the variable morphology of Suprascapular nerve and vessels at Suprascapular Notch a proposal for classification and its potential clinical implications
Knee Surgery Sports Traumatology Arthroscopy, 2015Co-Authors: Michal Polguj, Marcin Sibinski, Agata Majos, Andrzej Grzegorzewski, J J Rozniecki, Miroslaw TopolAbstract:Purpose The most common place for Suprascapular nerve entrapment is the Suprascapular Notch. The aim of the study was to determine the morphological variation of the location of the Suprascapular nerve, artery and vein, and measure the reduction in size of the Suprascapular opening in each type of the passage.

a proposal for classification of the superior transverse scapular ligament variable morphology and its potential influence on Suprascapular nerve entrapment
Journal of Shoulder and Elbow Surgery, 2013Co-Authors: Michal Polguj, Kazimierz Jedrzejewski, Agata Majos, Michal Podgorski, Miroslaw TopolAbstract:Background The Suprascapular region is the most common site of Suprascapular nerve entrapment. The aim of the present study was to determine the morphologic variation of the superior transverse scapular ligament (STSL) and measure the reduction in size of the Suprascapular opening. Other structures that might be potentially significant during open and arthroscopic procedures in this region are also described. Materials and methods The study used 86 randomized formalin-fixed human cadaveric shoulders. After dissection of the Suprascapular region, the following measurements were defined and collected for every STSL: length, proximal width, distal width, and thickness at the proximal and distal ends. Measurements were also taken of the area of the Suprascapular opening (aSSO) and the middle width of the Suprascapular opening (mwSSO). Results Three types of STSL may be distinguished: a fan-shaped type (54.6%), a band-shaped type (41.9%), and a bifid type (3.5%). Statistically significant differences between the specimens with fan-shaped and band-shaped types of STSL were observed in aSSO and mwSSO of the Suprascapular opening. Anterior coracoscapular ligaments (ACSL) were present in 44 of 86 shoulders. The aSSO and mwSSO were smaller in specimens with an ACSL than in those without; however, this difference was only significant in the band-shaped type of STSL. Conclusion Knowledge of the morphologic variations of STSL presented in this study is important for better understanding the possible anatomic conditions that can promote Suprascapular nerve entrapment and should be taken into particular consideration during surgical and arthroscopic procedures around the Suprascapular Notch.

coexistence of the Suprascapular Notch and the Suprascapular foramen a rare anatomical variation and a new hypothesis on its formation based on anatomical and radiological studies
Anatomical Science International, 2013Co-Authors: Michal Polguj, Kazimierz Jedrzejewski, Agata Majos, Miroslaw TopolAbstract:The Suprascapular Notch is the most common site of Suprascapular nerve entrapment, which can manifest in disability and pain of the upper limb. Here, we present three cases of a very rare anatomical variation in the Suprascapular region: the coexistence of the Suprascapular Notch and the Suprascapular foramen. The variation was found during radiological and anatomical investigations. The Suprascapular foramen was situated inferior to the Suprascapular Notch. A bony bridge lay between them, likely created by an ossified anterior coracoscapular ligament (ACSL). This anatomical variation probably increased the risk of Suprascapular nerve entrapment by nerve irritation of the bony margins during passsage through the foramen and by a lack of the elasticity that the ACSL normally demonstrates. Also, a bony bridge passing through the middle part of the Suprascapular Notch reduces the space available for nerve passage (bony bridge decreases the space by about 36.5–38.6 %). One patient who underwent the radiological study had typical symptoms of Suprascapular nerve entrapment. Based on his medical history and the presence of this rare variation of the Suprascapular Notch at the Suprascapular region we suspect this neuropathy.

variations in bifid superior transverse scapular ligament as a possible factor of Suprascapular entrapment an anatomical study
International Orthopaedics, 2012Co-Authors: Michal Polguj, Kazimierz Jedrzejewski, Agata Majos, Miroslaw TopolAbstract:Purpose The Suprascapular region is the most common place for Suprascapular nerve entrapment. The purpose of this research was to investigate the influence of the superior transverse scapular ligament (STSL) on the reduced space for Suprascapular nerve passage at the Suprascapular Notch. Additionally, we precisely described other structures that seem important during arthroscopic and open procedures in this region.

Research Article Morphological and Radiological Study of Ossified Superior Transverse Scapular Ligament as Potential Risk Factor of Suprascapular Nerve Entrapment

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The Suprascapular Notch is covered superiorly by the superior transverse scapular ligament. This region is the most common place of Suprascapular nerve entrapment formation. The study was performed on 812 specimens: 86 dry scapulae, 104 formalin-fixed cadaveric shoulders, and 622 computer topography scans of scapulae. In the cases with completely ossified superior transverse scapular ligament, the following measurements were performed: proximal and distal width of the bony bridge, middle transverse and vertical diameter of the Suprascapular foramen, and area of the Suprascapular foramen. An ossified superior transverse scapular ligament was observed more often in men and in the right scapula. The mean age of the subjects with a completely ossified superior transverse scapular ligament was found to be similar than in those without ossification. The ossified band-shaped type of superior transverse scapular ligament was more common than the fan-shaped type and reduced the space below the ligamen

morphological and radiological study of ossified superior transverse scapular ligament as potential risk factor of Suprascapular nerve entrapment

The mean age of the subjects with a completely ossified superior transverse scapular ligament was found to be similar than in those without ossification. The ossified band-shaped type of superior transverse scapular ligament was more common than the fan-shaped type and reduced the space below the ligament to a significantly greater degree. The ossified band-shaped type should be taken into consideration as a potential risk factor in the formation of Suprascapular nerve entrapment. It could explain the comparable frequency of neuropathy in various populations throughout the world despite the significant differences between them in occurrence of ossified superior transverse scapular ligament.

Suprascapular Notch Asymmetry: A Study on 311 Patients
Hindawi Limited, 2014Co-Authors: Michał Polguj, Marcin Sibinski, Andrzej Grzegorzewski, Ludomir Stefańczyk, Piotr Grzelak, Mirosław TopolAbstract:The most important risk factor of Suprascapular nerve entrapment is probably the shape of the Suprascapular Notch (SSN). The aim of the study was to perform a radiological study of the symmetry of SSN. Included in the study were 311 patients (137 women and 174 men) who underwent standard computed tomography investigation of the chest. A total of 622 computed tomography scans of scapulae were retrospectively analyzed to classify Suprascapular Notches into five types. Suprascapular Notch was recognized as a symmetrical feature in 53.45% of the patients. Symmetry was more frequently seen in females (54.0% versus 52.9%), but not to any significant degree (P=0.8413). Type III was the most commonly noted symmetrical feature (66.9%) and type II was less common (0.6%). Type III was the most symmetrical type of Suprascapular Notch, occurring significantly more often as a symmetrical feature in comparison with type I (P
