A new direction for EJOST

It is with great pleasure that we announce the promotion of Dr. Cyril Mauffrey as Editor in Chief of EJOST. This decision rewards the huge efforts and success of our recent indexation into Medline/PubMed. In addition, it gives a clear signal to our readers, authors and editorial board that we are aiming to strengthen our presence in the North American Market. From his position at Denver Health Medical Center and University of Colorado, his leadership of the research division and his professional contacts throughout several continents, Cyril will develop and strengthen the presence and importance of EJOST in the USA. This promotion will be announced by the following presentation on the first page of the print version and the electronic version of each issue of EJOST:

Synthesis of the 18th ArgoSpine Symposium

Abstract The subject of this 18th Symposium of ArgoSpine Association was the space of the intervertebral discs. Space of the intervertebral discs must be initially defined anatomically and histologically. A geometrical rebuilding in 3D is possible and must allow a modeling of the intervertebral discs. The physiology of the disc, its nutrition, must be known, in particular that of the center of the disc. The disc constitutes the base of the balance of the rachis, balances which can be only dynamic. The degenerative cascade by the loss of the proteoglycans involves the loss of the biomechanical properties of the disc. The consequences of this degenerative cascade are the base of all the vertebral pathology of origin of the intervertebral discs and even of the posterior articular facets. The origin of the pains and the diagnosis, especially at the lumbar level, are studied by the speakers. Traumatology of the intervertebral discs is the object of a particular chapter. Finally, the average therapeutic ones, that is, decompression of the intervertebral discs, fusion of the intervertebral discs, the recovery of mobility of the intervertebral discs, and the capacity of restoration of space of the intervertebral discs, are studied in detail. The infection of the disc is studied in detail.

Surgical treatment of lumbar degenerative scoliosis

Adult degenerative lumbar scoliosis is a subject today with functional problems like low back and root pain. In the past only the most severe deformities were operated, because of the risk of the intervention and the post-operative complications. Surgical treatment by the posterior approach with the rotation of the convex rod, gives normal anatomy without neurological risk. The instrumentation is strong enough to allow standing without brace or cast. An obvious advantage of this instrumentation is that it allows one to operate on scoliosis without restrictions due to age..

A career in orthopaedics

With a lot of commitment to their studies and an idyllic charm, enthused high school students succeed the School of Medicine. After 2 years in amphitheatre lessons, they finally begin clinical rotations. With emphasis on training and caring for patients, they willingly sacrifice a lot of personal hobbies and interests. They are motivated and enthusiast, often faced with pessimism for the future, and less often with inattention, cynicism and disregard. After a lot of sacrifices and stress, the medical students graduate the School of Medicine. Some graduate with honours and with a high scholastic talent, mechanical ability and manual dexterity, they decide to follow a career in orthopaedics and enter an orthopaedic training programme. During the orthopaedic residency programme, most residents are initially enthusiastic by the knowledge, expertise and judgment of their senior residents, professors and heads of departments. Little time exists outside hospital; amalgamated with the phobia of burnout, most of time is spent in hospital duties, auditoriums and seminars, or studying the bibliography, surgical approaches and techniques. Some residents form strong bonds with colleagues, consultants and professors and generate a dynamic synergy; some are blessed to be trained by experts, mentors and leaders. They are introduced to journals and international memberships; they are invited by prestigious editors and start reviewing and writing. These help to build the basis for a prolific career. The residents finally achieve orthopaedic licensure; some find caring for patients with cancer particularly rewarding and decide to pursue a fellowship in orthopaedic oncology; others are enthusiastic by trauma, shoulder or spinal surgery and have opted for a respective fellowship and subsequent practice [1]. At fellowships, they meet important people, build dynamic friendships, study hard and write a lot to share knowledge. Then, they meet wonderful people, prestigious editors from the international medical community; they introduce them to their journals and invite them to their reviewers’ panels and editorial boards. They help them “to stand on the shoulders of giants, to see more and farther than predecessors, not because of keener vision or greater height, but because they are lifted up and borne aloft on their gigantic stature” [2–4]. At the end of fellowship, they join a prestigious practice. However, the discipline is challenging, demanding, consuming and rewarding. Balancing personal and professional life is a common challenge for surgeons; family is often overlooked [5–9]. Financial success, international fame and recognition and personal interests/family are competing interests. Identifying personal values and protecting personal time are necessary to achieve work–life balance [1, 10–12]. Orthopaedics is a medical specialty that focuses on the diagnosis, care and therapy of patients with disorders and syndromes of the musculoskeletal system. Diagnostic methods and aetiological therapies of traumatic, nonphysiological and pathological syndromes, pharmacologic and prophylactic therapeutic policies and targeted therapeutic schemes synthesize an enthusiastic orthopaedic practice. A giant anode has occurred in European propaedeutics and academics in orthopaedics and & Andreas F. Mavrogenis afm@otenet.gr

Synthesis of the 19th ArgoSpine Symposium.

Abstract After a short introduction of the meeting by the President 2015, Wilco Peul, the opening lecture was delivered by Bart Koes, who dealt with Health Technology Assessment and Guidelines. Then, it was the turn of Carmen Vleggert to show whether there was any Evidence for the Use of Implants in Spinal Stenosis. The final presentation of this session was delivered by Björn Strömqvist who dealt with Surgery for Lumbar Disc Herniation, patients’ selection and outcomes. Developing the subject of “Do Not’s”, Jeremy Fairbank described the UK experience for Low Back Pain. Yves Coppens then took over and further elaborated on “Lucy’s legacy”. Prof. Coppens recalled that Lucy is a partial skeleton of a pre-human found in Ethiopia among other remains. Prof. Alan Crockard offered what he called “a whimsical view” of his practice of Craniocervical Surgery. Wafa Skalli was asked to speak about Finite Element Analysis of the Spine and Arts et Métiers Paris Tech where there is a long tradition of close collaboration between engineers and clinicians. Rune Hedlund, who will serve as 2016 Symposium President, further elaborated on Scoliosis with a focus on Unsolved Issues in Adolescent Idiopathic Scoliosis Treatment.

