Ten cases of basicranial repair and reconstruction after resection of malignant tumors in nasal sinuses invading base of skull were reported. Dural repair was performed when the resected basicranial osseous lamella was less than 3 cm in diameter; when the lamella ranged from 4 to 7 cm, bone graft was not required either, the defect was repaired with either fascia lata and pericranium of pedunculated galea aponeurotica or frontal myocutaneous. No leakage of cerebrospinal fluid, cerebral hernia and intracranial infection happened postoperatively.
Objective To elucidate the surgical indicationsand treatment outcome of total spondylectomy and reconstruction for thoracolumbar spinal tumors with neurological deficit. Methods From January 1999 to December 2005, 16 patients with thoracolumbar spinal tumors with neurological deficit were treated with total spondylectomy and reconstruction. There were 10 males and 6 females, with an average age of 31.5 years(16-62 years).There were 10 cases of primary tumors of spine (4 giant cell tumor of bone, 3 chondrosarcoma, 2 recurrent aneurysmal bone cyst, and 1 osteosarcoma), and 6 cases of solitary metastasis of thoracic or lumbar spine. Tomita’s surgical classification was as follows: 9 cases of type 4, 6 of type 5, and 1 of type 6. Frankel’s neurological classification was as follows: grade A in 1 case, B in 4, C in 7,and D in 4. All patients were treated with total spondylectomy and reconstruction through combined anterior and posterior approach. Results All patients were followed up from 10 to 63 months with an average of 27.5 months. Pain was relieved completely in all patients. The neurological function returned to grade D in 5 cases, to grade E in 11 cases. Among the 10 patients with primary spinal tumor, nine patients survived with tumor-free, and one with osteosarcoma died because of lung metastases 18 months after surgery. Among the 6 patients with spinal metastasis, three patients survived with tumorfree, and lung metastasis occurred in 1 case 10 months after surgery, two died because of multiple metastases of internal organs 10 months and 32 months after surgery. Conlusion Total spondylectomy and reconstruction is a safe and effective surgery for thoracolumbar spinal tumors with neurological deficit, with pain relief, neurological improvement and minimum tumor recurrence. It will be an optimal choice for patients with primary malignant, aggressive benign, or solitary metastatic bone tumors of the thoracolumbar spine with Tomita surgical classification type 3 to 5.
OBJECTIVE: To observe the strength of thigh muscles after reconstruction of anterior cruciate ligament by autogenous bone-patellar tendon-bone graft. METHODS: Twenty-three patients, 9 males and 14 females, were followed up one year after reconstruction of the anterior cruciate ligament with autogenous bone-patellar tendon-bone graft. Through arthroscope, no intra-articular derangement was found. The strengths of isometric and isotonic contractions of the quadri ceps and the hamstrings muscles of the affected and contralateral thighs were recorded. RESULTS: The donor side for autogenous bone-patellar tendon-bone graft showed significant decrease (P lt; 0.01), but no effect on that of the hamstrings muscle(P gt; 0.05). CONCLUSION: To reconstruct the anterior cruciate ligament, harvest of the bone-patellar tendon-bone graft as a reparative material may markedly lower the strength of the quadriceps femoris muscle.
OBJECTIVE: To report repair and reconstruction of massively damaged wound under unusual condition. METHODS: One hundred and forty-seven patients with deep tissue defects were admitted from January 1993 to December 2000, among them, 96 cases suffered from electrical injury, 18 cases with hot press injury, 18 cases with deep burns as a result of CO poisoning or epileptic seizure, 6 cases caused by chemical producing necrosis and wound infection, 3 cases with radiation injuries, 2 cases with chemical burn, 2 cases with explosive injury, 2 cases with frostbite. One hundred and seventy five wounds in 147 patients were repaired by transfer of local flap, forearm conversal island skin flap, pectoralis major myocutaneous flap, delto-pectoral skin flap, latissimus dorsi skin flap, gastroecnemius myocutaneous flap, anterior and posterior tibial artery island skin flap, and so on. The wound defect ranged from 1 cm x 1 cm to 20 cm x 28 cm, and the flaps were 1.5 cm x 2.0 cm to 22 cm x 30 cm. The necrotic tendon was replaced with acellular allogenic tendon simultaneously in 7 cases. RESULTS: One hundred and sixty-nine flaps were survival with first intention, while necrosis of the tip of flap occurred in 6 cases. The transplantation of acellular allogenic tendon in all cases were survival. The function and configuration in 28 cases were satisfactory after 4 months to 8 years follow-up. CONCLUSION: Various types of flaps are choosen according to the position, defect range and degree of wound, which is an ideal method to restore the function and to improve patients’ living condition.
