“…In the literature, the incidence of complete ossification of STSL was stated to be between 3 to 12.5% [3], where its incidence was 12.5% and 6% in Turkish [28], 7.3% in Germans [8], 7% in polish [3], 8% in Indians [23], and 8% in Uganda [13]. However, lower incidence rates were reported in other studies; 1.36% in Chinese [27], 2.47% in Anatolian population [33], 3% in Egyptian [30], 3% in Kenyan [22] and 3.7%-4% in Americans [4,16]. Meanwhile, the highest incidence rate of the ossified STSL was reported in Brazilians 30.6% [34].…”

“…The exact cause of the diversity and mechanism of STSL ossification was not identified yet, where the incidence of complete STSL ossification seemed to be population specific with genetic and geographic relation in each ethnic group [ 33 ]. Moreover, the difference in STSL ossification might be related to the variation in the classification methods of SSNs used in each study [ 27 ].…”

“…However, the ossification of the band-shaped STSL was found to be three times more frequently than the fan-shaped type [ 7 ]. Clinically, complete ossification of STSL [ 4 , 33 ] and shape of the ossified STSL were considered as predisposing factors for SNES, where the space below the ossified band-shaped STSL showed a significant reduction compared with that in case of the ossified fan-shaped ligament. Thus, the ossified band-shaped STSL was considered as a potential risk factor in SNES [ 7 , 16 ].…”

Understanding the anatomy of suprascapular area helps the clinicians and surgeons in management of any disability at the shoulder region. This work aimed to clear the different morphological and morphometrical types of suprascapular notch (SSN). Unknown 120 dry human scapulae of both sides and 60 formalin-embalmed cadaveric upper limbs (40 males and 20 females) were used in the present study. Three main morphological forms of SSN were reported: J, U, and V-shaped. J-shaped notch showed the highest incidence followed by U-shaped then V-shaped one. Morphometrically, type (III) notch was the most prevalent in both dry bones and cadavers, while the incidence of type (II) was the lowest form. Also, the measurements of superior transverse diameter, middle transverse diameter and vertical dimension of the different types of the notch showed no side or sex significant difference. The suprascapular foramen with ossified superior transverse scapular ligament (STSL) was seen in 5.8% of dry bones and 10% of cadaveric specimens. Fan and band-shaped ossified transverse scapular ligaments were reported. Absence of SSN was seen in 10.8% of dry bones, 7.5% of male and 10% of female specimens with left side predominance. V-shaped, absence, and ossified STSL were considered as predisposing factors of suprascapular nerve entrapment syndrome. Knowledge of the morphology and morphometric parameters of SSN is of great clinical significance for anatomists, radiologists, physiotherapists, orthopedics and neurosurgeons to perform good diagnosis and best planning for surgical or arthroscopic interventions within the shoulder region.
