Background: Fractures of the olecranon are a relatively common injury in adults. The present study was conducted to compare open reduction and internal fixation by tension band wiring and hook plate in olecranon fracture cases. Materials & Methods: 50 olecranon fracture cases of both genderswere divided into 2 groups of 25 each. Group I patients were treated with tension band wiring and group II patients with hook plate. Parameters such as side, mode of injury, MAYOclassification, average time taken from injury to surgical management (days), associated injury, duration of surgery, radiological union and complications was recorded. Results: There were 15 males and 10 females in group I and 12 males and 13 females in group III. In group I and II, side involved was right in 13 and 11 and left in 12 and 14. Mode of injury was sports in 2 and 5, assault in 3 and 4 and road sideaccidentin 20 and 16 respectively. MAYOclassificationIA was seen in 3 and 1, IB in 2 and 4, IIA in 12 and 11 and IIIA in 8 and 10 respectively. Average time taken from injury to surgical management was 0-1 days in 13 and 11, 1-3 days in 7 and 8 and 4-7 days in 5 and 6. Associated injury was fracture shaft of femur in 1 and 0, fracture inter trochantric femur in 2 and 1 and fracture bothbone legs in 1 and 0. Duration of surgery (min) was 40.2 and 53.6. Radiological union was 6 weeks in 4 and 6, 12 weeks in 6and 7, 18 weeks in 10and 8 and 24 weeks in 5 and 4 respectively. Complications was superficial infectionin 1 and 1, deep infection in 2 and 0 and wire migration in 1 and 1 respectively. The difference was significant (P< 0.05). Conclusion: Tension band wiring is a simple, inexpensive technique and effective means of fixing olecranon fractures.
