he fascia lata substitute valve operation was performed for curing the supperficial varieositycaused by the deep vein incompotence of the lower extremity basing on the study of the sources ofblood supply and the vascular distribution features of the fascia lata. The fascia lata subetitute vein valve operations were done on three males with the age rangingbetween 22 and 44 years old, and the rerelts were satisfactory 2 and 6 months after oporation.
ObjectiveTo discuss nursing measures and experiences for children with extensive skin avulsion injury of lower limbs treated by vacuum sealing drainage (VSD).
MethodsWe reviewed the perioperative nursing data of 48 child patients with extensive skin avulsion injury in lower limbs who underwent VSD treatment between December 2010 to October 2012. And the data were compared with those for 56 children with the same disease and treatment between January 2007 and November 2010.
ResultsIn these 48 children, 19 received once, 23 received twice, and 6 received 3 times of vacuum sealing drainage. During the treatment, 5 drainage tubes were blocked and were solved with normal saline, and 3 drainage tubes had leakage and two of them were reconnected and the other one became normal after changing the dressing. For VSD, the time between being wounded and skin-grafting was 13.6 days, and the average hospitalization time was 24.3 days. Compared with the traditional method group, children in the VSD group had fewer drug changes during hospitalization, lower infection rate, and shorter hospitalization stay, and the differences were significant (P<0.05).
ConclusionKeeping drainage tube airtight, normal and effective is as important as nutrition and mental nursing in the treatment of children's extensive skin avulsion injury in lower limbs, which can decrease infection rate, reduce average hospitalization time, and increase operative efficacy.
Objective To investigate the feasibility and efficacy of transcatheter directed thrombolysis （TDT） approach in treatment for deep venous thrombosis （DVT） of lower limbs and as compared with trans-dorsal pedis vein thrombolysis （TPVT） approach. Methods The clinical data of 437 patients with acute DVT （184 males and 253 females） at the age of （43±12） years （range 19-76 years） from July 2008 to January 2012 in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively. Patients in the group TDT received TDT were 293 cases， 32 inferior vena cava filters were implanted. Patients in the group TPVT received TPVT were 65 cases， 4 inferior vena cava filters were implanted. Results The resolution time of thrombus in the group TDT was shorter than that in the group TPVT （6 d versus 9 d， P＜0.05）. The circumference difference of leg or upper leg before and after treatment in the TDT group was significantly greater than that in the TPVT group （P＜0.05）. The rate of venous patency was （65.2±15.4）% and preservation rate of valvular function was （78.2±12.6）% in the group TDT， and which was （63.8±16.3）% and （91.1±10.7）% in the group TPVT， respectively. The differences of venous patency rate was not statistically significant（P＞0.05） between two groups， but the prevervation rate of valvular function was significant difference （P＜0.05） .Hematomas in 3 cases and gross hematuria in 4 cases were observed， and displacement of inferior vena cava filter occurred in 1 patient in the group TDT. The gums bleed or gross hematuria in 5 cases were observed in the group TPVT. Conclusions Both TDT and TPVT can effectively relieve symptoms. TDT can shorten the course of disease， but itincreases functional damage of the deep vein valvular.
Objective To improve the knowledge of inflammatory bowel disease complicated with venous thromboembolism for better diagnosis and treatment. Methods One case of patient with ulcerative colitis complicated with a multiple vessel thromboembolism ( pulmonary arterial, deep vein of lower limb, and superior mesenteric vein) was analyzed, and related literatures were reviewed. Results The patient resulted in pulmonary thromboembolism ( PTE) recurrence because of irregular treatment. In addition to deep vein thrombosis of the lower extremity, a new discovery of the superior mesenteric vein embolism ( MVT) was diagnosed. The bleeding risk of heparin or lowmolecular weight heparin ( LMWH) for treatment is low, while that of warfarin is high. Conclusions Venous thromboembolism ( VTE) has a close relationship with inflammatory bowel disease ( IBD) such as ulcerative colitis. The symptomis not so typical that it is easy to misdiagnosis and missed diagnosis. It is noted that mesenteric venous thrombosis ( MVT) should be excluded in IBD patients suffering from VTE, if the source of embolus is not clear. Suitable treatment should be considered according to the risk stratification of VTE and risk-benefit ratio because of a high bleeding risk.
