Pellegrini–Stieda Syndrome

http://www.100md.com 《新英格兰医药杂志》

     A 38-year-old man with an incomplete spinal cord injury secondary to a diving accident some years before, which caused tetraplegia but preserved some sensation below the neck, reported new pain in the left knee during the previous two months. He said there had been no recent trauma to the knee. An anteroposterior radiograph showed ossification corresponding to the medial collateral ligament, findings initially described by Pellegrini and Stieda in the early 1900s. Treatments for mild and moderate cases of the Pellegrini–Stieda syndrome include local corticosteroid injection and range-of-motion exercises. Surgical excision of calcifications and repair of the tear in the medial collateral ligament can be considered for refractory cases.
