Pain, Elbow
Conditions
Brief summary
Background: Lateral epicondylitis, or tennis elbow, is a common musculoskeletal disorder that causes pain and functional limitation. Although different nonsurgical conservative therapies such as bracing, physical therapy, nonsteroidal anti-inflammatory drugs, and corticosteroid injections in addition to surgical approaches have been used, yet there is no standard treatment for lateral epicondylitis. Objectives: The primary objective of this study is to assess the effectiveness of nerve stimulator guided radial nerve block for treatment of lateral epicondylitis. The primary outcome measure is pain measured through the Visual Analogue Scale (VAS) at 1 and 2 weeks. Methods: This is a prospective randomized, double blind clinical trial. Patients will be randomly allocated into two groups. Group I will receive radial nerve block guided by a nerve stimulator. Group II patients will receive placebo through radial nerve block. Patients will be followed up for 2 weeks.
Detailed description
Lateral epicondylitis, or tennis elbow, is a common musculoskeletal disorder that causes pain and functional limitation. It is a major arm disorder which occurs commonly in adults between 30 and 50 years, with an estimated prevalence of 1% to 3% in the general population. Lateral epicondylitis results from the overuse of the extensor muscles, causing inflammation or irritation of the tendon insertion. It is common in workers whose job requires manual and repetitive work . Although different nonsurgical conservative therapies such as bracing, physical therapy, nonsteroidal anti-inflammatory drugs, and corticosteroid injections in addition to surgical approaches have been used, yet there is no standard treatment for lateral epicondylitis. To our knowledge, there are no studies that used nerve-stimulator-guided radial nerve block for the treatment of lateral epicondylitis.
Interventions
OTHERRadial nerve block
A nerve stimulator will be used to localize the radial nerve. Then radial block will be performed. At this point 3-5 ml of the anesthetic mixture is injected. Each 10 ml of the anesthetic mixture contained: 3ml lidocaine 2%, 3ml lidocaine 2% with epinephrine, 1:2000,000, 3ml bupivicaine 0.5% and 1ml clonidine 150 µg/ml.
OTHERPlacebo
A nerve stimulator will be used to localize the radial nerve. Then radial block will be performed containing normal saline
