The FlexiOH Full Arm is a light-cured polymer immobiliser spanning hand to upper arm, for injuries where forearm rotation genuinely needs controlling: proximal and mid-shaft forearm fractures, injuries involving the elbow, and post-operative immobilisation where pronation and supination must be prevented.
That is the whole rationale for crossing the joint. An immobiliser stopping below the elbow controls the wrist; crossing it neutralises muscle forces originating above the joint and restricts forearm rotation. Where the fracture is held by preventing rotation, the extra length earns its place.
Where the injury sits distally, the published evidence does not support reaching that far. A 2023 meta-analysis of nine randomised trials covering over a thousand children with displaced distal forearm fractures favoured below-elbow treatment on both loss of reduction and re-manipulation, without a higher complication rate, and concluded that the accumulated evidence does not support above-elbow treatment for that indication. Adult comparisons for manipulated distal radius fractures found the two approaches comparable. More coverage is not more safety, and a department stocking both lengths should be clear about which case gets which.
The open lattice serves the same purpose it does on any length: skin stays reachable, washable and inspectable through what may be several weeks, which matters more across a whole arm than a forearm. The integrated zip means emergency removal needs no cast saw.
