Background:
Lateral epicondylitis (LE) or tennis elbow is the most common elbow painful condition. It affects around 1 to 3% of adults. There are various possibilities of treatment described in the literature, without evidence to support a gold standard management protocol. Therefore, the objective of this study is to evaluate how the Brazilian orthopedist diagnoses and treats lateral epicondylitis, to compare these results with the available evidence.
Methods:
This is an observational, analytical, cross-sectional study. A questionnaire has been prepared for information to the participants and with eight specific questions (2 on diagnosis and 6 on treatment). These had been answered voluntarily by participants at 3 major congresses of orthopedists in Brazil in 2018. The results were analyzed in accordance with the overall number of responses, and were evaluated among groups according to subspecialty.
Results:
We obtained a total of 501 questionnaires. Of these, 33 were excluded. The mean age was 38.67 years. The majority of respondents (91%) were male. We obtained 26.7% from specialists in hand surgery (Hand group), 36.5% from subspecialists in shoulder and elbow (Shoulder and Elbow group), and 36.8% were from generalists in orthopedics or from other subspecialties (General Orthopedists group). For diagnosis, 24.4% have not initially requested any imaging method. The most requested exam was ultrasonography (54.9%). The most prominent indication for initial treatment was physical therapy. For refractory cases, 78.3% of the respondents prefer doing a local infiltration. The most commonly used substance for local infiltrations is corticosteroids (89.6%). With respect to the surgical treatment option, 75.8% of those who recommend it prefer open techniques and 24.2% arthroscopic treatment. Of the total respondents, 12.8% do not recommend surgical treatment for LE.
Conclusion:
Most orthopedists begin the treatment of lateral epicondylitis with the use of non-steroidal anti-inflammatory drugs, physical therapy, and an indication of rest, but there is great variability between their recommendations. The use of corticosteroids for infiltration remains the main choice among Brazilian orthopedists, although evidence shows a better effect in the short term and a worse effect in the medium and long term, compared to other treatments.
