Abstract Aim Pain is a common post-operative complication after limb amputation. Though the evidence is mixed, current literature suggests nerve sheath catheters (NSC) have no effect on chronic stump pain, phantom limb pain or post-operative pain score but reduces opioid use. This study aims to compare pain outcomes in those with and without NSC after above knee amputations (AKA) and below knee amputations (BKA). Method This retrospective study collected information from 32 patients after lower-limb amputation from April 2014 - March 2017. Information regarding indication, anaesthetic and morphine requirement at 72 hours were collected from medical records and standardised questions used to assess phantom limb pain, chronic limb pain and pain intensity (1-10) at 24, 48 and 72 hours. Results Of the 11 patients who received a NSC catheter for pain control, 33% experienced no post-operative pain, 18% experienced phantom limb pain, 18% reported chronic limb pain and 62% required higher dosages of morphine at 72 hours. However, two patients used large amounts of morphine potentially giving spurious results. In comparison, of those patients without NCS, 43% experienced no pain, 9% experienced phantom limb pain, 33% reported chronic limb pain and only 47% required morphine at 72 hours and at lower doses compared to with NSC. The incidence of phantom limb pain was higher in those who had AKA regardless of the analgesic technique used. Conclusion Patients with NSC were less likely to experience chronic limb pain thus proving their role in post-operative pain control despite having higher morphine requirements.

Pain Mechanisms

Multimodal analgesia may include pharmacological components such as regional anesthesia, opioid and nonopioid systemic analgesics, nonsteroidal anti-inflammatories, and a variety of adjuvant agents. Multimodal analgesia has been reported for a variety of surgical procedures but not yet for lower limb amputation in vasculopathic patients. Perioperative pain management in these patients presents a particular challenge considering the multiple sources and pathways for acute and chronic pain that are involved, such as chronic ischemic limb pain, postoperative residual limb pain, coexisting musculoskeletal pain, phantom limb sensations, and chronic phantom limb pain. These pain mechanisms are explored and a proposed protocol for multimodal analgesia is outlined taking into account the common patient comorbidities found in this patient population.

Introduction. There is no diagnosis for phantom limb pain (PLP), and its investigation is based on anamnesis, which is subject to several biases. Therefore, it is important to describe and standardize the diagnostic methodology for PLP. Objective. To characterise PLP and, secondarily, to determine predictors for its diagnosis. Methodology. This is a cross-sectional study involving patients with unilateral traumatic lower-limb amputation aged over 18 years. Those with clinical decompensation or evidence of disease, trauma, or surgery in the central or peripheral nervous system were excluded. Sociodemographic and rehabilitative data were collected; PLP was characterised using the visual analogue scale (VAS), pain descriptors, and weekly frequency. Results. A total of 55 eligible patients participated in the study; most were male, young, above-knee amputees in the preprosthetic phase of the rehabilitation. The median PLP VAS was 60 (50–79.3) mm characterised by 13 (6–20) different descriptors in the same patient, which coexist, alternate, and add up to a frequency of 3.94 (2.5–4.38) times per week. The most frequent descriptor was movement of the phantom limb (70.91%). Tingling, numbness, flushing, itchiness, spasm, tremor, and throbbing are statistically significant PLP descriptor numbers per patient predicted by above-knee amputation, prosthetic phase, higher education level, and greater PLP intensity by VAS ( p < 0.05 ). Conclusion. PLP is not a single symptom, but a set with different sensations and perceptions that need directed and guided anamnesis for proper diagnosis.

The landmark paper discussed in this chapter, published by Bach et al. in 1988 is a Danish paper that describes a study where patients who were to undergo lower-limb amputation received either preventive, preoperative epidural analgesia for 72 hours before the amputation, or systemic analgesia. At 6 and 12 months post-operatively, all patients in the epidural group were pain free, while 38% and 27%, respectively, in the control group had phantom limb pain. The study has been criticized for a number of points including the pseudorandomization by year of birth, the lack of any blinding, and the small number of patients used in the study (only 25 patients overall).

BACKGROUND: Chronic pain is common in patients who undergo lower limb amputation. The use of epidural or perineural catheters seems to reduce acute pain after surgery but their effects in a longer follow up are unknown. OBJECTIVE: To evaluate the long-term prevalence of phantom limb sensation (PLS), phantom limb pain (PLP), and residual limb pain (RLP) and their correlation with perioperative use of epidural or perineural catheters. METHODS: Postal survey. Patients with trans-femoral, trans-tibial or hemi-pelvectomy amputation were asked to partake in the study. The Prosthetic Evaluation Questionnaire was used for the presence of chronic post-surgical pain. Presence of catheters was retrieved from medical notes. RESULTS: 57 patients at a mean of 4.4 years follow up were included. PLS was reported in 68.4%, PLP in 63.2 % and RLP in 54.4% of amputees. No correlation was identified between pain syndromes and the presence of individual catheters and the duration of their permanence. The simultaneous use of 2 catheters was related to a lesser presence of PLP. CONCLUSIONS: Data on prevalence of PLP, PLS and RLP are consistent with the literature. Favourable effects in PLP reduction in the long term follow up was related to the simultaneous use of two catheters.

Background Phantom limb pain (PLP) is a common and in some cases debilitating consequence of upper- or lower-limb amputation for which current treatments are inadequate. Objective This small clinical trial tested whether game-like interactions with immersive VR activities can reduce PLP in subjects with transtibial lower-limb amputation. Methods Seven participants attended 5–7 sessions in which they engaged in a visually immersive virtual reality experience that did not require leg movements (Cool! TM), followed by 10–12 sessions of targeted lower-limb VR treatment consisting of custom games requiring leg movement. In the latter condition, they controlled an avatar with 2 intact legs viewed in a head-mounted display (HTC Vive TM). A motion-tracking system mounted on the intact and residual limbs controlled the movements of both virtual extremities independently. Results All participants except one experienced a reduction of pain immediately after VR sessions, and their pre session pain levels also decreased over the course of the study. At a group level, PLP decreased by 28% after the treatment that did not include leg movements and 39.6% after the games requiring leg motions. Both treatments were successful in reducing PLP. Conclusions This VR intervention appears to be an efficacious treatment for PLP in subjects with lower-limb amputation.
