Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Particpants selcted to the active arm will be provided with a fascial hydrodissection technique using 5% glucose , lignocaine 1% (2 mls) and Dexamethasone 8 mgs. Approximately 10 mls will be used for the hydrodissection. The injections are performed ultrasound guided. Injections are usually performed on a single occasion.
Intervention code [1] 322971 0
Treatment: Drugs
Comparator / control treatment
The usual treartment for cluneal nerve impingement is an injection of a mixture of lignocaine 1% and Dexamethaosne 8 mgs, around the nerve. The injection will be performed using ultrasound guidance injection is anticapted to be used on a single occasion.

Active

Efficacy
Statistical methods / analysis
A pilot study was conducted and a power study undertaken to determine minimum numbers to provide a statistical difference between the groups. There were 25 cases in the sample. 13 cases with superior cluneal nerve pain (exposed) and 12 cases with no superior cluneal pain (unexposed). Therefore the ratio of unexposed : exposed=12/13=0.923.

Buttock pain was reported in 12 cases. Therefore the % outcome in the unexposed group is 13/25=52%.

Full study Statistical Method: Fleiss with continuity correction

Assuming the ratio of unexposed : exposed=50/50=1.

In order to achieve 95% two-sided confidence level with 80% power, we need a sample of 38 cases.

Statitsical analysis: if the distribution appears normally distributed then an Independent group T test will be applied. If the data is not normally distributed then either Mann Whitney or Welch's t-test will be applied

Summary
Brief summary
We aim to see if there is a difference between 2 injection types to treat a nerve impingement that can cause low back and buttock pain. We wish to see if a newer technique is more efficacious and has a longer lasting effect than the usual technique
