[Introduction]
Lateral epicondylitis(LE), also called as tennis elbow, is known to be one of the most common cause of elbow pain. It represents a degenerative process involving origin of common extensor tendon(CET) at lateral elbow. Local steroid injection is known to be effective treatment method of LE. It is known to be more difficult to treat LE pain when there is additional injury of radial collateral ligament(RCL). This study aimed to compare the treatment effect of local steroid injection for CET injury with the effect for RCL injury in lateral epicondylitis.
[Methods]
Ten patients with LE who were treated at the outpatient department of Kwangju christian hospital rehabilitation medicine from 2019 to 2020 were examined(Table 1). The patients were divided into 2 groups : LE with CET and RCL injury (group 1; fig 1) and LE with CET injury only (group2; fig 2) by sonographic findings. CET injury was defined as local hypoechoicity with loss of fibrillar pattern, and RCL injury defined as local hypoechoicity on ultrasound. Local steroid injection was done in all patients. Additional injection was done only if patient complained severe pain( >VAS 6). We estimated therapeutic effects by the number of steroid injection in two groups.
[Results]
There was no significant statistical differences in pain(VAS) between group 1 and group 2(table 1). The number of local steroid injection was different between 2 groups. Group 2 got more injections compared with group 1(table 2).
[Conclusion]
In this study, we find that it is more difficult to treat LE with CET & RCL injury group (group1) compared with LE with CET injury only group(group2) by local steroid injections. So it is important to evaluate RCL injury when we examine the patients with LE by ultrasound. If there is any additional RCL abnormality, we should explain the patients with LE the difficulties of treatment and need for long-term management. Also we can maintain rapport with patients with LE with RCL injury by steady and comprehensive care.
