Operative Versus Nonoperative Treatment of Pediatric and Adolescent Clavicular Fractures: A Systematic Review and Critical Analysis.

BACKGROUND: The optimal treatment of displaced middle-third clavicular fractures in pediatric and adolescent patients remains controversial. Furthermore, risk factors for the failure of nonoperative treatment have not been clearly defined. Therefore, we designed a systematic review and critical analysis to assess appropriate Grades of Recommendation for evidence-based treatment of middle-third clavicular fractures in the pediatric and adolescent populations. METHODS: We performed a systematic review following a search of the PubMed, Embase, and Cochrane databases that was conducted in May 2017. The search terms were clavicle, clavic*, and fracture. Our specific PubMed search was ("clavicle"[MeSH] OR clavic*) AND ("fracture"[MeSH] OR fracture*). The results were filtered for English language and subjects ≤18 years of age. There was no chronological limit on the results. The results were then assessed for relevance via a stepwise approach by first screening titles, then abstracts, and, finally, full text. The levels of evidence were determined for studies that met the inclusion criteria. The findings were summarized, and Grades of Recommendation were assigned by consensus. RESULTS: Our search returned 3,615 studies. Of these, 215 were potentially relevant. Studies that did not meet our inclusion criteria were removed by consensus. One hundred and nineteen full-text articles were then assessed. Of these, 19 met the inclusion criteria. Overall, patients with both operative and nonoperative treatment of displaced middle-third clavicular fractures have good functional outcomes, with Grade-B supporting evidence. There is Grade-B evidence that operative treatment results in a high complication rate. Both plating and nailing have a high likelihood of requiring implant removal, with Grade-B evidence. There is conflicting evidence regarding the effect of both nonoperative and operative treatment on patient cosmesis following displaced fractures. There is Grade-B evidence that nonunions of pediatric clavicular fractures are exceptionally rare, regardless of treatment strategy. Nonoperatively treated displaced fractures have conflicting evidence regarding any adverse effect displacement may have on functional status. CONCLUSIONS: Existing literature does not clearly delineate appropriate indications for nonoperative care or relative indications for operative intervention. Further studies are needed to guide treatment and promote better informed consent. LEVEL OF EVIDENCE: Therapeutic Level IV.

Operative Versus Nonoperative Management of Civilian Gunshot Wounds to the Spinal Cord: Novel Use of the Functional Independence Measure for Validated Outcomes.

BACKGROUND: Surgery for patients with gunshot wound spinal cord injury (GSCI) remains controversial. Few recent studies provide standardized follow-up and detailed functional outcomes. To our knowledge, the research we present in this study is unique in that we are the first to incorporate Functional Independence Measure (FIM) scores as an outcomes measure for neurologic recovery in patients with GSCI. METHODS: Patients with GSCI were divided into surgical and nonsurgical groups. Neurologic function was measured according to the American Spinal Injury Association impairment scale and defined as either complete or incomplete injury. Outcomes were then analyzed separately for complete and incomplete GSCI groups during hospitalization and rehabilitation. RESULTS: Baseline admissions characteristics were similar between surgical and nonsurgical groups except for a greater median injury severity score in the nonsurgical group (34 vs. 27; P = 0.02). For complete GSCI, total length of stay (LOS) was significantly longer in the surgical group (52 vs. 42 days; P = 0.04), and no difference was observed in overall FIM scores (58 vs. 54; P = 0.7). For incomplete GSCI, rehabilitation LOS was longer (35 vs. 21; P = 0.02) and a trend towards longer total LOS was observed in the surgical group (40 vs. 32; P = 0.07). No difference was observed in overall FIM scores (61 vs. 62; P = 0.9). CONCLUSIONS: Surgery for patients with GSCI is associated with increased LOS and is not associated with improved FIM scores for patients with either complete or incomplete spinal cord injuries.

Surgical management of aortic valve disease in the elderly: A retrospective comparative study of valve choice using propensity score analysis.

