Percutaneous Forefoot Decompression in a Foot Compartment Syndrome Model

Area of Science:

• Orthopedic Surgery
• Trauma Care
• Anatomy

Background:

• Acute compartment syndrome of the foot presents treatment challenges due to large incisions and debated efficacy.
• Advancements in sensor technology offer new insights into foot compartment syndrome.
• Percutaneous decompression is explored as a less invasive treatment alternative.

Purpose of the Study:

• To evaluate the efficacy of percutaneous decompression for treating compartment syndrome in a human cadaveric forefoot model.
• To establish reliable methods for pressure monitoring and compartment release in the foot.

Main Methods:

• Utilized human cadaveric feet with a validated continuous pressure sensor to model compartment syndrome.
• Induce compartment pressure using a pressure-controlled saline solution infusion system.
• Investigated a novel percutaneous forefoot release technique for decompression efficacy.

Main Results:

• Successfully monitored compartment pressures continuously in all cadaveric specimens.
• Identified 4 discrete, reliably pressurable compartment areas in the foot.
• Percutaneous decompression significantly decreased pressure in all 4 compartments (average post-release pressure: 9.5 ± 3.6 mm Hg).

Conclusions:

• Established 4 consistent foot compartments using continuous pressure monitoring.
• Demonstrated successful decompression of all 4 compartments via 2 small dorsal incisions.
• Percutaneous release avoided injury to critical structures, supporting its potential clinical application.
