This paper presents the application of a low-cost 3D printing technology in pre-operative planning and intra-operative decision-making. Starting from Computed Tomography (CT) scans, we were able to reconstruct model area interest with very simple rapid workflow, using open-source software an entry level printer. The use High Temperature Poly-Lactic Acid (HTPLA) by ProtoPasta allowed fabricating sterilizable models, which could be used within surgical field. We believe that our method is...
This work aims to present an in-house low-cost computer-aided simulation (CASS) process that was recently implemented in the preoperative planning of complex osteotomies for limb deformities children. Five patients admitted Unit Paediatric Orthopaedics and Traumatology from April 2018 December 2019, correcting congenital or post-traumatic were included study. Three-dimensional (3D) digital models generated Computed Tomography (CT) scans, using free open-source software, surgery planned...
This paper presents a novel alghorithm of diagnosis and treatment rigid flatfoot due to tarsal coalition. It introduces workflow based on 3D printed models, that ensures more efficiency, not only by reducing costs time, but also improving procedures in the preoperative clinical phase. Since this concerns development new methodology integrates both engineering medical fields, it highlights symmetry. An economic comparison is made between traditional method innovative one; results demonstrate...
Early onset scoliosis (EOS) surgery based on growing spinal implants can lead to several complications. Aim of the study was identify strategies prevent those A retrospective review conducted all pediatric patients affected by EOS surgically treated with rod or Vertical Expandable Prosthetic Titanium Rib (VEPTR) at our division between 2006 and 2011. Nineteen consecutive (8 males, 11 females; mean age 6.8 years) were included. The was: idiopathic in 7 cases, congenital 5, associated heart...
The reported incidence of scoliosis in arthrogryposis varies from 30% to 67% and, most cases, the curves progress rapidly and become stiff early age.The authors report six cases assess role surgical treatment.Six (3 males, 3 females; mean age at surgery 13.2 years) with multiplex congenita associated characteristic amyoplasia were reviewed: they operated on for authors' Spine Surgery Department between 1987 2008.Surgery was performed using Harrington-Luque instrumentation (2 cases), Luque...
Our purpose is to develop the preoperative diagnosis stage for orthopedic surgical treatments using additive manufacturing technology. methods involve fast implementations of an manufactured bone model, converted from CAT data, through appropriate software use. Then, formed surfaces special 3D-printers. With structural model redesigned and printed in three dimensions, surgeon able look at he can handle it because perfectly reproduces real one upon which will operate. We found that models...
41 consecutive patients surgically treated at Our Department by posterior only instrumented fusion from January 1995 to 2009 were reviewed. There 20 females and 21 males with a mean age of 15.8 years (range, 10 38). Diagnosis was: cerebral palsy (13 cases), Duchenne muscular dystrophy (7), spinal amyotrophy myelomeningocele (5), poliomyelitis (3), Friedreich's ataxia (2), Escobar syndrome Steinert's disease (1), Charcot Marie Tooth (1). Main scoliosis Cobb angle averaged 94.05°...
Background Magnetically controlled growing rods (MCGR) are increasingly used for the treatment of early onset scoliosis. Aim study is to retrospectively review our patients treated with MCGR focusing on complications. Materials and methods We reviewed 7 patients, affected by scoliosis surgically magnetically (minimum follow up 6 months). There were children, 3 females 4 males, an age ranging from 11 years. The aetiology was idiopathic (infantile or juvenile), 1 congenital. In one case a...
Fused Deposition Modeling (FDM) 3D printing technology has widespread in a variety of scientific fields, since rapid prototyping and low-cost investments well meet flexibility application.Mechanical engineering is taking an essential role Orthopaedics Traumatology.As patient-specific approach minimally invasive surgeries are progressively needed today's medical routines, highly-customized printed devices surgical instruments represent milestone equipment.Virtual preoperatory planning...
This is a retrospective study of 11 patients, 7 females and 4 males, treated at Our Department for an early onset scoliosis (EOS) associated with rare syndromes growing spinal implants (Growing Rod or VEPTR-like) from 2006 to 2011. Mean follow-up was 24 months (range, 12 36). The mean age surgery 7. Patients were affected by Escobar's syndrome (1), congenital heart disease Arnold Chiari type 1 syringomyelia NF (2), Prader-Willi trisomy 8 arthrogryposis (2) spondylo-rib dysplasia (1). Each...
Study Design: Retrospective mini case series, single centre. Objective: To report the efficacy of growing spine distraction-based implants in treatment hyperkyphotic and kyphoscoliotic early-onset deformities during initial surgery lengthening. Background: Growth-sparing implants, such as rod VEPTR-like systems, are systems involving repetitive lengthening procedures, which mean that hyperkyphosis may be a relative contraindication early onset deformities. The role coronal is now...
Background Retrospective review of 62 consecutive patients affected by AIS (Lenke type 1 or 2) treated posterior fusion with pedicle screw-only instrumentation. Three groups identified: Pre-Rod (direct derotation procedure done before inserting rods), Single-Rod (derotation after concave rod insertion) Double-Rod (after both rods). The Pre-Rods insertion cases showed a significantly better final correction apical vertebral rotation (61.9% vs 55.8% and 50.1%) greater main thoracic curve....
This work is the outcome of a partnership between Department Industrial Engineering University Bologna and Rizzoli Orthopedic Institute Bologna.The aim this collaboration using medical engineering tools during orthopedic surgeries.This article focuses on design construction custom-made surgical guide for cubitus varus.The guides are special aids that allow surgeons to perform operations smoothly, achieve planned result reduce risk inaccuracy.They obtained with an additive manufacturing...
The association between Neurofibromatosis type I (NF1) and multiple myeloma (MM), a plasma cell, dyscrasia is very rare. Here we put to the attention of scientific community two new cases. first one patient with active MM whereas second smoldering MM. Both patients present typical features NF1 but skeletal alterations were only in case including dysplasia, marked scoliosis osteoporosis. osteolytic lesions absent both patients. In addition clinical diagnosis NF1, molecular testing for gene...
Materials and methods We retrospectively reviewed 16 paediatric patients affected by kyphotic spinal deformity (T3-T12 kyphosys > 60°) surgically treated with Growing Rod or VEPTR-like systems from 2006 to 2011. There were 8 males females, a mean age of 7 years (range, 4 11). The aetiology was: idiopathic scoliosis (5 cases), kyphosis in Morquio disease (1) Pott (1), congenital (3), trisomy Escobar syndrome Prader Willi spondylocostal dysplasia arthrogryposis (2). Dual growing rod was...
Materials and methods 78 consecutive patients (63 women 15 men) were included in the study, mean age of 66 years (range 60-77), surgically treated at our Division between 2000 2005.
