Pediatric all-terrain vehicle (ATV) injuries: An epidemic of cost and grief.

OBJECTIVE: Evaluate cost of care of all-terrain vehicle (ATV) related injuries sustained by riders 16 years and younger in Pennsylvania. METHODS: Population-based retrospective cohort design reviewing costs of care of 78 patients (≤16 years), admitted (01/01/2007-12/31/2009) to our institution for injuries sustained during an ATV accident. RESULTS: Cost of care varied from $322 to $310,435. Mean and median costs for all patients were $25,760 and $8,066, respectively. Average costs increased with increasing age. Patients wearing helmets or driving the ATV had lower mean costs, but these trends were not statistically significant. Crashes with stationary objects not involving rollover or ejection had significantly lower mean costs than other crash types (p = 0.01). Patients involved in rollover accidents were significantly more likely to require an overnight hospital stay (OR = 3.45, p = 0.02). Patients wearing helmets were marginally less likely to require an overnight admission (OR = 0.34, p = 0.07). CONCLUSION: ATV crashes involving unhelmeted riders and rollover accidents result in significant medical costs. Interventions to increase helmet use and measures to improve stability are likely to reduce these costs and shorten hospital stays. LEVEL OF EVIDENCE: Level IV, Economic study.

Reducing mortality in hip fracture patients using a perioperative approach and "Patient- Centered Medical Home" model: a prospective cohort study.

BACKGROUND: Hip fracture patients experience high morbidity and mortality rates in the first post-operative year after discharge. We compared mortality, utilization, costs, pain and function between two prospective cohorts of hip fracture patients, both managed with identical perioperative protocols and one group subsequently managed via a "Patient-Centered Medical Home" (PCMH) primary care management model. METHODS: We analyzed 6 and 12-month outcomes from two matched cohorts of patients who were surgically treated for hip fracture from January 1, 2010 to June 30, 2011 at two hospitals (n = 194). Controls did not receive PCMH and were matched to cases on surgery date, sex, age, and comorbidities. Mortality and healthcare utilization were the primary outcomes studied, with medical costs, quality of life, pain and function at 12 months assessed as secondary outcomes in a subgroup. Survival analysis, regression and Student-t testing were used with p < 0.05 considered significant. RESULTS: At 6 months, PCMH patients had significantly lower mortality than patients receiving standard care (11% vs. 26%, p < 0.01). At 12 months, a difference persisted (23% vs. 30%, p = 0.12) but was no longer statistically significant. Mean quality of life scores were similar (0.73 vs. 0.76, p = 0.49) and Harris Hip score was slightly improved for PCMH (73 vs. 64, p = 0.04). Mean costs per patient per month were lower for PCMH but not significantly different ($69 vs. $141, p = 0.20 for pharmacy costs; $1212 vs. $1452, p = 0.45 for non-pharmacy costs). CONCLUSIONS: Patients receiving aggressive post-discharge care from a PCMH program showed significant benefits in terms of reduced mortality at 6 months, with similar costs and functional outcomes at 12 months. PCMH was not shown to improve all outcomes studied, but these results suggest that ongoing Medical Home management can have some benefit for patients without negatively impacting function or cost.

Hemodynamically unstable pelvic fracture management by advanced trauma life support guidelines results in high mortality.

The purpose of this study was to examine the acute outcomes and mortality rates of an Advanced Trauma Life Support guideline approach for managing hemodynamically unstable pelvic ring injuries. We retrospectively reviewed the acute outcomes of 48 consecutive patients with hemodynamically unstable pelvic fractures. Patients underwent treatment via the advanced trauma life support protocol, with primary angiography based on trauma surgeon preference. Mean patient age was 51.2 years, with a mean injury severity score of 43.2±14.3. Mean systolic blood pressure was 74.8±16.1 mm Hg at presentation. Patients received an average of 7.0±6.6 units of red blood cells and 4.2±2.3 units of fresh frozen plasma in the first 6 hours. Fourteen patients underwent emergent angiography, and 12 patients were treated with embolization. Mean time to angiography was 3 hours and 55 minutes (range, 2-19 hours). Twenty patients died during hospitalization, with an overall mortality rate of 41.7%; 13 (27.1%) of them died within 24 hours. Advanced Trauma Life Support guidelines with angiography are not adequate for the management of hemodynamically unstable pelvic ring injuries and result in unacceptably high mortality rates compared with more specific approaches using transfusion protocols and interventions, such as pelvic packing.

