OBJECTIVE: To study the clinical result of treating firearm-wound with the vessel pedicel tissue flap. METHODS: From May 1992 to October 2000, 21 cases of firearm-wound of upper limbs underwent transplantation with the vessel pedicel tissue flap. Of them, the locations of the wound were upper arm in 11 cases, forearm in 7 cases, hand in 3 cases. The size of wound was 1.0 cm x 0.5 cm to 8.0 cm x 6.5 cm; the wound course was 3 minutes to 8 hours with an average of 3 hours and 30 minutes. The patients were followed up 3 months to 2 years. RESULTS: In 21 cases, the results were excellent in 19 cases and poor in 2 cases. The good rate was 90.5%. CONCLUSION: Treatment of firearm-wound with vessel pedicel tissue flap has the good effect.
OBJECTIVE: To investigate the availability and effect of skin stretch in closing the firearm injured soft tissue defect. METHODS: Eight white pigs with firearm injured soft tissue defect were divided into 3 groups. Each group I and group II had 3 pigs which were performed skin stretch. The control group had 2 pigs without stretch. The average diameter of the defect in three groups was (7.3 +/- 0.2) cm, (9.1 +/- 0.3) cm, (7.3 +/- 0.2) cm respectively, and the site of defect was on the lateral thigh and buttock. RESULTS: Skin stretch could make a visible reduction of the wound. It was possible to close the wound by direct traction when the diameter of the buttock wound was less than 7 cm, and when the diameter of the lateral thigh wound was less than the radius of thigh. The skin stretch should not last more than 7 days and the best effect appeared in 4 to 5 days after performing the skin stretch. CONCLUSION: The skin stretch can be applied in the repair of the firearm injured soft tissue defect. It has many advantage compared with the tradtional treatment.
The causes of development of 56 cases of bone defects from firearm injuries of extremities were analyzed, and the advantages of transfer of vascularized iliac bone graft with deep iliac circumflex vessels in 28 cases and the indications of transfer of vascularked fibular bone graft with fibular vessel in 15 cases and the exporiences in 9 cases from the methed of transter of seapula-cutaneous composite graft were summarized. It was emphatically pointed out that the half-circle typo externa fixators had its unique advantages in the treatment of the bone defects of long bones of extremities from firearm injuries. It would enentually become the method of priority for the treatment of fractures, nonunion of fractures and bone defects of extremities from firearm injuries.
From 1989 to 1991, eighteen cases of the metacarpal bony loss from war injury were treated in Africa. Their ages ranged from 17～56 years old. Fourteen patients were injuried from gunshot; another four were injuried from blast. All of the eighteen were performed with W shape wire, and these can be done as early as 4～16 hours after the initial injuries. The author introduced the way of making W wire and the important points of the surgical technics. We suggest that the key to the successful operation is the good debridement,covertage of wound with healthy soft tissue and the good drainage.
From March 1979 to February 1987, 500 cases of firearm wounds of blood vessels were treated. Of them, 465 cases were recovered, 15 cases were disabled, 13 cases had amputation, and 7 cases died. The article presented the clinic materials. The following problems were discussed: (1) The characteristics of firearm wounds of blood vessels. (2) Emergency treatment of injuries of major blood vessels of limbs. (3) Indications of repair of blood vessels. (4) The methods of repair of defect in blood vessel. (5)Factors influencing the survival of extremities, and (6) Active prevention and treatment of complication.
Successrui treatment o? ? cases o? softtissue defect of the hand after explosive in-juries have been achieved by using free skinflap. Three to seven days after emergency de-bridement, repair was then carried out bytransfer of free vascularized anterolateralfemoral skin flap (in 4 cases) and lateralskin flap of the leg (in 2 cases). An experi-ence was introduced for primary repair of de-fect of the dorsum of the hand from a pene-trating injury by a skin flap of which the skin of the central portion was removeed with the preservation of the subcutaneous tissue and fascia.
