Methods The clinical data of 43 adult patients (59 sides)suffering from chronic sinusitis with frontal sinus involved were analyzed retrospectively. The frontal sinus ostium was identified by the help of artificial frontal drill (20 cases) or XPS frontal drill (23 cases), and the efficacy was evaluated via postoperative follow-up of all cases. Results The ostia of frontal sinus were successfully opened in all cases, and no serious complications occurred.

METHODS: The 15 hybrid dogs were randomly divided into 2 groups. In the experimental group (n=9), a hole was drilled at the slope beneath the tibial plateau to reach the medullary cavity. The cavity was enlarged by an appropriate drill to confirm the size of the cavity. The absorbable polyamide intramedullary rods were inserted from the hole in tibial superior extremity, and the fracture was anatomically reduced with the rod passing through the fracture. Two locking nails, which were cylinder polyamide rods, were respectively located 2 cm from the cutting site, in the distal and proximal ends. Auxiliary plaster external fixation was performed for 4 weeks. In the control group (n=6), quincunx intramedullary nails of the same diameter with 4 pre-drilled holes were accordingly inserted into the cutting segment, and 2 screws were locked in the distal and proximal ends, respectively.

15只杂种犬随机分为2组，实验组(n=9)：在距离胫骨平台下斜坡处钻孔入髓腔，用合适钻头扩大髓腔，确认髓腔大小，从胫骨上端开孔插入聚酰胺钉，解剖复位骨折端并使该钉通过骨折处，在距离截骨处2 cm处的远近端分别锁上2枚锁钉，锁钉为圆柱形聚酰胺棒，辅助石膏外固定4周；对照组(n=6)：同样插入相应直径的、已预钻4孔的梅花形髓内钉截段，在骨折端的近端及远端分别锁2枚螺钉，辅助石膏外固定4周。

New Zealand white rabbits (3-4 months old, 3-4 kg weight) were the test animals, and they were divided into three groups proceeding in this study. In group A:One PLLA screw and one commercial screw were implanted in the right tibia. Two PLLA screws were implanted in the left. Furthermore, one PLLA bar was implanted in both right and left tibia respectively with onlay model in group B. Also,one PLLA plate was implanted in the left tibia and one commercial plate in the right respectively with onlay model in group C . Many tests were done on each sample in 1, 4, 8 and 12 weeks which included the observation of tissue response in group A, and the change of three-points bending, weight loss, molecular weight, crystallinity and morphology of fracture surface by scanning electronic microscopyin group B, and the change of three-points bending, weight loss and molecular weight in group C.

所使用实验动物为24只3-4个月大，体重3-4公斤的纽西兰兔，并将所使用材料及动物分为A、B、C三组进行。A组中於实验兔之右胫骨植入两支骨钉，一支为自制骨钉，一支为MacroPore市售骨钉，并钻一孔但不植入骨钉做为控制组；另於实验兔之左胫骨植入两支自制骨钉，另标示一区不钻孔不植入骨钉做为控制组。B组采用onlay1 模式於实验兔之左右胫骨各植入一自制长型片。C组也采用onlay模式於实验兔之左胫骨植入一自制骨板，於右胫骨植入一市售骨板，各於不同时间点( 1， 4及12周)将A及C组，而於( 1，4，8及12周)将B组内的植入物取出进行各种测试，包括A组的组织切片观察及B组的三点弯曲变化、质量损失、分子量变化、结晶度变化及扫描式电子显微镜观察断面型态改变及C组的三点弯曲变化、质量损失、分子量变化。
