Materials and Methods: We retrospectively reviewed patients with clavicle shaft fractures, who underwent surgery by using a locking plate between May 2011 and August The inclusion criteria were: 1) displaced 20 mm, 2) acute fracture of less than 2 weeks from injury, 3) skeletally mature patients, and 4) follow-up of at least 6 months. The demographic data and clinical outcomes, including operation time, fracture union rate, union time, shortening of clavicle, shoulder functional score (University of California at Los Angeles score), and complications, were evaluated. The clavicle length ratio was measured to evaluate shortening. We compared the clinical outcomes between two groups: the COP group that included 21 patients treated with COP (group 1) and the MIPO group that included 19 patients treated with MIPO (group 2). Results: In all cases, union of fractures was successfully achieved. The mean union time was 14.9 weeks in group 1 and 14.2 weeks in group 2 (p=0.713). Both groups had good functional scores (34.0 vs. 33.7, p=0.658). Group 2 had shorter operation time and less bleeding. There were no secondary interventions or infections. The clavicle length ratio was similar between the two groups; and all patients in both groups showed no shortening (less than 3%). There were no implant failures in either group. Conclusion: The clinical and radiologic outcomes were satisfactory in both groups. We suggest that MIPO may be a safe and effective method for displaced clavicle shaft fractures.

6 534 Jin-Young Bang, et al. 고정술 (2군) 은관혈적정복및금속판내고정술 (1군) 과비교하였을때기능및유합기간에있어서동등한결과를보였고두방법모두기능에서도우수한결과를나타냈다. 최근쇄골간부에서보존적치료와금속판고정술을비교하는전향적연구에서금속판고정술이보존적치료에비해견관절의기능향상에도움이되고부정유합혹은불유합의빈도를낮춘다고하였다. 4,10) 이번연구에서도두방법모두우수한결과를보여금속판고정술의장점을뒷받침하는근거가될것이다. 쇄골간부골절에대한수술적방법중에서금속정을사용한내고정술은수술반흔의길이를줄이고연부조직손상을줄일수있다는장점이있다. 하지만금속정파손, 금속정의내측또는외측이동, 쇄골단축등의문제점을보였다. 19) 이번연구에서금속판을사용한고정한두방법모두쇄골단축은보이지않았으며, 최소침습적금속판고정술방법은수술반흔의길이를줄이고골절부위절개로인한추가적인연부조직손상을피할수있는특징이있다. 따라서최소침습적금속판내고정술은쇄골단축에있어서최소침습적내고정술중의하나인금속정내고정술의문제점을보완할수있을것으로생각한다. 최소침습적수술의장점이될수있는수술중출혈량은최소침습적금속판내고정술을시행한 2군에서적게나타났는데이는피부절개의최소화와연부조직박리및골막박리가관혈적정복에비해적게이루어졌기때문인것으로보인다. 최소침습적금속판내고정술의 2군에서수술소요시간이관혈적정복및금속판내고정술의 1군에비해짧은것으로나타났다. 하지만이번연구에서술자는두명으로한명은최소침습적및고식적금속판고정수술모두를, 나머지한명은고식적금속판고정술을시행하였으므로술자에따른차이의잠재적인오류를고려해야할것이다. 최소침습적금속판고정술술기에익숙해진경우연부조직박리및봉합에대한시간이줄어듦으로써전체수술시간의단축이가능할것으로해석할수도있을것이다. 한편본연구에서최소침습적금속판고정술을시도하였으나골편이근육사이에포착 (entrapment) 되어관혈적정복술로전환한경우가 1 예있었으며, 이는최소침습적도수정복이실패한경우에무리하게수술을진행하기보다는관혈적정복술로수술방법을전환하는치료전략의유연성이필요함을보여준다. 이번연구에서방사선노출시간, 급성기통증은비교하지못하였다는제한점이있는데, 방사선노출정도는최소침습적금속판내고정술의단점으로꼽히는데이에대한비교가없어아쉽다. 최소침습적수술일경우방사선조사를더많이하게되므로수술시이에대한주의와보호장치의착용이중요할것이다. 20) 쇄골의최소침습적금속판고정술에서급성기통증이상대적으로적을것이라는가설은이번연구가후향적연구라는점에서확인할수가없었다. 지금까지쇄골간부에서관혈적정복및금속판고정술과최소 침습적금속판고정술의비교연구는두건이발표되었고, 모두후향적연구이다. 21,22) 수술후임상기능에서는두방법모두우수한결과를보였다는공통된연구결과가있었고, 한연구에서는최소침습적금속판고정술에서골유합이빠르다고하였다. 21) 두연구모두수술시간에는차이가없다고하였고, 출혈량에대한결과는없었다. 이번연구의결과와함께정리하여본다면임상적기능은고식적금속판고정술과유사하에우수한결과를보이고, 골유합기간은고식적금속판에서와비슷하거나빠르다고할수있다. 이연구는한계점으로는후향적디자인의적은수의비교연구라는데있으며, 쇄골간부의골절치료시최소침습적금속판고정술의임상결과를정립화하기위해서는향후전향적연구및대규모환자군을통한검증이필요할것이다. 또한최소침습적금속판고정술에서기대할수있는적은절개길이및흉터에대한만족도에대한자료는추후연구를통한검증이필요할것이다. 두번째로는골유합기간을평가하기에는 4주간의방사선촬영간격으로인한정확한평가가이루어지지않았다는오류의가능성이있으나현실적으로더자주촬영하기에는어려움이있음을감안하여야할것이다. 결론 이번연구결과는전이성쇄골간부골절에서최소침습적금속판고정술과고식적방법인관혈적정복술및내고정술은모두기능및방사선적으로모두우수함을보였다. 따라서최소침습적금속판고정술은전이성쇄골골절의수술적치료법으로유용한한가지방법이될것이다.
