技術說明:

下肢骨折是骨科臨床實務最常處理的骨折之一。主要的治療方式是利用骨髓內鋼釘和微創互鎖式骨板固定骨折。雖然骨釘/骨板技術已臻成熟,遠端的固定螺釘對許多骨科醫師來說仍是場惡夢。利用透視X光機找尋「完美圓孔」的徒手技巧仍是最常被採用的定位方式。這種方式的缺點包括較長的手術時間和輻射曝露,還有螺釘錯置的可能性。輻射曝露會帶來後續細胞和染色體的傷害,更有可能增加骨科醫師罹癌的機會。過長的手術時間亦可能增加感染及其他併發症的機率。我們的研究目標是希望提供一個快速、安全以及準確的螺釘定位方式。採用光電工程以減少手術過程對醫師及病人的輻射曝露。

Low extremity long bone fractures are among the most common fractures encountered in orthopedic practice. Intramedullary interlocking nailing and minimal invasive locking plating are considered as the current treatment methods for the management of lower limb long bone fractures. Although the technique of tibial and femoral antegrade nailing or plating have been well-established, the placement of distal locking screws is still troublesome for many orthopedic surgeons. Free-hand technique of attaining "perfect-circles" with the assistance of fluoroscopy is most common method for the insertion of distal locking screw. Its pitfalls include increased operative time, increased radiation exposure, and the incidence of distal locking screw misplacement. The aim of our study is to provide orthopedic surgeons with a fast, safe, and precise targeting device for screw placement by using electro-optical engineering to decreased radiation exposure of fluoroscopy to both the surgeons and the patients.
