Extracapsular Hip Fractures (EHF's) are a significant health burden on healthcare services. Optimal treatment is controversial with conflicting evidence being reported. Currently treatment is undertaken with Intramedullary Nail (IMN) or Dynamic Hip Screw (DHS) constructs with a recent increase in IMN use (1). This study aims to conduct a systematic review of Randomised Control Trials published between 2020 and 2023 with particular focus on patient demographics and holistic patient outcomes. Using a unified search-protocol, RCT's published between 2020 and 2023 were collected from CENTRAL, PubMed, MEDLINE and EMBASE. Rayyan software screened duplicates. Using the CASP and Cochrane Risk of Bias Tool papers were critically examined twice, and Blood Loss, Infection and Mobility described the patient journey. Patient demographics were recorded and were contrasted with geographically diverse cohort studies to compare population differences. Parametric tests were used to determine significance levels between population demographics, namely Age and Sex. Eleven papers were included, representing 908 patients (436 Male). The mean age for patients was 64.39. There was considerable risk of bias in 7/11 studies owing to the randomization process and the recording of data. Four Cohort studies were selected for comparison representing 14314 patients. Mean age was significantly different between Cohort Studies and RCT's (Independent T-Test, df 13, t=7.8, p = <0.001, mean difference = 19.251, 95% CI = 13.888, 24.613). This was also true for sex ratios included in the studies (df 13, t = -2.268, p = 0.024, Mean Difference = -0.4884, 95% CI = -0.9702, -0.0066). To conclude, RCT's published in the post COVID-19 era are not representative of patient demographics. This has the potential to provide inaccurate information for implant selection. Additionally further research must be conducted in how to better improve RCT patient inclusion so as to be more representative of patients whilst balancing the risks of operations

Patients undergoing total hip or knee arthroplasty (THA/TKA) are commonly associated with high pain scores and narcotic use. Duloxetine is effective in relieving chronic pain. The aim of this study was to evaluate the safety and efficacy of duloxetine for pain management following THA/TKA.

Five major databases (PubMed, Embase, Scopus, Cochrane, and Web of Science) were searched for randomised controlled trials (RCTs) that compared duloxetine to placebo in patients that underwent THA/TKA. The primary outcome was pain reduction with rest and movement at short-term and long-term time intervals. Secondary outcomes were the use of analgesics, length of stay, and safety profile. The risk of bias was assessed using the Cochrane tool. Data were pooled using RevMan 5.4. The results were reported as mean difference (MD) or standardised MD (SMD) and 95% confidence intervals (CI).

Eight RCTs with 767 patients were included. 50.2% (n=385/767) of patients received duloxetine. After one day, duloxetine was superior to the control regarding pain reduction with rest (SMD= −0.22 [−0.41, −0.03], p=0.02) after sensitivity analysis and pain reduction at movement (SMD= −0.39 [−0.55, −0.24], p<0.001). Similarly, after 12 weeks, duloxetine significantly reduced pain with rest (SMD= −0.3 [−0.52, −0.09], p=0.006) and pain with movement (SMD= −0.52 [−0.87, −0.17], p=0.003). In addition, after sensitivity analysis, duloxetine was associated with less analgesic use after one day (MD= −4.65 [−7.3, −2.01], p<0.001) and two days (MD= −5.65 [−10.62, −0.67], p=0.03). Patients who received duloxetine also required fewer analgesics after three days. However, there was no significant difference between the duloxetine and control groups in analgesic use after one week, length of stay, and adverse events.

Duloxetine was superior to the placebo regarding short-term and long-term pain reduction with rest and movement following THA/TKA. Duloxetine reduced postoperative analgesic use. There was no significant difference between duloxetine and placebo regarding adverse events and length of stay.

Hip resurfacing remains a safe and effective option according to registry data. Results in women were less reliable, in part owing to soft tissue impingement. Biolox Delta ceramic bearing couples are now in widespread use with very low complication rates. We set about merging these three elements to develop a novel hip resurfacing arthroplasty.

Contours of both acetabular and femoral components were generated from biometric data, adapted to the constraints of ceramic machining, to ensure that radii blended from the bearing surface avoiding any sharp boundaries. Plasma spray coating with titanium and hydroxyapatite direct onto ceramic was developed and tested using shear, tensile and taber abrasion testing. Wear testing was carried out to 5 million cycles according to the ASTM. Destructive testing was carried out in a variety of test conditions and angles.

