Background
The number of hemodialysis patients has been progressively increasing in our country. On the other hand, chronic hip arthropathy associated with long-term hemodialysis is a devastating problems affecting patients' quality of life. In our previous study, we proposed a classification system for radiological abnormalities seen in hemodialysis-related hip lesions. The purpose of the study was to propose the surgical strategy for hip disorders caused by long-term hemodialysis.Methods
Patients with a history of hemodialysis for more than 10 years, 191 hip lesions in 165 consecutive patients who visited our institute due to hip symptoms. Various abnormalities were identified in 116 out of 191 hips. A retrospective assessment of the patient record and radiographs was performed for the included subjects examining the natural course of the disease process as well as the results of surgical treatment.Results
Seventy-six hip lesions (69.0%) were conservatively managed at the time of the initial visit. Surgeries were performed for 75 hips (64.7%) during the study period. Among those, surgical treatment was indicated for 40 hips at the time of the initial visit. On the other hand, surgeries were performed for 35 hips during the subsequent follow-up period due to progression of the disease process.Conclusions
Based on the analysis of our surgical experiences by the retrospective chart review, we have established a flowchart of the treatment strategy for chronic hip arthropathy in long-term hemodialysis patients.Study design

Background
Birmingham hip resurfacing (BHR) is the only Food and Drug Administration–approved hip resurfacing system available in the United States and is used as an alternative to conventional total hip arthroplasty in younger patients. The purpose of this study is to report on the midterm outcomes of BHR in patients 55 years and younger, and specifically to examine the risk factors for aseptic failure, all-cause revision, and complications in this patient population.Methods
Four hundred forty-two consecutive patients with 5-year follow-up were retrospectively reviewed. Multivariate analyses were conducted to control for potential confounding factors identified by univariate analyses.Results
Mean follow-up was 71.68 ± 10.24 months. Among the potential risk factors, only female gender and smaller head sizes had a significant univariate relationship with aseptic revision, all-cause revision, and all-cause complications. When both risk factors were included in a multivariable logistic regression model, analyses showed both variables were closely related, with female gender a better predictor of adverse outcomes than head size (ie, small head size can be thought of as a proxy for female gender). The 5-year implant survival is 95.1% females compared to 99.0% in males.Conclusion
Hip resurfacing with BHR has excellent survival rates in young patients with degenerative hip disease. Although this study suggests that females with small templated head sizes may not be suitable candidates for BHR, further studies are needed to better understand the underlying differences in gender. 相似文献3.

Background
A nationwide survey of hip fractures by the Japanese Orthopaedic Association (JOA) from 1998 to 2008 found a drastic increase in incidence. The aims of this study were to elucidate the status of hip fractures from 2009 to 2014 and to survey the causes for delayed surgery.Methods
A tally of all hip fractures that occurred in patients from 2009 to 2014 was conducted in hospitals authorized by the JOA or in clinics with inpatient facilities of the Japanese Clinical Orthopaedic Association (JCOA). A survey of the causes for delay in surgery was conducted at 849 sites and 526 sites participated.Results
A total of 488,759 hip fractures were registered. Increases in incidence from 2009 to 2014 were prominent in the 90–94-year-old age group among women and the 85–89-year-old age group among men. More trochanteric fractures than neck fractures occurred; however, the neck/trochanter ratio increased over time. The mean duration of preoperative hospital stay was 4.8 and 4.5 days, and the mean duration of hospitalization was 40.5 and 36.8 days in 2009 and 2014, respectively. There were significant differences between patients who waited for surgery up to 3 days and those who waited longer than 3 days in date of hospitalization, fracture type, comorbidities, anticoagulant use, surgical procedure, type of physician who administered anesthesia, type of anesthesia, and operating room schedule. Physicians in charge of each patient who waited for surgery for more than 3 days most frequently cited difficulties in securing operating rooms as the cause for delayed surgery.Conclusion
A drastic increase occurred in the number of patients with hip fractures with time in Japan. One problem in the treatment of hip fractures is the long waiting time from hospitalization to surgery resulting from difficulties in securing operating rooms. 相似文献4.

