Objective To study the clinical results of early surgery for acute cervical spinal cord injury. Methods 24 cases of acute cervical spinal cord injury were treated with early surgery in our hospital from 1999 to 2002. The average interval from injury to surgery was 67 hours. The injured cervical segments were reduced, decompressed and fixed through anterior approach, posterior approach or anterior posterior approach. Results 22 cases got follow ups of 12 to 38 months (mean 18 months), but 2 cases were lost. 2 cases of the 11 patients of ASIA Grade A did not experience any restoration, but all the other patients got significant restoration and an average improvement of 1.8 ASIA grades. Conclusion Operation should be performed as soon as possible for acute cervical spinal cord injury, for good results can be achieved by early surgery.

Objective To compare the efficacy of low temperature controlled plasma technology by nasal endoscopy and cystectomy via labiogingival groove approach in treatment of nasal vestibular cyst. Methods 38 patients with nasal vestibular cyst from Jan 2013 to Nov 2016 were selected and randomly divided into control group (n = 20) and observation group (n = 18). The control group received cystectomy via labiogingival groove approach and the observation group received low temperature controlled plasma technology by nasal endoscopy. The time of surgery, bleeding volume in surgery, hospitalization, postoperative complications and relapse were collected and compared between the two groups. Results We found that the observation group have less surgery time than that in control group [(65.45 ± 27.51) vs (34.72 ± 17.61) min, P = 0.000], less bleeding volume in surgery [(22.35 ± 18.41) vs (3.17 ± 1.69) ml, P = 0.000), less postoperative complications [(6.35 ± 0.75) vs (3.61 ± 1.19) d, P = 0.000] and less postoperative complications (16 vs 1, P = 0.000), but relapse of the two groups have no statistical difference (1 vs 0, P = 0.783). Conclusions Low temperature controlled plasma technology by nasal endoscopy in treatment of nasal vestibular cyst have many advantages than cystectomy via labiogingival groove approach such as shorter time of surgery, less bleeding volume in surgery, shorter hospitalization and less postoperative complications. Therefore it's worth of applying clinically.

Objective To evaluate endovascular treatment of Budd-Chiari syndrome(BCS)with occlusion of hepatic veins.Methods Retrospective analysis on the clinical materials of 32 BCS cases with occlusion of hepatic veins was made.Four cases received inferior vena cava(IVC)angioplasty or stent implant and splenorenal shunt;Transfemoral vein or transjugular hepatic vein angioplasty was performed in 10 cases,and percutaneous transhepatic recanalization combined with transjugular and/or transfemoral vein angioplasty of hepatic veins was performed in 16 cases,respectively.Two cases failed therapy attempt.Results A failure to find the main hepatic vein in percutaneous transhepatic venography lead to the abandent of therapy in 2 cases.Hepatic vein angioplasty and IVC angioplasty was successful in the other 30 cases.The pressure of hepatic vein decreased from(43±8)cm H_2O to(16±4)cm H_2O(t=21.23,P<0.01).The symptoms were obviously relieved,ascites disappeared,abdominal distension palliated,chest and abdominal wall varicose veins collapsed one week after endovascular treatment.During perioperative procedure,2 cases with liver puncture bleeding were cured by laparotomy.The follow-up duration was 5 months to 65 months and mean(26.0±2.0)months.There was no stent migration and hepatic vein restenosis and occlusion.Chest and abdominal wall varicose veins disappeared and esophagus phlebeurysma were ameliorated as shown by esophageal barium series.There were no pulmonary embolism and death.Conclusions The procedure of endovascular treatment of BCS with occlusion of hepatic veins is simple,mini-traumatic and effective.

ObjectiveTo compare the outcomes and indications between exchange nailing (EN) and augmentation plating (AP) with a nail left in situ for femoral shaft hypertrophic nonunion after femoral nailing. MethodsFrom April 1998 to June 2009, 20 patients with femoral shaft hypertrophic nonunions after femoral nailing were treated with EN (11 patients) and AP (9 patients) respectively. There were no significant differences between the two groups with respect to the patient's age, gender, associated injuries, anatomical location and type of femoral fracture. Patients were evaluated by imaging and clinical function at 1, 2, 3, 4,6, and 12 months after surgery, and then every year postoperatively, to observe the callus and the recovery condition of the affected limb function. Fisher exact test and t'-test were performed to compare the outcome and complications respectively. ResultsAn unpaired t'-test showed no significant differences with respect to follow-up time, operating time, intraoperative blood loss, postoperative drainage, length of stay, time to radiographic union, time to clinical union, and AAOS score between the two groups. The cost of hospitalizations in the EN group was higher than in the AP group(t'=16.4, P=0.013). Four nonunions in the EN group failed to achieve union, which 3 patients were subsequently treated with AP and simultaneous autogenous bone grafting and 1 patient was treated with nail dynamization. All 9 hypertrophic nonunions in the AP group obtained osseous union. Fisher exact test showed a higher nonunion rate of EN compared with AP (χ2=6.01 ,P=0.008). ConclusionEN has been an excellent choice for aseptic isthmal femoral nonunion without a large bone defect subsequent to intramedullary fracture fixation, and AP can be an effective solution in cases of nonisthmal femoral nonunion and bone defect and failed exchange nailing.

Objective To investigate the operative indications and operation techniques for augmentative plate fixation in treatment of femoral shaft atrophic nonunions subsequent to intramedullary fixation. Methods Twelve femoral nonunions after internal fixation with intramedullary nailing were treated with augmentative plate internal fixation and bone graft from June 1999 to June 2008. All femoral nonunions were caused by insecure fixation of the intramedullary nailing, in which a rotational instability of the fracture site was verified in all the patients during operation. Minimally invasive removal of the granulation tissue at fracture site and the sclerotic bone was dccorticated. The adequate lilac bone was tiled longitudinally on the nonunion gap and the cortical bone bed. The fixation involved the limited-contact dynamic titanium plate with 5-6 holes, 3.0 mm Kirschner wire and 4-6 double cortex cortical screw fixation.Protective weight-bearing was given after surgery and the tunction was evaluated at 1,3, 6 and 12 months with imaging. Results All patients were followed up for 7-26 months ( average 17.4 months), which showed radiological solid union (7-12 months, average 9.4 months) and clinical union (5-9 months, average 7.1 months ). The operation lasted for 50-120 minutes ( average 77.5 minutes), with blood volume of 150-350 ml ( average 252 ml). There were nine patients with bone pain, of whom the pain was relieved within one month in seven patients and three months in two. No infection, hardware loosening or breaking were found. Conclusion The plate augmentation and cancellous bone grafting leaving the nail in situ can be an effective solution for nonisthmal femoral nonunion, bone defect and failed exchange nailing.
