Hip dislocation in children can occur congenitally in isolation or in conjunction with other congenital abnormalities. Traumatic hip dislocations in children are relatively uncommon and anterior dislocation of hip joint is even rarer. We report such a case following unusual mode of injury in a 12-year-old child. The patient underwent successful emergent closed reduction of left hip. The clinical course and follow-up assessment of the patient was otherwise uneventful. At 2 years' follow-up there was no evidence of osteoarthritis, coxa magna, heterotrophic calcification, in congruency of the joints or avascular necrosis of the head of femur.

OBJECTIVETo develop an intelligent adjustable leg raising system which could realize the quantification and visualization of lower limbs' elevation angle and frequency.

METHODSWe determined the pole adjustable length of thighs and cruses and the flexion angle range of hips and knees according to the requirements of clinical lower limb function rehabilitation, and made force analysis of hip's and knee's flexion motivation mechanism and clinical observation on its security and effectiveness.

RESULTSThis device was small and compact in overall appearance, which could adjust the angle of the hips and knees bending and ankles turning alone. The force analysis of the hips and knees flexion power element was consistent with the design requirements. The preliminary studies showed the device could relieve pain, improve the range of motion and promote the rehabilitation, which was superior to that of the Brown Ska (P < 0.05).

CONCLUSIONThe intelligent adjustable leg raising system meets the requirements of clinical usage, which is suitable for different heights, and the flexion angle ranges of hips and knees are wide and in high accuracy, which is worth of being improved and generalized.
