# Superior labrum anterior to posterior lesions: Part 2 – Classification with arthroscopic correlation

## TL;DR

This paper provides a detailed classification of SLAP lesions in the shoulder joint using imaging and arthroscopy to guide treatment.

## Contribution

The paper expands and illustrates the classification of SLAP lesions with MRI and arthroscopic images for better diagnosis and management.

## Key findings

- There are 10 distinct types of SLAP lesions identified through arthroscopic and imaging correlation.
- Combining MRI and arthroscopy improves understanding of labral pathology for accurate diagnosis.
- The classification system aids orthopaedic surgeons in selecting appropriate treatment strategies.

## Abstract

The glenoid labrum deepens the glenoid fossa and allows for the attachment of the long head of the biceps tendon and glenohumeral ligaments, contributing to the stability of the glenohumeral joint. The superior labrum is a common site of labral injury. The acronym SLAP (superior labrum anterior to posterior or anteroposterior) lesion was introduced by Snyder and colleagues in 1990 to describe superior labral tears based on arthroscopic evaluation. This original classification has since been expanded, and there are currently 10 types of SLAP lesions. The article will describe and illustrate the 10 types of SLAP lesions by means of colour illustrations, MRI images and correlative arthroscopy images. A practical approach to the assessment of SLAP lesions will be recommended.

The illustrated review functions as a crucial radiological guide for both radiologists and orthopaedic surgeons. The combination of illustrations, MR and correlative arthroscopic images enhances the comprehensive understanding of labral pathology. The value of the review lies in the presentation of imaging findings and classification, coupled with findings on arthroscopy. This understanding is vital in guiding orthopaedic management for patients, ensuring appropriate treatment strategies.
