Interdisciplinary strategies to prevent long-term and detrimental opioid use following trauma: a stakeholder consensus study.

Objective: Prolonged opioid use is common following traumatic injuries. Although preventive strategies have been recommended, the evidence supporting their use is low. The objectives of this study were to select interdisciplinary strategies to prevent long-term, detrimental opioid use in trauma patients for further evaluation and to identify implementation considerations.

Comparing external and internal validation methods in correcting outcome misclassification bias in logistic regression: A simulation study and application to the case of postsurgical venous thromboembolism following total hip and knee arthroplasty.

Purpose: We assessed the validity of postsurgery venous thromboembolism (VTE) diagnoses identified from administrative databases and compared Bayesian and multiple imputation (MI) approaches in correcting for outcome misclassification in logistic regression models.

Methods: Sensitivity and specificity of postsurgery VTE among patients undergoing total hip or knee replacement (THR/TKR) were assessed against chart review in six Montreal hospitals in 2009 to 2010. Administrative data on all THR/TKR Quebec patients in 2009 to 2010 were obtained.

Phonomyography as a non-invasive continuous monitoring technique for muscle ischemia in an experimental model of acute compartment syndrome.

Background: In acute compartment syndrome (ACS), clinicians have difficulty diagnosing muscle ischemia provoked by increased intra-compartmental pressure in a timely and non-invasive manner. Phonomyography records the acoustic signal produced by muscle contraction. We hypothesize that alterations in muscle contraction caused by muscle ischemia can be detected with phonomyography, serving as a potential non-invasive technique in the detection of ACS.

Review of 5.5 Years' Experience Using E-mail-Based Telemedicine to Deliver Orthopedic Care to Remote Communities.

Introduction: The use of e-mail-based telemedicine has been demonstrated as an effective and low-cost way of delivering healthcare to patients in remote areas who have limited access to medical services. We established a novel teleorthopedic service for a catchment area encompassing 972,000 km using a commercial off-the-shelf e-mail application. Before the implementation of this program, patients with acute orthopedic injuries were required to travel by air up to 1,900 km for evaluation by an orthopedic surgeon.

Short-term mortality associated with failure to receive home care after hemiarthroplasty.

Background: Hemiarthroplasty is often the treatment of choice after hip fracture, particularly in frail elderly patients. Such patients may benefit from home care after discharge. We assessed factors associated with the receipt of home care and evaluated the risk of death within three months after discharge.

Efficacy of different fixation devices in maintaining an initial reduction for surgically managed distal radius fractures.

Background: Fracture of the distal radius is a common injury. Many treatment options exist for the surgical management of extra-articular and intra-articular distal radius fractures. The best method of treatment for these fractures remains controversial.

Postdischarge thromboprophylaxis and mortality risk after hip-or knee-replacement surgery.

Background: Patients undergoing hip or knee replacement are at high risk of developing a postoperative venous thromboembolism even after discharge from hospital. We sought to identify hospital and patient characteristics associated with receiving thromboprophylaxis after discharge and to compare the risk of short-term mortality among those who did or did not receive thromboprophylaxis.

Methods: We conducted a retrospective cohort study using system-wide hospital discharge summary records, physician billing information, medication reimbursement claims and demographic records.

Percutaneous insertion of a proximal humeral locking plate: an anatomic study.

This cadaveric study sought to evaluate the feasibility of applying a locking proximal humerus plate with a novel minimally invasive technique. A unique pre-contoured locking plate was placed on cadaveric proximal humeri through a described minimally invasive approach. Proximity of the plate and screws to the axillary nerve and their respective surgical tracks were quantified.

Anterior reduction for cervical spine dislocation.

Study Design: Retrospective analysis of a prospectively followed cohort.

Objective: Long-term evaluation of patients with anterior stabilization for dislocations of the cervical spine.

Setting: Level 1 trauma center.

Knee dislocations: experience at the Hôpital du Sacré-Coeur de Montréal.

Introduction: Although many options exist for ligament reconstruction in knee dislocations, the optimal treatment remains controversial. Allografts and autografts have both been used to reconstruct the cruciate ligaments. We present the results of reconstruction using artificial ligaments at Hôpital du Sacré-Coeur in Montréal.