Cadaveric testing demonstrated stability using a single use disposable instruments for both conventional and patient specific procedures. Very low dose CT enabled the entire interface to be observed as the Ceramic is radiolucent, enhancing migration analysis, which will be undertaken at 4 intervals to confirm stability. Functional scores and gait analysis will be used in the safety study.

The CE study recruitment is underway, with first in human trials starting in summer 2017. PMA submission will follow the safety study. Commercial release of the device in Europe is unlikely before 2019, and in the USA may not be until 2027. The path to novel device development in 2017 is very costly in time and money.

Preoperative anaemia and intraoperative blood loss result in ∼90% of individuals being anaemic following hip and knee arthroplasty. Reducing blood loss offers the opportunity to improve outcomes and reduce the risk of transfusion and costs. This review's aim was to determine the effectiveness of drugs for preventing blood loss, and identify optimal dose, route, and timing of administration. Cochrane network meta-analysis of randomised controlled trials was conducted. Inclusion criteria: adults undergoing primary or revision elective hip or knee arthroplasty. Drugs studied: tranexamic acid (TXA), aprotinin, epsilon-aminocaproic acid, desmopressin, factor VIIa and XIII, fibrinogen, fibrin sealants, and non-fibrin sealants. Primary outcomes: need for allogenic blood transfusion, all• cause mortality (within 30 days). Secondary outcomes: mean number of transfusion episodes, re-operation, length of hospital stay and adverse events (DVT, PE, CVA, MI). 102 studies with 8418 participants. Trials included more women (63%). 47 studies (4398 participants) were included within the blood transfusion NMA. TXA given intra-articularly and orally at a total dose of greater than 3g pre-incision, intraoperatively and postoperatively ranked the highest, with anticipated absolute effect of 147 fewer transfusions per 1000 (53% chance ranking 1st) (relative risk(RR) 0.02, 95% credible interval(CrI) 0–0.31); moderate-certainty). Aprotinin (RR 0.59, 95%:CrI 0.36–0.86; low certainty evidence), fibrin (RR 0.86, CrI 0.25–2.93; very-low certainty) and EACA (RR 0.60, 95%:CrI 0.29–1.27; very-low certainty) were not shown to be as effective as TXA. TXA was the most effective drug for preventing bleeding in lower limb arthroplasty. Aprotinin and EACA were not as effective. Currently, the optimal dose, route and timing of administration of TXA is unclear. However, TXA given at higher doses and via mixed routes ranked higher in the treatment hierarchy. Oral TXA may be as effective as intavenous. There was no evidence of harm associated with higher doses of TXA

There are a number of patients in whom hip preservation surgery is not indicated as they have developed signs of early osteoarthritis, and nor can they have a hip replacement as they are too early in the disease process. The use of PRP in OA of the hip has not been studied systematically and this study concisely collates all the available data in the use of PRP in Hip OA. This systematic review and meta-analysis aimed to assess intra-articular platelet-rich plasma as a therapeutic intervention for hip osteoarthritis, including the duration of efficacy, influence of dose and composition of PRP, and the incidence of adverse effects. We performed literature searches on the MEDLINE, EMBASE, CINHAL, WEB OF SCIENCE, COCHRANE and SCOPUS databases, and PRSIMA guidelines were followed. Data was pooled using random effects meta-analysis. We assessed quality of the included studies using the Methodological Index for Non-Randomised Studies (MINORS) instrument, with an additional assessment for Randomised Controlled Trials with the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2). Eight studies were included in the analysis, with data from a total of 331 patients. PRP significantly reduced pain compared to baseline at multiple timepoints, with the greatest effect at 1–2mo follow-up. PRP only significantly improved function at the 1–2mo follow-up. A significantly larger reduction in pain was achieved with a single injection or PRP compared to multiple injections, a total injected dose of PRP <15mL compared to ≥15mL or using a leukocyte-poor PRP preparation compared to leukocyte-rich PRP. There were no lasting adverse effects. Low and moderate quality evidence suggests that PRP reduces pain and improves function at endpoint compared to baseline. Moderate quality evidence suggests a larger reduction in pain is achieved with a single injection of PRP compared to multiple injections, and low quality evidence attributes a larger reduction of pain with a total injected dose of PRP <15mL compared to ≥15mL or using leukocyte-poor PRP compared to leukocyte-rich PRP

