Osteosynthesis versus endoprosthesis in the treatment of unstable intracapsular hip fractures in the elderly

Forty-three elderly patients with an intracapsular hip fracture were selected for a prospective randomised trial comparing osteosynthesis (DHS) versus primary hemiarthroplasty (HA) with a 3-year follow-up. The duration of the operation and the perioperative blood loss were significantly shorter in DHS, but inadequate reduction and/or fixation led to serious problems in this group. Clinical morbidity was lower after DHS. No difference could be demonstrated in the mortality rates, fracture- or operation-related complications or the need for secondary intervention. Reintervention could be carried out without additional risk in both groups and did not lead to poor end results. Comparable results were obtained with both methods up to 24 months. At the 36-month follow-up, a significantly worse outcome could be demonstrated in the HA group. We conclude that osteosynthesis is justified as the primary treatment of displaced intracapsular hip fractures in elderly patients. Endoprosthetic replacement can be safely used in cases where osteosynthesis has failed.     

Analysis of factors among 30-day and 1-year mortality rates in patients with borderline stable-unstable intertrochanteric hip fracture

ObjectiveThis study aimed to evaluate the possible effects of surgical procedures on mortality and to identify the possible risk factors for mortality in the management of geriatric hip fractures.MethodsA total of 191 patients (105 women and 86 men; mean age 82.26±9.681 [60–108] years) with AO/OTA 31A2.2 intertrochanteric fractures and treated with sliding hip screw, proximal femoral nail, or hemiarthroplasty were included in this retrospective cohort study. The treatment type was decided by the responsible surgeon according to the patients’ pre-injury activity level, bone quality, and features of the fracture. Age, sex, type of fracture, type of surgery performed, American society of anesthesiology (ASA) grade, type of anesthesia, time to surgery, type of physical therapy, length of hospital stay, and number of comorbidities were documented. We evaluated the 30-day and 1-year mortality of patients treated with sliding hip screw (SHS), proximal femoral nail antirotation (PFN-A), or hemiarthroplasty and identified the possible risk factors for mortality.ResultsA total of 49 patients underwent SHS, 58 underwent PFN-A, and 84 underwent hemiarthroplasty. Of these, 2 patients with SHS, 2 with PFN-A, and 11 with hemiarthroplasty died within 30 days after surgery, whereas 7 patients with SHS, 15 with PFN-A, and 23 with hemiarthroplasty died 1 year after surgery. The 30-day and 1-year overall mortality rates were 7.9% and 23.6%, respectively. Both the 30-day and 1-year mortality risks were higher in patients undergoing hemiarthroplasty than in patients undergoing SHS (p=0.068 versus 0.058). The 30-day mortality was higher in patients receiving general anesthesia than in those receiving combined spinal and epidural anesthesia (p=0.009). The 1-year mortality risk was higher in patients with ASA grade 4 than in those with grade 1 and 2 (p=0.045). Advanced age (p=0.022) and male sex (p=0.007) were also found to be the risk factors for 1-year mortality.ConclusionWe demonstrated that higher ASA grade, male sex, general anesthesia, and hemiarthroplasty procedures are associated with higher mortality rates in elderly patients with hip fractures. Thus, we highly recommend orthopedic surgeons to consider all these factors in the management of intertrochanteric hip fractures in the geriatric population.Level of EvidenceLevel IV, Prognostic Study     

Die Schenkelhalsfraktur beim alten Menschen – Bipolare Hemiendoprothese vs. Totalendoprothese

INTRODUCTION: In this study surgical risk and functional outcome of bipolar hemiarthroplasty and total hip replacement in elderly patients with femoral neck fractures were compared. METHODS: In a prospective study 54 patients with femoral neck fractures (median age: 80.5 years) were treated by implanting a total hip replacement (group I). Group II comprised 52 patients with 55 femoral neck fractures (median age: 81 years) who underwent bipolar hemiarthroplsty. Pre- and postoperative mobility and social history, perioperative parameters such as duration of surgery, blood loss, and number of transfused blood units as well as postoperative complications and mortality were compared. Function was ascertained by a scoring system. RESULTS: Duration of surgery, blood loss, and numbers of transfused blood units were significantly lower in group II, and mortality rate was lower. Postoperative mobility and medium-term functional score were comparable, whereas in the longer-term follow-up after 8 years group I had a significantly better functional score. CONCLUSION: In elderly patients with femoral neck fracture and high comorbidity, we recommend the implantation of hemiarthroplasty and in healthy, active patients with longer life expectancy the total hip replacement.     

