Hemiarthroplasty versus internal fixation for displaced intracapsular hip fractures: A long-term follow-up of a randomised trial

In a prospective randomised trial, 455 patients presenting to one hospital with a displaced intracapsular fracture were randomised to either closed reduction and internal fixation with three cancellous screws or replacement with an uncemented hemiarthroplasty. Follow-up of surviving patients was for between 9 and 15 years to determine the long-term outcome for the two treatment methods. 93% of patients died during this follow-up period. There was no difference in mortality between the two procedures. The need for revision surgery to the hip was increased for those treated by internal fixation (93% versus 62% implant survival rate; hazard ratio: 0.14, 95% CI 0.08-0.24). 91% of revision's operations occurred within 2 years from injury. There was no difference in the degree of residual pain between groups neither was there any difference in the number of patients requiring institutional care. These results demonstrate that both treatment methods produce comparable final outcomes but internal fixation is associated with an increased re-operation rate.     

Prehospital fast track care for patients with hip fracture: Impact on time to surgery,hospital stay,post-operative complications and mortality a randomised,controlled trial

IntroductionAmbulance organisations in Sweden have introduced prehospital fast track care (PFTC) for patients with suspected hip fracture. This means that the ambulance nurse starts the pre-operative procedure otherwise implemented at the accident & emergency ward (A&E) and transports the patient directly to the radiology department instead of A&E. If the diagnosis is confirmed, the patient is transported directly to the orthopaedic ward. No previous randomised, controlled studies have analysed PFTC to describe its possible advantages.The aim of this study is to examine whether PFTC has any impact on outcomes such as time to surgery, length of stay, post-operative complications and mortality.MethodsThe design of this study is a prehospital randomised, controlled study, powered to include 400 patients. The patients were randomised into PFTC or the traditional care pathway (A&E group).ResultsTime from arrival to start for X-ray was faster for PFTC (mean, 28 vs. 145 min; p < 0.001), but the groups did not differ with regard to time from start of X-ray to start of surgery (mean 18.40 h in both groups). No significant differences between the groups were observed with regard to: time from arrival to start of surgery (p = 0.07); proportion operated within 24 h (79% PFTC, 75% A&E; p = 0.34); length of stay (p = 0.34); post-operative complications (p = 0.75); and 4 month mortality (18% PFTC, 15% A&E p = 0.58).ConclusionPFTC improved time to X-ray and admission to a ward, as expected, but did not significantly affect time to start of surgery, length of stay, post-operative complications or mortality. These outcomes were probably affected by other factors at the hospital. Patients with either possible life-threatening conditions or life-threatening conditions prehospital were excluded.     

Short versus long thread cannulated cancellous screws for intracapsular hip fractures: A randomised trial of 432 patients

It is unclear which length of thread may be most advantageous for the internal fixation of an intracapsular fracture with cancellous screws. We have compared the 16 mm versus the 32 mm threads on cancellous screws within a randomised trial for 432 patients. All fractures were fixed with three screws and patients followed-up for a minimum of one year from injury.The characteristics of the patients in the two groups were similar with a mean age of 76 years. 23% were male. The most common complication encountered was non-union of the fracture which for undisplaced fractures occurred in 7/107 (6.5%) of short threaded screws versus 11/133 (8.3%) of long threaded screws. For displaced fractures the figures were 29/104 (27.9%) versus 24/89 (27.0%). Other complications for the short versus long threaded group were avascular necrosis (two cases versus five cases) and fracture below the implant (two cases in each group). Elective removal of the screws for discomfort was undertaken in five and three cases, respectively. None of these differences between groups was statistically significant. In summary there is no difference in fracture healing complications related to the length of the screw threads.     

Sliding hip screw versus intramedullary nail for trochanteric hip fractures; a randomised trial of 1000 patients with presentation of results related to fracture stability

AimsTo determine the optimum choice of implant for a patient with a the different types of trochanteric hip fracture.Patients and methods1000 patients with a trochanteric hip fracture were randomised to internal fixation of the fracture with either a Sliding Hip Screw or an intramedullary nail. Fractures were subdivided into two part fractures, comminuted fractures and fractures at the level of the lesser trochanter (reversed/oblique and transverse). Functional assessment for up to one year from injury was undertaken by a research nurse blinded to the treatment allocation.ResultsThe mean age of patients was 82 years and 77% were female. There was a significantly improved regain of mobility for those treated with the intramedullary nail. No statistically significant differences between the two types of fixation methods was observed for mortality, fracture healing complications, re-operations, hospital stay, length of surgery, blood transfusion requirements, medical complications, degree of residual pain or regain of independence. These finding were valid for all fracture types.ConclusionThis study is the first adequately powered randomised trial on this topic and demonstrates that there are no notable differences in either process or functional outcomes between these two treatment methods, other than a tendency to better regain of mobility for those fractures fixed with an intramedullary nail.     

