Purpose: The purpose of this study was to evaluate the clinical results of scaphoid nonunions treated with 1, 2-intercompartment supraretinacular artery (ICSRA) pedicled vascularized bone grafting (VBG) and headless compression screw fixation. Methods: Since August 1, 2005, 11 scaphoid nonunions with avascular necrosis or bone marrow edema of proximal fragments were managed with 1, 2-ICSRA pedicled VBG combined with headless compression screw fixation. The mean age was 37.1 years (range, years). 8 patients had avascular necrosis (AVN) of proximal fragments and 3 patients had bone marrow edema in proximal fragments. Serial radiographic evaluations were performed in every 4-8 weeks for bone union and follow up computed tomography scanning were checked in 8 patients. Results: Bone unions were obtained in all 11 patients at 4.9 months (range, 3-9 months) after operation. At last follow up, the average range of motion was 82.5% and the grip power was 84.1% compared to the contralateral side. The mean New York Orthopaedic Hospital wrist score at last follow up was 83.2 (range, ). Conclusion: Combined 1, 2-ICSRA pedicled VBG and headless compression screw fixation were reliable methods for managements of scaphoid nonunions even with AVN at proximal fragments.

5 Dong-Hyun Kim, et al. Scaphoid Nonunions Treated with 1, 2-ICSRA Pedicled Vascularized Bone Graft and Headless Compression Screw Fixation 합의빈도가높은데이는주상골의혈행분포나활액에의한골유합의방해와같은해부학적문제와, 장기간증세가없이지내는경우에있어진단및치료지연및인대의불안정성에기인한다고하였으며 1,2, 주상골의불유합시에는수근관절의불안정성으로인하여관절증 (arthrosis) 으로진행되거나주변인대관계에의해 humpback 변형이동반될수있어 3, 수술등의적극적인치료가필요하다고하였다 11. 주상골불유합의수술적치료에는불유합의정도에따라서여러가지방법들이사용되고있다. 지연유합을보일경우에는경피적핀고정술만을시행할수있고, 섬유성불유합 (Fibrous nonunion) 또는경화성병변 (Sclerotic nonunion) 이동반된불유합에서는적절한골이식과견고한내고정을시행할수있는데, 최근의연구결과에따르면비혈행성골이식과내고정을이용한주상골불유합의수술적치료후 47% 에서 100% 까지의유합률을보고하고있다 12. 주상골요부의 Humpback 변형이동반된경우에는수장측접근을통해서쐐기형골이식 (wedge bone graft) 를시행한경우에서좋은결과를보고하였다 13. 주상골근위극의불유합인경우에는혈행이유지된다면, 기존의골이식및내고정만을시행해도골유합을얻을수있지만, 무혈성괴사가동반된경우에서는골유합에실패할가능성이많다 14. Matti-Russe 골이식술의경우에서도, 여러문헌에서높은유합률이보고되어보편적으로사용되고있으나, 근위골편의골괴사가동반되었을경우유합률이낮다는단점이있다. Green 4 은수술중근위골편의혈행이확인될경우에유합률을 92% 라고보고하였으며, 근위골편의무혈성괴사를보인경우에서는불유합률이 100% 라고보고하였다. 