ABSTRACT
Pediatric ankle fractures can cause physeal injuries which can lead to the shortening of the fibula. This induces a lateral shift of the talus, valgus tilt, and instability of the ankle joint, which can result in an arthritic change in this joint. Patients with a shortening of the fibula may complain of constant pain and restricted movements in their daily lives and during sports activities. Ankle reconstruction with fibula lengthening Z-osteotomy can provide excellent results if arthritis is absent or minimal, especially in young and active patients. To the best of the authors’ knowledge, this is the first report in South Korea regarding the treatment of fibula shortening following a growth arrest due to injury.
ABSTRACT
Dermatomyositis (DM) is an idiopathic inflammatory myopathy, characterized by inflammation of the proximal skeletal muscles and typical skin manifestations, which results in symmetric muscle weakness. A 43-year-old man was presented with skin rash and left leg weakness, and he had a history of poliomyelitis. Initially, he was diagnosed as having post-polio syndrome (PPS) due to unilateral muscle weakness and a result of an the electromyography (EMG), which had shown patterns of PPS. After 4 months with conservative therapy for PPS, weakness of bilateral upper arms had developed and skin rashes on his entire body had aggravated and progressed. He was diagnosed as having dermatomyositis, based on elevated muscle enzyme levels, typical skin rashes, and typical EMG findings, which indicated muscle disease. When a patient with previous poliomyelitis has a newly developed muscle weakness or pain, we should consider various possible causes other than PPS.
