Objective: The objective of this study was to develop a single-channel telemetric intramedullary nail that measures anterior-posterior bending strains and determine whether these forces decrease sigmoidally when normalized to the ground reaction force during fracture healing.
Methods: A transverse midshaft femoral osteotomy (1 mm) was stabilized using a customized TriGen intramedullary nail incorporating a strain gauge in the anterior-posterior plane. Fourteen skeletally mature sheep (2-3 years old) were treated in two pilot studies (n = 3/pilot) and a pivotal study (n = 8).
