External fixation of unstable fractures of the distal radius has produced satisfactory results but has some problems. We studied the indication and the limitation of the external fixation in 33 fractures of the 32 patients.
The dorso-medial fragment (so called “die pumch fragment”) was not often reduced with external fixation technique. Because the dorsal wrist ligaments are not adequate for reduction by ligamentotaxis. Percutaneous pinning or open surgical treatment are necessary for this fragment.
The failure to restore palmar tilt and ulnar variance was concerned with the prognosis. Accurate anatomical reduction is neceesary to provide the good results.
The results appeared to be independent of the type of external fixation apparatus employed (Hoffman, Ace, Clyburn).
