What Researchers Did
Researchers presented two case reports of patients with displaced talar neck fractures who received hyperbaric oxygen therapy after delayed surgical treatment.
What They Found
Both patients, who had displaced talar neck fractures and delayed surgical treatment, received hyperbaric oxygen therapy (HBOT). Neither of the two patients developed avascular necrosis (AVN) of the talus during a three-year follow-up period.
What This Means for Canadian Patients
Hyperbaric oxygen therapy (HBOT) could potentially offer Canadian patients with displaced talar neck fractures a way to reduce the high risk of avascular necrosis, particularly if surgery is delayed. This approach might help preserve ankle and subtalar joint function and prevent the need for more invasive procedures like hindfoot arthrodesis.
Canadian Relevance
This study has no direct Canadian connection as it was conducted elsewhere.
Study Limitations
The primary limitation of this study is its design as a dual case report, which provides a very low level of evidence and cannot establish causality.
