【はじめに】大腿骨転子部骨折におけるfemoral short nailでは,tip-to-apex distance(TAD)を20mm以下にすることでカットアウト率が減少すると言われている.本研究の目的はTADを術中測定できるcomputer-assisted navigation system(Navi)の有用性を検討することである.【対象と方法】大腿骨転子部骨折40例を対象とし,Navi群20例,非Navi群20例を比較した.評価項目はTAD,手術時間とした.【結果】TADはNavi群13.4mm,非Navi群15.2mm(p=0.18)であった.TADが10mmから20mmである症例はNavi群95%,非Navi群75%であった.手術時間はNavi群36.9分,非Navi群37.4分(p=0.90)であった.【考察】TADに2群間で有意差は認めなかったが,Navi群の方がより正確な位置に挿入することが可能であった.また手術時間に両群間で有意差はなかった.【結語】Femoral short nailにおけるNaviは有用である可能性が示唆された.

There are rarely few reports on the clavicular motion during elevation of the extremity. This is may due to the complicated shape of the clavicle and its three-dimensional movement. The purpose of this study is to analyze the movements of clavicle by using X-ray fluoroscope.The study was performed on a 21 years old female who had clavicular fracture a year ago and had fixation with plate and screws. She had no difference on both shoulder ROM when examined. In front of X-ray fluoroscope, she was asked to abduct her arm to full in 10 seconds, and the movements were recorded on videotape. From the location of plate and screws we analyzed the clavicular motion.The clavicle rotated clockwise in its long axis when viewing from the left sagittal plane. This movement increased constantly during the elevation of arm and reached 50 degrees at maximum abduction. In Frontal view, 25 degrees of upward movement was observed, where the majority of the movement was seen within 90 degrees of elevation.
