RESUMO
<p><b>OBJECTIVE</b>To compare the differences of radiographical and functional outcomes between traditional and minimally invasive approach in treating Hawskins type I fractures of the talar neck.</p><p><b>METHODS</b>From February 2000 to February 2008, 37 patients underwent reduction and internal fixation using two different approaches. In minimally invasive approach group, there were 16 males and 2 females, ranging in age from 20 to 47 years, averaged (35.2 +/- 3.1) years, and in traditional approach group, there were 15 males and 4 females, ranging in age from 22 to 44 years, averaged (35.3 +/- 2.3)years. All the patients had Hawskins type I fractures. The following data were compared between two groups: operation time, blood loss, length of incision and function of ankle joint. All the patients were graded by Hawkins points-scoring system after operation.</p><p><b>RESULTS</b>All patients were followed up. The duration ranged from 2 to 10 years, with an average of 5.6 years. The index such as operation time, blood loss and the length of incision of patients in minimally invasive approach group were significantly less than those of patients in traditional approach group. According to AOFAS points-scoring system, the score of minimally invasive group was higher than that of traditional approach group.</p><p><b>CONCLUSION</b>Compared with traditional approach, minimally invasive approach can protect blood supply better, get better clinical effects,which is worth of choosing to treat Hawskins type II fractures of talar neck.</p>
