Clinical Report: Reconstructive Approach for Frostbite in Tropical Conditions
Overview
This report details a case of severe frostbite in a 59-year-old male mountaineer, highlighting a two-stage reconstructive strategy utilizing hyperbaric oxygen therapy and an abdominal pedicled flap. The approach aimed to preserve digital length and joint function, resulting in stable, partially sensate digital stumps at ten months follow-up.
Background
Frostbite is a significant ischemic injury that can lead to severe functional impairment, particularly in the hands. While traditionally associated with cold environments, frostbite can occur in tropical regions, especially among high-altitude climbers. Effective management is crucial to prevent amputation and preserve hand function, making reconstructive strategies vital in these cases.

Follow-up
10 months
Key Findings
Severe frostbite led to dry gangrene necessitating amputation of the right hand.
Hyperbaric oxygen therapy (HBOT) was initiated to enhance tissue viability during demarcation.
A two-stage reconstructive approach was employed using an abdominal pedicled flap.
The patient achieved stable, partially sensate digital stumps with preserved length and joint motion at follow-up.
Conservative treatment of the left hand with HBOT resulted in maintenance of tissue viability.
Clinical Implications
This case illustrates the importance of a multidisciplinary approach in managing severe frostbite, particularly in tropical environments. The combination of HBOT and reconstructive surgery can significantly improve functional outcomes and preserve hand anatomy, which is critical for patient rehabilitation.
Conclusion
The successful application of a two-stage reconstructive strategy in this case underscores the potential for enhanced functional recovery in severe frostbite injuries. Continued exploration of such techniques is warranted to optimize patient outcomes.
