Although the actual incidence is unknown, the problem of bicycle spoke injuries involving children is one commonly encountered both in private offices and in hospital emergency rooms. The child who rides as a passenger on a "bicycle built for one" all too frequently entangles a foot between the frame and the spokes of a wheel. As part of an injury surveillance survey sponsored by the Food and Drug Administration, our research group at Children's Memorial Hospital in Chicago has observed 12 such injuries during the period June through November, 1970, and we have supplemented our own data with two cases reported by private physicians in our area.
