Why the study?
Femoral malrotation is a common, underrecognized complication following intramedullary nailing of femoral shaft fractures that causes cosmetic and functional consequences and is difficult to measure.
Femoral malrotation is a common, underrecognized complication of intramedullary nailing for femoral shaft fractures that requires accurate measurement (ideally via CT) and potential surgical correction if symptomatic.
Underrecognition of post-nailing femoral malrotation risks functional deficits; leaves optimal measurement protocols open for prospective validation.
Femoral malrotation represents one of the common causes of deformity following intramedullary nailing of femoral shaft fractures that can lead to cosmetic and functional consequences. Femoral malrotation is often underrecognized because femoral rotation is variable amongst the population and even variable within a patient comparing one's own lower extremities. Moreover, femoral malrotation is difficult to measure. Clinical examination, ultrasonography, radiography, and computed tomography have all been described to measure femoral malrotation. In this review, we discuss the IMN complication of femoral malrotation with respect to its definition, functional significance, how to measure it, and treatment.
