초음파를 이용한 한국인 정상고관절의 계측에 관한 연구 = An Ultrasonographic Study on Measurement of Normal Hip Joint in Korean

다국어 초록 (Multilingual Abstract)

The ultrasonography is very useful in evaluation of small amount of effusion in hip joint and has several advantages such as noninvasiveness easiness accuracy and no radiation hazard. The data of normal hip joint space and capsule is very important in ultrasonographic evaluation of inflammatory hip joint disease. However normal ultrasonographic data of hip joint has not been reported except in pediatric age. The purpose of this study was to evaluate and measure normal hip joint space and capsule and to provide the basic data for the clinical application, Healthy 70 males and 70 females who have had no past history and present clinical symptom of hip joint were examined with real time sector scanner (5MHz transducer) Width of hip joint spaces and thickness of joint capsule were obtained and analysed by statistical analysis. The results were as follows; 1. The average width of the hip joint space were 2.6$\pm$ 0.6mm(left) in females. There was no significant difference by sex. 2. The widths of the hip joint space were increased with aging and decreased after 6th decade(male) and 5 th decade(female). 3. The maximal difference of both hip joint spaces was 1.2mm and there was no significant difference in both side by sex and age. 4. The average thicknesses of hip joint capsule were 1.9$\pm$0,3mm(right) 1.7$\pm$0,2mm(left) in females. There wan no significant difference by sex. 5. The thicknesses of the hip joint capsule were increased with aging and were in plateau after 5th decade(male and female). 6. The maximal difference of both hip joint capsules was 0.9mm and there was no significant difference in both sides by sex and age. It is therefore considered that ultrasonography could be a very useful modality in diagnosis of hip joint disease in which the hip space and the hip joint capsule are changed by various etilolgies.
