Brief summary
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.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Functional result of elbow (objective) | 1 year post-op | Assess function of patients' affected elbow by MEPS (Mayo elbow performance score) |
| Functional result of elbow (subjective) | 1 year post-op | Assess function of patients' affected elbow by and DASH (Disabilities of arm, shoulder and hand) |
| Range of motion of elbow | 1 year post-op | Measure and record the ROM of the affected elbow，including flexion, extension, pronation and supination degree. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Complication: failure of internal fixation | 1 year post-op | Record whether the patients have gone through internal fixation failure |
| Complication: post-traumatic arthritis | 1 year post-op | Record if the patients have developed into post-traumatic arthritis, if any, record the degree. |
| Complication: infection | 1 year post-op | Record patients' information about infection if any, including superficial and deep infection. |
| severity of pain | 1 year post-op | Assess severity of pain by VAS (Visual analogue scale) |
| nounion | 1 year post-op | Record if there is nonunion of the olecranon (evaluated by X-ray or CT scan) |
| severity of ulnar nerve injury | 1 year post-op | Assess and record severity of ulnar nerve injury (paralysis or weakness of intrinsic muscle of hand or parathesia of ring and little finger) |
| Complication:stiffness | 1 year post-op | Record whether the patients had elbow stiffness (ROM\<100° or arthrolysis having been performed) |
| Complication: internal fixation irritation | 1 year post-op | Record whether there were internal fixation irritations |
