1 ORIGINAL ARTICLE Print ISSN Online ISSN Traumatic Dislocation of the Hip with a Femoral Head Fracture Yerl-Bo Sung, MD, PhD, Jung-Yun Choi, MD, Jong-Woo Kim, MD Department of Orthopedic Surgery, Sang-Gye Paik Hospital, College of Medicine, Inje University, Seoul, Korea Purpose: This study was designed in order to evaluate the clinical results and frequency of complications of patients who underwent surgical treatment for traumatic dislocation of the hip with a femoral head fracture. Materials and Methods: Eighteen cases of Thompson-Epstein type V femoral head fracture with dislocation of the hip from November 2002 to November 2011 were analyzed retrospectively. We divided the cases into two groups according to availability of closed reduction and reduction time, and analyzed the clinical results according to Epstein criteria and frequency of avascular necrosis of the femoral head and posttraumatic osteoarthritis. Results: Among all patients, the observed complications included three cases of avascular necrosis and one case of posttraumatic osteoarthritis. The data showed that 14 cases were available for closed reduction; otherwise, there were four cases of failure. Significant differences were observed in clinical results and frequency of complications. Results regarding reduction time showed that 10 cases took 6 hours, and the other eight cases took more than 6 hours. There were no differences in clinical results, but, better results were achieved with a reduction time in 6 hours. However, significant differences were observed in frequency of complications. Conclusion: The availability of closed reduction would be an important factor for achievement of good clinical results in traumatic dislocation of the hip with a femoral head fracture. In order to obtain better clinical results, closed reduction should be performed as rapidly as possible.

Pipkin I 형의경우 2 예에서는관절경을이용한골편제거술을시행하여우수의임상적결과를얻었다. 나사못고정술을시행한 2 예중 1 예에서는우수의임상적결과를얻었고 (Fig. 1), 척추손상과편측대퇴경부골절이동반된 1 예에서는양호의임상적결과를얻었으나수상후 3 개월만에침상낙상으로인공고관절반치환술을시행하였다. Pipkin II 형의경우 2 예에서모두나사못고정술을시행하여양호의임상적결과를얻었다. Pipkin IV 형의경우 2 예에서는후벽비구골절에대해서나사못고정술을시행하였고, 10 예에서는금속판고정을시행하여 6 예에서양호이상의임상적결과를얻었으며, 나머지 6 예에서보통이하의임상적결과를얻었다. 양호이상 6 예중 1 예에서는좌골신경손상이동반되었으며 12 개월추시관찰결과회복되었고, 비구에대해서금속판고정술을시행한후 2 개월후에재탈구가인지되어수상당시손상된연부조직으로인해전치환술을시행하면반복적인재탈구가우려되어반치환술을시행하고외래에서추시관찰중이다 (Fig. 2). 보 통이하 6 예중 1 예에서외상성관절염과 3 예에서대퇴골두의무혈성괴사가인지되어불량의임상적결과를얻었으며인공고관절치환술을시행하였다 (Table 4, Fig. 3). 고 찰 본연구는대퇴골두골절을동반한외상성탈구에서도수정복가능여부및정복까지걸린시간에따른임상결과및합병증발생빈도사이의연관성을알아보고자하였고, 도수정복이가능하며정복까지걸린시간이 6 시간이내로빠를수록임상결과가좋아지는경향을알수있었다. 또한, 조기에도수정복이실패한경우전체합병증발생빈도가높아진다는결과를얻었다. 고관절탈구의도수정복방법으로 Canale 6) 은 Stimson 6,8) 방법, Allis 6,7) 방법, Bigelow 6) 방법이있다고하였으며, 본연구에서는 Stimson 방법과 Allis 방법을이용하였다. Lyddon 등 10) 과 Gittins 등 11) 은고관절후방탈구에서정복시단외회전근, 비구골편, 손상된비구연등에의해방해된다고하였으며, 본연구에서는 4 예에서비구골편에의해도수정복이실패하였다. Pipkin 5) 은 Thompson-Epstein 4) 분류 V 형의후방탈구 A B C D E F G Fig. 2.

