Study information

Scientific title

A double-blind multi-centre randomised controlled trial to investigate the effectiveness of methylprednisolone injections in the treatment of Morton's neuroma



Study hypothesis

The trial is designed primarily to address the question: is local injection of steroid (methylprednisolone) an effective treatment for Morton's neuroma? Thus we seek to test the following null hypothesis: that steroid injections are as effective as anaesthetic injections for the pain and the effects of pain associated with Morton's neuroma.

Ethics approval

Lothian Research Ethics Committee (Orthopaedic surgery/surgery Research ethics sub-committee), 23/11/2000, ref: LREC/2000/5/31

Study design

Incremental cost-effectiveness analysis and single-blind pragmatic randomised controlled trial

Primary study design


Secondary study design

Randomised controlled trial

Patient information sheet


Morton's neuroma


Participants will be allocated to receive steroid and anaesthetic (injection of 1 ml methylprednisolone and 1 ml 2% lignocaine) or just anaesthetic (2 ml of 1% lignocaine). All ultrasound examinations and injections will be performed by the same musculoskeletal radiologist using an ATL HDI 5000 (Seattle, Washington) with a 7-12MHz transducer. Neuroma will be injected by a plantar approach. Patients will receive only a single injection and patints will be reviewed clinically after 3 months.

Primary outcome measures

1. Patient completed booklet of outcome measures, comprehensive yet brief, will cover the following domains:
1.1. Foot Health Status - the Foot Thermometer, a validated 10 cm visual analogue scale of foot health, will be the primary outcome measure. A validated questionnaire-based measure of foot health status will complement it.
1.2. Functional Disability - the Manchester Foot Pain and Disability Schedule has been validated for use as a measure of disability specifically associated with foot pain
1.3. Pain - the Multidimensional Affect and Pain Survey (MAPS) is a widely validated questionnaire developed from cluster analysis of common descriptors for pain and its effects. It covers three dimensions: pain as a sensory experience; suffering associated with pain; and uniquely, for this type of measurement tool, general well-being in the presence of pain.
1.4. General Health Status - the EuroQol, a single validated index for describing and valuing health states. It consists of five items - mobility, self-care, usual activities, pain or discomfort, and anxiety or depression - and a visual analogue scale of global health status.
2. Need for surgical excision of the digital nerve, based on explicit criteria
3. The size of the neuroma, as determined by ultrasonic scan

All measured at 1 month, 3 months and 12 months.

Secondary outcome measures

Patients will receive essentially the same outcome booklets as above 1, 3 and 12 months after treatment. In the case of non-response to postal questionnaires, the research secretary will send out written reminders to patients after 1 and 2 weeks: the research secretary will also contact patients by telephone at the time of posting the second reminder. Additional clinical information, such as adverse events, will be documented by the trial clinical co-ordinator at the clinical review appointment after four months. This information will be forwarded, by post, directly to the research secretary as part of the usual routine of clinical documentation.
