We report a retrospective study to compare the outcome after ESWT (group l, 15 cases) with the effect of medication treatment (group 2, 15 cases) in patients with chronic calcific tendinitis. Patients were aged 42 to 58 years, mean of 48 years and treated with extracorporeal shock waves or medication from September 2012 to May 2014. The ESWT was performed six cycles of shock waves, weekly treatment for the three cycles and the rest cycles after 2 weeks of pause. In the same period, there were 12 women and 3 men treated with medication treatment for calcific tendinitis. The clinical outcomes were evaluated according to Constant and Murley score and pain visual analogue scale. Radiologic evaluation was performed to confirm disintegration of calcific deposits 3 months and 6 months after treatment. Clinical outcomes were significantly improved in ESWT group, and there was significant difference between ESWT group and medication group. In radiographic evaluation, the calcific deposit was significantly decreased in ESWT group. ESWT therapy is more effective to achieve functional improvement and to alleviate pain in the patients with calcific tendinitis of the shoulder.

VAS는동통을주관적인평가에기초하여나타내며통증이없는경우를 0점으로하고극심한통증을 10점으로정하였고, 치료전과치료이후 6개월에조사하였다. 방사선학적치료평가를위하여치료전과치료후 3개월및 6개월에단순방사선촬영을시행하여석회화결절의크기를확인하였다. 통계적검증은 SPSS ver.17.0 (SPSS Inc., Chicago, IL, USA) 를이용하였다. Demographic factor는 Mann- Whitney test로, 치료전후결과는 paired t-test를이용하여 p-value<0.05인변수는유의한차이가있는것으로분석하였다. 결과 CMS 점수는체외충격파치료를시행한제1군에서치료전평균 26점에서치료후평균 72점 ( 범위, 47 92점 ) 으로증가하였고약물치료를시행한제2군에서는치료전평균 29점에서치료후평균 45점 ( 범위, 23 78점 ) 으로호전되어체외충격파치료를시행한경우더월등한견관절기능의회복을보였 다. VAS 점수도두군에서모두감소하였으나제1군에서치료전평균 8.8점 ( 범위, 6 10점 ) 에서치료후평균 2.3점 ( 범위, 0 5점 ) 으로감소하였고제2군에서는치료전평균 8.3점 ( 범위, 5 10점 ) 에서치료후평균 5.2점 ( 범위, 2 10점 ) 으로체외충격파치료시행시더나은통증의감소를보였다. 이는모두통계학적으로유의하였다 (Table 2). 방사선학적평가에서제2군에서는총 15명의환자중약물치료 3개월뒤 3명, 6개월뒤 7명이방사선촬영에서석회화결절의감소가관찰된것에비해제1군에서는총 15명중체외충격파치료 3개월뒤 7명, 6개월뒤 13명에서석회화결절의감소가관찰되었다. 체외충격파치료시방사선학적석회화결절의감소도더뚜렷한것으로나타났다 (Fig. 2). 체외충격파치료이후건파열이나골부종과같은심각한임상적부작용은없었다.

YT Lee, et al. The Effect of Extracorporeal Shock Wave Therapy for Calcific Tendinitis of the Shoulder 고찰석회화건염은퇴행성이아닌반응성석회화과정으로석회침착의형성과용해의진행에따라석회화전기, 석회화기, 석회화후기로구분한다 2,3,7). 통증이나운동제한등의증상은주로석회화기에서발생하는것으로알려져있다. 견관절통증은팔을거의움직일수없을정도로극심할수있으며야간에악화되는양상을보인다. 석회침착은수년이지나면저절로흡수되어사라지게된다. Gartner와 Simons 14) 는견관절방사선에서경계가뚜렷한석회침착이 3년뒤 33% 에서자발적으로사라졌음을보고하였으며, Bosworth 1) 는석회침착의 6.4% 가자발적인용해과정을거쳤음을보고하였다. 본연구에서는석회화건염환자에게체외충격파요법을시행한군에서약물치료를시행한군보다증상의완화와기능의개선이더월등하며, 석회화침착의소실도더많은것으로나타났다. 그동안의증례보고, 코호트연구및임상실험을포함한다양한보고에서도석회화건염환자에있어체외충격파요법이좋은치료결과를보고하였다 15). 수술적치료에비해서도체외충격파요법은비침습적이고안정성이보장되어있어더효과적인치료로알려져있다 16). 이연구역시이러한경향을뒷받침한다. 체외충격파쇄석술 (extracorporeal shock wave therapy) 은 1980년부터요석제거목적으로임상에서사용되었고최근에는비뇨기과영역에서요석치료의가장많이이용되고있다. 90년대초반부터체외충격파쇄석술은골절의불유합, 족저근막염과외측상과염등의만성건염에대한치료에되었다 17-19). Loew 등 20) 은견관절의석회화병변에체외충격파치료의효과에대해기술한바있으며, 이후에도다양한보고가이루어졌다 16,21). 체외충격파치료의성공률은 30% 에서 85% 로다양하게보고되며, 각각의경우마다다른횟수, 용량, 시술방법으로시행되기때문에결과에대해논란이많다 22,23). 체외충격파요법의효과에대한정확한생체내기전은알려져있지않다. 신생혈관생성, 조직의재분화, 과잉자극에따른마비효과가조직회복에중요한역할을한다고알려져있으며 7,14), 체외충격파는직접적으로조직자극을통해분자수준에서이러한반응을유도한다는가설도제기되고있다 24). 또한체외충격파는인접점액낭으로의석회침착물의흡수를촉진시키며국소염증반응을통해침착물의파괴를돕는다고알려져있다 25,26). 체외충격파요법을시행한후국소발적이나피하혈종의 발생등의부작용이보고된바있다 27). 또한고에너지의충격파를조사하였을경우시술중통증을호소하는경우가있으며이러한통증감소를위해시술전국소마취를시행하는경우도있다. 그러나그동안체외충격파요법에의해건파열이나골부종과같은심각한임상적부작용이발생되었다는보고는없다. 본연구에서도이러한부작용은발생하지않았다. 본연구의제한점은후향적연구로진행되었으며, 체외충격파의용량에따른차이를분석하지않은점이다. 또한석회성건염의자연사로인해증상이호전된것인지, 체외충격파나약물치료로인해증상이호전된것인지명확하지않다. 그렇지만저용량의체외충격파치료로도, 초음파를통해정확한부위에시행을할경우에석회화건염의치료에효과적임을알수있다. 견관절석회화건염에있어체외충격파치료는약물치료보다더유의미한관절기능의향상과통증의감소및방사선학적소견의호전을보인다.
