Résumé
Superior labrum anterior to posterior (SLAP) lesion is a tear of the superior labrum, which starts posteriorly and extends anteriorly to include the anchor of the biceps tendon to the superior labrum. Symptoms of SLAP tear may include pain or instability. Recently, with the development of arthroscopy, the diagnosis and treatment of SLAP lesion have been made a lot. However, the diagnosis of clinically relevant SLAP tears remains challenging because of the lack of specific examination findings and the frequency of concomitant shoulder lesion. And there is still controversy regarding the treatment. Accordingly, proper treatment is important through accurate evaluation of whether or not it is a clinically important SLAP lesion.

Role of the superior labrum-biceps complex for the glenohumeral stability is still unclear. Nevertheless, isolated superior labrum anterior to posterior (SLAP) lesion can cause glenohumeral instability in young patient (especially in throwing athletes) and SLAP lesion are a well-known pathology entity in acute or chronic glenohumeral dislocation. Ten types of SLAP lesion have been classified by arthroscopic examination, among them type II and type IV through X SLAP can disturb glenohumeral stability by disrupting the anchoring of biceps. Arthroscopic repair of labrum is the most preferred method for SLAP lesion with glenohumeral instability in younger patient. Surgical treatment, if necessary, should address all aspects of the labral anatomy so that all the roles of the labrum in shoulder stability must be restored. In terms of restoration for glenohumeral instability, the good clinical results have been reported after arthroscopic repair of a SLAP with Bankart lesion. But, it is still a work in progress for long term clinical follow-up and understanding about relationship between SLAP lesion and glenohumeral instability.
