Due to its high sensitivity, low cost, accessibility, and ease of use, bone scintigraphy is used in orthopedic surgery for the diagnosis and management of varied pathology. It is commonly used for insufficiency fractures, metastatic neoplasia, staging and surveillance of sarcoma, and nonaccidental trauma. It augments diagnoses, including stress or occult fractures, musculoskeletal neoplasia or infection, and chronic regional pain syndrome, in patients presenting with normal results on radiographs. Bone scan images are resistant to metal-based implant artifact, allowing effective evaluation of failed total joint prostheses. Bone scintigraphy remains an underused tool in the evaluation and management of orthopedic patients. [ Orthopedics . 2019; 42(1):e14–e24.]

The authors present a case of bilateral femoral emphysematous osteomyelitis caused by Escherichia coli in a 60-year-old woman with rheumatoid arthritis who was receiving long-term prednisone therapy. The infection in both femoral shafts was eradicated with surgical debridement, followed by insertion of intramedullary rods composed of culture-specific antibiotic cement into the femoral canals in conjunction with 6 weeks of intravenous antibiotics. The rods were subsequently removed, and no signs of further osteomyelitis were recognized at follow-up. To the authors' knowledge, this is the first case of its kind reported in the orthopedic literature. Emphysematous osteomyelitis, a rare and dangerous entity, can be successfully managed by intramedullary antibiotic delivery in the subacute setting. [ Orthopedics . 2019; 42(1):e128–e130.]

The clinical picture of sarcoidosis varies widely; in many cases there are few symptoms. In cases where the initial symptoms of sarcoidosis are ocular the diagnosis can only be established if systemic disease is considered in differential diagnosis. Five cases with ocular manifestation and unusual findings or development are described.
