To define the incidence, risk factors, and anatomic location of articular malreductions in operatively treated lateral tibial plateau fractures.Prospective Cohort Study.Academic Level 1 Trauma Centre.Study subjects were patients entered into a prospective cohort study fractures.Surgical fixation fractures postoperative computed tomographies (CTs).The primary outcome was incidence malreduction. Secondary outcomes included factors for malreduction descriptive analysis location.Sixty-five CTs...
Background and purpose Bridging external fixation is used more frequently than non‐bridging in the management of unstable distal radius fractures, despite evidence from randomized controlled trials better outcome with latter technique. This study was designed to investigate generalizability technique fixation, define indications for use each their complications.
• An attempt was made to evaluate the potential advantages of chemotherapy in treatment 62 patients with glioblastoma. Twenty-four received adjuvant nitrosourea carmustine (BCNU), lomustine (CCNU), or semustine (methyl CCNU) addition surgery and radiotherapy. Thirty-three were involved a controlled, prospective, randomly allocated study. Quality quantity survival not prolonged who chemotherapy. Age greater than 64 years, severe postoperative neurological deficit, onset symptoms less 12...
To determine whether single or double screw (DS) fixation of medial malleolar fractures results in better long-term health outcomes.Randomized clinical trial; sealed envelope technique.Level 1 Trauma Hospital at University Calgary, Canada.One hundred forty patients were randomized to receive either 2 screws reduce a fracture. Thirteen excluded because loss follow-up (n = 127).Surgical the fracture was performed using stainless steel screws.Primary outcome comparison physical functioning...
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) has been extensively evaluated in groups of patients with osteoarthritis, yet not a femoral neck fracture. This study aimed to determine the reliability, construct validity, responsiveness WOMAC compared Short Form-12 (SF-12) EuroQol 5D (EQ-5D) questionnaires for assessment elderly fracture.Reliability was tested by assessing Cronbach alpha. Construct validity determined Pearson correlation coefficient. Change scores...
<h3>Background:</h3> Venous thromboembolism (VTE) is the second most common complication after hip fracture surgery. We used thrombelastography (TEG), a wholeblood, point-of-care test that can provide an overview of clotting process, to determine duration hypercoagulability <h3>Methods:</h3> In this prospective study, consecutive patients aged 51 years or more with fractures (trochanteric region neck) amenable surgical treatment who presented emergency department were eligible for enrolment....
Dual-plate constructs have become an increasingly common fixation technique for midshaft clavicle fractures and typically involve the use of mini-fragment plates. The goal this is to reduce plate prominence implant irritation. However, limited biomechanical data exist these lower-profile constructs. study aim was compare dual orthogonal plating with small-fragment plates noninferiority determine if optimal configuration could be identified using a cadaveric model.Twenty-four clavicles were...
In surgery, preoperative handover of surgical trauma patients is a process that must be made as safe possible. We sought to determine vital clinical information transferred between patient care teams and develop standardized checklist.We conducted small-group interviews about handover. Based on this information, we created questionnaire gather perspectives from all Canadian Orthopaedic Association (COA) members which topics they felt would most important checklist. analyzed the responses...
To assess fragment micromotion in three fracture fixation constructs 18 composite femur models were sectioned to create AO-C3 fractures and fixed using the Less Invasive Stabilization System (LISS), Dynamic Condylar Screw (DCS), or Buttress Plate (CBP). Tantalum beads attached each fragment. The tested for permanent deformation after cyclical loading (amplitude = 242.2N) elastic during static with 490.5N. Radiographs taken before then unloading determine deformation. We used RSA quantify six...
The sliding hip screw device (SHSD) is a commonly used implant to treat extracapsular neck of femur fractures. most common described mode failure femoral head cut out. Mechanical rare and when it occurs normally involves the plate rather that screw. Failure itself uncommon few cases have been reported in literature. mechanical usually multiple-cycle, low stress fatigue than low-cycle, high as result nonunion fracture. This case demonstrates cycle, SHS some potential causes for this are discussed.

The surgical reduction of intra-articular olecranon fractures is judged primarily on the lateral elbow radiograph, as orthogonal imaging articular surface not obtainable. We sought to determine surgeon accuracy in identifying malreductions radiograph.Six human fresh-frozen cadaveric specimens were sagittally sectioned 5-mm increments after dissection, preservation soft tissue envelope, and rigid fixation an external fixator. Three patterns central malreduction created each using a ruler bone...
Lesions of the meniscocapsular junction and meniscotibial ligament (MTL) posterior horn medial meniscus are common with knee ligamentous injuries associated residual rotational instability if left untreated. MTL avulsion from its tibial attachment has never been described among different types disruptions so far. Both diagnosis treatment such an injury can be challenging. This article describes a detailed technique proposes algorithm to appropriate management this rare injury.
Isolated fractures of the ulnar diaphysis are uncommon, occurring at a rate 0.02 to 0.04 per 1,000 cases. Despite their infrequency, these commonly give rise complications, such as nonunion, limited forearm pronation and supination, restricted elbow range motion, radioulnar synostosis, prolonged pain. Treatment options for this injury remain topic debate, with research available no consensus on optimal approach. Therefore, trial aims compare clinical, radiological, functional outcomes two...
In older adults facing knee arthroplasty, the ability to resume downhill skiing postoperatively is unclear. This study aimed determine perspectives of Alberta orthopedic surgeons and senior residents regarding after total arthroplasty (TKA) or unicompartmental (UKA).In May 2019, a Web-based survey was sent through Orthopaedic Society poll performing (postgraduate year 4 5) in permissibility TKA UKA. The also elicited information under which conditions restrictions, if any, would allow...
De façon quelque peu surprenante, l’Irlande du XIIIe siècle fut liée aux événements survenus en Languedoc, à travers un réseau de connexions politiques. Au centre ces péripéties figure Hugues II Lacy, comte d’Ulster. À la suite son expulsion d’Irlande par Jean sans Terre, 1210, demeura exil sur le continent pendant treize ans avant d’envahir une partie Meath et comté d’Ulster autrefois sien. Grâce l’analyse carrière d’Hugues Lacy ses années d’exil, cet article insiste rôle capital dans...
Case: We present a case of acute disseminated intravascular coagulation (DIC) after prophylactic femoral intramedullary stabilization in patient with metastatic prostate cancer. Preoperative international normalized ratio 1.4 was attributed to malnutrition, and the not medically optimized. DIC developed 1 hour postoperatively managed blood product resuscitation. At 4-month follow-up, presented bilateral pulmonary emboli transitioned palliative care. Conclusions: patients bone disease is rare...
