Summary

Clavicle fractures are a common orthopedic injury and make up 2.6%-5% of all fractures. Despite the benefits of operative management, post-operative chest wall paresthesia is a well-known complication among surgeons and is well described in the literature. Studies reporting on the natural history of post-operative paresthesia report an incidence of chest wall numbness anywhere from 10-80% and this is attributed to iatrogenic injury of the branches of the supraclavicular nerve that provide sensation over the clavicle, anteromedial shoulder and proximal chest. While this may seem like an easy complication to avoid, anatomic studies give insight into the complex and unpredictable branching of the supraclavicular nerve. The aim of this study was to compare the area (cm2) and change in size over time of post-operative paresthesia (includes hypesthesia and dysesthesia) following ORIF of displaced clavicle fractures between nerve-sacrificing and nerve-preserving procedures.

Detailed description

This is a prospective, partially-blinded, single center, randomized controlled trial to compare the post-operative outcomes of paresthesias and morbidity between nerve-preserving and nerve-sacrificing procedures after surgical fixation of clavicle fractures. Although prior studies explore different incision orientation, most fail to specify whether or not the supraclavicular nerve branches were identified and protected and also lack a patient questionnaire that focuses on paresthesia characteristics and patient quality of life as it relates to the measured area of postoperative numbness. In this proposed study, the investigators will be able to fill this gap in knowledge and give insight into whether or not a nerve-sparing technique should be used to decrease the morbidity of postoperative chest wall paresthesia following operative fixation of clavicle fractures. This research will be important to the scientific community because it will help guide a physician's pre-operative counseling and establish realistic expectations for their patients. It could also guide a physician's surgical technique in a manner to decrease post-operative morbidity for patient's undergoing surgical fixation of clavicle fractures. 1. Group 1 - Operative treatment utilizing a supraclavicular nerve-sacrificing procedure 2. Group 2 - Operative treatment utilizing a supraclavicular nerve-preserving procedure

Conditions

• Clavicle Fracture

Interventions

Type	Name	Description
PROCEDURE	Nerve-sacrificing procedure	Surgical fixation of the clavicle fracture will be performed through a horizontal incision over the clavicle. During the incision and soft tissue dissection, the surgeon will not attempt to identify the supraclavicular nerve branches. Instead, the surgeon will cut the nerve branches during the dissection.
PROCEDURE	Nerve preserving procedure	Surgical fixation of the clavicle fracture will be performed through the same horizontal incision over the clavicle. The surgeon will attempt to dissect out, identify and preserve all branches of the supraclavicular nerve throughout the fracture reduction, fixation and closure.
