Study design

A retrospective single-center and single-surgeon study.

Objectives

This study investigated the clinical and radiological results of skip pedicle screw fixation for adolescent idiopathic scoliosis (AIS).

Summary of background data

At present, the generally used technique for pedicle screw fixation for the surgical correction of AIS entails inserting a pedicle screw into every segment on the corrective side and into every or every other segment on the supportive side. To reduce operation time, blood loss, and cost, we developed skip pedicle screw fixation to achieve correction of AIS using fewer pedicle screws.

Methods

We evaluated 62 consecutive patients who had undergone computer-assisted skip pedicle screw fixation from August 2005 to June 2014. All patients were followed up for at least two years. We investigated the clinical results of skip pedicle screw fixation for AIS.

Results

The mean number of fused vertebrae was 10.3 ± 2.0, the mean surgical time was 242 ± 78 min, and the mean blood loss volume was 1060 ± 688 ml. The mean Cobb angle of main thoracic (MT) curve two years after surgery improved significantly compared with that before surgery (p < 0.01). The mean correction rate of MT curve immediately after surgery was 62.4 ± 12.4% and correction loss of MT curve at two years after surgery was 1.9 ± 5.8°. The SRS-22 subtotal score two years after surgery improved significantly compared to that before surgery (p < 0.01). Although no patients experienced major complications, eight (12.9%) encountered minor complications (two [3.2%] had massive blood loss [>3000 ml], three [4.8%] had a broken screw, one [1.6%] had a set-screw that dropped out, one [1.6%] experienced deep vein thrombosis, one [1.6%] experienced acute renal failure, and one [1.6%] experienced intercostal neuralgia). Revision surgery was not performed.

Conclusions

Subjects with AIS who underwent skip pedicle screw fixation had significantly improved clinical and radiological parameters at two years after surgery, indicating that skip pedicle screw fixation could be used to successfully treat AIS.

Background

Postoperative anemia is frequent after revision of total knee arthroplasty (TKA) with reported transfusion rates up to 83%. Despite increased efforts of reducing blood loss and enhancing fast recovery within the fast-track setup, a considerable transfusion rate is still evident. The aim of this study was therefore to evaluate the effect of a bipolar sealer on blood loss and transfusion in revision TKA.

Methods

In this single-center prospective cohort study with retrospective controls, 51 patients were enrolled in a fast-track setup for revision TKA without the use of a tourniquet. Twenty-five prospectively enrolled patients received treatment with both a bipolar sealer and electrocautery, whereas 26 patients had received treatment with a conventional electrocautery only in the retrospective group.

Results

No significant differences were found neither for calculated blood loss, with 1397 (standard deviation, ± 452) mL in the bipolar sealer group vs 1452 (SD, ± 530) mL in the control group (P = .66), nor for blood transfusion rates of 53% and 46% (P = .89), respectively. Four controls were readmitted within 90 days follow-up.

Conclusion

The use of a bipolar sealer in a TKA revision setting without the use of a tourniquet did not reduce blood loss or blood transfusion rates.  相似文献

Background

Pancreatic fistula (PF) is the major cause for morbidity and mortality following pancreaticoduodenectomy. The primary aim of this study was to compare the occurrence rate of postoperative PF between isolated Roux-en-Y reconstruction (RYR) and conventional reconstruction (CR) after pancreaticoduodenectomy.

Methods

Data of 43 patients who underwent RYC were compared with those of a pair-matched equal number of patients undergoing CR. We also performed a meta-analysis of comparative studies of the two procedures.

Results

The case-matched analysis showed no significant difference in PF occurrence between RYR and CR groups (23.3% versus 25.6%; P = 0.80). Meta-analysis of 1498 patients further confirmed this finding, showing a pooled odds ratio of 1.14 (95% confidence intervals, 0.82–1.58; P = 0.43).

Conclusion

The use of RYR for pancreaticojejunostomy does not seem to decrease the occurrence rate of postoperative PF in patients undergoing pancreaticoduodenectomy.  相似文献

Background

Trunnionosis of the tapered head-stem junction of total hip arthroplasties, either through corrosion or mechanical wear, has been implicated in early implant failure. Retrieval analysis of large numbers of failed implants can help us better understand the factors that influence damage at this interface.

