Intractable slipping at the temporomandibular articulation may be due either to a lesion of the interarticular fibrocartilage-corresponding to a lesion of the internal meniscus of the knee-or to an actual dislocation of the condyle which slips forward over the eminentia articularis. The former group can be cured by the simple removal of the meniscus. For curing the latter group, a new operation is described, consisting in the construction of a bone block just anterior to the eminentia articularis. Four cases of cure are cited,-one of the first group, three of the second.
