The purpose of this case report is to 1) briefly describe the traditional above-knee (AK) quadrilateral socket, 2) describe the contoured adducted trochanteric-controlled alignment method (CAT-CAM) socket, 3) describe the management of a patient with a temporary CAT-CAM prosthesis, and 4) explain how the CAT-CAM prosthesis approach has resolved a medically complex clinical problem. The 49-year-old patient in this case study received a left AK amputation in 1984 and was provided with a quadrilateral socket. She abandoned this prosthesis after 2 years because of her dissatisfaction with the device (ie, poor fit, awkwardness, excessive energy expenditure) and because of her compromised cardiac condition. The patient was fitted with a CAT-CAM prosthesis in 1988 and reported increased comfort, ease of donning and doffing, and increased gait efficiency with the CAT-CAM prosthesis as compared with the quadrilateral socket. The patient required 19 days of prosthetic training and was discharged independent in ambulation and transfers using two straight canes. We consider the CAT-CAM prosthesis an improvement over the quadrilateral socket for increasing ambulation independence in the individual with AK amputation and other medical complications.
1）简要描述传统的膝上（AK）四边形接受腔；2）描述轮廓化内收转子控制对线方法（CAT-CAM）接受腔；3）描述一名使用临时CAT-CAM假体患者的治疗情况；4）解释CAT-CAM假体方法如何解决了一个医学上复杂的临床问题。本病例研究中的49岁患者于1984年接受了左膝上截肢，并配备了四边形接受腔。两年后，她因对该装置不满意（即贴合度差、笨拙、能量消耗过多）以及心脏状况不佳而放弃了这个假体。该患者于1988年安装了CAT-CAM假体，并报告称与四边形接受腔相比，CAT-CAM假体的舒适度提高、穿脱更容易，步态效率也有所提高。该患者需要19天的假肢训练，出院时能够使用两根直手杖独立行走和转移。我们认为，对于增加膝上截肢及其他医学并发症患者的行走独立性而言，CAT-CAM假体比四边形接受腔有所改进。
