An injection of botox or botulinum injection, provides relief from tennis elbow. A single dose of it can provide relief but needs to be injected properly to avoid potential paralysis. A randomised controlled trial of 48 patients was conducted to introduce an easy and effective method to inject the drug.
Instead of a fixed injection site physicians determined the injection site based on each patient’s forearm length. The result found that pain at rest and pain during maximum pinch were significantly reduced in patients with lateral epicondylitis [tennis elbow] after botulinum toxin was injected at the site based on precise anatomic measurement of each patient’s forearm length. However, this method caused a decline in maximum strength and resulted in extensor lag.
