Cementless Total Hip Replacement

SummaryA six-year-old, female, spayed Labrador Retriever was evaluated for progressive lameness of one year duration, ending in non-weight-bearing of the right hindlimb. The dog had a history of severe coxarthrosis of both hip joints, and had a HELICA hip pros-thesis implanted in the right hip 18 months before. On survey radiographs, the acetabular and femoral components appeared unstable, with a large void in the proximal femur and a lacy periosteal reaction on the trochanter. Arthrocentesis was performed to rule out septic loosening. As culture samples were negative, the dog underwent surgery. We report the successful revision of an unstable HELICA screw hip prosthesis with a Zurich cementless total hip replacement. The patient had a good clinical and radiological outcome seven months postoperatively.

Abstract Objective The aim of this study was to quantify the complications using the Zurich total hip replacement system in an initial series of cases performed by a single surgeon who had experience with other total hip replacement systems. Materials and Methods This was a retrospective study in which complications were classified as major if any treatment was needed or if the outcome was less than near-normal function. Complications that did not warrant treatment and that did not result in function that was inferior to near-normal were considered minor. Outcomes were assessed by radiographic review, physical examination, subjective gait evaluation or, in one case, by objective gait analysis. Bilateral total hip replacements were considered separate procedures. Results The first 21 procedures in 19 dogs performed by a single surgeon were included. The mean time to follow-up was 48 weeks (range: 8–120 weeks; standard deviation: 36 weeks). Two cases (of 21) experienced major complications including one dog with excess internal femoral rotation during weight bearing and one dog having luxation. One case (of 21) had a minor complication; femoral fracture in the presence of an intact bone plate that maintained alignment and healed without treatment. Clinical Significance A high rate of successful outcomes with few major complications can be obtained in the initial cases treated using the Zurich total hip replacement system for surgeons with prior experience with other total hip replacement systems.

Psoriatic Lesions

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.
