Abstract
|
|
|
Open reduction and internal fixation with modified tension band technique is a widely accepted method in the treatment of displaced patellar fractures.
The authors experienced 22 cases of displaced patellar fracture treated with modified tensing band internal fixation from January 1987 through January 1992 and the length of follow up was average 12.2 months.
@ES The results were as follws:
@EN Out of 22 cases, male was 16 cases(72.7%) and the average age of patient was 41.1 years.
2. The most common cause of injury was slipping down(15 cases, 68%) and the other was direct blow(7 cases, 32%).
3. Transverse fractures were 13 cases and comminuted fractures were 9 cases(We did not include vertical fractures).
4. In severely comminuted fractures(4 cases), the fragments were indirectly reduced by anterior cerclage wire passed through the soft tissues of the fragments and then fixd with two vertical Kirschner wires and figure of eight tension band wir.
5. The duration of immobilization was 2 to 4 weeks.
6. The radiological union was obtained in 6 weeks except one nonunion case.
7. There were three cases oftechnical failures. Among them one case needed further surgical treatment.
8. The nonunion cas was treated by modifed tension band internal fixation with bone graft.
The radiological union was obtained in 8 weeks after second operation.
In conclusion, tersion band internal fixation is a good method for transeverse and comminuted patellar fracures.
