The aims of spinal deformity surgery are to achieve balance, relieve pain and prevent recurrence or worsening of the deformity.The main types of osteotomies are the Smith-Petersen osteotomy (SPO), pedicle subtraction osteotomy (PSO), bone-disc-bone osteotomy (BDBO) and vertebral column resection (VCR), in order of increasing complexity.SPO is a posterior column osteotomy in which the posterior ligaments and the facet joints are removed and correction is performed through the disc space. A mobile anterior disc is essential. SPO is best in patients with +6-8 cm C7 plumbline. The amount of correction is 9.3° to 10.7°/level (1°/mm bone).PSO is a technique where the posterior elements and pedicles are removed. Then a triangular wedge through the pedicles is removed and the posterior spine is shortened using the anterior cortex as a hinge. The ideal candidates are patients with a severe sagittal imbalance. A single level osteotomy can produce 30° 40° of correction. A single level osteotomy may restore global sagittal balance by an average of 9 cm with an upper limit of 19 cm.BDBO is an osteotomy done above and below a disc level. A BDBO provides correction rates in the range of 35° to 60°. The main indications are deformities with the disc space as the apex and severe sagittal plane deformities.VCR is indicated for rigid multi-planar deformities, sharp angulated deformities, hemivertebra resections, resectable spinal tumours, post-traumatic deformities and spondyloptosis. The main indication for a VCR is fixed coronal plane deformity.The type of osteotomy must be chosen mainly according to the aetiology, type and apex of the deformity. One may start with SPOs and may gradually advance to complex osteotomies.Cite this article: EFORT Open Rev 2017;2:73-82.DOI: 10.1302/2058-5241.2.160069
Femoral shaft fractures are the most common pediatric injuries that require hospitalization. Early closed reduction and spica casting are one of the most popular treatment options. One of the significant complications of spica casting is rotational deformities of the fracture. The present study aimed to determine the potential effects of rotational deformities in pediatric patients who underwent early spica casting after a femoral shaft fracture. Pediatric patients who underwent early spica casting following femoral shaft fractures were screened retrospectively. Radiological measurements were made on the patients' initial postop radiographs who could be measured rotationally according to the defined radiological method. Twenty-three patients with more than 10° of rotation in their measurements were included in the study. Differences in leg length and rotation between both legs were calculated with clinical examination methods for all patients in the study. The gaits of the patients were observed; patient and family complaints were obtained. We found a strong and positive correlation between the rotational measurement made on the X-ray and the clinical measurement (R: 0.634, P: 0.001). For measurements made on X-ray, the mean rotational value was calculated as 27.2 ± 6.9 degrees. After the patients' clinical examination, an average of 3.0 ± 1.7 degrees rotational difference was found between the broken limb and the healthy limb. No patient or family complained of trauma. Early spica casting, according to the age of the patient, is an effective treatment method. There may still be certain degrees of deformity after treatment, but patients well tolerate them even at high degrees. Accordingly, it was concluded that the rotational deformities less than 30 degrees would not cause clinical problems on children under 4 years of age which may require postoperative revisions or the use of various costly imaging techniques and include radiation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
