[Purpose] This study evaluated the effect of age, sex, and entrapment localization on recovery time in patients treated conservatively for ulnar neuropathy at the elbow. [Subjects] Thirty-five patients (16 women and 15 men) who were diagnosed with ulnar neuropathy at the elbow using short segment conduction studies were evaluated retrospectively. [Methods] Definition of recovey was made based on patient satisfaction. The absence of symptoms was considered as the marker of recovery. Patients who recovered within 0-4 weeks were in Group 1, and patients who recovered within 4 weeks to 6 months were in Group 2. The differences between Group 1 and Group 2 in terms of age, sex and entrapment localization were investigated. [Results] Entrapment was most frequent in the retroepicondylar groove (54.3%). No significant difference was found in terms of age and entrapment localizations between Groups 1 and 2. There was a statistically significant difference between the groups for the male sex. [Conclusion] In ulnar neuropathy at the elbow, age and entrapment localization do not affect recovery time. However, male sex appears to be associated with longer recovery time.