Methods

In this study, we examined 120 retrieved total hip arthroplasties of one bearing design, the 36-mm diameter metal-on-metal, DePuy Pinnacle, that had been paired with 3 different stems. We measured material loss of the bearing and head-trunnion taper surfaces and collected clinical and component data for each case. We then used multiple linear regression analysis to determine which factors influenced the rate of taper material loss.

Results

We found 4 significant variables: (1) longer time to revision (P = .004), (2) the use of a 12/14 taper for the head-trunnion junction (P < .001), (3) decreased bearing surface wear (P = .003), and (4) vertical femoral offset (P = .05). These together explained 29% of the variability in taper material loss.

Conclusion

Our most important finding is the effect of trunnion design. Of the 3 types studied, we found that S-ROM design was the most successful at minimizing trunnionosis.  相似文献

Background

Bone mineral density (BMD) loss around femoral implants, particularly in the proximal femur, is a common outcome after total hip arthroplasty. Previous studies reported the prevention of postsurgical decrease in BMD with the use of osteoporosis drug therapy. This randomized study evaluated the efficacy of alendronate and alfacalcidol for preserving BMD over a long-term follow-up.

Methods

Sixty consecutive patients with hip osteoarthritis who had undergone primary cementless total hip arthroplasty were randomly assigned to an alendronate (n = 20), alfacalcidol (n = 18), or control (n = 22) group. Periprosthetic BMD was measured using dual-energy X-ray absorptiometry at 1 week, 1 year, and the current follow-up (minimum 9 years after surgery). Changes in BMD are reported as mean percentages relative to the values at 1 week (baseline reference).

Results

All groups showed a significant decrease in the BMD of the calcar at the current follow-up compared to the values at both 1 week and 1 year postoperatively (P < .001). The BMD values were significantly higher in the alendronate group than in the alfacalcidol and control groups (P < .05). The BMD values at the current follow-up were 76% ± 30% (alendronate group), 64% ± 22% (alfacalcidol group), and 59% ± 22% (control group) of the baseline values.

Conclusion

Our findings demonstrate the efficacy of early administration of alendronate for the prevention of bone loss in the calcar region.  相似文献

Objective

The neutrophil-to-lymphocyte ratio (NLR) has been used as a surrogate marker of systemic inflammation. We sought to investigate the association between NLR and wound healing in diabetic wounds.

Methods

The outcomes of 120 diabetic foot ulcers in 101 patients referred from August 2011 to December 2014 were examined retrospectively. Demographic, patient-specific, and wound-specific variables as well as NLR at baseline visit were assessed. Outcomes were classified as ulcer healing, minor amputation, major amputation, and chronic ulcer.

Results

The subjects' mean age was 59.4 ± 13.0 years, and 67 (66%) were male. Final outcome was complete healing in 24 ulcers (20%), minor amputation in 58 (48%) and major amputation in 16 (13%), and 22 chronic ulcers (18%) at the last follow-up (median follow-up time, 6.8 months). In multivariate analysis, higher NLR (odds ratio, 13.61; P = .01) was associated with higher odds of nonhealing.

Conclusions

NLR can predict odds of complete healing in diabetic foot ulcers independent of wound infection and other factors.  相似文献

Objective

Most patients with atrial fibrillation (AF) undergoing cardiac surgery do not receive concomitant ablation. This study reviewed outcomes of patients with AF undergoing Cox-maze IV (CMIV) procedure with radiofrequency and cryoablation and coronary artery bypass grafting (CABG) at our institution.

Methods

Between the introduction of radiofrequency ablation in 2002 and 2015, 135 patients underwent left- or biatrial CMIV with CABG. Patients undergoing other cardiac procedures, except mitral valve repair, or who had emergent, reoperative, or off-pump procedures were excluded. Eighty-three patients remained in the study group after exclusion criteria were applied. Freedom from atrial tachyarrhythmias (ATAs) was ascertained using electrocardiogram, Holter monitor, or pacemaker interrogation at 1 to 5 years postoperatively.

Results

Operative mortality was 3%. Freedom from ATAs at 1 year in the CMIV group was 98%, with 88% off antiarrhythmia drugs. Freedom from ATAs and antiarrhythmia drugs was 70% at 5 years.

