説明

Background: The objective of this research is to survey the incidence and course of supraclavicular nerve injury following surgery for midshaft clavicular fractures.<BR>Methods: The study enrolled 30 patients who underwent surgery for midshaft clavicular fractures between 2009 and 2011 and who were observed for at least 3 months. The average observation period was 9.7 months (3--20 months). The surgery involved either plate fixation or percutaneous pinning. Plate fixation was used in 12 patients (6 males, 6 females) with an average age of 49.3 years at the time of surgery (16--73 years). Pinning was used in 18 patients (14 males, 4 females) with an average age of 36.7 years at the time of surgery (16--63 years). Patient consultation notes and medical records were used to assess whether these patients experienced postoperative hypoesthesia in the supraclavicular nerve region.<BR>Results: In the plate fixation group, 8 patients (67%) experienced postoperative hypoesthesia (of which, 3 patients experienced anesthesia). At the time of the final survey, 5 patients had made a full recovery, but 3 patients were left with mild hypoesthesia. In the pinning group, 3 patients (17%) experienced postoperative hypoesthesia, and 1 patient was left with hypoesthesia.<BR>Discussion: Supraclavicular nerve injury following clavicular fractures is thought to involve the type of injury received (direct external force delivered), the degree of dislocation at the fracture site, and iatrogenic injury. Particular care needs to be taken during surgery when plate fixation is selected.
