Customized dynamic splinting: orthoses that promote optimal function and recovery after radial nerve injury: a case...

Radial nerve injury is a relatively common occurrence and recovery depends on the level of injury and extent of connective tissue damage. Orthoses (splints) are often provided to compensate for lost motor power. This article chronicles the recovery, over 27 months, of a 76-year-old woman who sustained a high radial nerve injury of her dominant arm during surgery for total shoulder replacement (Delta Reverse). Customized, low-profile dynamic splints, unlike any previously published design, were developed to address her goals for functional independence and the biological needs of the tissues. Dynamic power was provided to the wrist, fingers, and thumb by elastic cords and thin, flexible thermoplastic, without the need of an outrigger, thus avoiding the need for wire bending and cutting. At the outset, the splint was forearm-based and when wrist extension power was recovered, a hand-based splint was designed. Eventually, a circumferential hand-based thumb-stabilizing splint fulfilled most of the remaining orthotic requirements.