Conclusions

The addition of CMIV to CABG resulted in excellent freedom from ATAs at 1 to 5 years. These patients are at increased risk for nonfatal complications compared with others undergoing concomitant surgical ablation.  相似文献

Introduction

Triple-negative breast cancers (TNBC) are associated with a poor prognosis owing to an aggressive phenotype. We aimed to carry out a prospective study comparing management strategies and response to therapy in TNBC and non-TNBC patients.

Methods

Data were obtained from a prospectively maintained database of patients treated for breast cancer.

Results

A total of 142 TNBC and 142 age-, stage- and NPI-matched non-TNBC patients were treated. The difference in overall survival between the 2 groups was statistically significant (77% of TNBC patients alive at a mean follow-up of 32 months, versus 92% of non-TNBC patients at a mean follow-up of 38 months, P = 0.0 Log rank test). This survival difference was found to be independent of NPI (P = 0.0 Log rank test). Locoregional recurrence rates were similar between TNBC patients who were treated with wide local excision versus mastectomy (P = 0.449 Log rank test). A significant difference in survival was noted between TNBC patients who responded differentially to neoadjuvant chemotherapy (P = 0.035 Log rank test).

Conclusion

Patients with TNBC have adverse outcomes despite aggressive treatment. The development of effective targeted therapies is essential for this breast cancer subtype.  相似文献

Rationale

Pneumonia remains the most common major infection after cardiac surgery despite numerous preventive measures.

Objectives

To prospectively examine the timing, pathogens, and risk factors, including modifiable management practices, for postoperative pneumonia and estimate its impact on clinical outcomes.

Methods

A total of 5158 adult cardiac surgery patients were enrolled prospectively in a cohort study across 10 centers. All infections were adjudicated by an independent committee. Competing risk models were used to assess the association of patient characteristics and management practices with pneumonia within 65 days of surgery. Mortality was assessed by Cox proportional hazards model and length of stay by a multistate model.

Measurements and Main Results

The cumulative incidence of pneumonia was 2.4%, 33% of which occurred after discharge. Older age, lower hemoglobin level, chronic obstructive pulmonary disease, steroid use, operative time, and left ventricular assist device/heart transplant were risk factors. Ventilation time (24-48 vs ≤24 hours; hazard ratio [HR], 2.83; 95% confidence interval [95% CI], 1.72-4.66; >48 hours HR, 4.67; 95% CI, 2.70-8.08), nasogastric tubes (HR, 1.80; 95% CI, 1.10-2.94), and each unit of blood cells transfused (HR, 1.16; 95% CI, 1.08-1.26) increased the risk of pneumonia. Prophylactic use of second-generation cephalosporins (HR, 0.66; 95% CI, 0.45-0.97) and platelet transfusions (HR, 0.49, 95% CI, 0.30-0.79) were protective. Pneumonia was associated with a marked increase in mortality (HR, 8.89; 95% CI, 5.02-15.75) and longer length of stay of 13.55 ± 1.95 days (bootstrap 95% CI, 10.31-16.58).

Conclusions

Pneumonia continues to impose a major impact on the health of patients after cardiac surgery. After we adjusted for baseline risk, several specific management practices were associated with pneumonia, which offer targets for quality improvement and further research.  相似文献

Introduction

Between January 2013 and September 2015, 135 consecutive renal transplant patients were screened prospectively with ultrasound for renal cell carcinoma (RCC).

Results

Eighteen ultrasound abnormalities were identified with 4 solid lesions detected. Fifty-six other patients were screened retrospectively by referring nephrology groups, with 6 additional malignancies found.

Conclusion

As a result of our data, we recommend and have instituted annual ultrasound screening of native kidneys in all renal transplant patients.  相似文献

Background

This study investigated the prevalence of osteoporosis and the risk factors for its progression in kidney transplant recipients (KTRs).

Methods

Dual energy X-ray absorptiometry was used to prospectively measure changes in bone mineral density (BMD) before kidney transplantation (KT) and 1 year after transplantation in 207 individuals. We also analyzed the risk factors of osteoporosis progression during this period.

