  • REPAIR OF LARGE BONE DEFECT DUE TO EXCISION OF BONE TUMOR WITH BONE ALLOGRAFT

    OBJECTIVE: To study the reparative and reconstructive methods for the large bone defect due to the excision of bone tumor. METHODS: According to the size and shape of the bone defect, we selected the proper bone and joint or manipulated bone segment of the profound hypothermia freezing allograft and gave locked intramedullary nails or steel plate and screws for stable internal fixation. RESULTS: In the 22 cases, 20 survived without tumor and 2 died. One patient treated with the allograft of semi-knee joint was found rejection. Then the wound did not heal. After the skin flap grafting was performed, the wound still did not heal, so the patient accepted amputation(4.5%). In the other 21 cases, the X-ray and 99mTc SPECT showed some callus or concentration of nuclein which implied bone union. According to Markin bone graft criterion, the excellent rate of function recovery was 81.8%. CONCLUSION: Allografting of bone and joint is a good and workable method in repairing and reconstructing the bone defect due to the excision of bone tumor. It should be further studied and be applied.

  • REPAIR AND RECONSTRUCTION OF TRAUMATIC DEFECT OF MEDIAL MALLEOLUS IN CHILDREN

    Object ive To inves t igate the operat ive method and cl inical ef fect of repai r ing and reconstructing the traumatic defect of medial malleolus in children with complex tissue flap of vascularized fibular head epiphysis. Methods From July 2003 to December 2007, 8 children with defect of medial malleolus due to wheel injury were treated, including 5 boys and 3 girls aged 2-10 years old. The medial malleolus were completely defected (5 cases at left foot and 3 cases at right foot) and combined with the skin defect around the medial malleolus (4.0 cm × 2.0 cm - 9.5 cm × 5.5 cm). The time from injury to hospital admission was 6-8 hours in 2 cases, and 24-168 hours in 6 cases. The complex of vascularized fibularhead epiphysis and tissue flap was adopted to repair the defect. The flap 4.5 cm × 2.5 cm - 10.0 cm × 6.0 cm in size and the fibular head epiphysis 2.5-3.0 cm in length were harvested. The donor site was sutured directly. Results All wounds healed by first intention, all the composite tissue flap survived with good blood circulation, all the epiphysis of medial malleolus healed within 6-9 weeks, and all the donor sites healed well. All the child patients were followed up for 1-5 year. The color and elasticity of the flaps were good, without cicatricial contracture. The patients had no inversion of ankle joint, with satisfying loading and walking function. Six cases had normal flexion and extension of the ankle and 2 cases were l imited sl ightly (dorsiflexion 10-20°, plantarflexion 35°). Talus has no inner move and ankle joint had no eversion. Seven cases were graded as excellent and 1 as good according to the standard of American Orthopaedic Foot amp; Ankle Society. For the medial malleolus, no premature closure of epiphysis occurred, and the center of ossification grew gradually and well developed l ike the contralateral side. The donor knee joint had normal flexion and extension function, without inversion and instabil ity. Conclusion The complex of vascularized fibular head epiphysis and tissue flap can repair the epiphysis and soft tissue defect of medial malleolus in children at one stage, and the reconstructed medial malleolus can develop with the growth of children. It is a satisfactory method of reconstructing the traumatic defect of medial malleolus in children.

  • REPAIR AND RECONSTUCTION OF ORAL AND MAXILLOFACIAL DEFECT——CLINICAL ANALYSIS OF 1 973CASES

    Objective To compare the reconstructive method of oral and maxillofacial defect with free tissue flaps. Methods The clinical materials were collected from 1 973 reconstructive cases between January 2000 and June 2004 and analyzed in terms of the distribution of age, gender,disease type, defect location, reconstructive method and the incidence of vascular crisis of free flaps as well as success rate of free flap respectively. SAS 6.12 was adopted for statistical analysis. Results A total of 1 973reconstructive cases includded 764 in middle age (>45 years to ≤60 years, 38.72%), 527 in old age (>60 years, 26.71%), 450 young adults (>28 years to ≤45 years, 2281%), 187 in young age (>14 years to ≤28 years, 9.48%) and 45 children(≤14 years, 2.28%). The ratio of male to female was 1.5∶1. The ratio of benign to malignancy lesion was 1∶1.94. The tongue defect accounted for 20.63%, followed by mandibular defect(1738%), parotid defect(13.74%),buccal defect(12.72%), maxillary defect(8.16%), oral pharynx defect (7.60%), floor of mouth defect(5.68%) and others (14.09%). Vascular free flap transfers accounted for 45.82%(90.4), followed by axial flap(38.17%,753), random flap(10.19%,201), avascularizedbone graft (1.52%, 30) and others(4.30%, 85). The most frequently used flap was the forearm flap(594 cases), followed by the fibula free flap(143 cases) and the pedicled pectoralis major myocutaneous flap(369 cases); these three flaps accounted for 56.06% (1 106/1 973).In 47 free tissue flaps(5.20%) having vascular crisis, 30 were saved (63.83%). The success rate of total free tissue flaps was 98.19%(923/940). Conclusion The majority of reconstructive cases of oral and maxillofacial defects is the middle aged andthe old aged male patients with malignancy. The tongue defect accounts for about one fifth of all the cases. The vascularized free flap has a high success rate, so it is a main method for reconstruction of oral and maxillofacial defects. The forearm flap, the fibular free flap and the pedicled pectoralis major myocutaneous flap are the main management for repairing oral and maxillofacial defects.

  • RECONSTRUCTION OF CHEST WALL AFTER RESECTION

    Objective To evaluate the results of chest wallreconstruction (CWR) in patients who underwent chest wall tumor resection accompanying huge chest wall defect. Methods From Jan. 1998 to Mar. 2003, 31 patients underwent CWR. Among them, 20 were male and 11 female. The age ranged from 8 to 72 years.The indications for resection were primary chest wall tumor in 21 patients, lung cancer with invasion of chest wall 6, recurrence of breast cancer 2, radiationnecrosis 1 and skin cancer 1. The number of rib resected was 2~7 ribs (3.6 in average). The defect was 20~220 cm2 (97.1 cm2 in average). Concomitant resectionwas done in 13 patients, including lobectomy or wedge resection of lung 10, partial resection of diaphragm 2, and partial sternectomy 1. Seven patients underwent soft tissue reconstruction alone(latissimus dorsi+greater omentum, latissimusdorsi myocutaneous flap, latissimus dorsi muscle flap), 5 patients bony reconstruction alone(Prolen web), and simultaneous BR and STR were performed in 19 patients(latissimus dorsi, pectorails major, latissimus dorsi+fascia lata, and Prolene web). Results Three patients (9.7%) developed postoperative complications. Postoperative survival period was 6~57 months with a median of 22 months. Conclusion A favorable clinical outcome can be achieved by CWR for the patients with hugechest wall defects that result from resection of chest wall tumors. 
