    • VASCULAR PEDICLE ELONGATION TECHNIQUE IN ANTEROLATERAL THIGH ISLAND FLAP TRANSPLANTATION

      To introduce a new technique for vascular pedicle elongation in the anterolateral thigh island flap transplantation and evaluate the outcome of this technique in the clinical application. Methods From January 2003 to January 2006, 6 patients (5 males, 1 female; age, 1849 years) were admitted for surgical operation because of the soft tissue defect around the knee joint. The soft tissue defect after the injury was found in 3 patients, the defect after the removal of the softtissue tumor in 1, and the defect after the prosthetic replacement in the knee joint in 2. The soft tissue defects ranged in size of 8 cm×4 cm to 15 cm ×6 cm. When the anterolateral island flap of the thigh underwent the reverse transplantation, the ascending branch of the lateral circumflex femoral artery was used as a nutrient vessel for the flap, and the descending branch of the lateral circumflex femoralartery was separated to the distal part. The main trunk of the lateral circumflex femoral artery was ligated at the point that was proximal to the furcation ofthe ascending and decending branches so that the vessel pedicle of the flap could be lengthened and then the defect was repaired.The flaps ranged in size of 10cm×6 cm to 18 cm×8 cm Results All the flaps were successfullytransferred in the 6 patients. The lengthened pedicle ranged in length from 8 to 12 cm, with an average of 10 cm. There was no vascular crisis after operation. All the transferred flaps survived, with a color and texture similar to those in the recipient site. The postoperative followup for 6-18 months revealed that the motion range of the knees was satisfactory. Conclusion The vascular pedicle elongation technique can enlarge the application scope of the anterolateral thigh island flap and the survival rate of the flap is not influenced by any factor.

    • TRANSPLANTATION OF THE PALMARIS LONGUS TENDON WITH A VASCULAR PEDICLE FOR THE COMPLEX INJURY OF THE DIGITAL FLEXOR TENDON

      In order to seek a good method to treat the severe, complex damage of the digital flexor tendon, an anatomical study based on 30 cadavers was done, and the result showed that the source of the blood supply to the palmaris longus tendon was from the radial and ulnar arteries. Three cases of severe complex digital flexor tendon injuries were satisfactory. Its main advantages were: (1) The tendon transplant had its own blood supply and had no need to the revascularization, therefore the adhesion formed between the tendon and adjacent tisues might be less;(2) Besides reparing the tendon defect, it can simultaneously solve the problem of the defect of the soft tissues and the skin.

    • Comparison of pedicled skin flap of foreskin for phalloplasty and Sugita surgical method in treatment of complete concealed penis

      ObjectiveTo evaluate the effectiveness of pedicled skin flap of foreskin for phalloplasty and Sugita surgical method in the treatment of complete concealed penis.MethodsThe clinical data of 46 children with complete concealed penis between January 2016 and January 2018 were analyzed retrospectively. Among which, 25 cases were treated with pedicled skin flap of foreskin for phalloplasty (group A) and 21 cases were treated with Sugita surgical method (group B) with an average age of 4.7 years (range, 2 years and 8 months to 11 years). At 3 months after operation, the concealed penis recovery was scored from three aspects of postoperative penis length (the difference of the penis length between at 3 months after operation and before operation), penis appearance, and skin appearance (the total score was 10). And the parents evaluation of satisfaction degree of penis exposure, penis appearance, and foreskin appearance after surgical correction was collected.ResultsEighteen cases (72.0%) in group A and 15 cases (71.4%) in group B were followed up with an average of 13 months (range, 3-36 months). The incisions healed well in both groups, and there was no flap dehiscence, infection, necrosis, and penile erectile dysfunction. The penile length of the two groups increased significantly at 3 months after operation (P<0.05); there was no significant difference between the two groups in terms of penis length and increased length at 3 months after operation and score of increase penis length after operation (P>0.05). No penile retraction occurred in the two groups. And there was no significant difference between the two groups in penis appearance score, but the penis appearance score, skin appearance score, and total score of group A were significantly better than those of group B (P<0.05). At 3 months after operation, the satisfaction rate of penis exposure in group A and group B was 88.9% and 80.0%, respectively, with no significant difference (χ2=0.50, P=0.48); the satisfaction rate of penis appearance was 72.2% and 53.3%, and the satisfaction rate of foreskin appearance was 94.4% and 53.3%, respectively, and the differences were significant (χ2=5.13, P=0.03; χ2=7.53, P=0.01).ConclusionBoth surgical methods are suitable for correction of complete concealed penis, and the penile length gets a satisfactory recovery. However, the lymphedema of the prepuce after Sugita surgical method is serious, which can easily lead to poor appearance of the penis after operation. In general, the effectiveness of pedicled skin flap of foreskin for phalloplasty is better than that of the Sugita surgical method.

