Displaced unstable fractures of the proximal humerus may result in pain as well as in delay of union, both contributing to prolonged immobilization and unsatisfactory results. Therfore, we must consider operative treatment for these fracture,
When
surgery is attempted, however, major4 technical problems may be encountered precluding stable fixation allowig early motion. Authors have attempted various methods of fixation for displaced proximal humeral fractures and compared the pitfalls and
compared the pitfalls and complications related to the each methods of fixatin.
@ES The following results were obtained.
1. According to Neer classification, three-part fracture (45.8%) was the commonest type.
2. Two-part fractures were treated mainly by colsed method ad fractures of three part or more, by open reduction.
3. postoperative immobilization period was shortest (mean: 9 days) in thegroup os rigid fixationwith a plate and screws.
4. Overall clinical result according to Neer criteria as excellent or good in 68.5%(24 of 35 cases) : 60%(6 of 10 cases) in K-wire fexation and 50%(2 of 4 cases) in long staple fixation after closed reduction. and 55.6%)(4 of 7 cases) in K-wire &
screw
fexation and 85.7%(12 of 14 cases) in a plate & screw fexation after open reduction.
5. The commonest complication was joint stiffness (6 cases) and 4 cases of these were in with K-wire fexation after closed reduction. and redisplacement developed in 4 cases in colsed reduction & K-wire or long staple fexation. And 2 cases of
nonunion
developed.
