Medialized Trochanteric Entry Nailing Is a Safe and Effective Method for High-Energy Subtrochanteric Femur Fracture Treatment.

Fixation of subtrochanteric femur fractures using intramedullary nails can provide high rates of osseous union. However, a lateral starting point or a medial trajectory can result in varus alignment, typically seen with trochanteric entry nails. Even with piriformis nails, medial comminution can result in secondary malalignment and varus.

The pivot fracture: an unusual tibial plateau fracture found in association with acute ACL injury.

Tibial plateau fractures are common fractures which are often associated with concurrent soft tissue injury and for which accurate preoperative diagnosis is important for development of an appropriate treatment plan and outcome prediction. Here, we present an extreme manifestation of the pivot shift phenomenon with an unusual tibial plateau fracture with flipped component not described by any existing tibial plateau fracture classification system and never reported previously in conjunction with an anterior cruciate ligament injury. We describe the utilization of advanced imaging not typically utilized in the management of tibial plateau fractures in combination with clinical suspicion to diagnose the associated soft tissue injuries and develop an appropriate management plan.

In-Hospital Morbidity and Mortality With Delays in Femoral Shaft Fracture Fixation.

Objectives: To investigate trends in the timing of femur fracture fixation in trauma centers in the United States, identify predictors for delayed treatment, and analyze the association of timing of fixation with in-hospital morbidity and mortality using data from the National Trauma Data Bank.

Methods: Patients with femoral shaft fractures treated from 2007 to 2015 were identified from the National Trauma Data Bank and grouped by timing of femur fixation: <24, 24-48 hours, and >48 hours after hospital presentation. The primary outcome measure was in-hospital postoperative mortality rate.

Kocher-Langenbeck Approach for Posterior Wall Acetabular Fractures.

Adequate surgical exposure is necessary for anatomical reduction and fixation of posterior wall acetabular fractures. This video demonstrates the Kocher-Langenbeck approach to the posterior acetabulum, as well as operative indications, surgical reduction and fixation techniques, and outcomes for posterior wall acetabular fractures.

Medialized Trochanteric Starting Point and Focused Lateral Endosteal Beak Reaming to Optimize Success of Intramedullary Nailing in Atypical Femur Fractures: A Technical Trick and Case Series.

Optimal intramedullary treatment of atypical femur fractures associated with bisphosphonate use requires avoidance of postoperative malreduction, particularly varus. This can be difficult to achieve, given the fracture location, errors with nail entry point, endosteal beaking, and underlying patient osteology, all of which can contribute to postoperative varus and predispose the patient to treatment failure. We present a surgical technique and clinical series of 10 patients emphasizing a medialized trochanteric nail entry point and preferential lateral endosteal reaming to secure a biologically and biomechanically favorable reduction and fixation.

Design: Retrospective case series.

Setting: Single academic Level I trauma center.

Outcomes of Proximal Humerus Fracture Open Reduction Internal Fixation with Concomitant Ipsilateral Shoulder Girdle Injuries: a Case Control Study.

Background: Proximal humerus fractures treated in the face of ipsilateral injuries to the shoulder girdle may be predisposed to worse clinical outcomes.

Questions/purposes: The purpose of this investigation was to examine outcomes of proximal humerus fractures treated with open reduction internal fixation (ORIF) using an endosteal augment in the presence of a concomitant shoulder girdle injury in comparison to isolated proximal humerus fractures treated with ORIF and endosteal augment.

Methods: A prospective database was used to identify proximal humerus fractures with ipsilateral shoulder girdle injuries (glenohumeral and acromioclavicular dislocation, fractures of the acromion, clavicle, scapula, or humeral diaphysis).

The Axillary View Typically Does Not Contribute to Decision Making in Care for Proximal Humeral Fractures.

Background: Convention dictates that an axillary view be obtained when evaluating proximal humerus fractures (PHF). However, the axillary view is frequently omitted because of pain and technical considerations. Furthermore, its diagnostic utility is unclear in this setting.

Dislocation is a risk factor for poor outcome after supination external rotation type ankle fractures.

Introduction: Ankle fractures are one of the most common fractures requiring surgical treatment. Ankle fracture-dislocations are significant injuries to the osseous and soft tissue envelope, but studies focused on the effect of dislocation on radiographic and functional outcomes are lacking. The objective of this study was to evaluate the effect of dislocations on postoperative outcomes in SER IV ankle fracture patients.

Extensor Mechanism Injuries of the Knee: Demographic Characteristics and Comorbidities from a Review of 726 Patient Records.

Manual Stress Ankle Radiography Has Poor Ability to Predict Deep Deltoid Ligament Integrity in a Supination External Rotation Fracture Cohort.

Stress ankle radiographs are routinely performed to determine deep deltoid ligament integrity in supination external rotation (SER) ankle fractures. However, variability is present in the published data regarding what medial clear space (MCS) value constitutes a positive result. The purposes of the present study were to evaluate the diagnostic accuracy of different MCS cutoff values and determine whether this clinical test could accurately discriminate between patients with and without a deep deltoid ligament disruption.

The Impact of Three-Dimensional CT Imaging on Intraobserver and Interobserver Reliability of Proximal Humeral Fracture Classifications and Treatment Recommendations.

Background: The classification systems for fractures of the proximal part of the humerus provide low interobserver and intraobserver reliability when radiographs or two-dimensional computed tomography scans are used. The purpose of this investigation was to determine whether the use of three-dimensional computed tomography scans could improve interobserver and intraobserver reliability of AO/OTA (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association) and Neer classifications and treatment recommendations.

Methods: Two trauma surgeons, one shoulder surgeon, two senior orthopaedic residents, and two junior orthopaedic residents reviewed the radiographs and two and three-dimensional computed tomography scans of forty fractures of the proximal part of the humerus.

Evaluation of Lauge-Hansen designation of Weber C fractures.

Associations between Weber C ankle fractures and pronation external rotation (PER) injuries of the Lauge-Hansen classification have often been incorrectly correlated. The purpose of the present study was to evaluate the Lauge-Hansen designation of Weber C fractures by establishing the proportion of Weber C fractures that are supination external rotation (SER), supination adduction (SA), pronation abduction (PA), PER, and hyperplantarflexion variant fractures. A clinical database of operative ankle fractures treated by the senior author (D.

Intramedullary allograft fibula as a reduction and fixation tool for treatment of complex proximal humerus fractures with diaphyseal extension.

In this study, we present a novel technique for reduction and fixation of complex, unstable proximal humerus fractures with diaphyseal extension with the assistance of fibula allograft. We treated 14 patients using this technique since 2009 and found that it improves the reduction and enhances fixation while making the surgical procedure technically more manageable, and allows for early postoperative motion. In the first part of this study, we describe in detail the indications and surgical technique applied to these fractures.
