PART IV. DISLOCATIONS.
Definition, varieties, causes, and general symptoms of dislocation. Dislocations of special joints : L Dislocations of the jaw: Differential diagnosis between the unilat- eral dislocation and bilateral dislocation, Unilateral dislocation and congenital dis.’ location, Dislocation of jaw and chronic rheumatic arthritis of the tempero-maxil- lary articulation. II. Dislocations of the shoulder : Classification of the varieties. Differential diagnoses between “+ Sub-glenoid " dislocation and fracture of neck of humerus, ‘‘Sub-clavicular” dislocation and “‘sub-spinous" dislocation, “Sub spinous” dislocation and separation of the great tubercle of the humerus, “*Sub- coracoid” dislocation and ‘‘ supra-coracoid” dislocation. Comparative table of the three more important dislocations of the humerus at the shoulder joint. Disloca- tions of the clavicle. Varieties and etiology. Subluxation of outer end of clavicle (dislocation of scapula). III. Dislocations at the elbow joint : Classification of. Dif- ferential diagnoses between both bones of forearm backwards and fracture of humerus above the condyles, Both bones of forearm backwards and radius for- wards, and ulna backwards, Both bones of forearm backwards and both bones of forearm forwards, Both bones of forearm backwards and ulna alone backwards, Radius forwards and radius backwards, Ulna forwards and ulna backwards. Com- parative table of the dislocations of both bones of the forearm at the elbow joint. IV. Dislocations at the wrist: Dislocations of the carpus, of the separate carpal bones, of the lower end of the ulna. Differential diagnoses between dislocation of the carpus and Colles’ fracture, Dislocation of the carpus and sprain of the wrist joint, Dislocation of the carpus and transverse fracture of both bones close to the wrist joint, Dislocation of the carpus and separation of the epiphyses of radius and ulna. Symptoms of dislocation of the lower end of the ulna forwards and back- wards, and of dislocation of the os magnum. V. Dislocations at the hip joint - Varieties of dislocation of the upper end of the femur. Differential diagnoses between ‘dorsum ili” dislocation and ‘‘sciatic notch” dislocation, ‘‘Sciati notch " dislocation and fracture of the femur with inversion of the foot, ‘ Pubic dislocation and ‘‘ thyroid” dislocation, ‘‘ Pubic” dislocation and fracture of the neck of the femur, Dislocation of the hip and contusion over the trochanter. Table of contrast of the symptoms of each dislocation of the hip. VI. Dislocations at the knee joint : Varieties of dislocation of the tibia and of the patella. Symptoms of dislocation of the tibia forwards, backwards, in rotary displacement, in lateral dis- placement, Symptoms of dislocation of the patella inwards, outwards, upwards, and in rotary displacement. VII. Dislocations at the ankle joint: Varieties of dis- location of the astragalus. Symptoms of dislocation of the astragalus forwards, backwards, externally, internally, and upwards. Differential diagnosis between dislocation of the astragalus upwards and fracture of both bones of the leg, Dislo- cation at ankle and a severe sprain, Dislocation at ankle and a previous deformity associated with injury. .
