Comparative Study for Incidence of Proximal Junctional Kyphosis Between Parathyroid Hormone and Denosumab Following Adult Spinal Deformity Surgery : A Prospective, Randomized Controlled Trial

Medical therapy that can lower PJK rates are also being sought. Teriparatide (TP), a recombinant human parathyroid hormone (PTH 1-34), is a bone forming agent mainly used to treat osteoporotic patients with high risk of osteoporotic fracture. There has been reports suggesting protective effect of prophylactic TP to osteoporotic patients receiving ASD surgery concerning PJK.6 Although it had limitations of small sample size and surgical selection bias owing to study design being retrospective. We hypothesized prophylactic TP would act as to reduce the incidence of PJK and therefore reduce PJF and necessity of revision surgeries in patients after ASD correction surgery. Our study can consolidate the beneficial effect of prophylactic TP to patients receiving ASD surgery by reducing the incidence of PJK.
