Summary

The optimal analgesic peripheral nerve block (or combinations thereof) are undefined for clavicle fractures, the most frequent fracture in the human population. This goal of this study is to determine whether interscalene block (ISB), superficial cervical plexus block (SCPB), or both provide the best analgesia for lateral and midshaft clavicular fractures, respectively.

Eligible Conditions
  • Collarbone Fracture
