他文献 タニケットしたら術後早期の体内での出血、腫脹が強くなり、SLR(下肢挙上)・膝の屈曲も有意差に下がる Li B, Wen Y, Wu H, Qian Q, Lin X, Zhao H. The effect of tourniquet use on hidden blood loss in total knee arthroplasty. Int Orthop. 2009 Oct;33(5):1263-8. doi: 10.1007/s00264-008-0647-3. Epub 2008 Aug 27. PMID: 18751703; PMCID: PMC2899119.
システマティックレビュー 術中出血はタニケットしたほうが少ないが、総出血量は変わらず 輸血量も変わらず術後合併症発生率はタニケット使用したほうが多くなる Smith TO, Hing CB. Is a tourniquet beneficial in total knee replacement surgery? A meta-analysis and systematic review. Knee. 2010 Mar;17(2):141-7. doi: 10.1016/j.knee.2009.06.007. Epub 2009 Jul 19. PMID: 19616954.
両側同時TKA タニケット使用vsしない 28例ずつ 術後3ヵ月はタニケット使用したほうが四頭筋回復遅い ハムストリング筋力は変わらない やはり総出血量は差がない Dennis DA, Kittelson AJ, Yang CC, Miner TM, Kim RH, Stevens-Lapsley JE. Does Tourniquet Use in TKA Affect Recovery of Lower Extremity Strength and Function? A Randomized Trial. Clin Orthop Relat Res. 2016 Jan;474(1):69-77. doi: 10.1007/s11999-015-4393-8.

●液体の成分は? 単純性骨嚢胞なら血清成分 COHEN J. Simple bone cysts. Studies of cyst fluid in six cases with a theory of pathogenesis. J Bone Joint Surg Am. 1960 Jun;42-A:609-16. PMID: 13849417.
●鑑別?→手術の際に病理検体とるのは必須 線維性骨異形成症:皮質骨が繊維組織に置換される病
動脈瘤性骨嚢腫:貯留液体が血液
骨巨細胞腫:破骨細胞様の巨細胞が増殖する骨腫瘍 悪性腫瘍ではないが骨破壊性強い
●Fallen fragment signとは? CT画像で骨嚢胞内に骨片を認める所見
●骨片かどうかの見極め方は? MRIでT1 high T2 high STIR(脂肪抑制)で低信号なら骨片と考える
以下単純性骨嚢胞に対する掻爬+人工骨移植+Ender釘加療の報告 ●対象37例(上腕骨19,大腿骨12,脛骨2,尺骨1) 平均年齢11.7歳 ●方法 上腕骨:術後2~4週から自動運動開始 下肢:術後4~6週から荷重開始 ●結果 全例癒合(術後平均8週) 感染、再骨折、抜去なし 4例変形癒合 Erol B, Onay T, Çalışkan E, Aydemir AN, Topkar OM. Treatment of pathological fractures due to simple bone cysts by extended curettage grafting and intramedullary decompression.

また病的骨折なしならドレナージだけでも治癒率は91.7%ほど(引用文献より)