Delayed flap reconstruction with vacuum-assisted closure management of the open IIIB tibial fracture.

OBJECTIVE: Vacuum-assisted closure (VAC) therapy has been shown to be effective at reducing bacterial counts in wounds until definitive bony coverage. However, there is continued debate over timing and type of definitive wound coverage even with VAC therapy application. METHODS: From 2004 to 2009, 32 patients with Gustilo type IIIB open tibia fractures were initially treated with VAC therapy were included. The number of debridements, length of treatment with VAC dressing, definitive wound coverage management, and length of hospital stay, flap-related complications, and time to radiographic fracture healing were recorded. RESULTS: The mean Injury Severity Score was 17.3 ± 2.0. All wounds closed after being treated with the primary VAC closure. The mean interval between the initial injury and definitive intervention was 10.9 days ± 0.3 days. Twenty of 27 patients (74%) underwent rotational muscle flaps; four received free muscle flaps and three only with split-thickness skin grafts for definitive wound coverage. Nine of 32 patients (28%) underwent below knee amputation, five without flap coverage after several VAC sessions and four after definitive flap coverage. The average time to union was 10.0 months ± 2.0 months. Eight patients developed nonunion and 11 patients developed infections. The average follow-up time is 2.4 years ± 0.2 years. Patients were divided into two groups for analysis according to the interval time. The rate of infection was significantly increased in patients who had an interval of more than 7 days from the time of injury to flap coverage. CONCLUSIONS: The VAC therapy may help to reduce the flap size and need for a flap transfer for type IIIB open tibial fractures. However, prolonged periods of VAC usage, greater than 7 days, should be avoided to reduce higher infection and amputation risks.

Treatment of interprosthetic fractures of the femur.

BACKGROUND: The treatment of interprosthetic femoral fractures is challenging because of several factors. Poor bone stock, advanced age, potential prosthetic instability, and limited fracture fixation options both proximally and distally can complicate standard femur fracture treatment procedures. The purpose of this report was to describe our experience treating interprosthetic femoral fractures, providing an emphasis on treatment principles and specific intraoperative management. METHODS: All patients with fractures occurring between ipsilateral hip and knee prostheses between 2004 and 2010 were identified from a comprehensive database and included in this study. Patients had been treated using principles adapted from two isolated periprosthetic fracture classification systems, the Vancouver and Su classifications. The electronic medical record (including inpatient medical records, operative notes, outpatient medical records, and all radiographs) was reviewed for each patient and demographic and treatment-related variables as well as complications and outcomes were recorded. RESULTS: Thirteen consecutive patients with interprosthetic fractures were included. Four fractures occurred around a clearly loose prosthesis, which were subsequently treated with long-stemmed revisions. The remaining 12 fractures were treated with a locked-plate construct. Two of nine patients (22.2%) died before fracture union. Follow-up averaged 28 months ± 4 months, with fracture union achieved at an average of 4.7 months ± 0.3 months. All patients returned to their self-reported preoperative ambulatory status except one who developed a loose hip prosthesis at 3-year follow-up after fracture union. CONCLUSIONS: The principles for treatment of isolated periprosthetic fractures are useful to guide the fixation of interprosthetic fractures. Locked plating is an effective method for the treatment of interprosthetic femoral fractures. Bypassing the adjacent prosthesis by a minimum of two femoral diameters is a necessary technique to prevent a stress riser.

Severe postpartum disruption of the pelvic ring: report of two cases and review of the literature.

Pelvic dislocations are rare during labor, and the treatment is controversial. We report two cases of young women who sustained postpartum disruption of the pelvic ring: one case is an 8.8 cm wide separation of the pubic symphysis with sacroiliac joint disruption underwent surgical stabilization and the second case with 4.0 cm disruption being treated non-operatively. These cases illustrated of importance of accurate diagnosis, careful physical exam, fully informed consent and specific treatment for this condition.
