Aims

The tibial component of total knee arthroplasty can either be an all-polyethylene (AP) implant or a metal-backed (MB) implant. This study aims to compare the five-year functional outcomes of AP tibial components to MB components in patients aged over 70 years. Secondary aims are to compare quality of life, implant survivorship, and cost-effectiveness.

Aims

Arthroplasties of the elbow, including total elbow arthroplasty, radial head arthroplasty, distal humeral hemiarthroplasty, and radiocapitellar arthroplasty, are rarely undertaken. This scoping review aims to outline the current research in this area to inform the development of future research.

Aims

The aims of this study were to assess mapping models to predict the three-level version of EuroQoL five-dimension utility index (EQ-5D-3L) from the Oxford Knee Score (OKS) and validate these before and after total knee arthroplasty (TKA).

Aims

The purpose was to compare operative treatment with a volar plate and nonoperative treatment of displaced distal radius fractures in patients aged 65 years and over in a cost-effectiveness analysis.

Aims. A pragmatic multicentre randomized controlled trial, UK FROzen Shoulder Trial (UK FROST), was conducted in the UK NHS comparing the cost-effectiveness of commonly used treatments for adults with primary frozen shoulder in secondary care. Methods. A cost utility analysis from the NHS perspective was performed. Differences between manipulation under anaesthesia (MUA), arthroscopic capsular release (ACR), and early structured physiotherapy plus steroid injection (ESP) in costs (2018 GBP price base) and quality adjusted life years (QALYs) at one year were used to estimate the cost-effectiveness of the treatments using regression methods. Results. ACR was £1,734 more costly than ESP ((95% confidence intervals (CIs) £1,529 to £1,938)) and £1,457 more costly than MUA (95% CI £1,283 to £1,632). MUA was £276 (95% CI £66 to £487) more expensive than ESP. Overall, ACR had worse QALYs compared with MUA (-0.0293; 95% CI -0.0616 to 0.0030) and MUA had better QALYs compared with ESP (0.0396; 95% CI -0.0008 to 0.0800). At a £20,000 per QALY willingness-to-pay threshold, MUA had the highest probability of being cost-effective (0.8632) then ESP (0.1366) and ACR (0.0002). The results were robust to sensitivity analyses. Conclusion. While ESP was less costly, MUA was the most cost-effective option. ACR was not cost-effective.

Aims

Chronic low back pain due to degenerative disc disease is sometimes treated with fusion. We compared the outcome of three different fusion techniques in the Swedish Spine Register: noninstrumented posterolateral fusion (PLF), instrumented posterolateral fusion (IPLF), and interbody fusion (IBF).

Aims

This 501-patient, multi-centre, randomised controlled trial sought to establish the effect of low-intensity, pulsed, ultrasound (LIPUS) on tibial shaft fractures managed with intramedullary nailing. We conducted an economic evaluation as part of this trial.

Aims. A pragmatic multicentre randomised controlled trial (PROFHER) was conducted in United Kingdom National Health Service (NHS) hospitals to evaluate the clinical effectiveness and cost effectiveness of surgery compared with non-surgical treatment for displaced fractures of the proximal humerus involving the surgical neck in adults. . Methods. A cost utility analysis from the NHS perspective was performed. Differences between surgical and non-surgical treatment groups in costs and quality adjusted life years (QALYs) at two years were used to derive an estimate of the cost effectiveness of surgery using regression methods. . Results. Patients randomised to receive surgical intervention accumulated mean greater costs and marginally lower QALYs than patients randomised to non-surgery. The surgical intervention cost a mean of £1758 more per patient (95% confidence intervals (CI) £1126 to £2389). Total QALYs for the surgical group were smaller than those for non-surgery -0.0101 (95% CI -0.13 to 0.11). The probability of surgery being cost effective was less than 10% given the current NICE willingness to pay at a threshold of £20 000 for an additional QALY. The results were robust to sensitivity analyses. Discussion. The results suggest that current surgical treatment is not cost effective for the majority of displaced fractures of the proximal humerus involving the surgical neck in the United Kingdom’s NHS. Take home message: The results of this trial do not support the trend of increased surgical treatment for patients with displaced fractures of the proximal humerus involving the surgical neck within the United Kingdom NHS.

Purpose and background

To explore the cost-utility of implementing stratified care for low back pain (LBP) in general practice, compared with usual care, within patient risk subgroups (low, medium and high risk of persistent disabling pain determined by the STarT Back tool).

The February 2015 Spine Roundup³⁶⁰ looks at: Paracetamol use for lower back pain; En-bloc resection of vertebra reported for the first time; Spinopelvic disassociation under the spotlight; Hope for back pain; Disc replacement and ACDF equivalent in randomised study; Interspinous process devices ineffective

The aim of this study was to perform a cost–utility analysis of total hip (THR) and knee replacement (TKR). Arthritis is a disabling condition that leads to long-term deterioration in quality of life. Total joint replacement, despite being one of the greatest advances in medicine of the modern era, has recently come under scrutiny. The National Health Service (NHS) has competing demands, and resource allocation is challenging in times of economic restraint. Patients who underwent THR (n = 348) or TKR (n = 323) between January and July 2010 in one Scottish region were entered into a prospective arthroplasty database. A health–utility score was derived from the EuroQol (EQ-5D) score pre-operatively and at one year, and was combined with individual life expectancy to derive the quality-adjusted life years (QALYs) gained. Two-way analysis of variance was used to compare QALYs gained between procedures, while controlling for baseline differences. The number of QALYs gained was higher after THR than after TKR (6.5 vs 4.0 years, p < 0.001). The cost per QALY for THR was £1372 compared with £2101 for TKR. The predictors of an increase in QALYs gained were poorer health before surgery (p < 0.001) and younger age (p < 0.001). General health (EQ-5D VAS) showed greater improvement after THR than after TKR (p < 0.001). This study provides up-to-date cost-effectiveness data for total joint replacement. THR and TKR are extremely effective both clinically and in terms of cost effectiveness, with costs that compare favourably to those of other medical interventions.

