Abstract

The suprascapular notch (SSN) is the typical site of compression and injury of the suprascapular nerve (SN), which results in a neuropathy known as suprascapular nerve entrapment. The SSN is enclosed from the top by the superior traverse scapular ligament (STSL), creating a tunnel for the SN. On the both sides of the suprascapular notch, below the STSL, the anterior coracoscapular ligament (ACSL) is found. This fibrous band can potentially narrow the opening and contribute to the occurrence of suprascapular entrapment syndrome. This study presents a first case of a bifid anterior coracoscapular ligament coexisting with atypical suprascapular nerve course that has never been described in the literature. Knowledge of such anatomical variations can be helpful in arthroscopic and open procedures of the suprascapular region and confirms the safety of operative decompression for entrapment of the suprascapular nerve.
