Aims: The aim of the study was to investigate the cap-suloligamentous structures of the shoulder joint and their association with rotator cuff tendons.

Methods: Twenty seven alcohol-formalin-glycerol þxed right shoulder joints (age range 65 Ð 78 years) were investigated. The Ligg. coracohumerale, coracoglenoidale, glenohumeralia, semicirculare humeri and gleno-capsulare were dissected in þne detail. To visualise the rotator interval, the Processus coracoideus was cut at its base and moved together with the Ligg. coracohumerale and coracoglenoidale posteriorly. The analysis of the ligamentous structures and their relations with the rotator cuff tendons was performed.

Results: The Lig. coracohumerale originated from Processus coracoideus and Lig. coracoglenoidale. It inserted into the Lig.semicirculare humeri Ð a capsular ligament spread between Tubercula minus et majus. Lig. glenocapsulare originated posterior to the Tuberculum supragle-noidale and inserted into the Lig. semicirculare humeri. The Mm. supra- and infraspinatus inserted into the Lig. semicirculare humeri. The anterior capsule was strengthened in addition to the three Ligg. glenohumeralia with a Lig. glenohumerale spirale. It originated from the Tuberculum infraglenoidale, coursed craniolaterally and inserted together with the M. subscapularis tendon at the Tuberculum minus.

Conclusions: The shoulder joint capsule is strengthened with the Ligg. coracohumerale, coracoglenoidale, glenohumeralia superior, medium, inferior et spirale and Ligg. semicirculare humeri et glenocapsulare. The close relation of the ligamentous structures with the tendons of the rotator cuff brings a new insight into the different glenohumeral pathologies.
