[Conventional X-Rays of Ankle Joint Fractures in Older Patients are Not Always Predictive]

Complications following surgical treatment of ankle fractures in the elderly: can they be avoided?

Background Following surgical treatment of ankle fractures, geriatric patients face high complication rates (CR) in literature. Commonly used diagnostic and treatment algorithms fail to consider requirements of ageing patients which increases the risk of postoperative complications. Objective Present study critically evaluated surgical management of ankle fractures in patients over 65 years old, with focus on identifying modifiable risk factors and effective comorbidity management strategies. Methods We conducted a retrospective single-center study on patients who underwent surgical treatment of an ankle fracture. Based on their age, participants were divided into non-geriatric patients (NGP<65y) and geriatric patients (GP≥65y). We analyzed overall CR and number of minor and major complications in relation to timing of surgery, biological sex, injury pattern, osteosynthesis, pre-existing medical conditions, and postoperative care. Results 402 patients were included. GP encountered significantly higher overall (p<0.001), minor (p<0.001) and major (p=0.003) complications. They presented more complex, displaced and open fractures. Predominant factor contributing to higher CR in NGP and markedly in GP was concomitant diseases, presenting a strong OR of 19,290 (p<0.001) and 17,022 (p<0.001). Delaying surgery and managing comorbidities preoperatively had a favorable impact. Conclusion We revealed a high significant correlation between pre-existing medical conditions and postoperative results. To ascertain viability of delayed surgery in facilitating additional diagnostics and treatment of comorbidities, further comparative trials with a larger cohort are imperative.

[Ankle fractures in older patients : What should we do differently?]

As a result of the demographic developments ankle fractures in older patients are part of routine trauma surgery. Due to comorbidities, such as diabetes mellitus, reduced bone quality and limited compliance in follow-up treatment, these fractures are prone to complications. The primary goal in the treatment of older patients with ankle fractures is to maintain mobility. In contrast to young patients most fractures are unstable pronation-abduction injuries. In the diagnostics the recognition and optimization of factors influencing the outcome, such as the blood perfusion and the generous use of computed tomography (CT) are recommended. As in the case of younger patients, conservative treatment is reserved for stable fracture forms and, if there are contraindications, should also be initiated in the case of unstable injuries. The choice of approaches is different for surgical treatment, which is adapted to the soft tissues, if necessary minimally invasive and increasingly carried out by a posterolateral approach. The initial transfixation can reduce soft tissue problems. Special surgical techniques and implants that provide a high level of stability, such as dorsal plate positioning, hook plates, angular stable plate systems and intramedullary systems as well as additional options, such as tibia pro fibula constructs are used. Primary retrograde nail arthrodesis is reserved as a salvage procedure only for exceptional cases. As part of the follow-up treatment, an interdisciplinary approach with respect for and optimization of concomitant diseases seems to make sense.