The clinical experience of rest-oration of apposition function in 75cases of 83 hands, since 1960, wasreported. Thirty-eight cases had beenfollowed-up with an averege time 8. 5years. The excellent recovery ratewas 65. 5% . The indication of vari-ous restoration methods. choose ofthe acting muscle, reconstructionof the trochlea. the supplementaryoperation and the rehabitation methodswere discussed. The author notedthat the most applicable muscleswere flexor digitorum superficialis,extensor carpi ulnaris and flexor carpi ulnaris, with the musele power ber than 4 degree. The trochlea must be stble and a distance from the tendon inserticn.
For the reconstruction of lacrimal passage in obligue facial cleft, three methods were performed in 4 cases. According to the difference in local pathology canaliculorhinestomy, transfer of vein or oral mucosa, or modified dacryocystorhinostomy was performed. The patients were followed for 6 to 12 months with satisfacting results.
Reconstruction and repair of atresia or defect of the upper portion of esophagus is difficult. From November 1980 to December 1997, forth-five cases, consisting 35 males and 10 females, were treated with microsurgical technique. The 45 patients fell into the following groups as esophageal atresia of various causes in 21 cases, anastomotic fistula or stenosis following reconstruction of esophagus in 7 cases and late carcinoma of esophagus in 17 cases. The types of reconstruction consisted of transfer of free jejunum with its lower portion carrying a vascular pedicle in 24 cases, free transfer of jejunal graft in 15 cases, free vascularized jejunal graft in 2 cases and free vascularized tubular skin graft in 4 cases. After a follow-up of 6-19 months besides eight cases died from late esophageal carcinoma, thirty-seven cases were survived and could take food by mouth. All of the benign cases could return to work. In patients having late esophageal carcinoma, the operative procedure could improve the life quality and facilitate chemotherapy and radiotherapy.
Objective To investigate the clinicalvalue of modified Weaver-Dunn technique in repair of acute acromioclavicular dislocation. Methods From January 1993 to December 1998, 18 cases of acromioclavicular dislocation were treated bymodified Weaver-Dunn technique, and other 17 cases of the same suffering were treated by tension band fixation of the acromioclavicular joints. All of the patients were followed up for 12-36 months before clinical evaluation of the functionof shoulder joints, according to University of Pennsylvanian Shoulder Score System. Results In short term, the shoulder joints recovered much more rapidly in the cases repaired by modified Weaver-Dunn technique; 12, 24 and 36 months after operation, the scores of the cases repaired by modified Weaver-Dunn technique were (1897±67), (193.7±3.6) and (194.7±3.4) respectively according to the Shoulder Score System, while those of the cases treated by tension band fixation were (167.3±7.8), (170.2±6.3) and (165.6±5.9) respectively. The above data indicated that there was significant difference between two groups (P＜0.05). Conclusion The modified Weaver-Dunn technique was a better surgical approach than tension band fixation for repair of acute acromioclavicular dislocation.
In order to solve the difficult problems of repair and reconstruction for severe deep burns with compound tissue defects of upper limb, 26 cases were treated with transplantation of compound tissue flap, vascularized by anastomosis of blood vessel or by vascular pedicle. Several kinds of reparative and reconstructive procedure could be performed simultaneously. Not only the tissue defect was repaired, but also the upper limb function was reconstructed in one stage operation. Owing to the presence of abundant vascular supply from the vascularized compound tissue and primarily closing the wounds, the anti-infection potency was high, then it was suitable for such conditions as fresh severe deep burn with infection and compound tissue defects. As a result, this technique provided the best chance to save upper limb from amputation. The duration required for treatment could be markedly shortened. All the cases successed. The long-term functional recovery was satisfactory. This method provided the possibility to solve effectively the difficult problem dealing with the severe deep burns with compound tissue defects of upper limb.