6 및골절을다시대퇴골두골절양상에따라 4 가지형태로분류하였으며 Stannard 등 12), Marchetti 등 13) 은 Pipkin IV 형이제일많다고보고하였으며, 본연구에서도 IV 형이 12 예로제일많이발생하였다. Stannard 등 12) 은도수정복을최대한빠르게하고골절편을해부학적으로정복및정확한고정이좋은결과를얻을수있다고하였고, 24 시간을기준으로조기에정복하는경우가더좋은결과를보인다고보고하였으나, Marchetti 등 13) 은도수정복을 6 시간기준으로비교분석한결과유의한차이점을얻지못하였다고보고하였다. 본연구에서는 24 시간이내에는대부분도수정복이이루어져서 6 시간을기준으로하여 6 시간이내가 10 예, 이후가 8 예있었으며임상결과를비교분석한결과역시유의한차이점을얻지못하였으나 6 시간이내로조기에정복을시행하면임상결과가좋아지는경향을알수있어추후더많은대상자를통한연구가필요할것으로사료된다. Epstein 등 15) 은고관절의후방탈구시발생하는합병증으로대퇴골두의무혈성괴사이외에관절연골, 관절낭, 인대등의손상으로외상성관절염이나, 좌골신경손상, 관절주위의이소성골화등을보고하였고, Pape 등 16) 은 손상초기에적극적으로치료하는것이합병증발생률을감소시켜좋은결과를얻을수있다고하였다. 국내연구를살펴보면 Kim 등 17) 은 10 예의대퇴골두골절에대해평균 33 개월간추시관찰하여 1 예의외상성관절염과 1 예의대퇴골두의무혈성괴사를보고하였으며, Park 등 18) 은 17 예의대퇴골두골절에대해 4 예의대퇴골두의무혈성괴사와 1 예의이소성골화증의합병증을보고하였다. 대퇴골두의무혈성괴사는자기공명영상촬영을통해서진단하고 Marchetti 등 13) 과 Kloen 등 19) 은 6% 에서 23% 까지보고하고있으며수상후 17 개월째에서 2 년까지잘발생한다고하였는데 1), 본연구에서도수상후추시 2 년동안에 3 예 (16.7%) 발생하여인공고관절치환술을시행하였다. Hougaard 등 20) 은대퇴골두의무혈성괴사의위험성이대퇴탈구로부터정복까지걸린시간이 6 시간이상지연될경우발생위험도가증가한다고하였으며, 본연구에서도 6 시간을기준으로전체합병증발생빈도에는유의한상관관계가있었으나대퇴골두의무혈성괴사의발생빈도는유의한차이를발견할수없었다. 외상성관절염에대해 Watson-Jones 14) 은수상당시손상정도및대퇴골두의체중부하부위에따라발생률을결 A B C D E F Fig. 3.

7 Yerl-Bo Sung et al.: Traumatic Dislocation of the Hip with a Femoral Head Fracture 정하는데단순대퇴골두탈구보다는대퇴골두골절이동반된탈구시발생률이높다고보고하였으며발생빈도는 0% 에서 72% 까지보고가되고있고 13,20), Epstein 등 15) 은조기에관혈적정복술을시행하여관절내골절편을제거하고비구골절편을내고정하여안정성을유지하면외상성관절염의발생률을줄일수있다고하였다. 본연구에서추시 1 년후에 1 예 (5.6%) 발생하여인공고관절치환술을시 행하였다. 본연구의제한점은후향적연구로드물게발생하는대퇴골두골절이지만증례의수가적고 Pipkin III 형에대해서는연구가이루어지지않았으며, 수술방법의차이에따른예후등임상결과에영향을미치는다양한인자에대해파악하는데에도제한이있었다.

8 결 론 처음내원시도수정복이가능한경우가임상결과가양호하였고도수정복이실패할수록대퇴골두무혈성괴사등의합병증발생빈도가높은경향을보였으며, 보다나은임상결과를얻기위해서는수상후가능한한빠른시간안에정복을시행해야할것으로사료된다. REFERENCES 01. Brumback RJ, Kenzora JE, Levitt LE, Burgess AR, Poka A.
