Pediatric Hip Abduction Orthosis  

What it does:  The Pediatric Hip Abduction Orthosis is primarily used for managing the range of motion of the hip and is more comfortable for the patient; is also used for post-op hip surgeries. This abduction orthotic is preset to a certain hip abduction angle in order to help reach maximum control during walking. The range of hip flexion and extension is controlled to 20-degree increments throughout the gait cycle.

Indicated For:  Leg Calve Perthes Disease


Illfeld pediatric hip abduction splint 

What it does:  The Illfeld pediatric hip abduction splint is used to control abductor spasms in the hip.

Materials Used:  “The Ilfeld Splint consists of two aluminum thigh bands fastened to a stainless steel cross bar with swivel joints. The metal thigh bands are covered with fabric or dipped in plastisol. The thigh bands are adjustable and are locked in place with a 3/16″ hexagon wrench.”

Indicated For:

  • Congenital dislocation of the hip
  • Congenital dysplasia of the hip
  • Hip dysplasia
  • Dislocation due to cerebral palsy and other neuro-muscular conditions

A Frame orthoses 

What it does:  The A frame orthoses correct the problems associated with rotational and angular malformations.  This type of orthotic is used to apply corrective forces for more proximal malformations.

Materials Used:  “Calf and thigh bands and pressure pads are attached to an “A”-shaped metal frame. All components are either adjustable or available in several sizes, so that children of varying heights and girths can be accommodated.” (ACPOC)

Indicated For:

  • Femoral torsion
  • Angular deformities
  • Rotational deformities

HKAFO (Hip Knee Ankle Foot Orthosis)

What it does:  The HKAFO is a KAFO (knee-ankle-foot-orthosis) with an extension of hip joint and pelvic devices.  This orthotic is used for patients/clients requiring extra stability of the hip due to paralysis and weakness that also accompany lower extremity involvement.  The HKFO brace will provide pelvic stability in all planes of movement.  The hip joint of the brace stabilizes and aligns the lower leg, which reduces undesired motion and increases steps per minute and reduces energy expenditure. (Brownfield’s)

Materials Used:  Hip joint and pelvic bands

Indicated For:

  • Hip instability
  • Hip weakness
  • Patients with paraplegia
  • Spina bifida
  • Recurrent hip dislocation
  • High neurological impairment

The Newport Jr Hip System with the new PJ Virtual Pediatric Joint

What it does:  The Newport Jr Hip System is mainly for stability and control with the range of motion. Can be used after surgery to increase function. The Newport improves alignment of the hip by forcing appropriate acetabular and femoral molding. This decreases the possibility of future subluxations and dislocations.

Materials Used:  Replacement liner for the entire orthosis and replacement liners for individual components

Indicated for:

  • Hip joint malalignment
  • Postoperative stabilization
  • Subluxed hips requiring better alignment to relieve pain
  • Tight hip adductor, abductor, flexor, and/or extensor muscle groups
  • Patients with impaired sitting and standing balance

Anti-adduction hip arthosis

What it does:  The anti-adduction hip arthosis prevents leg scissoring.

Materials Used:  Co-polymer cuffs and condylar wedges with Velcro

Indicated For:

  • Low grade cerebral palsy
  • Over active hip adductors
  • Muscle imbalances caused by upper motor neuron lesion

Pavlik Harness

What it does:  The Pavlik Harness is used for children that have not yet reached walking age.  The harness consists of straps across the shoulders and chest and also includes stirrups for the feet.  Hips are kept within flexion and abduction limitations, but the child is still allowed to move within acceptable ranges.  The Pavlik harness provides an alternative to hip casting, which can lead to possible skin integrity issues.

Indicated for:

  • Congenital hip dislocation

Sure Step De-Rotation

What it does:  The Sure Step De-Rotation orthotic provides dynamic stability for mild cases of femoral and tibial torsion.  The orthotic is useful with patients that have both unilateral or bilateral leg involvement.  It can be attached to existing footwear of the child and can be hid under the child’s clothes. The Sure Step De-Rotation orthotic is not indicated in children that have fixed rotational deformities.

Indicated for:

  • Internal or external femoral or tibial rotation that is not fixed

Abduction Bars

What it does:  Abduction bars are used post-surgically to keep hips at an optimal abducted/adducted position during restricted ambulation.  Some abduction bar orthotics are made with neoprene, which is a light and breathable material.

Indicated for:

  • Legg Calve Perthes
  • Post-surgical hip conditions


What it does:  SWASH is an acronym for “Standing Walking And Sitting Hip” orthotic.  It provides control of hip abduction throughout the range of dynamic sitting and standing.  The orthotic has a padded strap that is positioned around the waist and plastic thigh bands.  The waist and thigh bands are connected by two joints and leg bars.  The orthotic reduces scissor gait and reduces adduction and internal rotation.

Indicated for:

  • Cerebral Palsy
  • Child who is adducted and internally rotated
  • Lateral migration of the femoral head


What it does:  The RGO stands for Reciprocating Gait Orthotic and is useful for a child that has a neurologic impairment of the lower extremity.  The child must have retained hip flexion and hip adduction.  The RGO “mechanically translates hip extension on one side into hip flexion on the contralateral side.”  The device can be used for stability during walking and as a stander to allow arm movements for functional activities.

Indicated for:

  • Children with L1-L3 lesion with preserved iliopsoas and hip adduction

Frejka Splint

What it does:  The Frejka pillow splint keeps the legs in an outwardly rotated position to ensure that the head of the femur locates with the acetabuli. If the hip is displaced at birth, the Frejka splint will be issued to the infant and worn for 1-2 months.

Indicated for

  • Legg Calve Perthes
  • Congenital dislocation of the hip
