Development of orthosis following EDF serial casting for infantile scoliosis

Elongation-de-rotation-flexion (EDF) casting is a popular treatment for early-onset-scoliosis (EOS). However, casting every 2 to 3 months using general anesthesia may affect cognitive function.[1,2] Aims of this study: 1) to develop a new orthosis for EOS treatment based on EDF technique (EDFO) and traction frame; 2) to evaluate emerging radiographic results from treatment. Mehta’s EDF serial casting method and AMIL traction frame were used to manually correct the spine for 3D trunk scan. Afterward, a digital spinal model was created and helped design the EDFO with CAD/CAM technology. Radiographic measurements included Cobb angle, RVAD, and thoracic height and width. Six patients (2 girls; 4 boys) diagnosed with idiopathic EOS were enrolled in the study. EDFO was applied at mean 36.5 months of age, after final EDF casting. The average major Cobb angle stabilized after treatment. Average RVAD increased. The average normalized thoracic width at last EDFO out-of-brace was less than prior to EDFO. The new asymmetric EDFO offers an alternative to serial casting and TLSO. EDFO is considered a cost-effective, safer, more breathable, removable, and less invasive modality.

Follow-up of an Elongation Bending Derotation Brace in the treatment of infantile scoliosis

Since 2013, an elongation bending derotation brace (EBDB) has been developed and applied to EOS in our institution. The goals of the study were: 1) to compare radiographic changes before the use of EBDB (Pre-B), in brace (IB), and after the use of EBDB (Post-B) in a minimal two year follow-up; 2) to determine the compliance with the EBDB. Thirteen children diagnosed with an infantile scoliosis (IS) were retrospectively recruited. Under general anesthesia in the OR, child was placed on a Spica casting table, and the spine was manipulated by stockinet straps. Then 3D child’s torso was scanned, the EBDB was designed and manufactured for exact fitting to the torso in the corrected position using CAD/CAM technology.1 Mean age at start of EBDB was 2 years and 6 months. Average follow-up was 36 months. Compliance showed a mean 19 hours per day (14 to 23 hours). Pre-treatment Cobb angle was 40°, in brace 22°, and out of brace 28° (p<0.05). Axial vertebral rotation (AVR) by Nash-Moe method improved from 30% before treatment to 21% in brace and 19% at the end of visit (p<0.05). Kyphosis was significantly increased from 16° (Pre-B) to 32° (Post-B) (P<0.05). However, there was reduction of Rib-vertebral angle difference (RVAD) from 23° (Pre-B) to 11° (Post-B) (P>0.05). A cascade of EBDB effectively corrects and stabilizes the 3D spinal deformities in infantile. Thus the EBDB is considered as a successful modality in the treatment of IS children.

Bracing for infantile scoliosis: no sedation needed

Mehta casting technique applied under anesthesia is standard treatment for infantile scoliosis (IIS). However, concern has been raised about frequent anesthesia in children less than three years. The development of a customized thoracolumbar sacral orthosis (TLSO) could avoid the risks of Mehta casting. To develop a bracing technique for IIS that achieves patient compliance and scoliosis correction. Nine patients with ISS were offered a custom TLSO as an alternative to Mehta casting. One patient declined due to an insurance issue. No anesthesia was required for measurement or fitting of the TLSO. A temperature sensitive monitor recorded wear time. Brace success was determined by radiographic correction and adherence to prescription of greater than 18 hours per day. Eight patients had brace treatment with mean(range): age 19(12–44) months, curve magnitude 34° (22–44°), rib vertebral angle of greater than 20° with follow-up 17(3–28) months. In brace correction was less than 15 degrees in 6 of 8 patients. Compliance monitor recorded wear: 4 patients ≥ 18 hours, 2 patients 16–18 hours, 1 had 14 hours, and 1 monitor malfunctioned and could not be read. Brace design evolved to maximize ipsilateral abdominal relief away from the lateral apical shift of the design. Foam lining was added to prevent skin irritation through the relief opening. Average number of braces per year =2.2. A customized TLSO can achieve in brace correction comparable to Mehta casting with acceptable compliance and without the need for general anesthesia, while allowing bathing and skin care.

Prevention of Medical Trauma in Children With Early Onset Scoliosis and the Use of Mehta Casting

Despite recent emergence of information about treatment of medical trauma in children, the literature remains sparse regarding prevention of medical trauma. Health-care professionals are in an ideal position to educate about and advocate for ways to prevent the far-reaching consequences of medical trauma, yet policies remain which at times contribute to the problem. This article presents practical approaches intended to reduce the likelihood of medical trauma in children receiving serial casting for treatment of progressive infantile scoliosis (PIS). The majority of the suggestions apply not only to children being treated for PIS, but to children receiving medical treatment for many conditions. The article also provides suggestions for parents who are enduring the stress of their child undergoing repeated surgeries and hospital stays. The authors interviewed a variety of experts in the field and draw on their own experiences as clinical social workers specializing in the treatment of post-traumatic stress disorder and developmental trauma in children.
