Resumo: | Objective: Determine whether a locking screw would limit the subsidence of the universal biological fixation hip femoral stem (BFX ®) under cyclic load and increase the rigidity, performance and failure properties of the construction. Material and method: Paired femurs implanted with a traditional rod or a locking rod (constructions) were loaded cyclically in walking, trotting and galloping loads, while the movements of the implant and bone were captured using kinematic markers and high-speed video. . Buildings were loaded to the fault to assess the mechanical properties of the fault. Results: The subsidence of the implant was greater (P = 0.037) for the traditional implant (4.19 mm) than the interlocked implant (0.78 mm) only after cyclical canter loading and cumulatively after cyclical walking, trotting and gallop (5.20 mm vs. 1.28 mm, P = 0.038). The yield and failure loads were higher (P = 0.029 and 0.002, respectively) for the interlocking rod construct (1155 N and 2337 N) than the traditional rod construct (816 N and 1405 N). The change in the version angle after cyclic loading was greater (P = 0.020) in the traditional implant (3.89 degrees) than in the interlocked implant (0.16 degrees), while the varus displacement of the nail in the failure was greater ( P = 0.008) for the blocking implant (1.5 degrees) than the traditional implant (0.17 degrees). Conclusion: The addition of a stabilizing screw improved the stability of the construction and limited subsidence of a BFX ® femoral stem. The use of the interlocked implant can decrease postoperative subsidence. However, the in vivo effects of the blocking screw on osseointegration, bone remodeling and protection against stress are unknown. |

Objective: Determinar se um parafuso de bloqueio limitaria a subsidência da haste femoral do quadril universal de fixação biológica (BFX ®) sob carga cíclica e aumentaria as propriedades de rigidez, rendimento e falha da construção. Material and method: Os fêmures emparelhados implantados com uma haste tradicional ou uma haste de bloqueio (construções) foram carregados ciclicamente em cargas de caminhada, trote e galope, enquanto os movimentos do implante e do osso foram capturados usando marcadores cinemáticos e vídeo em alta velocidade. As construções foram carregadas até a falha para avaliar as propriedades mecânicas da falha. Results: A subsidência do implante foi maior ( P = 0,037) para o implante tradicional (4,19 mm) do que o implante intertravado (0,78 mm) somente após carregamento cíclico de galope e cumulativamente após cargas cíclicas de caminhada, trote e galope (5,20 mm vs. 1,28 mm , P = 0,038). As cargas de rendimento e falha foram maiores ( P = 0,029 e 0,002, respectivamente) para o construto de haste intertravada (1155 N e 2337 N) do que o construto de haste tradicional (816 N e 1405 N). A alteração do ângulo de versão após a carga cíclica foi maior ( P = 0,020) no implante tradicional (3,89 graus) do que no implante intertravado (0,16 graus), enquanto o deslocamento em varo da haste na falha foi maior ( P = 0,008) para o implante de bloqueio (1,5 graus) do que o implante tradicional (0,17 graus). Conclusion: A adição de um parafuso estabilizador melhorou a estabilidade da construção e subsidência limitada de uma haste femoral BFX ® . O uso do implante intertravado pode diminuir a subsidência pós-operatória. No entanto, os efeitos in vivo do parafuso de bloqueio na osseointegração, remodelação óssea e proteção contra o estresse são desconhecidos.Specialized Dentistry Group2019-07-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://bjihs.emnuvens.com.br/bjihs/article/view/46Brazilian Journal of Implantology and Health Sciences ; Vol. 1 No. 2 (2019): July ; 34-57Brazilian Journal of Implantology and Health Sciences ; Vol. 1 Núm. 2 (2019): Julho; 34-57Brazilian Journal of Implantology and Health Sciences ; v. 1 n. 2 (2019): Julho; 34-572674-8169reponame:Brazilian Journal of Implantology and Health Sciencesinstname:Grupo de Odontologia Especializada (GOE)instacron:GOEporhttps://bjihs.emnuvens.com.br/bjihs/article/view/46/67https://bjihs.emnuvens.com.br/bjihs/article/view/46/68Copyright (c) 2019 Brazilian Journal of Implantology and Health Sciences info:eu-repo/semantics/openAccessFerreira Lemos, Antonio CarlosCorrêa Silva, Antônio Fernando 2020-05-11T16:50:34Zoai:ojs.bjihs.emnuvens.com.br:article/46Revistahttps://bjihs.emnuvens.com.br/bjihsONGhttps://bjihs.emnuvens.com.br/bjihs/oaijournal.bjihs@periodicosbrasil.com.br2674-81692674-8169opendoar:2020-05-11T16:50:34Brazilian Journal of Implantology and Health Sciences - Grupo de Odontologia Especializada (GOE)false |
