    (c) Dislocation of the mandible is extremely rare in cases of fracture. (d) Injury to tlie teeth. One or more teeth in the vicinity of the fracture are occasionally broken or a tooth may be dislocated from its socket and interposed between the broken ends of the bone interfering with the process of union. (e) Damage to the mandibular nerve may occur at the time of the accident, or subsequently from the pressure of callus, causing anaesthesia or neuralgia in the region supplied by the nerve. (f) Injury to the base of the skull. The condyle has been known to be driven through the glenoid cavity and inflict fatal injury to the brain. (g) Necrosis may result from complete separation of a fragment from its vascular connections at the time of the injury or subsequently as the result of suppuration. (h) Salivary fistula may result from imperfect healing of an abscess which has burst upon the surface of the cheek. (i) Vicious union, i.e., union with deformity, may occur when the fragments have not been kept in proper apposition, especially in multiple fractures, or where there has been loss of bone from necrosis. (j) Non-union may be due to want of apposition through lack of treatment, or through the interposition of a loose or necrosed fragment or a dislocated tooth. (k) False joint In this condition the ununited fragments become rounded off at the ends and held together by a sort of fibrous capsule lined by a smooth membrane which secretes a kind of synovial fluid. In Esmarch’s operation for closure of the jaws, the surgeon aims at producing this condition.
