Innervation of the clavicular part of the deltoid muscle by the lateral pectoral nerve

Abstract

Introduction: The innervation pattern of the clavicular head of the deltoid muscle and its corresponding topography was investigated via cadaveric dissection in the present study, focusing on the lateral pectoral nerve. Materials and methods: Fifty-eight upper extremities were dissected and the nerve supplies to the deltoid muscle and the variability of the lateral pectoral and axillary nerves, including their topographical patterns, were noted. Results: The clavicular portion of the deltoid muscle received a deltoid branch from the lateral pectoral nerve in 86.2% of cases. Two topographical patterns of the lateral pectoral nerve were observed, depending on the branching level from the brachial plexus: a proximal variant, where the nerve entered the pectoral region under the clavicle, and a distal variant, where the nerve entered the pectoral region from

Could C3, 4, and 5 Nerve Root Block be a Better Alternative to Interscalene Block Plus Intermediate Cervical Plexus Block for Patients Undergoing Surgery for Midshaft and Medial Clavicle Fractures? A Randomized Controlled Trial

“…Traditionally, nonsurgical methods have been recognized as the initial treatment modality for most clavicle fractures. However, recent studies have shown that surgical intervention may be more beneficial to patients [ 12 , 32 ]. Recent developments in regional anesthesia have led to a renewed interest in analgesia with a cervical plexus blockade for clavicle fracture surgery.…”

“…The peripheral nerves innervating the clavicle include branches of the axillary nerve, suprascapular nerve, and lateral thoracic nerve (C5, 6, and 7) [ 5 , 12 ]; the supraclavicular nerve (C3 and 4) [ 27 ]; branches of C2 to 3 [ 8 ]; the medial and lateral thoracic nerves (C8 to T1) [ 17 ]; and the subclavian nerve (C5 and 6). Theoretically, patients undergoing plate fixation for a clavicle fracture feel pain or discomfort unless all the associated nerves (C2 to T1) are blocked.…”
