Which technique helps reduce hand edema after injury?

• A. Elevation and retrograde massage, with compression as appropriate.
• B. Ice therapy directly on skin for 20 minutes.
• C. Passive ROM of fingers only.
• D. Massage without elevation or compression.

Answer: (A)

Reducing hand edema after injury relies on promoting fluid return from the hand through gravity, lymphatic drainage, and external support. Elevation lowers hydrostatic pressure in the hand, helping fluid move proximally toward the forearm. Retrograde massage gently moves fluid from the distal tissues toward the proximal lymphatic channels, encouraging lymphatic drainage and venous return without pushing fluid back into damaged areas. Compression, when appropriate and tolerable, supports the tissue pressure gradient to prevent re-accumulation of fluid and aids sustained drainage. These elements work together to decrease swelling and improve hand function. Other approaches don’t target this coordinated drainage pattern as effectively: direct ice can alter circulation in ways that don’t consistently reduce edema, and motion or massage without elevation and compression offers less control over fluid movement and may not effectively lessen swelling.