Background
Total hip arthroplasty (THA) has not only been associated with best functional outcomes but also with higher dislocation risk when compared with bipolar hemiarthroplasty (HA). The functionality and activities of daily living (ADL) of patients treated with THA or HA for intracapsular hip fracture (IHF) have been scarcely investigated in comparison with the preoperative status.Methods
Two comparable groups of 60 patients with an IHF who had undergone either THA or bipolar HA were created matching several preoperative characteristics. Matched variables included age, gender, body mass index, surgical delay, American Society of Anesthesiologists class, comorbidity, cognitive status, educational status, prefracture functional status, and radiographic fracture classification. Patients were prospectively followed up for 1 year using telephone interviews.Results
The ambulatory ability (5-item scale) and ADL Index significantly decreased in both the groups in comparison with the prefracture status at the 4-month and 1-year follow-up. The need for walking aids (5-item scale) at 4 months was significantly higher among patients who had undergone HA. Lower scores on the ADL Index were recorded among patients with HA in comparison with those with THA at 4 months and 1 year. No significant differences in ambulatory ability, complication rate, and mortality were detected between the 2 groups although HA and THA were associated with a tendency to a higher prevalence of general and local complications, respectively.Conclusion
THA provides better short-term results in terms of ADLs and allows early discontinuation in the use of walking aids as compared with bipolar HA in elderly cognitively intact patients with IHF. 相似文献5.

Background
Only surgically irrelevant risk factors including sex, African-American ancestry, or exceptional U-stitch anastomosis have been identified to associate with urinary complications after kidney transplantation. The objective was to identify modifiable and nonmodifiable risk factors associated with urinary complications after kidney transplantation.Methods
A single-center study of 3,129 kidney transplants performed over 40 years was conducted to identify independent risk factors using χ2 tests and logistic regression analysis.Results
We identified the quality of the transplant's ureter, cystographic abnormalities in the recipient, and repeat transplantations as independent risk factors for overall urinary complications occurring after kidney transplantation in multivariable analysis. Obesity was associated with an increased risk of urinary fistula, while the presence of a JJ stent was associated with a reduced risk of urinary fistula. The risk of urinary surgical complications for kidney transplantations was reduced when the kidney was recovered from a living related compared to a deceased donor.Conclusions
The risk factors identified in the present study will allow candidates for kidney transplantation to be more informed and will also allow for surgical modifications to limit the occurrence of urinary complications. 相似文献6.

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7.

Background
Periprosthetic fracture following total hip arthroplasty is a significant problem faced by hip surgeons, and its management in elderly patients remains a considerable challenge.Methods
We retrospectively reviewed 28 Vancouver B2 and B3 periprosthetic femoral fractures (PFF) treated with revision of the femoral stems by distally locked, hydroxyapatite-coated uncemented stems (Cannulok). Patients were aged 75 years or older at the time of surgery.Results
The mean follow-up was 44.6 months (range, 24-102). The mean postoperative Oxford hip score was 30.1 (range, 10-46). The rate of fracture union was 95.8%, and the survivorship of the stem was 100% at the end of follow-up.Conclusion
The management of PFF in elderly is associated with increased postoperative morbidity and mortality. The use of a distally locked, hydroxyapatite-coated femoral stem is a valid option for the treatment of PFF to achieve fracture union with a low rate of revision. 相似文献8.

Background
Increased operative time has been associated with increased complications after total joint arthroplasty (TJA). The purpose of the present study was to investigate the effect of operative time on short-term complications after TJA while also identifying patient and operative factors associated with prolonged operative times.Methods
The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2011-2013 to identify all patients who underwent primary total hip or knee arthroplasty. Patients were stratified by operative time, and 30-day morbidity and mortality data compared using univariate and multivariable analyses.Results
We identified 99,444 patients who underwent primary TJA. The overall incidence of complications after TJA was 4.9%. Overall complications were increased in patients with operative times >120 minutes (5.9%) as compared to patients with operative times <60 minutes or 60-120 minutes (4.6% and 4.8%, respectively; P < .001). Wound complications, including surgical site infection, were also increased for procedures lasting >120 minutes. In a multivariable analysis, operative time exceeding 120 minutes remained an independent predictor of any complication and wound complication, with each 30-minute increase in operative time beyond 120 minutes further increasing risk. Patient age ≤65 years, male sex, black race, body mass index ≥30 kg/m2, and an American Society of Anesthesiologists classification of 3 or 4, predicted operative times >120 minutes.Conclusion
We found that operative time >120 minutes was associated with increased short-term morbidity and mortality after primary TJA. Younger age, male sex, black race, obesity, and increased comorbidity were risk factors for operative time exceeding 120 minutes. 相似文献9.
Background
The global rise in infectious disease has led the Center for Disease Control and Prevention and the World Health Organization to release new guidelines for the prevention of surgical site infection.Methods
In this article, we summarize current recommendations based on level of evidence, review unresolved and unaddressed issues, and supplement them with new literature.Results
Although the guidelines discuss major issues in reducing surgical site infection, many questions remain unanswered.Conclusion
These guidelines will hopefully help in setting a standard of care based on best evidence available and focus investigators on areas where evidence is lacking. 相似文献10.

