Posterior malleolar fracture: technique and clinical experience of the posterolateral approach.
OBJECTIVE
To introduce the postero- lateral surgical approach to the posterior malleolar fracture and report its clinical outcomes in 32 cases.


METHODS
This study consisted of 32 cases, 22 males and 10 females with the mean age of 48 years (range, 21-63 years), suffering from posterior malleolar fracture. All cases were treated with the posterolateral surgical approach to the ankle. The average follow-up period was 28 months (range, 24-35 months). The clinical outcomes of these cases were evaluated on the basis of the Olerud-Molander Ankle (OMA) score and plain radiographs.


RESULTS
All cases showed radiological evidence of bony union at follow-up. The average OMA score was 82 points; 21 cases had excellent scores (90-100 points), 9 good (61-90 points), and 2 fair (31-60 points). The excellent-to-good rate was 93.8%. Although most cases did not show any wound dehiscence or necrosis, one patient had a superficial infection which healed after using antibiotic dressing and one had sural cutaneous nerve injury that underwent spontaneous remission without any treatment after three months. In addition, one presented with mild symptoms of peroneal tendonitis that disappeared after plate removal.


CONCLUSIONS
The posterolateral approach offers an effective technique for fracture reduction and fixation of large posterior malleolar fragments.
