"ABSTRAK 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.

"[ABSTRAK Latar belakang. Penyuntikan berulang pada prosedur anestesia spinal berkaitan dengan tingginya angka komplikasi dan ketidaknyamanan pasien. Sistem prediksi praoperatif yang akurat terhadap kemungkinan kesulitan penempatan jarum spinal dapat membantu mengurangi insiden penyuntikan berulang sehingga mengurangi risiko komplikasi terhadap pasien. Penelitian ini bertujuan untuk mengetahui ketepatan prediksi kesulitan penempatan jarum spinal berdasarkan gambaran radiologis dan penanda anatomis pada pasien bedah urologi. Metode. Penelitian ini bersifat observasional analitik terhadap pasien bedah urologi yang menjalani anestesia spinal di Rumah Sakit Cipto Mangunkusumo pada bulan April sampai Mei 2015. Sebanyak 109 subyek diambil dengan metode consecutive sampling. Data pasien (usia, jenis kelamin, indeks massa tubuh, status fisik, gambaran radiologis vertebrae lumbal, dan kualitas penanda anatomis tulang belakang), jumlah penusukan kulit dan redireksi jarum spinal, serta angka kesulitan penempatan jarum spinal dicatat. Kesulitan penempatan jarum spinal ditentukan berdasarkan jumlah penusukan kulit dan redireksi jarum spinal. Variabel yang signifikan ditentukan melalui uji Pearson?s Chi-square dan uji Fisher, kemudian analisis multivariat dengan metode regresi logistik digunakan untuk melihat hubungan antara kesulitan penempatan jarum spinal dengan variabel-variabel yang signifikan. Hasil. Faktor usia memiliki hubungan yang bermakna hanya pada analisis bivariat (p=0,028). Kualitas penanda anatomis dan gambaran radiologis vertebrae lumbal memiliki nilai prediksi terhadap kesulitan penempatan jarum spinal (p=0,000 dan p=0,006). Hasil uji kalibrasi menunjukkan kualitas prediksi yang baik. Dari uji diskriminasi didapatkan AUC sebesar 0,84 (IK 95% 0,751-0,929). Simpulan. Kualitas penanda anatomis dan gambaran radiologis vertebrae lumbal mampu memprediksi kesulitan penempatan jarum spinal dengan tepat pada pasien bedah urologi. ABSTRACT Background. Multiple attempts at spinal puncture have been related to many complications and patient discomfort. Accurate preoperative prediction of spinal needle insertion difficulty would reduce the incidence of multiple puncture and minimize the complications consequently. This study was designed to determine the accuracy of lumbar vertebrae radiological characteristics and spinal bony landmark quality in predicting the difficulty of spinal needle insertion in patients undergoing urologic procedure.

Methods. This was an analytic observational study in urologic patients scheduled for spinal anesthesia at Cipto Mangunkusumo hospital between April and May 2015. A total of 109 subjects were included in the study by consecutive sampling. Patient data (age, sex, body mass index, physical status, radiological characteristics of the lumbar vertebrae, and quality of spinal bony landmark), number of skin puncture and needle redirection, and the prevalence of spinal needle insertion difficulty were recorded. The first skin puncture success and number of needle redirection were used to assess the difficulty. Significant variables were first determined by Pearson?s Chi-square and Fisher test, and then multivariate analysis using logistic regression method tested the association of the skin puncture success and number of needle redirection with the significant variables.

Results. Age was significant only in bivariate analysis (p=0,028). The quality of spinal bony landmark and the radiological characteristics of the lumbar vertebrae had predictive value on spinal needle insertion difficulty (p=0,000 and p=0,006 respectively). Calibration test showed that the prediction quality was good. The discrimination test resluted in AUC of 0,84 (CI 95% 0,751 to 0,929).