Recovery after hip fracture

OBJECTIVES: The aim was to monitor the inhospital progress of 170 patients sustaining proximal femoral fractures. The extent of delay in discharge was recorded and what effect this prolonged hospitalisation had on nosocomial infection rates. SETTING: A regional trauma centre. DESIGN: A prospective observational study. PATIENTS AND PARTICIPANTS: All consecutive patients sustaining proximal femoral fracture over 60 years of age. INTERVENTION: The same clinician monitored each patient throughout their inhospital stay. Factors recorded included nosocomial infection acquired and when, mobility scores, loss of independence, delay in discharge amongst others. MAIN OUTCOME: Delay in discharge, incidence of nosocomial infection and mobility scores. RESULTS: Nosocomial infection occurred in 58% of patients (99 patients) when discharge was delayed beyond 8 days (after surgery). Eighty-five per cent of patients (145 patients) achieved their maximum mobility score by the 8th, and 95% (162 patients) by the 10th postoperative day. CONCLUSIONS: Patients with proximal femoral fracture derive no benefit from acute hospital admission of more than 8 days and the majority acquire nosocomial infection after this.     

The hidden blood loss after hip fracture

Introduction

Despite advances in surgical and anaesthetic techniques the mortality after hip fracture has not significantly changed in the last 40 years. Pre-operative anaemia is a risk factor for peri-operative death.We speculate that a significant proportion of the blood loss related to hip fractures has occurred prior to surgery. Identifying patients at risk of pre-operative anaemia can facilitate appropriate medical optimisation. This study is unique in its attempt to quantify the blood loss associated with the initial hip injury.

Methods

In a retrospective study all patients with both a diagnosis of hip fracture and an operative delay of >48 h were assessed. The information collected included: fracture classification, serial haemoglobins and patient co-morbidities. The exclusion criteria included a pre-injury diagnosis of anaemia, anti-coagulation and gastrointestinal bleeds.

Results

Between 2007/2008 sixty-eight intracapsular and fifty extracapsular hip fracture patients had serial haemoglobins and operative delays of >48 h (mean 75 h, range 48-270 h). The mean lowest recorded haemoglobin prior to surgery for both extracapsular and intracapsular fractures were 95.0 g/L (±SEM 2.2) and 108.5 g/L (±SEM 2.2) respectively. This difference was statistically significant (Student's t-test p < 0.05).The mean haemoglobin drop in the extracapsular and intracapsular fracture groups was 20.2 g/L (range 0-49 g/L) and 14.9 g/L (range 0-59 g/L) respectively.

Conclusions

Hip fracture patients have a large drop in haemoglobin that is associated with the initial trauma rather than the operation. This highlights the need for anaesthetic and orthopaedic staff to be vigilant to the risk of pre-operative anaemia in this cohort of frail patients even when the initial haemoglobin is apparently normal.     

Clopidogrel therapy--implications for hip fracture surgery

It remains unclear whether it is justifiable to delay hip fracture surgery in patients who are taking clopidogrel therapy-to allow the drug's anti-platelet effect to wear off. In a follow-up of 740 consecutive admissions with hip fracture we describe the extent of blood loss and complications in 17 (2.3%) who were taking clopidogrel. The peri-operative fall in haemoglobin was 1.3g/dl (95% CI: 0.4-2.3g/dl) less in the 10 patients in whom the surgeon's policy was for surgery to be delayed for at least 5 days. However, this group also experienced thromboembolic complications that were potentially attributable to this approach. Clopidogrel therapy does have implications for peri-operative blood loss, but hip fracture is a complex and multifactorial condition. We propose an individualised approach to patients taking this increasingly common drug.     

