Problems solved by technology

[0013] While a number of restraints and devices are known for holding an infant in a proper position for hip development, there is no known device for positioning the infant's hips in a slightly flexed and abducted physiologic position and keep the infant in the supine position, which is the recommended position for reducing the incidence of SIDS

Embodiment Construction

[0035] Figure 4-5B An embodiment of a device 10 for positioning the hip of a baby and for maintaining the hip joint in a physiological neonatal position is described. The hip positioning device 10 includes a flexible base 11. In this embodiment, the base 11 includes an integral element having a soft filler 12 therein.

[0036] The base 11 has a pair of opposite side portions 13 extending outward.

[0037] Here, the side portion 13 shown is substantially rectangular, but this is not considered as a limitation. The size of the side portion 13 is designed to support the thigh 14 of the infant 15 (described as a toy here) at an acute angle greater than zero relative to the plane of the back of the infant 15, and the knee 16 of the infant 15 is in a bent position. In this embodiment, the padding 12 in the base 11 is tailored to achieve the optimum amount of lift and bend to position the baby's hip 17 in the desired orientation. In one embodiment, the height 18 of the side portion 13...

Abstract

A device and method are provided for positioning an infant's hips, and for maintaining the hip joint in a physiological position, during early months of life. The hip-positioning device includes a flexible base having a pair of opposed, outwardly extending side portions. The side portions are dimensioned for supporting thighs of an infant at an acute angle greater than zero relative to a dorsal plane of the infant, with knees of the infant in a flexed position. The base further has a downwardly extending, generally central portion that is adapted for positioning between the infant thighs and dimensioned for retaining the infant thighs in an abducted position. The device additionally includes an element for retaining the base on the infant.

Description

Technical field [0001] The present invention relates to orthopedic devices, and more specifically, to orthopedic devices for fixing the hip joints of infants. Background technique [0002] Hip dysplasia is a medical term for instability or looseness of the hip joint, which affects thousands of children every year. Hip dysplasia occurs when the ball of the hip (called the femoral head) is not properly positioned in the acetabulum (see Figures 2A-2D, which are used to describe normal and partially dislocated and dislocated hip joints). This condition is usually diagnosed in infants and ranges from mildly unstable to complete dislocation. Approximately one in every twenty full-term babies has some hip instability, and of these, 2-3 out of every 1,000 will require treatment. See Figure 1, which is used to describe the anatomy of the hip. [0003] This frequency varies with gender, race, and other factors, including the position of childbirth. Statistically, girls have a higher inci...
