Chronic Anterior Pelvic Instability.

Introduction: Chronic anterior pelvic instability means pathologic movement of the symphysis pubis with axial load. It is not a common pathology and its diagnosis is often delayed and difficult increasing the disability of affected patients. The pain is localized in the suprapubic area or groins, increasing with physical activity, direct palpation or compression.

Long-term results of acute prosthetic joint infection treated with debridement and prosthesis retention: a case-control study.

Purposes: To evaluate the long-term outcome (at least 4 years) of patients who underwent a surgical debridement due to an acute prosthetic joint infection (PJI) and to compare them with a control group that did not have an acute septic complication.

Methods: From January 1999 to December 2007, 61 patients with an acute PJI in remission after 2 years of follow-up (cases) were retrospectively reviewed and compared with a control group (2:1) without an acute PJI matched by age, year of arthroplasty, and type of prosthesis. Septic and aseptic complications of each group were gathered and compared using a chi-square test.

Relationship between haematoma in femoral neck fractures contamination and early postoperative prosthetic joint infection.

Introduction: Prosthetic joint infection (PJI) after femoral neck fracture is associated with a higher mortality, morbidity and economic costs. Although is well known that the presence of a post surgical haematoma is associated with infection, in our knowledge there are no articles evaluating the contamination of the femoral neck fracture haematoma and the possible relationship with early postoperative PJI. The aim of our study was to evaluate the prevalence of positive cultures from haematoma in patients with femoral neck fracture and the relationship with early PJI.
