目的：探讨后路环椎管减压，椎弓根钉系统复位固定并植骨治疗胸腰椎爆裂骨折的疗效。方法：1996－2001年，环椎环椎管减压，结合具有钉杆角的椎弓根钉系统复位固定，并横突及小关节突间植骨或椎间植骨治疗128例病人，从伤椎椎体前后缘高度恢复，Cobb角矫正度及神经功能恢复情况评价疗效。结果：128例病人脊髓神经损害无加重，神经功能有不同程度恢复；伤椎高度恢复理想，Cobb角明显减少，植骨融合成功108例（占84．4％），术后部分病例出现伤椎复位度丢失现象。结论：后路环椎管减压内固定治疗胸腰椎骨折效果好，应重视植骨融合以获得良好稳定性。     

Risedronate Reduces the Risk of First Vertebral Fracture in Osteoporotic Women

Risedronate treatment reduces the risk of vertebral fracture in women with existing vertebral fractures, but its efficacy in prevention of the first vertebral fracture in women with osteoporosis but without vertebral fractures has not been determined. We examined the risk of first vertebral fracture in postmenopausal women who were enrolled in four placebo-controlled clinical trials of risedronate and who had low lumbar spine bone mineral density (BMD) (mean T-score =–3.3) and no vertebral fractures at baseline. Subjects received risedronate 5 mg (n= 328) or placebo (n= 312) daily for up to 3 years; all subjects were given calcium (1000 mg daily), as well as vitamin D supplementation (up to 500 IU daily) if baseline serum 25-hydroxyvitamin D levels were low. The incidence of first vertebral fracture was 9.4% in the women treated with placebo and 2.6% in those treated with risedronate 5 mg (risk reduction of 75%, 95% confidence interval 37% to 90%; P= 0.002). The number of patients who would need to be treated to prevent one new vertebral fracture is 15. When subjects were stratified by age, similar significant reductions were observed in patients with a mean age of 64 years (risk reduction of 70%, 95% CI 8% to 90%; P= 0.030) and in those with a mean age of 76 years (risk reduction of 80%, 95% CI 7% to 96%; P= 0.024). Risedronate treatment therefore significantly reduces the risk of first vertebral fracture in postmenopausal women with osteoporosis, with a similar magnitude of effect early and late after the menopause.

肱骨近端移位骨折的手术治疗

目的：总结肱骨近端移位骨折的手术治疗方法和疗效。方法：分析手术治疗肱骨近端骨折28例资料。患者平均年龄24．4岁，平均随访2年6个月；手术均采用三角肌胸大肌间隙入路，钢板固定15例，交叉克氏针固定11例，单纯螺丝钉固定15例；采用Neer分类及评分方法评价手术结果。结果：两部分外科颈骨折优良率为64．7％，无头坏死及不愈合，三部分骨折和四部分骨折切开复位的满意率较低。结论：两部分骨折和三部分骨折可采用切开复位内固定，但尽量避免使用钢板；对四部分骨折，内固定满意率较低且肱骨头坏死率较高。     

锁骨钩钢板内固定配合康复治疗锁骨远端骨折

目的探讨和分析应用锁骨钩钢板内固定配合康复治疗锁骨远端骨折的新方法。方法42例应用锁骨钩钢板配合术后早期康复治疗锁骨远端骨折的患者全部得到了随访,随访时间2～46个月(平均15.6个月),患者年龄36～57岁,平均45.6岁。术后2d患肩按照制定的康复训练方法进行功能训练,最终随访按Lazzcano评价标准〔1〕评价治疗结果。结果42例患者术后X线检查均达到满意复位与固定,局部Lazzcano功能评定关节功能恢复优良率97.6%。结论应用锁骨钩钢板治疗锁骨远端骨折手术操作简单,配合术后完善的康复治疗,可得到非常满意的结果。     

