The difficulty of choosing the method of analgesia after total replacement of the lower limb large joints (case report, literature review)

Abstract

A case of successful treatment of a patient with a periprosthetic fracture of the femur is described. The fracture occurred one day after total hip replacement as a result of a fall, possibly associated with postoperative conduction analgesia. Lower limb large joints total replacement may become the most frequently performed type of elective surgery already in the current decade. The increasing prevalence of osteoporosis, osteoarthritis, rheumatic diseases and hip fractures is an objective prerequisite for it. Despite of all efforts, the problem of postoperative pain control during these surgical interventions currently remains unresolved. There is currently no “gold standard” for pain relief after total hip and knee replacement surgeries. An excellent ratio of effectiveness and safety is demonstrated by multimodal pain relief programs based on peripheral nerve blocks. However, while having undeniable advantages, conduction anesthesia/analgesia has a critically important drawback. The cornerstone of postoperative rehabilitation for patients undergoing total hip or knee replacement is their early activation. All methods of conduction anesthesia are associated with motor blockade. In particular, femoral nerve block causes weakness of quadriceps muscle of thigh, inducing patients’ inadvertent falling when attempting to stand or walk. The situation with the choice of the method of anesthesia after total replacement of the lower limb large joints can be described as “a long way to go”.
