Lateral Epicondylalgia and Thoracic Kyphosis: A Study on Young Athletes

The etiology of lateral epicondylalgia (LE) remains unclear, although it has been linked to various factors. Recent theories suggest a potential connection between LE and impairments in the kinetic chain. In our study, we aimed to investigate the association between another factor influencing kinetic chain impairment, specifically an increased angle of thoracic kyphosis, and the presence of initial signs of LE in young athletes.

This study employed an observational, case-control design.

The participants underwent examination during a routine preventive checkup conducted by a sports physician at Novi Sad Healthcare Center, Sports Medicine Center.

One hundred young athletes aged 10 to 15 years were included in the study. Half of the participants reported pain in the lateral aspect of the elbow during maximal hand grip, while the remaining athletes served as controls and did not experience any pain.

Thoracic kyphosis inclination angles were measured using a digital inclinometer.

Pain was assessed using the pressure pain threshold at a specific point associated with lateral epicondylalgia, measured by a digital algometer.

Participants exhibiting initial signs of LE displayed significantly different angles of anteroposterior curvatures of the spine compared with the control group. Moreover, the angle of thoracic kyphosis was significantly associated with pain in the lateral aspect of the elbow.

Our findings confirm an association between initial signs of lateral epicondylalgia and the grade of thoracic kyphosis in young athletes.