膝关节镜下膝后侧腔室联合手术入路的探讨

[目的]探讨在关节镜下膝关节后侧腔室联合手术入路的重要性和可操作性。[方法]经过前内侧、前外侧和股骨髁切迹以及后内侧、后外侧和后纵隔内切口联合入路分别入镜、入器械，进行膝关节后侧腔室的探查和手术操作。[结果]216例（239膝）应用联合入路探查和治疗，其中5例膝因关节僵硬操作失败；175例膝用于治疗后侧腔室疾病，膝关节后侧腔室手术视野显著改善，探查和手术操作完善，均达到手术目的。1例膝内侧隐神经不全损伤，没有腘后神经、腓总神经、腘后血管、交叉韧带等重要组织损伤。[结论]膝关节后侧腔室病变较多，是检查和治疗的重要部位，并非“技术盲区”。这种联合手术入路，手术风险低，具备可操作性，可以提高手术效率和质量，可作为膝关节镜下常规手术入路。     

Results of non-operative treatment following hip fracture compared to surgical intervention

We followed all consecutive hip fracture patients admitted between 2004 and 2006, identified cases in which the intention was to treat non-operative and compared their functional outcome and mortality with a similar cohort treated surgically over the same period. We recorded length of hospital stay, place of discharge, pre and post-fracture mobility and residence, 30 days and 1 year mortality, re-admission due to same fracture and delayed surgery. The group treated surgically was recruited and matched for age, gender, pre and post-fracture mobility, mental confusion and independence. 25 patients were treated non-operative. 22 patients treated surgically over the same time period matched the patient characteristics of the non-operative arm. The mean hospital stay was 13 days in both groups. There were 4 extra-capsular fractures (3 displaced) and 21 intra-capsular fractures (5 displaced) in the non-operative arm and 11 extra-capsular fractures and 9 intra-capsular fractures in the surgically treated arm. 4 patients from the non-operative treatment group underwent late surgery because of persisting hip pain 20 days-2 months after the index event (2 cannulated screws, 1 hemiarthroplasty, 1 total hip arthroplasty). 11 patients in the surgical treatment arm underwent dynamic screw fixation, 1 had cannulated screw, 1 had total hip replacement and 7 had hemiarthroplasty. 14 of the non-operative treated patients were mobile independently or with aid before fracture but only 9 patients retained their pre-fracture mobility following treatment, compared to 16 patients pre-fracture and 11 patients post-fracture after surgery. 16 patients treated non-operative were living independently prior to injury but only 7 went back to their own residence. Of the operatively treated patients 14 patients were living independently and 10 patients went back to their previous residence. 1 month and 1 year mortality in the non-operative treated group was 4/21 and 7/21 respectively compared to 1/20 and 5/20 in the operative fixation group. There was no statistically significant difference in mobility, residence or mortality between the two groups (Fisher exact test, p > 0.05). Non-operative management after hip fracture is suitable for medically unfit patients and does not result in statistically significant difference in functional outcome or mortality compared to patients treated surgically.

踝关节骨折腓骨钢板的后方固定

目的：探讨踝关节骨折中腓骨钢板固定的位置。方法：2001年1月～2003年1月共手术治疗踝关节骨折患者75例，仅对其中随访资料完整的48例患者进行分析。随访10～24个月，平均15个月。采用Baird和Jackson的踝关节评分系统评定踝关节术后疗效。结果：所有的患者均取得了良好的骨折愈合。术后疗效为优24例，良17例，可5例，差2例。优良率为85、4％。结论：腓骨钢板的后方放置可以减少缝合时的张力，钢板有更好的软组织覆盖，钢板无须过多塑形，固定比较牢固。     

Specific selection of osteosynthetic material in the treatment of thoracic or lumbar spinal injuries by the posterior approach

Summary The authors report 165 cases of thoraco-lumbar lesions with neurological dysfunction. All the patient were operated. They analyze the neurological and mechanical results and indicate the use of different osteosynthesis apparatus according to the type and level of lesions.Harrington's rods seem to give more precise repositioning while Roy Camille's plates give more stability. When the posterior wall of the spinal canal is intact, Kempf's compression rods can be used.Thoraxic spine injuries seem to be an indication for Harrington's rods, while lumbar injuries seem to call for Camille's plates.
