Objective To investigate the outcome of repairing hand composite defects using pedicle osteocutaneous groin flap. Methods From February 1998 to May 2004, 33 cases of hand composite defects were repaired with pedicle osteocutaneous groin flap. There were 22 males and 11 females. The age was 19 to 54 years with an average of 243 years. The defect was caused by palmar penetrating injury in 17 cases, by dorsal hand crushing injury in 9 cases and by other injury in 7 cases. Twentythree cases complicated by metacarpal defect, 10 by phalanx defect. Thesize of skin defect was 3.5 cm×2.0 cm to 15.0 cm×10.0 cm, the size of bonedefect was 1.5 to 3.5 cm. After 3 to 7 days of primary debridement, defect was repaired by the pedicle osteocutaneous groin flap based on the superficial circumflex iliac vessels. The flap size was 4.0 cm×2.5 cm to 17.0 cm×11.0 cm. Results All the osteocutaneous flaps survived. During the 4 to 22 months follow-up postoperatively, thetexture, appearance and function of the flap were excellent and bone union was obtained in all cases after 7 to 9 weeks of operation.Conclusion The pedicle osteocutaneous groin flap is an ideal flap to repair the composite defect of the hand, with the benefit of simple procedure and reliable blood supply.
OBJECTIVE: To discuss the method to repair the defects of palm with the improved flaps pedicled with the dorsal carpal branch of ulnar artery. METHODS: The improved flaps were designed on the basis of anatomical distribution of the dorsal carpal branch of ulnar artery and the medial antebrechial cutaneous nerve, the ulnar artery was ligated and cut at the beginning of its dorsal carpal branch. The flap pedicled with dorsal carpal branch including the distal ulnar artery was achieved and applied clinically to repair 15 cases of the skin and soft tissue defects of palm from August 1997 to November 2001. The size of flaps ranged from 7 cm x 5 cm to 12 cm x 8 cm. RESULTS: All of the cases were followed up 3 weeks to 6 months, and the flaps completely survived. There was no ischemia and necrosis at the distal part of flaps and the appearance and function was satisfactory. CONCLUSION: The improved flap has long vascular pedicle, abundant blood supply and sensitive sensation, so it can be used to repair defect of palm.
During apt. 1986 to Dec. 1988. the axial flap methodwas used for the treatment of the congenital blakker exstro-phy. The preliminary is reported in this paper. This group in-cluded 10 patients, 4 men and 6 women, and their agesranged from 4 to 20. Seven patients had experienced 1-3 op-erations with failure to repair the exstrophy or to urinarycontinence before admission to our hospetal. Using the axialflap method only 1 in 10 cases can not control the urinationwell, the others achive well the requcirement of functional bladder. The longest follow-up pcriod has lasted for more than 2 years. and the renal and bladder function ars completely normal. the axial flaps of the present method included skin flap, facial and vascular pedicles of 8 types. The application of the flaps has developed a new serjies of procedures that ars suitable for the treatmen of a varicty of extrophy deformities.
A new method of transfer of the nasolabial skin flap, the myocutaneous flap with pediculated guadratus labii superioris muscle was introduced. It was applied in 9 cases mid-face defects with satisfactory results. The applied anatomy and the its operative technique were briefly discussed.
Objective To investigate and evaluate prevention and treatment of seroma by transposition of tissue flaps and Arista hemostatic powder after regional lymph node resection in patients with malignant tumors. Methods Twelve patients (6 males, 6 females; aged 31-81 years, with metastatic tumors underwent prevention and treatment of seroma with the tissue flaps and Arista hemostatic powder spray after regional lymph node resection. The metastatic tumors involved the axilla in 1 patient with breast carcinoma, the iliac and inguinal regions in 2 patients with carcinomas of theuterine cervix and the rectum, and the inguinal region in 9 patients, including4 patients with malignant fibrous histiocytoma（3 in the thigh, 1 in the leg）,2 patients with squamous carcinomas in the leg, 1 patient with synovial sarcomain the knee, 1 patient with epithelioid sarcoma in the leg, and 1 patient with malignant melanoma in the foot. As for the lymph node removal therapy. 1 patientunderwent axillary lymph node removal, 2 palients underwent lymph node removal in theiliac and inguinal regions, and 9 patients underwent lymph node removal inthe inguinal region. Meanwhile, of the 12 patients, 6 patients underwent transpostion of sartourius flaps with Arista hemostatic powder, 3 patients underwent transposition of the rectus abdominis myocutaneous flaps (including 2 patients treatedwith Arista spray befor the wound closure and 1 patient treated by transposition of local skin flaps with Arista spray used again),and 3 patients underwent only the suturing of the wounds combined with Arista. At the same time, of the 12 patients,only 4 patient underwent the transplantation of artificial blood vessels. Results The follow-up for 2-10 months after operation revealed that 10 patients, who had received the transposition of tissue flaps and the spray of Arista hemostatic powder, had the first intention of the incision heal with seroma cured. Nine patients were given a preventive use of Arista hemostaticpowder and therefore no seroma developed. The combined use of the transpositionof tissue flaps and Arista hemostatic powder spray achieved a success rate of 100% in the prevention or treatment of seroma. However, 1 patient developed microcirculation disturbance 24 hours after operation and underwent disarticulation of the hip; 1 patient developed pelvic cavity hydrops and died 10 months after operation. Conclusion The combined use of transposition of tissue flaps and Arista hemostatic powder spray can effectively prevent or treat seroma after regional lymph node removal in a patient with malignant tumor.