Comparison of the postoperative analgesic efficacies of intravenous acetaminophen and fascia iliaca compartment block in hip fracture surgery: A randomised controlled trial

BackgroundManaging pain during movement after hip fracture surgery is important for achieving earlier hip mobilisation and for preventing postoperative complications. In the present study, we tested the hypothesis that the fascia iliaca compartment block (FICB) would improve postoperative pain on movement compared with intravenous acetaminophen.MethodsIn this prospective, randomised, controlled, parallel trial, patients were assigned to either the intravenous acetaminophen or the ultrasound-guided FICB group. Visual analog scale (VAS) pain scores were evaluated at 6, 9, 12, 18, 24 h, 2 days, and 7 days postoperatively. The primary outcome was VAS scores on movement at 24 h after surgery. The secondary outcomes were VAS scores on movement at the other time points, VAS scores at rest, the total number of rescue analgesics required and incidence of delirium during the first 24 h postoperatively, potential drug or block-related complications, and the time to first standing.ResultsVAS scores on movement at 24 h after surgery were significantly lower in the FICB group than in the intravenous acetaminophen group [median (the 25th to 75th percentiles), 20 (10–30) vs 40 (30–53); P < 0.01]. The VAS scores on movement at any other time point and the scores at rest at 12 h after surgery were also significantly lower in the FICB group than in the intravenous acetaminophen group. The two groups did not differ in terms of the total number of rescue analgesics required or the incidence of delirium during the first 24 h postoperatively; complications; or the time to first standing.ConclusionsFICB improved postoperative pain on movement compared with intravenous acetaminophen without increasing the complication rate. However, the total number of rescue analgesics required and the time to first standing were not significantly different between the two groups.     

Mobility after intertrochanteric hip fracture fixation with either a sliding hip screw or a cephalomedullary nail: Sub group analysis of a randomised trial of 1000 patients

AimsThe aim of this study was to determine if different patient groups have superior mobility regain following intertrochanteric hip fracture fixation with a cephomedullary nail compared to a sliding hip screw (SHS).Patients and methodsThe present study is a subgroup analysis of patients which were enrolled into a randomized controlled trial which randomized 1000 patients with an intertrochanteric hip fracture to fixation with either a short cephomedullary nail (Targon® PF or PFT) or a SHS. In the present study the two treatment groups were dicotomised on the basis of six variables determined at the time of admission; age (<80; ≥80 years), sex, residence (admitted from own home; institutional care), mobility (mobility score ≥7 [good]; <7 [poor]), mental status (AMTS < 7 [cognitively impaired]; ≥7) and health status (ASA < 3; ≥3). The primary outcome measure was the difference between mobility score pre-fracture and mobility score during the year after hip fracture fixation.ResultsPatients less than 80 years of age, those admitted from their own home, cognitively intact patients and patients who mobilised without assistance pre-fracture, recovered superior mobility when fracture fixation was performed with a nail compared to a SHS. Those patients admitted from institutional care, those with significant cognitive or mobility impairment at the time of the injury did not have any significantly improved benefit in mobility regain with a nail compared to a SHS.ConclusionFixation of an intertrochanteric hip fracture with a cephomedullary nail results in superior recovery of mobility for younger patients who prior to the injury were more mobile, cognitively intact and living at home.     

Survival after hip fracture

Although it is known that overall mortality is increased after hip fracture, the influence of hip fracture risk factors on the subsequent mortality and cause of death has not been well studied. The objective of this study was to establish the survival after hip fracture in women and to assess the impact of comorbidity on mortality. We identified a complete population-based set of 2,245 incident hip fracture cases and 4,035 randomly selected population-based controls among women 50–81 years old in Sweden and followed these subjects for an average of 5 years through the Swedish National Inpatient and Cause-of-Death Registers. Information on factors related to hip fracture was obtained through linkage to hospital discharge data and through a mailed questionnaire. We studied excess mortality of hip fracture patients compared to controls using survival curves and proportional hazard regression models. During follow-up, 896 hip fracture patients (40%) and 516 (13%) controls died. The relative risk (RR) of death, adjusted for age and previous hospitalization for serious disease, was 2.3 (95% CI 2.0–2.5). Although the highest mortality risks were in the 1st 6 months post-fracture, RRs for fractures versus controls were increased for at least 6 years. Increased mortality was apparent both in those with evidence of comorbidity and those without. Hip fracture patients have a substantially increased risk of death that persists for at least 6 years post-fracture. The relative excess mortality is independent of comorbidity and known hip fracture risk factors.The authors represent the Swedish Hip Fracture Study Group, whose members include Akke Alberts, John A.

