    Background: (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT) has proven to have a high diagnostic accuracy for the detection of bone infections. In patients with delayed union it may be clinically important to differentiate between aseptic and septic delayed union. The aim of this study was to evaluate the efficacy and to assess the optimal diagnostic accuracy of FDG-PET/CT in differentiating between aseptic and septic delayed union in the lower extremity.

    Department of Orthopedics, Faculty of Medicine, Chiang Mai University, Chiang Mai, 50200, Thailand.
    Introduction: Cerclage wiring for reduction of complex femoral shaft fractures can create iatrogenic vascular injury.

    Objective: To describe the anatomical relation of blood vessels to the femur and develop a technical guide for safe passage of cerclage wire.

    Materials And Methods: CT lower-limb angiographs (CTA) of 80 patients were reviewed and analysed to identify the superficial femoral artery (SFA) and the deep femoral artery (DFA) as well as the relation of those arteries to the femoral cortex. Read More

    Exchange nailing with enhanced distal fixation is effective for the treatment of infraisthmal femoral nonunions.

    Department of Orthopaedic Surgery, Korea University College of Medicine, Guro Hospital, 97 Gurodong-gil, Guro-gu, Seoul, 152-703, Korea.
    Introduction: The treatment options for nonunions of infraisthmal femoral shaft fractures after internal fixation are controversial. Methods such as exchanging an existing nail with a nail of a larger size, dynamization, removal of the nail followed by plating, and bone grafting have all been reported. Among those options, exchange nailing seems to be the most popular choice. Read More

    Limited diagnostic accuracy of magnetic resonance imaging and clinical tests for detecting partial-thickness tears of the rotator cuff.

    Sporthopaedicum Berlin, Bismarckstraße 45-47, 10627, Berlin, Germany.
    Introduction: The reliable diagnosis of partial-thickness tears of the rotator cuff is still elusive in clinical practise. Therefore, the purpose of the study was to determine the diagnostic accuracy of MR imaging and clinical tests for detecting partial-thickness tears of the rotator cuff as well as the combination of these parameters.

    Materials And Methods: 334 consecutive shoulder arthroscopies for rotator cuff pathologies performed during the time period between 2010 and 2012 were analyzed retrospectively for the findings of common clinical signs for rotator cuff lesions and preoperative MR imaging. Read More

    No influence of obesity on survival of cementless, posterior-stabilised, rotating-platform implants.

    Introduction: This study compares survival and outcomes in four total knee arthroplasty (TKA) populations defined by baseline body mass index (BMI). We hypothesised that there would be no difference in survival between the groups.

    Materials And Methods: Using an initial cohort of 1059 TKAs, BMI was systematically measured prior to surgery. Read More

    Effects of intra-operative fluoroscopic 3D-imaging on peri-operative imaging strategy in calcaneal fracture surgery.
    Arch Orthop Trauma Surg 2017 Dec 21;137(12):1667-1675. Epub 2017 Sep 21.
    Trauma Unit, Department of Surgery, Academic Medical Center, 1105 AZ, Amsterdam, The Netherlands.
    Introduction: Previous studies demonstrated that intra-operative fluoroscopic 3D-imaging (3D-imaging) in calcaneal fracture surgery is promising to prevent revision surgery and save costs. However, these studies limited their focus to corrections performed after 3D-imaging, thereby neglecting corrections after intra-operative fluoroscopic 2D-imaging (2D-imaging). The aim of this study was to assess the effects of additional 3D-imaging on intra-operative corrections, peri-operative imaging used, and patient-relevant outcomes compared to 2D-imaging alone.

    Institute for Orthopaedic Research and Training, KU Leuven, Campus Pellenberg, Louvain, Belgium.
    Introduction: Fixed-bearing unicompartmental knee arthroplasty (UKA) closely replicates native knee kinematics. As few studies have assessed kinematics following mobile-bearing (MB) UKA, the current study aimed to investigate whether MB UKA preserves natural knee kinematics.

    Materials And Methods: Seven fresh-frozen full-leg cadaver specimens were prepared and mounted in a kinematic rig that allowed all degrees of freedom at the knee. Read More
