Plain English summary of protocol
Background and study aims
Cervical brachialgia is a type of pain that tracks from the neck down the arms, and is caused by nerve compression in the neck. There are two types of operation used to treat cervical brachialgia - posterior cervical foraminotomy (PCF), where the operation is done through the back of the neck, and anterior cervical discectomy (ACD), which involves operating through the front of the neck.
This trial aims to determine the clinical effectiveness and cost effectiveness of PCF and ACD for the treatment of cervical brachialgia.
Who can participate?
Adults with a diagnosis of unilateral cervical brachialgia as confirmed by MRI or CT myelogram, who have had symptoms for at least 6 weeks
What does the study involve?
Potential participants will be identified in neurological centres in the UK following referral from their GP. They will be given a patient information sheet and informed consent will be taken if they would like to take part. Participants will then have standard assessments performed, as well as an ASIA assessment. Participants will complete questionnaires, and randomised to receive either PCF or ACD surgery on the day of their operation.
The day after, and 6 weeks after the operation, standard assessments and an ASIA assessment will be performed on participants. On day 1, and weeks 6, 12, 26, 39 and 52 after the operation, participants will complete questionnaires.
25% of participants will also have a voice recording taken to assess if their voice is affected by the operation, before surgery and 6 weeks after surgery.
What are the possible benefits and risks of participating?
Treatment in the trial is the same as standard of care, and so the risks and benefits are the same as if the patient did not take part. The possible benefit is that the surgery may alleviate the participants' symptoms. The possible risk is complications of surgery.
Where is the study run from?
The study is run from the Clinical Trials Research Unit (CTRU) at the University of Leeds (UK). It will take place at Leeds General Infirmary and other neurosurgical centres across the UK
When is the study starting and how long is it expected to run for?
November 2018 to June 2022
Who is funding the study?
National Institute for Health Research (UK)

| Scientific title | FORVAD: clinical and cost-effectiveness of posterior cervical FORaminotomy Versus Anterior cervical Discectomy in the treatment of cervical brachialgia: a multicentre, phase III, randomised controlled trial |
| Study objectives | The aim of the study is to determine the clinical and cost effectiveness of posterior cervical foraminotomy (PCF) compared to anterior cervical discectomy (ACD) in the treatment of patients with cervical brachialgia. |
| Ethics approval(s) | North West - Greater Manchester Central Research Ethics Committee, 19/11/2018, 18/NW/0682 |
| Health condition(s) or problem(s) studied | Cervical brachialgia |
| Intervention | Participants will be randomly allocated to one of two groups. Each group will receive a different operation - one group will receive posterior cervical foraminotomy (PCF), which involves operating through the back of the neck, and the other group will receive anterior cervical discectomy (ACD), which involves operating through the front of the neck. Both operations are standard treatments for cervical brachialgia. Participants will be randomised to either the PCF or ACD group on the day of their surgery. At day 1 post surgery, participants will have routine assessments performed, as well as an ASIA (American Spinal Injury Association) assessment. Participants will also complete a questionnaire pack. Participants will then attend the clinic 6 weeks post surgery for routine clinical assessment as they would as part of standard care, and have another ASIA assessment performed. Participants will then complete a questionnaire pack, and do a voice recording if applicable. On weeks 12, 26, 39 and 52 a questionnaire pack will be sent to participants by post for completion and return by post, participants will be sent email or text reminders if they consented to this on the consent form. 25% of participants will be selected at registration to provide a voice recording. This will be completed before the operation and 6 weeks after the operation. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | Neck pain, assessed using the Neck Disability Index (NDI) at the baseline and 52 weeks post-surgery |
| Secondary outcome measures | To compare PCF and ACD in terms of: 1. Neck and upper limb pain including the shoulder, arm and hand assessed using Numerical Rating Scales, and neuropathic pain (including dysesthetic pain) assessed using the PainDETECT tool over 52 weeks post-surgery 2. Dysphagia (difficulty swallowing) and globus (sensation of a lump in the throat) over 52 weeks post-surgery as assessed by the participant-completed Eating Assessment Tool (EAT-10) and the Glasgow and Edinburgh Throat Score (GETS) questionnaires 3. Hoarse voice over 52 weeks post-surgery, assessed by the participant completed Voice Handicap Index-10 (VHI-10) and at 6 weeks for a sub-set of participants that have a central Grade, Roughness, Breathiness, Asthenia and Strain (GRBAS scale) assessment of their recorded voice 4. Extent and severity of a patient’s spinal cord function, including upper limb nerve root function, using the American Spinal Injury Association (ASIA) score at 1 day and 6 weeks post-surgery 5. Incidence of revision surgery, collected on a case report form (CRF) over 52 weeks post-surgery 6. Incidence of surgical complications, collected on a CRF up to 6 weeks post-surgery 7. Cost-effectiveness, assessed by a health economist over 52 weeks post-surgery |