Feasibility of progressive strength training shortly after hip fracture surgery

AIM: To investigate the feasibility of a 6-wk progressive strength-training programme commenced shortly after hip fracture surgery in community-dwelling patients.METHODS: This prospective, single-blinded cohort study evaluated 31 community-dwelling patients from four outpatient geriatric health centres aged 60 years or older, who started a 6-wk programme at a mean of 17.5 ± 5.7 d after hip fracture surgery. The intervention consisted primarily of progressive fractured knee-extension and bilateral leg press strength training (twice weekly), with relative loads commencing at 15 and increasing to 10 repetitions maximum (RM), with three sets in each session. The main measurements included progression in weight loads, hip fracture-related pain during training, maximal isometric knee-extension strength, new mobility score, the timed up and go test, the 6-min walk test and the 10-meter fast speed walk test, assessed before and after the programme.RESULTS: Weight loads in kilograms in the fractured limb knee-extension strength training increased from 3.3 ± 1.5 to 5.7 ± 1.7 and from 6.8 ± 2.4 to 7.7 ± 2.6, respectively, in the first and last 2 wk (P < 0.001). Correspondingly, the weight loads increased from 50.3 ± 1.9 to 90.8 ± 40 kg and from 108.9 ± 47.7 to 121.9 ± 54 kg in the bilateral leg press exercise (P < 0.001). Hip fracture-related pain was reduced, and large improvements were observed in the functional outcome measurements, e.g., the 6-min walk test improved from 200.6 ± 79.5 to 322.8 ± 68.5 m (P < 0.001). The fractured limb knee-extension strength deficit was reduced from 40% to 17%, compared with the non-fractured limb. Ten patients reported knee pain as a minor restricting factor during the last 10 RM knee-extension strength-training sessions, but with no significant influences on performance.CONCLUSION: Progressive strength training, initiated shortly after hip fracture surgery, seems feasible and does not increase hip fracture-related pain. Progressive strength training resulted in improvement, although a strength deficit of 17% persisted in the fractured limb compared with the non-fractured limb.     

Effect of blood transfusion on survival after hip fracture surgery

Background

Our primary goal was to audit the incidence of erythrocyte blood transfusion (EBT) after hip fracture surgery and study the effects on perioperative complications and early and late mortality.

Methods

In a retrospective cohort study all patients 65 years old and above treated operatively for an acute hip fracture were included over a 48-month period with a 2-year follow-up period. Postoperative hemoglobin levels were used to investigate at what threshold EBT was used. The relation between EBT and perioperative complications and survival was analyzed with multivariate regression analysis. A propensity score for predicting the chance of receiving an EBT was calculated and used to differentiate between transfusion being a risk factor for mortality and other related confounding risk factors. Mortality was subdivided as in-hospital, 30-day, 1-year and 2-year mortality.

Results

Of the 388 included patients, 41% received a blood transfusion. The postoperative hemoglobin level was the strongest predictor for EBT. Patients who received EBT had a significant longer hospital stay and more postoperative cardiac complications, even after adjustment for confounders. Multivariate analysis for mortality showed that EBT was a significant risk factor for early as well as late mortality, but after adding the propensity score, EBT was no longer associated with increased mortality.

Conclusion

There was no effect of EBT on mortality after correction with propensity scoring for predictors of EBT. Transfusion in patients treated operatively for hip fracture should be evenly matched with their cardiovascular risk during the perioperative phase.

     

The weekend effect for hip fracture surgery

IntroductionIncreased mortality rates have been reported for emergency admissions during weekends and outside office hours. Research on the weekend effect in hip fracture patients is however limited and demonstrates conflicting results. The aim of this study was to determine the effect of weekend admission and weekend surgery on 30-day and 1-year mortality following hip fracture surgery.Patients and methodsAll patients who underwent hip fracture surgery in our hospital between 2004 and 2015 were included in this retrospective study. Patient characteristics including age, gender, fracture type, American Society of Anesthesiologists (ASA) score, Nottingham Hip Fracture Score (NHFS), Charlson Comorbidity Index (CCI) and length of stay were collected. Information on admission and surgery date and time of day was recorded, as were in-hospital, 30-day and 1-year mortality. Multivariable logistic regression analysis was performed to identify independent predictors of 30-day and 1-year mortality.ResultsA total of 1803 patients were included, 546 patients (30.3%) were admitted during the weekend. Patient characteristics did not differ between weekday and weekend admissions. Surgical delay was less frequent in patients undergoing weekend surgery. Multivariable analysis demonstrated that older age, higher ASA score, higher NHFS and increased surgical delay were independently associated with 30-day mortality. One-year mortality was associated with age, gender, ASA score, CCI and surgical delay. Weekend admission and weekend surgery were not associated with increased 30-day or 1-year mortality.ConclusionsThere was no weekend effect for hip fracture patients in our study. These results indicate an adequate level of perioperative care outside weekday office hours within our health care system.

