骨端

New bone formation was observed to be increasing significamly in both DCN bone cements and DC bone cements with the passage of time. By the end of 24 weeks, new bone had bridged the gap between the proximal and distal fragments in DCN bone cements and DC bone cements. By histomorphological detection in DCN bone cements, Abundant of chondral and new bone islands were seen at the site of defects 4 weeks after the operation and a number of new bones formed and enlarged by both enchondral ossification and appositional formation by the 8th weeks.

研究发现，DCN骨水泥植入4周大量间充质细胞分化，在材料与骨端之间出现一层软骨细胞，软骨细胞继续增生并向编织骨分化；8周材料降解的同时，小梁骨出现；12周新骨长入材料并已经基本替代完成，形成初步骨性连接；24周骨缺损完成骨性连接，新骨进行结构改建，材料内部形态结构明显变化。

Objective: To discuss the clinical effect of the treatment of metaphyseal cancellous bone fracture with fragment fixation system implants.

的：探讨骨片钉治疗骨端松质骨骨折的临床效果。

Result］the operation time was 1～3 h,the operative bleeding quantity were 150～400 ml,all incisions were obtained primary healing.twelve cases were followed up from 6 months to 8 years.the average extremity functional score according to the system of isols（international society of limb salvage）:upper extremity was 22.3 and the lower was 25.3 the average bone healing time of returned deactivation bone graft and bone allograft healing with the osteotomy plane was 3 months,original tumor recurrence in local was 1,the recurrence rate was 7.69%,no malignant change and metabasis was found.

结果］手术时间1～3 h，术中出血量150～400 ml，术后切口一期愈合。12例患者获6个月～8年随访。按isols评分标准评价肢体功能恢复情况：上肢平均22.3分，下肢平均25.3分。灭活回植骨、异体骨与截骨端平均3个月愈合，局部复发1例，复发率7.69%。无恶性变及全身转移。

Improved Simmonds procedure for treating serious abnormalty of hallux valgus can thoroughly correct the abnormality; do not affect the length of the metatarsus; contacting face of the bone cutting is bigger with good stability and simpler operation, do not need to plant the bone and can be applied to patients of the different ages.

改良Simmonds手术对治疗严重拇外翻畸形矫正效果好，不影响跖骨的长度，不需植骨，截骨端接触面积大，稳定性好，利于愈合，适用于不同年龄的严重拇外翻畸形。

The average osteotomed length from the tip of great trochanter to distal osteotomy site was 12.4 cm (9～15.1 cm).The osteotomy sites were healed in 11 patients at 3 months and 2 patients at 6 months after operation.

平均截骨长度从大粗隆顶点至截骨远端为12.4 cm(9～15.1 cm)。11例患者在术后3个月时截骨端愈合，2例患者在6个月随访时截骨端愈合。

Suitable operation combination, bone shaft lengthening nearing bone end, keeping endosteal cortical bone osteotomy, and a continual lengthening of 1.0 mm.d- for adults and 1.5～2.0 mm.d-1 for children can get ideal limb length, quality and fast callus development and satisfactory joint function.

实施靠近骨端的骨干延长，保留内骨膜的皮质骨截骨，成人每天1.0 mm、儿童每天1.5～2.0 mm的连续延长，可获得理想的肢体长度、良好的骨痂生长速度和质量以及满意的关节功能。

Similar expression of BMP-2, TGF-β,bFGF between the test groups and control groups was noted. Inflammatory cells in the hematoma expressed bFGF and proliferating periosteal cells, endosteal cells, medullary mesenchymal cells expressed TGF-β at 3 days postoperatively.

实验侧和对照侧3天时血肿中炎性细胞时即开始表达bFGF，增殖骨膜、骨内膜、骨髓间质细胞表达TGF-β。1周时骨端骨细胞、骨痂成骨细胞才开始表达BMP-2，同时也表达TGF-β。

Suitable operation combination, bone shaft lengthening nearing bone end, keeping endosteal cortical bone osteotomy, and a continual lengthening of 1.0 mm .

实施靠近骨端的骨干延长，保留内骨膜的皮质骨截骨，成人每天1.0 mm、儿童每天1.5～2.0 mm的连续延长，可获得理想的肢体长度、良好的骨痂生长速度和质量以及满意的关节功能。

Methods The fractures of the trochanteric part of the femur were reduced and then fixed with bone-end plate.

股骨粗隆间骨折复位后采用骨端钢板内固定，钢板骨端与骨折近。。。

Methods 21 cases with suspicioned avulsion fracture of articular portion of tubular bone were reviewed. The cortical continuity of separate small bone and contiguous bone portion was investigated. The swell of soft tissue around these small bones was observed simultaneously.

回顾性分析21例怀疑骨端骨折而行法医学鉴定的案例，通过观察骨端游离小骨周边是否存在连续的骨皮质、小骨片相对侧表面是否有连续的骨皮质和局部软组织肿胀情况，并结合损伤机理考察骨折形态。
