Some children will fall outside the expected range and yet still be fine in the end. Walking is considered to be delayed if it has not been achieved by 18 months. Delay in walking may be simply variation of normal. Other common causes include, (1) Delay in motor maturation, (2) Abnormalities in muscle tone and power, (3) Environmental factors.Aim: To determine the Odds’ ratio (OR) of the risk factors. To demonstrate differences between cases of DDH and their controls in respect to walking state. Study design: Case control study in outpatient of Al-Jumhorei teaching hospital. Consisted of 754 (377 cases of DDH, 377 controls), have been examined (295 males and 459 females), ages varies between 12 -208 months average (around 15.06 monthsStudy period: 1st Jan 2010-1st Jan 2011.Methodology: The sample of control was selected according to the method of individual matching, (MacMahon and Pugh, 1970; Gordis, 1996). For each patient with DDH one control was chosen.Results: Reveals that DDH is not a risk factor for delayed walking, moreover it has been found that it is a protective factor, Odd ratio (0.293) with highly significant association , P <0.002.Conclusion: DDH had no effect on delayed walking.Key word: Developmental hip dysplasia, Delayed walking.
