Objective: This study aims to compare the use of halo-gravity traction (HGT) with and without previous anterior release, in terms of curve reduction, for the treatment of pediatric severe spinal deformity. Methods: From 2010 to 2016, all patients treated with HGT prior to instrumentation for scoliosis and kyphoscoliosis were reviewed. They were assessed by deformity etiology, previous anterior release, instrumentation procedure used, traction protocol, major Cobb angle before traction, after the protocol, and after the instrumentation procedure. Twelve patients met these criteria and constituted the sample groups: Group I (n=7) with anterior release and Group II (n=5) without anterior release. Results: The average pre-traction major curve Cobb angles were 114.9o and 108.4º for Group I and II, respectively (P>0.05). After HGT, both groups achieved a significant reduction in curve angle (P<0.05). Group I presented an average Cobb angle of 95.0o after HGT, representing a 17.3% (19.8o) curve reduction. Group II presented a Cobb angle of 80.1o, representing a 25.2% (28.4o) curve reduction. The difference between the two groups in relation to the reduction of major curve after HGT was not statistically significant (P=0.073). After the surgical procedure, the correction achieved was significantly improved (P<0.05), without statistically significant difference between the two groups (P>0.05). No major HGT related complications were reported. Conclusions: Anterior release prior to HGT did not increase major curve correction after posterior surgery for severe pediatric idiopathic and syndromic scoliosis. HGT is an effective and safe technique, though it frequently presents minor and transitory complications. Level of Evidence III; Retrospective Comparative Study.
Introduction: Cape Verde is a middle-income country benefiting from a health agreement with Portugal. The purpose of this study is to conduct a cost-benefit analysis on the enablement of Cape Verde to perform total hip replacement.Material and Methods: We assessed records from the Orthopaedic Department of Baptista de Sousa Hospital and the Portuguese Directorate-General of Health regarding hip fracture with indication for total hip replacement and hip arthritis cases evacuated to Portugal. We also analysed the direct costs of the treatment, and hypothesised the costs of performing total hip replacement in Cape Verde. We then conducted a cost-benefit analysis.Results: From 2011 to 2016, 126 patients (135 hips) would have indication for total hip replacement if it was possible to do it in Cape Verde. The performance of the procedure in Cape Verde would have resulted in a global benefit of €80 644.08, and a benefit of €597.36/per patient.Discussion: Our analysis indicates that the enablement of Cape Verde to autonomously perform total hip replacement on patients with hip fracture and arthritis would have a positive financial return. Total costs were underestimated due to the impossibility to calculate indirect costs. Enabling Cape Verde to perform total hip replacement would provide the recommended treatment for patients and reduce the socio-psychological impact of evacuation. Conclusion: Enabling Cape Verde to perform total hip replacement would represent an expense reduction, and an improvement of the country’s quality of healthcare and autonomy.
Case: A 39-year-old woman, with bipolar disorder, suffered an eight-meter fall, resulting in dens and proximal and distal humeral fractures associated with migration of a 6cm humerus fragment to the left cervical region. There were no skin breaches on admission. Posterior instrumented C1-C2 fusion was performed along with proximal humerus stabilization through anterograde static nailing after removal and repositioning of the cervical migrated fragment. Conclusion: High-energy trauma significantly increases treatment complexity. Understanding injury mechanism is crucial to adequately diagnose undisclosed lesions that otherwise might go unnoticed. In cases of bone migration, a thorough debridement is advised to prevent heterotopic calcifications.
