RESUMO
Post-traumatic lipid inclusion cysts are a rare entity seen following fractures in paediatric patients. They often occur in the distal radius, developing 1-3 months following an extra-articular fracture. Although benign and self-limiting in nature, adequate awareness and accurate radiographic interpretation is key in avoiding further unnecessary non-invasive or invasive investigations. We report on a case of post-traumatic lipid inclusion cyst and review the literature.
RESUMO
Metal-on-metal disease (MOMD) is a rare condition following arthroplasty and has predominantly been reported following hip and knee replacement. Isolated case reports exist with respect to MOMD following total wrist arthroplasty-however, the literature remains limited. Here, we present the history and radiographic and histopathologic features of such a case, and summarize the literature and provide management recommendations.

Avascular necrosis (AVN) of the ankle and foot is an uncommon and often unexpected postoperative complication in patients with persistent pain and disability postprocedure. Artifacts from metallic implants may obscure characteristic imaging signs of AVN, and radiography and computer tomography are the mainstay imaging modalities of the postoperative ankle and foot. MRI and nuclear medicine imaging play an important complementary role in problem solving and excluding differential diagnostic considerations including infection, nonunion, occult fracture, and secondary osteoarthritis.This review article evaluates different imaging modalities and discusses characteristic sites of AVN of the ankle and foot in the postoperative setting including the distal tibia, talus, navicular, and first and lesser metatarsals. Radiologists play a key role in the initial diagnosis of postoperative AVN and the surveillance of temporal evolution and complications including articular collapse and fragmentation, thus influencing orthopedic management.
