The camel was affected with rickets and the aurochs had multiple exostoses or bony tumors.
Large exostoses had developed and the subject remained lame, but union of the broken bone took place in a surprisingly prompt and effective manner, when age of the subject and nature of the fracture are considered. As a rule, one is loath to recommend treatment, even in a simple transverse fracture of the first phalanx, in animals ten years of age or older.
A remarkable form of unilateral hypertrophy and diffuse osteoma of the skull, following the distribution of the fifth nerve, has seen described by Jonathan Hutchinson and Alexis Thomson. #Chondroma.# Cartilaginous tumours, apart from those giving rise to multiple exostoses, grow from the long bones and from the scapula, ilium, ribs, or jaws.
If lameness is due to acute inflammation bad results such as sloughing and loss of the hoof may follow; and if large exostoses mechanically interfere with function of the joint, or where articular erosions exist, no possible good can come from neurectomy.