Early revision after hemiarthroplasty and osteosynthesis of cervical hip fractureShort-term function decreased,mortality unchanged in 102 patients

Background?There is no consensus on whether osteosynthesis or hemiarthroplasty is preferable in the treatment of cervical hip fractures. Osteosynthesis is associated with more reoperations than hemiarthroplasty but there is little information available on the consequences of these reoperations. Patients and methods?We studied the effect on mortality, hospital stay and functional outcome of revision performed within 4 months of primary surgery with hemiarthroplasty or osteosynthesis for cervical hip fracture. 50 (6%) of 792 patients treated with uncemented Austin-Moore hemiarthroplasty and 52 (13%) of 411 patients with osteosynthesis (86 with two hook pins and 325 with three cannulated screws) had had revision surgery. Control groups matched for age, sex, residential status, walking ability at fracture, type of primary operation and fracture type consisted of patients who had not had a reoperation. Results?Reoperation impaired walking ability and was associated with increased use of walking aids at 4 months in the hemiarthroplasty group and the osteosynthesis group as compared to controls, but did not have any statistically significant effect on residential status. In the hemiarthroplasty group, 4-month mortality was 12% among the reoperated patients and 18% among the controls, while mortality at 1 year was 24% in both groups. The corresponding figures in the osteosynthesis group and controls were 6% and 6% at 4 months, respectively, and 17% and 13% at 1 year. Interpretation?To some extent, reoperation impairs early functional outcome after cervical hip fracture treated by either osteosynthesis or hemiarthroplasty, but does not increase mortality to any significant degree.

人工股骨头置换治疗老年不稳定型股骨转子间骨折的临床效果

目的：探讨人工股骨头置换治疗老年不稳定型股骨转子间骨折的方法及临床价值。方法选择2007年10月~2012年10月我院收治不稳定型股骨转子间骨折的老年患者53例,分为人工股骨头置换组23例、动力髋部螺钉方法（DHS对照组）30例,比较两组手术及随访情况。结果人工股骨头置换组老年患者的手术时间、术中出血量、术后下床时间以及术后并发症发生率比对照组明显减少,Harris评分优良率显著增加,差异均具有统计学意义（P＜0.05）。结论人工股骨头置换术能够使老年不稳定型股骨转子间骨折患者住院时间短、出血量少,功能恢复快,具有重要的临床意义,可广泛应用。     

Effect of early surgery in high surgical risk geriatric patients with femoral neck fracture and taking antiplatelet agents

AIM: To investigate the effect of early surgical intervention on the high surgical risk elderly patients who sustained femoral neck fracture (FNF) and taking concomitant antiplatelet agents.METHODS: Between 2010 and 2012, a prospective study was conducted on 49 geriatric patients, who took antiplatelet agents, sustained FNF and underwent surgery within 72 h [early surgery (ES) group], and these were compared with a retrospective consecutive case series of patients with similar characteristics (45 cases) who had delayed surgery (DS group) after 72 h during an earlier 3-year period. Postoperative outcomes were followed for one year and compared.RESULTS: There were non-significant differences in perioperative blood loss, blood transfusion, intensive care unit requirement and postoperative mortality (P > 0.05 all). There were 2 patients (4%) in the DS group who died after surgery (P = 0.23). However, the ES group showed a significantly better postoperative outcome in terms of postoperative complications, length of hospital stay, and functional outcome (P < 0.05 all).CONCLUSION: Early hip surgery in geriatric hip fracture patients with ongoing antiplatelet treatment was not associated with a significant increase of perioperative blood loss and postoperative mortality. Moreover, ES resulted in a better postoperative surgical outcome. In early hip surgery protocol, the antiplatelet agents are discontinued and the patient is operated on within 72 h after admission, which is safe and effective for the medically fit patients.

