Rudimentary Hypoplastic Suprascapular Notch with Posterior Groove Extension in a Nigerian Scapula

Abstract

Variations in size and shapes of Suprascapular Notch (SSN) are documented etiological factors associated with Suprascapular Nerve Entrapment Syndrome (SNES).

During routine bone collection for teaching purposes, a rudimentary hypoplastic “V” shaped SSN was found in a Nigerian scapula. The SSN extended posteriorly into a shallow groove which continued posteriorly as a curved ridge ending on a large nutrient foramen.

Knowledge of anatomical Variation of SSN is important for accurate localization of site of suprascapular nerve (SN) entrapment.

Keywords: rudimentary, hypoplastic, posterior groove, suprascapular notch.
