The AO triangular external fixator: a backup option in the treatment of ankle fractures in geriatric patients?

Treatment strategies for complex ankle fractures-current developments summarized in a narrative review

Background and Objective

Ankle fractures occur frequently in patients throughout all ages. Due to the many pitfalls associated with their treatment, complex ankle and especially tibial pilon fractures remain a challenge for surgeons. As there is still need for improvement in treating complex ankle fractures and treatment options are steadily increasing this review aims to summarize current practice and aims to highlight current developments by reviewing the literature.

Methods

We conducted a thorough search of PubMed database in December 2022 to identify relevant articles on complex ankle and tibial pilon fractures. Articles in English and German were included in this study.

Key Contents and Findings

Complication rates, especially wound infection are still high, emphasizing the need for careful preoperative planning. Soft tissue management is crucial to reduce complication rates and will often dictate the treatment plan utilized. Open reduction and internal fixation (ORIF) remains the treatment of choice. Nevertheless, in select cases alternative methods such as external fixation, tibiotalocalcaneal nailing or conservative treatment need to be considered as well. Furthermore, additional treatment options such as arthroscopically assisted surgery might help to improve functional outcome after complex ankle fractures. The incidence of complex ankle fractures in geriatric patients keeps rising with our aging population. This group of patients demands particular care and further high-quality studies are needed to warrant best results.

Conclusions

However, more randomized controlled trials are need in order to enhance evidence of newly developed treatment options.

Ankle fractures of the geriatric patient: a narrative review

The present narrative review provides a summary of current concepts for the treatment of ankle fractures in elderly patients. Despite a high complication rate, open reduction and internal fixation is the gold standard for operative care. However, individual patient-based treatment decision considering the soft-tissue status, the fracture pattern, as well as the patient's mobility and comorbidities is mandatory to achieve sufficient patient outcomes. Due to high complication rates after surgery in the past, techniques such as fibular nails or minimal invasive techniques should be considered.

Free Flap Reconstruction of the Extremities in Patients Who are ≥65 Years Old: A Single-Center Retrospective 1-to-1 Matched Analysis

Purpose

Demographic changes are leading to population aging, and free flap reconstructions for various indications are expected to become increasingly common among older patients. Therefore, this study evaluated free flap reconstruction of the extremities in older patients and compared the outcomes to those from younger patients who underwent similar procedures during the same period.

Patients and Methods

This single-center retrospective study used a case-control design to compare older and younger patients who underwent free flap reconstruction of soft tissue defects in the extremities. One-to-one matching was performed for older patients (≥65 years) and younger patients (≤64 years) according to indication, flap recipient site, and flap type. The parameters of interest were clinico-demographic characteristics, flap type, defect location, indication for free flap reconstruction, number of venous anastomoses, and postoperative complications (flap loss, infection, and wound healing disorders).

Results

The study included 48 older patients and 133 younger patients, with a mean follow-up of 12 months after discharge. The free flap reconstruction was performed at a mean interval of 19.8±22.8 days (range: 0–88 days). The 1:1 matching created 38 pairs of patients, which revealed no significant differences in the rates of flap necrosis and flap failure.

Conclusion

This study failed to detect a significant age-related difference in the flap necrosis rate after free flap reconstruction of extremity defects. Therefore, with careful perioperative management and patient selection, microsurgical free flap reconstruction is a feasible option for older patients.
