The radiological and clinical results were analyzed according the number of screws and their position. Materials and Methods: Of 31 cases with an unstable pelvis fracture involving the sacral complex, classified as Tile type C (AO/OTA), 16 and 15 cases were treated with one S1 screw fixation and two screws fixation into S1 and S2, respectively, using a percutaneous fixation technique. The patients were followed up for a minimum of 12 months and the radiological and clinical outcomes were analyzed statistically using the Majeed score and SF-36. Results: Five cases of screw displacement occurred in the one screw fixation group. On the other hand, there was no screw displacement in the two screws fixation group after a mean follow-up of 40.2 months. In the case of a narrow safe zone (iliac cortical density, ICD), it is impossible to fix with two S1 screws. However, in these patients, good clinical results were achieved with S1 and S2 were achieved with S1 and S2 screw without complications. Conclusion: The technique of two screws fixation is an efficient and reliable method for reducing and fixing the unstable pelvic ring disruptions. Additional S2 screw fixation is recommended for patients with a narrow ICD.

Mowed 와 Geer 15) 에의하면제 1 천추의경우형태의변이가있는경우나사못의삽입이어려울수있고그러할경우제 2 천추에나사못을삽입하는방법이유용하다고하였고, 이에대한임상적안정성과효과에대해논한바있다. 본저자의경우에서도제 1 천추의안전영역이좁아두개의나사못을삽입하기어려운경우추가나사못을제 2 천추에삽입하였고신경손상의합병증은발생하지않았다. 제 2 천추의경우신경손상의위험이높기때문에술자의세심하고숙련된술기와충분한술전준비가필요하나본임상연구에서그결과는좋은것으로보아충분히가능한방법이라사료된다. 저자들의연구에서는일부의예에서동반손상이있는경우골반환의전방부의고정방법과이에대한고정력의차이가후방고정에미치는영향을고려하지않았기에부족한점이있으나이는추가적인비교분석이필요할것으로사료된다. 여러문헌의보고및본저자의경우와같이후방불안정성을가진골반환의골절에있어서는보다더안정적인내고정이필요하며경피적나사못을이용한내고정술을시행할경우두개이상의나사못고정으로내구성을높여주어야할것으로사료된다. 결론후방불안정성을가진골반환의손상에서제 1 천추에하나의나사못을사용한경우고정력이불충분할수있기에 1 천추나제 2 천추에추가적인나사못을이용해고정력을높이는것이좋을것으로여겨지며, 안전영역이좁은불안정골반환손상시에는제2 천추에서의추가삽입도권장될수있을것으로생각된다. 참고문헌 1.

J Trauma, 53: 44-48, = 국문초록 = 목적 : 불안정성골반골절에서천장관절의해부학적정복후 S1 혹은 S2 에천장골나사못을이용한고정술을시행한뒤나사못의위치와수에따른방사선학적및임상적결과를분석하였다. 대상및방법 : 천장관절골절및탈구를포함한 Tile 분류 C (AO/OTA) 의불안정성골반골절 31 예중 16 예에서는 S1 에한개의나사못을, 15 예에서는 S1 와 S2 에두개의나사못을이용한경피적고정술을시행하고, 평균 40.2 개월의추시관찰을하여방사선학적결과와 Majeed score 와 SF-36 을이용한임상적결과를분석하였다. 결과 : 수술후평균 40.2 개월 (12 76 개월 ) 관찰상 S1 에단한개의나사못으로고정한군중 5 예에서나사못의변위가있었으나두개의나사못으로고정한군에서는변위가관찰되지않았다. 경피적나사못고정술시좁은안전영역을보이는경우 S1 에두개의나사못으로고정하기어려운경우가있다. 본저자는좁은안전영역을가진불안정성골반환손상환자에게 S1 과 S2 에나사못을고정하여임상적으로좋은결과를보였다. 결론 : 불안정성골반환의정복과고정을위한두개의나사못을이용한경피적고정술은효과적이고믿을만한방법이며, 특히좁은안전영역을가진환자에게는 S1 에삽입후 S2 에추가로나사못의삽입이권장된다. 색인단어 : 불안정성골반골절, 경피적나사못고정술, 나사못의수와위치
