The cleft sign may be an independent factor of magnetic resonance imaging findings associated with a delayed return-to-play time in athletes with groin pain.

Purpose: To investigate the prevalence of magnetic resonance imaging (MRI) findings and define prognostic factors of the return-to-play time in young athletes with groin pain.

Methods: A total of 1091 consecutive athletes were retrospectively screened; 651 athletes, aged 16-40 years, with pain in the groin regions were assessed using MRI. Of these athletes, 356 were included for analysing the time to return-to-play.

Iliopsoas Disorder in Athletes with Groin Pain: Prevalence in 638 Consecutive Patients Assessed with MRI and Clinical Results in 134 Patients with Signal Intensity Changes in the Iliopsoas.

Background: Although iliopsoas disorder is one of the most frequent causes of groin pain in athletes, little is known about its prevalence and clinical impact.

Methods: We retrospectively reviewed the cases of 638 consecutive athletes who had groin pain. Each athlete was assessed with magnetic resonance imaging (MRI).
