%X <B>UNASSIGNED: </B>Acute flaccid myelitis (AFM) is a recently described diagnosis that primarily impacts the pediatric population. It is characterized by profound proximal muscle weakness with resultant orthopedic manifestations similar to well-known neuromuscular conditions. While the incidence of AFM has been rising, management outcomes are understudied. Here, we describe the first known case of hip reconstruction in AFM.<BR><B>UNASSIGNED: </B>A 5-year-old female presented with painful bilateral hip subluxations 2 years after being diagnosed with AFM. Imaging confirmed substantial uncovering of the femoral heads, right greater than left, with reduction on abduction views. Given the extent of her hip pathology and symptoms, she underwent bilateral Dega and varus derotational osteotomies with adductor lengthening, achieving a 35° correction in femoral neck angle and 30° reduction in femoral anteversion bilaterally. At 2 years postoperatively, she was asymptomatic without recurrence of hip displacement.<BR><B>UNASSIGNED: </B>Reconstructive femoral osteotomies can be effective for achieving painless, reduced hips in patients with AFM. Thus, surgeons may reasonably extrapolate current concepts utilized for other low-tone neuromuscular conditions to inform approach to AFM.
