Diagnostic Value of Ischial Spine Sign in Patients with Acetabular Retroversion.

Background: Acetabular Retroversion (AR) is a hip disorder and one of the causes of pain in this area. Evaluation of positive Cross Over Sign (COS) on AP X-Rays of the hip is currently the best method of diagnosis of AR. Several studies have measured co-existence of Ischial Spine Sign (ISS) in patients with AR.

Serum D-Dimer Test Is Promising for the Diagnosis of Periprosthetic Joint Infection and Timing of Reimplantation.

Background: Despite the availability of a battery of tests, the diagnosis of periprosthetic joint infection (PJI) continues to be challenging. Serum D-dimer assessment is a widely available test that detects fibrinolytic activities that occur during infection. We hypothesized that patients with PJI may have a high level of circulating D-dimer and that the presence of a high level of serum D-dimer may be a sign of persistent infection in patients awaiting reimplantation.
