Clavicular fractures represent a common occurrence often necessitating effective pain management strategies, particularly following surgical interventions. This study involved a cohort of five patients who underwent clavicular fracture surgery under general anesthesia. A novel analgesic approach combining two distinct nerve block techniques-Serratus Posterior Superior Intercostal Plane Block (SPSIPB) and Clavipectoral Plane Block (CPB)-was employed for postoperative pain control. The procedural methodology encompassed the administration of SPSIPB preceding anesthesia induction, followed by CPB subsequent to induction. SPSIPB targeted specific neural regions responsible for sensory blockade within the innervation of the clavicular skin, whereas CPB focused on the clavipectoral fascia. Standard anesthesia protocols were utilized, and postoperative pain levels were evaluated using Numeric Rating Scores (NRS).
