Materials and Methods: We studied 29 cases of communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate from April 2009 to April 2013. Fracture was classified according to AO/OTA classification. Postoperative clinical evaluation was performed with measurement of wrist range of motion (ROM) at last follow-up, modified Mayo wrist scoring system (MMWS), and visual analogue pain scale (VAS). Radiologic evaluation was performed with measurement of radial length on immediate postoperation and last follow-up, radial inclination, volar tilt and ulnar variance checked at the last follow-up using Sarmiento criteria. Results: Using the MMWS, 13 cases were classified as good, 10 fair, and 5 normal. The average wrist ROM was 88.5% for flexion, 92.2% for extension, 90.5% for adduction, and 94.0% for abduction. The average VAS was 1.7. On the last follow-up, average radius length, radial inclination and volar tilt did not show statistically significant improvement (p>0.05) compared to immediate post operation measurements, and according to Sarmiento criteria, 5 cases were classified as good, 14 fair, and 7 normal. Conclusion: Treatment of severe communited distal radius fracture accompanied by bone defect with volar locking plate and allogenic cancellous bone graft is a satisfying and effective treatment method in the elderly.

Zhang 등 12) 은 26 명의원위요골의관절내분쇄골절환자를대상으로외고정장치를이용한수술적치료를시행하였고, 임상적및방사선적으로좋은결과를얻었다고보고하였다. 또한 Kofoed 13) 는분쇄골절과전위된관절내골절에서외고정장치및골시멘트를이용한보강을시행하였으며, 합병증없이양호한결과를보고하였다. 반면 Arora 와 Malik 14) 은외고정장치의축성신연력만으로는정상적인수근관절면의수장측경사를회복하기어렵고, 관절내골절편을충분히정복할수없을뿐아니라해면골의소실로인한정복소실이발생할수있음을보고하였으며, Mudgal 과 Jupiter 15) 는과신연으로인해수근부및수지의구축이올수있음을보고하였다. Na 등 16) 은후방분쇄및전위가있는경우후방금속판을이용한고정술로좋은결과를얻었다고보고하였다. 그러나후방접근법은신근지대의절개가필요하고, 신전건