Objective To explore the clinical effect of latissimus dorsi musculocutaneous flap with a few muscle in repairing the soft tissue defect of lower limbs. Methods From June 2000 to December 2006, 8 patients with soft tissue defects of lower limbs were repaired with the latissimus dorsi musculocutaneous flaps. There were 6 males and 2 females, aged from 2569 years. The locations were heel in 3 cases, dorsum pedis in 2 cases, anticnemion in 2 cases, and the right leg (squamous carcinoma) in 1 case. The area of soft defect ranged from 10 cm×7 cm～18 cm×12 cm. The flap in size ranged from 15 cm×8 cm to 22 cm×15 cm. Results Of all the flaps,6 survived,1 had vascular necrosis 2 hours after operation and survived by skin grafts, 1 had delayed healing because of infection. The wound and donor site achieved primary healing. The followup for 3 to 12 months revealed that all the flaps had a good appearance. The function of donor site was as normal. Conclusion It is an ideal method to repair the softtissue defect of lower limbs with latissimus dorsi musculocutaneous flap.
Objective To explore the feasibil ity, indications, and effects of vacuum seal ing drainage (VSD) combined with flaps for repairing skin and soft tissue defects of lower l imbs. Methods From June 2006 to November 2009, 15 patients with skin and soft tissue defects of lower l imbs were treated with VSD combined with flaps (VSD group, n=5) and only flaps (non-VSD group, n=10). In VSD group, there were 3 males and 2 females with an average age of 46 years (range, 32-69 years), including 3 cases of traffic accident injury, 1 case of skin necrosis after amputation, and 1 case of plate exposureafter operation. The locations were lower leg in 1 case, ankle in 2 cases, dorsum of foot in 1 case, and forefoot in 1 case. The defect size ranged from 6.5 cm × 6.0 cm to 23.0 cm × 17.0 cm. The disease course ranged from 2 hours to 2 months. In non- VSD group, there were 5 males and 5 females with an average age of 50 years (range, 23-58 years), including 6 cases of traffic accident injury, 1 case of crush injury in earthquake, 1 case of osteomyel itis, and 2 cases of plate exposure after operation. The locations were lower leg in 1 case, ankle in 3 cases, forefeet and dorsum of feet in 4 cases, and heel in 2 cases. The defect size ranged from 4 cm × 4 cm to 20 cm × 12 cm. The disease course ranged from 1 hour to 2 months. There was no significant difference in general data between 2 groups (P gt; 0.05). Results In VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (11.8 ± 9.5), (35.4 ± 28.3), and (47.2 ± 35.8) days, respectively; the size of flap was (232.8 ± 142.0) cm2; and the infection rate after VSD-use was 0. In non-VSD group, the preoperative hospital ization days, postoperative hospital ization days, and total hospital ization days were (25.8 ± 12.4), (33.9 ± 28.1), and (59.7 ± 32.4) days, respectively; the size of flap was (97.3 ± 93.6) cm2; and the infection rate after 8 to 14 days of regular therapy was 80%. There were significant differences in the preoperative hospital ization days and the size of flap between 2 groups (P lt; 0.05). All flaps were al ive except 3 partial necrosis (1 case in VSD group, 2 cases in non-VSD group). The 3 flaps healed by skin grafting and suturing. The donor sites healed by first intention. All patients were followed up 5-41 months (22.1 months on average). All flaps were good in color, texture, and wear abil ity. Conclusion It is effective to apply VSD combined with proper flap to repair skin and soft tissue defects of lower l imbs, which can cut down infection rate, improve blood supply, shorten the preoperative hospital ization days, and facil itate heal ing, but whether it can shorten the postoperative hospital ization days and total hospital ization days need further research.
