Complications of surgical treatment of idiopathic scoliosis in adolescents

Introduction. In modern literature, there are still debates on causes of the most common complications after surgeries for idiopathic scoliosis in adolescents and their risk factors. Currently, there are growing potentials to reduce the length of patients’ postoperative stay in hospitals, but it arises the need for attending physicians to know better the main types of complications of juvenile idiopathic scoliosis after surgery, their risk factors so as to predict and avoid them, to develop an individual program for patient’s management in the postoperative period, especially for patients from the risk group.Material and methods. Literature search was done in databases Pubmed, Medline, Google Scholar, using key words, on complications of surgical correction of juvenile idiopathic scoliosis.Results. On analyzing the obtained literature data, two large groups of postoperative complications were described in details: somatic and neurological. In addition to most common complications, some rare ones are described too which include superior mesenteric artery syndrome and distant deep infections.Conclusion. Over the past twenty years, the incidence of postoperative complications after surgical correction of scoliotic deformities has significantly decreased. When analyzing findings of various trials, it can be concluded that the overall complication rate decreased in 2004-2007 from 5.7% (2000-2003) to 4.95% and then to 0.98% (2013-2016). Despite the general decrease in the incidence of complications, the latter still remain a problem for clinicians. The basic risk factors for such complications are: concomitant renal pathology, large volume of surgical blood loss, significant increase of exposure to anesthesia and surgical intervention, application of stainless steel constructions, anterior or combined surgical access, refusal of intraoperative neuromonitoring.

Neuman Systems Model in perioperative nursing care for adolescents with juvenile idiopathic scoliosis

ABSTRACT Objective: To implement the nursing process, based on the Neuman Systems Model and the International Classification of Nursing Practice terminology, in the care of an adolescent who underwent corrective surgery for juvenile idiopathic scoliosis. Method: This is a qualitative study of the type of single case, with triangulation of data collection techniques (formal clinical interview, notes in a field diary and medical record information), developed with a 17-year-old adolescent and indication for corrective surgery. The empirical materials generated with the interviews carried out at admission and at discharge, observation and medical record information were treated with categorical content analysis. Results: The categories of personal condition, anxiety, selfconcept, meaningful people, facilitating health resources, school, free time and leisure were recurrent. Diagnoses were defined with a focus on Anxiety, Knowledge on pain management (control) and Willingness (or readiness) to learn, associating them with the respective nursing interventions. Conclusion: The Model contributed to assess and recognize surgery stressors for the adolescent and to theoretically base the nursing process. The classification allowed systematizing nursing care records, elements of clinical practice, unifying vocabulary and codes.

Particular neurophysiological aspects of etiopathogenesis of juvenile idiopathic scoliosis

Aim. To study the data of mathematical model of mismatch between the vertebral length and the spinal cord calculated length in adolescents with juvenile idiopathic scoliosis. Materials and methods. The paper presents the data on the calculated value of spinal cord and vertebral growth mismatch coefficient according to computed optic tomography and transcranial magnetic stimulation data in 46 adolescents, suffering from multiplane vertebral deformity of different degree of severity. Results. The obtained data confirm the theory of mismatch between the spinal cord and vertebral growth. It was shown that spinal cord growth is the process, which does not depend on patients age and length of vertebral column. Conclusions. There was constructed a mathematical 3D-model of link between the multiplane deformity severity, age and spinal cord and vertebral growth mismatch coefficient value, which can serve as a perceptive prognostic instrument in diagnosis of idiopathic scoliosis.

Posterior Spinal Fusion Extended to Stable Vertebra Provides Similar Outcome in Juvenile Idiopathic Scoliosis Patients Compared with Adolescents with Fusion to the Touched Vertebra

Background and Aims: To compare outcomes between posterior spinal fusion of juvenile idiopathic scoliosis and adolescent idiopathic scoliosis patients with a minimum of 2-year follow-up. The juvenile idiopathic scoliosis patients were fused to the stable vertebra and adolescent idiopathic scoliosis to the touched vertebra. We hypothesized that extending the spinal fusion to the stable vertebra in juvenile patients would provide similar outcomes compared with fusion to the touched vertebra in adolescents. Materials and Methods: A prospective comparative study of 21 consecutive children with juvenile (Risser 0) and 84 adolescent (Risser ⩾2) idiopathic scoliosis (1:4 ratio) undergoing bilateral segmental pedicle screw instrumentation and direct vertebral derotation with a minimum of 2-year follow-up. Results: Juvenile patients had a significantly larger main curve (58° vs 53°, p = 0.003), more fused levels (p = 0.012) and posterior column osteotomies (p = 0.014) than adolescent patients. Distal adding-on (>10°) was observed in one (4.7%) juvenile and three (3.6%) adolescent patients (p = 0.80), without the need for revisions. Scoliosis Research Society 24 total score averaged 101 in juvenile and 97 in adolescent group at 2-year follow-up (p = 0.047). Conclusion: Posterior spinal fusion with bilateral segmental pedicle screw instrumentation to the stable vertebra provides similar clinical and radiographic outcomes in juvenile patients as compared with adolescents with fusion to the touched vertebra in idiopathic scoliosis. Health-related quality of life as measured using the Scoliosis Research Society 24 questionnaire at the end of follow-up was better in the juvenile as compared with the adolescent group.