Results

Prior to KT, the mean BMD score (T-score of the femur neck area) was ?2.1 ± 1.2, and the prevalence of osteoporosis was 41.5% (86/207). At 1 year post-transplantation, the mean BMD score significantly decreased to ?2.3 ± 1.1 (P < .001), and the prevalence of osteoporosis increased to 47.3% (98/207; P = .277). The BMD score worsened over the study period in 69.1% (143/207) of patients, improved in 24.1% (50/207), and showed no change in 6.8% (14/207). Minimal intact parathyroid hormone (iPTH) improvement after KT was found to be an independent risk factor of osteoporosis progression.

Conclusions

This study demonstrates progressive loss of BMD after KT and sustained secondary hyperparathyroidism might influence the progression of osteoporosis.  相似文献

Background

It is increasingly apparent that the effect of obesity in arthroplasty is joint-specific. This study evaluates the effects of morbid obesity on primary total knee arthroplasty by comparing short-term outcomes between a morbidly obese (body mass index ≥40 kg/m2) and a normal weight (body mass index 18.5-<25 kg/m2) cohort at our institution between January 2003 and December 2010.

Methods

One hundred seventeen morbidly obese patients were compared with 94 normal weight patients. Operative time, length of stay, complications, 30-day readmission, and readmission length were compared.

Results

Morbid obesity conveyed no significant increase in 30-day readmission. Operative time was increased at 100 minutes in the morbidly obese group, compared with 90.5 minutes (P = .026).

Conclusion

Morbid obesity conveyed no increased risk of length of stay or readmission in this cohort.  相似文献

Background

The optimal administration route of tranexamic acid (TXA) in total knee arthroplasty (TKA), and the effect of TXA on hidden blood loss and total blood loss are undetermined. The purpose of this study was to compare the effectiveness of intravenous versus intra-articular application of tranexamic acid in patients undergoing knee arthroplasty.

Methods

A total of 150 patients undergoing primary unilateral total knee arthroplasty were randomly distributed to 3 groups (IV, intra-articular, and control group; each 50 patients) and administrated TXA (1 g IV and 50 mL intra-articular saline, 1 g intra-articularly and 50 mL intra-articular saline, and 0 g and 50 mL intra-articular saline, respectively). The amount of total and hidden blood loss (HBL), drainage, transfusion, changes in hemoglobin levels, and complications were recorded.

Results

Intra-articular use of TXA reduced more total blood loss (P = .011) and reduced more total 48 hours drainage volume than IV use of TXA (P < .001). Two patients received transfusion in IV and control group. No deep venous thrombosis or other severe complications had occurred. The HBL volume had no significant difference among the control, IV, and intra-articular groups (708.6 ± 308.2, 651.7 ± 302.9, and 625.2 ± 252.1 mL, respectively; which was 65.6%, 70.8%, and 81.1% of the total loss).

Conclusion

Intra-articular administration of TXA significantly reduced total blood loss and drainage volume to a greater degree than IV injection in total knee arthroplasty without reduction of HBL.  相似文献

Background

Total knee arthroplasty (TKA) is associated with major blood loss and blood transfusion is often required. This study aimed to evaluate the efficacy of bone wax in reducing blood loss and transfusion rates after TKA.

Methods

A prospective randomized controlled study that included 100 patients undergoing primary unilateral TKA with cement was conducted in a tertiary center between March 2014 and June 2014. The bone wax group received 2.5 g of bone wax, applied onto the uncovered bone around the prostheses and the nail holes before the tourniquet was released, whereas the control group had hemostasis achieved using electrocautery only. Total blood loss was calculated using the hemoglobin balance method.

Results

There were no demographic differences between the 2 groups. The preoperative serum hemoglobin levels were comparable between the 2 groups. The drop in serum hemoglobin levels at 24 h post-TKA was 1.6 ± 0.9 and 2.1 ± 1.1 g/dL in the bone wax and control groups respectively (P = .021), while the drop in serum hemoglobin levels at 72 h post-TKA was 2.7 ± 1.1 and 3.6 ± 1.2 g/dL respectively (P = .013). Total blood loss at 72 h post-TKA was 987.9 and 1183.5 mL for the bone wax and control groups respectively (P = .017). There was no adverse event associated with the use of bone wax at the 3-month follow-up.

Conclusion

The application of bone wax in TKA was safe and effective for reducing total blood loss and maintaining higher hemoglobin levels.  相似文献

Introduction

Fibrogenesis markers, such as alpha-actin (AA), CD163 (macrophages), and E-cadherin, have been studied as chronic kidney allograft injury (CAI) predictors, a major cause of allograft failure.

