The missed chapter on midfoot: Chopart injuries.

Purpose: Midtarsal injuries are often missed at initial presentation which may lead to long-term complications. Nonetheless, radiographs (XR) are used as a primary imaging method. The place of cone beam computer tomography (CBCT) remains unclear in the management of midfoot injuries.

Assessment of radiation dose values in common orthopaedic trauma examinations performed under X-ray fluoroscopy guidance.

This study aims to provide radiation reference levels in orthopaedic surgery. A total of 753 procedures were collected within 1 y. Categories containing several similar procedures were created based on four criteria: same anatomical area, same level of complexity, only single procedures, and at least 10 cases per category.

Clinical and radiological risk factors associated with the occurrence of acute compartment syndrome in tibial fractures: a systematic review of the literature.

Introduction: Acute compartment syndrome (ACS) is an orthopedic emergency that may lead to devastating sequelae. Diagnosis may be difficult. The aim of this systematic review is to identify clinical and radiological risk factors for ACS occurrence in tibial fractures.

Postfasciotomy Classification System for Acute Compartment Syndrome of the Leg.

Objective: Acute compartment syndrome (ACS) is a true emergency. Even with urgent fasciotomy, there is often muscle damage and need for further surgery. Although ACS is not uncommon, no validated classification system exists to aid in efficient and clear communication.

Management of high-energy blunt pelvic ring injuries: A retrospective cohort study evaluating an institutional protocol.

Introduction: High-energy blunt pelvic ring injuries with hemodynamic instability are complicated by a high mortality rate (up to 32%). There is no consensus on the best management strategy for these injuries. The aim of this study was to evaluate the high-energy blunt pelvic ring injury management protocol implemented in the authors' institution.

Acetabular Peri-Prosthetic Fractures-A Narrative Review.

Acetabular peri-prosthetic fractures are rare but their incidence is rising due to the increased prevalence of total hip arthroplasty, the increasing life expectancy and the growing functional demand of an ageing population, the incidence of primary total hip arthroplasty is increasing. They are either intra-operative or post-operative and have various aetiologies. Several factors such as implant stability, bone loss, remaining bone stock, fracture pattern, timing, age and co-morbidities of the patients must be considered for adequate treatment.

Association between open tibia fractures and acute compartment syndrome: A retrospective cohort study.

Background: Studies on the association of open tibia fractures and acute compartment syndrome (ACS) show confusing results, with some papers highlighting a positive association, and others failing to do so. The aim of this study was to determine if an open tibia fracture is at increased risk of ACS occurrence, when compared to a closed fracture.

Hypothesis: Skin injury in the setting of an open tibia fracture does not prevent from ACS occurrence, because the energy transmitted to the limb during trauma may lead to soft tissue lesions, including skin lacerations and ACS.

Osteosynthesis of non-displaced femoral neck fractures in the elderly population using the femoral neck system (FNS): short-term clinical and radiological outcomes.

Background: Femoral neck fractures (FNF) are frequent in the elderly population, and surgical management is indicated in the vast majority of cases. Osteosynthesis is an alternative to arthroplasty for non-displaced FNF. Triple screw construct (TS) and the dynamic hip screw system (DHS) are considered gold standards for osteosynthesis.

Inter- and intraobserver reliability assessment of the 2018 AO/OTA classification for high-energy pelvic ring injuries: A retrospective study.

Background: A fracture classification system should be a reliable and reproducible means of communication between different observers. It should be logical, comprehensible, and shouldn't contain an unmanageable number of categories. The aim of this study was to assess the intra- and interobserver agreement and reliability of the revised 2018 AO/OTA classification for high-energy pelvic ring injuries (PRI), at the level of the types, groups, subgroups and qualifications.

Incidence rate and topography of intra-pelvic arterial lesions associated with high-energy blunt pelvic ring injuries: a retrospective cohort study.

Background: The aim of this study was to determine the rate and topography of intra-pelvic arterial lesions associated with high-energy blunt pelvic ring injuries (PRI).

Methods: This retrospective cohort study was conducted in a level I trauma center serving 500,000 inhabitants. A total of 127 consecutive patients with high-energy blunt PRI were included between January 1st, 2014 and December 31st, 2017.

The Intraseptal Course of the Superficial Peroneal Nerve: An Anatomic Study.