Bipolar hemiarthroplasty in unstable intertrochanteric fractures in elderly patients. The predictive value of the Charlson Comorbidity Index in 1-year mortality

BackgroundHip fractures have a significant impact on morbidity and mortality in the elderly. Aims: We retrospectively evaluated the predictive role of the Charlson Comorbidity Index (CCI) for 1-year mortality in elderly patients with unstable intertrochanteric hip fractures (ITHF) treated with bipolar hemiarthroplasty. The secondary objective was to identify other relationships, if any, between the variables recorded and mortality.MethodsWe included ≥75-year-old patients with unstable ITHF treated with bipolar hemiarthroplasty. We recorded patient gender, age, Body Mass Index, pre-fracture walking ability (Parker Mobility score, modified Harris Hip Score), America Society of Anesthesiologists (ASA) score, Charlson Comorbidity Index (CCI), time to surgery, time to mobilization, hospital stay, and postoperative complications. Uni- and multivariate logistic regression analysis were performed. Sensitivity and specificity were calculated using a ROC curve.ResultsA total of 135 patients with a mean age of 87.34 ± 5.5 years were included. The overall 1-year mortality rate was 18.5%. The CCI (OR 1.64 CI 95% 1.21–2.23; p 0.00821) and postoperative complications (OR 3.5 CI 95% 1.19–10.23 p 0.0202) were identified as independent predictors of 1-year mortality in the univariate regression and confirmed in the multivariate regression. CCI sensitivity to predict 1-year mortality was 80%.ConclusionCCI has shown acceptable sensitivity in the prediction of 1-year mortality in elderly patients with unstable ITHF treated with bipolar hemiarthroplasty. It is of utmost importance to prevent postoperative complications due to their significant impact on 1-year mortality.     

Effectiveness of anabolic steroids in improving outcomes for post-operative hip fracture patients: A randomized controlled trial

BackgroundPost-operative elderly hip fracture patients require significant rehabilitation. Nandrolone is an anabolic steroid used to promote muscle growth. This study aims to examine the effect of nandrolone in improving rehabilitation and quality of life in elderly female patients with hip fractures undergoing hemiarthroplasty.MethodsThis is a double-blinded prospective randomized-controlled-trial consisting of female patients above the age of 65 with an isolated neck of femur fracture planned for a hip hemiarthroplasty. Participants were randomized into two arms of the study – 50 mg intramuscular nandrolone vs normal saline placebo administered on post-operative day 0, and weeks 2, 6 and 12. The participants were followed up across a 1-year period following the surgery. Clinical outcomes such as time taken to achieve rehabilitation milestones, distance of ambulation and thigh muscle girth, and functional scoring with SF-36 questionnaire were recorded at intervals of 2, 6 and 12 weeks, 6 months and 1 year following the surgery.ResultsThere were a total of 23 subjects with 11 in the steroid group and 12 in the placebo group. There was no significant difference in demographics and injury patterns between both groups. There was no significant difference for time taken to achieve various rehabilitation milestones and distance of ambulation. SF-36 scores on discharge and at 1-year follow-up mark were comparable. There was no difference in the complication rate between both groups.ConclusionIntra-muscular Nandrolone after hip surgery in elderly female patients does not result in short to mid-term improved rehabilitation or functional outcomes. Nandrolone did not result in increased short-term complications after hip surgery.Level of evidenceI.     

Periprosthetic Hip Fractures With a Loose Stem: Open Reduction and Internal Fixation Versus Stem Revision

BackgroundIt is recommended revision for periprosthetic hip fractures (PPHF) with a loose stem. However, several authors have argued that under certain conditions, this fracture could be treated using osteosynthesis. The aim is to compare stem revision versus internal fixation in the treatment of PPHF with a loose stem.MethodsAll patients with PPHF with a loose stem treated by osteosynthesis and stem revision between January 2009 and January 2019 were included. We assessed hospital stay, American Society of Anesthesiologists, Charlson comorbidity index, surgery time, blood transfusion, complications, reoperation rate, first-year mortality, radiological, and functional results.ResultsA total of 57 patients were included (40 osteosyntheses and 17 stem revision), with an average follow-up time of 3.1 years. Their mean age was 78.47 years (R 45-92). In the osteosynthesis group, fewer patients required blood transfusion (32.5% vs. 70.6%), surgical times were shorter (108 minutes vs. 169 minutes), and the cost was lower, both in terms of total cost (€14,239.07 vs. €21,498.45 and operating room cost (€5014.63 vs. €8203.34). No significant differences were found between the groups in terms of complications, reoperation rate, or functional outcomes.ConclusionCompared with stem revision, osteosynthesis requires less surgery time, has a lower need for blood transfusions, and a reduced hospital cost. Stem revision remains the treatment of choice in PPHF with a loose stem, but in V-B2 fractures in elderly patients with low functional demand, high anesthetic risk (American Society of Anesthesiologists ≥3), and many comorbidities (Charlson comorbidity index ≥5) in whom anatomic reconstruction is possible, osteosynthesis can be a viable option.Evidence LevelHistorical cohorts. Level III.     

