查询词典 Fracture

objective:to study and analyze the features of lower limb fatigue fracture in the special force by means of radiodiag-nosis.methods:anterior-posterior and lateral films and clinical follow-ups were made to all the affected limbs in the56cases of lower limb fatigue fracture from june2003to feb.2006.results:through medical history and radiodiagnosis all the cases were giv-en definite diagnosis,achieved good treatment results and all had clinical follow-ups.the average length of clinical follow-ups was3months.following treatment,all patients returned to work and resumed training.conclusion:lower limb fatigue fracture finds a rather high incidence in the special force.special features could be seen in the x-ray film,which has obvious clinical significance in the differential diagnosis of other diseases.

摘要］ 目的：分析特种部队下肢疲劳骨折的x线特征性表现和鉴别诊断。方法：从2003年6月～2006年2月，对56例来院就诊治疗的下肢疲劳骨折的患者全部进行患肢x线正侧位片检查和随访。结果：本组病例依据病史和x线分析，均明确诊断，经治疗后效果好，全部获得随访，平均随访时间3个月；骨愈合时间1～2个月，全部恢复工作和训练。结论：下肢疲劳骨折在特种部队发病率高，x线片中具有特征性表现，与其他疾病的鉴别具有重要的临床意义。

The increased risk of refracture persisted for up to 10 years after the index fracture and fractures of all sites, except the ribs in men and in ankle in women, increased the repeat fracture risk. Hip and vertebral fractures carried especially high risks of repeat fracture.

原部位再骨折风险性在原骨折10年内一直较高，几乎所有部位的骨折除了男性肋骨和女性脚踝部位外发生再骨折几率都比较高，尤其是股骨和椎骨骨折发生再骨折居高。

The indication for proximal femoral replacement was a periprosthetic fracture in twenty patients, reimplantation because of a deep infection in thirteen, a failed arthroplasty in thirteen, nonunion of an intertrochanteric fracture in one, and radiation-induced osteonecrosis with a subtrochanteric fracture in one. Three patients died before the minimum two-year follow-up interval had elapsed, and two additional patients were lost to follow-up.

进行股骨近端置换的适应证是假体周围骨折28例，由于深部感染而进行再次手术13例，关节置换术失败13例，股骨粗隆间骨折不愈合1例，放射线诱导的骨坏死并伴有股骨粗隆下骨折1例。3例患者在达到最短两年随访之前就去世了，另外还有两例患者失访。

Methods Mouse models of tibia fracture healing were established, and callus samples were collected 1, 3, 7, 14, 21 and 28 days after fracture. The development of callus and new bone formation were evaluated with roentgenology, Micro-CT and tetracycline double labeling method, and the expression of HIF-1α, vascular endothelial growth factor, Runx2 and ALP in callus were detected with RT-PCR, Western blotting and immunohistochemistry. The relationship between HIF-1α and fracture healing was analysed.
