4 0 0 0 非接触型膝前十字靱帯損傷の下肢前額面アライメント
目的:非接触型前十字靱帯(anterior cruciate ligament:ACL)損傷の骨解剖学的リスク因子を抽出することである. 対象と方法:初回非接触型ACL損傷患者33例33膝(ACL群)と健常者26例26膝(対照群)の下肢荷重位X線像から下肢前額面アライメントと骨形態を計測した. 結果:ACL群では対照群よりも静的下肢アライメントが外反しており,脛骨近位内側角と大腿骨遠位外側角が影響していた. まとめ:荷重位下肢アライメントが外反するほど膝関節への外反トルクが強くなるため,ACLに応力が集中して靱帯損傷に至る危険性が高くなると考えられる.

Objective: The present study aimed to determine the generation and behavior of airborne particles that could carry microorganisms around the area of the feet while walking in a bio-clean operating room.Methods: Four surgical staff members performed four walking patterns comprising combinations of the following: independently or as a group, and entering or exiting the operating room.Results: Fine particle visualization and laser particle counts revealed large numbers of airborne particles on shoes, the hems of gowns, and the floor regardless of the walking pattern. Numerous airborne particles were generated by followers who walked in groups and even more particles were brought to the level of the operating table by groups compared to solitary walkers.Conclusion: Surgical staff should be aware of transferring airborne particles from non-sterile areas to reduce the incidence of contamination by airborne bacteria in bio-clean rooms.
