Developmental Diseases of the Hip - Diagnosis and Management

There is a long list of diseases and traumatic events that affect hip joint, but none as persistent, as elusive and with profound consequences as developmental dysplasia. For many centuries, we have been struggling with its consequences while trying to understand the reasons how and why such a stable joint eventually becomes dysfunctional and how to prevent it. Some of the greatest achievements in operative orthopaedics have been introduced in the effort to treat developmental dysplasia of the hip. This book offers a contemporary approach to developmental dysplasia of the hip, covering various clinically relevant aspects - historical and epidemiological considerations, biomechanical analysis, conservative methods and operative treatment procedures. It is useful to have a quantitative measure of the contact hip stress and other relevant biomechanical parameters. Parameters that correlate with clinically relevant features are sought and relations between these parameters are studied. For this purpose, two different models for the resultant hip force in the one-legged stance (the primitive model and the HIPSTRESS model) are presented with which the effect of the shape of the pelvis and proximal femora is described. Also, a special case of the primitive model-the simple balance approximation-is considered. All three descriptions are based on the equilibrium of forces of torques and differ by increasing amount of information on the shape of the particular subject. It is shown in a case of normal hip and pelvis geometry that the primitive model gives similar values of biomechanical parameters as the HIPSTRESS model that was validated by clinical studies. The primitive model (but not the simple balance approximation) merits to minimal standards to be used for understanding of the principles of the equilibrium of the forces and torques in the one-legged stance and can in certain cases (such as the one shown) also yield a valid quantitative estimation of the biomechanical parameters Chapter 1 Introductory Chapter: Five-Dimensional Approach to the Developmental Dysplasia of the Hip 1 Chapter 2 Understanding Hip Biomechanics: From Simple Equilibrium to Personalized HIPSTRESS Method 15 Chapter 3 Developmental Dysplasia of the Hip in Childhood – Etiology, Diagnostics and Conservative Treatment 37 Chapter 4 Pelvic Osteotomies for Developmental Dysplasia of the Hip 51 Chapter 5 Total Hip Replacement in Developmental Dysplasia 75 Chapter 6 Total Hip Replacement in Developmental Dysplasia of the Hip: Pitfalls and Challenges 91 Спизжено у ExLib: avxhome.in/blogs/exLib Stole src from http://avxhome.in/blogs/exLib: tanas.olesya (avax); Snorgared,D3pZ4i & bhgvld,Denixxx (for softarchive) My gift to leosan (==leonadin GasGeo&BioMedLover from ru-board :-) - Lover to steal and edit someone else's Любителю пиздить и редактировать чужое Спизжено у ExLib: avxhome.in/blogs/exLib,Stole src from http://avxhome.in/blogs/exLib:,tanas.olesya (avax),Snorgared,D3pZ4i & bhgvld,Denixxx,(for softarchive),My gift to leosan (==leonadin GasGeo&BioMedLover from ru-board :-) - Lover to steal and edit someone else's,Любителю пиздить и редактировать чужое