Objective To evaluate the long-term function of the traumaticallydamaged joint after its repair with transplantation of a fresh or a frozen allogenic joint. Methods From March 1977 to September 1993, 13 patients (9 males, 4females; age, 17-55 years) with traumatically-damaged joints underwent transplantation of the fresh or the frozen allogenic joints. Five patients had 5 damagedmetacarpophalangeal joints, 6 patients had 9 damaged interphalangeal joints, and 2 patients had 2 damaged elbow joints. So, the traumatic damage involved 13 patients and 16 joints. All the metacarpophalangeal joints and the interphalangeal joints were injured by machines and the 2 elbow joints were injured by road accidents. The patients were randomly divided into 2 groups: Group A (n=7) andGroup B (n=6). The 7patients with 8 joints in Group A underwent transplantation of fresh allogenic joints; the 6 patients with 8 joints in Group B underwent transplantation of frozen allogenic joints. The allogenic joint transplants were performed in the period from immediately after the injuries to 6 months after the injuries. The motion ranges of the transplanted joints and the X-ray films were examined after operation, and the immunological examination was performed at 8 weeksafter operation. Results The time for synostosis was 5-8 months in Group A, but4-6 months in Group B. In Group A, at 2 years after operation the metacarpophalangeal flexion was 30-40° and the interphalangeal flexion was 20-30°; however,at 6 or 7 years after operation the interphalangeal flexion was only 10-20°. The patients undergoing the transplantation with fresh elbow joints had the elbowflexion of 60° and the elbow extension of 0°, and had the forearm pronation of 30°and the forearm supination of 30°. But in Group B, at 2 years after operation the metacarpophalangeal flexion was 6070° and the interphalangeal flexionwas 40-50°; at 6 or 7 years after operation the interphalangeal flexion was still 40-50°. However, the patients undergoing the transplantation with frozen elbow joints had the elbow flexion of 90° and the elbow extension of 0°, and hadthe forearm pronation of 45° and a forearm supination of 45°. The joint motion ranges, the Xray findings, and the immunological results in the patients undergoing the transplantation of the frozen allogenic joints were significantly better than those in the patients undergoing the transplantation of fresh allogenicjoints. There was a significant difference in the immunological examination between Group A and Group B (IL2, 21.64±3.99；CD4/CD8,3.88±0.82 vs.IL-2,16.63±3.11；CD4/CD8, 2.53±0.23, P＜0.01). Conclusion Repairing the traumatically-damaged joints with frozen allogenic joints is a better method of regaining the contour, movement, and complex motion of the hands.
Limb motor dysfunction is the most common sequela of stroke. Its recovery cycle is long and difficult, which has an important impact on the physiology and psychology of patients. Therefore, the recovery of limb motor function after stroke has become the focus and difficulty of current rehabilitation. Brain-limb coordinate regulation technology is a rehabilitation strategy that effectively promotes the recovery of limb motor function and brain function through the organic combination of rehabilitation technology with limbs as target organs and brain as target organs. Based on the brain-limb coordinate regulation technology, this paper will systematically elaborate its theory and application through literature review, and then provide a more reasonable and effective choice for the treatment of limb motor dysfunction in stroke patients.
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.
Stroke can lead to dysfunction of movement, sensation, cognition and other functions, eventually affect the quality of life of patients. Many patients suffer from severe and persistent upper limb dysfunction. Upper limb rehabilitation has always been a focus in clinical practice and scientific research of rehabilitation field. As an emerging technology, virtual reality (VR) provides simulated environments for patients to enhance their participation and experience, and has been more and more widely used in stroke rehabilitation. This paper reviews the application and research progress of VR in upper limb rehabilitation after stroke, discusses the current evidences based on both the independent application of VR and the application of VR combined with other rehabilitation interventions, and indicates that VR can play a positive role in promoting the upper limb strength and coordination of stroke patients and enhancing their motivation to participant in rehabilitation. In the future, more high-quality studies are needed to further confirm the efficacy and optimal parameter settings.
