The rise in popularity of hip arthroscopy has led to a renewed interest in mild hip dysplasia. There is a lack of clarity in the literature regarding both the diagnosis and management of such patients. The aim of this study was to analyse the relative importance of and the inter-relationship between the classically described anatomical indices of dysplasia.One hundred and fifty hips with varying degrees of hip dysplasia were studied. The following were measured: centre-edge (CE), Sharp's and Tönnis angles, acetabular head index (AHI), and acetabular index of depth to width (AIDW). Spearman's correlation coefficient was calculated.Using the CE angle 82 hips were classified as normal and 68 dysplastic. Of the 82 patients with a normal CE angle, 20-39% were dysplastic on at least one other variable. The CE angle did not have a significant correlation to other variables. The remaining four variables showed inter-correlations between 0.26 and 0.54. Overall the Tönnis angle showed the strongest correlation with the other variables. In the patient group with CE angles 21o to 25o (minor dysplasia) 72% of hips had Tönnis angles greater than 10o and 28% had angles greater than or equal to 15o indicating the great variability in the level of dysplasia within this group.In patients with mild dysplasia we have shown that measurement of a single anatomical variable may lead to under-diagnosis. We recommend the measurement the CE angle combined with at least one other variable and suggest the use of the Tönnis angle.
Background: Valvar heart disease is an important public health problem, more common in developing countries, especially in younger.Objective: To evaluate the epidemiological features of patients and its influence on the prosthesis type choice used on patients who underwent valve surgery.Methods: Cross-sectional. Data such as age, sex, provenance, surgery procedure and prosthesis type were retrospectively analyzed. We reviewed 366 charts of all patients submitted to heart valve surgery during three years in a public health cardiovascular treatment center.Results: 52% of patients were female. The age range was from 5 to 82, the median was 41 years old. In regards 37.7% of patients came from Salvador (Bahia, Brazil) and 62.3% from countryside. Valve replacement was performed in 73% of patients, whereas 7.38% underwent valvuloplasty and 18.3% underwent valve repair and replacement. Regarding type of prosthesis, 70.0% received bioprosthesis and 30.0% received metal prosthesis. On note bioprosthesis were more used in younger (66 vs. 14; P<0,001).Conclusion: Biological prostheses were used predominantly in younger. This might be possible due to a low social-economic status, avoiding metal valve implantation and the consequent anticoagulation therapy.

ObjectiveTo evaluate the influence of the type of prosthesis in-hospital mortality in the
post-operative period in patients who had valve replacement.MethodsA cross-sectional data, such as gender, origin, age, etiology, echocardiograph
data, the type of surgery performed and the prosthesis used in cases of valve
replacement were analyzed retrospectively.ResultsWe reviewed 353 charts of patients who underwent valve replacement surgery. The
mean age was 41.87±17.9 years. Regarding gender, 52.8% were female. As for
the origin, 61.1% came from small cities within the state. Of all patients, 58.5%
suffered from rheumatic disease. Assessing the type of prosthesis implanted, 70%
held replace by bioprosthesis and 30% metallic. The hospital mortality in this
study was 11%, with no significant difference between the types of prosthesis
utilized.ConclusionThe type of implant used had no effect on in-hospital mortality.
