[Q]: Question: Is sleep disturbance after fracture related to emotional well-being rather than functional result?
Answer: At 12-month follow-up, poor sleep was independently associated with poor emotional status but not associated with poor functional status. The mental health status of patients with sleep difficulty in the latter stages of fracture healing should be carefully assessed to provide the highest level of care. The results of this study should allow orthopaedic trauma surgeons to counsel patients regarding expectations of difficulty sleeping after acute fractures.