Background
The Japanese Society for Spine Surgery and Related Research (JSSR) performed a third study on complications in spinal surgery in 2011. The purpose was to present information about surgery and complications in a large amount of elderly patients aged 65 years with lumbar spinal stenosis (LSS) without coexisting spondylolisthesis, spondylolysis, or scoliosis, and to compare patients aged ≥80 years to those aged 65–79 years.Methods
A recordable optical disc for data storage was sent by JSSR in January 2012 to 1105 surgeons certified by the JSSR in order to collect surgical data. Data were returned by the end of May 2012.Results
Data were accumulated for 8033 patients aged 65 years. The incidence of surgical complications was 10.8%, and did not differ significantly between age groups. The incidence of general complications was 2.7%, and differed significantly between age groups (p < 0.005). The highest incidence of surgical complications was for dural tear (DT) (3.6%), followed by deep wound infection (DWI) (1.4%), neurological complications (1.3%), and epidural hematoma (1.3%). Spinal instrumentation was applied in 30.3%. Incidences of surgical complications in instrumented and noninstrumented surgery were 17.3% and 8.8%. In instrumented surgery, incidences of surgical and general complications were higher in the ≥80 year age group than in the 65–79 year age group. Logistic regression analyses showed patients with microendoscopic surgery at increased risk of DT. Patients with diabetes mellitus and instrumented surgery showed increased risks of DWI.Conclusions
Incidences of surgical complications did not differ significantly between age groups. Attention should be paid to both surgical and general complications, particularly for postoperative mental disease in instrumented surgery for patients≥80 years old. 相似文献11.

Background
Although use of intramedullary hip screws (IMHS) for intertrochanteric (IT) hip fractures has become more common, limited data have suggested difficulties in conversion to hip arthroplasty. The present study investigates whether conversion of failed IT fracture fixation with an intramedullary vs extramedullary device leads to different rates or types of complications or decreased arthroplasty survivorship.Methods
One hundred eleven patients were converted to hip arthroplasty after previous surgical treatment of an IT fracture from 2000 to 2010. Seventy hips had been treated with an extramedullary fixation device (EFD) and 41 with an IMHS.Results
Length of hospital stay and operative times were similar (6 days and 206 minutes for EFD vs 6 days and 208 minutes for IMHS; P > .7). The presence of a Trendelenburg gait at last clinical follow-up was similar between groups (37% in EFD group and 38% in IMHS group). Five-year survivorship free of revision was 95% in the EFD group and 94% in the IMHS group (P = 1.0). The overall complication rate was similar (21% for EFD vs 27% for IMHS; P = .51) between groups. The most common complication was late periprosthetic fracture in the EFD patients (6% vs 0% in IMHS; P = .29) and intraoperative femoral fracture in the IMHS patients (12% vs 1% in EFD; P = .02).Conclusion
The short-term survivorship of conversion hip arthroplasty after surgical treatment of an IT fracture is excellent regardless of original fracture fixation method. If early complications, particularly periprosthetic fractures, can be minimized, the likelihood of a successful outcome is high. The risk of intraoperative femoral fracture was greater during conversion from an IMHS compared to an EFD. 相似文献12.

Background
Bundled payment programs for primary total joint arthroplasty (TJA) have identified reducing nonhome discharge as a major area of cost savings. Health care providers must therefore identify, risk stratify, and appropriately care for home-discharged TJA patients. This study aimed to analyze risk factors and timing of postdischarge complications among home-discharged primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients and risk stratify them to identify those who would benefit from higher level care.Methods
Patients discharged home after elective primary THA/TKA from 2011 to 2014 were identified in the National Surgical Quality Improvement Program database. Bivariate and multivariate analyses were performed using perioperative variables.Results
A total of 50,376 and 71,293 home-discharged THA and TKA patients were included for analysis, of which, 1575 THA (3.1%) and 2490 TKA (3.5%) patients suffered postdischarge severe complications or unplanned readmissions. These patients were older, smokers, obese, and functionally dependent (P < .001 for all). In multivariate analysis, severe adverse event predischarge, age, male gender, functional status, and 10 other variables were all associated with ≥1.22 odds of postdischarge severe adverse event or readmission (P < .05). THA and TKA patients with 2, 3, or ≥4 risk factors had 1.43-5.06 times odds of complications within 14 days post discharge and 1.41-3.68 times odds of complications beyond 14 days compared to those with 0 risk factors (P < .001 for all).Conclusion
Risk factors can be used to predict which home-discharged TJA patients are at greatest risk of postdischarge complications. Given that this is a growing population, we recommend the development of formal risk-stratification protocols for home-discharged TJA patients. 相似文献13.

