Objective: To study the role of Modified Nirschl Procedure in treatment of resistant lateral epicondylitis.
Background: 5-10 % of cases of lateral epicodylitis are resistant to conservative treatment and need surgical intervention. The purpose of this study was to evaluate the clinical outcomes of Modified Nirschl techniques for treatment of tennis elbow.
Methods: A Prospective case series study was designed between February 2019 and January 2020 included 20 patients from outpatient clinic of Benha university hospital suffering from resistant lateral epicondylitis. Detailed medical history, clinical examination and PRTEE score applied to all patients pre and post-operatively.
Results:  There were 8 female and 12 male patients in the study. The mean duration of symptoms before surgery was 14.3 months. The average duration of follow up was 28 months. We found that the Modified Nirschl Procedure has encouraging results in management of lateral epicondylitis in (95%) of cases with a mean of 4 weeks period to return to normal activities and 15.3 weeks to resume heavy activities without pain. The total PRTEE score improved from a mean of 67 points to a mean of 6 points postoperatively.
Conclusion: The Modified Nirschl Procedure shares nearly equal results with other procedures, although the patients return to their activities later than the other methods. Also this method has an advantage of good visualization of the whole degenerated tissues ensuring perfect debridement. Therefore, we suggest this option after failed conservative management of lateral epicondylitis.
