Ultrasound-guided selective supraclavicular nerve block combined with modified clavipectoral fascial plane block for midshaft clavicule fracture surgery: a case report

The SSCPB technique achieves optimal anesthesia for mid-clavicular fracture surgery by combining SSNB with MCPB. This approach effectively prevents diaphragmatic paralysis and upper limb dysfunction, making it particularly suitable for patients with concomitant cardiopulmonary injuries or comminuted fractures. Characterized by its simplicity in operation and high safety profile (avoiding general anesthesia-related risks), SSCPB reduces opioid dependence and promotes postoperative recovery. However, more extensive clinical research is required to establish its long-term safety and efficacy profile, particularly in complicated acromioclavicular joint dislocations where adjunctive sedation or suprascapular nerve blocks might be indicated.
