Abstract

If a patient wearing arm sliding due to shoulder dislocation or fracture is impossible with abduction, the velpeau view is performed instead of superior-inferior axial projection view. However, it aggravates the patient's pain because it is difficult for the patient with dislocation or fracture to pull back the shoulders. Therefore, I suggest a new method of the 'modified velpeau view' that allows patients to lower their heads at examination. In order to investigate the easiness of fixing posture at examination and clinical utility, I conducted a study comparing the bone structures at the velpeau view and those at the modified velpeau view depending on wall-bucky and the patients' leaning forward angle ($30^{\circ},\;45^{\circ},\;60^{\circ}\;and\;75^{\circ}$), with the subjects of 20 velpeau view-prescribed patients amongst who had come to my hospital suspected of dislocation of shoulder or fracture and 30 healthy people from October of 2009 to January of 2010. Department of radiologists and orthopedics specialists evaluated the pictures for scales 0 to 5(best grade) under the given criteria. As a result of comparison in bone structures depending on wall-bucky and the leaning-forward angle in the group of healthy people, the velpeau view and the modified velpeau showed a similar diagnostic utility at $45^{\circ}$ and $60^{\circ}$. The picture evaluation result for proving diagnostic value showed that the anterior and posterior of shoulder heads and the anterior and posterior of glenoid fossa could be observed in the velpeau view; on the other hand, besides these areas acromioclavicular joint and coracoid process could be viewed in the modified velpeau view. This result verified that the modified velpeau view could replace the velpeau view for its diagnostic value as an examination method. This result, moreover, suggests that the modified velpeau view needs to be studied and improved from a variety of perspectives not only for an alternative for patients having troubles with the velpeau view position but also for clinical application of new test method for diagnosis of shoulder disorders other than dislocation of shoulder or fracture.

견관절 탈구나 골절로 인해 arm sliding를 착용한 환자에서 외전(abduction)이 불가능한 경우 superior-inferior axial projection view를 대신하여 시행하는 velpeau view는 탈구나 골절 환자가 상체를 뒤로 젖히는 자세를 취하기가 어려워 고통이 가중되었다. 하지만 환자의 상체를 숙여 검사하는 새로운 검사법인 'modified velpeau view'를 제안하며 검사 시 자세고정의 용이함과 임상적 유용성에 대해 알아 보고자 2009년 10월부터 2010년 1월까지 견관절 탈구나 골절로 의심되어 본원에 내원한 환자들 중 velpeau view 처방을 받은 환자 20명과 정상인 30명을 대상으로 velpeau view와 modified velpeau view에서 wall-bucky와 환자의 상체 숙임각(30도, 45도, 60도, 75도)의 변화에 따른 골 구조의 차이를 비교하였다. 영상의학과 전문의와 정형외과 전문의에게 영상평가 기준을 제시하고 0점부터 5점을 만점으로 영상이 평가되었다. 정상인군에서 wall-bucky와 상체의 숙임각 변화에 따른 골구조의 비교결과 45도와 60도가 velpeau view 와 비슷한 진단수준을 보였으며, 진단 가치를 증명하기 위한 영상평가 결과 velpeau view에서는 shoulder head의 anterior와 posterior, glenoid fossa의 anterior와 posterior를 관찰할 수 있었지만, modified velpeau view에서는 velpeau view에서 관찰되는 부위 뿐만 아니라 acromioclavicular joint와 coracoid process도 관찰할 수 있었다. modified velpeau view가 velpeau view와 비교시 velpeau view를 대체할 만한 수준의 진단적 가치를 지닌 유용한 검사임이 확인 되었다. 또한 modified velpeau view는 velpeau view position이 어려운 환자를 대상으로 적용 가능한 대체법으로서 뿐만 아니라 어깨 골절과 탈구 이외의 어깨 질환의 진단을 위한 새로운 검사로서의 임상적 적용을 위해 다양한 시각에서의 연구와 개선의 노력이 필요함을 시사한다.
