Jiang S, Zheng K, Wang W, et al. - A retrospective epidemiological study was conducted to ascertain the incidence and factors associated with the occurrence of postoperative phantom limb pain (PLP), stump limb pain, and phantom limb sensations in tumor amputees within the first month after surgery. Researchers further evaluated differences in phantom phenomena between upper and lower extremities. Between 2012 and 2019, a total of 162 amputees participated in this retrospective study who had undergone malignant limb amputation. They used a numerical rating scale to evaluate phantom phenomena. They applied analysis of variance and non-parametric statistics for categorical variables and ordinal variables separately. The results revealed that proximal amputation and long-term preoperative pain seemed to count more for PLP incidence. There is a need for further study to ascertain factors correlated with the occurrence and chronicity of phantom phenomena.
