선천성 고관절 탈구 환아의 초음파 및 관절 조영술 소견 = Ultrasonography and Arthrography in Congenital Dislocation of the Hip

다국어 초록 (Multilingual Abstract)

We evaluated the use of ultrasonography and arthrography in 15 patients, 16 cases with congenital dislocation of the hip from January 1995 to December 1996. All patients in this study was managed with following management program. Ultrasound study was performed as soon as possible after admission and applied continuous skin traction in modified Bryant's method until +2 station was achieved according to Gage and Winter's traction station. When this had been accomplished, arthrogram was performed and reduction was attempted under general anesthesia. Mannual closed reduction was tried at first and if failed, open reduction was attempted. K-wire fixation or capsulorrhaphy was occasionally performed in the unstable hip after reduction was acomplished and then the hip was immobilized in a bilateral hip spica cast.
Inverted limbus was found in all cases at both ultrasonography and arthrography. Reduction was achieved by closed reduction in 6 cases, closed reduction with percutaneous K-wire fixation in 4 cases, open reduction with K-wire fixation in 2 cases and open reduction & capsulorrhaphy with K-wire fixation in 2 cases.
The effect of prereduction traction was not evaluated in our study, but ultrasound study performed as soon as possible after admission was effective method for detection of the hip abnormality & making a management plan and arthrogram performed under general anesthesia was effective method for making a reduction plan.
