    Treatment of infra-isthmal femoral fracture with an intramedullary nail: Is retrograde nailing a better option than antegrade nailing?
    Arch Orthop Trauma Surg 2018 May 24. Epub 2018 May 24.
    Department of Orthopaedic Surgery, School of Medicine, Kyungpook National University, Kyungpook National University Hospital, 130 Dongduk-ro, Jung-gu, Daegu, 41944, South Korea.
    Introduction: Antegrade intramedullary (IM) nailing is ideal for femoral shaft fractures, but fixing the fracture distal to the isthmal level may be difficult because of medullary canal widening and the proximity of fracture location from the distal femoral joint line. This study aimed to compare treatment results between antegrade and retrograde nailing for infra-isthmal femoral shaft fracture, and to identify influencing factors of nonunion and malalignment.

    Materials And Methods: Sixty patients with infra-isthmal femoral shaft fractures treated with IM nailing and followed-up for > 1 year were enrolled in this retrospective study, 38 in the antegrade nailing group, and 22 in the retrograde nailing group. Read More

    Arthroscopic debridement for septic arthritis of the shoulder joint: post-infectious arthritis is an inevitable consequence?
    Arch Orthop Trauma Surg 2018 May 18. Epub 2018 May 18.
    Department of Orthopaedic Surgery, Arthroscopy and Joint Research Institute, Severance Hospital, Yonsei University College of Medicine, CPO Box 8044, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 120-752, South Korea.
    Purpose: The purpose of this study was to compare clinical outcomes and development of post-infectious arthritis of the shoulder joint after single (Group S) or repeated (Group R) arthroscopic debridement surgeries. We hypothesized that (1) repeated surgeries might be attributable to initial subchondral involvement resulting from septic arthritis and (2) the repeated surgery group would exhibit a higher incidence of post-infectious arthritic changes and inferior clinical outcomes due to prolonged resolution of the infection.

    Methods: This study included 42 patients (single surgery, n = 29; repeated surgery, n = 13) who underwent arthroscopic debridement for septic arthritis and had a minimum of 2 years of postoperative follow-up data. Read More

    Outcomes are equivalent for two-column acetabular fractures either with or without posterior-wall fractures.
    Arch Orthop Trauma Surg 2018 May 17. Epub 2018 May 17.
    Department of Orthopaedic Surgery, School of Medicine, Keimyung University, 56 Dalseong-Ro, Joong-Gu, Daegu, 41931, South Korea.
    Introduction: It is likely that posterior-wall involvement in association with two-column fractures plays a pivotal role in outcomes because of the potential for hip instability if it is not anatomically reduced and fixed. Uncertainty remains about how this fracture is best treated, especially regarding how posterior-wall involvement may affect functional results.

    Materials And Methods: To better understand the role that posterior-wall involvement may play in determining functional results, we compared data for outcomes for patients with posterior-wall involvement and for those without in a consecutive series of two-column fractures. Read More

    Introduction: Revision knee arthroplasty is increasing, and in that case, bone loss management is still a challenging problem. In the last years, the body of literature and interest surrounding porous metal cones has grown, but few systematic evaluations of the existing evidence have been performed. The aim of our systematic review is to collect and critically analyze the available evidence about metal cones in revision knee arthroplasty especially focusing our attention on indications, results, complications, and infection rate of these promising orthopaedic devices.

    Department of Teaching, Research and Development, Schulthess Klinik, Lengghalde 2, 8008, Zurich, Switzerland.
    Introduction: The EuroQol-5 Dimension (EQ-5D) is the most widely used generic instrument to measure quality of life (QoL), yet its application in upper extremity orthopaedics as well as its measurement properties remain largely undefined. We implemented a systematic literature review to provide an overview of the application of EQ-5D in patients with upper extremity disorders and analyse its measurement properties.

    Materials And Methods: We searched Medline, EMBASE, Cochrane and Scopus databases for clinical studies including orthopaedic patients with surgical interventions of the upper extremity who completed the EQ-5D. Read More

    Assessment of pelvic tilt in anteroposterior radiographs by means of tilt ratios.

    Introduction: In anteposterior (AP) radiographs, cup position in total hip arthroplasty and acetabular anatomy in hip-preserving surgery are highly influenced by pelvic tilt. The sagittal rotation of the anterior pelvic plane is an important measurement of pelvic tilt during hip surgery. Thus, correct evaluation of cup position and acetabular parameters requires the assessment of pelvic tilt in AP radiographs. Read More

    Intralesional vs. extralesional procedures for low-grade central chondrosarcoma: a systematic review of the literature.

    Nuclear Medicine Department, IRCCS Regina Elena National Cancer Institute, Via Elio Chianesi 53, Rome, Italy.
    Introduction: Chondroid lesions are very common bone tumors. In most cases, they are benign enchondromas (EC) and, in a minor percentage, chondrosarcomas (CSs), the malignant counterpart. In the latter cases, surgery is the mainstay treatment, because they are chemo- and radio-resistant unless dedifferentiation occurs. Read More

    Limitation of flatfoot surgery in overcorrected clubfeet after extensive surgery.

    Introduction: Flatfoot is a severe complication of extensive clubfoot surgery. In this retrospective study, we evaluated our results following flatfoot surgery in overcorrected clubfeet. The aim was to analyze the success of different surgical techniques, including tarsal osteotomies and arthrodesis, in correcting different types of flatfeet. Read More

    Monosegmental anterior column reconstruction using an expandable vertebral body replacement device in combined posterior-anterior stabilization of thoracolumbar burst fractures.
    Arch Orthop Trauma Surg 2018 Jul 6;138(7):939-951. Epub 2018 Apr 6.
    Department of Trauma Surgery, Medical University of Innsbruck, Anichstraße 35, 6020, Innsbruck, Austria.
    Introduction: In combined posterior-anterior stabilization of thoracolumbar burst fractures, the expandable vertebral body replacement device (VBRD) is typically placed bisegmentally for anterior column reconstruction (ACR). The aim of this study, however, was to assess feasibility, outcome and potential pitfalls of monosegmental ACR using a VBRD. In addition, clinical and radiological outcome of monosegmental ACR was related to that of bisegmental ACR using the same thoracoscopic technique. Read More

    Preoperative PCR analysis of synovial fluid has limited value for the diagnosis of periprosthetic joint infections of total knee arthroplasties.

    Preoperative diagnosis of periprosthetic joint infection (PJI) is important because of the therapeutic consequences. This prospective study was designed to answer the question, if preoperative PCR analysis of the synovial fluid in addition to the culture and the CRP analysis of the blood are helpful for the diagnosis of PJI in knee arthroplasties. Before revision CRP analysis of the blood, cultivation and PCR analysis of synovial fluid of 116 knee endoprostheses were performed. Read More
