OBJECTIVE In order to increase the survival area of pedicled fasciocutaneous flap, a multiple pedicled blocking randomized fasciocutaneous flap was designed. METHODS From January 1991 to September 1998, this technique was used to repair 33 cases, including 27 males and 6 females and the ages ranged from 6 to 58 years. All of the patients were suffered from traffic accidents. In these cases, 22 cases had skin defects of legs and feet with bone, nerve and tendon exposed, 5 cases had osteomyelitis as well as internal fixaters exposed and the other 6 had deformity from scar. The size of the flap was 25.0 cm x 13.0 cm x 2.4 cm at its maximum and 6.0 cm x 3.5 cm x 1.5 cm at its minimum. Based on the traditional blocking flap, according to the severity of the wound and conditions of the neighboring tissues, a flap having 2 to 4 orthogonal pedicles with a width of 1.5 to 3.0 cm was designed. The medical-graded stainless steel sheet was implanted below the deep fascia, and after blocking for 3 to 6 days, the side pedicles were divided. 6 to 14 days later, one of the two remaining pedicles was divided and was transferred to repair the defect. RESULTS 31 cases were followed up for 6 months to 5 years without any trouble of the joints. The flap had a good external appearance and was high pressure-resistant. CONCLUSION The multiple pedicled blocking randomized fasciocutaneous flap increased the size of the flap and the length to width ratio. It had the following advantages: manage at will, high resistance to infection and a large survival area of flap.
Objective To study the method and effect of free rectusabdominis muscle flaps with intermediate split thickness skin graft in repairing defects on legs and ankles.Methods From May 1998 to December 2002, 11 cases of defects on legs(2 cases) and on ankles( 9 cases) were repaired by use of unilateral free rectus abdominis flap with skin graft. The soft tissue defects were accompanied by osteomyelitis or the exposure of bone or tendon.The disease course was 1 month to 10 years. The defect size ranged 3 cm×4 cm to 8 cm×14 cm. The area ofrectus abdominis muscle flaps was 4 cm×6 cm to 8 cm×15 cm. Results All patients were followed up 6 months to 4 years after operation. All rectusabdominis flaps survived with good appearances and functions.The primary healing was achieved in 8 cases, intermediate split thickness skin graft necrosed in 3 cases and the wound healed after skin re-graft.Conclusion Free rectus abdominis flap is a proper option for repair of the soft tissue defects or irregular woundson legs and ankles. It has the advantages of abundant blood supply, b anti-infection ability, good compliance and satisfied appearance.
ObjectiveTo analyze the clinical features of Legionella-associated cavitary pneumonia, and to explore the diagnosis, treatment planning, and clinical management of patients.MethodsThe data of a patient with severe Legionella-associated cavitary pneumonia were collected and analyzed. Databases including PubMed, Ovid, Wanfang, VIP and Chinese National Knowledge Infrastructure were searched for pertinent literatures, using the keyword "Legionella, lung abscess or cavitary pneumonia" in Chinese and English from Jan. 1990 to Jun. 2019. The related literature was reviewed.ResultsA 60-year-old male patient was admitted to hospital because of fever, cough, and expectoration for five days. On presentation, his temperature was 38.3 °C, and pulmonary auscultation revealed rales on the left side of the lungs. Culture of lower airway secretions obtained by bronchoscopy revealed Legionella pneumophila infection, and serotype 6. Chest computerized tomography showed a consolidation in the left lung and an abscess in the left upper lobe. The patient was discharged from the hospital after three months of anti-Legionella treatment (Mosfloxacin, Azithromycin, etc.). Fifteen manuscripts, including 18 cases, were retrieved from databases. With the addition of our case, a total of 19 cases were analyzed in detail. There were 15 males and four females, aged from 4 months to 73 years old. Most of them (14/19, 73.7%) were accompanied by multiple underlying diseases. Initial empiric antimicrobial therapy failed in 15 (78.9%) cases, and 7 (36.8%) patients required combination therapy. The courses of antimicrobial treatment were from 3 to 49 weeks. All except one patient were fully recovered and discharged from hospital.ConclusionsLegionella pneumonia with pulmonary abscess or cavity is rare and often presents with fever. Pulmonary imaging shows infiltration in the initial, but can be free of cavities or abscesses. Most patients have basic diseases. Severe patients often need to be treated in combination with antibiotics for long periods of time.
