Paraplegia in an Ankylosing Spondylitis Patient with a Neglected Spine Fracture after Osteosynthesis for Fracture of the Femur: A Case Report

Study Design: Case report. Objectives: To report a case of paraplegia in a patient with thoracic kyphosis after osteosynthesis for a fracture of the femur. Summary of the Literature Review: There are few reports about cases of paraplegia after low extremity fracture surgery in patients with thoracic kyphosis with ankylosing spondylitis. Materials and Methods: An 86-year-old female patient presented with right hip pain. She had undergone surgery for an intertrochanteric fracture of the femur in the supine position under general anesthesia. Immediately after surgery, she showed paraplegia. Postoperative thoracolumbar spine images revealed a fracture through the disc at T12 and L1. However, she did not complain of back pain or any neurologic deficits before surgery. Results: Although the patient underwent emergent posterior decompression and fusion surgery, her neurologic compromise did not improve during 1 year of follow-up. Conclusions: It is necessary to check preoperative spine radiographs before surgery in elderly patients who have a kyphotic deformity and lower extremity fractures. Surgeons should consider changing the position of the patient and the type of anesthesia used during surgery when spine stability is in doubt.
