title: Fragility fractures of the ankle in the elderly: Open reduction and internal fixation versus tibio-talo-calcaneal nailing: Short-term results of a prospective randomized-controlled study.
abstract: BACKGROUND
  The management of ankle fractures in the elderly remains unpredictable, secondary to their various co-morbidities. Although tibiotalocalcaneal (TTC) nailing has been an effective option for ankle arthrodesis due to ankle arthritis or Charcot arthropathy there are few reports regarding the use of TTC nail for the treatment of ankle fractures.
  
  
  OBJECTIVE
  Aim of this study was to compare the results of ORIF versus TTC nailing for the treatment of unstable ankle fractures in the elderly. We hypothesized that the elderly may benefit from TTC nailing, as it allows the patient to be mobilized immediately after surgery and minimizes the risk of wound or bone problems.
  
  
  METHODS
  This was a prospective, randomized-controlled, comparative study. Between 2009 and 2015, 43 patients were treated with a TTC nail (Group A) and 44 with ORIF (Group B). The Olerud-Molander ankle score was obtained and intraoperative-postoperative complications, length of hospital stay, mobility status and reoperation rate were recorded. The nail fixation was performed with the TrigenR hindfoot nail after closed reduction. ORIF was performed, using a 1/3 tubular plate and 3.5mm screws for the lateral malleolus and two 4.0 mm cannulated screws for the medial.
  
  
  RESULTS
  Mortality rate at one year was 13.9% for Group A and 18.1% for Group B. Mean follow-up was 14 months (12-18m). There were no intraoperative complications. Three complications in Group A (8.1%) and twelve (33.3%) in Group B were encountered postoperatively (p<0.05). There was significant shorter hospital stay in Group A (5.2±3.1d) than in Group B (8.4±5.2d). In Group A, 28 patients returned to their pre-injury mobility status (75.6%) while 9 declined one level of the mobility scale (24.3%). In Group B, 26 patients remained at the same mobility level (72.2%) and 10 declined one level (27.7%). There was no significant difference between the postoperative OMAS scores in the two Groups (56.9±9.85 and 56.6±9.3 respectively).
  
  
  CONCLUSIONS
  We believe that TTC nailing is a safe and effective method of treatment of unstable ankle fractures in the elderly because it has a low risk of complications and restores function and mobility allowing an immediate return to full weight-bearing.
