HUMERO RADIAL PLICA CAUSING LATERAL ELBOW PAIN, AN ANALYSIS OF 117 ELBOW ARTHROSCOPIES.

Abstract

The aim of the study is to assess the humero radial plica which could be a factor in causing lateral elbow pain. The cause of lateral elbow pain has been an enigma for the orthopaedic surgeons over the years. The synovial fold of the humeroradial joint has been well documented and considered as a meniscus between the articulation. They can also present as symptoms suggesting intra articular loose bodies causing pain in these patients. Our study included 117 consecutive elbow arthroscopies performed by two surgeons for a period of 18 months. All patients were initially treated non-operatively as a ‘tennis elbow’ before undergoing arthroscopy. Conservative treatment included rest, activity modification, physiotherapy including ultrasound bracing, nsaids and local corticosteroid injection. All patients were assessed using the Mayo clinic performance index for elbows both pre and post operatively. Radial head plica was found in 21(18%) out of 117 elbow arthroscopies and was resected using a soft tissue resector. There were 16 (76%) men and 5(24%) women in this affected group and all of whom were young and active with a mean age 38 years. Of the 21 patients 16(76%) had a post operative score of 90 or more (excellent) and 5(24%) had a score 75–89(good). This study addresses the fact that cause of lateral elbow pain can be due to various pathologies in the elbow and in the cases of ‘resistant tennis elbows’ we recommend that the existence of a radial head synovial plica should be considered and if present treatment should be directed at this. Our study demonstrates that by resecting the synovial plical fold, pain will be relieved and these patients regained elbow function. Since this was noted in the young active age group this could reduce the morbidity and the time for rehabilitation required especially for those involved in active sports.