Tissues defect of the sole of the foot requires a high quality of repair, because the sole bears the body weight most. Once there is loss of soft tissues and skin from the sole, the os calsis and the plantar fascia will be exposed. The use of vascularized tissue flaps to cover the beare area of the sole has been generally recognized. From May, 1985 through May, 1994, 26 cases of extensive tissue defects of the soles were treated. During the primary debridement, the wounds were repaired primarily by using retrograde island skin flap from the medial side of the leg with the posterior tibial artery. From the follwup, the results weresatisfactory. The advantages were: the skin flap had rich blood supply, large skin flap was avallable, the thickness of the flap was appropriate, and the elasticity or the weight bearing was good. Besides, the location of the artery was constant, and the operative technique was easy to handle and could be done in onestage with high survival rate of the skin flap.
【Abstract】 Objective To investigate the method to avoid lengthening lower limbs after total hip arthroplasty in patients with congenital short femoral neck. Methods The clinical data were analyzed retrospectively from 38 patients undergoing unilateral total hip arthroplasty between April 2005 and December 2010. There were 26 males and 12 females, aged 45-78 years (mean, 62.3 years). Among these cases, there were 11 cases of avascular necrosis of the femoral head, 17 cases of hip osteoarthritis, and 10 cases of femoral neck fracture. Before operation, 29 cases had leg length discrepancy; and the shortened length of the legs was 10-24 mm with an average of 14.5 mm by clinical measurement, and was 11-25 mm with an average of 14.7 mm by X-ray film measurement. The Harris score before operation was 44.0 ± 3.6. Results At 1 day after operation, 3 cases had legs lengthening by clinical and X-ray film measurement; limb length difference less than 10 mm was regarded as equal limb length in the other 35 patients (92.1%). All incisions healed by first intention, and no complication of infection or lower limb deep venous thrombosis occurred. In 3 patients who had legs lengthening, 1 patient had abnormal gait and slight limping after increasing heel pad because the lower limb was lengthened by 16 mm, and 2 patients had slight limping. The other patients could walk normally and achieved pain relief of hip. Thirty-six patients were followed up 12-68 months (mean, 43.8 months). The Harris score was 86.7 ± 2.3 after 6 months, showing significant difference (t=3.260, P=0.031) when compared with that before operation. The X-ray films showed no prosthetic loosening or subsidence. Conclusion For patients with congenital short femoral neck during total hip arthroplasty, the surgeons should pay attention to osteotomy plane determination, limb length measurement, and use of the prosthesis with collar to avoid the lengthening lower limbs
Objectives To investigate the clinical therapeutic effect of tibial boneskin flaps in the repair of infective boneskin defects of the leg. Methods Between February 2000 and March 2005, 68 cases of leg infective wounds with tibial bone and skin defects were treated: 4 cases using free grafting, 64 cases using crossleg or ipsilateral transposition grafting of tibial boneskin flaps so that the tibial support continuity of the affected leg could be reconstructed and the wound could be covered at one stage. The skin flap area ranged from 9 cm×4 cm to 25 cm×12 cm and the bone flap length ranged from 6 cm to 21 cm. Results The flaps were completely survived in 67 of the 68 cases except 1 case which was repaired by fibular boneskin flaps because of the failed blood-vessel anastomosis; the bone flaps were healed in 66 cases,except 1 case which had delayed union of the proximal end through 6month follow-up because tibial bone flap was lengthened, leading to long soft tissue stripping of the proximal end. All the 68 patients were followed up 6 months to 5 years. The leg function and contour weresatisfactory 2 years after operation. Those patients followed up more than 2 years showed normal weight loading walking without obviously abnormal gait, and can engaged in original work. Conclusion On the basis of sufficient antiinfection, the onestage reconstruction of tibial support continuity and the covering of wound by the three methods are suitable for many types of leg bone and skin defects, have a great application value and high successful rate and can retain the affected limb and create the conditions for the functional recovery.
