复位

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。

METHODS: Twenty-two patients with lower condylar fractures and four with mandibular ramus fractures were treated with transparotid approach for open reduction and internal fixation.

Final reattachment was achieved in all 61 eyes (100%).

全部61例(100%)得到最终的复位。

Results All cases had got retinal reattachment, and their postoperative vision improved in different level.

结果 全组32眼术后视网膜脱离均成功的复位，术后视力有不同程度的提高。

Proliferative vitreoretinopathy, or PVR, is the main cause of failure of retinal reattachment surgery.

增殖性玻璃体视网膜病变即PVR，是导致视网膜脱离复位手术失败的主要原因。

Objective: To study the possible histomorphological change of undetached retina after retinal reattachment.

目的：研究视网膜脱离复位后未发生脱离区域的视网膜组织形态改变。

Best-corrected visual acuity was 20/40 or better in 25 of 61 study eyes (41%). Primary retinal reattachment was attained in 60 study eyes (98%).

最佳矫正视敏度是20/40或者61例中25例(41%)较好。60例(98%)获得一期视网膜复位。

Objective To study possible mechanism of retinal functional recovery and ultrastructure changes of retina after retinal reattachment.

近年来视网膜脱离（retinal detachment，RD）的手术治愈率有了很大的提高，然而手术的最终目的不仅仅是为了达到解剖复位，更重要的是功能上的恢复。

The visual acuity of 25 cases was increased and 11 eyes (91.7%) retina reattachment after follow-up period for 3 to 10 months.

术后随访观察3~10个月，31只眼中25只眼视力不同程度提高，11(91.7%)眼视网膜复位。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
