To identify the pattern of deltoid ligament injury after acute ankle injury and the relationship between ankle fracture and deltoid ligament tear by magnetic resonance imaging (MRI). ⋯ The observed injury pattern of the deltoid ligament was complex and frequently associated with concomitant ankle pathology. The most common tear site of the superficial deltoid ligament was the medial malleolar attachment, whereas that of the deep pTTL was near its medial talar insertion.

To assess the number and anatomical location of fractures associated with elbow dislocation, to study the correlation between the direction of dislocation and the trauma energy, and to assess radiographs' diagnostic performance characteristics for fractures using MDCT as a reference standard. ⋯ Small fractures and impaction fractures are almost invariably present in elbow dislocations, and half of the patients have more than one fracture. Radiographs have a sensitivity of only 62%. MDCT is an invaluable method for determining the extent of bony injury and revealing occult fractures.

Our goal was to assess the technical results in patients who underwent long-axis sacroplasty for the treatment of sacral insufficiency fractures (SIF) by radiofrequency-induced high-viscosity bone cement augmentation. Twelve patients with bilateral sacral fractures were treated by augmentation with radiofrequency-activated, high-viscosity polymethylmethacrylate (PMMA) bone cement under local anesthesia. CT-guided sacroplasty was performed by using a long-axis approach through a single entry point. ⋯ No major adverse events were observed. In the first 4 days after the procedure, the mean VAS score decreased from 8.1 ± 1.9 to mean 3.1 ± 1.2 and was followed by a gradual but continuous decrease throughout the rest of the follow-up period at 24 weeks (mean 2.2 ± 1.1) and 48 weeks (mean 2.1 ± 1.4). CT fluoroscopy-guided sacral augmentation was safe and effective in all 12 patients with osteoporotic SIF.

To establish baseline T2* values in healthy knee joint cartilage at 3 T. ⋯ Substantial regional differences in T2* measures should be taken into consideration when conducting T2* mapping of knee joint cartilage.

Review Case Reports
Empty toe phenomenon: a big problem for a little toe.
The authors present a case report and review of the sparse literature of a rare closed degloving injury to the toe, referred to by Flaherty as an "empty toe phenomenon." A 25-year-old man sustained a twisting injury to his left foot when he was involved in a motorcycle accident. The skin was not lacerated around the toe but on physical exam it appeared that part of the toe was empty of its bony contents.
