견봉의 형태가 회전근 개 파열에 미치는 영향

국문 초록 (Abstract)

목적: 견봉의 형태를 방사선학적으로 분석하여 회전근 개 파열에 미치는 영향에 관하여 알아보고자 한다.
대상 및 방법: 평균 나이 55.6세(범위, 27-85세)인 회전근 개 파열 91명을 환자군으로, 평균 나이 42.9세(범위, 18-72세)인 정상 견관절을 포함한 견관절 질환 환자 100명을 대조군으로 하여 MRI의 사관상 면에서 견봉의 외측 확장 정도(lateral extension)와 외측 견봉각을 측정하였고, 극상근 출구상에서 견봉의 전방 덮임 정도를 측정하였다.
결과: 회전근 개 파열 환자와 대조군에서 견봉의 외측 확장 정도는 각각 0.70±0.07, 0.64±0.10, 외측 견봉각은 72.6±6.5°, 76.4±6.5°, 견봉의 전방 덮임 정도는 0.55±013, 0.51±0.14로 측정되었으며 환자군이 대조군에 비하여 견봉의 외측 확장 정도가 더 크고 견봉각이 더 작게 측정되어 통계학적으로 유의성을 보였다(p＜0.001). 또한 환자군과 대조군에서 견봉의 외측 확장 정도와 견봉각 사이의 상관 계수는 각각 0.44, -0.46으로 통계학적으로 유의한 상관관계를 보여주었다(p＜0.001).
결론: 견봉의 외측 확장 정도와 외측 견봉각의 측정은 견봉의 형태를 결정하고 회전근 개 파열과의 상관성을 확인 할 수 있는 유용한 지표가 될 수 있을 것으로 사료된다.

Purpose: The shape of the acromion was analyzed radiologically to assess the effect on rotator cuff tears.
Materials and Methods: The rotator cuff tear group consisted of 91 patients with a mean age 55.6 years (range, 27-85 years) and the normal shoulder articular disease (control) group consisted of 100 subjects with a mean age of 42.9 years (range, 18-72 years). The lateral extension of the acromion and the lateral acromial angle were measured on an oblique coronal MRI, and the anterior covering of the acromionon was measured on a supraspinatus outlet view.
Results: The lateral extension of the acrominon of the rotator cuff tear group of patients and the control group of subjects was 0.70±0.07 and 0.64±0.10, respectively. The lateral acromial angle was 72.6±6.5° and 76.4±6.5°, respectively, and the anterior covering of the acromion was measured to be 0.55±0.13 and 0.51±0.14, respectively. In a comparison with the control group of subjects, the lateral extension of the acrominon of the rotator cuff tear group of patients was larger and the lateral acromial angle was smaller; these findings were statistically significant (p＜0.001). In addition, the correlation coefficients of the lateral extension of the acromion to the lateral acromial angle in the rotator cuff tear group of patients and in the control group of subjects was -0.44 and -0.46, respectively; a statistically significant correlation was seeen (p＜0.001).
Conclusion: The results suggest that the measurement of the lateral extension of the acromion and the lateral acromial angle determines the shape of the acromion, and thus it may represent a useful marker to confirm the interrelationship of a rotator cuff tear.