Blood transfusions and hip fracture mortality - A retrospective cohort study

BackgroundHip fractures are associated with serious morbidity and mortality. Low haemoglobin at presentation has been shown to be associated with increased mortality in hip fracture patients. This comorbid patient group commonly receives packed red cell blood transfusions during their hospital admission, the impact of which is less clear.Aims and objectivesWe aim to assess the rate, appropriateness and impact of blood transfusions on one-year mortality in hip fracture patients. We also aim to assess the impact of patients taking anticoagulant medications at presentation on the rates of blood transfusions in this patient group.MethodsA retrospective cohort study of 324 consecutive hip fracture patients. Data was collected from the national hip fracture database, electronic patient records and PACS.Results75 patients received a blood transfusion. Receiving a blood transfusion increased absolute risk of one-year mortality by 2.466 (p < 0.05). Adjusted for age, sex, comorbidities, residence prior to admission and time from presentation to surgery increased the risk of one-year mortality was 2.790 (p < 0.05).28% of patients who went on to receive a transfusion had a haemoglobin of less than 100 g/L at presentation. 94.6% of transfused patients had a pre-transfusion haemoglobin of less than 90 g/L. There was no increased risk of requiring a blood transfusion if anticoagulant medication was being taken at presentation.ConclusionReceiving a blood transfusion during an admission for hip fracture carried an increased risk of one-year mortality of almost two and a half times. With appropriate preoperative optimisation, taking an anticoagulant medication at presentation did not increase the risk of requiring a transfusion. Most blood transfusions were administered appropriately using thresholds. Just over a quarter of patients who received a transfusion had an admission haemoglobin of less than 100 g/L, showing it as a poor predictor of blood transfusion requirement during admission.     

双极人工股骨头与PFNA在不稳定型股骨粗隆间骨折的疗效评析

目的评价双极人工股骨头置换与股骨近端防旋髓内针（PFNA）内固定治疗高龄骨质疏松性股骨粗隆间骨折的临床疗效,探讨其合理的治疗方法。方法回顾性分析2009年1月~2013年9月期间,在农垦三亚医院采用双极人工股骨头置换（32例）与PFNA内固定治疗（43例）共75例70岁以上的股骨粗隆间骨折患者。骨折根据AO/OTA系统分型：转子间二部分骨折分为A1型（稳定骨折）,多部分骨折为A2型（不稳定骨折）,反斜形转子间骨折为A3型（不稳定骨折）。比较2组在手术时间、出血量、术后卧床时间、并发症发生率及术后1年病死率、Harris功能评分、人工关节松动率、住院时间等方面的指标。结果 75例均获得16~24个月随访,43例PFNA组骨折均顺利愈合;32例半髋关节置换假体无脱位、假体柄无明显下沉。两组术后髋关节功能优良率、内置物并发症差异不明显（P〉0.05）,但半髋关节置换组内科并发症更少（P〈0.05）、切口长度较大（P〈0.05）、手术时间较长（P〈0.05）、术中出血量较多（P〈0.05）、术后卧床时间及下地时间较短（P〈0.05）。结论双极人工股骨头置换术和PFNA内固定术均是治疗高龄患者粗隆间不稳定骨折的有效方法。双极人工股骨头治疗高龄伴严重骨质疏松的不稳定型股骨粗隆间骨折,下床活动早、早期并发症发生率低、功能恢复满意,可明显提高患者的生活质量。     

The Efficacy of Suture Fixation of the Greater Trochanter in Unstable Intertrochanteric Fractures

