Community Care Administration of Spinal Deformities in the Brazilian Public Health System.

OBJECTIVE:: Underfunding of the surgical treatment of complex spinal deformities has been an important reason for the steadily growing waiting lists in publicly funded healthcare systems. The aim of this study is to characterize the management of the treatment of spinal deformities in the public healthcare system. METHODS:: A cross-sectional study of 60 patients with complex pediatric spinal deformities waiting for treatment in December 2013 was performed. The evaluated parameters were place of origin, waiting time until first assessment at a specialized spine care center, waiting time for the surgical treatment, and need for implants not reimbursed by the healthcare system. RESULTS:: Ninety-one percent of the patients lived in São Paulo State (33% from Ribeirão Preto - DRS XIII). Patients waited for 0.5 to 48.0 months for referral, and the waiting times for surgery ranged from 2 to 117 months. Forty-five percent of the patients required implants for the surgical procedure that were not available. CONCLUSION:: The current management of patients with spinal deformities in the public healthcare system does not provide adequate treatment for these patients in our region. They experience long waiting periods for referral and prolonged waiting times to receive surgical treatment; additionally, many of the necessary procedures are not reimbursed by the public healthcare system.

Association Between Lumbar Spine Sagittal Alignment and L4-L5 Disc Degeneration Among Asymptomatic Young Adults.

STUDY DESIGN: Cross-sectional observational study on the relationship between the degrees of disc degeneration and sagittal alignment in asymptomatic healthy individuals. OBJECTIVE: This study sought to determine whether the sagittal spine alignment subtype is related to the prevalence of lumbar disc degeneration. SUMMARY AND BACKGROUND DATA: Sagittal balance and spinopelvic parameters might be risk factors for disc degeneration. METHODS: A total of 70 asymptomatic participants (36 women and 34 men) without regular physical activity were categorized according to the four subtypes of sagittal alignment proposed by Roussouly. All participants underwent magnetic resonance imaging of the lumbar spine (1.5T) and panoramic radiography of the spine. The degree of disc degeneration was graded using T2-weighted images according to the Pfirrmann classification. Spinopelvic parameters and vertebral curvatures were measured on digital panoramic radiographs using Surgimap software. Interobserver analyses for the Pfirrmann classification and spinopelvic parameters were assessed using the weighted Kappa and intraclass correlation coefficient (ICC), respectively. RESULTS: The Kappa associated with disc degeneration classification was 0.79 (95% confidence intervals 0.72-0.87). The ICCs were excellent, with small confidence intervals for all spinopelvic parameters. The type II group (flat lordosis) showed a higher frequency of degenerated discs at L4-L5 (P = 0.03) than the type IV group (long and curved lumbar spine). No significant differences in disc degeneration were observed among the four subtypes at the other disc levels. We found a negative, moderate correlation between the spinopelvic parameters and the occurrence of disc degeneration in the type II group. CONCLUSION: The Roussouly subtype II sagittal alignment is significantly associated with disc degeneration at L4-L5 in asymptomatic young adults. Our results support the hypothesis that spinal sagittal alignment plays a role in early disc degeneration. LEVEL OF EVIDENCE: 3.

Calcific discitis in an adult patient with intravertebral migration and spontaneous remission.

Symptomatic disc calcifications have been reported, especially in the pediatric population, and remain of unknown etiology. Such a condition has been very rarely reported in adults. The aim of this paper is to present a case report of calcific discitis in an adult patient with intravertebral migration and spontaneous calcification resorption. The clinical presentation was that of back pain with an abrupt onset, not related to trauma or to physical activity. No fever or neurological deficits were present. Blood count, erythrocyte sedimentation rate, routine urine, and urine culture were negative. The pain regressed in 20 days with analgesic therapy. Findings of thoracic calcific discitis are illustrated with X-rays, CT, MRI, and bone scintigraphy.

OCCULT MANUBRIOSTERNAL JOINT INJURY ASSOCIATED WITH FRACTURE OF THE THORACIC SPINE.

The authors report the occurrence of an occult manubriosternal joint injury in the initial evaluation on a patient with a thoracic spine fracture (T9). This T9 fracture was diagnosed in a 37-year-old man and was associated with a partial neurological deficit. At the initial evaluation, the radiographs produced did not show the manubriosternal joint injury. During rehabilitation, after surgical stabilization of the thoracic spine fracture, the patient suddenly felt an intense pain accompanied by deformation at the sternal level. From imaging examinations, manubriosternal luxation was diagnosed. Because of recurrence of the luxation and the incapacitating pain, open reduction and fixation of the manubriosternal joint had to be performed. At the 12-month follow-up, the patient presented complete recovery of the neurological lesion, consolidation of the arthrodesis on the T7-T11 vertebral segment and maintenance of the reduction of the manubriosternal joint, which was asymptomatic during daily activities.

