Purpose: To describe the role of osteotomies in rigid spinal deformities

Patients and Methods: One hundred fifty six patients with spinal deformities undergoing surgery between March 1998 and August 2005 were identified from our spine registry. Our study cohort included 23 cases where osteotomies were performed for correction.

Corrective osteotomies were one of: 1) wedge osteotomy convex based; 2) wedge osteotomy dorsally based; 3) complex wedge or eggshell osteotomy for combined frontal and sagittal plane deformity. Patient’s demographics, type of deformity, underlying conditions, operative results, complications, and need for secondary procedures were documented.

Results: Twenty three patients (15%) with rigid curves underwent osteotomies as part of their corrective surgery. Mean age in this cohort was 11.3 years (2–26), 35% were males, 65% females. In 17 of the patients the main deformity was scoliosis, in 5 – kyphosis and in – 1 lordosis. MMC was the leading underlying condition in 4 cases, followed by VACTER syndrome (2), congenital myopathy (2), arthrogryposis and pterygium (2), Neuro-blastoma (1) and other congenital conditions. Operative results were satisfactory in terms of cosmetics, alignment and function. In 3 cases (13%) complications were encountered, with 2 infections requiring debridement, (one requiring hardware removal) and 1 Neurofibromatosis patient undergoing her 8th surgical procedure, developing an intraoperative partial neurological injury with nearly full recovery.

Conclusions: Osteotomies are an important part of surgery in rigid spinal deformities. These deformities occur frequently in syndromatic children making peri-operative treatment more complex. Osteotomies facilitate better outcome in terms of correction, sagittal and coronal balance and cosmetics. These procedures are highly demanding technically. However, it is our opinion that adequate correction of rigid deformity with the benefit of spinal column shortening by way of osteotomy, is protective from significant neurological traction injuries that otherwise may occur.
