Computed tomography of 3 cases of hip trauma

ABSTRACT

CT has been advocated as an adjunct to conventional radiography in the evaluation of pelvic bone fractures andtraumatic dislocations of the femoral head. Author compared and analysed the CT and plain radiographic findings of3 consecutive adult patients in whom acetabular or femoral head injuries were suspected or demonstrated on initialradiographs. The results were as follows; 1. CT was convenient and precise method in evaluation the patient withhip trauma. 2. CT was helpful in detecting intraaraticular osseous fragment, interposed soft tissue, and wideningof the joint space which was not evident on plain radiographs. 3. CT permitted better evaluation of asociatedinjuries in soft tissue and viscera in the plevic and retroperitoneal cavity, and also gave information aboutother associated fractures. 4. CT was superior for the evaluation of posterior acetabular rim and medial portionof the acetabulum. 5. CT was helpful for evaluating the presence or absence of intraarticular osseous fragmentsafter reduction of the dislocated hip.