Objectives. The objective of this study was to assess all evidence comparing the Thompson monoblock hemiarthroplasty with modular unipolar implants for patients requiring hemiarthroplasty of the hip with respect to mortality and complications. Methods. A literature search was performed to identify all relevant literature. The population consisted of patients undergoing hemiarthroplasty of the hip for fracture. The intervention was hemiarthroplasty of the hip with a comparison between Thompson and modular unipolar prostheses. Pubmed, Embase, CINAHL, Web of Science, PROSPERO and the Cochrane Central Register of Controlled Trials. The study designs included were randomised controlled trials (RCTs), well designed case control studies and retrospective or prospective cohort studies. Studies available in any language, published at any time until September 2015 were considered. Studies were included if they contained mortality or complications. Results. The initial literature search identified 4757 items for examination. Four papers were included in the final review. The pooled odds ratio for mortality was 1.3 (95% confidence Interval 0.78 to 2.46) favouring modular designs. The pooled odds ratio for post-operative complications was 1.1 (95% CI 0.79 to 1.55) favouring modular designs. Outcomes were reported at 12 or six months. These papers all contained potential sources of bias and significant clinical heterogeneity. Conclusion. The current evidence comparing monoblock versus modular implants in patients undergoing hemiarthroplasty is weak. Confidence intervals around the pooled odds ratios are broad and incorporate a value of one. Direct comparison of outcomes from these papers is fraught with difficulty and, as such, may well be misleading. A well designed randomised controlled trial would be helpful to inform evidence-based implant selection. Cite this article: A. L. Sims, A. J. Farrier, M. R. Reed, T. A. Sheldon.

Aims. The aim of this study was to investigate the outcomes of Vancouver type B2 and B3 fractures by performing a systematic review of the methods of surgical treatment which have been reported. Materials and Methods. A systematic search was performed in Ovid MEDLINE, Embase and the Cochrane Central Register of Controlled Trials. For inclusion, studies required a minimum of ten patients with a Vancouver type B2 and/or ten patients with a Vancouver type B3 fracture, a minimum mean follow-up of two years and outcomes which were matched to the type of fracture. Studies were also required to report the rate of re-operation as an outcome measure. The protocol was registered in the PROSPERO database. . Results. A total of 22 studies were included based on the eligibility criteria, including 343 B2 fractures and 167 B3 fractures. The mean follow-up ranged from 32 months to 74 months. . Of 343 Vancouver B2 fractures, the treatment in 298 (86.8%) involved revision arthroplasty and 45 (12.6%) were treated with internal fixation alone. A total of 37 patients (12.4%) treated with revision arthroplasty and six (13.3%) treated by internal fixation only underwent further re-operation. . Of 167 Vancouver B3 fractures, the treatment in 160 (95.8%) involved revision arthroplasty and eight (4.8%) were treated with internal fixation without revision. A total of 23 patients (14.4%) treated with revision arthroplasty and two (28.6%) treated only with internal fixation required re-operation. Conclusion. A significant proportion, particularly of B2 fractures, were treated without revision of the stem. These were associated with a higher rate of re-operation. The treatment of B3 fractures without revision of the stem resulted in a high rate of re-operation. This demonstrates the importance of careful evaluation and accurate characterisation of the fracture at the time of presentation to ensure the correct management. There is a need for improvement in the reporting of data in case series recording the outcome of the surgical treatment of periprosthetic fractures. We have suggested a minimum dataset to improve the quality of data in studies dealing with these fractures. Cite this article: Bone Joint J 2017;99-B(4 Supple B):17–25

Aims

The primary outcome was investigating differences in wear, as measured by femoral head penetration, between cross-linked vitamin E-diffused polyethylene (vE-PE) and cross-linked polyethylene (XLPE) acetabular component liners and between 32 and 36 mm head sizes at the ten-year follow-up. Secondary outcomes included acetabular component migration and patient-reported outcome measures (PROMs) such as the EuroQol five-dimension questionnaire, 36-Item Short-Form Health Survey, Harris Hip Score, and University of California, Los Angeles Activity Scale (UCLA).

Aims

This study reports the ten-year wear rates, incidence of osteolysis, clinical outcomes, and complications of a multicentre randomized controlled trial comparing oxidized zirconium (OxZr) versus cobalt-chrome (CoCr) femoral heads with ultra-high molecular weight polyethylene (UHMWPE) and highly cross-linked polyethylene (XLPE) liners in total hip arthroplasty (THA).

