Hyperlordosis Secondary to Myasthenia Gravis Successfully Treated With Brace-wearing and Lordosis Exercises: A Case Report

Spinal deformities secondary to Myasthenia Gravis (MG) are rarely reported and mainly include scoliosis. In this study, we report a case of hyperlordosis with MG origin, which has not been reported earlier. The patient was a 12-year-old boy who underwent thymectomy at the age of three, and the disease was well-controlled afterward. One year ago, the patient presented with fatigue and severe low back pain associated with walking, while his parents noticed his buttocks jut out more than normal. The radiologic evaluation revealed a hyperlordosis of 100º. The patient was treated with a Milwaukee brace and lordosis exercises. One year after the treatment, an improvement of 27º was observed in the hyperlordosis of the patient. While bracing does not typically treat a neuromuscular deformity, the present case reveals the value of bracing in the treatment of hyperlordosis with MG origin.
