Circumflex arterial sulcus of the scapula (sulcus arteriae circumflexae scapulae): its anatomy and clinical relevance.

Introduction: The circumflex scapular artery (CSA) has been described in detail in the literature, but the groove, i.e., the circumflex sulcus (CFS), formed by the artery on the lateral pillar of the scapula has been completely neglected.

The coracoglenoid notch: anatomy and clinical significance.

Introduction: The superior surface of the anatomical neck is presented in the classification of scapular fractures as a 2-cm-long structure, which does not correspond to reality. This issue has not yet been adequately addressed in the literature. The aim of the study was to assess the variability of a notch between the upper rim of the glenoid and the coracoid base, the so-called coracoglenoid notch (CGN), and its clinical significance.

Fractures of the coracoid process - pathoanatomy and classification: based on thirty nine cases with three dimensional computerised tomography reconstructions.

Purpose: Until now, classifications of coracoid fractures have been based on plain radiographs, without use of 3D CT reconstructions. Therefore, the aim of the present study has been to describe the pathoanatomy of these fractures and their associated injuries to the shoulder girdle, on the basis of 3D CT reconstructions.

Methods: The cohort comprised 39 patients, who each sustained a coracoid fracture investigated with 3D CT reconstructions.
