Resumen
Sacroiliac joint dysfunction (SIJD) and leg length discrepancies are commonly associated with each other and the two entities are often implicated as possible precursors of a number of musculoskeletal disorders in the general population. This study investigated the prevalence of asymptomatic sacroiliac joint dysfunction (ASIJD), leg length discrepancy (LLD) and the association between the two entities in male students in selected junior secondary schools in Ibadan. Two hundred and three male junior secondary school students aged 10- 15 years participated in this study. Participants were screened for SIJD using four standardized palpatory tests and for real and apparent leg length discrepancies using standardized tape measure techniques. Chi-square test was used to investigate the association between ASIJD and prevalence of LLD at alpha level of 0.05.The prevalence of ASIJD among participants in this study was 21.7%. Sixty five percent and 52.0% of the participants had real and apparent LLD >0.5cm respectively. The 26.0% prevalence of ASIJD among participants with real LLD > 0.5cm was significantly higher than prevalence in those with apparent LLD. We concluded that one out of every five male students in the study population had ASIJD and this was significantly associated with RLLD.

Résumé
Les disfonctionnements des articulations sacro-iliaques asymptomatiques (ASIJD), la disparité de la longueur des jambes (LLD) sont communément associés l’un l’ autre et sont souvent impliqués
comme précurseurs des nombreux désordres musculo-skeletal chez la population. Cette étude investiguait la prévalence des disfonctionnement des articulations sacro-iliaques asymptomatiques
(ASIJD), la disparité de la longueur des jambes (LLD) et l’association entre les 2 chez les collégiens dans des collèges sélectionnés à Ibadan. Deux cent trois males, collégiens entre 10-15 ans participaient à cette étude. Les participants faisaient un dépistage pour le SIJD utilisant quatre tests standard de palpation et la disparité des jambes les techniques standard de mesure. Le test de Chi square était utilisé pour investiguer l’association entre ASIJD et le taux du LLD avec le niveau d’alpha de 0.05. Le taux d’ASIJD parmi les participants dans cette étude était de 21.7%. Soixante cinq pour cent et 52.0% des participants avaient un réel et apparent LLD > 0.5cm respectivement. Le taux de 26.0% d’ ASIJD parmi les participants ayant le réel LLD > 0.5cm était significativement plus élevé que le taux chez ceux ayant LLD apparent. Nous concluons que un de chaque cinq étudiant male dans la population étudié avait l’ASIJD et ceci était significativement associé avec le RLLD.
