“…This is a rare situation that may lead to neurological paraplegia and require complex procedures. In the spinal literature, some authors 18 have proposed the use of a halo-pelvic traction (HPT) apparatus – an external fixation system that provides a gradual correction (between one and two months) before the definitive surgical management – which is normally used between four and eight weeks before surgery. Halo-gravity traction (HGT) has also been proposed to improve curves preoperatively in cases of severe deformities, such as those with great evidence of the kyphotic element over the scoliotic curve with an acute angulation.…”

Type-1 neurofibromatosis (NF1) is a neurocutaneous syndrome classically known as peripheral NF to distinguish it from type-2 NF (central NF). Its main characteristic is the high predisposition to the growth of multiple tumors, which specially arouses the interest of spinal surgeons due to the presence of spinal cord compression and spinal deformities.Considering this, we have performed a comprehensive review, with illustrative cases of the main manifestations of NF1, focusing on the perspective of the spine surgeon. Articles were grouped according to the following subjects: diagnosis, skeletal complications, spinal deformity, and spinal tumors. For all of them, a detailed discussion on pearls for practice was presented.The diagnosis of NF1 is based on the presence of at least two out of seven criteria. Cutaneous findings are very common in NF1, and the most usual tumor is cutaneous neurofibroma (NFB). Plexiform neurofibromas are also found and present a high risk of becoming malignant peripheral nerve sheath tumors (MPNSTs), reducing life expectancy. Astrocytomas, especially pilocytic astrocytomas, are the most common central nervous system tumor, including in the spinal cord. Surgery is necessary to resect as much as possible without adding new neurological deficits. Spinal deformities are also commonly found (in 30–70% of the cases), potentially associated with dystrophic changes, which may result in acute and rapid progression.In the present review, we discuss specific characteristics found in this group of patients which are of paramount importance to properly manage this challenging disease.