BackgroudIntertrochanteric fractures are one of the most common fractures in the elderly, especially those having osteoporosis. Stable intertrochanteric fractures may be fixed with implants including the dynamic hip screw and proximal femoral nail antirotation; however, this method is difficult to apply to unstable fractures. Bipolar hemiarthroplasty can be applied to unstable fractures and it prevents complications by facilitating early ambulation in the elderly. Many studies reported on how to fix the greater trochanter in unstable fractures during arthroplasty. We suggest that suture fixation alone can be a useful, effective, and affordable method.MethodsWe retrospectively enrolled 294 patients who underwent hemiarthroplasty for an unstable intertrochanteric fracture, and 225 patients were included in this study after excluding 69 patients who had not been available for follow-up until 1 year after surgery or died. The patients were divided into suture fixation and wiring fixation groups. Relationships of operation time, estimated blood loss, tip-to-stem distance, union rate, and physical performance in the groups of suture fixation and wiring were analyzed respectively.ResultsChanges in the tip-to-stem distance between the initial assessment at 1 year after surgery were statistically significantly different between the suture fixation group and wiring group (p < 0.001). There was no significant difference in change of the Koval score between the suture fixation and wiring groups (p = 0.362). The operation time and estimated intraoperative blood loss were statistically significantly lower in the suture group than in the wiring group (p < 0.001). There was no significant difference in the union rate between the groups (p = 0.470).ConclusionsCompared to tension-band wiring, the suture fixation technique demonstrated an effective fixing force. In addition to the clinical results, it had an advantage of preventing complications due to shortening of the operation time and estimated intraoperative blood loss. Suture fixation of the greater trochanter is recommended for elderly patients with unstable intertrochanteric fractures.     

Frakturendoprothetik der medialen Schenkelhalsfraktur

A paradigm shift in the treatment of elderly patients has recently taken place leading to an increase in joint replacement surgery. The aim of this article is to highlight new developments and to present a treatment algorithm for femoral neck fractures. The age limit must be individually determined considering the comorbidities and perioperative risk profile. Pertrochanteric femoral fractures are nearly exclusively treated by osteosynthesis regardless of age. The situation for femoral neck fractures is more complex. Patients younger than 65 years should generally be treated by osteosynthesis but patients older than 65 years benefit from hemiarthroplasty or total hip arthroplasty. In patients aged between 65 and 75 years with high functional demands and a justifiable perioperative risk, total joint replacement is the treatment of choice. In physically less active patients older than 75 years and poor general condition, preference should be given to hemiarthroplasty.     

On-Table and Short-Term Mortality: A Single-Institution Experience With Cementing All Hip Arthroplasties for Neck of Femur Fractures

BackgroundTo review on-table, day 0, day 1, day 7, and day 30 mortality after hemiarthroplasty or total hip arthroplasty (THA) using cemented femoral stems for femoral neck fractures in order to evaluate risk factors for perioperative and short-term mortality.MethodsThe medical records of 751 consecutive cases with neck of femur fractures who underwent hemiarthroplasty (n = 602) or THA (n = 149) with cemented stems between January 2011 and December 2016 were retrospectively reviewed from a prospectively gathered database. The primary outcome measures were on-table, day 0, day 1, day 7, and day 30 mortality. Univariate and multivariate analyses were performed in order to identify various contributing patient and surgical variables.ResultsThere were 2 on-table deaths (0.27%): one patient had a cardiorespiratory arrest at the time of inserting the femoral stem and the other had a cardiorespiratory arrest at the end of wound closure some 20 minutes after cementing. There were 3 further day 0 deaths meaning the day 0 mortality rate was 0.67% (5/751). All 5 patients were older than 80 years and had an American Society of Anesthesiologists grade 3 or more. The 1-day, 7-day, and 30-day mortality rates were 0.93% (7 patients), 2.7% (20 patients), and 6.8% (51 patients), respectively. There is significantly higher 30-day mortality risk associated with increasing American Society of Anesthesiologists grade (P < .001) when adjusted for age, gender, and type of surgery (hemiarthroplasty compared with THA).ConclusionIn our neck of femur fracture patients who were operated with cemented stems, 7-day and 30-day mortality rates were 2.7% and 6.8%, respectively. Cemented stems should be used with caution in elderly hip fracture patients with multiple comorbidities who are at high risk of perioperative mortality.     

