Purpose: The purpose of this study is to evaluate efficacy of percutaneous pinning of distal radioulnar joint in patient with distal radius fracture. Methods: Thirty-eight patients who underwent percutaneous pinning and external fixation for distal radius fracture were included in this study. Radiologic and clinical outcomes were compared between the patients who underwent percutaneous pinning on the radius only (PD group) and the patients with supplementary pinning on distal radioulnar joint (DRU group) after percutaneous pinning on the radius. External fixation was performed in all patients. Results: Twenty-three patients were PD group and fifteen patients were DRU group. Radial height and radial inclination was significantly higher in DRU group. There was no significant difference in ulnar variance, volar tilt and articular step off between two groups. Among the clinical outcome, there was no significant difference in range of motion between two groups but grip strength was significantly larger in DRU group. Conclusion: Percutaneous pinning with K-wires on distal radioulnar joint in distal radius fracture can be a useful procedure for prevention of radial shortening without loss of range of motion of the wrist.

PD 그룹에서는 23명의환자중 4예에서 1개의 K-강선을사용하였고, DRU 그룹에서는 15명의환자중 3예에서 1개의 K- 강선을사용하였다. 나머지환자에서는모두 2개의 K-강선을사용하였다. 원위요척관절핀고정술의경우척골의경상돌기하단에서시작하여원위요척관절을통과하여요골의연골하골을지지하며삽입하였다. 수술후 4주후외래에서 K-강선을제거하고, 6주째외고정기를제거한후물리치료와재활치료를시행하였다. 추시는수술후 2주, 4주, 6주, 3개월에추시하였다. 3. 통계학적방법통계는 PD 그룹과 DRU 그룹간의방사선학적및임상적결과를 paired t-test를이용하여비교분석하였다. 통계프로그램은 PASW ver (SPSS Inc., Chicago, IL, USA) 을사용하였다. 결과 PD 그룹의평균연령은 63.1 (±8.6) 세였고, DRU 그룹의평균연령은 64.5 (±8.7) 세로두군간에통계학적인차이는없었다. 요추부골밀도는 PD 그룹에서 T점수가 (± 0.91) 이었으며, DRU 그룹에서 (±0.58) 로두군간에유의한차이를보이지않았다 (Table 1). 수술전방사선학적결과는비관혈적정복술후에석고부목을유지한상태에서시행한방사선사진에서측정하였다. PD 그룹에서는요골높이가 7.23 (±1.92) mm, DRU 그룹에서 7.43 (±2.03) mm로나타났다. 요골경사각 (radial inclination) 의경우 PD 그룹에서 (±3.23 ), DRU 그룹에서 (±2.72 ) 로나타났다. 척골변위 (ulnar variance) 는 PD 그룹에서 0.34 (±0.23) mm, DRU 그룹에서 0.29 (± 0.12 )mm로나타났다. 수장측경사의경우 PD 그룹에서 (±4.78 ), DRU 그룹에서 (±3.78 ) 로나타났다. 관절면부조화 (articular step off) 에서는 PD 그룹에서 1.34 (±0.45 )mm, DRU 그룹에서 1.41 (±0.37) mm로나타났다 (Table 1). 수술후방사선학적결과에서는요골높이 (radial height) 가 PD 그룹에서 (±1.81) mm, DRU 그룹에서 (± 2.15) mm로 DRU 그룹에서유의하게큰것으로나타났다 (p=0.013). 요골경사각 (radial inclination) 의경우 PD 그룹에서 (±4.98 ), DRU 그룹에서 (±2.62 ) 로역시 DRU 그룹에서유의하게높은것으로나타났다 (p=0.026). 수술후척골변위 (ulnar variance) 는 PD 그룹에서 0.13 (±1.10) mm, DRU 그룹에서 0.20 (±1.27) mm로두군간에통계학적인차이는없었다. 수술후수장측경사는 PD 그룹에서 9.00 (±4.52 ), DRU 그룹에서 9.67 (±3.42 ) 로두군간에통계학적인차이는없었다. 관절면부조화 (articular step off) 에서는 PD 그룹에서 0.04 (±0.21) mm, DRU 그룹 Table 1.

6 J Korean Soc Surg Hand Vol. 20, No. 1, March 2015 가필요한환자에서관혈적방법을추천하였다. Kreder 등 9 은 179명의관절을침범한전위된원위요골골절환자를대상으로금속판내고정술과도수정복후금속강선및외고정기고정술을비교한무작위연구에서수술후첫 2년동안은비관혈적인치료를받은환자에서관혈적치료를받은경우보다일상생활로의복귀나기능적측면에서더우수한결과를보였고수술후 1년이후에는기능적결과의변화가없으므로 1년이상의추시는필요없다고하였다. 본연구에서는이와같이비관혈적인치료인도수정복후핀고정술및외고정기고정술의장점을극대화시키고자보조적인경피적원위요척관절핀고정술을추가로시행하였고그결과기존의금속강선및외고정기고정술의방법보다임상적으로는수부의파악력의세기가우수하였고, 방사선적으로는요골높이와요골경사각의회복이우월하였다. 본연구의한계는추시기간이 3개월로짧았기때문에장기적으로외상후관절염등에대한연구가필요할것이다. 결론 원위요골골절의외고정과경피적핀고정술을시행한결과비교에서방사선학적으로요골에만핀고정을시행한환자에비해요골과원위요척관절에핀고정을시행한환자군에서요골높이 (radial height) 와요골경사 (radial inclination) 가유의하게큰것으로나타났다. 임상적으로는수부파악력이요골과원위요척관절에핀고정을시행한환자군에서유의하게큰것으로나타났다. 불안정원위요골골절의수술적치료에서경피적원위요척관절핀고정술은수근관절의움직임제한없이요골단축을방지할수유용한술식이될수있을것으로생각된다.
