Purpose Optimal positioning of acetabular components is crucial for maintaining stability of THA. Postoperative assessment of acetabular anteversion is a vital but difficult task. Various methods have been devised with good results for measuring anteversion on plain radiographs but these methods are either too complicated or require special objects like scientific calculators, special protectors, tables, etc. A new simplified method of measuring anteversion on plain radiographs was created based on basic geometry.

purpose. To evaluate treatment outcomes of closed reduction and percutaneous screw fixation for tibial plateau fractures. Methods. 48 men and 8 women aged 19 to 61 (mean, 36) years underwent closed reduction and percutaneous screw fixation for closed tibial plateau fractures with <5 mm depression. According to the Schatzker classification, patients were classified into type I (n=9), type II (n=22), type IV (n=5), and type V (n=20). Closed reduction was achieved using manual ligamentotaxis with traction in extension under image intensifier control. Reduction was fixed percutaneously with cancellous screws (6.5 mm) and washers. Functional outcome (pain, walking capacity, extension lag, range of motion, and stability) was evaluated using the Rasmussen score. A total score of 28 to 36 was considered as excellent, 20 to 27 as good, 10 to 20 as fair, and <10 as poor. results. Patients were followed up for a mean of 2.8 (range, 1-4) years. The mean length of hospital stay was 5 (range, 2-15) days. All the fracture united Closed reduction and percutaneous screw fixation for tibial plateau fractures radiographically after a mean of 3 (range, 2.5-4.2) months. Respectively in Schatzker types-I, -II, -IV, and -V fractures, outcomes were excellent in 6, 10, 2, and 2 patients, good in 2, 9, 3, and 14 patients, fair in 1, 3, 0, and 2 patients, and poor in 0, 0, 0, and 2 patients. Outcome was satisfactory (good-to-excellent) in 89%, 86%, 100%, and 80% of the respective fracture types of patients. The mean Rasmussen score was 25.7 for all patients; it was 27.7 for type I, 26.3 for type II, 28.6 for type IV, and 23.4 for type V fractures. The mean Rasmussen score was significantly lower in 12 patients with ligament injury than in 44 patients without ligament injury (19.8 vs. 27.3, p<0.001). No patient had any complication (infection, wound dehiscence or hardware problem). conclusion. Closed reduction and percutaneous screw fixation for tibial plateau fractures is minimally invasive. It reduces the length of hospital stay and costs, enables early mobilisation with minimal instrumentation, and achieves satisfactory outcomes.

Study DesignCross-sectional study.PurposeThe aim of the study was to determine relationship between the degrees of radiologically demonstrated anatomical lumbar canal stenosis using magnetic resonance imaging (MRI) and its correlation with the patient's disability level, using the Oswestry Disability Index (ODI).Overview of LiteratureThe relationship between the imaging studies and clinical symptoms has been uncertain in patients suffering from symptomatic lumbar canal stenosis. There is a limited number of studies which correlates the degree of stenosis with simple reproducible scoring methods.MethodsFifty patients were selected from 350 patients who fulfilled the inclusion criteria. The patients answered the national-language translated form of ODI. The ratio of disability was interpreted, and the patients were grouped accordingly. They were subjected to MRI; and the anteroposterior diameters of the lumbar intervertebral disc spaces and the thecal sac cross sectional area were measured. Comparison was performed between the subdivisions of the degree of lumbar canal stenosis, based on the following: anteroposterior diameter (three groups: normal, relative stenosis and absolute stenosis); subdivisions of the degree of central canal stenosis, based on the thecal sac cross-sectional area, measured on axial views (three groups: normal, moderately stenotic and severely stenotic); and the ODI outcome, which was also presented in 20 percentiles.ResultsNo significant correlation was established between the radiologically depicted anatomical lumbar stenosis and the Oswestry Disability scores.ConclusionsMagnetic resonance imaging alone should not be considered in isolation when assessing and treating patients diagnosed with lumbar canal stenosis.
