cervical OCD should be considered in horses without neurological signs, although case selection is important and the underlying pathology remains a risk factor for the development of subsequent neurological signs.