Objective

Investigate the value of these markers in predicting CAI and initiation of dialysis.

Materials and Methods

Retrospective analysis of 26 kidney allograft biopsies (from 22 patients with CAI) during 2 years, evaluating intensity and percentage of marked cells on glomeruli and tubulointerstitial compartment. At the time of the biopsy, patients were 45.5 ± 15.8 years and 4.2 years after transplant, and they had a mean glomerular filtration rate (GFR) of 25.8 ± 9.9 mL/min. From an average of 8.5 glomeruli per biopsy, there was ≤25% sclerosis in 17 cases, 26% to 50% in 5, and >50% in 4. Interstitial fibrosis or tubular atrophy affected ≤25% of cortical area in 14 cases, 26% to 50% in 8, and >50% in 2. Twelve patients started dialysis 5.8 ± 4.7 years after transplant, with an average GFR 20.9 mL/min at the time of the biopsy.

Results

There was a higher intensity and percentage of CD163-marked cells in the tubulointerstitial compartment in advanced interstitial fibrosis. We found an association between intensity of AA in the tubulointerstitial compartment and initiation of dialysis (P = .003) and a negative correlation between intensity of E-cadherin loss and GFR (r = ?0.56, P = .012).

Conclusions

In our study, intensity of tubulointerstitial AA was shown to be a predictor of initiation of dialysis, and E-cadherin loss intensity was associated to CAI progression. However, prospective and larger studies are needed to evaluate the predictive value of these markers.  相似文献

Aim

The use of circular frame is widely accepted. This is an outcome review on use of circular Ilizarov frame in elderly patients.

Materials & methods

Data from all patients treated with an Ilizarov circular frame between January 2002 and December 2014, who were 65 years of age or over at surgery was collected. Seventy Ilizarov circular frames were applied during this period in our unit at a mean age of 71.2 years. Clinical, radiological and quality of life questionnaire (SF-12) data were gathered. Mortality, complication and revision data were also collected.

Results

Indications of application of Ilizarov frame were fractures (53%), non-unions (19%), deformity correction (7%) and ankle fusions (21%). Mean period of time in the frame was 184.4 ± 84.2 days. Mortality and complication rates were low (5–7%) at a mean follow-up 4.2 years. There was no case of septic arthritis or newly induced deep infection. Physical and Mental components of SF-12 questionnaire returned to normal for that age group. There was no difference between the subgroups (tibia plateau fractures, pilon fractures, ankle fusions, non-unions, deformity correction and miscellaneous trauma) concerning the physical and mental subjective (PCS and MCS SF-12 component) outcomes (p > 0.05).

Conclusions

Ilizarov circular frame as a definitive treatment of many kinds of trauma and orthopaedic conditions can be safely and reliably used in the elderly with good quality of life results.  相似文献

Background

This study biomechanically compares two methods of supraspinatus repair: single row transosseous braided-tape (BT) and suture bridge transosseous equivalent (SBTE) with 2 medial anchors and 2 lateral anchors. The purpose is to test the hypothesis that BT provides superior or equal biomechanical strength compared to SBTE.

Methods

Nine pairs of frozen cadaveric shoulders were selected and both repair techniques were tested on each pair, using a biomechanical testing unit to measure cyclic loading and ultimate load to failure. Moreover, tendon displacement was measured using the percentage of footprint exposed during the cyclic loading phase.

Results

Mean specimen age was 71 years (6 males, 3 females), and mean volumetric bone mineral density was 134 mg/cm3. BT mean ultimate load was 266 ± 81 Newton (N) compared to 398 ± 69 N for SBTE and this difference of 131 N was statistically significant p = 0.025. There was a strong positive correlation between bone mineral density and SBTE construct ultimate load. The difference between the percentage of footprint exposed after cyclic loading of the two repairs was statistically significant with the exception of the 10–80 N load (p < 0.05). The failure mode was suture cutout through the tendon in 88% (7/8) of specimens for both techniques.

Conclusion

SBTE repair with bone anchors provides superior biomechanical strength compared to BT repair in terms of ultimate load and cyclic loading. The tendon-suture junction is the weakness of both methods. These models simulate a complete tear with total loss of contact with rotator interval and infraspinatus. Future studies could focus on a more isolated physiologic supraspinatus tear pattern.

