Plate fixation of comminuted bicondylar tibial plateau fractures remains controversial. This retrospective study was performed to evaluate the perioperative results and functional outcomes medial lateral plate stabilization, through anterolateral posteromedial surgical approaches, fractures.Over a seventy-seven-month period, eighty-three AO/OTA type-41-C3 were treated with two exposures. Injury radiographs rank-ordered according fracture severity. Immediate biplanar postoperative evaluated...
The transolecranon exposure for distal humerus fractures is a suggested technique improving articular visualization, allowing accurate reduction. Significant osteotomy complications such as nonunion and implant prominence have prompted recommendations alternate exposures. purposes of this study are to present the techniques olecranon management fractures, evaluate adequacy humeral reductions.Retrospective review.Urban level-1 University trauma center.One hundred fourteen skeletally mature...
Background: Plate fixation of comminuted bicondylar tibial plateau fractures remains controversial. This retrospective study was performed to evaluate the perioperative results and functional outcomes medial lateral plate stabilization, through anterolateral posteromedial surgical approaches, fractures. Methods: Over a seventy-seven-month period, eighty-three AO/OTA type-41-C3 were treated with two exposures. Injury radiographs rank-ordered according fracture severity. Immediate biplanar...
To compare long-term health outcome of Sanders type IV calcaneal fractures treated with open reduction and internal fixation (ORIF) versus ORIF plus primary subtalar arthrodesis (PSTA).Randomized prospective multicenter trial.Four Level 1 trauma hospitals in Canada.Thirty-one patients 31 displaced intraarticular fractures.Seventeen were a standard protocol involving lateral approach for ORIF. Fourteen + PSTA.Health outcomes assessed 4 validated instruments: (1) the Short Form 36 version 2...
To describe the associated injuries, demographic distribution, and management of patients sustaining open clavicle fractures.Retrospective case series.A single level-1 trauma center.Twenty with fractures were identified from a prospectively collected orthopaedic registry.All managed surgical irrigation debridement or without internal fixation.Thirteen (65%) had closed head injury. Fifteen (75%) significant pulmonary In that group, there 10 who pneumothorax (7 bilateral). Additionally, 12 rib...
Abstract Periprosthetic osteolysis involves osteoclast activation by wear particulates and their exposure to mechanical perturbation through shear forces generated periprosthetic fluid as well interface micromotion. This study aimed determine the interactions between particulates, stimulation, osteoclasts. In static cultures, increased differentiation. Addition of neutralizing antibodies RANKL (receptor activator nuclear factor kappa ligand) inhibited particle‐induced increase in numbers....
Objectives: The goal of this study was to describe current opinions orthopaedic trauma experts regarding acute compartment syndrome (ACS). Design: Web-based survey. Participants: Active Orthopaedic Trauma Association (OTA) members. Methods: A 25-item web-based questionnaire advertised active members the OTA. Using a cross-sectional survey design, we evaluated perceived importance ACS, as well preferences in diagnosis and treatment. Results: One hundred thirty-nine 596 OTA (23%) completed ACS...
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...
Objective: To determine if geriatric intertrochanteric hip fracture patients achieve equivalent postoperative functional status after management with either a short (180-200 mm) or long (260-460 InterTAN intramedullary device. Design: Retrospective review of prospective randomized control trial. Setting: Four Level I Trauma Centers. Patients/Participants: One hundred eight OTA/AO classification 31A-1 and 31A-2 fractures were included in the study. Intervention: Internal fixation using an IT...
Abstract Open fractures with soft-tissue loss remain challenging injuries to treat. These often high-energy are at a higher risk of delayed healing and much infection than open less significant injury. The initial management the wound, flap coverage options, timing definitive all areas controversy, which will be discussed in this article.
Pertrochanteric femoral fractures are routinely treated with cephalomedullary nailing, good success. In the event of nonunion, implant fatigue failure may occur. The Trigen InterTAN system (Smith & Nephew, Memphis, TN) features 2 integrated screws for improved rotational stability proximal segment. inferior compression screw prevents rotation larger, superior lag screw. breakage, retained portion will prevent from being rotated to permit extraction. We present a case broken nail as well...
Objectives: To compare outcomes in elderly patients with intertrochanteric hip fractures treated either the sliding screw (SHS) or InterTAN intramedullary device (IT). Design: Prospective, randomized, multicenter clinical trial. Setting: Five level 1 trauma centers. Patients: Two hundred forty-nine 55 years of age older AO/OTA 31A1 (43) and OA/OTA 31A2 (206) were prospectively enrolled followed for 12 months. Intervention: Computer generated randomization to IT (n = 123) SHS 126). Main...
