Sixty patients under the age of twenty with sixty-seven amputations of the upper extremities have been seen in the Clinic in the past three years. Prostheses have been prescribed and fitted for forty-three, and these patients have received adequate training in the use of the prosthesis. For nine other patients, prostheses have been prescribed and ordered, but they have not yet been received from the manufacturer. Some patients are still too young, being under twenty-two months of age, for a prosthesis. This series does not include patients with partial amputation of the fingers, or those children who have only two digits which could be surgically treated by opposing one to act as a thumb.
