Postmortem examination revealed severe bone deformities involving the fractured humerus, both ulnas, and the left tibiotarsus.
Lesions comprised a moth-eaten pattern of lysis affecting mainly the medullary cavities; expansion and irregular contour of the cortex of the diaphysis and the metaphysis of the left radius and ulna, as well as, to a minor degree, the distal right ulna; irregular thinning with multifocal areas of subperiosteal scalloping and lysis of the cortex of both radiuses, ulnas, and tibiotarsi, as well as digits; irregular and poorly mineralized periosteal reaction on the medial aspect of the distal metaphysis and distal diaphysis of the left tibiotarsus; medullary sclerosis, geographic lysis, and multifocal subperiosteal scalloping without cortical expansion of both humeri; and an oblique, simple, and proximomedially displaced right humeral fracture (Fig 1).
Em outra pesquisa, foi observado que a terapia ultra-sonica, aplicada durante 20 minutos diarios, por periodos de 15, 30, 60 e 90 dias, nao promoveu a consolidacao ossea em ulnas de caes submetidos a ostectomias com 7mm de falha ossea (SILVA, 1990).
Os mecanismos de acao sugeridos para justificar a estimulacao ultra-sonica da formacao do calo osseo incluem a piezoeletricidade (DUARTE, 1983), o aumento da incorporacao de ions de calcio em culturas de osteoblastos e condrocitos (RYABY et al., 1989), estimulo a expressao de proteina agregadora de matriz extracelular (YANG et al., 1996), estimulo a sintese de fatores de crescimento (MASAYA et al., 2000) e influencia sobre reacoes celulares envolvidas na consolidacao ossea (AZUMA et al., 2001), alem de aumento da vascularizacao no sitio de osteotomias em ulna de caes tratados por ultra-som de baixa intensidade (RAWOOL et al., 2003).
Twelve matched pairs (left and right) of formalin-fixed cadaveric ulnas were stripped of all soft tissue and periosteum and divided into two groups of six pairs each (12 ulnae per group).
Objective: Determine contributions of plate length and locked fixation in an ulna fracture.
De estos, 30 eran humeros, 30 ulnas y 30 radios, la mitad de ellos correspondia al lado izquierdo y los restantes al lado derecho.
RESUMEN: La ubicacion de los foramenes nutricios en los huesos humero, ulna y radio ha sido descrita de forma general.
There are few scientific studies on the anatomy of the Saguinus leucopus (Stevenson et al., 2010), although recently the elements of the gross anatomy of the radius and humerus in relation to the function of their bone prominences for muscles and ligaments fixation and for articulation with adjacent bones (Duque-Parra et al., 2014; Duque-Parra & Velez-Garcia, 2014) like the ulna have been described.
The bones and joints are arranged as levers, hence, they can be moved by the muscles, which also allow the muscles have to be attached in the bones as they do in the ulna, which provides attachments to muscles that allow different movements at the elbow, carpus and digits (Standring, 2008; Dyce et al., 2012; Moore et al., 2013).
In each bird, a 1-cm critical size defect (CSD) was created in the left ulna, and the fracture was stabilized with external skeletal fixation (ESF).