유경혈관화골이식술은 1991년 Zaidemberg 등 7 이치료에성공적인결과를보고한후많이이용되는술식중하나로써, 근위골편의골괴사가동반되었을경우에다른술식에비해높은골유합률이보고되고있고, 골유합까지의기간이짧아정상생활로의복귀가빠른장점이있다 10,14. 유경혈관화골이식술은원위대퇴골이나장골에서시행하는방법도소개되어있는데 15, 신체의두부위를절개한다는점, 혈관의해부학적변이가있다는점에서제한점이있다. 원위요골부위 1, 2 구획간상지대동맥혈관경을이용한방법은이러한단점을보완하여가장보편적으로사용되는방법으로 Doi 등 16 과Boyer 등 17 은근위골편골괴사가있는주상골불유합에서유경혈관화골이식을시행한바 60%-100% 의유합률을보고하였다. 본연구에서는주상골의무혈성괴사가있는부분에대해서소파술을시행하고, 소파술후발생한골결손부위및낭종이있던부위에대해서는부분적으로자가장골이식술을시행하였으며, 무두압박나사못을이용하여내고정을시행한뒤에유경혈관 화골이식술을시행한바, 수술후 100% 의유합률을얻을수있었다. 수술중근위골편의점상출혈을확인하지않은것은본연구의한계라고할수있으나자기공명영상검사상의음영변화가지혈대를풀었을때근위골편의점상출혈을보이는수술소견과가장근접하므로 18 본연구에서는수술전자기공명영상검사소견과골소파술시의육안적소견을종합하여골괴사여부를판단하였다. 11예중 3예에서근위골편의무혈성괴사소견이아닌, 골부종소견을보였는데급성골절이아닌불유합에서보이는골절면에국한되지않은광범위한골부종은빈약한혈행과무혈성괴사로의진행을시사하는소견으로생각할수있으며 19, 생골이식술은골유합시기를앞당기고유합률을높이는데도움이될것으로판단되어나머지 8예와마찬가지로유경혈관화골이식술을시행하였다. 주상골불유합의골이식을통한수술적치료후골유합까지의기간에대해서는 Doi 등 16 이평균 12 주, Malizos 등 15 은 6-12 주, Park 등 13 은 10.7주로보고하였으나, 본연구에서는평균 4.9개월 ( 약 20주 ) 에유합을얻어조금더긴유합기간을보였다. 이러한결과는수술의적응증을좀더넓게적용하여, 주상골근위부무혈성괴사의비율이 11예중 8예로타병원의연구에비하여높았기때문이라생각된다. 주상골의내고정에있어서 K-강선과무두압박나사못을사용할수있는데, K-강선의경우에는고정력이불충불할수있고, 무두압박나사못의경우혈관경을손상시킬가능성이있으며골편의크기가작을경우고정에어려움이있다는단점이있다. 본연구에서는혈관경의손상이나이식골의파손을방지하기위하여전예에서먼저무두압박나사못을이용하여압박고정을시행하여불유합부위를확실하게안정시킨뒤유경혈관화이식골을감입시키는수술방법을통하여좋은결과를얻을수있었다. 주상골불유합의자연경과가대부분에있어각변형이나관절염을동반한다는것을고려할때, 불유합부위의재혈관화뿐만아니라골절부위의안정성또한중요한요소라생각하여무두압박나사못을이용하여압박고정을시행하였다. 근위골편의무혈성괴사와 humpback 변형이동반된 1예에서는유경혈관화골이식술과자가장골을이용한쐐기형골이식술을병행하였는데, 이는주상골의혈액공급을개선하여빠른골유합을촉진하는것도중요하지만, 환자의증상이불유합에의한증상보다는주상골모양의변형에의한것이므로, 혈행공급을개선함과동시에변형에대한교정술을시행한것이다. 유경혈관화이식골을쐐기모양으로넣는것을고려할수있으나이경우기술적으로어렵고, 혈관경이손상되면골유합을얻을수없을뿐아니라변형의교정역시 177

6 J Korean Soc Surg Hand Vol. 19, No. 4, December 2014 시간이지나며붕괴될가능성이높기때문에자가장골을이용하여추가적인쐐기골이식술을시행하였다. 수술후운동범위에대해서 Rajagopalan 등 12 은건측에비해굴곡 -신전각이 29%, 요-척굴곡각이 40% 정도감소한다고하였으나, 본연구에서는건측에비하여평균 17.5% 의감소를보여우수한결과를보였으며모든환자에서일상생활로의복귀가가능하였다. 본연구의대상이적고자가장골망상골이식술을병행하였기때문에전예에서골유합을얻을수있었던것이반드시유경혈관화골이식술때문이라말하기에는어려움이있지만근위골편의무혈성괴사를동반한불유합의경우에도전예에서골유합을얻어혈행장애를동반한주상골불유합에적용할수있는신뢰할만한술식으로판단된다. 결론 주상골의불유합에대하여 1, 2-구획간상지대동맥유경혈관화골이식술과병행한무두압박나사고정술은근위골편에무혈성괴사를동반한불유합의경우에도재혈관화를통한골유합과증상및수근관절의기능을호전시켜관절고정술혹은근위수근열절제술을대신하여선택할수있는유용한술식으로생각된다.
