Alexandre.laedermann: Type 1: the most frequent, corresponding to the direct insertion of the posterior labrum in the cartilage surface, without a gap. It represents 60% of shoulders. In type 2 there is no direct contact between cartilage surface and the superior segment of the posterior labrum, with a medialized aspect of the segment. This aspect is frequent (40%) and isolated in 20% of cases. It can be associated with medialization of the medial fragment in 15% of cases corresponding to type 3. Type 4: (5%) all...

Type 1: the most frequent, corresponding to the direct insertion of the posterior labrum in the cartilage surface, without a gap. It represents 60% of shoulders. In type 2 there is no direct contact between cartilage surface and the superior segment of the posterior labrum, with a medialized aspect of the segment. This aspect is frequent (40%) and isolated in 20% of cases. It can be associated with medialization of the medial fragment in 15% of cases corresponding to type 3. Type 4: (5%) all labrum is medialized. A: percentage of medialized aspect of the posterior labrum, by segment. B: percentage of each type of insertion. Bottom: the two modalities of fixation of the posterior labrum: left, in continuity with articular surface; right, medialized aspect, with a gap between the labrum and the cartilage.
