Eight transtibial amputees had localized unremitting discomfort and pain in the distal anterior residual limb during prosthetic wear while weightbearing. Modification of the prosthetic socket did not change this pain. It was not consistent with "phantom limb" or causalgia/reflex sympathetic dystrophy-type etiologies. Thirteen randomly selected, pain-free, transtibial amputees were selected for comparison. The subjects in both groups used similar total-contact, "patellar tendon-bearing" prosthetic sockets fabricated and aligned with similar technique. The angles formed between the femur and tibia, femur and prosthetic socket, and tibia and socket were measured. Significant differences were found at each angle measurement between those patients who experienced pain and those who did not. The variable of tibia length had no effect. We conclude that bone alignment within the transtibial total-contact prosthetic socket may be partially dependent on surgical technique and not solely on prosthetic socket configuration.
八名经胫骨截肢者在佩戴假肢负重时,残肢远端前侧出现局部持续不适和疼痛。假肢接受腔的修改并未改变这种疼痛。它与“幻肢”或灼痛/反射性交感神经营养不良型病因不符。随机挑选了13名无疼痛的经胫骨截肢者作为对照组。两组受试者均使用了采用相似技术制作和调整的类似全接触式“髌腱承重”假肢接受腔。测量了股骨与胫骨、股骨与假肢接受腔、胫骨与接受腔之间形成的角度。在经历疼痛的患者和未经历疼痛的患者之间,每次角度测量均发现显著差异。胫骨长度变量没有影响。我们得出结论,经胫骨全接触假肢接受腔内的骨骼对线可能部分取决于手术技术,而不仅仅取决于假肢接受腔的构型。
