Locked plating has become a standard method to treat supracondylar femur fractures. Emerging evidence indicates that this of treatment is associated with modest failure rates. The goals study were determine risk factors for complications and provide technical recommendations locked fractures.Retrospective review.Three level I or II trauma centers.Three hundred twenty-six patients 335 distal fractures (OTA 33A C, 33% open) treated lateral plates studied. average patient age was 57 years...
To quantify the obliquity and dimensions of upper second sacral segment iliosacral screw safe zones to determine differences between normal dysmorphic morphology.Retrospective cohort.University Level I trauma center.Fifty patients with pelvic computed tomography scans.All sacra were characterized as or based on plain radiographs previously described criteria. Multiple scan reconstructions viewed manipulated simultaneously 6 degrees freedom allow for custom visualization in any plane.In each...
Background: Fractures of the femoral shaft are common and have potentially serious consequences in patients with multiple injuries. The appropriate timing fracture repair is controversial. purpose present study was to assess effect internal fixation on mortality multisystem trauma. Methods: We performed a retrospective cohort use data from public private trauma centers throughout United States that were reported National Trauma Data Bank (version 5.0 for 2000 through 2004). included 3069...
Introduction Exposure to nature may reduce stress in low-income parents. This prospective randomized trial compares the effect of a physician's counseling about with or without facilitated group outings on and other outcomes among Materials methods Parents patients aged 4–18 years at clinic serving families were supported park prescription versus independent 2:1 ratio. both groups received physician nature, maps local parks, journal, pedometer. The additional phone text reminders attend...
Background: Upper sacral segment dysplasia increases the risk of cortical perforation during iliosacral screw insertion. Dysmorphic sacra have narrow and angled upper osseous corridors. However, there is no validated definition this anatomic variation. We hypothesized that pelves could be quantitatively grouped by measurements. Methods: One hundred four computed tomography (CT) scans virtual outlet views uninjured were analyzed for presence five qualitative characteristics dysplasia. CT...
Although randomized controlled designs are considered the so-called gold standard in medical trials and sit atop hierarchy of evidence evidence-based medicine, there situations which they impractical or unethical to undertake, especially surgical trials. Then, observational studies often provide best source information. In this paper, we use examples from literature explain importance furthering boundaries orthopaedic surgery knowledge musculoskeletal disorders.
It is unclear whether there a limit to the amount of distal bone required support fixation supracondylar periprosthetic femoral fractures. This retrospective multicentre study evaluated lateral locked plating fractures and compared results according extension fracture with proximal border prosthetic component. Between 1999 2008, 89 patients underwent fracture, whom 61 mean age 72 years (42 96) comprising 53 women, were available after minimum follow-up six months or until healing. Patients...
Background: There is increasing evidence associating "atypical" femoral fractures with prolonged exposure to bisphosphonate therapy. The cause of these unknown and likely multifactorial. This study evaluated the hypothesis that patients primary osteoporosis who sustain atypical fracture(s) while on chronic therapy have a more varus proximal geometry than use bisphosphonates for but do not fracture. Methods: neck-shaft angle was measured radiographs 111 shaft thirty-three asymptomatic...
The Lancet Commission on Global Surgery established the Three Delays framework, categorising delays in accessing timely surgical care into seeking (First Delay), reaching (Second and receiving (Third Delay). Globally, knowledge gaps regarding for fracture care, lack of large prospective studies informed rationale our international observational study. We investigated hospital admission as a surrogate explored factors associated with delayed admission.
Fractures of the hip have devastating effects on function and quality life. Intramedullary nails (IMN) are dominant implant choice for treatment trochanteric fractures hip. Higher costs IMNs inconclusive benefit in comparison with sliding screws (SHSs) convey need definitive evidence.To compare 1-year outcomes patients treated IMN vs an SHS.This randomized clinical trial was conducted at 25 international sites across 12 countries. Participants included ambulatory aged 18 years older...
Alternative bearing surfaces offer the potential to reduce wear and improve implant longevity following total hip arthroplasty. However, these technologies are associated with higher costs, for unintended consequences, uncertain benefits in terms of long-term survival implants. The purpose this study was evaluate cost-effectiveness use alternative bearings arthroplasty.A decision-analysis model constructed estimate patients undergoing Model inputs, including clinical outcome probabilities,...
Similar outcomes have been reported for obese and nonobese patients after primary total hip arthroplasty (THA), indicating obesity is not a contraindication to arthroplasty. However, may develop implant failure require revision THA. We compared the of THA in matched cohort patients. Patients were stratified into two groups according BMI (body mass index, kg/m2): Group 1 included 31 (BMI > 35), 2 62 < 30) on age, gender, type procedure. Obese had increased operating room time, higher rate...
Background: Lower mortality and improved physical function following major polytrauma have been associated with treatment at level-I trauma centers compared that hospitals without a center (nontrauma centers). This study investigated the impact of trauma-center care on outcomes after pelvic acetabular injuries. Methods: Mortality quality-of-life-related scores were among patients treated in eighteen fifty-one nontrauma fourteen U.S. states. Complete data obtained 829 adult (eighteen to...
There are few recent data examining the epidemiology of severe upper-extremity trauma in non-military patients. We used National Trauma Data Bank (NTDB) to investigate and descriptive characteristics amputations U.S. centers.We queried 2009 2012 NTDB research datasets for patients undergoing major amputation extracted patient population, injury distribution, treating facilities. In addition, multivariable regression models were fit identify correlates reoperation, in-hospital complications,...
