Humeral intercondylar fractures are very challenging in clinical treatment. There are many problems not clear. One of the important problems remained to be solved is which fixation method can achieve the best effects after olecranon osteotomy. Therefore, the investigators are going to perform a retrospective analysis of patients with distal humerus fractures admitted to their hospital in 2012-2017 to compare the functional outcomes of elbow joints with tension-band fixation and plate fixation after olecranon osteotomy.
Humeral intercondylar fractures are very challenging in clinical treatment. Because the humeral intercondylar fracture is comminuted and often occurs in elderly patients with osteoporosis, it is difficult to achieve rigid fixation during the operation and failure of fixation occurs from time to time after the operation. Nonunion and reoperation have brought great sufferings to the patients.In recent years, both surgical methods and technique of internal fixation have been greatly improved, but there are still many problems not clear. Olecranon osteotomy has been proven to be an effective approach for comminuted intercondylar fractures and there are different fixation methods to fix the proximal ulna after intercondylar fixation. However, it is not clear which method can achieve the best effects. Therefore, the investigators are going to perform a retrospective analysis of patients with distal humerus fractures admitted to their hospital in 2012-2017 to compare the functional outcomes of elbow joints with tension-band fixation and plate fixation after olecranon osteotomy.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Tension-band Fixation Group | Patients with distal humerus fractures admitted to our hospital in 2012-2017 who had been performed open reduction and internal fixation through olecranon osteotomy approach were selected. All patients were devided into two groups by different fixation method. Patients who had been performed tension-band fixation after olecranon osteotomy were classified into Tension-band Fixation Group. | ||
| Plate Fixation Group | Patients with distal humerus fractures admitted to our hospital in 2012-2017 who had been performed open reduction and internal fixation through olecranon osteotomy approach were selected. All patients were devided into two groups by different fixation method. Patients who had been performed plate fixation after olecranon osteotomy were classified into Plate Fixation Group. |
