Outcomes of patients with single-bone-forearm surgery: a clinical assessment and three-dimensional motion analysis.
The creation of a single-bone-forearm is a salvage procedure to stabilize the forearm. The purpose of this study was to investigate clinical outcomes and how these patients compensate for the lack of forearm rotation. We evaluated four patients (three children, one adult) who had undergone single-bone-forearm surgery. Patients were examined clinically and with three-dimensional motion analysis. We found these patients are generally capable to perform important activities of daily living (e.g. glass jug pouring), which would normally need forearm rotation. Motion analysis revealed remarkable compensatory motion at other joints during these activities. We conclude that patients with a single-bone-forearm can maintain a certain level of daily activities by using compensatory motions at other joints, although the time needed to complete the tasks may be longer. Level of evidence: IV.