Background
Total knee arthroplasty (TKA) is an effective treatment option for patients with advanced osteoarthritis and has become one of the most frequently performed orthopedic procedures. With the increasing prevalence of diabetes mellitus (DM), the burden of its sequela and associated surgical complications has also increased. For these reasons, it is important to understand the association between DM and the rates of perioperative adverse events after TKA.Methods
A retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program database. Patients who underwent TKA between 2005 and 2014 were identified and characterized as having insulin-dependent DM (IDDM), non–insulin-dependent DM (NIDDM), or not having DM. Multivariate Poisson regression was used to control for demographic and comorbid factors and to assess the relative risks of multiple adverse events in the initial 30 postoperative days.Results
A total of 114,102 patients who underwent TKA were selected (IDDM = 4881 [4.3%]; NIDDM = 15,367 [13.5%]; and no DM = 93,854 [82.2%]). Patients with NIDDM were found to be at greater risk for 2 of 17 adverse events studied relative to patients without DM. However, patients with IDDM were found to be at greater risk for 12 of 17 adverse events studied relative to patients without DM.Conclusion
In comparison with patients with NIDDM, patients with IDDM are at greater risk for many more perioperative adverse outcomes relative to patients without DM. These findings have important implications for patient selection, preoperative risk stratification, and postoperative expectations. 相似文献14.

Objective
Explore causes and timing of death from the CoreValve US Pivotal High-Risk Trial.Methods
An independent clinical events committee adjudicated causes of death, followed by post hoc hierarchical classification. Baseline characteristics, early outcomes, and causes of death were evaluated for 3 time periods (selected based on threshold of surgical 30-day mortality and on the differences in the continuous hazard between the 2 groups): early (0-30 days), recovery (31-120 days), and late (121-365 days).Results
Differences in the rate of death were evident only during the recovery period (31-120 days), whereas 15 patients undergoing transcatheter aortic valve replacement (TAVR) (4.0%) and 27 surgical aortic valve replacement (SAVR) patients (7.9%) died (P = .025). This mortality difference was largely driven by higher rates of technical failure, surgical complications, and lack of recovery following surgery. From 0 to 30 days, the causes of death were more technical failures in the TAVR group and lack of recovery in the SAVR group. Mortality in the late period (121-365 days) in both arms was most commonly ascribed to other circumstances, comprising death from medical complications from comorbid disease.Conclusions
Mortality at 1 year in the CoreValve US Pivotal High-Risk Trial favored TAVR over SAVR. The major contributor was that more SAVR patients died during the recovery period (31-121 days), likely affected by the overall influence of physical stress associated with surgery. Similar rates of technical failure and complications were observed between the 2 groups. This suggests that early TAVR results can improve with technical refinements and that high-risk surgical patients will benefit from reducing complications. 相似文献15.

Background
Venous thromboembolism causes significant morbidity and mortality in patients after total joint arthroplasty. Although network meta-analyses have demonstrated a benefit of various thromboprophylactic agents, there remains a concern in the surgical community regarding the resulting wound complications. There is currently no systematic review of the surgical site bleeding complications of thromboprophylactic agents. The aim of this study was to systematically review the surgical site bleeding outcomes of venous thromboembolism prophylaxis in this population.Methods
A systematic review and meta-analysis was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials comparing more than one of low-molecular-weight heparin (LMWH), warfarin, rivaroxaban, apixaban, dabigatran, aspirin, or no pharmacologic treatment in patients after total hip or knee arthroplasty were selected for inclusion. Five meta-analyses were performed to compare LMWH with control, warfarin, apixaban, rivaroxaban, and dabigatran.Results
Forty-five randomized controlled trials of 56,730 patients were included. LMWH had a significantly increased relative risk of surgical site bleeding in comparison with control (relative risk, 2.32; 95% confidence interval, 1.40-3.85) and warfarin (1.54; 1.23-1.94). The relative risk of LMWH trended higher than apixaban (1.27; 1.00-1.63) and was similar to rivaroxaban (0.95; 0.74-1.23). Only 1 study reported the risk of surgical site bleeding in LMWH vs dabigatran (5.97; 2.08-17.11).Conclusion
LMWH increased the risk of surgical site bleeding compared with control, warfarin. and dabigatran and trended toward an increased risk compared with apixaban. The risk of surgical site bleeding was similar with LMWH and rivaroxaban. 相似文献16.

