We suggest that, after an initial course of treatment in the accepted manner by gentle manipulations without anaesthetic, followed by splinting for a period of three or four months, the talo-calcaneal index should be measured on radiographs taken in the standard positions described.

Should the correction be inadequate–that is, should the talo-calcaneal index be under 40 degrees even though clinically the foot appears corrected–further treatment should immediately be undertaken.

1. Experimental radiological and mechanical studies on a cadaveric cervical spine are reported.

2. A series of fifty-nine dislocations and fracture-dislocations of the cervical spine is reviewed.

3. The methods of reduction and indications for operation are discussed.
