Background. Combat is associated with high-energy explosive injuries, often resulting in open tibial fractures complicated by nonunion and infection. We characterize the infections seen conjunction combat-associated type III fractures.
Despite the widespread use of systemic antibiotics to prevent infections in surgically treated patients with fracture, high rates surgical site infection persist.To examine effect intrawound vancomycin powder reducing deep infections.This open-label randomized clinical trial enrolled adult an operatively tibial plateau or pilon fracture who met criteria for a risk from January 1, 2015, through June 30, 2017, 12 months follow-up (final assessments completed April 2018) at 36 US trauma...
Type III open tibia fractures are common combat injuries. The purpose of the study was to evaluate effect injury characteristics and surveillance cultures on outcomes in combat-related severe fractures. We conducted a retrospective all Gustilo Anderson (G/A) type diaphyseal treated at our centers between March 2003 September 2007. One hundred ninety-two Operation Iraqi Freedom/Operation Enduring Freedom military personnel with 213 tibial shaft were identified. Fifty-seven extremities (27%)...
Sarcopenia is a condition of clinically relevant loss muscle mass and function. Acetabular fractures in elderly patients are common difficult to treat. This study aimed determine if sarcopenia with acetabular correlates lower-energy mechanisms injury, higher rates complications, mortality than normal mass.The Rhode Island Hospital Trauma Database was queried for who were ≥60 years age from 2005 2014 using the International Classification Diseases, Ninth Revision, code closed fracture, 808.0....
Background: The incidence of ankle fractures is increasing in the geriatric population, and several studies suggest them to be third most common extremity fracture this age group. Previous work has reflected relatively low complication rates during operative treatment. Little known, however, about association between these injuries overall mortality, nor whether intervention any effect on mortality. We hypothesized that would correlated with an elevated mortality rate associated a reduced...
Military, governmental, and civilian agencies routinely respond to disasters around the world, including large-scale mass casualty events such as earthquake in Pakistan 2005, Hurricane Katrina United States Haiti 2010. Potential exists for improved coordination of medical response between military sectors creation a planned practiced interface. Disaster preparedness could be enhanced with more robust disaster education responders; database precredentialed, precertified specialists;...
Femoral and tibial shaft fractures are common injuries in the United States. Since their introduction, reamed intramedullary nails have become treatment of choice for most these fractures. However, delayed union nonunion can complicate up to 10% patients. Removal interlocking screws, or dynamization, promote fracture healing cases nonunion. The efficacy nail dynamization has been reported range from 19% 82%. This study was conducted evaluate identify factors associated with its success...
Background: Severe upper-extremity injuries account for almost one-half of all extremity trauma in recent conflicts the Global War on Terror. Few long-term outcomes studies address severe combat-related injuries. This study’s objective was to describe functional amputation compared with those limb salvage Terror veterans who sustained Limb hypothesized result better arm and hand function scores, overall status, quality life, similar pain interference. Methods: retrospective cohort study...
Objectives: To compare the static and dynamic mechanical properties of a modified crossed cannulated screw (CS) configuration, inverted triangle (IT) compression hip (CHS) with derotation in Pauwels type III femoral neck fractures. Methods: Thirty synthetic femora were divided into 3 groups, vertical osteotomies made. Ten osteotomized fixed CS 10 parallel screws an IT remaining CHS construct. All groups tested using cyclic (up to 15,000 load cycles) axial loading protocol, survivors...
Background: The purpose of this study was to examine the incidence adverse events in elderly patients who required inpatient admission after sustaining an ankle fracture and consider these data relation geriatric hip other patient admissions. Methods: A retrospective cohort admitted with fracture, a or any diagnosis performed Medicare Part database for 2008. primary outcome measure one-year mortality rate, examined multivariate analysis factoring both age preexisting comorbidity. Secondary...
To evaluate the effect of tourniquet use during anterior cruciate ligament reconstruction, 40 consecutive pa tients were randomized into two groups: Group I (tour niquet) and II (no tourniquet). Preoperative eval uation included electromyography, measurement thigh calf girth, determination serum creat inine phosphokinase levels. Initial postoperative uations serial creatinine de terminations. At 1 6 months postoperatively, electromyographic examination was repeated girth measurements...
Bone infection remains a formidable challenge to the medical field. The goal of current study is evaluate antibacterial coatings in vitro and develop large animal model assess coated bone implants. A novel coating consisting titanium oxide siloxane polymer doped with silver was created by metal-organic methods. tested using rapid screening techniques determine compositions which inhibited Staphylococcus aureus growth, while not affecting osteoblast viability. then applied intramedullary...
With rising rates of obesity in the United States, burden knee dislocations this population remains unknown. This national epidemiologic study was designed to analyze association with closed dislocation and vascular complications. Retrospective cohort study. The deidentified Nationwide Inpatient Sample database used access US inpatient data from 2000 2012. Patients noncongenital were included. Examined variables included patient age, sex, injury, status. Outcome measures hospital length...
Background The purpose of this study was to determine whether the acute bone grafting diaphyseal forearm fractures decreases incidence nonunion and reduces time union. Although traditional treatment comminuted radius and/or ulnar shaft involves graft, a recent report called into question practice. Patients A database search used identify all presenting an urban Level I trauma center between 1988 1996. All fractures, as well Monteggia Galeazzi fracture-dislocations, in patients with closed...
Many conditions of the foot have been related to pressure maldistribution. Alteration plantar through improvements shoe fit, orthoses, and surgery are presumed correct We evaluated 10 volunteers with normal, asymptomatic feet. With use an ultrathin in-shoe sensor, pressures were measured within at shoe/foot interface. Test included three pad types: large foam, felt, small felt. They in positions: normal (at metatarsal head base) 5 mm proximal distal position. When compared control condition...
Composite flexor-tendon grafts (both tendons with sheath and pulleys intact) were performed in adult chickens comparing fresh autografts allografts stored 1:5,000 merthiolate under refrigeration for two months. The gross microscopic findings assessed one week to year after transfer. somewhat slower heal but otherwise differed little from the autografts, readily accepted eventually only minor adhesions between grafted tendon sheath.
We studied patients with combat-related injuries that required delayed amputation at least 4 months after the initial injury due to dysfunction, persistent pain, and patient desires. Late amputations were performed 22 times in (21 men, 1 woman) since 2003. Fourteen underwent transtibial amputation, 5 transfemoral amputations, knee disarticulation, 2 transradial amputations. The primary indications for late neurologic dysfunction 6 patients, or recurrent infection 6, neurogenic pain 3,...
Terrorist blasts and landmine injuries have become more common in the past several decades generating thousands of casualties. Preventive prognostic measures are limited by lack knowledge these complex events. Previous blast research has focused on primary that involve lung, despite musculoskeletal being most common. Through use instrumented cadavers, Hybrid III test dummies, other surrogates, unique models events been created. The investigations studied effectiveness antimine footwear,...
