Objective To evaluate the application value of repairing the defects of the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis. Methods From January 2002 to June 2005, five patients with defects in the chest wall underwent the prothesis with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis under general anesthesia. Focal cleaning was performed first; then, the skin flap was designed and taken (15 cm ×10 cm); and finally, the defects of the chest wall were repaired with the muscle flap of the musculus rectus abdominis. Results Of the 5patients, 4 had the flap healing by the first intention, and 1 had the delayed healing, with no complication. The skin flap had a good appearance, without edema orpigmentation. The X-ray examination showed that the shadow of the sternal sequestrum disappeared. There was no recurrence or complication during the follow-upfor 1-3 years (average, 18 mon). Conclusion The repairing of the defects in the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis is a simple and effective surgical treatment for defects of the chest wall around the sternum, and this kind of treatment is worth applying extensively in clinical practice.
OBJECTIVE: To compare the effect of several types of rib rings with intercostal muscles for the replacement of trachea in thorax. METHODS: The surface layer of the third rib of dogs were ripped off and curved into triangular, quadrilateral and polygonal form. These three types of rib rings with intercostal muscles were used to replace a segment of trachea in thorax. RESULTS: The stability of triangular rib ring was very well, but stricture of ring were often happened because of its smaller internal diameter. These stability of quadrilateral rib ring was the worst. The polygonal rib ring presented the biggest diameter and good stability compared to the other two kinds of rings. If silicone tube was supplemented in the polygonal rib ring, the quality of artificial trachea was excellent. CONCLUSION: The rib rings with intercostal muscles are successfully used for replacing the defect of trachea in canine thorax. The polygonal rib rings have the best quality in the three types of rib ring for tracheal replacement.
Objective To evaluate the efficacy of transposition of the medial gastracnemius muscle flap in the limbsalvage operation of the proximal tibial tumors. Methods From January 2001 to September 2005, 13 patients (8 males,5 females; aged 14-57 years, averaged 29.7 years) suffering from the proximal tibial tumors were treated with a limbsalvage operation. Among them, there were 4 patients with osteosarcoma, 6 with malignant fibrous histocytoma, 1 with malignant giant cell tumor, 1 with synovial sarcoma, and 1 with Ewing’s sarcoma. According to the Enneking staging system, 1 case was in Stage ⅠB, 9 in Stage ⅡA, and 3 in Stage ⅡB. One or two cycles of neo-adjuvant chemotherapy were used to each of the patients before operation. All of the patients underwent the medial head of the gastrocnemius muscle flap transposition to reconstruct the soft tissues after resection of the tumors and reconstruction of the bone defect by prothesis or bone-graft or the two methods combined. Results The follow-up for 7-47 months (average, 19.2 months) in all the patients revealed that. there was no flap necrosis, no skin necrosis at the incision margins, and no infection or fracture of the implanted bone. The patient with malignant fibrous histocytoma died of systemic metastasis 20 monthsafter operation. The patient with Ewing’s sarcoma had a local tumor recurrence 18 months after operation; though treated with the focal cleaning and the bone cement filling, the patient still developed lung metastasis of the tumor 26 months after operation. The patient with osteosarcoma underwent amputation 12 months after operation because of the tumor recurrence. According to the function assessment by the Mankin system, there were 6 patients who had an excellent result, 4 had a good result, and 3 had a poor result, with a satisfaction rate of 77%. Conclusion The flap transposition of the medial head of the gastrocnemius muscle can reconstruct the soft tissue defect, decrease the local complication rate and improve the clinical outcome of the limb salvage for the proximal tibia malignant tumor.

ObjectiveTo summary the application and effectiveness of the posterior radial collateral artery (PRCA) compound flap in reconstruction of soft tissue defect after tongue cancer excision. MethodsBetween August 2011 and October 2011, 5 patients with squamous cell carcinoma underwent tongue defects reconstruction with compound flap with extended lateral arm free flap (ELAFF) and triceps muscle flap (TMF) after ablation in one-stage. All patients were male with an average age of 59 years (range, 43-71 years). The disease duration was 25-60 days (mean, 42 days). After extended resection, 3 cases had 1/3 tongue and mouth floor defect, and 2 cases had 1/2 tongue and mouth floor defect. The size of ELAFF ranged from 7 cm × 5 cm to 9 cm × 5 cm, and the size of TMF ranged from 3 cm × 3 cm to 4 cm × 4 cm. The donor sites were directly sutured. ResultsAll compound flaps survived. The wounds at donor sites and recipient sites healed primarily. The patients were followed up 6 months. After operation, the tongue had good appearance and motion; the patients had clear voice and no dysphagia. No recurrence was observed during follow-up. Local numbness appeared at the donor sites, but the function of the elbows was normal. ConclusionThe application of the compound flap of ELAFF and TMF based on PRCA perforator is a better option to reconstruct tongue defects for its reliable blood supply, appropriate thickness, easy operative procedures, and less complication.
Objective To explore a surgical method for chronic osteomyel itis of sternum after thoracotomy. Methods From January 2006 to February 2009, 11 cases of chronic osteomyelitis after thoracotomy (2 cases of coronary bypass, 6 cases of mitral valve replacement, and 3 cases of ventricular defect repair) were admitted. Of them, there were 6 males and 5females, aged from 6 to 62 years (median 34 years), including 6 cases of simple osteomyelitis of sternum, 2 cases of osteomyelitis of sternum with suppurative infection of mediastinum, and 3 cases osteomyel itis of sternum with costal chondritis. Necrotic sternum were excised and defect was from 4 cm × 3 cm to 7 cm × 4 cm. Greater pectoral muscle flap was designed from 8 cm × 5 cm to 10 cm × 6 cm on one side and was transferred to defect. Negative drainage and sensitive antibiotics were administered after operation. Results Healing by first intention was achieved in 10 patients except 1 patient who had a few discharge at the drainage outlet and whose incision healed 1 week later. The follow up was from 3 to 10 months with an average of 6 months. The formed scars were flat with soft texture in 8 patients and moderately hypertrophy in 3 patients. The wounds healed without pain, relapse or abnormal function of donor upper limb. Conclusion Transplantation of greater pectoral muscle flap is an effective way to repair chronic osteomyelitis of sternum after thoracotomy.