    • THE ANATOMIC STUDY AND CLINICAL APPLICATION OF THE BONE (PERIOSTEUM) FLAP PEDICLED WITH UPPER MUSCULAR BRANCHES OF LATERAL FEMORAL MUSCLE

      OBJECTIVE: To explore the anatomic feature and clinical application of the bone (periosteum) flap pedicled with upper muscular branches of lateral femoral muscle. METHODS: The anatomic features and distribution of upper muscular branches of lateral femoral muscle were observed in the lower extremities of 40 adult cadavers. From February 1989 to February 1999, 7 cases with bone defect or nonunion of upper part of femur were treated with transfer of bone (periosteum) flap pedicled with upper muscular branches of lateral femoral muscle. RESULTS: The upper muscular branches of lateral femoral muscle originated from the transversal branch of lateral circumflex femoral artery. The musculoperiosteal branch and periosteal branch were originated at 16.8 +/- 3.0 cm below the greater trochanter. The diameter and length of musculoperiosteal branch were 1.4 to 1.7 mm and 2.7 to 5.6 cm, those of the periosteal branch were 0.4 to 0.6 mm and 1.2 to 1.5 cm respectively. Bone union achieved in 10 to 18 weeks after operation in all 7 cases after 18 to 42 months follow-up. The motion of hip joint reached 180 degrees in 4 cases, 120 degrees in 2 cases and 65 degrees in 1 case. The donor area recovered well. CONCLUSION: The bone (periosteum) flap pedicled with upper muscular branches of lateral femoral muscle is an effective alternative for repairing the bone defect or nonunion of the upper or middle part of femur.

        Objective?To investigate the operative method and efficacy of subcutaneous pedicle scar-band rotation flap in the treatment of cervical postburn scar contracture.?Methods?Between August 2008 and May 2010, 15 patients with cervical postburn scar contracture were treated with subcutaneous pedicle scar-band rotation flaps, including 9 males and 6 females with an average age of 17.3 years (range, 7-35 years). The disease duration was 1-8 years (mean, 3 years). The locations were the left cervical region in 6 cases, the right cervical region in 8 cases, and mental cervical angle region in 1 case. According to LI Ao’s classification standard for cicartrical contracture, there were 12 cases of grade I and 3 cases of grade II. The area of scar ranged from 8 cm × 5 cm to 25 cm × 12 cm. After scar relaxation, wounds were repaired with the subcutaneous pedicle scar-band rotation flaps of 7 cm × 5 cm to 15 cm × 10 cm at size. In 3 cases of grade II, free split thickness skin grafts (7 cm × 4 cm to 12 cm × 7 cm at size) were used simultaneously.?Results?After 2 weeks of operation, 2 scar-band flaps had distal partial necrosis and healing was achieved after dressing change with formation of hypertrophic scar; the others survived with healing of incisions by first intention. After 6-12 months of follow-up, all patients possessed good cervical contours, sufficient release of scar contractures, and normal cervico-mandicular or mental cervical angles. The skin’s color and texture were satisfactory. There was no recurrence of cervical scar contracture and other complications. All patients acquired normal cervical movement at last follow-up.?Conclusion?Subcutaneous pedicle scar-band rotation flap is a simple, efficient, and versatile technique in release of cervical postburn scar contracture. It is an effective method to make use of the lateral excess scar flap to resurface defects caused by scar release.
