Purpose: We report infected hip prostheses treated by an original technique: frontal femorotomy after trochanterotomy.
Material And Methods: This extensive technique enables perfect cleaning of the femur and truly effective freshening of the endomedullar canal. We report 30 cases operated since 1991 use of femorotomy has been systematic from 1995.
Results: We were able to reimplant 25 of these 30 hips. Our results after infection were rather good with 4 recurrent infections in difficult cases (multi-operated patients and multiresistant germs in half of the cases). Fusion of femorotomy was obtained in all cases. The mechanical outcome was not improved by femorotomy. The main problem was trochanter nonunion with 5 cases, all of them having had a trochanteromy during the first procedure.
Discussion: We use femorotomy as our routine technique for femoral cleaning in case of hip prosthesis infection. In less complicated cases, we do not remove the trochanter from the femoral valve, limiting trochanteric complications, the main problem with this technique.

Objective: Obesity is a risk factor for joint arthroplasty complications. With this systematic review and meta-analysis, we assessed whether a positive history of bariatric surgery influences postoperative outcomes in patients undergoing various types of joint arthroplasty.
Methods: We conducted a comprehensive search database such as Scopus, PubMed, Medline Ovid, CNKI, and CENTRAL for studies comparing outcomes between patients undergoing arthroplasty with and without a history of bariatric surgery.

Intramedullary nail fixation is a routine procedure for treatment of intertrochanteric fractures. Aseptic technique is vital for reducing postoperative complications, as intraoperative glove perforations increase the risk of surgical site infections. The aim of this study was to determine the incidence of surgical glove perforation during intramedullary nailing of intertrochanteric fractures and to identify surgery-specific steps at risk.

: Vancomycin is commonly used in the treatment of periprosthetic joint infection (PJI), and trough concentrations are measured to ascertain that they are within the therapeutic range. It has not been investigated what proportion of vancomycin concentrations during treatment of PJI patients is accurately within this range, how many dose adjustments are commonly needed, and which patient factors predispose towards aberrations from the desired range. : In this single-center cohort study, we investigated vancomycin trough concentrations in 108 patients with surgically treated PJI who received IV administered vancomycin treatment post-operatively.

Periprosthetic joint infections (PJIs) are a dangerous complication of joint replacement surgeries which have become much more common in recent years (mostly hip and knee replacement surgeries). Such a condition can lead to many health issues and often requires reoperation. Staphylococci is a bacterial group most common in terms of the pathogens causing PJIs.
