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.
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 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.
Objective To explore the application of intramedullary nail fixation combined with auxiliary plate and bone cement in the palliative treatment of pathologic fracture of extremities caused by metastatic tumors. Methods Clinical data of 11 cases with pathologic fracture of extremities caused by metastatic tumors between April 2015 and October 2016 were retrospectively analyzed. All the patients were treated by intramedullary nail fixation combined with auxiliary plate and bone cement. There were 6 males and 5 females with an age of 54-72 years (mean, 62.9 years). The disease duration was 1.0-1.5 months. Of the 11 patients, 4 metastatic tumors were diagnosed at humerus, 6 at femur, and 1 at tibia, respectively. And the tumor infiltration length ranged from 3.3 to 5.6 cm (mean, 4.6 cm), the depth could reach the bilayer of limb bones. All the patients had suffered the limbs pain and incapability of physical movement. The preoperative visual analogue scale (VAS) score was 6.36±1.03, and the Karnofsky Performance Status (KPS) score was 42.73±10.09. The operation time, intraoperative blood loss, and postoperative complications were recorded. The VAS score, KPS score, and Musculoskeletal Tumor Society (MSTS) score were used to evaluate the effectiveness at 3 months after operation. Results The operation time was 1.1-1.8 hours (mean, 1.5 hours), the intraoperative blood loss was 102.5-211.3 mL (mean, 135.6 mL). Postoperative limb incisions healed well without infection, necrosis, and delayed healing or other complications. All the patients were followed up 7-10 months (mean, 8.2 months). At 3 months after operation, the functions of limbs recovered. The VAS score decreased to 0.82±0.75 and the KPS score increased to 85.45±5.22, both showing significant difference when compared with preoperative ones (t=35.218, P=0.000; t=–18.470, P=0.000); and the MSTS score was 23.91±2.47. At last follow-up, the anteroposterior and lateral X-ray films showed that all the limbs healing well and no breakage of intramedullary nail and steel plate, or loosening in bone cement, limb shortening, malalignment, or other complications occurred. Conclusion In treating metastatic tumors of extremities, the combination of intramedullary nail fixation with auxiliary plate and bone cement will contribute to an invariable length and fixed location for limbs, resulting in biomechanical stability for skeleton. Under this premise, the tumor lesions can be eliminated and pathological pains be relieved, so as to improve patients’ life quality.
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.
