Imaging evaluation of nano-hydroxyapatite/polyamide 66 strut in cervical construction after 1-level corpectomy: a retrospective study of 520 patients

AbstractBackgroundThe application of nano-hydroxyapatite/polyamide 66(n-HA/PA66) struts has become reliable in anterior cervical corpectomy and fusion (ACCF) as a source of sufficient segmental stability. This was a retrospective and long-term imaging evaluation of the n-HA/PA66 strut in 1-level ACCF.MethodsThe patients between June 2006 and December 2014, who underwent 1-level ACCF using an n-HA/PA66 strut, were reviewed. The neurological status was assessed using the Japanese Orthopedic Association (JOA) score and axial pain was evaluated using a Visual Analogue Scale (VAS) score and the radiographic parameters were determined by X-ray and 3-D CT examinations when necessary for the evaluation of bone fusion using the Brantigan scale and imaging characteristics.ResultsA total of 520 patients underwent one-level ACCF, with a mean follow-up (FU) duration of 72.38  ± 24.56 months. The level of surgery was C4 in 58 cases, C5 in 173 cases, C6 in 208 cases, and C7 in 81 cases. According to the Brantigan scale, on X-ray examination, the bony fusion rate was observed to be 40%, 70%, 93%, and 98% at 3 months, 6 months, 1 year and the final FU. An interesti ng radiographic appearance of the bone graft growth pattern was classified into three types. 95% of the patients accounted for types a and b. No significant differences were observed in age, hospitalization duration, surgical haemorrhage volume, or fusion rate among the types except in the p...

The purpose of this retrospective study was to determine the most appropriate distal fusion level in terms of clinical results and radiological changes in Lenke 3C adolescent idiopathic scoliosis (AIS). Between June 2010 and May 2014, a total of 90 consecutive patients who underwent surgery for Lenke 3C AIS were divided into three groups as L2, L3, and L4 according to the fusion levels and compared in terms of functional and radiological outcomes. Patients were evaluated with Scoliosis Research Society 22 (SRS 22) and the Oswestry disability index (ODI) at the final follow-up. Preoperative standard posteroanterior and late...

Conclusion: Incidental findings on MRI of the spine are less common in the paediatric population than in the adult population. Nevertheless, careful clinical evaluation of paediatric patients with complaints of axial and radiating pain is necessary in order to determine the correlation between symptoms and imaging findings.Resumo Objetivo: Determinar a preval ência de achados incidentais em exames de ressonância magnética (RM) da coluna cervical, torácica e lombar em uma população pediátrica. Materiais e Métodos: Foram avaliados 190 exames de RM da coluna vertebral de p...

DISCUSSION: These findings suggest that the relationship between parent factors and long-term postoperative pain outcomes may be dependent on the child's symptom profile at baseline. Since there may be bidirectional relationships between parent and child factors, interventions to mitigate long-term pain should address child symptoms as well as parental factors.

ConclusionsIn younger patients, avoiding complications and improving patients ’ self-image were essential for substantial satisfaction levels. In older patients, revision, standing ability, as well as sagittal spinopelvic alignment restoration, were the key factors. Surgeons should consider the differences in goals of each patient.

Abstract BACKGROUND: In the literature, there are few papers on long-term results after brace treatment and there is no consensus on whether scoliotic curves stop progressing at skeletal maturity. To date the factors that could influence curve behaviour following bracing have not been fully determined. AIM: The aim of this study was to evaluate the results and the loss of the scoliotic curve correction in a cohort of patients treated with PASB brace during adolescence and to compare patient outcomes of under and over 30 Cobb degrees 10 years after brace removal. DESIGN: This is an observational controlle...

Authors: Vanreusel I, Maes S, De Wolf D, Van Berendoncks A Abstract Atrial septal defects (ASDs) are the third most common type of congenital heart diseases with ostium secundum defects (ASDsII) being responsible for approximately 75% of these defects. The treatment consists of either a transcatheter closure or a surgical intervention. The transcatheter approach offers a less invasive alternative for patients who fulfill anatomical and size criteria and is therefore increasingly used as the preferred primary intervention. As general anaesthesia is sometimes contra-indicated for some patients needing ASD or PFO clos...

The objective was to investigate the electromyographic activity of the lumbar multifidus (MF) muscle and longissimus thoracis muscle, along with their activity ratio (MF longissimus thoracis ratio), during quadruped stabilization exercise performed with neutral posture and with increased lumbar lordosis in patients with chronic low back pain (CLBP). A total of 23 patients with CLBP (12 females and 11 males) were recruited based on inclusion and exclusion criterion. Each patient performed 4 exercises in random order, with surface electromyography electrodes and an electrogoniometer attached. A cross-sectional study design w...