FUNCTIONAL AND RADIOGRAPHIC COMPARISON OF ANTERIOR AND POSTERIOR INSTRUMENTATION FOR THE CORRECTION OF ADOLESCENT IDIOPATHIC SCOLIOSIS.

OBJECTIVE: This was a retrospective study to compare the anterior instrumentation (AI) and posterior instrumentation (PI) results among patients diagnosed with adolescent idiopathic scoliosis (Lenke type I) who were treated surgically. METHODS: The results from 24 patients aged 11 to 18 years with Lenke type I idiopathic scoliosis who underwent surgery with AI (12 patients) or PI (12 patients) were compared. All the patients were operated by the same surgeon and were followed up for a minimum period of five years. The variables for comparison included: coronal and sagittal correction, distance from apical vertebra to midline, apical vertebral rotation, number of instrumented vertebrae and functional variables (by means of the SRS-22 questionnaire). The data obtained were analyzed using the SAS software, version 9. The two groups were compared using Student's t-test with a significance level of 5% (0.05). RESULTS: The correction of the curve in the frontal plane was higher in the group of patients with the anterior approach, in the immediate (p=0.031) and late (p=0.043) postoperative periods, as was the apical vertebral rotation during the immediate (p=0.002) and late (p=0.019) evaluations. The number of instrumented vertebrae was 7.69 ± 1.38 in the AI group and 11.38 ± 2.92 in the PI group (p = 0.021). Functional assessment (SRS-22) did not show any significant difference (p > 0.05) between the groups. CONCLUSION: The patients who underwent scoliosis correction with AI presented greater correction in the frontal plane, greater derotation of apical vertebrae and a smaller number of fused vertebrae.

EVALUATION OF TERMINAL VERTEBRAL PLATE ON CERVICAL SPINE AT DIFFERENT AGE GROUPS AND ITS CORRELATION WITH INTERVERTEBRAL DISC THICKNESS.

UNLABELLED: To evaluate, by means of histomorphometry, terminal vertebral plate thickness, intervertebral disc thickness and its correlation on different age groups, seeking to identify its correlation. METHODS: C4-C5 and C5-C6 cervical segments removed from human cadavers of both genders were assessed and divided into five groups of 10-year age intervals, from 21 years old. TVP and intervertebral disc thickness evaluation was made by means of histomorphometry of histological slides stained with hematoxylin and eosyn. Lower C4 TVP, upper C5 TVP, and upper C6 TVP de were compared between each other and to the interposed intervertebral disc thickness between relevant TVP. RESULTS: The thickness of terminal vertebral plates adjacent to the same ID did not show statistic differences. However, the comparison of upper and lower vertebral plates thickness on the same cervical vertebra (C5), showed statistical difference on all age groups studied. We found a statistical correlation coefficient above 80% between terminal vertebral plate and adjacent intervertebral disc, with a proportional thickness reduction of both structures on the different cervical levels studied, and also on the different age groups assessed. CONCLUSION: Terminal vertebral plate shows a morphologic correlation with the intervertebral disc next to it, and does not show correlation with the terminal vertebral plate on the same vertebra.

MULTIPLE SEGMENTAL OSTEOTOMIES TO THE KYPHOSIS CORRECTION.

OBJECTIVE: To evaluate the results of the surgical treatment of the spinal Kyphosis using the Ponte's technique (multiple posterior osteotomies). METHODS: Ten patients (8 with Scheuermann's kyphosis and 2 with kyphosis after laminectomy) submitted to surgical correction of kyphotic deformity greater than 70° were retrospectively assessed. The age at the surgical time ranged from 12 to 20 years old (mean age16.8 years ± 2.89). The radiographic parameters evaluated were the kyphosis, the lordosis and the scoliosis - whenever present. The presence of proximal and distal junctional kyphosis, loss of correction, and complications as implants loosening and breakage were also assessed. The radiographic parameters were evaluated at the preoperative, early postoperative and late postoperative time. RESULTS: The patients were followed through a period that ranged from 24 to 144 months (65.8 ±39.92). The mean value of the kyphosis was 78.8° ± 7.59° (Cobb) before surgery and 47.5° ± 12.54° at late follow up, with mean correction of 33.9° ± 9.53° and lost correction of 2.2°. CONCLUSION: The surgical treatment of the thoracic kyphosis using multiples posterior osteotomies presented a good correction of the deformity and minimal lost of correction during follow up.
