joint prosthesis

the principal example in veterinary surgery is total hip replacement.

ocular prosthesis

is used infrequently in animals. It may be fitted in the orbit after enucleation (intraorbital), within the sclera after evisceration of the defective globe (intrascleral), or over the surface of a deformed globe (extrascleral).

skeletal prosthesis

not much used in animals, largely because of the great variability in the sizes needed and the small volume required. Human prostheses have been adapted for use in primates.

urethral prosthesis

metal or synthetic conduits may be implanted in the treatment of urethral stricture and obstruction in male cats.
