Abstract：
Luxation of the psittacine femorotibial joint most commonly occurs following trauma or as a development abnormality. Historically, this injury is considered to have a poor prognosis in birds; however, surgical management may result in acceptable and functional outcomes. This case series describes the surgical techniques, complications, and outcomes of 7 cases of femorotibial luxation in psittacine birds. Of the 7 cases, 6 were chronic injuries. Surgical repair methods included conjoined intramedullary pinning, transarticular pinning with an external skeletal fixator (ESF), a combination of extracapsular stabilization and ESF, ESF alone, and a combination of conjoined intramedullary pins with an ESF. An acceptable outcome was achieved in 75% (6/8) of luxated femorotibial joints managed with surgical methods. All cases were female birds of various species, suggesting a possible sex predisposition for stifle luxation.
摘要：
psittacine股胫关节的脱位最常见于创伤后或发育异常。历史上,这种伤害被认为在鸟类中预后不良；然而，手术治疗可能会产生可接受的功能结局.这个案例系列描述了手术技术，并发症,和7例股胫脱位的结果。在这7个案例中,6是慢性损伤。手术修复方法包括连体髓内钉扎，与外部骨骼固定器（ESF）的经关节固定，囊外稳定和ESF的组合，只有ESF，以及髓内钉与ESF的组合。通过手术方法管理的75％（6/8）的股胫关节脱位获得了可接受的结果。所有病例都是不同种类的雌鸟，提示窒息性脱位的可能性倾向。
