Objective: This study was designed to evaluate the postimpact response of articular cartilage in rabbit knee after a single traumatic episode. Design: A novel servo-controlled Rabbit Impact Test System (RITS) developed apply well-defined trauma femoral condyle knee. The RITS first used an vitro determine appropriate stress cause damage without bone fracture. Viable knees (n = 18) were impacted with stresses 15 50 MPa at rate 420 MPa/s, latter corresponding joint impact rates commonly seen...
To assess the accuracy of a new radiographic measurement distal tibia and fibula on lateral view ankle in normal adults: anteroposterior tibiofibular (APTF) ratio.Thirty adults without history trauma or disease were included. Bilateral ankles x-rayed with true ankle. A line from anterior tibial physis scar to posterior cortex, passing by intersection was drawn. The APTF ratio calculated as segment segment. measurements done 3 independent evaluators. Intra- interobserver reliability obtained...
Extremity fractures are common, and most managed operatively; however, despite successful reduction, up to half of patients report persistent post-surgical pain. Furthermore, psychological factors such as stress, distress, anxiety, depression, catastrophizing, fear-avoidance behaviors have been associated with the development chronic The purpose this pilot study was examine feasibility a randomized controlled trial determine effect in-person cognitive behavioral therapy (CBT) vs. usual care...
Outcomes following surgery to operatively manage extremity fractures are variable, and up two-thirds of patients report chronic post-surgical pain. Preliminary evidence suggests that psychotherapy directed at improving coping skills reducing somatic vigilance may improve outcomes among fracture patients. The objective this pilot study was test the feasibility acceptability a randomized controlled trial comparing an online cognitive behavioural therapy (CBT) program versus usual care in with...
This propensity-matched cohort study aimed to determine if adding adductor canal block (ACB) local infiltration analgesia (LIA) reduces immediate postoperative opioid use in ACL reconstruction and assess variations based on graft type. retrospective analyzed reconstructions performed from 2019 2021. Patients were included they received either LIA alone or a combination of ACB. demographic surgical factors, perioperative consumption was assessed. Subgroup analysis conducted autograft type...
OBJECTIVES: To evaluate a new compartment pressure monitor reporting continuous pressures and its contribution to Acute Compartment Syndrome (ACS) diagnosis. METHODS: Design : Multicenter, non-randomized, prospective study. Setting: Six Level-I Trauma Centers. Patient Selection Criteria: Enrolled were patients with acute long bone fractures (OTA 11-13, 2R, 2U, 31-33, 41-43) where the Micro Electric Mechanical Sensor (MEMS) device was inserted either pre- or post-operatively into most likely...
Proximal humerus fractures are the third most common fracture in elderly population and expected to increase due aging population. Surgical fixation with locking plate technology has increased over last decade despite a lack of proven superiority literature. Three previous randomized controlled trials have not shown difference patient-centered outcomes when comparing non-operative treatment open reduction internal fixation. Low patient enrollment other methodological concerns however limit...
➤ A preoperative computed tomography scan may be considered to improve surgical planning, as secondary fracture lines are poorly visualized on radiographs. Oblique internal and external rotation fluoroscopic views used intraoperatively fully evaluate the medial lateral facet articular reduction if direct assessment by visualization or palpation is not completed. Partial patellectomy for inferior pole fractures should avoided, bone-preserving procedures recommended. arthrotomy of...
Negative-pressure wound therapy (NPWT) can improve fasciotomy closure, but its effects on skeletal muscle are largely unknown. The purpose of this study was to evaluate NPWT after for compartment syndrome in an animal model and assess regional variability fiber regeneration.Compartment induced the hindlimb twenty-two adult female pigs with use a continuous intracompartmental serum-infusion model. Fasciotomy performed six hours, animals were randomized receive either wet-to-dry gauze...
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...

There have been no studies assessing the optimal biomechanical tension of suture button constructs. The purpose this study was to assess tensioning fixation and its ability maintain reduction under loaded conditions using a stress computed tomography (CT) model.Ten cadaveric lower limbs disarticulated at knee were used. placed in modified ankle load frame that allowed for application sustained torsional axial or combined torsional/axial loads. syndesmosis deep deltoid ligaments complex...
Chronic, non-cancer pain affects approximately 20-30% of the population in North America, Europe, and Australia, with surgery trauma frequently cited as inciting events. Prospective studies fracture patients have demonstrated an association between somatic pre-occupation, poor coping, low recovery expectations following persistent pain, functional limitations, lower rates return to work. Psychological interventions, such cognitive behavioural therapy (CBT), that are designed modify unhelpful...
