ABSTRACT
BACKGROUND: With an aging population increasing, the incidence of senile femoral intertrochanteric fractures is on a rise because of osteoporosis. Due to the aged usually accompanied with systematic diseases, conservative treatment will lead to high mortality after long-term bedridden. Thereafter, early surgery is recommended. OBJECTIVE: To investigate the incidence of femoral intertrochanteric fractures and its epidemiological features. METHODS: The digital radiography data and basic information of 179 patients (over 50 years of age) with femoral intertrochanteric fractures admitted in the General Hospital of Tianjin Medical University from 2013 to 2015 were analyzed retrospectively. The data including age, gender, injury causes, fracture types, complications, treatment procedures, and hospitalization time were recorded and compared. RESULTS AND CONCLUSION: All the 179 cases of femoral intertrochanteric fractures were enrolled, including 66 (36.9%) males and 113 (63.1%) females. The mean age was (76.98±9.73) years, and the number of patients aged 80-90 years was the most (n=71, 39.7%). With the age increasing, the incidence of fall-induced hip fractures was increased. By AO classification, type 31-A1 was the most common fracture type (46.4%), and type 31-A3 was the least common type (22.9%). By Evans classification, type I was the most common type (50.3%), and type V was the least common type (2.2%). There were 93.3% patients underwent surgical treatment (167/179), and 6.7% received conservative treatment (12/179). In the age group of 51-60 years, the male patients were more than females; in the age group 61-70 years, the male patients were more than females except in 2013; in the age groups of 71-80, and 81-90 years, the female patients were more than males; in the age group of over 90 years, there was no significant difference between female and male patients. These results manifest that the majority of hip fracture patients are the elderly, and slipping and osteoporosis are the leading causes. In spite of accumulating operative risks with aging, surgical treatment remains the predominant management strategy. Besides, the incidence of femoral intertrochanteric fractures shows a trend of increase yearly, with the highest incidence in the age group of 71-90 years, especially in females.
ABSTRACT
The incidence of multiple noncontiguous spinal injuries (MNSI) in the cervical spine is rare but has catastrophic consequences. The patient in this report was a 34-year-old woman with five-level cervical MNSI. CT and MRI showed that injuries included atlantoaxial instability, burst fracture of C6, dislocation of C6/7, rupture of the intervertebal disc or ligamentous complex, and irreversible cord damage. The mechanism for this case was a combined pattern of hyperflexion, compression, and hyperextension injuries. A review of the literature revealed that this case is the first report in the literature of a vehicle related accident causing five-level noncontiguous injuries of the cervical spine.

<p><b>OBJECTIVE</b>The purpose of this study is to investigate the osteogenic potential and possibility of combination application of mimetic osteoinductive periosteum with tissue-engineered bone.</p><p><b>METHODS</b>The three-dimensional construction of tissue-engineered bone was made by implantation of adipose derived stromal cells (ADSCs) into rhBMP-2 mediated bio-derived carrier, and mimetic periosteum was constructed by loading ADSCs into Cs-Col-beta3-TCP with rhBMP-2. 10 mm defects of right radiuses were established in adult New Zealand rabbits, group A was transplanted by tissue-engineered bone with mimetic periosteum, group B was implanted by tissue-engineered bone, and group C was implanted by mimetic periosteum, group D was transplanted by bio-derived compound bone as blank scaffold. X-ray, histology, immunohistochemistry stain, dural energy X-ray absorptiometry (DEXA) and transmission electron microscopy (TEM) examinations were performed at different periods.</p><p><b>RESULTS</b>Group A played a predominant role in process of new tissue regeneration and mature bone reconstitution, defect completely healed at 12 weeks. Group B showed primary repair, group C also existed in modeling stage. While, group D displayed retard regeneration with poor osteogenic capacity. DEXA result showed that group A had statistical significance over control group according to data of BMC and BMD ( P < 0.05).</p><p><b>CONCLUSIONS</b>Enhanced osteogenic potential can be obtained by using tissue-engineered bone with mimetic osteoinductive periosteum. Defect can be healed with concord pattern of osteoinductive and osteopromotive and osteoconductive effects.</p>
