920 cases with peripheral nerve injuries those who were seen in Hanyang University Hospital :MG laboratory during a period January 1972 - October 1983 were evaluated for the causes.
This study revealed that the causes were traumatic, occupational and pathological factors ocally or systemically. And many of them could be prevented if a certain caution was made
3 nerves of upper extremity and 2 nerves of lower extremity those nerves most frequently .ffected were evaluated and the causes were discussed.
In 204 median nerve injuries evaluated (Table 1-1), laceration and penetration injuries was nost common cause (51.5 %) and the next common cause was compression and traction injuries ,33.8%). The later group(69 cases) was evaluated again for the details. As table 1-2 shown ;he carpal tunnel syndrome was most frequent cause(76.8%) and 5 other various causes were :ncountered.
In 219 ulnar nerve injuries evaluated (table 2-1), laceration was most frequent(46. 6%) and the next frequent causes were compression and traction injury(15. 1%). The later group, (33 cases) was evaluated again for the details. As the table 2-2 shown simple compression at the elbow was in 60.6% and 4 other causes were encountered.
In 162 radial nerve injuries evaluated(table 3-1), fracture of the humerus was the most frequent(37. 0%), and the next frequent cause were compresion and traction injuries (19.8%). The later group(32 cases) was evaluated again for the details. As the table 3-2 shown simple compression at the humerus was in 62.5% and 5 other causes were encountered.
In 303 peroneal nerve injuries evaluated(table 4-1), compression & traction injury and IM injection the gluteal region were the 2 most frequent causes(16.8%, 16.8%). , The former group(51 cases) was evaluated again for the details. As the table 4-2 shown compression at. the fibular neck was in 54.9% and 6 other causes encountered.
In tibial nerve injuries evaluated(table 5-1), IM injection injury was the most frequent cause (25.0%). and compression injury was in 9.4%. The later group(3 cases) was evaluated
again for the details. As the table 5-2 shown massive edema of leg with CO intoxication in 66.6% and the other was due to a prolonged cramp of calf.
