The CT finding of mediastinal hemorrhage alone is sensitive for traumatic aortic injury, but the finding of aortic injury is more specific.

Background Total hip arthroplasty (THA) in the presence of developmental dysplasia of the hip (DDH) can be technically challenging. Restoring the anatomic center of hip rotation may require femoral osteotomy. Techniques using cementless components are widely reported but less is known about using cemented components that may be more appropriate with osteopenic bone. Questions/purposes We therefore determined the rate of union, complications, and early functional score in a series of patients with DDH who underwent cemented THA and simultaneous subtrochanteric osteotomy. Methods We retrospectively reviewed 28 patients (35 hips) who underwent a cemented THA for DDH at a mean age of 47.3 years. Two patients (two hips) died within 12 months of surgery of unrelated conditions. The clinical notes and radiographs were reviewed with a minimum followup of 2 years (mean, 5.6 years; range, 2-14 years). Complications were noted. SF-12 and Oxford hip scores (OHS) were recorded for 18 patients preoperatively and after 6 and 12 months. Results Union occurred in 32 of 33 femora (97%); one patient had an infected nonunion. The overall revision rate was 20% (9% femoral revision rate). There were three dislocations, two of which had further surgery. Two patients had a transient neuropraxia. The mean SF-12 physical component score increased from 32 to 52 and mean SF-12 mental component score increased from 48 to 51. The mean OHS decreased from 40 to 27. Conclusion Combined subtrochanteric osteotomy and cemented THA is technically demanding with a higher complication rate than routine THA. The rate of union, complications, implant survival, and early OHS were comparable to those for similar techniques using cementless components.

Key Clinical MessageSclerosing angiomatoid nodular transformation (SANT) of spleen is a very rare benign entity with unknown etiology. Here, we report this unusual case in a fit middle-aged gentleman and discuss various diagnostic modalities along with the management of this condition.

Both the centre of the chest landmark and inter-nipple line identify positions on the lower third of the sternum. The centre of the chest technique identifies a point that is consistently higher and more variable than the inter-nipple line. Structures compressed under both landmarks were different although the implications of this are unknown.