ObjectiveTo discuss the effectiveness of free anterolateral thigh flap pedicled with medial sural vessels for treatment of leg skin and soft tissue defects. MethodsBetween July 2008 and January 2014, 32 cases of serious skin and soft tissue defects in the leg were repaired by using free anterolateral thigh flap pedicled with medial sural artery and vein. Of them, there were 22 males and 10 females, aged 23 to 50 years (mean, 36.5 years). Defects were caused by traffic accidents injury in 9 cases, crash injury of heavy object in 15 cases, and machine twist injury in 8 cases. The left side was involved in 10 cases and the right side in 22 cases. The mean interval of injury and admission was 2.5 hours (range, 1-4 hours). The location was the upper, middle, and lower one third of the anterior tibia in 15 cases, 10 cases, and 7 cases respectively. The area of defect ranged from 10 cm×5 cm to 23 cm×9 cm. After debridement and vaccum sealing drainage treatment, the anterolateral thigh flap ranging from 12 cm×7 cm to 25 cm×11 cm pedicled with the medial sural vessels was used to repair the wound. The donor site was sutured directly or repaired with the skingrafts. ResultsAll flaps and skingrafts survived after operation, and primary healing of wound was obtained. After 6-23 months (mean, 14.5 months) follow-up, all flaps were characterized by soft texture, good color, and satisfactory appearance. The sensation of the flaps were recovered to S2~S3+ according to the Britain's Medical Research Council criteria at 6 months after operation. No obvious scar contracture was observed at donor site. ConclusionThe medial sural artery has the advantages of constant anatomical position, large diameter, rich blood flow, and a long artery pedicle, so the medial sural vessels is an ideal choice as recipient vessels for the reconstruction of leg skin and soft tissue defect.
Objective To investigate the cl inical results of treating leg open fracture with soft tissue defect by pedicle flap transfer in combination with external fixator. Methods From May 2004 to June 2007, 12 cases of leg open fracture with soft tissue defect, 9 males and 3 females aged 18-75 years, were treated. Among them, 8 cases were caused by traffic accidents, 2 crush, 1 fall ing and 1 mechanical accident. According to the Gustilo Classification, there were 2 cases of type II, 5 of type IIIA and 5 of type IIIB. There were 2 cases of upper-tibia fracture, 3 of middle-tibia and 7 of middle-lower. The sizes of soft tissue defect ranged from 5 cm × 3 cm to 22 cm × 10 cm.The sizes of exposed bone ranged from 3 cm × 2 cm to 6 cm × 3 cm. The course of the disease was 1-12 hours. Fracture fixation was reached by external fixators or external fixators and l imited internal fixation with Kirschner wire. The wounds with exposed tendons and bones were repaired by ipsilateral local rotation flap, sural neurocutaneous flap and saphenous nerve flap. The size of selected flap ranged from 5 cm × 4 cm to 18 cm × 12 cm. Granulation wounds were repaired by skin grafting or direct suture. Results All patients were followed up for 6 months to 2 years. All patients survived, among whom 2 with the wound edge infection and 1 with the distal necrosis were cured by changing the dressing, 8 with pin hole infection were treated by taking out the external fixator, 1 with nonunion received facture heal ing after bone graft in comminuted fracture of lower tibia, 2 suffered delayed union in middle-lower tibia fracture. The ROM of ankle in 3 cases was mildly poor with surpass-joint fixation, with plantar extension of 0-10° and plantar flexion of 10-30°, while the others had plantar extension of 10-20° and plantar flexion of 30-50°. Conclusion The method of pedicle flap transfer combined with external fixator is safe and effective for the leg open fracture with soft tissue defect.
Objective We aimed to investigate the attitude and suggestion from doctors, pharmacists and civil servants concerning brain death and organ transplantation and the legislation. Methods A questionnaire with 10 sections and 44 questions was designed and distributed. The effective questionnaire data was then recorded and checked for descriptive analysis. Results In 1 400 questionnaires distributed, 1 063 were responded and 969 of them were valid and analyzed. The respondents showed an incomplete understanding of brain death and organ transplantation laws. Seventy-four percent of the respondents recognized and accepted the standard of brain death. They agreed that legislation should be involved in the removal of organs for transplantation, the future use of the organs, and insurance and compensation for the donor for possible health risks induced by organ removal. Of the 969 respondents, 92% considered it necessary to have legislation in brain death and organ transplantation, and 61% thought that it is time to legislate. Conclusion Legislation for brain death and organ transplantation is urgent and timely in China. The laws must include the respective rights and obligations of patients, close relatives, and medical institutions. Educating the public about brain death and organ transplantation should also be encouraged in a variety of ways.
The ultra length and width random calf fasciocutaneous flaps whose blood supply came from the calf fasciocutaneous vascular network were transposed in 9 cases for the treatment of severe trauma of leg. All of the flaps survived except one having necrosis of the distal fourth. The length and width of the flap to the width of the pedicle were 6.1∶1 and 2.7∶1 respectively. Properly extended the area and decreased of blood perfusion of the flan would reduce the burden of the venous backflow to the flap relatively. The abundant vascular networks of the calf fasciocutaneous flap was a very important factor that this type of flap would possibly survive.
