Abstract:
Objective To investigate the prevalence of gluteal muscle contracture (GMC) in teenagers,and the influences of the mild and moderate GMC to hip bone development,and to propose the epidemiological reference to the physical examination for navy pilot recruitment.Methods From 1999 to 2011,50 960 graduated male high school students were examined for pilot recruitment.The yearly detection rates of gluteal muscle contracture were calculated and compared each other.Then the students,who were diagnosed as type A and B GMC were examined by X-ray photographs of their hips for assessment.The results were compared with the control group,that was the healthy students come from same area with 1 ∶ 1 number ratio to the A and B GMC's,to determine the influence of mild and moderate GMC on the development of hip joint.Results In 13 years,1 301 (2.55%) students were diagnosed as GMC.The detection rate of the disease were in the downward trend (x2 =55.791,P<0.01).The GMC detection rate was respectively 2.46% and 2.67% in urban and rural students and showed insignificant difference.According to the examination of X-ray photographs,there were no significant differences between type A and type B GMC students and the control groups.Conclusions The GMC prevalence is decreasing year by year.But the propaganda and education work are still need to be strengthened in order to have more patients treated timely.The X-ray assessment results indicate that the mild or moderate GMC would not influence the skeletal development of hip joint.If there were enough biomechanics and kinematics studies supported the mild or moderate GMC students would be assessed as pass in surgical examination.
