Derotational casting for progressive infantile scoliosis

Area of Science:

• Orthopedics
• Pediatric Spine Surgery
• Scoliosis Treatment

Background:

• Progressive infantile scoliosis requires effective treatment options.
• Serial cast correction using the Cotrel derotation technique is a potential therapeutic approach.

Purpose of the Study:

• To review early experiences with serial cast correction for progressive infantile scoliosis.
• To identify patient subgroups that benefit from or fail this treatment.

Main Methods:

• Prospective and retrospective follow-up of 55 patients with progressive infantile scoliosis treated since 2003.
• Data collected included etiology, Cobb angles, rib vertebral angle difference, rotation, and lung space.

Main Results:

• 55 patients with progressive infantile scoliosis showed improvement with serial cast correction.
• Younger age at initiation, moderate curve size (<60 degrees), and idiopathic diagnosis correlated with better outcomes.
• Space available for the lung improved from 0.89 to 0.93; no worsening of rib deformities occurred.

Conclusions:

• Serial cast correction is highly effective for infantile scoliosis, especially in young idiopathic cases (<60 degrees) initiated before 20 months.
• This technique offers curve improvement and delays surgery in older or syndromic patients, also enhancing chest and body shape.
