Pipkin 10) 은 Thompson-Epstein 분류 V 형의후방탈구및골절을다시대퇴골두골절양상에따라 4 가지형태로분류하였으며 Marchetti 등 9), Stannard 등 11) 찰 은이중 4 형이제일많다고하였으나, 저자의경우에는 1 형이 5 예, 4 형이 4 예순이었다. Stannard 등 11) 은조기의도수정복의시간및조기의안정화, 골절의해부학적정복과견고한고정등이좋은결과를획득하는데필수적이요소라고하였고조기정복술이 24 시간을경과하여정복한것보다더좋은결과를보인다고하여정복시간과예후와의연관성에대하여보고하고있다. 반면 Marchetti 등 9) 은대퇴탈구의정복을 6 시간이내와이후를비교분석하여결과상에유의한차이점은없었다고보고하고있다. 저자들도최대한빠른시간내에정확한해부학적정복을시행하기위하여노력하였으며타병원에서전원시에도정복후내원한경우가많아 9 예에서 6 시간이내에, 나머지 1 예에서도 12 시간이내에정복을시행할수있었다. 저자들은전례에서일차적으로도수정복술을시행하였으며 8 예에서는 llis 방법, 나머지 2 예에서 Stimpson 방법을통하여정복하였다. 정복을시행한후의정확성은관절면의간격이건측과 2 mm 이상의차이가있을때와 Shenton 씨선의파열로판단하여해부학적정복의실패 C D Fig. 2.

5 김정호 이상홍 문영래 김동휘 송근상 나관절면정복의일치성 (congruency) 을얻지못한경우, 관절내골편에의한유리체가존재하는경우등을대퇴골두골절의수술적치료의적응증으로판단하였다 11). 대퇴골두골절의치료에있어서관혈적정복술을시행할것인지골절편의제거술을시행해야할지에대해서는논란이있다. utler 2) 는대퇴골두골절편이특히중앙와하부 (caudal to fovea) 양상일때 1/3 정도까지는제거할것을주장하였다. Swiontkowski 등 12) 은 Pipkin I 형의골절에있어서해부학적인도수정복이이루어지지않았을경우에관혈적정복술후골절편에대한내고정술이필요하다고주장하였다. Greenwald 과 Haynes 7) 는큰골절편이중앙와상부 (cephalad to fovea) 로존재하는경우에는비구연골과관절면이접촉하는부위이며체중부하에관여하기때문에견고한고정술이필요하다는데에동의하고있다. rumback 등 1) 은내고정물로써 Countersunk O screw, Herbert screw, ioabsorbable pin 등을권장하였고이를통해좋은결과를보고하였다. 저자들의경우 Pipkin 1 형에서도수정복후안정성확보및골편의완전정복의경우에대부분보존적치료를시행하였으며불완전정복된 1 예에서 Herbert screw 를이용해양호한고정을얻을수있었다. 고에너지손상을받은젊은환자에있어서는가능한한내고정술을일차치료로서고려하여야 하나분쇄가심한대퇴골두골절및탈구에서나고령의환자에있어서는고관절반치환술이나전치환술은매우유용한치료방법이다 8). 이는수술시간이짧고, 대퇴골두무혈성괴사를피할수있으며, 조기에기능적재활을할수있다는장점이있다. 저자들의 3 형증례에서대퇴경부골절을동반하면서대퇴골두의심한분쇄골절을동반하여일차적인공관절전치환술을시행하였다. Pipkin 4 형의경우대부분의저자들은비구골절의정복및고정후대퇴골두정복및고정을시행하는것을주장하였는데저자들도 2 예에서는작은대퇴골두하부골절편은제거하고비구부는금속판내고정술및나사못삽입술, 비교적비구부후연의골절편이적어관절안정성이유지되고대퇴골두의정복이양호한 2 예에서보존적치료를시행하였는데총 4 예중경도의외상성관절염과자기공명영상에서골두하부작은골절편의무혈성괴사가각각 1 예씩발생하여가장예후가불량하였다. 또한수술적방법으로써 Epstein 등 3-6) 은전방도달법의사용시후방탈구시손상된혈액공급이재손상됨으로써후방도달법의유용성을제기하였는데저자들의경우에도전예에서후방도달법을이용하여수술적치료를시행하였다.

Materials and Methods: Ten cases of Thompson-Epstein type V femoral head fracture with a posterior dislocation of the hip were evaluated. ccording to the Pipkin classification, 5 cases were type I, 1 case was type III, and 4 cases were type IV. The average age at time of trauma was 38 (19~72) years, and the causes were traffic accidents in 9 cases and falls in 1 case. The average follow-up period was 33 (13~79) months. reduction of the fracture was performed within 6 hours in 9 cases and 12 hours in 1 case. When the stability was achieved after the reduction, the choice of further treatment was made from either conservative treatment while maintaining skeletal traction, or surgical treatment according to the fracture type and instability. The complications were evaluated by a physical examination, simple radiography, computed tomography (CT) and magnetic resonance imaging (MRI). Results: In Pipkin type I fractures, 4 cases were treated with conservative treatment and 1 case was treated with surgical treatment. One case of Pipkin type III fracture was treated with primary total hip arthroplasty. In Pipkin type IV fractures, 2 cases were treated surgically using a plate and 2 cases were treated with conservative treatment with skeletal traction. one union was achieved in all cases. One case of mild posttraumatic arthritis and 1 case of avascular necrosis was found, respectively in Pipkin type IV. Conclusion: The extent of the initial injury has an effect on the prognosis of a hip fracture and dislocation. Key Words: Femoral head fracture, Posterior dislocation of the hip, Pipkin type 182
