    Arch Orthop Trauma Surg 2018 Feb 19;138(2):281-286. Epub 2017 Dec 19.
    Adult Reconstruction and Joint Replacement Division, Hospital for Special Surgery, 535 East 70th Street, New York, NY, 10021, USA.
    Introduction: Although metal-on-metal (MoM) total hip arthroplasty (THA) and hip resurfacings (HR) have similar bearing surfaces and comparable wear rates, metal ion levels and risk of failure are higher for MoM-THA. The mechanism behind the increased metal ion levels in large head MoM-THA is not completely understood. The current study aims to identify predictive factors for increased metal ion levels in unilateral and bilateral large head MoM-THA. Read More

    The nail-shaft-axis of the of proximal femoral nail antirotation (PFNA) is an important prognostic factor in the operative treatment of intertrochanteric fractures.

    Department of Orthopaedic and Trauma Surgery, Luzerner Kantonsspital, 6000, Luzern, Switzerland.
    Introduction: Due to the world's aging population, intertrochanteric fractures are frequent. Considering age and comorbidities of most of these patients, it is indispensable to enable early postoperative mobilization of these patients. Intramedullary osteosynthesis with PFN-A is widely used and, in general, considered safe and reliable for the operative treatment of intertrochanteric fractures. Read More

    The relationship between the degree of displacement of the atlas to axis and the clinical data in atlanto-axial subluxation due to rheumatoid arthritis.

    Center for Orthopedics and Trauma Surgery, University Hospital Marburg, Baldingerstrasse, 35043, Marburg, Germany.
    Introduction: The aim of this investigation was to analyse "total blood loss" (TBL), "blood transfusion rate" (BT) and the "amount of transfused blood units" (BU) between the different primary shoulder arthroplasty (SA) types: reverse, anatomical and stemless. Only primary SA was included. Further goal was to identify risk factors for TBL, amount of BU and BT rate. Read More

    Degenerative changes after posterior cruciate ligament reconstruction are irrespective of posterior knee stability: MRI-based long-term results.
    Arch Orthop Trauma Surg 2018 Mar 6;138(3):377-385. Epub 2017 Dec 6.
    Center for Musculoskeletal Surgery, Charité-University Medicine Berlin, Augustenburger Platz 1, 13353, Berlin, Germany.
    Introduction: Posterior cruciate ligament reconstruction (PCLR) is advocated to prevent an early onset of osteoarthritis. We hypothesized that posterior instability after PCLR correlates with degenerative changes.

    Materials And Methods: MRIs of 42 (12 female/30 male; 39 ± 9 years) patients were enrolled with a minimum 5-year follow-up (FFU) after PCLR. Read More

    Medial meniscus grafting restores normal tibiofemoral contact pressures.
    Arch Orthop Trauma Surg 2018 Mar 2;138(3):361-367. Epub 2017 Dec 2.
    Division of Sports Medicine, Department of Orthopaedic Surgery, University of Louisville, Louisville, KY, USA.
    Background: Tissue excision in the setting of a meniscal tear has been shown to dramatically increase peak contact stresses in the affected tibiofemoral joint compartment, leading to the development of degenerative changes and osteoarthritis.

    Purpose/hypothesis: The current in vitro study utilized a porcine model to evaluate the effectiveness of segmental medial meniscal grafting following partial meniscectomy. The study hypothesis was that the procedure would normalize medial tibofemoral joint compartment pressure magnitudes, areas, and locations relative to an intact meniscus. Read More

    Is treatment of geriatric hip fracture patients cost-covering? Results of a prospective study conducted at a German University Hospital.