Treatment of the Communited Distal Radius Fracture Using Volar Plate with Allogenic Bone Graft 13 의손상이발생하기쉬우며, 금속판의고정을위해리스터결절의절제가필요하다는단점을가지고있다. 여러저자들은불안정한원위요골골절에서수장측잠김금속판을이용하여내고정술을시행하여좋은결과를보고하였다. 또한수장측잠김금속판은신전건의손상이적고, 배측에비해연부조직이풍부하여내고정물이만져지는합병증이적으며, 기술적으로손쉽다는장점이있다고하였다. 17-19) 또한 T형잠금압박금속판은후방피질골분쇄를동반한불안정성골절에서도안정성을얻을수있어정확한해부학적정복및견고한고정을얻을수있다고하였다. 20) Kim 등 21) 은고령의골간단부에골결손이있는불안정한원위요골골절환자에서골결손부대체물로 calcium phosphate bone cement (CPC) 를사용하고, 수장측잠김금속판을이용하여내고정하였을때추시결과와수장측잠김금속판만을사용한후추시결과의차이가없다고보고하였다. 또한 Rhee 등 22) 은고령여성의불안정한원위요골골절에서수장측잠김금속판만을이용하여내고정하였을때, 추시상골편전위없이만족할만한치료결과를보고하였다. 한편, 여러저자들은불안정한원위요골골절에서수장측잠김금속판만을이용하여내고정하였을때, 금속판손상, 나사못빠짐현상및골편정복소실을보고하였다. 23,24) 또한다른저자들은후방분쇄골절과함께수장측피질골의분쇄및골결손이동반된경우골간단부골결손과피질골의약화로이차적인전위나관절면의붕괴가일어나기쉬울뿐더러지연유합혹은불유합이발생할수도있다고하였다. 5-8) 따라서이러한문제점들을최소화하기위해골결손부위에골이식또는대체물삽입등의부가적인시술을통한구조적인지지대가필요하다고보고하였다. 5-7,25,26) 현재임상적으로이용되는골결손부대체물로자가골이식, 동종골이식, 골시멘트, 그리고 CPC 등을삽입할수있다. Kainz 등 25) 은요골원위부의골결손을동반한분쇄골절환자에서분쇄골절부분에 CPC를사용한뒤수장측잠김금속판을이용한내고정술을시행하였을때 CPC를사용하지않은대조군과비교하여최종추시결과에서안정성을얻을수있었다고보고하였다. 또한 Büyükkurt 등 26) 은여성 37명의원위요골골절환자중골다공증이있는 20명과골다공증이없는 17명의환자에게금속판만을이용한내고정술을시행하였을때, 추시관찰시방사선학적차이는없지만골다공증환자에서관절운동제한과일상생활에제한이있음을보고하였다. 이와함께 Goto 등 27) 은고령의요골원위부의골결손을동반한분쇄골절환자에서분쇄골절부분에 hydroxyapatite 골이식을시행한뒤, 수장측잠김금속판을이용한내고정술을시행하였을때, hydroxyapatite 골이식을하지않은대 조군과비교하여최종방사선추시상만족할만한결과를보고하였다. 자가골이식은생체적합성이우수하면서적당한생역학적강도를갖고있으므로골결손이동반된불안정성골절에서골절치유를촉진한다는장점이있어전통적으로장골능에서채취한자가골이널리이용되었다. 28) 그러나자가골이식은공여부의혈종과감염, 동통, 장골능골절, 신경손상, 수술시간지연, 출혈량증가등의합병증등의보고된단점이있다. 29) 골시멘트는골실질의재형성을기대할수없고, 자가골과융합되지도않으며, 시술시의발열반응으로인해골절치유를방해할뿐아니라, 액화상태에서는세포독성이있고, 골절부외로새어나가면조직손상의위험이있다. 30) CPC는생화학적적합성과골전도능력이해면골과유사하여골대치물로많이사용되나충진된 CPC가관절밖으로흘러나와동통과관절증등합병증을유발시킬수있다는단점이있어제한적으로사용하고있다. 31) 본연구에서는고령의골다공증이있는요골원위부의심한골결손을동반한분쇄골절환자에게동종해면골이식을시행하였다. 동종해면골이식의장점으로는첫째, 이차적인전위나관절면의붕괴를막는구조적인지지대의역할을하기때문관절면에기계적안정성을부여하고정복된관절면을유지하도록하여해부학적정복을유지시키며, 둘째, 공여부의이환이없고공급의제한이없다는점, 셋째, 수술중출혈량을줄일수있고, 넷째, 이식골주위는수여자의풍부한해면골로둘러싸인부위이므로이로부터이식된동종골내부로가골이신속하게침투할수있다는점이있다. 32) 이후, 수장측잠김금속판을사용하여내고정술을시행하였고, 임상적으로만족할만한결과를보였으며, 방사선학적으로요골원위부의변형, 요골단축, 요골경사의소실, 배측경사의의미있는정복의소실이없이골유합을얻었다. 또한좀더견고한안정성을얻을수있어조기관절운동이가능하게하여일상생활로의빠른복귀가가능하였다. 수장측금속판을삽입하는경우수지굴곡건의지연성파열이발생할수있으며신경손상을유발하거나방형회내근의손상을주며전방피질골의혈액순환에피해를줄수도있으며관절면을침범한골절의경우직접관절면을볼수없다는단점이있다. 16,33) 본논문에서도정중신경압박증상이 1예에서발생하여수근관관압술을시행하였다. 또한본논문에서는관절면골절의경우먼저 C-arm fluoroscopy 를보며관절면을정복하여금속강선을이용하여고정하였으며심하게골절되어정복을잘할수없는경우에는추가적으로외고정장치를시행하거나관절경하정복술을시행하였다.

14 Hong Je Kang and Chang Hyun Shin 본연구의한계점으로는증례의수가 29 예로적고, 골이식을하지않은환자와비교연구를시행하지않았다는점이있다. 또한고령의환자를대상으로하여골결손이심한젊은환자의경우골이식시행하였을때의결과에대하여는알수없다. 이와함께외상후관절염의발생유무에대해장기추시가필요할것으로생각된다. 결 심한골결손을동반한고령의원위요골분쇄골절환자에서동종해면골이식과수장측잠김금속판을이용한치료는임상적및방사선학적으로만족할만한결과를보이는효과적인치료방법이다. 론 References 1) Edwards GS Jr: Intra-articular fractures of the distal part of the radius treated with the small AO external fixator.

VAS는평균 1.7점이었다. 최종추시시평균요골길이, 요골경사각, 수장측경사각은수술후와통계적의미있는변화는없었으며 (p>0.05), Sarmiento criteria는우수 5예, 양호 14예, 보통 7예였다. 결론 : 골결손을동반한고령의원위요골분쇄골절에서동종해면골이식과수장측잠김금속판을이용한치료는양호한결과를보이는효과적인치료방법이다. 색인단어 : 원위요골골절, 동종해면골이식, 수장측잠김금속판 접수일 2014. 6. 9 수정일 2014. 8. 18 게재확정 2014. 9. 25 교신저자강홍제익산시익산대로 460 원광대학교의과대학정형외과학교실 Tel 063-859-1360, Fax 063-852-9329, E-mail kanghongje@hanmail.net Copyright c 2015 The Korean Fracture Society.
