ObjectiveTo compare the short-term effectiveness of one-stage posterior debridement with non-structural bone graft and structural bone graft in the treatment of single segment thoracic tuberculosis.MethodsThe data of 61 patients with single segment thoracic tuberculosis, who were treated by one-stage posterior debridement, bone graft fusion, and internal fixation between June 2011 and August 2015, was retrospectively analyzed. All of them, 26 cases were treated with structural bone graft (group A) and 35 cases with non-structural bone graft (group B). No significant difference was found between the two groups in gender, age, disease duration, comorbidity, involved segments, paravertebral abscess, and preoperative American Spinal Injury Association (ASIA) grade, C reactive protein (CRP), visual analogue scale (VAS) score, and Cobb angle of involved segments (P>0.05). But the preoperative erythrocyte sedimentation rate (ESR) in group B was significantly lower than that in group A (t=3.128, P=0.003). The operation time, intraoperative blood loss, hospitalization stay, VAS score, ESR, CRP, ASIA grade, postoperative complications, Cobb angle of involved segments and its correction rate and loss rate, and bone fusion time were recorded and compared between the two groups.ResultsCompared with group A, group B had shorter operation time, less intraoperative blood loss, and longer hospitalization stay, showing significant differences (P<0.05). The follow-up time of group A was (36.3±10.0) months, which was significantly longer than that of group B [(18.4±4.2) months] (t=10.722, P=0.000). At last follow-up, the VAS score, ESR, and CRP in the two groups all significantly improved when compared with those before operation (P<0.05); the CRP of group B was significantly higher than that of group A (t=–2.947, P=0.005); but there was no significant difference in ESR and VAS score between the two groups (P>0.05). At last follow-up, the ASIA grade of the two groups significantly improved when compared with those before operation, and there was no significant difference between the two groups (Z=–1.104, P=0.270). There were 9 cases and 10 cases of complications in groups A and B, respectively, and there was no significant difference (χ2=0.254, P=0.614). The Cobb angle in group B was significantly higher than that in group A at 3 days after operation (t=–2.861, P=0.006), but there was no significant difference in Cobb angle between the two groups at last follow-up (t=–1.212, P=0.230). The postoperative correction rate and loss rate of Cobb angle in group A were higher than those in group B, and there was a significant difference in the loss rate between the two groups (t=2.261, P=0.031). All patients got bone graft fusion and the bone fusion time of group B was significantly shorter than that of group A (t=4.824, P=0.000).ConclusionNon-structural and structural bone graft can both achieve good effectiveness in the treatment of single segment thoracic tuberculosis, but the former has the advantages of less surgical trauma and shorter fusion time.
【摘要】 目的 总结复杂胫骨平台骨折手术治疗的临床经验。 方法 2007年1月-2009年12月,采用切开复位内固定治疗复杂胫骨平台骨折56例。男37例,女19例;年龄19~76岁,平均45.6岁。骨折按Schatzker分型:Ⅳ型12例,Ⅴ型26例,Ⅵ型18例。合并半月板损伤20例,膝内侧副韧带损伤9例,外侧副韧带损伤8例,交叉韧带损伤4例。受伤至手术时间7~14 d,平均9 d。 结果 术后53例切口Ⅰ期愈合;2例术后3 d切口出现浅表感染,1例术后7 d外侧切口出现皮肤坏死、钢板外露,均对症处理后愈合。56例均获随访,随访时间14~49个月,平均19个月。骨折均于术后4~8周愈合,平均6周。并发膝关节僵硬1例、创伤性关节炎2例、异位骨化1例,相应处理后治愈。术后12个月按美国特种外科医院评分标准评价疗效,获优43例,良5例,可4例,差4例,优良率85.7%。 结论 手术治疗复杂胫骨平台骨折需重视软组织条件,掌握好手术时机、选择合适内固定、提高手术技巧、术后有效的功能锻炼是保证疗效的关键。【Abstract】 Objective To summarize the clinical experiences of surgical treatment for complex tibial plateau fractures. Methods From January 2007 to December 2009, 56 patients with complex tibial plateau fractures underwent open reduction and internal fixation. The patients included 37 males and 19 females with the age of 19-76 years old (average 45.6 years old). The Schatzker type of the fractures were type Ⅳ in 12 patients, type Ⅴ in 26, and type Ⅵ in 18. The injuries included meniscus injury in 20 patients, injury of lateral collateral ligament of knee in 9, injury of lateral collateral ligament in 8, and cruciate ligaments injury in 4. The time duration between the injury and the surgery was 7-14 days (average 9 days). Results After the surgery, the incision healed at I stage in 53 patients. The incision was superficially infected 3 days after surgery in 2 patients, and the Necrosis of skin around the incision and revealed steel plate were found 7 days after surgery in 1 patient; the injuries was healed after corresponding treatment. All of the patients were followed up with the average follow-up period of 14-49 months (average 19 months). The fractures healed 4-8 weeks (average 6 weeks) after the surgery. Knee joint ankylosis was found in one, traumatic arthritis was found in two, and heterotopic ossification was found in one; the injuries was healed after corresponding treatment. Twelve months after the surgery, the therapeutic effect according to HSS criteria indicated that the score was excellent in 43, good in 5, generally in 4 and poor in 4; with a fine rate of 85.7%. Conclusion Appropriate conditions of the soft tissue, good surgical opportunity, a appropriate fixation, improved surgical technique and effective postoperative functional training are the key points of surgical treatment for complex tibial plateau fractures.
ObjectiveTo explore the endothelial cells from human peripheral blood and islet of rat co-transplantation under the renal capsule of diabetic nude mice to improve the survival and function of transplanted islet. MethodsThe endothelial cells from human peripheral blood(5×105)and freshly isolated rat islet cells were co-transplanted under the renal capsule of diabetic nude mice model, then the fasting blood glucose, body weight, peripheral blood C-peptide level, and intraperitoneal glucose tolerance test(IPGTT) were measured to evaluated the islet graft survival and function. ResultsCompared with the control group, the fasting blood glucose level significantly decreased(P < 0.01), peripheral blood C-peptide level rised(P < 0.01), and body weight increased(P < 0.01) of receptor nude mice in experience group, the IPGTT also improved. ConclusionThe endothelial cells from human peripheral blood and islet of rat co-transplan-tation can obviously improve the survival and function of transplanted islet of nude mice.
