The EB109 fits elbows with tennis elbow, golfer's elbow, or muscular overuse from work, sport, or trauma. Orthopaedic clinics, physiotherapy departments, and sports medicine teams apply it where relief is needed at the tendon insertions, the point the support is designed around.
The design concentrates on that one point. A rigid plastic shell provides firm support, and a non-woven fabric pad adds comfort while holding the epicondyle in place. The support consists of a shell and a pad, so a clinician fitting the EB109 places two parts at the elbow to position the support.
The same support serves different histories. A patient whose overuse comes from work, a patient whose overuse comes from sport and a patient whose elbow was injured by trauma are fitted with the same shell and pad. That lets a clinic keep a single model for every case that presents with strain at the tendon insertions, whatever the cause was. Every patient leaves the appointment with the same two parts at the elbow, in the size selected by the measurement.
Sizing starts with one measurement. We take the largest forearm circumference, and the result selects the size from XS, S, M, L, and XL. Size XS covers 20–22 cm, size S covers 23–25 cm, and size XL covers 31–34 cm. A department that treats a mix of patients stocks all five sizes and fits each elbow based on its own measurement, which keeps the fitting routine the same for every patient.
