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. Data for patients’ use of post-operative healthcare resources
and time taken to return to work were collected and costed using
publicly available sources. Health-related quality of life, assessed
using the Health Utilities Index Mark-3 (HUI-3), was used to derive
quality-adjusted life years (QALYs). Costs and QALYs were compared
between LIPUS and control (a placebo device) from a payer and societal
perspective using non-parametric bootstrapping. All costs are reported
in 2015 Canadian dollars unless otherwise stated.Aims

In Canada, Dupuytren's contracture is managed
with partial fasciectomy or percutaneous needle aponeurotomy (PNA).
Injectable collagenase will soon be available. The optimal management
of Dupuytren’s contracture is controversial and trade-offs exist
between the different methods. Using a cost-utility analysis approach,
our aim was to identify the most cost-effective form of treatment
for managing Dupuytren’s contracture it and the threshold at which
collagenase is cost-effective. We developed an expected-value decision
analysis model for Dupuytren’s contracture affecting a single finger,
comparing the cost-effectiveness of fasciectomy, aponeurotomy and collagenase
from a societal perspective. Cost-effectiveness, one-way sensitivity
and variability analyses were performed using standard thresholds
for cost effective treatment ($50 000 to $100 000/QALY gained).
Percutaneous needle aponeurotomy was the preferred strategy for
managing contractures affecting a single finger. The cost-effectiveness
of primary aponeurotomy improved when repeated to treat recurrence.
Fasciectomy was not cost-effective. Collagenase was cost-effective
relative to and preferred over aponeurotomy at $875 and $470 per
course of treatment, respectively. In summary, our model supports the trend towards non-surgical
interventions for managing Dupuytren’s contracture affecting a single
finger. Injectable collagenase will only be feasible in our publicly
funded healthcare system if it costs significantly less than current
United States pricing. Cite this article:
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 We recommend that all active patients should be offered percutaneous stabilisation for fractures of the waist of the scaphoid.
