A study of the two cases of tuberculosis of the shoulder joint in children, treated by the Jones extra-articular arthrodesis, yields the following conclusions:
1. The operation is well adapted for fusing a tuberculous shoulder in a child and gives firm bony ankylosis with little reaction on the part of the patient.
2. Bony fusion is speedily accomplished.
3. The operation should be done when the process is quiescent.
4. The cosmetic and functional results following the operation are good.
5. The epiphyses of the bones involved are not destroyed by the operation.
6. To date there has been no recurrence of the symptoms in the two shoulders operated upon by this method.