Introduction. Previous systematic reviews have shown that patients experience low physical activity levels following total hip replacement (THR). However no previous systematic reviews have examined the changes between pre- and post-operative physical activity levels. Methods. AMED, MEDLINE, EMBASE, CENTRAL, CINHAL, openSIGLE, . ClinicalTrials.gov. and UK Clinical Trials Gateway databases were searched to 19. th. May 2015. All study designs presenting data on physical activity at pre- and up to one-year post-operatively were included. Eligible studies were critically appraised using the Cochrane risk of bias tool (for randomised controlled trials (RCTs)) and the CASP tool (non-RCTs). Where possible, mean differences (MD) and 95% confidence intervals (CI) were calculated through meta-analyses. Results. From 3850 citations, 16 met the eligibility criteria; nine included in the meta-analysis. The quality of the evidence was graded low to moderate. There was no statistically significant difference in physical activity pre- to one year post-THR when assessed using: movement-related activity (MD: −0.08; 95% CI:- 1.60 to 1.44; I. 2. =0%; n=77), percentage of 24 hours spent walking (MD: −0.21; 95% CI: −1.36 to 0.93; I. 2. =12%; n=65), six minute walk test (MD: −60.85; 95% CI: −122.41 to 0.72; I. 2. =84%; n=113) or the cardiopulmonary exercise test (MD: −0.24; 95% CI: −1.36 to 0.87; I. 2. =0%; n=76). Discussion. There is no evidence to suggest that physical activity changes pre- compared to post-THR. The low methodological quality of the included papers means this finding should be viewed with caution. Further research is warranted to better understand the relationship between physical activity pre- and post-THR, as greater consideration may be needed to increase physical activity in this population post-operatively. Conclusion. Surprisingly, there is no significant change in physical activity following THR. Surgeons, physiotherapists and patients should consider how to increase and maintain physical activity levels to maximise the potential for wider-health benefits following THR

Aims

BoneMaster is a thin electrochemically applied hydroxyapatite (HA) coating for orthopaedic implants that is quickly resorbed during osseointegration. Early stabilization is a surrogacy marker of good survival of femoral stems. The hypothesis of this study was that a BoneMaster coating yields a fast early and lasting fixation of stems.

Aims

The aim of the HIPGEN consortium is to develop the first cell therapy product for hip fracture patients using PLacental-eXpanded (PLX-PAD) stromal cells.

Aims

This study aims to assess the feasibility of conducting a pragmatic, multicentre randomized controlled trial (RCT) to test the clinical and cost-effectiveness of an informal caregiver training programme to support the recovery of people following hip fracture surgery.

Aims

Highly polished stems with force-closed design have shown satisfactory clinical results despite being related to relatively high early migration. It has been suggested that the minimal thickness of cement mantles surrounding the femoral stem should be 2 mm to 4 mm to avoid aseptic loosening. The line-to-line cementing technique of the femoral stem, designed to achieve stem press-fit, challenges this opinion. We compared the migration of a highly polished stem with force-closed design by standard and line-to-line cementing to investigate whether differences in early migration of the stems occur in a clinical study.

Aims

Cement-in-cement revision of the femoral component represents a widely practised technique for a variety of indications in revision total hip arthroplasty. In this study, we compare the clinical and radiological outcomes of two polished tapered femoral components.

Aims

We aimed to investigate if the use of the largest possible cobalt-chromium head articulating with polyethylene acetabular inserts would increase the in vivo wear rate in total hip arthroplasty.

Aims

A typical pattern of blood loss associated with total hip arthroplasty (THA) is 200 ml intraoperatively and 1.3 l in the first 48 postoperative hours. Tranexamic acid (TXA) is most commonly given as a single preoperative dose only and is often withheld from patients with a history of thromboembolic disease as they are perceived to be “high-risk” with respect to postoperative venous thromboembolism (VTE). The TRanexamic ACid for 24 hours trial (TRAC-24) aimed to identify if an additional 24-hour postoperative TXA regime could further reduce blood loss beyond a once-only dose at the time of surgery, without excluding these high-risk patients.

Aims

The purpose of this study was to examine the efficacy and safety of carbazochrome sodium sulfonate (CSS) combined with tranexamic acid (TXA) on blood loss and inflammatory responses after primary total hip arthroplasty (THA), and to investigate the influence of different administration methods of CSS on perioperative blood loss during THA.

Aims

It has been suggested that the direct anterior approach (DAA) should be used for total hip arthroplasty (THA) instead of the posterior approach (PA) for better early functional outcomes. We conducted a value-based analysis of the functional outcome and associated perioperative costs, to determine which surgical approach gives the better short-term outcomes and lower costs.

Aims

The aim of this study was to determine whether national standards of best practice are associated with improved health-related quality of life (HRQoL) outcomes in hip fracture patients.
