2 DISCLAMIER My disclosure is in the Final AOFAS Program Book. I have no potential conflicts with this presentation

3 INTRODUÇÃO There is a great controversy over the better treatment of ankle fractures in patients above 60 years 1,2,3,, because the high rate of complications mainly in patients with systemic comorbidities 4,5,6 A A A OBJETIVO The purpose of this study was to evaluate the results on elderly patients with ankle fracture, operated by the augmentation technique

4 MATERIAL Period December 2006 to October patients with ankle fracture and systemic comorbidities all 44 B or C of the AO-OTA system. Age: 61 and 88 years (Median 72 years) 10 patients were diabetics type II, 8 smokers, four had kidney disease, two patients had rheumatoid arthritis and six patients were chronic users of corticosteroid.

5 MÉTODO Augmentation fixation (conventional fixation of fracture and increased syndesmosis fixation) 4, Early mobilization and released full support with 8 weeks of PO The results were evaluated as the function, complications, reoperations number (return material or additional surgeries), re-hospitalization and mortality 7,8. D D

6 RESULTADO Follow-up of 18 to 48 months (average of 28 months Six superficial infections with improved with antibiotic and others two with skin necrosis that required skin graft. None patient have lose of reduction or implant loosening that need reoperation

7 RESULTADO 8 patients were removed the screws of syndesmosis, in 5 patients were removed all the synthesis by loosening of screws. The patients age doesn t show difference on final results All patients returned to walk and their daily activities. Satisfaction: 15 (93.75%) are satisfied One was with restricted due to limitation of physical activity. Four patients need new hospitalization due to uncontrolled diabetes and all patients are alive. No patient by this time necessitated new fixing or Ankle arthrodesis C

8 A A A 1 2 CASE 3 C C NNV, 82y, 82Y, Female, FemDM DM Type Type II, II, oteoporotic osteoporotic bone 1) 1) pre-op. 2) POI.,3) 2) Skin 3) Skin Necrose Necrosis 8 w/8 weekspo. 4) Follow-up 4 8m PO 16m PO 24m PO

9 DISCUSSSÃO Osteopenic bones exhibit high rates of complications when undergoing conventional surgical techniques 1,2,8, in the pursuit of improving the stabilities of fixation of these fractures were developed fixings blocked 7, but these are not always accessible to your use, as well as features high cost, making it impossible for its use on a regular basis. The fixation with the technique of "augmentation" is presented in the literature as a low-cost and affordable option to your job, so is a stable mounting in osteopenic bone patients, slowing down the rate of complications 4.

10 DISCUSSSÃO The method of fixation of the screw of the fibula to the tibia can help improve rigidity, strength, stress, axial deformation and failure 4,7, same facts are described when the use of additional anchorages in fractures of the ankle, which was demonstrated in our cases, presented tissue necrosis exposure and/or release of synthesis material but without the loss of fracture reduction until its consolidation, which is expressed by the return of our patients to their pre-injury levels activities.

11 CONCLUSÃO The fixation of ankle fractures with the augmentation technique in patients above 60 years, bearers systemic comorbidities demonstrated safe and stable. It allows the mobilization and early weight bearing and progressive load, demonstrated by low rates of complications, as well as the patients ' satisfaction index of 93.75%.
