Background and Purpose: Acetabular fractures are often combined with associated injuries to the hip joint. Some of these associated injuries seem to be responsible for poor long-term results and these injuries seem to affect the outcome independent of the quality of the acetabular reduction. The aim of our study was to analyze the outcome of both column acetabular fractures and the influence of osseous cofactors such as initial fracture displacement, hip dislocation, femoral head lesions and injuries of the acetabular joint surface.Methods: A retrospective cohort study in patients with both column acetabular fractures treated over a 30 year period was performed. Patients with a follow-up of more than two years were invited for a clinical and radiological examination. Displacement was analyzed on initial and postoperative radiographs. Contusion and impaction of the femoral head was grouped. Injuries of the acetabular joint surface consisting of impaction, contusion and comminution were recorded. The Merle d'Aubigné Score was documented and radiographs were analysed for arthritis (Helfet classification), femoral head avascular necrosis (Ficat/Arlet classification) and heterotopic ossifications (Brooker classification).Results: 115 patients were included in the follow up examination. Anatomic reduction (malreduction ≤ 1mm) was associated with a significantly better clinical outcome than nonanatomical reduction (p = 0.001). Initial displacement of more than 10mm (p = 0.031) and initial intraarticular fragments (p = 0.041) were associated with worse outcome. Other associated injuries, such as the presence of a femoral head dislocation, femoral head injuries and injuries to the acetabular joint surface showed no significant difference in outcome individually, but in fractures with more than two associated local injuries the risk for joint degeneration was significant higher (p < 0.001) than in cases with less than two of them.In the subgroup of anatomically reconstructed fractures no significant influence of the analyzed cofactors could be observed.Conclusion: Anatomical reduction appears to be an important parameter for a good clinical outcome in patients with both column acetabular fractures. Additional fracture characteristics such as the initial displacement and intraarticular fragments seem to influence the results. Patients should also be advised that both column acetabular fractures with more than two additional associated factors have a significantly higher risk of joint degeneration. © 2013 Lichte et al.; licensee BioMed Central Ltd.

PURPOSE OF REVIEW: There is still an ongoing debate whether damage control orthopedics (DCO) or other treatment strategies should be favored in the treatment of multiply injured patients. This review gives an overview of the current literature concerning this important question in the treatment of severely injured patients. RECENT FINDINGS: Several studies could show that DCO can reduce the inflammatory burden due to surgery (second hit). The only randomized study showed a benefit for borderline patients treated by DCO in comparison to early total care. Other studies showed advantages for early care treatment in similar patients. SUMMARY: In severely injured patients, DCO should be considered. On the other hand, there is still a lack of randomized studies for a more precise characterization of the patients who benefit from DCO treatment. Copyright © 2012 Lippincott Williams & Wilkins.

Purpose: To review technical and patency results with expanded polytetrafluoroethylene (ePTFE)-covered stents for treatment of venous rupture encountered during percutaneous hemodialysis intervention. Materials and Methods: The Fluency covered stent is a tracheobronchial device that was used in an off-label manner to treat percutaneous transluminal angioplasty (PTA)-induced rupture in hemodialysis circuits. Data were retrospectively reviewed for all patients treated with the stent in 2004-2005 at two medical centers for PTA-related rupture. Results: From a database of 106 procedures, 21 patients (21 procedures) were treated with the ePTFE-covered stent for PTA-related extravasation. Nine patients had arteriovenous (AV) grafts and 12 had AV fistulas. Five extravasations followed angioplasty as part of an AV graft declotting procedure. Location of extravasation was the outflow or cannulation venous segment (n = 11), cephalic arch (n = 3), AV graft venous anastomosis (n = 6), and intragraft (n = 1). All procedures were technically successful at halting extravasation and preserving vascular access. There were no known complications, and all patients underwent a successful first dialysis session. Twenty of the 21 circuits remained patent beyond the first week after intervention. The 180-day primary circuit patency rate was 20% and the 180-day cumulative circuit patency rate was 65%. Conclusions: In 21 patients, the ePTFE-covered stent successfully treated PTA-induced rupture with no need for acute secondary procedures such as thrombolysis or surgery. There was no instance of pseudoaneurysm formation or delayed bleeding. The ePTFE-covered stent offers advantages compared to prolonged PTA or bare stents when attempting to preserve hemodialysis access after PTA-induced rupture. © 2010 SIR. Source

The purpose of this study was to determine national practice for obtaining consent in academic adult intensive care units (ICUs) for routine bedside procedures and to define universal consent rates by patient demographics within our own institutionĝ™s ICUs. Methods: A 10-question survey was sent to the program directors for all U.S. surgical and pulmonary critical care directors regarding consent practices. Further, the adoption of a universal consent protocol in an academic county hospital was studied. Results: Cross-sectional study: Thirty-seven percent of program directors completed the survey. Consent rates varied from 35% to 97% by procedure, with only 14% using a universal consent document. Providers in Medical ICUs obtained consent more often than in Surgical ICUs for both central line and pulmonary artery catheter placement (82.8% and 93.1% vs. 52.6% and 52.6%, respectively). Prospective cohort study: At our institution, 90% of 363 patients or their proxies signed universal consent for procedures, 4.4% consent with exemptions, while 5.2% refused. Insured patients were 2.7 times more likely to sign full universal consent for bedside ICU procedures than uninsured patients. Conclusion: There was a national variation in ICU consent practices with an interest in a wider usage of universal consent protocols. The latter was adopted differentially based on patient demographics. Universal consent was widely accepted at our institution. Source

Background: Stabilization after a pelvic fracture can be accomplished with an anterior external fixator. These devices are uncomfortable for patients and are at risk for infection and loosening, especially in obese patients. As an alternative, we recently developed an anterior subcutaneous pelvic internal fixation technique (ASPIF). Questions/purposes: We asked if the ASPIF (1) allows for definitive anterior pelvic stabilization of unstable pelvic injuries; (2) is well tolerated by patients for mobility and comfort; and (3) has an acceptable complication rate. Methods: We retrospectively reviewed 91 patients who incurred an unstable pelvic injury treated with an anterior internal fixator and posterior fixation at four Level I trauma centers. We assessed (1) healing by callous formation on radiographs and the ability to weightbear comfortably; (2) patient function by their ability to sit, stand, lie on their sides, and how well they tolerated the implants; and (3) complications during the observation period. The minimum followup was 6 months (mean, 15 months; range, 6-40 months). Results: All 91 patients were able to sit, stand, and lie on their sides. Injuries healed without loss of reduction in 89 of 91 patients. Complications included six early revisions resulting from technical error and three infections. Irritation of the lateral femoral cutaneous nerve was reported in 27 of 91 patients and resolved in all but one. Heterotopic ossification around the implants, which was asymptomatic in all cases, occurred in 32 of 91 patients. Conclusions: The anterior internal fixator provided high rates of union for the anterior injury in unstable pelvic fractures. Patients were able to sit, stand and ambulate without difficulty. Infections and aseptic loosening were reduced but heterotopic ossification and irritation of the LFCN are common. © 2011 The Association of Bone and Joint Surgeons®. Source
