Surgical treatment of T and Y fractures of the distal humerus.

Intercondylar T and Y fractures of the distal humerus in adults present a challenge. Open reduction and internal fixation in 19 cases over a 7-year period gave excellent or good results in 15 cases. Campbell's posterior approach to the elbow joint gave a satisfactory exposure. Anterior transposition of the ulnar nerve is a very useful adjunct to prevent late neuritis. A new method of classification is suggested, taking into account the importance of the supracondylar ridge for adequate stability.