The effect of clopidogrel and aspirin on blood loss in hip fracture surgery

Introduction

Anti-platelet drugs are commonly used for primary and secondary prevention of thrombo-embolic events and following invasive coronary interventions. Their effect on surgery-related blood loss and perioperative complications is unclear, and the management of trauma patients treated by anti-platelets is controversial. The anti-platelet effect is over in nearly 10 days. Notably, delay of surgical intervention for hip fracture repair for >48 h has been reported to increase perioperative complications and mortality.

Patients and methods

Intra-operative and perioperative blood loss, the amount of transfused blood and surgery-related complications of 44 patients on uninterrupted clopidogrel treatment were compared with 44 matched controls not on clopidogrel (either on aspirin alone or not on any anti-platelets).

Results

The mean perioperative blood loss was 899 ± 496 ml for patients not on clopidogrel, 1091 ± 654 ml for patients on clopidogrel (p = 0.005) and 1312 ± 686 ml for those on combined clopidogrel and aspirin (p = 0.0003 vs. all others). Increased blood loss was also associated with a shorter time to operation (p = 0.0012) and prolonged surgical time (p = 0.0002). There were no cases of mortality in the early postoperative period.

Conclusions

Patients receiving anti-platelet drugs can safely undergo hip fracture surgery without delay, regardless of greater perioperative blood loss and possible thrombo-embolic/postoperative bleeding events.

Predictors of 30-day hospital readmission after hip fracture: a systematic review

BackgroundEarly readmission to hospital after hip fracture is associated with increased mortality and significant costs to the healthcare system. There is growing interest in the use of 30-day readmission rates as a metric of hospital performance. Identifying patients at increased risk of readmission after hip fracture may enable pre-emptive action to mitigate this risk and the development of effective methods of risk-adjustment to allow readmission to be used as a reliable measure of hospital performance.MethodsWe conducted a systematic review of bibliographic databases and reference lists up to July 2016 to identify primary research papers assessing the effect of patient- and hospital-related risk factors for 30-day readmission to hospital after hip fracture.Results495 papers were found through electronic and reference search. 65 full papers were assessed for eligibility. 22 met inclusion criteria and were included in the final review.Medical causes of readmission were significantly more common than surgical causes, with pneumonia consistently being cited as the most common readmission diagnosis. Age, pre-existing pulmonary disease and neurological disorders were strong independent predictors of readmission. ASA grade and functional status were more robust predictors of readmission than the Charlson score or individual co-morbidities. Hospital-related risk factors including initial length of stay, hospital size and volume, time to surgery and type of anaesthesia did not have a consistent effect on readmission risk. Discharge location and the strength of hospital-discharge facility linkage were important determinants of risk.ConclusionsPatient-related risk factors such as age, co-morbidities and functional status are stronger predictors of 30-day readmission risk after hip fracture than hospital-related factors. Rates of 30-day readmission may not be a valid reflection of hospital performance unless a clear distinction can be made between modifiable and non-modifiable risk factors. We identify a number of deficiencies in the existing literature and highlight key areas for future research.

Impact of length of red blood cells transfusion on postoperative delirium in elderly patients undergoing hip fracture surgery: A cohort study

PurposeThe purpose of the present study was to test whether older red blood cells (RBCs) transfusion results in an increased risk of postoperative delirium (POD) and various in-hospital postoperative complications in elderly patients undergoing hip fracture surgery.Materials and methodsPatients (≥65 years) who underwent hip fracture surgery were enrolled, 179 patients were divided into two groups according to the storage time of the RBCs. The shorter storage time of RBCs transfusion group comprised patients who received RBCs ≤14 days old and the longer storage time of RBCs transfusion group comprised patients who received RBCs >14 days old. The blood samples were collected before anaesthesia induction, 4 and 24 h after RBCs transfusion for the determination of proinflammatory mediators, malondialdehyde, and superoxide dismutase activity.ResultsThere was no difference in the baseline characteristics, the incidence of POD, and the in-hospital postoperative complications between the shorter storage time of RBCs transfusion group and the longer storage time of RBCs transfusion groups (P > 0.05). Compared with the shorter storage time of RBCs transfusion group, the longer storage time of RBCs transfusion caused significantly longer duration of POD (P < 0.05). There were significantly increased plasma levels of IL-8 and malondialdehyde at 24 h and IL-1β at 4 h after RBCs transfusion in the POD group compared with the non-POD group (P < 0.05).ConclusionTransfusion of the longer storage RBCs is not associated with a higher incidence of POD or in-hospital postoperative complications, but with longer duration of POD in elderly patients undergoing hip fracture surgery.
