In reviewing the literature of the past ten years on carpal injuries we have been unable to find a reference to any case in which a fragment of the navicular bone and the entire lunate were dislocated into the volar surface of the lower third of the forearm.
In order to permit such a displacement between the flexor tendons, the annular ligament of the wrist must have been torn.
This case is being reported because the bones were dislocated so far from their normal position and because the end result of carpalectomy was excellent.
W. L., a Negro girl, aged 17 years, admitted to the Cook County Hospital, March 12, 1933, was in a condition of serious shock. While washing windows, she fell out of a fourth story window, landing in a cement courtyard.
The injuries are enumerated as follows:
Basal skull fracture with bilateral ecchymosis of the orbits
