Using computed tomography images, we determined the acetabular PLX3397 mw anteversion angle at various levels in the axial plane. The acetabular sector angle served as an indicator of acetabular coverage of the femoral head. We evaluated the association between acetabular version and the patient’s
age at the onset of pain. Fifty normal hips were examined as controls.
Results: We observed acetabular retroversion in 18% (seventeen) of the ninety-six hips in the patients with developmental dysplasia of the hip. The mean acetabular anteversion angle in the hips with acetabular retroversion was significantly smaller, at all levels, than that in the hips with acetabular anteversion; this tendency was more evident at proximal levels. There was significantly less posterior and posterosuperior
coverage in the hips with acetabular retroversion than in those with acetabular anteversion, but superior acetabular coverage did not differ between the groups. Multivariate analysis showed that the onset of pain occurred at a significantly earlier age in patients with acetabular retroversion (27.9 years) than in those with acetabular anteversion (40.5 years), regardless of the severity of the dysplasia (p = 0.003).
Conclusions: In patients with developmental dysplasia of the hip, acetabular retroversion results from relatively deficient coverage by the posterior portion of the acetabulum. Developmental dysplasia with acetabular retroversion is associated with an earlier onset of pain than is developmental dysplasia with anteversion, suggesting a correlation find more between deficiency of the posterior acetabular wall and the earlier onset of pain.”
“Background: Temporary elbow stiffness after the treatment of a supracondylar Fer-1 clinical trial humeral fracture in a child is often a concern of parents. However, little attention has been devoted to documenting, longitudinally, the time required for motion recovery. The purpose of the present study was to provide a prospective, longitudinal evaluation of elbow motion in a large population of pediatric patients undergoing treatment of a supracondylar humeral fracture.
Methods: We prospectively examined
373 patients (375 fractures) who presented to our urgent care center between March 1, 2007, and September 30, 2008. On the basis of a standard protocol, patients were managed with either casting or surgery, depending on the severity of the injury, and then were followed for a minimum of seven weeks. Values of elbow flexion and extension were recorded, and the relative arc of motion was calculated as a percentage of the motion of the contralateral elbow.
Results: In general, following a supracondylar humeral fracture, the greatest increases in flexion, extension, and the absolute and relative arcs of motion are observed within the first month after cast removal, with a progressive improvement for up to forty-eight weeks after the injury.
