OBJECTIVE: To define how to preserve the severed limbs to prolong the period of replantation. METHODS: The original articles about preservation of severed limbs in recent years were reviewed, it was suggested that the period of replantation was determined by the injury of skeletal muscle. RESULTS: When the environment of severed limbs was changed, the injures of skeletal muscle could be decreased. CONCLUSION: After the severed limbs are reasonably preserved, the period of replantation may be prolonged.
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.
ObjectiveTo investigate multidisciplinary collaborative role in the treatment of patients with lower extremity degloving injury. MethodsThe wound therapy group and the Department of Orthopedics, Nutrition, and Psychology, and the Pain Clinic and Rehabilitation team collaboratively carried out the comprehensive intervention for a patient with lower extremity degloving injury in March 2013 in our hospital. The wound therapist was responsible for correct evaluation, debridement, infection control, maintaining moisture balance, and protecting wound edges of the skin; The wound team members were responsible for the entire treatment and healing process in the form of text and photos; Department of Orthopedics was responsible for secondary skin graft; Nutrition division was responsible for the correction of anemia in patients with hypoalbuminemia; Psychological service was responsible for psychological counseling as treatment accident sometimes brought psychological trauma; Pain outpatient service was responsible for consultation, formulating specific plans to control and relieve the patient's pain, and promote the patient's physical and mental rehabilitation process; Rehabilitation division was responsible for the guidance of patients on lower limb function exercise, prevention of knee joint rigidity, muscle stiffness, to promote the functional recovery of lower limbs. ResultsThe patient's wound was healed completely without scar or joint contracture. Function of lower limbs recovered to normal. Patients was very satisfied to the treatment, and had a total full recovery of body and mind, and returned to the family and society. ConclusionMultidisciplinary collaboration treatment for patients with lower extremity degloving injury can ease pain, eliminate psychological barriers, promote wound healing, and maintain the limb function.
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.
Objective? To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture. Methods Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the cl inical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main cl inical manifestations included lameness and abnormal gait. The medical examination showed pelvic obl ique and relative inequal ity of lower l imbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic obl ique. The CT scans showed no abnormal finding except pelvic obl ique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabil itation exercise. Results All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic obl ique, and 2 patients had obvious pelvic obl ique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation. Conclusion Unilateral gluteal muscle contracture leads to pelvic obl ique and inequal ity of lower l imbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and rehabil itation exercises.
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.
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 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.
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.
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.