Background: Anatomic and clinical studies show many variants of the superficial peroneal nerve (SPN) course and branching within the compartments and at the suprafascial layer. The anatomy of the transition zone from the compartment to the subcutaneous layer has been occasionally described in the literature, mainly in studies reporting the intraseptal SPN variant in 6.6% to 13.

Operatively treated ankle fractures in Switzerland, 2002-2012: epidemiology and associations between baseline characteristics and fracture types.

Background: Ankle fractures are common, and their incidence has been increasing. Previous epidemiological studies have been conducted in the US, Scandinavia, and Scotland. Our objectives were to provide a current epidemiological overview of operatively treated ankle fractures and to evaluate the influence of age, sex, lifestyle factors, and comorbidities on fracture types.

Fixation of AO-OTA 31-A1 and A2 trochanteric femur fractures using a sliding hip screw system: can we trust a two-hole side plate construct? A review of the literature.

Trochanteric femur fractures are frequently fixed with a four-hole side plate sliding hip screw device, but in recent decades two-hole side plates have been used in an attempt to minimize operative time, surgical dissection, blood loss and post-operative pain.The aim of this review was to determine whether two-hole sliding hip screw constructs are an acceptable option for fixation of AO-OTA 31-A1 and A2 trochanteric femur fractures.An electronic MEDLINE® database search was performed using PubMed®, and articles were included in this review if they were reporting historical, biomechanical, clinical or outcome data on trochanteric fracture fixation using a two-hole sliding hip screw device.

Clinical and radiographic predictors of acute compartment syndrome in the treatment of tibial shaft fractures: a retrospective cohort study.

Background: The purpose of this study was to evaluate the association between epidemiological, clinical and radiographic factors of patients with tibial shaft fractures and the occurrence of acute compartment syndrome.

Methods: 270 consecutive adult patients sustaining 273 tibial shaft fractures between January 2005 and December 2009 were included in this retrospective cohort study. The outcome measure was acute compartment syndrome.

A case report depicting patient's installation on the fracture table when an ankle spanning external fixator is already in place.

Background: Fractures of the proximal and diaphyseal femur are frequently internally fixed using a fracture table. Moreover, some femoral neck fractures may be treated with total hip arthroplasty using a direct anterior approach and a traction table. Fracture and traction tables both use a boot tightly fitted to the patient's foot in order to: 1) obtain fracture reduction by traction and adequate rotation exerted on the slightly abducted or adducted extremity; or 2) adequately expose the hip joint using traction, rotation and extension to implant total hip arthroplasty components.

False negative computed tomography scan due to pelvic binder in a patient with pelvic disruption: a case report and review of the literature.

Background: Pelvic binders are routinely used in the prehospital setting for stabilization of pelvic injuries in patients with trauma. Emergency department trauma management relies on primary and secondary survey assessment and imaging, most often computed tomography, in hemodynamically stable patients. Maintaining the pelvic binder in situ allows stabilization of pelvic injuries during imaging but may hinder the visualization of some pelvic lesions.

Primary hemiarthroplasty for treatment of unstable pertrochanteric femoral fractures (AO/OTA Type 31 A2.3) in elderly osteoporotic patients.

Introduction: The aim of this study was to prospectively analyze the role of primary hemiarthroplasty in unstable osteoporotic pertrochanteric fractures (AO/OTA Type 31 A2.3), with emphasis given to postoperative Functional Independent Measure (FIM) and Harris Hip Score (HHS).

Methods: Fifty-six consecutive patients (average age 78.

Syndesmosis reduction by computer-assisted orthopaedic surgery with navigation: Feasibility and accuracy in a cadaveric study.

Introduction: Syndesmotic disruption may be difficult to reduce and fix, and malreduction is associated with inferior outcomes. Intraoperative computed tomography (CT) can provide accurate assessment of syndesmotic reduction. We hypothesized that three-dimensional (3-D) computer-assisted orthopaedic surgery (CAOS) with navigation of syndesmotic reduction could avoid malreduction.

Radiation exposure using the O-arm surgical imaging system.

Purpose: This study was conducted to characterise the O-arm surgical imaging system in terms of patient organ doses and medical staff occupational exposure during three-dimensional thoracic spine and pelvic examinations.

Methods: An anthropomorphic phantom was used to evaluate absorbed organ doses during a three-dimensional thoracic spine scan and a three-dimensional pelvic scan with the O-arm. Staff occupational exposure was evaluated by constructing an ambient dose cartography of the operating theatre during a three-dimensional pelvic scan as well as using an anthropomorphic phantom to simulate the O-arm operator.
