Objectives: To establish a laboratory model of implant cutout, which can evaluate the effect design on cutout resistance in clinically realistic "worst case" scenario. Setting: Orthopaedic biomechanics laboratory. Design: Implant was simulated an unstable pertrochanteric fracture model, accounted for dynamic loading, osteoporotic bone, and defined offset. For characterization, lag screw human cadaveric specimens polyurethane foam surrogates. Subsequently, surrogates were used to determine...
The incidence of humeral shaft fractures has been increasing over time. This represents a growing public health concern in climate cost containment. purpose this study is to analyze national trends surgical management and determine factors predictive intervention.Humeral were identified by the International Classification Diseases, Ninth Revision, Clinical Modification codes 812.21 812.31 United States Nationwide Inpatient Sample from 2002 2011. Open reduction internal fixation (ORIF) was...
The 2 main forms of treatment for distal femur fractures are locked lateral plating and retrograde nailing. goal this trial was to determine whether there significant differences in outcomes between these treatment. Multicenter randomized controlled trial. Twenty academic trauma centers. One hundred sixty patients with were enrolled. twenty-six followed 12 months. Patients 62 cases intramedullary nailing 64 cases. Lateral or Functional scoring including Short Musculoskeletal Assessment,...
Intramedullary nailing of femoral shaft fracture can result in inadvertent malalignment. Malrotation is the most common cause deformity, but it underrecognized, part because difficulty accurately assessing rotation as well variation that exists normal anatomy. The consequences malrotation are not completely understood. However, initial biomechanical studies suggest causes a substantial change load bearing affected extremity. Clinical examination, fluoroscopy, and ultrasonography useful...
To determine whether interobserver technical variations and errors in the measurement of compartment pressures may affect accuracy.Four above-knee cadaveric specimens were used to create a consistent model lower leg syndrome. Thirty-eight physicians examined limbs measured 4 using Intra-Compartmental Pressure Monitor (Stryker Orthopaedics). They observed for correct assembly use monitor. Measurements obtained compared with known pressures.Of total number measurements, 31% made technique, 39%...
Axial stiffness is a critical mechanical parameter in fracture plating. Standard locked plates allow minimal opportunities for alteration, and current methods are arbitrary may lead to mismatch between the implant bone. Milling near cortex into slot allows an increase translation of screw shaft at cortex. The purpose this proof concept study was determine effects slots on their ability maintain fixation locking under cyclic loading.Using segments fourth-generation synthetic diaphyseal bone,...
We believe that a certain subset of surgical ankle fracture patients can be made weight-bearing as tolerated immediately following surgery. Immediate (IWBAT) allows to return ambulation and activities daily living faster may facilitate rehabilitation. A prospectively gathered orthopaedic trauma database at Level 1 center was reviewed retrospectively identify who had ORIF after unstable injuries treated by the senior author. Patients were excluded if they not IWBAT based on specific criteria...
The Journal of Orthopaedic Research, a publication the Research Society (ORS), is forum for rapid high quality reports new information on full spectrum orthopaedic research, including life sciences, engineering, translational, and clinical studies.
Biomechanical testing of fracture fixation implants is crucial in preclinical evaluation and comparing new devices with standard devices. Many variables must be considered when planning implementing a biomechanical vitro experiment. The type test selected (eg, load-to-failure, stiffness, cyclic fatigue) depends on the research question being asked. For example, fatigue attempts to replicate clinical situations; thus, load magnitudes directions number cycles should decided accordingly. Most...
In case of implant associated infection, preservation is with high failure rates.Therefore, a removal or exchange the most often mandatory for treatment success.Alternatively, under certain conditions, local antibiotic delivery can be applied -preserving implant, using example calcium sulphate as resorbable carrier.In this work, third-body wear on total hip prostheses caused by particles was tested in simulator.Inlays made ultra-high-molecular-weight polyethylene (UHMWPE) and cross-linked...
Proximal humerus fractures are relatively common, with treatment dependent on fracture-specific, patient-specific, and surgeon-specific factors. This study sought to identify preferences among shoulder specialists orthopedic traumatologists in the of proximal fractures. An anonymous Internet survey fellowship-trained surgeons was conducted radiographs select computed tomography images 15 unique displaced Participants were asked classify each case according Neer criteria choose management...
Abstract. Introduction: Fracture-related infection (FRI) is a common complication associated with orthopaedic fracture care. Diagnosing these complications in the preoperative setting difficult. Platelets are known acute phase reactant indices that change accordance and inflammation. The purpose of our study was to assess diagnostic utility platelet at assessing FRI.Methods: A retrospective review performed for all patients who underwent revision surgery nonunion between 2013 2018....
Summary: We present the case of an 86-year-old woman who suffered full-thickness soft tissue loss secondary to degloving injury lower left limb, resulting in exposed tibia. This patient underwent drilling create artificial fenestrations cortical bone followed by placement Integra dermal regeneration template. The technique expose underlying vasculature has not previously been described its relationship with templates large injuries limb. enabled us perform earlier skin grafting and...
Fracture nonunion remains a devastating complication and may occur for several reasons, though the microbial contribution poorly estimated. Next-generation sequencing (NGS) techniques, including 16S rRNA gene profiling, are capable of rapid bacterial detection within clinical specimens. Nonunion cases harbor microbes that escape by conventional culture methods contribute to persistence. Our aim was investigate application NGS pathogen diagnosis.In this prospective multicenter study, samples...
Previous mechanical studies concerning cut-out of lag screws for pertrochanteric hip fractures have relied on static or dynamic uniaxial loading regimens to induce construct failure by varus collapse and superior cut-out. However, the is loaded in a multiplanar, manner during normal gait. We designed implant performance simulator (HIPS) system evaluate screw under multiplanar representative Five surrogate fracture specimens with fixation were up 20,000 cycles using biaxial rocking motion...
Ankle fractures are among the most common injuries requiring operative management. Implant choices include one-third tubular plates and anatomically precontoured plates. Although cadaveric studies have not revealed biomechanical differences between various plate constructs, there substantial cost differences. This study sought to characterize economic implications of implant choice. A retrospective review was undertaken 201 consecutive patients with operatively treated OTA type 44B 44C...
The purpose of this study was to examine the efficacy a fluoroscopically guided hip capsulotomy.Ten fresh-frozen paired cadaveric hips were injected under fluoroscopic guidance with saline sufficient generate an intra-articular pressure greater than 58 mmHg. monitored continuously using percutaneous transducer. A limited lateral approach proximal femur performed by one two senior orthopaedic trauma surgeons. Using scalpel guidance, each surgeon made attempt at anterior capsulotomy. Changes...
