Book Description
Il s'agit d'une étude prospective comportant 54 fractures du col fémoral traitées par PTH à cotyle double mobilité impacté en press-fit. Il n'y a pas de critères d'exclusion en fonction de l'âge et du niveau d'autonomie. Le recul moyen de la revue clinique et radiologique est de 11,5 mois (9-15 mois). Aucun patient n'a été perdu de vue. 3 patients sont exclus secondairement devant l'impossibilité de placer un cotyle press-fit. 12 patients sont décédés au cours du suivi. Le traitement des fractures du col f2moral par PTH apporte les meilleurs résultats en termes de douleur et de mobilité aux patients. La double mobilité est une réponse adaptée au risque de luxation de PTH dans le traitement de la fracture du col fémoral après 70 ans y compris par voie postérieure.

Book Description
This volume is a comprehensive guide to the evaluation and treatment of failed total hip replacements. The book examines the mechanisms of hip arthroplasty failure -- particularly the mechanical properties and wear of polyethylene -- and describes the diagnostic workup of the painful hip arthroplasty. The indications and techniques for all current revision methods are described in detail and illustrated by over 400 photographs and drawings, many in full color. Coverage includes newer techniques such as impaction grafting and Prostalic components. Close attention is given to the technical aspects of the operative approach to all of the problems faced in revision surgery.

Book Description
The theme of this work is the application of the engmeermg theory of frictional torque to total hip replacement. The author adhered tenaciously to this theory, involving the use of a small-diameter femoral head, throughout the epoch when the large-diame ter, metal-to-metal design dominated the field. During that considerable period general satisfaction with the early results rendered criticisms of the large-diameter head unwelcome. There was a formidable array of counter criticism: the small head would pierce a film of synovial fluid; the small head would wear the socket too rapidly; the small head would always have a high risk of dislocation; detachment of the trochanter, to achieve precise orientation for the small head, was unacceptable. But all these objections have now been largely overcome. Lubrication of high molecular weight polyethylene (HMWP) on metal is now accepted as being mainly by the boundary regime with thick fluid films playing no part. We now know that HMWP can indeed tolerate the very high stresses imposed by the small head and in tribological theory there may even be some advantage in high stress. Dislocation is now known not to be an automatic sequel to the small head.

Book Description
Cerebral palsy presents stable encephalopathy that systemically influences on the child's and adult's organism. Orthopedic complications of cerebral palsy possess on the contrary progressive features and those complications cause gradual failure of motor ability of a person: impaired walking, loss of postural ability, reduced self-care and inclusion, finally quality of life becoming much worse. That is why orthopedic aspects are of great importance in children with cerebral palsy. This volume presents a collection of chapters covering a wide range of problems, from a system of universal classification of dysfunctions in Cerebral Palsy and practical issues of prevention of orthopedic complications orthopedic to surgery (diagnostics and quantitative interpretation of gait disorders in such patients, optimal methods of surgical intervention, hip surgery, spinal surgery) and aspects of nutritive status of this specific category of patients, associated comorbidities and their influence and connection with orthopedic problems. Furthermore, three chapters are dedicated to the anesthetic aspects of orthopedic surgery. The substantiation is given to the methods of combined anesthesia and sedation during surgery, as well as in the immediate postoperative period, taking into account concomitant epilepsy, increased intracranial pressure and spasticity in such children.Single-event multilevel orthopedic surgery is a recognized gold standard in ambulatory patients, though it varies according to gait patterns and associated orthopedic problems causing motor disorders. The book contains explanations and methodology of surgeries for conventional gait patterns, as well as in iatrogenic disorders caused by previous unreasonable interventions. The chapter on the correction of deformities and dysfunctions of the upper limb shows the first applied transfer of m.flexor cubitus ulnaris to the radius, which gave extremely positive results both in terms of function and aesthetics.Unfortunately, in Russia the number of CP patients with iatrogenic orthopedic disorders is high. Extremely negative consequences in the form of weakness of the triceps muscles after percutaneous fibromyotomies (so-called "Ulzibat method") or lengthening of the Achilles tendon in diplegia performed before the age of five years and before the development of muscle retraction lead to the development of crouch gait even in patients with high motor potential (GMFCS I, II). This complication of unreasonable surgical interventions develops in 5-7 years after primary surgery and in the opinion of doctors and parents is not related to previous procedures. This book, based on 3D-instrumented gait analysis, shows the features of iatrogenic crouch gait, as well as methods of surgical correction of this difficult situation.The data presented in this book are based, on the one hand, on the personal practical and scientific experience of each author, and on the other hand, the entire team of authors works in collaboration with each other, coordinating their decisions and interventions with colleagues, thus ensuring continuity in treatment of children and adults suffering from cerebral palsy.
