Schatzker IV tibial plateau fractures: are they always unicondylar?

Objective: The objectives of this study were to describe the incidence and morphology of medial tibial plateau fractures that extend into the lateral articular surface and to describe trends in their management.

Design: Retrospective.

Setting: Level I Urban Trauma Center.

Efficacy and Accuracy of Diagnosing Septic Arthritis: How Effective are Current Methods for Timely Diagnosis of Septic Arthritis?

The diagnosis of septic arthritis requires a reliance on ancillary tests, including synovial fluid white blood cell count (jWBC), percentage of polymorphonuclear leukocytes (%PMN), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). This study evaluated these tests to determine their diagnostic utility in suspected septic arthritis. A retrospective chart review was performed on patients admitted to an urban hospital who underwent arthrocentesis.

Isolated Lateral Plating for Bicondylar Tibial Plateau Fractures: Factors Influencing Decision Making.

Lateral plating alone has been postulated as an alternative for fixation of bicondylar tibial plateau fractures in attempts to limit morbidity associated with dual plating. Characterization of fracture patterns that may facilitate lateral plating alone for bicondylar tibial plateau fractures is not well established. The authors analyzed radiographic and clinical outcomes of isolated lateral plating in patients with at least 6 months of follow-up.

Unique Case of Accelerated Bone Growth Precipitating a One-Stage Masquelet: A Case Report.

Introduction: The masquelet technique is a two-stage procedure used by orthopedic surgeons to treat large segmental bone defects secondary to infection, trauma, and tumor resection. This technique characteristically requires the placement of a temporary cement spacer and subsequent bone grafting for complete reconstruction. We describe a unique case of segmental bone loss reconstruction in which a patient successfully achieved fracture union after the first step of the masquelet technique without bone grafting.

Cost-effectiveness analysis of the Geriatric Fracture Center (GFC) concept: a prospective multicentre cohort study.

Introduction: Geriatric Fracture Centers (GFCs) are dedicated treatment units where care is tailored towards elderly patients who have suffered fragility fractures. The primary objective of this economic analysis was to determine the cost-utility of GFCs compared with usual care centres.

Methods: The primary analysis was a cost-utility analysis that measured the cost per incremental quality-adjusted life-year gained from treatment of hip fracture in GFCs compared with treatment in usual care centres from the societal perspective over a 1-year time horizon.

A retrospective review of the rate of septic knee arthritis after retrograde femoral nailing for traumatic femoral fractures at a single academic institution.

Background: Retrograde intramedullary nailing of the femur is a popular treatment option for femoral shaft fractures. However, this requires accessing the intramedullary canal through the knee, posing a risk of intra-articular infection. The purpose of this study was to examine the rate of intra-articular infection of the knee after retrograde nailing of femoral shaft fractures.

Extraskeletal Myxoid Chondrosarcoma Identified in a Traumatic Fracture of the Toe: A Case Report.

Introduction: Extraskeletal myxoid chondrosarcoma (EMC) is a rare soft-tissue sarcoma that typically presents in the proximal lower extremity and limb-girdle. It can be easily misdiagnosed, especially when located in atypical locations like the foot.

Case Report: We present the case of an 80-year-old Caucasian female with a left 3rd toe pain and swelling that was initially misdiagnosed as a traumatic fracture on radiographs but later determined to be an indolent EMC based on histology.

Infection of Baker's Cyst without Bacteremia, Sepsis, or Extraneous Source: A Case Report.

Introduction: Baker's cysts are benign fluid-filled cysts that commonly form around knee joints which typically resolve spontaneously. Infection of baker's cysts is uncommon, but most often associated with septic arthritis or bacteremia. We describe a unique case of an infected Baker's cyst that presented without bacteremia, septic knee, or external source of infection.

Biomechanical analysis of dual versus lateral locked plating in elderly bicondylar tibial plateau fractures: Does medial comminution matter?

Objective: To assess dual plating versus lateral locked plate fixation of bicondylar tibial plateau fractures in an elderly cadaveric model with and without medial bone loss PARTICIPANTS: 10 pairs of elderly (range 78-93 years of age) fresh frozen tibias.

Intervention: Bicondylar tibial plateau fractures were created reproducing AO/OTA 41 C1 (without medial bone loss) and C2 fractures (with medial bone loss). Cadavers were randomized to 4 different groups.

Geriatric fracture centre vs usual care after proximal femur fracture in older patients: what are the benefits? Results of a large international prospective multicentre study.

Objective: The aim of this study was to determine the effect of treatment in geriatric fracture centres (GFC) on the incidence of major adverse events (MAEs) in patients with hip fractures compared with usual care centres (UCC). Secondary objectives included hospital-workflow and mobility-related outcomes.

Design: Cohort study recruiting patients between June 2015 and January 2017.

Permanent reduction plate and intramedullary nailing of open tibia fractures: Do we need to take them out?

Introduction: Provisional reduction plating has been advocated as a reduction aid for tibial shaft fractures. Concerns regarding soft tissue stripping, infection, wound complications and nonunion have been postulated. Recent studies investigating reduction plating present patient cohorts where plates are removed or left to the discretion of the surgeon.

Accuracy of Posterior Wall Acetabular Fracture Lag Screw Placement: Correlation Between Intraoperative Fluoroscopy and Postoperative Computer Tomography.

Objective: Compare intraoperative "on end" fluoroscopy lag screw position to postoperative computer tomography.

Design: Retrospective review.

Clinical Setting: Level 1 trauma center.

Autonomic regulation of voltage-gated cardiac ion channels.

Altering voltage-gated ion channel currents, by changing channel number or voltage-dependent kinetics, regulates the propagation of action potentials along the plasma membrane of individual cells and from one cell to its neighbors. Functional increases in the number of cardiac sodium channels (Na(V)1.5) at the myocardial sarcolemma are accomplished by the regulation of caveolae by beta adrenergically stimulated G-proteins.
