RESUMO
We estimated the predictive value of methicillin-resistant Staphylococcus aureus (MRSA) nasal polymerase chain reaction (PCR) for blood, bone, and soft-tissue cultures. The specificities were 88.8%, 88.5%, and 92.7% for all cultures, blood cultures, and bone and soft-tissue cultures respectively, and the negative predictive values were 99.3%, 99.8%, and 92.7% respectively.
RESUMO
Bone tumors of the foot are an uncommon finding. Most tumors are found incidentally on imaging and are benign. Care must be taken although due to the aggressive nature of malignant bone tumors that can occur in the calcaneus. Malignant lesions will more commonly present with symptoms of pain and swelling. Often misdiagnosed as soft tissue injuries, it is critical to be able to diagnose and treat these lesions early. Imaging plays an important role with plain films and advanced imaging. Surgical treatments can range from curettage with grafting to amputation for more aggressive lesions.

Revision surgeries, as well as conversions from implants to arthrodesis, can present unique challenges to the foot and ankle surgeon. Proper perioperative planning assists in optimizing the outcome of the procedure. In general, some amount of bone loss and/or shortening of the first metatarsal takes place, leading to the need for augmenting the site with bone graft or a synthetic substitute. Fixation also plays a key role in obtaining a successful conversion. A solid construct combined with bone graft assists the foot and ankle surgeon in achieving an optimal outcome.

"Lapidus arthrodesis is becoming more of a common procedure for treatment of hallux valgus deformities. Like other procedures, complications are possible. The common complications associated with Lapidus arthrodesis procedures include nonunion and malunion. Malunion is typically broken down into recurrence, elevated first ray, shortened first ray, or plantarflexed first ray. This article discusses these common complications after Lapidus arthrodesis.

Optimal healing for fractures requires anatomic reduction and stable fixation. This optimizes not only bone healing, but optimal function within the limb including joint functioning. Proper ligamentous healing is also crucial for optimal functioning. In patients with injuries around the ankle involving distal tibiofibular syndesmotic injuries of the ankle, malreduction of the syndesmosis is a potential consequence that can lead to chronic pain and functional limitations. This article discusses proper ways of evaluating reduction of the syndesmosis and surgical revision for the chronic injury.