加长柄人工股骨头置换术与PFNA内固定治疗高龄不稳定股骨粗隆间骨折的比较研究

Pre-injury use of antiplatelet and anticoagulations therapy are associated with increased mortality in a cohort of 1038 hip fracture patients

BackgroundHip fractures are a large burden on the health care systems of developed nations. Patients usually have multiple co-morbidities and the pre-injury use of anticoagulants and anti-platelet medication is common.Materials and methodsThis study used a single hospital hip fracture database to facilitate a retrospective analysis of the impact of anti-coagulation and anti-platelet therapy on mortality and complications after surgical management of hip fractures. There were 92 patients on warfarin, 69 on DOAC, 260 antiplatelet patients and 617 control patients.ResultsMortality rates at 30 days were 4.8% for the control group, 12.6% for the antiplatelet group, warfarin 7.0%, 9.5% for Direct Oral Anticoagulant (DOAC) group, p = 0.004. Mortality rates at 1 year were 22.4% for the control group, 32.3% for the antiplatelet group, 29.3% for the warfarin group and 29.0% for DOAC group (p=0.007).Amongst complications, significant differences were found in transfusion (DOAC) and wound ooze (warfarin) rates, but the study did not detect significant clinical consequences arising from these differences.A matched analysis for age, sex, and ASA was undertaken to look in more detail at mortality data. Some mortality differences remained between groups with anti-platelet medication associated with increased mortality, but the differences no longer appeared to be significant.Our data suggests that this is a non-causal association, which could be incorporated into predictive mortality risk scores such as the Nottingham hip fracture score.ConclusionWe believe that pre-injury antiplatelet therapy is a strong indicator for high risk patients with higher expected mortality after hip fracture surgery. We saw no evidence to support delayed surgery in patients taking DOACs     

Joint proprioception in the elderly with and without hip fracture

OBJECTIVES: Decreased proprioception may contribute to the risk of falls in elderly patients. The purpose of this study is to determine whether patients with hip fractures have decreased hip proprioception compared with aged-matched controls, and whether hip proprioception differs in patients with repaired fractures compared with patients who have undergone prosthetic hip replacement after hip fracture. DESIGN: Retrospective. PATIENTS/PARTICIPANTS: Both hips of twenty-four hip fracture patients and age-matched patients without hip fractures were studied. Hip fracture patients were divided into osteosynthesis (twelve hips) and hemiarthroplasty (twelve hips) groups. INTERVENTION: Reproducibility of index angles (thirty hip flexion and thirty hip abduction) were compared with a six-degree-of-freedom electrogoniometer (instrumented spatial linkage; angular accuracy +/-0.5 degrees). RESULTS: There was no significant difference (flexion, p > 0.20; abduction, p > 0.67) in joint proprioception between fracture and no fracture groups. Likewise, there was no difference (flexion, p > 0.99, abduction; p > 0.74) in joint proprioception between osteosynthesis and hemiarthroplasty groups. CONCLUSIONS: Joint proprioception of hip fracture patients was not found to be diminished compared with age-matched normal controls. Additionally, replacement of the femoral head did not reduce joint proprioception compared with osteosynthesis with an intact femoral head. Maintenance of the femoral head does not seem to be necessary for the maintenance of joint proprioception in elderly hip fracture patients.     

比较两种假体半髋置换治疗高龄不稳定转子间骨折

目的比较骨水泥型与生物型双极人工股骨头置换术治疗高龄不稳定性股骨转子间骨折的临床疗效。 方法2013年1月至2017年1月,凉山州第一人民医院共收治94例高龄不稳定性股骨转子间骨折患者,分别采用骨水泥型股骨假体(骨水泥组,51例)或生物型股骨假体(生物组,43例)行双极人工股骨头置换术。所有患者均获得随访,随访终点时间为12个月或患者死亡。采用t检验或卡方检验比较两组患者临床疗效。 结果两组患者术前一般资料比较,差异均无统计学意义(均为P>0.05)。骨水泥组患者术后伤口引流量(t＝3.964,P<0.05)及输血量(t＝5.245,P<0.05)均较生物组低,而手术时间较长(t＝3.535,P<0.05)。两组术中失血量、术后住院天数、术后下地活动时间、并发症、髋关节功能、及术后3个月和12个月死亡率比较,差异均无统计学意义(均为P>0.05)。所有患者均无假体松动需要翻修。 结论采用半髋置换术治疗高龄不稳定性股骨转子间骨折,可获得满意的临床疗效;骨水泥型假体具有降低术后引流量及输血量的优点,同时增加手术时间的缺点。