Background
Accelerometer-based, portable navigation devices have been introduced as a less invasive and simpler technique to perform navigated surgical implantation of knee prostheses. They have been postulated to have better accuracy than conventional instruments in restoration of alignment in total knee arthroplasty.Methods
A total of 190 patients were enrolled in this prospective, randomized controlled trial and underwent total knee arthroplasty using either the KneeAlign or conventional guides. Multiplanar alignment was evaluated with a CT imaging protocol.Results
A total of 86.5% of portable navigation device and 82.2% of conventional group had a postoperative hip–knee angle within 3° of neutral alignment (P = .54). There was no significant difference between the 2 groups for component coronal and sagittal plane alignment. Portable navigation device did not significantly increase the time to perform the surgery.Conclusion
Portable navigation device demonstrates accurate restoration of alignment; however, there was no statistically significant difference when compared with conventional guides. 相似文献17.

Background
Although venous thromboembolism is one of the leading causes of morbidity after knee arthroplasty, little data exist on the risk of deep venous thrombosis (DVT) after unicompartmental knee arthroplasty (UKA).Methods
We prospectively enrolled 112 patients undergoing UKA to determine the incidence of DVT utilizing aspirin 325 mg twice a day (BID) for 4 weeks postoperatively as DVT prophylaxis. The data were compared with a recent randomized controlled trial of patients undergoing total knee arthroplasty utilizing aspirin and Lovenox in conjunction with pneumatic compression devices.Results
One patient (0.9%) had an asymptomatic DVT, and none developed clinical symptoms of either DVT or pulmonary embolus. The incidence of asymptomatic and symptomatic DVT was 0.9% and 0%, respectively.Conclusion
Our data suggest that 325 mg of aspirin BID for 4 weeks results in a very low risk of DVT for patients undergoing UKA. 相似文献18.

Background
To evaluate the long-term clinical and radiological outcomes of cementless total hip arthroplasty (THA) in high riding hip dislocated patients with previous proximal femoral osteotomy.Methods
Twenty-one consecutive patients with a mean age forty-two years were treated with cementless THA Step-cut subtrochanteric femoral osteotomy was performed in all twenty-eight hips. Metal on polyethylene (MoP) and ceramic on ceramic (CoC) bearings were used in two different consecutive time periods. The mean follow-up time was twelve years. Harris hip score, limb length discrepancy, complications, union status of the osteotomy, survivorship of constructs were the criteria for evaluation.Results
The mean Harris hip score improved from 39.5 to 88.7 points. The mean limb length discrepancy in unilateral cases decreased from 54.5 mm to 12.3 mm. The mean amount of femoral shortening was 37 mm. The mean union time was 3.5 months and there were no delayed union and non-union. There were three cup and two femoral revisions due to osteolysis in patients who had MoP. There was only one femoral revision in patients who had CoC. The Kaplan Meier survivorship with an end point of any revision of the stem and the acetabular component was 94% (95% CI, 75%–98%) and 92% (95% CI, 74%–99%) at ten years respectively.Conclusions
Total hip arthroplasty with subtrochanteric step-cut femoral shortening is a successful technique to improve the hip functions and reconstruct limb length discrepancy in young patients with proximal femoral deformities. 相似文献19.

Background
Impact of gender on 30-day complications has been investigated in other surgical procedures but has not yet been studied in total hip arthroplasty (THA) or total knee arthroplasty (TKA).Methods
Patients who received THA or TKA from 2012 to 2014 were identified in the National Surgical Quality Improvement Program database. Patients were divided into 2 groups based on gender. Bivariate and multivariate analyses were performed to assess associations between gender and patient factors and complications after THA or TKA and to assess whether gender was an independent risk factor.Results
THA patients consisted of 45.1% male and 54.9% female. In a multivariate analysis, female gender was found to be a protective factor for mortality, sepsis, cardiovascular complications, unplanned reintubation, and renal complications and as an independent risk factor for urinary tract infection, blood transfusion, and nonhome discharge after THA. TKA patients consisted of 36.7% male and 62.3% female. Multivariate analysis revealed female gender as a protective factor for sepsis, cardiovascular complications, and renal complications and as an independent risk factor for urinary tract infection, blood transfusion, and nonhome discharge after TKA.Conclusion
There are discrepancies in the THA or TKA complications based on gender, and the multivariate analyses confirmed gender as an independent risk factor for certain complications. Physicians should be mindful of patient's gender for better risk stratification and informed consent. 相似文献20.
