Background: The suprascapular notch (SSN) varies anatomically and may affect nerve entrapment risk. This study examines SSN variations in scapulae of Slovak origin using Rengachary's and Polguj's classifications. Materials and methods: We examined 111 dried scapulae, measured key SSN dimensions and classified SSN using Rengachary's and Polguj's systems, followed by statistical analysis. Results: According to Rengachary's classification, Type II (32.43%), Type III (29.73%), and Type IV (22.52%) represent most common SSN shapes. Suprascapular foramen was present in 5.41% and a rare occurrence of double suprascapular foramen was also observed. According to Polguj's classification, Type III was most frequent (72%), followed by Type I (13%); Type IV accounted for 5%. Statistically significant differences in morphometric parameters were demonstrated among most common Rengachary SSN types. Conclusions: Using Rengachary's and Polguj's classifications together allows for a detailed assessment of SSN variations in samples of Slovak origin. Certain SSN variations are associated with specific clinical relevance.
