METHODS : Case report.
BACKGROUND : Radial nerve injury can cause severe functional impairment due to paralysis of wrist and digit extensors. Various orthotic designs have been described, including static, dynamic, and tenodesis. All provide wrist stabilization or extension assistance. Some, but not all, also provide extension assistance to the wrist, thumb, and fingers.
OBJECTIVE : This article tells the story of Max, a 27-year-old male university student, who sustained a radial nerve injury after a left humeral shaft fracture. He was treated at a Brazilian tertiary hospital, where the choice of thermoplastics and dynamic components resulted in limited options for orthotic fabrication. Max was provided with custom-molded static wrist orthosis and a bulky, older style, high-profile dynamic forearm-based wrist-finger-thumb assistive-extension orthosis.
CONCLUSIONS : Grip strength and functional status improved, and Max was completely satisfied because with the dynamic orthosis, he could play the guitar again, which was his favorite activity.
CONCLUSIONS : Max's story illustrates that a convenient functionally oriented orthotic intervention can be performed even in resource-limited environments by following the client-centered bio-occupational orthotic framework proposed by McKee and Rivard. This framework addresses the client's biological needs (addressing paralyzed muscles and maintaining length of soft tissues) and occupational/functional needs.
