The talus has some important anatomic features. Approximately 60% of its surface is cartilage and the talus often has problems with circulation. Talar neck fracture have a high association with osteonecosis and osteoarthritis. Authors have analysed 16 cases of the talar neck fractures treated at Lee-Rha General Hospital from January 1990 to December 1995 with minimal 1 year follow up.
The results were as follows;
1. In the 16 cases, there were 14 males and 2 females, the age between 20 and 40 years old was 10 cases(63%).
2. The most common rause of injury was traffic accident(63%), with sudden hyperextension as its mechanism.
3. Associated injuries were 4 malleolar fracutres, 3 calcaneous fractures, 3 spine fractures, 3 tibiofibular fractures and 2 femur fractures.
4. According to the Hawkins classification ; 3 cases in type 1, 4 cases in type II, 5 cases in typeIII, 4 case in type IV fractures were observed.
5. The method of treatment, all 3 cases of Hawkins type I fractures were treated by closed reduction and cast immobilization, 3 cases of Hawkins type II and 1 case of Hawtins type III fracture were treated by closed reduction and internal fixation, other 9 cases were treated by open reduction and internal fixation.
6. Excellent results were observed in 8 cases, good in 5 cases, fair in 2 cases, poor in 1 case with the Hawkinstherapeutic criteria.
7. Complications were observed 3 avascular necrosis, 2 post-traumatic arthritis, 2 ankle stiffness and 1 skin necrosis.
From the above results, authors believe that early anatomical reduction & internal fixation is importent to get a satisfactory result in the treatment of tatar neck fracture.
