Pelvic ring fractures with concomitant large hematomas: diagnostic investigation with arteriography and eventual embolization in 157 trauma patients, with or without contrast extravasation at emergency CT.

Purpose: This study aims to evaluate the diagnostic value of pelvic arteriography in patients with pelvic ring fractures and associated large hematomas, in both cases of positive or negative findings of contrast agent extravasation at emergency CT; in those patients with positive DSA subsequently treated with embolization, correlations with clinical-radiological parameters were investigated.

Materials And Methods: In this single-center retrospective study, patients with acute blunt pelvic trauma showing at CT pelvic ring fractures with associated large (> 3 cm) hematoma, with or without signs of arterial bleeding, were investigated with DSA. Technical success was considered radiographic bleeding control with disappearance of angiographic bleeding; clinical success was defined as clinical bleeding control hemodynamically stable, before applying other surgical maneuvers.

Return to sports after medial unicompartmental knee arthroplasty in patients with concomitant patella-femoral osteoarthritis: multicenter retrospective cohort study with minimum 5-year follow-up.

Purpose: The purpose of our study was to evaluate clinical outcomes and return to sports after medial unicompartmental knee arthroplasty (UKA) in middle-aged active patients with concomitant patella-femoral joint (PFJ) osteoarthritis at time of surgery.

Methods: One-hundred and fifty-one patients who underwent medial fixed-bearing cemented UKA, between 2012 and 2015, for medial unicompartmental osteoarthritis of the knee, were retrospectively reviewed with a minimum 5-year follow-up. The mean age at surgery was 54.
