However, to the author s knowledge, there is no report on the follow-up outcomes focused on remnant cysts. Materials and Methods: Six (n=6) patients with spinoglenoid ganglion cyst accompanied by suprascapular nerve palsy, with a mean follow-up of 15 months (12-23months) following arthroscopic cyst decompression and superior labral repair, were enrolled. Residual cyst was investigated by ultrasonography and MRI. Results: Immediate postoperative ultrasonography revealed complete remission of ganglion cyst in one patient and reduced ganglion cyst size in five patients. Three-month follow-up ultrasonography showed spontaneous complete remission of the residual cysts in all patients. No recurrence on MRI was seen at one-year follow-up. Conclusion: Residual spinoglenoid ganglion cyst remaining after arthroscopic decompression and superior labral repair tends to resolve spontaneously within 3 months of surgery. Key Words: Spinoglenoid ganglion cyst, Superior labral lesion, One-way check valve, Arthroscopic decompression 통신저자 : 박형빈경상남도진주시칠암동 90 번지경상대학교의학전문대학원정형외과학교실 Tel: 055) , Fax: 055) , hbinpark@gnu.ac.kr 접수일 : 2010 년 3 월 23 일, 1 차심사완료일 : 2010 년 4 월 1 일, 2 차심사완료일 : 2010 년 4 월 26 일, 게재확정일 : 2010 년 5 월 7 일 111

대한견 주관절학회지제 13 권제 1 호 진단적관절경상전례에서상부관절와순전후방병변과낭포와관절사이에비정상적인연결을확인할수있었다 (Fig. 3A). 결정성낭포의감압술은탐촉자를이용하여관절과낭포의연결부를확장후낭포를압박하여시행하였으며, 이후상부관절와순봉합술을시행하였다 (Fig. 3B, 3C).

2 cm (1.2-3.3/2-3.7/0.7-1.7) 크기의낭포가잔존하였다 (Fig. 4A). 술후 3개월에시행한초음파상전례에서낭포가완전소실되었으며 (Fig. 4B), 술후 1년에시행한자기공명영상에서재발은없었다 (Fig. 5), (Table 1). 5예에서술후평균 11 개월 (9~13) 에극 하근의근력및근위축이건측과비교하여완전히회복되었다 (Fig. 6).

고찰극관절와결절성낭포는흔히관절와순병변과동반되며, 영상의학적으로관절와순의병변이발견되지않는경우라도진단적관절경에서상부관절와순의병변과동반된경우가흔해몇몇저자들에의해두병변의관련성이보고된바있다 9,10).

5 성창민 : 극관절와결절성낭포의관절경적감압술및상부관절와순봉합술후잔존낭포의경과 - 증례보고 - 견갑상신경은경추 5번과 6번신경으로부터기시하여횡견갑인대밑으로견갑상절흔을통과한후극상근에지배분지를제공하고, 극와절흔을지나극하근을지배하는감각운동신경으로견갑상절흔과극와절흔부위에서흔히압박된다 8). 견갑상절흔에서압박된경우견관절통증, 극상근과극하근의근력약화및위축이나타나는반면, 극와절흔에서압박된경우는주로극하근에한정된증상만나타난다 4,8). 특징적인신체검사소견은견갑상신경압박에따른극하근의근력약화및위축이관찰되고, 극와절흔부압박시통증이유발되는경우이다. 확진은초음파, 자기공명영상, 진단적관절경으로가능하다 6). 비수술적치료방법으로흡인술이있으며, 수술적방법으로는개방적제거술, 관절경하낭포의감압술및상부관절와순봉합술, 상부관절와순단독봉합술등이있다 3,6,9,10). Piatt 등 6) 과 Antoniou 등 1) 은극관절와결절성낭포로유발된견갑상신경증에대한치료방법들의비교연구에서환자의만족도는수술적치료군이비수술적치료군보다높은만족도를보였다고하였고, 관절경을이용한감압술이개방적절제술과비교하여임상결과가비슷할뿐아니라, 관절내치료시동반병변의관찰이가능하고술후이환율이낮아관절경적수술을추천하였다. 많은후속연구들에서도관절경적감압술및관절와순봉합술이극관절와결정성낭포의치료법으로우수한결과를나타낸다고하여최근치료의대세를이루고있다 1,3,5,6,9). Schroder 등 9) 은낭포의감압없이관절와순병변의단독봉합만으로도추시결과낭포가소실되었다는보고를통해극관절와결절성낭포의발병원인으로한방향역행방지밸브효과가그기전이라는이론을지지하는근거를제시하였다. 본증례들에서도 6예중 5예에서수술직후시행한초음파에서는낭포가남아있었으나, 술후 3개월추시에서전례에서낭포가소실되었고, 술후 1년째재발이없었던것에근거하여잔존하는낭포는관절와순병변의봉합으로한방향역행방지밸브효과가제거됨으로써자연소실되었다고생각된다. 결론극관절와결절성낭포에대하여관절경적감압술및 상부관절와순봉합술로치료시, 낭포의완전한감압을시행하지않더라도잔존낭포는 3개월이내에자연소실되는경향이있었다. 하지만저자들의증례가적어명확한결론을위하여는보다많은증례연구가필요하다고생각한다.
