PERINATAL FACTORS AND DEVELOPMENTAL DISPLACEMENT OF THE HIP

Abstract

Cilj rada. Procijeniti povezanost perinatalnih čimbenika i razvojnog poremećaja kuka u novorođenčadi i dojenčadi u našoj sredini. Metode. Istraživanje je provedeno na skupini od 140 rodilja i djece s ultrazvučno dijagnosticiranim razvojnim poremećajem kuka te 420 rodilja i djece u koje je isključen poremećaj, kao kontrolne skupine. Ultrazvučni pregledi vršeni su linearnom sondom od 6,2 MHz, a rezultati prikazani ultrazvučnom klasifikacijom kuka i opisom nalaza po Grafu. Analizirani su: životna dob i paritet rodilja, komplikacije u trudnoći, za vrijeme i nakon poroda, način poroda, gestacijska dob, spol novorođenčeta, porodna težina, porodna duljina, ponderalni indeks, Apgar indeks i neonatalne komplikacije. U statističkoj analizi korišteni su ANOVA, 2 test i Studentov t-test. Rezultati. Od ukupno 2511 novorođenčadi u 140 (6,9%) dijagnosticiran je razvojni poremećaj kuka, značajno veće učestalosti u ženskoga spola (72,9%), stava zatkom (10,7%), carskog reza (25,7%), starije životne dobi i višeg pariteta rodilja, novorođenčadi porodne težine >4000 g i ponderalnog indeksa >2,85 te na oba kuka (49,3%). Zaključak. Istraživanje je ukazalo na veću učestalost ove deformacije u ženskog spola, stava zatkom, velike porodne težine i ponderalnog indeksa novorođenčadi, što povezujemo s mehaničkim i hormonalnim čimbenicima rizika.Objective. The aim of this study was to evaluate the relationship of perinatal factors and developmental displacement of the hip in our setting. Methods. The study inculuded 140 mothers and children with developmental displacement of the hip and 420 mothers and healthy children, as a control group. Ultrasound was applied with a 6.2 MHz linear scanner and results were classified according to Graf. The following factors were analyzed: age and maternal parity, complications in pregnancy, during and after delivery, fetal posture, type of delivery, gestational age, newborn sex, birth weight, birth length, ponderal index, Apgar score and neonatal complications. ANOVA, Chi-square and Student t-test were used for statistical analysis. Results. From a total 2511 newborns, 140 (6.9%) children were diagnosed with developmental displacement of the hip, which incidence where significantly higher in females (72.9%), in breech presentation (10.7%), cesarean section (25.7 %), higher maternal age and parity, birth weight >4000 g, ponderal index >2.85 and bilateral (49.3%) cases. Conclusion. Female sex, breech presentation, high birthweight and ponderal index were confirmed as risk factors for developmental displacement of the hip, which connects to intrauterine mechanical and hormonal risk factors
