Objective:
To study injuries involving brachial plexus and its branches.
Methods:
66 cases collected from 2003 to 2005 in our department were analyzed statistically.
Results:
94% of injuries involved young adult males; 94% were blunt force injuries; 34% involved both nerve and bone mainly involving ulnar nerve and ulnar bone (50%); 40% of the injured nerves received electromyogram and 15 nerves were diagnosed with injuries clinically.
Conclusion:
Forensic determination on severity of brachial plexus injuries mainly depends on movement recovery of limb. The best time for forensic appraisal is 20 d post operation+L (length of nerve severed distally)/R (growth rate)+90 d.