BACKGROUND AND AIM OF THE STUDY: Aortic valve dysfunction is the most common form of valvular heart disease. As the population continues to age, a greater number of patients will become candidates for aortic valve replacement (AVR); hence, prosthetic valve choice becomes of paramount importance. METHODS: A retrospective analysis was conducted on 801 patients aged > or =65 years who underwent isolated AVR or AVR + coronary artery bypass grafting (CABG) between January 1989 and June 2003 with a Carpentier Edwards Perimount (CEP) pericardial bioprosthesis (n = 398) or a St. Jude Medical (SJM) mechanical valve (n = 403). The mean age of CEP patients was 74.5 years (range: 65-89 years), and of SJM patients 73.9 years (range: 65-90 years). The follow up was 96.2% and 96.5% complete for CEP and SJM patients, respectively. Propensity scoring was used to establish homogeneity of the groups and reduce bias. RESULTS: The operative mortality was 4.0% (n = 16) among CEP patients and 6.5% (n = 26) among SJM patients. Predictors of hospital mortality included: peripheral vascular disease (p = 0.018), surgical urgency (p = 0.010), preoperative intra-aortic balloon pump (IABP) (p = 0.010), intraoperative perfusion time (p = 0.046) and intraoperative IABP (p = 0.001). Postoperative morbidities were similar for the two groups. The mean follow up was 72.4 and 59.2 months for CEP and SJM patients, respectively. The five-year actuarial survival was 70.9 +/- 2.3% for CEP and 71.8 +/- 2.4% for SJM patients; at 10 years the actuarial survival was 32.6 +/- 3.3% and 38.2 +/- 3.8%, respectively. Freedom from reoperation for AVR, stroke and non-fatal myocardial infarction was 98.8% (159/161), 99.4% (160/161) and 99.4% (160/161), respectively, in CEP patients, and 100.0% (220/220), 97.7% (215/220) and 97.7% (215/220), respectively, in SJM patients (p = NS). Predictors of late death (>30 days) included chronic obstructive pulmonary disease (p = 0.001) and mechanical valve replacement (p = 0.001). CONCLUSION: In comparable elderly patients, the outcomes of CEP and SJM valves after AVR showed no significant differences in hospital morbidity, mortality, mid-term survival or late cardiac events. However, the cumulative risk of lifelong anticoagulation with a mechanical valve is a serious consideration that must be factored into the selection algorithm.

Is the St. Jude Medical mechanical valve an appropriate choice for elderly patients?: A long-term retrospective study measuring quality of life.

BACKGROUND AND AIM OF THE STUDY: The selection of a suitable valve substitute in patients requiring valvular heart surgery is an important element in the preoperative decision-making process between cardiologist, surgeon, and patient. Controversy persists regarding the use of mechanical valves in the elderly. With the population living longer, reoperative risk becomes of paramount importance. Quality of life (QOL) considerations are often as important to the patient as longevity. The influence of mechanical valve replacement on QOL in elderly patients has not been well documented. METHODS: Between June 1981 and December 1999, a total of 1,125 consecutive patients aged > or = 65 years (582 men, 543 women; mean age 71.4 +/- 4.9 years) underwent valve replacement with at least one St. Jude Medical (SJM) mechanical valve. Preoperatively, 138 patients (12.3%) were in NYHA class II, 775 (68.9%) in class III, and 212 (18.8%) in class IV. In 535 patients (47.6%), coronary artery disease required surgical intervention. Survivors were administered the Short Form (SF)-36 QOL Survey at follow up, which was 96.1% complete. RESULTS: Hospital mortality was 7.6% (85/1,125). Mean follow up was 5.9 years (range: 9 months to 18.4 years). Mean (+/- SEM) actuarial survival was 70.6 +/- 1.4% at five years, and 40.6 +/- 2.0% at 10 years. Male patients scored significantly higher on the SF-36 than controls in physical (p = 0.012) and mental health (p = 0.004). Comparing female patients with controls revealed no significant difference in physical health; however, they scored higher in mental health than controls (p = 0.001). CONCLUSION: The study results clearly demonstrate that heart surgery in the elderly with the SJM mechanical valve can be accomplished with acceptable hospital mortality, morbidity, and excellent long-term results. Moreover, long-term QOL in elderly patients with a SJM valve can be expected to meet or exceed that of age- and gender-matched controls.

Midterm outcomes using the physio ring in mitral valve reconstruction: experience in 492 patients.

BACKGROUND: Mitral valve reconstruction using standardized Carpentier techniques is the treatment of choice for most patients with regurgitant lesions. Demonstrated predictability and stability make it an attractive alternative to valve replacement. The Physio Ring's inherent flexibility provides a viable alternative in the application of remodeling techniques and appears to be physiologically superior to traditional approaches. METHODS: Between April 1994 and October 2000, 492 consecutive patients underwent mitral valve reconstruction using standardized Carpentier techniques with the Carpentier-Edwards Physio Ring (Edwards Lifesciences LLC, Irvine, CA). There were 267 men (54.3%) and 225 women (45.7%). Mean age was 64.2 years (range, 18 to 86). Almost one-half (44.3%) were 70 years of age or over. The mitral valve etiology was congenital in 7 patients (1.4%), myxomatous in 351 patients (71.3%), ischemic in 88 (17.9%), rheumatic in 26 (5.3%), endocarditis in 9 (1.8%), calcific in 8 (1.6%), and other abnormalities in 3 (0.6%). RESULTS: Isolated mitral valve reconstruction was performed in 282 patients (57.3%), with coronary artery bypass grafting (CABG) in 182 (37.0%), with valve replacement in 11 (2.2%), and with CABG and valve replacement in 17 (3.5%). All patients (100.0%) had ring annuloplasty, 263 (53.5%) leaflet resection, 140 (28.5%) chordal resection, 55 (11.2%) chordal transposition, 48 (9.8%) chordal shortening, and 15 (3.0%) commissurotomy. Overall hospital mortality was 3.5% (17 of 492). Postoperative complications included respiratory insufficiency in 55 patients (11.2%), low cardiac output in 13 (2.6%), stroke in 14 (2.8%), reoperation for bleeding in 13 (2.6%), renal insufficiency in 21 (4.3%), and myocardial infarction in 5 (1.0%), and new onset of atrial fibrillation in 74 patients (15.0%). The cumulative follow-up for the series was 1,522.9 patient years and ranged from 1 to 101.0 months (mean, 38.5 months). There were 11 reconstruction failures (2.3%) requiring ring explant. Actuarial survival was 81.5% +/- 2.1% at 4 years and 67.9% +/- 4.6% at 7 years. Freedom from reoperation at 4 years was 81.5% +/- 2.1% and 67.9% +/- 4.6% at 7 years. CONCLUSIONS: Mitral valve reconstruction with the Physio Ring can be accomplished with low hospital mortality and morbidity even in combined procedures. Moreover, the low incidence of reoperation and late cardiac events suggests that the Physio Ring, with its inherent flexibility, offers a definite advantage in the application of remodeling techniques in mitral valve reconstruction.

