Conception for the choice of total hip replacement variant in adult patients with dysplastic coxarthrosis is presented. Criteria for the choice are interrelation of hip joint elements that is evaluated according to the femoral head coverage index elaborated by the authors. The conception was used in 126 patients (136 joints). Advantages of two-steps treatment of dysplastic coxarthrosis were detected: correction of joint elements correlation (pelvic osteotomy by Hiarу) at early stages of pathologic process and subsequent joint replacement at the terminal stage.

The major complications following total hip replacement (THA) are implant loosening, dislocation, instability, fracture and infection. It is hypothesized that vibration, in the range of the resonance frequencies, may cause pain, bone degeneration and fracture. A further understanding of the physical response resulting from impact during femoral head sliding may lead to valuable insight pertaining to THA failure. Therefore, the first objective of this present study was to determine if frequencies propagating through the hip joint near resonant frequencies may lead to wear or loosening of the components. Recently, studies found that femoral head sliding, often referred to as hip separation, between the acetabulum cup and the femoral head does occur, which may also play a role in complications observed with THA today, but a the effects of hip separation and the causes of its occurrence has not been studied as jet. Therefore, the second objective of this study was to determine if a sound sensor, externally attached, could be used to correlate impact loading sounds from femoral head sliding in the acetabular cup. Additional objective of this study was to develop a mathematical model that better simulates the in vivo loading conditions of total hip replacement patients using in vivo fluoroscopic and ground reaction data as input.

Background: Ceramics are inorganic nonmetallic materials and are used as bioinert components in joint replacement surgeries. Ceramics are known to be low allergenic. We experienced a ceramic-induced psoriasis. Objective: We report a first case of possible ceramic-induced psoriasis caused by a ceramic insert. Methods: A 55-year-old female received an implanted ceramic-on-ceramic total hip replacement for osteoarthritis of the right hip joint. Following surgery, she developed psoriatic lesions, which continued for 10 years. We suspected that psoriasis was caused by a ceramic insert and removed it surgically. Results: When the ceramic insert was replaced with a polyethylene-on-metal hip joint, the psoriatic lesions completely disappeared. Conclusion: The pathogenesis of psoriasis is still an enigma, although deregulation of nuclear factor κB signaling and resulting abnormal cytokine secretion are speculated to be involved. Ceramics may affect these signaling events and cause the onset of psoriasis. Renseignements de base: Les céramiques sont des matériaux non métalliques inorganiques et sont utilisées comme composants bio-inertes dans les arthroplasties. Les céramiques sont reconnues pour être peu allergisantes. Nous avons observé un psoriasis provoqué par la céramique. Objectif: Nous exposons un premier cas possible de psoriasis provoqué par la céramique causé par un implant en céramique. Méthodes: Une femme de 55 ans a reçu une prothèse céramique-sur-céramique implantée lors d'une arthroplastie totale de la hanche pour traiter l'arthrose de l'articulation de la hanche droite. Après la chirurgie, elle a développé des lésions psoriasiques dont la manifestation s'est poursuivie pendant 10 ans. Nous avons soupçonné que le psoriasis était causé par l'implant en céramique, et nous l'avons enlevé chirurgicalement. Résultats: Une fois l'implant en céramique remplacé par une prothèse articulaire en polyéthylène-sur-métal, les lésions psoriasiques ont disparu complètement. Conclusion: La pathogenèse du psoriasis demeure une énigme, bien qu'on suppose que la dérégulation de la voie de signalisation NF-κB et que la sécrétion anormale de cytokines résultante soient impliquées. Les céramiques peuvent affecter ces événements de signalisation et provoquer l'apparition du psoriasis.

Acetabulum malunions are extremely difficult to treat, and for many years, surgical indications have been dominated by total hip replacement. We treated a protruding acetabular malunion, 20 years ago, using an intra-articular buttress, by means of an allograft corresponding to a femoral head fragment which had been cryopreserved. The radiological and clinical result with this extended follow-up is quite remarkable, which has motivated us to present this original technique.

Bone marrow edema is a sign that can be accompanied with osteonecrosis of the femoral head. There is still controversy as to whether it is a reversible form of avascular necrosis or it is a disease entity of its own. The probability and extent of the edema correlate well with the pain and stage of the necrosis. Unlike transient osteoporosis of the hip and regional migratory osteoporosis which are spontaneously resolving conditions, osteonecrosis can cause significant changes in the hip joint. We present a case of a displaced fracture of the femoral neck complicating bone marrow edema in osteonecrosis of the femoral head, in a 42-year-old man, treated with a cementless total hip replacement. This case emphasizes a potential complication associated with the state of diffuse bone marrow edema of the hip.
