From 1979 to 1994, reparative and recons tructive surgery were used to repair the war injuries of skins, bones, blood vessels and nerves of the limbs in 800 cases. A systematic clinical study was carried out. Many new operative methods were used and the results of treatment were good. Innovations and modifications were made in technique. In 120 cases of warin juries having soft tissues defects including skin and muscles, various tissue transplantations were used with the hope to accomplish onestaged repair of the defect and reconstruction of motor function of muscle. To those infections of bone and joint in war injuries, following early eradication of infected focus, transplantation of musculocutaneous flap or omental graft was immediately carried out with the aim to obtain primary healing of the wound. In the treatment of bone defects from war wounds with loss of skin and muscles, the vascularized skeletocutaneous graft was used. In the treatment of 150 cases of injury of peripheral nerve from forearms, the result of good to fair rated 68.8 percent for upper extremity and that for lower extremity, it was 62.2 percent. Following the early repair of 500 cases of injury of peripheral blood vessels, the patency rate of the blood vessel was 90 percent. The result following by pass vascular graft in the treatment of forearms injury of blood vessels even with very poor local condition was still very successful.

OBJECTIVE: To summarize the application of simple skin traction technique in repair of soft tissue defect of limb. METHODS: From 1999, 42 cases of soft tissue defect of limbs were repaired by simple skin traction technique instantly; the defect area ranged from 2.5 cm x 2.0 cm to 8.0 cm x 6.5 cm. RESULTS: The soft tissue defect less than 8.0 cm can be sutured instantly. All of the wound achieved primary healing without infection and necrosis of skin edge, the circulation and sensation of limbs were normal; healing time was 10 days to 16 days, 12.8 days on average. Thirty-two cases were followed up for 6 months; the shape and function recovered well. CONCLUSION: Simple skin traction technique is a good option to repair the soft tissue defect of limbs.
Objective To investigate the clinical effects of repairing massive bone defects in limbs by using vascularized free fibular autograft compoundingmassive bone allografts. Methods From January 2001 to December 2003, large bone defects in 19 patients (11 men and 8 women, aging from 6 to 35 years) were repaired by vascularized free fibular transplant with a monitoringflap compounding massive deep frozen bone allografts. The length of bone defects were 12 to 25 cm (16.6 cm on average), of vascularized free fibular 15 to 28 cm (18.3 cm on average), and of massive bone allografts 11 to 24 cm (16.1 cm on average). Thelocation of massive bone defects were humerus in 1 case, femur in 9 cases and tibia in 9 cases. Results After followup of 5 to 36 onths (18.2 months on average), wounds of donor and recipient sites were healed at Ⅰstage, monitoringflaps were alive, no obvious eject reaction of massive bone allografts was observed and no complications occurred in donor limbs. The radiographic evidence showed union in 15 patients 3 months and 3 patients 8 months after operation. One case of malignant synovioma of left lower femur recurred and amputation was performed 2.5 months after surgery. Internal fixation was removed in 5 patients, and complete bone unions werefound 1 year postoperatively. No massive bone allografts was absorbed or collapsed. Conclusion With strict indication, vascularized free fibular autograft compounding massive bone allografts, as an excellent method of repairing massive bone defects in limbs, can not only accelerate bone union but also activate and changer the final results of massive bone allografts from failure.
Objective To explore devising and clinical effect of ladder-shaped osteotomy and guide apparatus. Methods From February 2002 to January 2004, with the application of guide apparatus devised,the ladder-shaped osteotomy was designed and completed by bone drill and linear saw. The experiment of ladder-shaped osteotomy was carried out on a fresh bone trunk amputated. Clinically, 3 cases were replanted by shortening humerus by means of laddershapedosteotomy. The lengths of bone shortened were 3 to 7 cm. The bone length of ladder-shaped osteotomy was 2 to 3 cm. Two cases of radius defect was repaired with free fibula. The lengths of bone transplanted were 7 and 11 cm. The bone length of ladder-shaped osteotomy was 1 cm. Results It took 2 to 3 minutes to complete the laddershaped osteotomy on the two ends of bone defect. The ends of ladder-shaped osteotomy was integrated closely. All 5 cases were followedup for 10 to 16 months. All fractures healed during 14 to 20 weeks. Of 3 cases shortening humerus, the function of elbow joint was normal in 1 case, the activity range of elbow joint was 0 to 100° in 1 case,and 0 to 80° in 1 case, respectively. Of 2 cases undergoing fibula transplantation, the function of wrist and elbow joint were normal;the pronation and supination ranges of the forearm was 30° and 40° in one, 50° and 45° in the other. Conclusion With the introduction of guide apparatus, the laddershaped osteotomy by bone drill and linear saw is a recommendable procedure because of many advantages such as simple apparatus, shortcut, laborsaving and precision.
ObjectiveTo investigate the expression changes of the receptor activator of nuclear factor-κB ligand (RANKL) in the peripheral blood of patients with aseptic loosening of the implant after total hip arthroplasty (THA) by comparing with that of patients with femoral neck fracture and to analyze the correlation between RANKL expression and aseptic loosening. MethodsBetween January 2008 and January 2013,the peripheral blood were harvested from 58 patients with aseptic loosening of the implant after THA (trial group) and 63 patients with femoral neck fracture (control group).The 2 groups were well matched,with no significant differences in age and gender (P>0.05).The expressions of the RANKL mRNA and RANKL protein were evaluated by quantitative real-time PCR and Western blot respectively.At the same time,the concentration of RANKL was also measured by ELISA. ResultsThe expression of the RANKL mRNA in the trial group was 18.30±1.09,which was significantly higher than that of control group (1.00±0.05)(t=125.390,P=0.000).The relative RANKL protein expression values in trial group and control group were 0.856±0.254 and 0.404±0.102 respectively,showing significant difference (t=13.032,P=0.000).The results of ELISA showed that the concentration of RANKL in trial group [(3.553 5±0.129 7) ng/mL] was significantly higher than that of control group [(1.912 3±0.126 2) ng/mL] (t=18.124,P=0.000). ConclusionThe high RANKL expression in peripheral blood is probably correlated with aseptic loosening of the implant in patients undergoing THA,which possibly is the prognostic factor of aseptic loosening of the implant.
OBJECTIVE: To summarize the importance of surgical management to repair vascular injury in limbs salvage, and to analyze the influence factors in the management. METHODS: From 1993 to 2000, 42 cases of 58 vascular injuries were reviewed; there were 37 males and 5 females, aging from 12 to 70 years old. Emergency operations were performed in 38 cases and selective operations in 4 cases from 1 hour to 45 days after injury. There were 22 cases of complete rupture in 32 blood vessels, 5 cases of partial rupture in 6 blood vessels, and 15 cases of vascular defect in 20 blood vessels, with 5 cm to 10 cm defect. The operation management included end-to-end anastomosis in 22 cases, side-to-end anastomosis in 1 case, vascular repair in 5 cases and vascular grafting in 14 cases. All of the cases were followed up for 6 months to 7 years. RESULTS: In those received emergency operations, it was successful in 35 cases, with amputation in the other 3 cases; after operation, there were 5 cases of post-operative angio-crisis, 1 case of hematoma and 1 case of pseudoaneurysm. In those received selective operation, all succeeded but 1 case of post-operative angio-crisis. After the follow-up, except for 3 cases of amputation, the other limbs survived; and function of the survived limbs recovered satisfactorily after operation except poor recovery in 7 cases of replantation of the limbs. CONCLUSION: To repair vascular injury immediately, to manage angio-crisis and to remove influence factors is the key to save the injured limbs and to maintain the function of them.
