Dr Alashkham and his colleagues have reported that the glenoid labrum is fibrocartilaginous, being more fibrous in its periphery, and is vascularised, with the anterosuperior aspect having a rich blood supply. Free sensory nerve fibres were also present; no encapsulated mechanoreceptors were observed. The presence of sensory nerve fibres in the glenoid labrum could explain why tears induce pain. It is postulated that these sensory fibres could play a role in glenohumeral joint proprioception. The paper has been published in the Journal of Orthopaedic Surgery and it is free to download.
