In-office Maximal Voluntary Ventilation Testing Demonstrates Pulmonary Improvement Following Posterior Spinal Fusion for Adolescent Idiopathic Scoliosis.

Objective: Pulmonary function can be impaired in patients with adolescent idiopathic scoliosis (AIS). Maximal voluntary ventilation (MVV) has been shown to be more strongly correlated with major coronal curve, and a more easily obtained measurement of pulmonary function, than forced vital capacity (FVC). We evaluated changes in pulmonary function using these 2 measures in patients with AIS in relation to changes in major coronal curves over time.

Adolescent idiopathic scoliosis patients treated with bracing, surgery, or observation showed no difference in behavioral and emotional function over a 2-year period.

The purpose of this study was to assess if behavior and emotional function, as measured by the Pearson Behavioral Assessment Survey for Children, Second Edition (BASC-2) in patients and parents, changes with differing treatment protocols in patients with adolescent idiopathic scoliosis (AIS). One previous study showed abnormal BASC-2 scores in a substantial number of patients diagnosed with AIS; however, no study has assessed how these scores change over the course of treatment. AIS patients aged 12 to 21 years completed the BASC-2.

Conventional Chondrosarcoma with Clear Cell Features in the Rib: Report of Two Cases and Review of the Literature.

A subset of clear cell chondrosarcomas may contain focal areas of low-grade conventional chondrosarcoma; however, it is rare to find foci resembling clear cell chondrosarcoma admixed with areas otherwise typical conventional chondrosarcoma. We report two patients with conventional chondrosarcoma with clear cell features occurring in the rib, one in the setting of multiple hereditary exostoses (MHE) and the other without MHE. Both patients were found to have a destructive rib mass with a soft tissue component and underwent en bloc resection.

Primary Lymphoma of the Distal Femur Presenting as Spontaneous Deep Vein Thrombosis and Knee Monoarthritis: A Case Report.

Case: A 68-year-old man with a history of unprovoked deep vein thrombosis (DVT) presented with recurrent knee effusions after the initiation of anticoagulation. Radiographs showed soft-tissue swelling without a distinct skeletal lesion. Magnetic resonance imaging, however, showed a marrow-replacing process in the distal femur.