Surgical ventricular restoration in the treatment of congestive heart failure due to post-infarction ventricular dilation.

OBJECTIVES: The purpose of this study was to test how surgical ventricular restoration (SVR) affects early and late survival in a registry of 1,198 post-anterior infarction congestive heart failure (CHF) patients treated by the international Reconstructive Endoventricular Surgery returning Torsion Original Radius Elliptical shape to the left ventricle (RESTORE)team. BACKGROUND: Congestive heart failure may be caused by late left ventricular (LV) dilation after anterior infarction. The infarcted segment is often akinetic rather than dyskinetic because early reperfusion prevents transmural necrosis. Previously, only dyskinetic areas were treated by operation. Surgical ventricular restoration reduces LV volume and creates a more elliptical chamber by excluding scar in either akinetic or dyskinetic segments. METHODS: The RESTORE group applied SVR to 1,198 post-infarction patients between 1998 and 2003. Early and late outcomes were examined, and risk factors were identified. RESULTS: Concomitant procedures included coronary artery bypass grafting in 95%, mitral valve repair in 22%, and mitral valve replacement in 1%. Overall 30-day mortality after SVR was 5.3% (8.7% with mitral repair vs. 4.0% without repair; p < 0.001). Perioperative mechanical support was uncommon (<9%). Global systolic function improved postoperatively. Ejection fraction (EF) increased from 29.6 +/- 11.0% preoperatively to 39.5 +/- 12.3% postoperatively (p < 0.001). The left ventricular end-systolic volume index (LVESVI) decreased from 80.4 +/- 51.4 ml/m(2) preoperatively to 56.6 +/- 34.3 ml/m(2) postoperatively (p < 0.001). Overall five-year survival was 68.6 +/- 2.8%. Logistic regression analysis identified EF or=80 ml/m(2), advanced New York Heart Association (NYHA) functional class, and age >or=75 years as risk factors for death. Five-year freedom from hospital readmission for CHF was 78%. Preoperatively, 67% of patients were NYHA functional class III or IV and postoperatively, 85% were class I or II. CONCLUSIONS: Surgical ventricular restoration improves ventricular function and is highly effective therapy in the treatment of ischemic cardiomyopathy with excellent five-year outcome.

Surgical ventricular restoration: the RESTORE Group experience.

Congestive heart failure may be caused by late left ventricular (LV) dilation following anterior infarction. Early reperfusion prevents transmural necrosis, and makes the infarcted segment akinetic rather than dyskinetic. Surgical ventricular restoration (SVR) reduces LV volume and creates a more elliptical chamber by excluding scar in either akinetic or dyskinetic segments. The international RESTORE group applied SVR in a registry of 1198 post-infarction patients between 1998 and 2003. Early and late outcomes were examined and risk factors identified.Concomitant procedures included coronary artery bypass grafting in 95%, mitral valve repair in 22%, and mitral valve replacement in 1%. Overall 30-day mortality after SVR was 5.3% (8.7% with mitral repair vs. 4.0% without repair, p < .001) Perioperative mechanical support was uncommon (< 9%). Global systolic function improved postoperatively, as ejection fraction increased from 29.6 +/- 11.0% to 39.5 +/- 12.3% (p < .001) and left ventricular end systolic volume index decreased from 80.4 +/- 51.4 ml/m(2) to 56.6 +/- 34.3 ml/m(2) (p < .001). Overall 5-year survival was 68.6 +/- 2.8%, Logistic regression analysis identified EF < or = 30%, LVESVI > o = 80 ml/m(2), advanced NYHA functional class, and age > or =75 years as risk factors for death. Five-year freedom from hospital readmission for CHF was 78%. Preoperatively, 67% of patients were class III or IV, and postoperatively 85% were class I or II.SVR improves ventricular function and is highly effective therapy in the treatment of ischemic cardiomyopathy with excellent 5-year outcome.
