Pendahuluan. Parameter spinopelvik merupakan parameter untuk mengukurkeseimbangan poros tulang belakang terhadap ekstrimitas bawah pada penampangsagital. Parameter ini terdiri dari sagittal vertical axis (SVA), pelvic incidence(PI), pelvic tilt (PT), pelvic incidence (PI) dan diukur melalui X-ray whole spinelateral view dalam keadaan berdiri. Pengukuran parameter ini penting sebagaidasar analisa keseimbangan sagital dalam operasi rekonstruktif tulang belakang,karena dengan tidak adanya keseimbangan pada penampang sagital ini akanberakibat timbulnya adjacent segment degeneration yang akan memengaruhiluaran klinis. Hingga saat ini belum ada studi yang mengevaluasi hubungan antaraluaran parameter spinopelvik dengan luaran klinis di indonesia.Metode Penelitian. Penelitian ini adalah penelitian analitik potong lintang dengansubyek 19 pasien dewasa pasca operasi stabilisasi dan fusi tulang belakang torakaldan lumbal di Rumah Sakit Dr. Ciptomangunkusumo (RSCM) Jakarta pada tahun2012-2014. Pasien tersebut dilakukan evaluasi X-ray parameter spinopelvik SVA,PI, PT, dan SS dilakukan penilaian skor Indeks Disabilitas Oswestry (IDO) padasaat 1 tahun pasca operasi. Lalu dilakukan analisis statistik dengan menggunakanuji hipotesis komparatif numerik dengan menggunakan pearson dimanadibandingkan luaran parameter spinopelvik SVA, PI, PT, dan SS dengan luaranfungsional skor IDO.Temuan dan Diskusi Penelitian. Didapatkan hasil korelasi antara IDO dan SVA (p<0,001) (r=0,866). Korelasi antara IDO dan PI (p=0,006) (r=0,603). Korelasiantara IDO dan PT (p=0,107) (r=0,382). Korelasi IDO dan SS (p=0,051)(r=0,454).Simpulan. Didapatkan korelasi kuat antara IDO dan SVA serta IDO dan PI.Tidak didapatkan korelasi antara IDO dan PT serta IDO dan SS. SVA dan PImerupakan parameter spinopelvik yang berpengaruh pada luaran pasca operasi fusi tulang belakang torakal dan lumbal. ABSTRACT
Introduction. Spinopelvic parameter is a parameter that used to measure thesagital balance of vertebrae in congruency with lower extrimity in sagital plane.This parametr is consist of sagittal vertical axis (SVA), pelvic incidence (PI),pelvic tilt (PT), pelvic incidence (PI) dan diukur melalui X-ray whole spine lateralview in standing position. Measurement of this parameter is important as basicanalysis for achieve sagital balance in reconstructive operation of the vertebrae,because if the sagital balance is interupted will cause the adjacent segmentdegeneration that will influence the clinical outcomes. Up until now, there is nostudy that evaluate the spinopelvic parameter with the clinical outcomes inIndonesia. Methods. This study is a cross-sectional analytic with 19 subject of adult patientthat had undergo thoracal and lumbar fusion and stabilization in Rumah Sakit Dr.Ciptomangunkusumo (RSCM) Jakarta in 2012-2014. The subject was underwentx-ray evaluation of SVA, PI, PT, and SS. The patient also underwent evaluationof Indeks Disabilitas Oswestry (IDO) score in 1 year after operation. Then thestatistical work was done with numeric comparative pearson test analysis todetermine whether there is correlation between SVA, PI, PT, and SS with IDOscore.Result and Discussion. There is strong correlation between IDO and SVA(p<0,001) (r=0,866). Strong correlation between IDO and PI (p=0,006) (r=0,603).No correlation between IDO and PT (p=0,107) (r=0,382). No correlation betweenIDO and SS (p=0,051) (r=0,454).Conclusion. Strong correlation is indicated in IDO and SVA, also in IDO and PI.There is no correlation between IDO and PT, also in IDO and SS. SVA and PI arethe important spinopelvic parameter that have influence on clinical outcome inpost thoracal and lumbar fusion and stabilization patient. ;Introduction.
