1. Most supracondylar 'T' fractures of the humerus do not require open reduction.
2. When open reduction is required, the posterior operative approach which has been illustrated is considered to be the best.
3. No other approach known to the writer affords so adequate an exposure of the fracture area, allows so great a freedom in the selection of fixation materials, does so little harm to important anatomical structures, or offers such an excellent view of the articulating surfaces.
4. The so-called 'split-triceps approach' is not considered by the writer adequate for this type of fracture and should not be confused with the approach which he has described.
5. Operative treatment of these fractures is a serious major procedure, not without danger, and preliminary planning and preparation of fixation materials are essential for success.
6. Eight cases of supracondylar 'T' fractures of the humerus have been treated by the operative procedure described, and their end results are illustrated. No cases have been omitted.
7. Of these eight cases, the end results may be considered as excellent in five; as a complete failure in one; and as poor in two. With proper care, the 'poor' results in the latter two cases could have been avoided.