To determine the cost-effectiveness of Lumbar Total Disc Replacement (LTDR) with circumferential spinal fusion surgery. Cost utility analysis. We prospectively reviewed a cohort of 32 consecutive patients who underwent LTDR between 2004 and 2008 with a mean follow-up for 3.75 years. Identical data was compared to a similar group of patients (n=37) who underwent fusion in our institution. Oswestry Disability Index, visual analogue scale, quality of life (SF-36) and NHS resource use. Cost-effectiveness was measured by the incremental cost per quality-adjusted life year (QALY) gained. QALY gains were estimated from SF-36 data using standard algorithms. There was no significant intergroup difference in the ODI, VAS and SF-36 pre and post-op. Both treatments produced statistically significant and equivalent improvements in mean health state utility at the 24-month follow-up (0.078 for LTDR, 0.087 for fusion). Costs were significantly lower with LTDR than with fusion due to a shorter mean procedure time (193.6 vs 377.4 minutes) and shorter length of stay (5.8 vs 7 days). The mean cost difference was £2,878 per patient. At 2 years, the cost per QALY gain of the lower-cost option (LTDR) was £48,892 although the cost effectiveness ratio would fall to below £30,000 if it is assumed that the patient benefits of LTDR last for at least 4 years. Both treatments led to significant improvements in patient outcomes which were sustained for at least 24 months. Costs were lower with LTDR which is effective and a more cost-effective alternative

Background: Alternative treatments in displaced fractures of the femoral neck include reduction and internal fixation, and arthroplasty. A variety of treatments are continuously introduced to the health care market and that makes prioritising, based on the severity of the disease, the effectiveness, and the cost effectiveness of the treatment, necessary. The aim of this study was to compare the estimated effect and costs of internal fixation and hemiarthroplasty after a displaced femoral neck fracture.

Methods: 222 patients, 165 (74%) women, mean age 83 years, were randomized to internal fixation (n = 112) and hemiarthroplasty (n = 110). Mainly due to cognitive failure or death, 56 patients failed to complete the EQ-5D questionnaire at any follow up; hence, 166 patients were included in the analysis. There were no differences in the demographic variables at inclusion. Patients underwent either a Charnley-Hastings bipolar cemented hemiarthroplasty or closed reduction and internal fixation with two parallel cannulated screws (Olmed). The health effect was estimated by the generic measure quality adjusted life-years (QALYs). The QALYs were estimated based on the patients’ perception of quality of life (QoL) assessed by Eq-5d, which was measured after 4, 12 and 24 months.

Results: Over the two year period the expected QALYs for patient with hemiarthroplasty and internal fixation were estimated to be 1.31 and 1.11, respectively. Thus, the incremental health effect, the difference in QALYs for hemiarthroplasty versus internal fixation, was 0.20 QALYs gained. Hospital costs over two years were € 30 726 in the internal fixation group and € 27 618 in the hemiarthroplasty group, an incremental cost of – € 3 108 in favor of hemiarthroplasty. Total costs, including societal costs, were € 62 815 in the internal fixation group, compared to € 48 227 in the hemiarthroplasty group, an incremental cost of – € 14 588 in favor of hemiarthroplasty. By dividing the incremental cost by the incremental effect, we found the incremental cost effectiveness ratio (ICER) to be – € 15 540 for all hospital costs and – € 72 940 for total costs. Sensitivity analysis based on the bootstrap method, indicate that the ICER is significantly negative, indicating both a significantly lower incremental costs and significantly higher QALYs for hemiarthroplasty versus internal fixation. Conclusion: Primary treatment with hemiarthroplasty generates more QALYs and is less costly compared to internal fixation. Hemiarthroplasty was thus the cost effective treatment alternative.

We randomly allocated 60 consecutive patients with fractures of the waist of the scaphoid to percutaneous fixation with a cannulated Acutrak screw or immobilisation in a cast. The range of movement, the grip and pinch strength, the modified Green/O’Brien functional score, return to work and sports, and radiological evidence of union were evaluated at each follow-up visit. Patients were followed sequentially for one year.

Those undergoing percutaneous screw fixation showed a quicker time to union (9.2 weeks vs 13.9 weeks, p < 0.001) than those treated with a cast. There was a trend towards a higher rate of nonunion in the non-operative group, although this was not statistically significant. Patients treated by operation had a more rapid return of function and to sport and full work compared with those managed conservatively. There was a very low complication rate.

We recommend that all active patients should be offered percutaneous stabilisation for fractures of the waist of the scaphoid.