Introduction

Diverticulitis is a common surgical admission that presents with a wide range of symptoms and severity. Overall there has been a shift to conservative management practices, including the consideration of non-antibiotic treatment approaches in select cases.

Methods

A national survey of all consultant surgeons evaluating their practices was performed. Reasons for changes in management, use of radiological imaging, role of non-antibiotic treatment approaches and indications for elective surgical management were evaluated.

Results

Response rate for this survey was 67.7% (n = 67/99). An overwhelming 92.5% stated that computed tomography imaging was routinely used to investigate acute presentations. Interestingly, 22.4% stated they would consider a non-antibiotic treatment approach in uncomplicated diverticulitis. Main reasons for adopting this approach was low inflammatory markers with short duration of symptoms. Co-amoxiclav was the most common antibiotic used for acute diverticulitis, with considerable variability in duration of treatment. Additionally, there was considerable heterogeneity regarding how many recurrences were necessary before surgical management was required.

Conclusion

This review highlights substantial variation in the management of diverticulitis across Ireland. Shifts to non-antibiotic treatment approaches for uncomplicated cases are observed, but less so than in Northern Europe. National guidelines are required to establish uniform treatment protocols including indications for surgical resection.  相似文献

Background

Malseating of ceramic liner appeared as a matter of concern in multibearing metal, although multibearing cup can be coupled with hard liners as well as polyethylene liner. In this metal shell, the inner taper angle should be 10° for the modularity, while standard metal shells for ceramic liner have an inner taper angle of 18°. However, there has been no study in the effect of taper angle to the risk of malseating. We evaluated whether the taper angle of metal shell might affect the malseating of ceramic liner, and dissociation force of ceramic liner from metal shell.

Methods

Three surgeons manually inserted ceramic liners into two designs of metal shell with different tapers angles (10° and 18°). We compared malseating rates of ceramic liners and push-out strengths, which means dissociation force of the ceramic liner from the metal shell, between these two metal shell designs.

Results

The malseating rates in 10° metal shell were higher than those in 18° metal shell (23.3% vs 0%, P < .05). The mean dissociation force (1148.8 ± 46.7 N) in 10° taper cup was higher than that (389.7 ± 108.3 N) in 18° taper cup (P < .01).

Conclusion

Our results suggest that surgeon should be cautious about malseating of ceramic liner when using multi-bearing metal shell with inner taper angle of 10°.

Clinical relevance

When surgeon use multi-bearing metal shell with inner taper angle of 10°, our results suggest that surgeon should be cautious about malseating of ceramic liner.  相似文献

Background

Lumbar decompression surgery is often used to treat neurological symptoms of the lower extremity as a result of lumbar disease. However, this method also leads to the improvement of the accompanying low back pain (LBP). We studied the extent of LBP improvement after lumbar decompression surgery without fusion and the associated preoperative factors.

Methods

Patients (n = 140) with lumbar spinal stenosis (n = 90) or lumbar disc herniation (n = 50) were included. To evaluate the change in LBP, VAS scores and the Oswestry disability index scores were measured before surgery and 2 weeks, 3 months, and 6 months after surgery. The predictors of residual LBP were investigated using logistic regression analyses.

Results

In total, 140 patients were examined. The VAS scores for LBP before surgery and 2 weeks, 3 months, and 6 months after surgery were 4.4 ± 3.0 (mean ± standard deviation), 1.1 ± 1.5, 1.3 ± 1.8, and 1.9 ± 2.2, respectively. LBP significantly improved 2 weeks after surgery (P < 0.001), stabilized between 2 weeks and 3 months after surgery, but was significantly aggravated 3–6 months after surgery (P < 0.001). At 6 months after surgery, 67 (47.9%) patients had a VAS score of >1. The predictors of residual LBP included severe preoperative LBP, degenerative scoliosis and the size of the Cobb angle. The independent predictors, determined by multivariate analysis were degenerative scoliosis and the size of the Cobb angle.

Conclusions

LBP was alleviated at 2 weeks after lumbar decompression surgery for lumbar disc herniation and lumbar spinal stenosis. The predictors of residual LBP after decompression included more severe LBP at baseline, degenerative scoliosis and the size of Cobb angle.
