Newell, RL.


1. A coccygeal sinus must be regarded as due to a defect in embryonic development. It probably is the result of traction on the skin caused by retrogression of the tail bud.

2. The treatment consists in the removal of the whole of the sinus together with that portion of the median raphe which contains the origin of the condition.

3. The extent of the sinus may be difficult to recognize without a lipiodol injection, followed by an X-ray examination.

4. The dissection is rendered easier by an injection of paraffin wax immediately prior to operation.
