abstract
Forearm compartment syndrome threatens life and limb. The treatment is fasciotomy without delay, yet the standard surgical approaches do not address access to the deep compartments. If the deep space is not explored, contracture and/or necrosis may occur, with devastating results. Indications for...
evaluation of the deep space include electrical injuries, severe crush injuries, positional compression in comatose patients, and failed previous superficial fasciotomy. Deep fasciotomy often involves blunt, blind dissection, which places vascular pedicles and motor branches at risk for injury. Surgical disruption may contribute to ischemia and edema, adding to any injury already caused by the elevated tissue pressures.
reason, objective, purpose
The goal of this study was to assess the ability of different surgical approaches to visualize the deep muscles without iatrogenic injury to the muscles, arteries, and nerves.
materials used
Detailed anatomical analysis of 10 cadaver arms, two of which were injected with silicone and mildly plastinated. Findings were corroborated by live magnetic resonance angiography using a 3D fast spoiled-gradient echo technique that showed small vessels entering muscle. Three standard surgical approaches to the deep forearm were evaluated on each cadaver: radial (modified Henry and Spinner approach), central, and ulnar (modified McConnell approach). Iatrogenic injury to muscle, arteries, and nerves was evaluated on a scale of 1 – 3 (best – worst) for each category. Muscle injury was graded according to whether no dissection, sharp dissection, or division of the muscle was required for access to the deep space. Arterial injury was graded according to the number of segmental branches or dominant pedicles that required division. Nerve injury was graded similarly. The lowest possible score, corresponding to the safest approach, was 3. The highest possible score, corresponding to the most injurious approach, was 9. A Mann-Whitney Wilcoxon test for non-parametric data was used to analyze the data.
