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 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.

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.
To summarize the effectiveness of the improv ed surgical techniques in fasciocutaneous flaps of the limbs. MethodsFrom February 1999 to December 2005, 58 patients (39 males, 19 females, aged 1068 years) underwent repairs of the skin defects with improved fasciaocu taneous flaps of the limbs. Twentyone patients had the skin defects in front of the tibial bone in the middle and lower parts, 12 patients had the skin defect s in the heels, 16 patients had the skin defects in the ankles, 3 patients had t he skin defects around the knees, 1 patient had a wide sacrococcygeal bedsore, and 5 patients had the skin defects in the wrists and hands. The wounds ranged in size from 5 cm×3 cm to 18 cm× 12 cm. According to the wound lo cations, the following flaps were selected: 4 cutaneous antebrachii medialis nerve and basilic vein fasciocutaneous flaps, 1 cutaneous antebrachii lateralis nerve and cephalic vein fasciocutaneous flap, 3 saphenous nerve and great saphenousvein fasciocutaneous flaps, 1 cutaneous nerve of thigh posterior fasciocutaneous flap, 32 reverse sural nerve and saphenous vein fasciocutaneous flaps, and 17 reverse saphenous nerve and great saphenous vein fasciocutaneous flaps. The dissected flaps ranged in size from 6 cm× 4 cm to 18 cm× 13 cm. The donor wounds underwent straight sutures in 39 patients, and the skin grafting (6 cm×3 cm to 13 cm× 6 cm) was performed on 19 patients after the donor wounds were closed. Results The wounds healed by first intention, and the flaps survived completely in 54 patients. The flaps developed partial necrosis in 4 patients. The followup for 120 months (average, 8 months) revealed that the flaps had a satisfactory appearance with a soft texture and the function was also satisfactory. Conclusion A fasciocutaneous flap of the limbs is an ideal flap for repairing defects in the skins and soft tissues of the limbs. The survival rate of the flap can be further improved by an improvement of the surgical techniques.
ObjectiveTo explore the effectiveness of free profounda artery perforator flap (PAPF) in the posteromedial femoral region for the treatment of traumatic skin defects of limbs.MethodsBetween March 2015 and April 2017, 11 cases of traumatic limb skin defect with deep tissue exposure were treated with free PAPF in posteromedial femoral region. There were 7 males and 4 females, with an average age of 39 years (range, 26-54 years). There were 4 cases of upper limb skin defect and 7 cases of lower limb skin defect. The causes of injury included 6 cases of traffic accident injury, 3 cases of machine crush injury, and 2 cases of crush injury. The size of wounds ranged from 11 cm×7 cm to 18 cm×11 cm. The time from post-traumatic admission to flap repair were 4-9 days (mean, 7.3 days). The size of free PAPF ranged from 15 cm×9 cm to 22 cm×13 cm. The donor site of 8 cases were closed directly; 3 cases could not be closed directly, and skin grafting was used to cover the wound.ResultsThe time of skin flap harvest was 40-90 minutes (mean, 47 minutes). All flaps and skin grafts survived and the wounds healed by first intention. All the 11 patients were followed up 6-19 months (mean, 12 months). The skin flaps were soft in texture, similar in color to the skin around the injured limbs, without obvious pigmentation and hair overgrowth. Three of them underwent second-stage skin flap thinning. At last follow-up, the limb function of all patients recovered well. Longitudinal scar could be seen in the donor site of the flap, and the location was concealed. All patients did not complain that scar of the donor site affected their sexual life during the follow-up.ConclusionFree PAPF can achieve satisfactory results in repairing skin defects of extremities. The flaps have the advantages including constant perforator branches, simple operation, and concealed donor site.
Objective To repair defects at both ends of theblood vessels with a considerable disparity in the diameter of the both sides or with a large diameter in extremities by phleboplasty of branched and double autogenous veins. Methods Three kinds of phleboplasties——funnel-shaped, raincape-shaped and transposed Y-shaped were designed. Experiments in fresh blood vessels in vitro were completed successfully. These methods were used clinically to repair injured external iliac veins, femoral arteries and veins, and popliteal arteries and veins, to replant severed fingers and to transplant toenail flaps on thumbs by harvesting autogenous great saphenous veins,small saphenous veins and forearm veins in 36 cases, including 35 cases in emergency operation and 1 case in selective operation.The length of grafted blood vessels ranged from 1.0 cm to 15.0 cm. Results The phleboplasties of funnel-shaped could enlarge the diameter by 1.0-1.25 times inanastomotic stomas. The phleboplasty of raincape-shaped could enlarge the diameter large enough to meet the demands for various blood vessels in extremities. The phleboplasty of transposed Y-shaped could provide large vein transplants. In36 grafted veins, 35 were in patency. The blood supply in extremities was normal.ConclusionThe funnel-shaped and raincape-shaped phleboplasties of branched veins can enlarge the anastomotic stomas of grafted veins. The transposed Y-shaped phleboplasty of double femoral veins is an ideal way to repair injured primaryblood vessels with a considerable disparity in the diameter of the both sides or with a large diameter in extremities.
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 cl inical effect of anterolateral thigh pedicle or free perforator flap in repairing soft tissue defect in the extremities. Methods From March 2000 to January 2009, 32 cases of soft tissue defect were treated with pedicle or free anterolateral thigh perforator flap. There were 30 males and 2 females with an median age of28 years (4-53 years). Soft tissue defects included left radial side in 3 cases, the left lateral elbow in 1 case, knee in 5 cases, calf in 14 cases, dorsal is pedis in 5 cases, and planta pedis in 4 cases. The defect area ranged from 9 cm × 6 cm to 15 cm × 13 cm. Nine cases compl icated by bone defect and 1 case by radial nerve defect. The time from injury to hospital ization was 1 hourto 4 months (mean 5 days). Defects in 27 cases were repaired by anterolateral thigh perforator flap, simultaneously combined with transplantation with the second toe in 1 case, with sural nerve using arterial ized small saphenous vein in 1 case, nd with fibular or il ium in 4 cases. Defects in other 5 cases were repaired with flaps pedicled with superior lateral genicular artery. Neuroanastomosis was performed in 14 cases of the flaps. The size of the flaps ranged from 10 cm × 8 cm to 16 cm × 15 cm. Skin defects at donor site were repaired with spl it thickness skin graft or sutured directly. Results All patients were followed up from 8 months to 9 years with an average of 18 months. The flaps survived well and the wounds healed by first intention in 29 cases, 3 flaps necrosed and cured after symptomatic management. Skin graft at donor site survived completely in 9 cases. The color and texture and thickness of the flaps were similar to those of recipient site. After 6 months, the sensation of the flaps recovered to grade S3-4 in 14 patients whose cutaneous nerve were anastomosed, partial recovery was observed in other patients. In 4 patients receiving transplantation of fibular or il ium, the bony heal ing was achieved within 4 to 6 months. No obvious dysfunction was found at the donor site. Conclusion The pedicle anterolateral thigh perforator flap is long and thick with constant location. Anastomosis or transferring is easy to perform. It can provide big area and feel ing recovery by nerve anastomosis. It is an effective method to repair soft tissue defect of the extremities.
