“…Transformation of a fibrocyte to a chondrocyte allows longer survival time of the fibrocyte as a chondrocyte in an environment with lower oxygen tension. This is a common finding in histological examination of specimens from chronically injured tendons and ligaments in athletic horses (Martinelli and Pool 2018). In the human parapatellar fat pad, trauma and cytokines are theorised to transform mesenchymal progenitor cells into chondrocytes and osteoblasts and form a chondro‐osseous body within the fat pad (Zhang et al 2012).…”

Summary A 7‐year‐old Holsteiner gelding was presented with a left common digital extensor sheath effusion of one‐year's duration. Radiographic examination revealed two extra‐articular mineralised bodies adjacent to the dorsolateral carpometacarpal joint. Ultrasonography confirmed an intrathecal location of one mineralised body in the common digital extensor sheath, palmar fraying of the common digital extensor tendon and tenosynovitis. Ultrasound could not confirm whether the second mineralised body was intrathecal or located external to the common digital extensor sheath. Common digital extensor tenoscopy facilitated removal of both mineralised bodies and revealed a fistula communicating with the carpometacarpal joint. The mineralised bodies, initially thought to be synovial osteochondromas, were histologically identified as para‐articular osteochondromas. There are no previously published reports of para‐articular chondroma/osteochondroma in the horse. Despite surgical removal of the para‐articular osteochondromas, concern for future extensor sheath distension remained given the communication between the carpometacarpal joint and common digital extensor sheath.
