Abstract
BACKGROUND The goal of this study was to report the results of selective open reduction and internal fixation of fractures of the posterior malleolus with a posterolateral approach and to compare the results of the 2 techniques. METHODS We prospectively evaluated 40 patients who underwent posterior malleolar fracture fixation between 2008 and 2012. The patients were treated with a posterolateral approach. We assigned alternating patients to receive plate fixation and the next screw fixation, consecutively, based on the order in which they presented to our institution. Fixation of the posterior malleolus was made with lag screws in 20 patients and a buttress plate in 20 patients. We used American Orthopaedic Foot and Ankle Society (AOFAS) scores, range of motion (ROM) of the ankle, and radiographic evaluations as the main outcome measurements. The mean follow-up was 38.2 (range, 24-51) months. RESULTS Full union without any loss of reduction was obtained in 38 of the 40 patients. We detected a union with a step-off of 3 mm in 1 patient in the screw group and a step-off of 2 mm in 1 patient in the plate group. At the final follow-up, the mean AOFAS score of the patients regardless of fixation type was 94.1 (range, 85-100). The statistical results showed no significant difference between the patients regardless of the fixation type of the posterior malleolus in terms of AOFAS scores and ROM of the ankle (P > .05). CONCLUSIONS Good (AOFAS score of 94/100) and equivalent (within 3 points) results were obtained using the 2 techniques (screws or plate) for fixation after open reduction of posterior malleolar fragments. LEVEL OF EVIDENCE Level II, prospective case series.

Abstract
BACKGROUND Previous studies have suggested that the co-expression of two different bone morphogenetic protein (BMP) genes can result in the production of heterodimeric BMPs that may be more potent than homodimers. In this study, combined BMP-2 and BMP-7 gene transfer was performed ex vivo to compare the resulting new bone formation with that of single-BMP gene transfer in a rat spinal fusion model. METHODS Forty-four athymic rats underwent posterolateral fusion at L4-L5 and were implanted with a collagen sponge containing human adipose-derived stem cells. Group A received untreated cells, and the remaining groups received cells transfected with various genes in a lentivirus vector. The transferred genes were GFP (green fluorescent protein) in Group B, BMP-2 in Group C, BMP-7 in Group D, and both BMP-2 and BMP-7 in Group E. In vitro production of BMP-2 and BMP-7 was quantified by means of an enzyme-linked immunosorbent assay (ELISA) specific to BMP-2 or BMP-7. Osseous fusion was quantified with use of radiography and microcomputed tomography. RESULTS ELISA demonstrated that Group E, which was treated with both BMP-2 and BMP-7, produced less than one-fourth as much BMP as the groups treated with a single transfected BMP (Groups C and D). Radiographs showed that all of the spines in Groups C, D, and E appeared to be fused by eight weeks; the spines in Groups A and B showed minimal evidence of new bone formation. Measurements confirmed that the mean bone formation area was significantly greater in Groups C, D, and E compared with Groups A and B (p < 0.001). In addition, the bone formation area was significantly greater in Group E compared with Groups C and D (p < 0.001). CONCLUSIONS Combined BMP-2 and BMP-7 ex vivo gene transfer was found to be significantly more effective for inducing new bone formation compared with ex vivo gene transfer of an individual BMP in a rat spinal fusion model. CLINICAL RELEVANCE Combined BMP-2 and BMP-7 therapy may lead to efficient bone regeneration.

Abstract
Background: Chest-X-ray has several limitations in detecting the extent of pulmonary disease in sarcoidosis. It might not reflect the degree of pulmonary involvement in patients with sarcoidosis when compared to computed tomography of the thorax. We aimed to investigate the HRCT findings of pulmonary sarcoidosis and to find out the existence of possible relations between HRCT findings and PFTs. In addition, we aimed to investigate the accordance between HRCT findings and conventional chest-X-ray staging of pulmonary sarcoidosis. Method: 45 patients with sarcoidosis with a mean age 29.7+/− 8.4 years were evaluated. Six of them were female and 39 were male. The type, distribution and extent of the parameters on HRCT/CTs were evaluated and scored. Chest-X-rays were evaluated for the stage of pulmonary sarcoidosis. Correlations were investigated between HRCT/ CT parameter scores, Chest X-Ray stages and pulmonary function parameters. Results: Nodule, micronodule, ground glass opacity and consolidation were the most common HRCT findings. There were significant correlations between pulmonary function parameters, HRCT pattern scores, and chest-X-ray stages. A significant correlation between chest-x-ray score and total HRCT score was found. Conclusions: Pulmonary sarcoidosis patients might have various pulmonary parenchymal changes on HRCT. Thorax HRCT was superior to chest-X-ray in detecting pulmonary parenchymal abnormalities. The degree of pulmonary involvement might be closely related to the loss of pulmonary function measured by PFTs. Chest-X-ray is considered to have a role in the evaluation of pulmonary sarcoidosis.
