High Velocity Projectile에 의한 上肢의 말초신경 손상
장종호 최신의학사 1977 最新醫學 Vol.20 No.8
Both low and high velocity projectiles which either directly or indirectly damage the nerve cause not only severe injury in the path of the wound but -will extend several centimeters. This type of trauma can also cause gross destruction of nerves and other tissues, which lead to scarring thus a poor bed for, the during its repair. This paper emphasizes that the high velocity injury even though the nerve has its continuity, a burning and/or concussion may cause severe destruction of its sheath and cell mass. Even though nerve has retained its continuity it should be explored if it dose not return to normal function within an expected time. An end-to-end anastomosis or nerve graft should be done after complete resection of damaged nerve segment. This paper examine 87 cases of nerve damage due to gun shot wound with result as follow; A) Nerve with continuity; 35 cases (40.2%) which included 11 median nerve, 12 ulnar n., 9 radial n., mixed nerve injury median and ulnar were 3 cases. B) Nerve without continuity; 52 cases (59.8%) which included 16 median nerve, 17 ulnar n., 14 radial n., mixed injury median and ulnar were 5 cases. Mixed nerve injury median and ulnar n. 1 case in the upper arm, and 7 cases in the forearm. The time for spontaneous recovery of the upper arm injuries were average 5 weeks in the musculocutaneous n., 8 weeks (4-9 wks) for the radial n., 10 weeks (6-12 wks) for the median n., and 12 weeks (8-18 wks) for the ulnar n.. Pathological changes of the damaged nerve observed by light and electron microscope which showed blistering and edematous swelling 1.5 cm at both proximal and distal portion. Nerve injury by indirect effect revealed degeneration of the nerve tissue and occlusion of the vaso nervorum 1.2 cm in length. This study indicates that in both severed or unsevered nerve resulting from gun shot wound we should wait for specific period of time prior to surgical repair to receive maximum functioning of the extremity.

The Giant cell tumor is quasi-malignant in nature. Therefore, clinically there are many complica?tions in its progress. The natural complications are metastasis, pathological fracture, recurrence, and death. The post operative complications are local recurrence, seeding, non-union and post-operative infection, etc.. . The choice of treament is generally known to be segmental resection with or without bone graft. The preventive measurement for tumor recurrence is needed which consist of en block excision inc?luding healthy soft tissue 0.5-1.0 cm wide from capsule of the tumor. Through the experiences in trea?ting a case of the soft tissue recurrence of the giant cell tumor in distal radius which is treated by autogenous fibular replacement bone graft after segmental resection, it is stressed that tumor surgery is more to be radical than palliative surgery, and the review of literatures concerning the recurrence and its treatment is done.