Synthesis of the 17th ArgoSpine symposium.

José Casamitjana opened this first symposium with a presentation on Dynamic Cervical Plates. He first introduced the principles of the different types of fusion in the cervical spine, depending notably on the importance of the quality of the bone. The aim of the plates is to avoid deformities, achieve stabilisation and to restore the profile of the patient. He noted that a rigid screw plate construct behaves as a rigid body, while a semi-rigid screw plate helps improve fusion over time. With dynamic plates, the screws are locked firmly to the bone. The defenders of this type of plates advocate Wolff’s law further completed by Harold Frost. Dr Casamitjana then described the mechanical behaviour of the different cervical plates. In semi-rigid plates, the screw moves inside the cancellous bone. Biomechanical studies concluded that graft loading increased with dynamic plates in 48–85 % of the cases. There was no clinical difference observed in fusion rates. In conclusion, Dr Casamitjana insisted on the importance of selecting the most appropriate bone graft. The second speaker, Dr Rousseau, replacing Cédric Barrey, addressed the biomechanics, kinematic concepts and motion preservation with cervical TDR. He described the different prostheses constraints (3, 5, 6 degrees of freedom implants), adding that the most recent ones (6) had no gliding surfaces. According to the literature, the median range of motion (ROM) of the physiological disc in normal population ranges between 15 and 21 at C4–C5, mostly in flexion/extension. The median amount of motion given by the prosthesis between the two vertebras is 5 (range 5 –9 ). The geometry of the implant has an influence on the mechanical behaviour with the possibility of kinematic conflicts. The location of the centre of rotation varies. Modelling is useful to study it into details, notably using dynamic EOS. The next step would be to go to instantaneous centre of rotation; the step ahead would be 3-DOF modelling. We are at the beginning of what we know and can describe, but we have tremendous tools to assess prostheses and patient parameters: anatomy, level and lordosis. Guy Matgé then addressed the indications and results of Dynamic Cervical Implants. The DCI philosophy is control of rotation and shock absorption in semi-constrained motion. The indications are no significant arthropathy; radiculopathy as well as adjacent segment degeneration. The surgical approach is a standard microtechnique, with decompression as large and as deep as possible.

MEDLINE and the European Journal of Orthopaedic Surgery and Traumatology

It is with great pride that our editorial board announces that the European Journal of Orthopaedic Surgery and Traumatology (EJOST) is indexed by the National Library of Medicine (NLM). This indexation opens the way for MEDLINE, the research engine powered by PubMed and the NLM. A publication indexed by MEDLINE is easy to find, easy to cite and easy to include in an electronic research software such as EndNote or Reference Manager. The road leading to this achievement started a decade ago with modification of our editorial board structure, a greater involvement of international reviewers and scientific committee panel members, higher quality research papers both on a clinical and on an ethical standpoint, modernization and timing of our reviewing process and most importantly, affiliation with new Orthopaedic societies. In the last 2 years, societies such as the Romanian, Serbian, Slovenian, the Chinese Hebei society, Pan Arabic and soon, the Brazilian Orthopaedic trauma society have joined our ship, choosing the European Journal of Orthopaedic Surgery and Traumatology (EJOST) as ‘their’ journal. We feel privileged to have such a broad spectrum of countries and associations putting trust in EJOST and hope that they feel that this victory is also theirs. We would also like to thank our readers and authors who, throughout the years, have send quality work. The level of their publication is certainly the most important factor in the decision process of the National Library of Medicine Panel to promote us to the very sought after ‘MEDLINE status’. This is now a new era for EJOST, one that will have an impact for all of us. First, the number of yearly submission will grow from the current hundreds to a few thousands. By the sole fact of being listed in MEDLIE, the reference of some of our publications will increase and our impact factor will creep up significantly. The advertisers will be more inclined to advertise their products in our journals with healthier revenue for our publishers. With more submissions, reviewers and editors will have to be more ‘picky’ and critical to reach an improvement in the quality of research published. Be confident that with the new indexation, our main focus will remain the service that we provide for our

Robert W. Bucholz, Charles M. Court-Brown, James D. Heckman, Paul Tornetta III (Eds.). Margaret M. McQueen, William M. Ricci (Ass. Eds.): Rockwood and Green’s fractures in adults, 7th edn

‘‘The encyclopedia par excellence of traumatology’’. This one is complete with precise descriptions since the diagnosis with classifications until the treatment while passing by the complications. Drawings and photographs unfortunately in black and white supplement each chapter. It is not a question, however, of a book of techniques. Practically, all the fractures are described as well upper limbs and inferiors that pelvis or column. At the beginning of the book, one finds the principles general of treatment of the fractures. Two characteristics of this book are interesting. A table of the various treatments with the respective advantages and disadvantages quickly makes it possible to have its idea and to choose ‘‘the good’’ treatment. In addition, the preferred method of the author enables him to personalize a chapter, when exists a list of possibilities and thus allows to support a way of doing which proved reliable. The bibliographies are very complete although very American. The access to Internet site makes it possible to have access to video-movies. This book is with being advised with all those which practice traumatology that it is senior or resident.
