Femoral nerve inguinal approach versus proximal femoral triangle ap proach for continuous regional analgesia in active rehabilitation after total knee arthroplasty: A prospective, randomised study.

Background: A catheter in femoral nerve block (F-Cath) is an effective regional analgesia technique in total knee arthroplasty (TKA) but results in significant quadriceps weakness. The femoral triangle catheter (FTB-Cath) seems to be an interesting alternative. In this study, we aim to demonstrate that the nerve block administration for analgesic purposes via an FTB-Cath results in less quadriceps weakness than via an F-Cath.

Reliability of a new hip lateral view to quantify alpha angle in femoroacetabular impingement.

Background: Radiographic measurement of the alpha angle (AA) in femoroacetabular impingement (FAI) is not well codified and invasive techniques such as MR- or CT-arthrography remain the gold standard. Excessive acetabular coverage described in pincer-type FAI can be seen on plain radiographs but has never been quantified and anterior center edge (ACE) angle, described on the false-profile view (FP) to measure anterior acetabular coverage has never been evaluated in FAI.

Hypothesis: In this study we wanted to determine if a plain radiograph could efficiently measure AA compared to CT-arthrography and if ACE could quantify the acetabular coverage in FAI.

First report of a hip prosthetic and joint infection caused by Lactococcus garvieae in a woman fishmonger.

We describe the first case of hip prosthetic infection due to Lactococcus garvieae. The patient, a 71-year-old woman fishmonger, developed a hip infection 7 years after total hip arthroplasty. The origin of infection was possibly due to the manipulation or intake of seafood or fish contaminated with Lactococcus garvieae.

Long bones giant cells tumors: treatment by curretage and cavity filling cementation.

Objective: Giant cell tumors (GCT) of bone are benign tumors with local aggressiveness that most of the time occur around the metaphyseal area of long bones, often in contact with the articular cartilage. Their treatment remains controversial because of their high recurrence rate. The authors report a retrospective series of 30 cases treated using curettage followed by cementation.
