![The total number of cases on the records was 453, of which 420 were traumatic, 100 females, 290 males, and 23 were congenital; of the latter, 18 were of the hip, 15 females, 3 males, 2 each of the elbow and patella, and 1 of the knee. During the same period 2958 fractures were treated, a proportion of 7 to 1, reckoning the traumatic dislocations alone. The following table has been made by combining Kronlein's statistics with a compilation made by Prahl of- his own and others to show the direction in which the inclusion of dispensary or polyclinic statistics alTects the percentages.

Each set of statis- tics shows that dislocation of the shoulder is far more common than that of any other joint, the percentages varying from 45.2 to 60.7 ; that next in frequency come dislocations of the elbow, Avith percentages varying from 10 to 27.2. These two dislocations may be estimated as together comprising from two-thirds to three-fourths of all cases; of the remaining one-third or one-fourth, dislocations of the fingers and hip form the majority. The side upon which the dislocation took place is so seldom mentioned in the records from which the statistics have been compiled that no posi-](https://iiif.wellcomecollection.org/image/b21987063_0030.jp2/full/800%2C/0/default.jpg)
